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.

New strategy can reactivate genes that cause cancer tumors to shrink and die

A team of scientists has developed a promising new strategy for "reactivating" genes that cause cancer tumors to shrink and die. The researchers hope that their discovery will aid in the development of an innovative anti-cancer drug that effectively targets unhealthy, cancerous tissue without damaging healthy, non-cancerous tissue and vital organs.

Study demonstrates impact of epilepsy on child and parent sleep patterns

Researchers from Massachusetts General Hospital for Children in Boston have determined that pediatric epilepsy significantly impacts sleep patterns for the child and parents. According to the study available in Epilepsia, a journal published by Wiley-Blackwell on behalf of the International League Against Epilepsy (ILAE), sharing a room or co-sleeping with their child with epilepsy decreases the sleep quality and prevents restful sleep for parents.

TJU researchers to investigate Cu-64 imaging agent for prostate cancer

Jefferson's Kimmel Cancer Center and the Department of Radiology at Thomas Jefferson University received a five-year, $2.6 million grant from the National Institutes of Health (NIH) to investigate a potentially revolutionary method that can stage prostate cancers and detect recurrent disease so accurately, it would significantly reduce the number of confirmation biopsies. Such biopsies can be invasive, costly, and often lead to false-positive readings.

JHSPH wins GCE grant for global health and development research project

The Johns Hopkins Bloomberg School of Public Health announced today that it is a Grand Challenges Explorations winner, an initiative funded by the Bill & Melinda Gates Foundation. Alain Labrique, PhD, director of the Johns Hopkins University Global mHealth Initiative, will pursue an innovative global health and development research project, titled "mTIKKA - Harnessing a Mobile - Cloud System to Achieve Universal Vaccination."

KLF15 molecule inhibits action of estrogen in the endometrium

Researchers at Albert Einstein College of Medicine of Yeshiva University have discovered a molecule that inhibits the action of estrogen. This female hormone plays a key role in the growth, maintenance and repair of reproductive tissues and fuels the development of endometrial and breast cancers.

NCKU student receives Graduate/Postdoctoral Travel Award from ASBMB

Wan-Pei Su, a graduate student of Molecular Medicine at National Cheng Kung University (NCKU), southern Taiwan, has received a Graduate/Postdoctoral Travel Award from the American Society for Biochemistry and Molecular Biology (ASBMB) to attend the annual conference on Experimental Biology (EB) in San Diego in April 2012.

Scientists pinpoint mechanism essential for memory formation

Now, in a study that appears in the May 10, 2012 issue of the journal Neuron, scientists from the Florida campus of The Scripps Research Institute have pinpointed a mechanism that is essential for forming memories in the first place and, as it turns out, is equally essential for eliminating them after memories have formed.

G&D, IAVI and GMI partner to develop new HIV/AIDS vaccine

The International AIDS Vaccine Initiative (IAVI), GlycoMimetics, Inc. (GMI), and Glycosensors and Diagnostics, LLC (G&D) today announced a collaboration to develop an AIDS vaccine using novel compounds that mimic carbohydrates, called glycomimetics.

'Good' cholesterol may not protect against coronary heart disease

A new study by Harvard School of Public Health (HSPH) researchers has found that a subclass of high-density lipoprotein (HDL) cholesterol, the so-called "good" cholesterol, may not protect against coronary heart disease (CHD) and in fact may be harmful.

Automated way to record electrical activity inside neurons in the living brain

Gaining access to the inner workings of a neuron in the living brain offers a wealth of useful information: its patterns of electrical activity, its shape, even a profile of which genes are turned on at a given moment. However, achieving this entry is such a painstaking task that it is considered an art form; it is so difficult to learn that only a small number of labs in the world practice it.

New system measures strength of communication between muscle cells and motor neurons

In an effort to identify the underlying causes of neurological disorders that impair motor functions such as walking and breathing, UCLA researchers have developed a novel system to measure the communication between stem cell-derived motor neurons and muscle cells in a Petri dish.

Dilp8 provides an important signal to slow body growth and delay insect development

Two independent groups of researchers have identified a hormone that is responsible for keeping the growth and development of insects on track. The results, which are reported in the journal Science, suggest that Dilp8 provides an important signal to slow body growth and delay insect development.

HSPH introduces Obesity Prevention Source website

What is causing the obesity epidemic-and how can we stop and reverse this worldwide weight problem? A new website offers authoritative answers to these pressing questions and sheds light on one of the most challenging public health threats of our time.

Scientists identify how cell architecture changes during formation of gametes

Scientists using high-powered microscopes have made a stunning observation of the architecture within a cell - and identified for the first time how the architecture changes during the formation of gametes, also known as sex cells, in order to successfully complete the process.

Researchers discover how protein ARTD1's DNA recruitment is regulated during inflammation

During inflammation, controlled gene expression is necessary in order to allow the organism to mount an effective defense response. For this process, the protein ARTD1 is removed from the DNA.

Cancer genomes in a common database and computation of disease drivers

The emerging field of "personalized" or "precision" medicine holds great promise in the fight against cancer. If scientists can identify the genetic changes that drive each patient's cancer cells, they can use that information to develop targeted treatments. But achieving this goal will require massive amounts of genomic and clinical data and a sophisticated infrastructure to manage and analyze the data.

Vitamin D strengthens innate immunity against viral infections

Vitamin D may be known as the sunshine vitamin, but a new research report appearing in the Journal of Leukocyte Biology shows that it is more than that. According to the report, insufficient levels of vitamin D are related to a deficiency in our innate immune defenses that protect us from infections, neoplasias or autoimmune diseases.
