HLA-C/KIR genotype linked to HBeAg-positive HBV interferon response

The human leucocyte antigen-C and killer immunoglobin-like receptor genotypes are associated with response to interferon-based therapy in patients with chronic hepatitis B virus infection positive for hepatitis B e antigen, say researchers.

Study reveals new activation mechanism for protein kinases

Protein kinases, most scientists would agree, regulate nearly every aspect of cell life. It is no surprise, then, that having faulty protein kinases may lead to a number of human conditions, including cardiovascular diseases, cancer and diabetes.

Study points to possible new genetic risk factor for celiac disease

Researchers have identified a common variant in a non-coding RNA that may contribute to the intestinal inflammation that occurs in people with celiac disease. The findings point to a possible new risk factor for developing celiac disease in people with celiac disease risk genes.

Researchers elucidate mechanisms underlying impaired ciliogenesis in PKD

In an article published online ahead of print on Feb. 19, 2015 in the Journal of Biological Chemistry, investigators at the Medical University of South Carolina and the Ralph H. Johnson VA Medical Center report findings from in vitro and in vivo studies that elucidate the mechanisms underlying the impaired ciliogenesis and abnormal kidney development characteristic of polycystic kidney disease (PKD).

PERK inhibition can be a promising therapeutic strategy for neurodegenerative diseases

A major challenge in the field of neurodegeneration is the unclear understanding of neuronal dysfunction. Elucidation of these patho-mechanisms could result in the identification of novel therapeutic targets. In this article, Bell et al. present an exhaustive literature review highlighting the endoplasmic reticulum (ER) kinase PERK as a crucial contributor to systemic and neurodegenerative disorders.

Delivering microRNAs in cancer treatment: an interview with Dr Conde and Prof Artzi

microRNAs (miRs) are small endogenous noncoding RNA molecules (20–23 nucleotides) derived from imperfectly paired hairpin RNA structures naturally encoded in the genome that act specifically as triggering molecules to control translational repression or mRNA degradation.

Russian scientists propose new technique to analyze intestinal metagenomes

A group of Russian scientists, among them staff at the Moscow Institute of Physics and Technology, have proposed a new method for the comparison of metagenome-coupled DNA sequences from all of the organisms in a sample of biological material being investigated.

Scientists discover novel drug candidate to treat breast cancer, lung cancer and melanoma

Using a new approach, scientists at The Scripps Research Institute and collaborating institutions have discovered a novel drug candidate that could be used to treat certain types of breast cancer, lung cancer and melanoma.

P53 genetic variant heavily implicated in metabolism, new research finds

The study may also provide an evolutionary explanation for differences in populations living farther away from the Equator. Human ancestors may have undergone this change in R72 to promote energy storage in cold climates and during times of famine. However, in modern society, the need for this type of variant in our genes is unnecessary, leading instead to increased risk for obesity and type 2 diabetes. Obesity is also a risk factor for certain types of cancer, so these findings may also explain why the R72 variant of p53 might predispose certain people to cancer.

Elevated levels of particular proteins in cancer cells fuel growth and spread of different cancers

Researchers at University of California, San Diego School of Medicine and Moores Cancer Center, with colleagues in Spain and Germany, have unraveled how elevated levels of particular proteins in cancer cells trigger hyperactivity in other proteins, fueling the growth and spread of a variety of cancers.

Penn researchers develop new mathematical model to estimate mutation rates in the human genome

It turns out that the type, how frequent, and where new mutations occur in the human genome depends on which DNA building blocks are nearby, found researchers from the Perelman School of Medicine at the University of Pennsylvania in an advanced online study published this week in Nature Genetics.

Study shows new RNA letter as regulatory key to control gene expression

DNA, RNA, protein -- the end. Or is it? Until recently, the pattern used to encode genetic information into our cells was considered to be relatively straightforward: four letters (A,G,C,T) for DNA and four (A,G,C,U) for RNA. This equation, however, turned out to be oversimplified -- RNA was holding out.

Neural gene promotes growth and spread of metastatic breast cancer

When breast cancer becomes advanced and spreads to other organs, patient survival is drastically reduced, prompting the need to explore the genes that may cause tumor cells to metastasize.

Pioneering technique shows promise for new medical diagnostics, targeted drug delivery

Living systems rely on a dizzying variety of chemical reactions essential to development and survival. Most of these involve a specialized class of protein molecules--the enzymes.

Scientists propose use of mathematical models to find better treatment for bladder cancer

MIPT scientists together with their colleagues from St. Petersburg and Israel have analyzed more than 500 previously published scientific articles and proposed their own approach to the choice of methods used for the treatment of one of the most common cancers.

Helpful protein can change genetic sequence of normal cells and make mutations that cause cancers

Washington State University researchers have determined how a protein that helps cells fight viruses can also cause genetic mutations that lead to cancer.

Temple team describes use of cadaver DNA to advance genetics learning in medical curriculum

Cadavers have long been one of the most important resources for anatomy teaching in medical school. Now, they are also at the forefront of cutting-edge genetics teaching, thanks to innovative thinking by professors at the Lewis Katz School of Medicine at Temple University.
