Molecular Biology News and Research

RSS

Molecular biology is the study of biology at a molecular level. The field overlaps with other areas of biology and chemistry, particularly genetics and biochemistry. Molecular biology chiefly concerns itself with understanding the interactions between the various systems of a cell, including the interactions between DNA, RNA and protein biosynthesis as well as learning how these interactions are regulated.

Monell Center announces advocacy program to identify biological causes of smell loss

On Anosmia Awareness Day, the Monell Center announces "A Sense of Hope: The Monell Anosmia Project," a three-year $1.5M fundraising campaign to support a research and advocacy program focused on anosmia, the loss of the sense of smell.

New study shows increase in certain macrophages may lead to therapeutic targets for Crohn's disease

For those coping with Crohn's disease, a new research report published in the Journal of Leukocyte Biology offers hope for the development of new and more effective drugs. In the report, scientists show for the first time, precisely what type of immune cells are involved in driving the inflammation process in the disease.

New theory on the causation of type 2 diabetes

At 85, Nobel laureate James D. Watson, the co-discoverer of the double-helix structure of DNA, continues to advance intriguing scientific ideas. His latest, a hypothesis on the causation of type 2 diabetes, is to appear 7 pm Thursday US time in the online pages of The Lancet, the prestigious British medical journal.

3D structure of enzyme helps defend against bacteria

An essential weapon in the body's fight against infection has come into sharper view. Researchers at Princeton University have discovered the 3D structure of an enzyme that cuts to ribbons the genetic material of viruses and helps defend against bacteria.

Researchers discover novel treatments for psoriasis that are likely to cause fewer side effects

Almost ten years ago, the group led by Erwin Wagner, currently at the Spanish National Cancer Research Centre (CNIO), developed genetically modified mice showing symptoms very reminiscent to psoriasis.

Silver nanoparticles in dietary supplements, cosmetics and food packaging can cause damage to cells

Endocrine disrupters are not the only worrying chemicals that ordinary consumers are exposed to in everyday life. Also nanoparticles of silver, found in e.g. dietary supplements, cosmetics and food packaging, now worry scientists.

Link found between pollutants and certain metabolic complications of obesity

A team of researchers at the IRCM in Montr-al led by R-mi Rabasa-Lhoret, in collaboration with J-r-me Ruzzin from the University of Bergen in Norway, found a link between a type of pollutants and certain metabolic complications of obesity. Their breakthrough, published online this week by the Journal of Clinical Endocrinology & Metabolism, could eventually help improve the prevention, diagnosis, and treatment of cardiometabolic risk associated with obesity, such as diabetes, hypertension and cardiovascular disease.

Researchers discover how byproducts from bacteria prevalent in gum disease incite growth of deadly tumors

Researchers from Case Western Reserve University have discovered how byproducts in the form of small fatty acids from two bacteria prevalent in gum disease incite the growth of deadly Kaposi's sarcoma-related (KS) lesions and tumors in the mouth.

Research grows "mini-livers" to reduce use of animals in science

Research that has for the first time successfully grown "mini-livers" from adult mouse stem cells has won the UK's international prize for the scientific and technological advance with the most potential to replace, reduce or refine the use of animals in science (the 3Rs).

Researcher identifies ''conductor'' in development of muscle tissue

A team led by Jean-Fran-ois C-t-, researcher at the IRCM, identified a ''conductor'' in the development of muscle tissue. The discovery, published online yesterday by the scientific journal Proceedings of the National Academy of Sciences (PNAS), could have an important impact on the treatment of muscular diseases such as myopathies and muscular dystrophies.

New DNA Quantification kits may help scientists to quickly assess highly compromised human DNA

Forensic scientists can now more quickly assess the quantity and quality of human DNA in highly compromised and degraded casework samples and provide the critical information needed to drive informed decisions on subsequent steps in the analysis process, thanks to two new Life Technologies quantification solutions announced today by Thermo Fisher Scientific.

Two New York University faculty receives fellowships from Alfred P. Sloan Foundation

Two New York University faculty have been awarded fellowships from the Alfred P. Sloan Foundation: Roozbeh Kiani, an assistant professor at NYU's Center for Neural Science, and Nicholas Stavropoulos, an assistant professor of neuroscience and physiology at NYU Langone Medical Center and its Neuroscience Institute.

Small non-coding RNAs can help predict individuals with breast cancer

Small non-coding RNAs can be used to predict if individuals have breast cancer conclude researchers who contribute to The Cancer Genome Atlas project. The results, which are published in EMBO reports, indicate that differences in the levels of specific types of non-coding RNAs can be used to distinguish between cancerous and non-cancerous tissues. These RNAs can also be used to classify cancer patients into subgroups of individuals that have different survival outcomes.

Subtle epigenetic change plays important role in correct segregation of chromosomes

Abnormal number of chromosomes is often associated with cancer development. In a new study published in the journal Nature Structural and Molecular Biology researchers at Karolinska Institutet in Sweden have shown that a subtle epigenetic change plays an important role in the correct segregation of chromosomes.
