Clin Epigenet: Specific Epigenetic Markers Expected to Reveal Mechanisms of Progression and Metastasis in Various Cancers

In a recent study published in the Clinical Epigenetics entitled "Characterization of DNA methylation changes in EBF3 and TBC1D16 associated with tumor progression and metastasis in multiple cancer types," scientists from the University of Otago have identified a variety of cancer cell biomarkers that may help clinicians identify which cancer cells are more likely to spread to other parts of the body.

The results of this study may provide clinicians and patients with more clear ideas to elucidate the mechanism of cancer cell spread and how to use effective therapies for the treatment of different types of cancer at a later stage. Early detection of the rate of cancer spread may help improve the prognosis of cancer patients, said researcher Euan Rodger.

In most patients who die of cancer, the spread of cancer from one organ to another is often considered highly lethal, and tracking the spread of cancer has become an important weapon against cancer. In the study, researchers wanted to see if new molecular changes existed in other types of cancer cells, albeit with some confusion, but in general, the researchers got the answers they wanted.

Based on the results of this study, the researchers are expected to develop novel strategies to track the therapeutic effects of cancer patients in the future; next, researchers will also continue to conduct in-depth studies to find more epigenetic markers to reveal the mechanisms of progression and metastasis of many types of cancer.

Proteins Identified as Key to Stem Cell Production

A multinational team of scientists led by Professor Benjamin Blencowe of the University of Toronto has identified proteins that play a key role in the control of pluripotency, which may mean a possible breakthrough in the production of so-called induced pluripotent stem cells.

Induced pluripotent stem cells are of great value for medical research because they can flexibly develop into many different types of cells. However, producing these cells is challenging because the proteins that control their production are largely unknown

The team discovered these proteins using a tiling code developed by Professor Blencowe several years ago.

"The mechanisms that control embryonic stem cell pluripotency have been a mystery for some time," explains Dr. Brendan Frey, also from the University of Toronto, who co-authored the study published in the journal Nature.

"However, Professor Blencowe and his team found that the proteins identified by our splicing code can activate or reduce the pluripotency of stem cells."

"Suppose you've tasted a lot of delicacies, but you have no idea what it takes to make them. Then, one day, you will find that all gourmet food cooks will use something called a "measuring cup". Now you know important information about how to prepare dishes, and you know the "control knobs" that can be turned to make different dishes, just as adjusting the amount of butter and flour produces different kinds of pastries.

Dr Frey said: "Although the complete formula for producing induced pluripotent stem cells may not yet be available, it looks more likely at first."

Nature: Protein OTX2 Plays a Crucial Role in Germ Cell Development

In a new study, researchers from the University of Edinburgh in Scotland, Shandong University in China, and the Institute of Genetics and Biophysics in Naples, Italy, discovered key insights into how sperm cells (ie, sperm) and egg cells (eggs) are formed, thus helping to reveal their earliest stages of development. This study is the first to show how proteins affect the fate of these cells that determine the DNA profile of the offspring. The relevant research results were published online in the Nature recently, and the paper titled "OTX2 restricts entry to the mouse germline".

These findings focus on the development of germ cells that produce sperm and eggs. During reproduction, germ cells from different sexes fuse together to form new individuals.

These researchers used mice as the research object to explore the first stage of germ cell formation. They focused on a molecule called BMP4 that was found to block the activity of Otx2, a gene regulator that directs the development of non-germ cells (called somatic cells). They demonstrated that lowering Otx2 activity by BMP4 is critical for germ cell development.

Professor Ian Chambers of the University of Edinburgh said, "Before, the study of germ cell identity focused on a series of events that occurred during germ cell development. We are now able to begin to observe early events that occur during germ cell development. These exciting discoveries open the door to a better understanding of the earliest stages of controlling the separation of germ cells from all other cells."

As leading biotech provider, Creative BioMart also provides quality OTX2 products, BMP4 products, etc. for the science community. 

Nat Commun: New Ways to Reduce the Side Effects of Cancer Drugs

Protein research is one of the hottest areas of medical research because protein-based drugs can be developed to treat diabetes, cancer and other diseases.

Although proteins have great potential, their incredibly complex chemical structures pose enormous challenges for scientists. As a result, researchers have been looking for a tool to modify them more precisely, thereby reducing the side effects of the drug.

Recently, researchers have developed a new protein modification method that can reduce the side effects of drugs and can be the key to promoting the development of protein drugs. Their research has been published in Nature Communications.

Protein structure is like an intricate yarn ball

Researchers call this method "His-tag acetylation." In addition, it can add toxic molecules to proteins that attack diseased cells in the body of cancer without attacking healthy cells.

“Protein is like a ball of yarn. When they are opened, a long chain of amino acids will appear. This new modification allows us to precisely target these intricate structures. In short, it will help the drug production, and we can make changes more confidently so that we can reduce side effects in the future," the author said.

Modified proteins must be pinpointed

His-tag acylation accurately targets these complex yarn-like protein structures, which also makes it possible to produce drugs with novel properties.

For example, researchers can now attach fluorescent molecules to proteins, allowing microscopy to track the path of proteins through cells. Since the primary function of these proteins is to transport anticancer molecules around the diseased cells, it is important to follow their path carefully throughout the body.

As a leading biotech supplier, Creative BioMart provides quality protein modification services to its valued customers including: Protein Acetylation Assay, Protein Glycosylation Service, Protein Kinase Assay, Protein Methylation Assay, Protein Ubiquitinylation Service, Protein Deubiquitination Assay, and Protein SUMOylation Assay.

Molecular Cancer: Researchers Find New Targets for Breast Cancer

A study led by Dr. Suresh Alahari, professor of biochemistry and molecular biology at the University of Louisiana Health Science Center (LSU Health), first discovered that a small piece of RNA can dysregulate cellular energy metabolism, which is a major feature of cancer. These findings have found a new target for therapeutic intervention in breast cancer, and the findings are recently published in Molecular Cancer.

MicroRNAs are a class of single-stranded small RNA molecules that play important regulatory roles in cell biology, and they bind to target genes to reduce their function. MicroRNAs can be used both as a carcinogen and as a tumor suppressor.

The research team has previously found that miR-27b is a breast cancer carcinogen, and researchers have found it to be high in breast cancer tissue. In this study, the researchers found that this molecule inhibited the production of a protein called PDHX. PDHX involves cellular metabolism, and cellular metabolism can affect cell proliferation. Lack of PDHX means that cells can rapidly produce new cells and promote tumor growth and progression. The team found a significant reduction in PDHX levels in breast cancer cells.

"Based on these data, we believe that inhibition of miR-27b is a new treatment for breast cancer," Dr. Alahari said. "Inhibition of miR-27b promotes PDHX expression, which inhibits tumor proliferation through several established metabolic cascades."

According to NCI statistics, the number of new breast cancer patients in the United States will be higher than other cancers in 2018. NCI estimates that there will be 266,120 new cases of breast cancer, and 40,920 will die from breast cancer. "The use of microRNA analogs or anti-microRNA agents will counteract their function, and reversing oncogene metabolism will be a unique cancer treatment strategy. Potential clinical applications of miRNAs include diagnostic tests, disease prevention, and prognostic markers, which make miRNAs a unique and attractive option for reducing cancer morbidity and mortality."

CDK6—the Hot Potato in Cancer Treatment

It is well known that the formation of tumors is a multi-step process in which cells acquire genetic and epigenetic changes during tumorigenesis and eventually reach a state of complete transformation. The cell cycle kinase CDK6 has received a lot of attention in the past few years. It is not only a cell cycle-dependent kinase but also a transcriptional regulator with functional characteristics different from the same family of CDK4. CDK6 regulates the expression of many genes, and some studies have found that this molecule can promote the development of malignant blood diseases such as AML and ALL, and is also important for the self-sustaining of hematopoietic stem cells and leukemia stem cells.

Recently, researchers from Vienna reported that CDK6 is able to antagonize p53-induced responses. Previous studies have found that high and low expression of CDK6 are associated with poor prognosis, but the reasons for this have not been revealed. In this study, the researchers found that CDK6 promotes tumor formation by regulating transcriptional responses at specific stages. In the early stages of tumorigenesis, CDK6 kinase prevents p53 from acting in hematopoietic cells by inducing a complex transcriptional program. Cells lacking CDK6 kinase function require the presence of TP53 mutations to achieve a fully transformed immortal state.

The researchers found that CDK6 binds to promoters of many genes, including p53 antagonists Prmt5, Ppm1d and Mdm4. The researchers said the findings of the study were also confirmed in patients: the frequency of TP53 mutations in tumors expressing low levels of CDK6 was higher than expected. The study found that CDK6 can promote cell cycle progression to antagonize stress responses and affect the effects of p53 and RB. Specific inhibition of CDK6 kinase activity results in cells more susceptible to p53-induced cell death and also stimulates the growth of p53 mutant clones in precancerous cells.

EiF4E and Depression

A recent study about changes in the brain linked to depression paved the way for new therapies. Moreover, the study also revealed why a certain antidepressant drugs stop working in some people.

Scientists from the University of Edinburgh studied mice that were bred to have defects in their ability to activate a certain molecule, called eIF4E. And it turned out that those animals showed signs of depression, reduced levels of hormone serotonin and also disinterest in food.

Treatment with a commonly prescribed antidepressant called fluoxetine failed to produce a response in the mice. This suggests that activation of eIF4E is required for the beneficial antidepressant effects of fluoxetine, which belongs to a category of medicines called selective serotonin re-uptake inhibitors (SSRIs). (sciencedaily.com)

This, however, could help explain why some patients stop responding to SSRIS. Previous studies have shown the effect of eIF4E in regulating protein synthesis in the brain. And the defects of eIF4E are also linked to other neurological conditions. But it is the first time it has been found to be connected with depression.

Those findings, according to the scientists, could help develop novel therapy for depression, which are affecting increasing numbers of people worldwide.

Dr Christos Gkogkas, a Chancellor's Fellow in the University of Edinburgh's Center for Discovery Brain Sciences, stated: “Our investigation uncovers that changed protein synthesis through eIF4E is a key cellular process in the brain that can go amiss in depression. Imperatively it might clarify why a few people with depression wind up resistant to treatment with SSRIs. This information can enable us to plan another generation of antidepressants.”

New Findings about IL-33 You May Want to Know

A team of researchers from the French Scientific Research Center and the National Institute of Health and Medical Research discovered that a protein acts like a sensor can detect asthma-inducing allergens in the respiratory tract. Their research, co-led by Corinne Cayrol and Jean-Philippe Girard, was recently published in Nature Immunology and has brought new breakthroughs in the treatment of allergic diseases.

What are the common features of mold, pollen, and wolfberry? Although they belong to three different organisms, they all can cause allergies in susceptible people. Although the composition varies greatly, they all contain enzymes called proteases.

The team found a human protein that reacts with environmental allergens: interleukin-33 (IL-33). When allergens enter the human respiratory tract, they release proteases that activate IL-33 to become extremely active. This triggers an allergic chain reaction.

At the same time, this mechanism has led to allergic reactions to various allergens. IL-33 can detect 14 different allergens, including environmental air (such as pollen, indoor aphids, fungal spores, etc.) and occupational asthma-related (like subtilisin found in detergents) allergens.

These findings are important because they find a direct relationship between genes and the environment. In fact, the gene encoding IL-33 is indeed one of the major genes that cause people to easily develop asthma. In addition, clinical trials targeting IL-33 are ongoing. Inhibiting the production of activated IL-33 after exposure to allergens may be an effective way to control severe allergic reactions in allergic patients.

The Amaryllidaceae Alkaloid Helps Repress Cancer Cell Growth

Daffodil can quickly cure cancer? Scientists from the Laboratory of RNA Molecular Biology at the Liberal University School of Science and Cancer Research Center in Brussels, Belgium, conducted a preliminary exploration in this direction, and this study was published in Cell's Structure recently.

The study, led by Denis Lafontaine, extracted a natural anticancer compound from daffodil (Amaryllidaceae). They found that the compound is an alkaloid called tennis amine, which binds ribosomes. Ribosomes are nanodevices necessary for the survival of our cells because they synthesize all of our proteins. In order to maintain their own unrestricted growth, cancer cells rely on enhanced protein synthesis, so cancer cells are very sensitive to therapies that inhibit ribosome formation or inhibit ribosomal function.

In the new study, researchers also found that tennis amine can inhibit ribosome-forming proteins and therefore slow cancer cell growth. Peracetamol also inhibits the production of such nanodevices in the nucleus: the pressure on the nucleolus activates the anti-cancer watchdog pathway, leading to increased stability of the p53 protein, thereby eliminating cancer cells.

This study, for the first time, reveals the molecular mechanism of antitumor activity of daffodils, which has been used in folk medicine for hundreds of years. Pedigree is a member of a large group of natural therapeutic molecules: Many of the other alkaloids used in human care are extracted from plants such as morphine (potent analgesics), quinine (anti-malaria drugs), and ephedrine (anti-asthma Medicine) and so on.

In the near future, Denis Lafontaine's team will work with Veronique Mathieu's team to examine the effects of four Amaryllid alkaloids on ribosome formation and function. Their goal is to quickly find the most promising chemical framework, and then further develop anticancer drugs.

JCI: Histone Protein Modifications May Regulate Human Glomerular Disease

During normal development, histone modifications control the fate of cells, whereas histone modification affects the process of cell dedifferentiation in the event of disease. In a recent study published in the international journals JCI, researchers from Canada decided to find out how dynamic changes in histone modifications can affect adult glomerular podocytes, which are usually at rest.

To do this, the researchers altered the inhibitory effect of H3K27me3 in podocytes and performed a series of analyzes. Adriamycin nephrotoxicity test and subtotal nephrectomy both showed that the level of H3K27me3 decreased after the removal of methyltransferase EZH2 with histone methylation in podocytes and the mice were susceptible to glomerular diseases. The researchers found that in podocytes H3K27me3 aggregates in the promoter region of Notch ligand Jag1, and inhibition of Jag1 by EZH2 knockdown or knockdown of EZH2 expression can promote podocyte dedifferentiation. In contrast, inhibition of the demethylase Jmjd3 and UTX increased the level of H3K27me3, decreased adriamycin nephrotoxicity experiments, subtotal nephrectomy, and diabetic-induced glomerular disease. In addition, the researchers analyzed glomerular podocytes in patients with focal segmental glomerulosclerosis and diabetic nephropathy and found that glomerular podocytes in these patients exhibited levels of H3K27me3 Decline and UTX levels increase. Similar to this observation, inhibition of Jmjd3 and UTX slows the progression of nephropathy in a mouse model of glomerular damage.

Collectively, these results indicate that chromatin modifications are not as stable as they appear to be at rest, and also undergo dynamic regulation, whereas epigenetic reprogramming or results that may improve glomerular disease.

Engineered Proteins Created to Treat Obesity

According to the material provided by American Association for the Advancement of Science, Scientists here have created engineered proteins that brought down body weight, bloodstream insulin, and cholesterol levels in obese mice, rats and primates. These findings, to some extent, pave the way for earnestly required alternatives to bariatric surgery for treating obesity in humans-the rates of which have almost tripled worldwide since 1975.

In view of the perception that obese mice, rats, and humans all had raised serum concentrations of a protein named GDF15 in contrast with learn controls, Yumei Xiong and partners set out to create treatments got from the molecule. In various mouse models of diet-induced and genetic obesity, conveyance of the GDF15 gene reduced body weights, food intake, and serum insulin levels in the animals.

Since GDF15 has a short plasma half-life and is hard to deliver in substantial quantities, the researchers produced two distinctive fusion proteins that were more stable in the circulation and prompted higher yields. Both fusion proteins adequately diminished body weights for obese mice and cynomolgus monkeys.

What’s more interesting is that, Xiong, together with her colleagues, additionally demonstrated that the GDF15 regimen changed food preferences in mice—driving the animals to pick lower calorie chow when offered a decision between standard food and an additional condensed-milk diet.

The authors established that GDF15 enacted a population of nerve cells called AP neurons that make up a portion of the gut-brain axis, yet take not of that further investigations to identify the protein’s cellular receptor are required as potential therapeutics advance toward the clinic.

As a quality protein products supplier, Creative  BioMart not only provides GDF15 proteins, but also GDF11 proteins, and other protein products and protein-related services to assist scientists with their research.

Trying to Find Membrane Protein Service?

Membrane proteins, proteins that interact with biological membranes, accounts for nearly half of know drug targets. It is estimated that almost 20-30% of all genes in most genomes encode membrane proteins. Membrane proteins as receptors and ion channels are vital regulators of cellular function and all of them are of great pharmaceutical importance.

The statistics of a recent survey may illustrate this well. The survey was meant to figure out the proportion of the classes of drug target in current drug therapies. And the results are as follows: receptors accounts for nearly half of the human drug targets and acting as therapeutic targets for a wide of disease conditions like: cancer and cardiovascular; following are enzymes which cover almost 30%; the third place was taken by hormones & factors; and ion channels take 5% of it. That is to say membrane protein account over 50% of the human drug target. So the importance of it is obvious.

To Know More about Two-hybrid System

The two-hybrid system is a genetic method that utilizes transcriptional activity as a measure of protein-protein interaction. It depends on the secluded way of site-specific transcriptional activators, which comprise of a DNA-restricting area and a transcriptional actuation space. The DNA-restricting space serves to focus on the activator to the promoter district of particular qualities, and the enactment area contacts different proteins of the transcriptional hardware to empower translation to happen. The two-cross breed framework depends on the perception that the two areas of the activator don't need to be covalently connected and can be united by the collaboration of any two communicating proteins.

The application of this system requires two hybrids to be constructed: a DNA-restricting area intertwined to one protein, X, and a translation initiation space combined to another protein, Y. Those two hybrids are expressed in a cell containing one ore more reporter genes. One the off chance that the X and Y proteins cooperate, they make a functional activator by bringing the activation domain into close proximity to the DNA-binding domain, that can be identified by articulation of the reporter gene. While the assay has been generally performed in yeast cells, it works correspondingly in mammalian cells. Co-expression of proteins for the determination and characterization of protein interactions is achieved with Yeast Two-Hybrid technology.

With its various features, two-hybrid system is regarded as a quite useful tool for the analysis of protein-protein interactions. For example, it is highly sensitive, and is capable of detecting interactions that can not be detected by other methods. 

Mostly regularly utilized versions of the two-hybrid system all involve DNA-binding domains that get from the yeast Ga14 protein or the E. Coli LexA protein. Transcriptional activation domains are commonly derived from the Ga14 protein or the herps simplex virus VP16 protein. Reporter genes include the E. Coli lacZ gene and selectable yeast genes, for example: HIS3 and LEU2. An expanding number of activation domain libraries are now achievable for proteins from a wide range of creatures or particular mammalian tissues.

As a leader specialized in protein interaction analysis, Creative BioMart has acquired long experience and expert knowledge in protein interaction study.

Yeast Expression System Service in Creative BioMart

Yeast systems have been a staple for producing large amounts of proteins for industrial and biopharmaceutical use for many years. It is the most economical eukaryotic expression system for both secretion and intracellular expression. And it’s ideally suitable for large-scale production of recombinant eukaryotic proteins.

Take advantage of Creative BioMart's proprietary YeastXceedTM Technology, selected stable and durable production strains that resemble mammalian system are employed for high-yield, high-productivity protein processing, thus dramatically reducing the associated costs and inherent time requirements.

With expertise in protein expression spanning both P. pastoris and S. cerevisiae expression systems, Creative BioMart is the right choice for protein production via fed-batch pichia processes. The company’s staff can move help move your project forward.

Engineering-enhanced protein expression technologies in Creative BioMart will enable a high success rate over 95% over various recombinant proteins. And the proprietary YeastXceedTM technology is pushing the yields even higher. Many secretory proteins that bacterial expression systems yield as insoluble or as inactive inclusion bodies can be produced successfully by the company’s yeast expression system using native or yeast secretion signals.

In the past years, we have identified DNA elements that are instrumental in increasing translation rates when included in recombinant protein expression vectors. These elements are functional across eukaryotic production platforms, including mammalian cells, yeast and most fungal systems. On the basis of these elements, the company developed proprietary HostOptimTM technology that has been confirmed for a wide variety of industry relevant platforms.
