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.

Discovery may change thinking on how viruses invade the brain

A molecule thought crucial to ferrying the deadly rabies virus into the brain, where it eventually kills, apparently isn't.

Eradicating polio a better option than extended control of the disease

Concerns about the high perceived costs of eradicating the relatively low number of polio cases worldwide have led to recent suggestions that it is time to shift from a goal of eradication to control—abandoning eradication and allowing wild poliovirus to continue to circulate, which proponents of control believe can sustain the low number of cases.

Macaque genome analysis will improve scientists' ability to identify human genes involved in diseases

Cornell experts in computational biology and bioinformatics have made key contributions to the analysis of the genome of the rhesus macaque, better known as the rhesus monkey.

Link between immune system and high plasma lipid levels

Researchers at the University of Chicago have found an unsuspected link between the immune system and high plasma lipid levels (cholesterol and triglycerides in the blood) in mice.

Analysis of Rhesus monkey genome provides new clues to primate biology

An international consortium of researchers has published the genome sequence of the rhesus macaque monkey and aligned it with the chimpanzee and human genomes.

Breakthrough in photoswitchable fluorescent protein science

University of Oregon scientists have identified molecular features that determine the light-emitting ability green fluorescent proteins, and by strategically inserting a single oxygen atom they were able to keep the lights turned off for up to 65 hours.

Scientists at Johns Hopkins discover Solitary protein

Working with fruit flies, scientists at Johns Hopkins have discovered a protein required for two neighboring cells to fuse and become one "super cell."

How auxin regulates TIR1 in plants provides clues to new treatments for human diseases

For the first time, scientists from the University of Washington School of Medicine, Indiana University Bloomington and the University of Cambridge have determined how a plant hormone -- auxin -- interacts with its hormone receptor, called TIR1.

Geometry of viruses

A mathematician at the University of York has been awarded a Research Leadership Award of more than ,700,000 by the Leverhulme Trust to study the geometry of viruses.

Penn State scientists reveal structure of gateways to gene control

Scientists at Penn State University will reveal in the 29 March 2007 issue of the journal Nature the first complete high-resolution map of important structures that control how genes are packaged and regulated throughout an entire genome.

FDA clears Xpert EV test for meningitis

The U.S. Food and Drug Administration (FDA) has cleared for marketing a test that uses molecular biology to quickly detect the presence of viral meningitis.

Scientists decipher a signaling pathway crucially involved in Crohn's disease and ulcerative colitis

Inflammatory bowel diseases, such as Crohn's disease and Ulcerative Colitis, severely impair the lives of more than four million people worldwide. The development of effective therapies against these diseases requires an understanding of their underlying molecular mechanisms.

Australian researcher unveils pregnancy mystery

Belinda Hardman completed the study for her PhD with Deakin's Centre for Cellular and Molecular Biology under the supervision of Dr Leigh Ackland.

Chemoimmunotherapy versus chemotherapy for metastatic malignant melanoma

The addition of immunotherapy to chemotherapy for malignant skin cancer that has spread does not improve survival rates, researchers have found, and patients have more serious side effects, such as anemia, when the two treatments are combined.

First 3-D structure from key influenza protein revealed

In 1918, 50 million people died during a worldwide influenza pandemic caused by mutation of a bird-specific strain of the influenza virus. Recently H5N1, another highly infectious avian strain has caused outbreaks of bird flu around the world.

Gambian President claims to cure HIV/AIDS

Gambian President Yahya Jammeh since January has claimed that he can cure HIV/AIDS with an herbal remedy, prompting concern among some public health workers in Africa who already are "struggling against faith healers dispensing herbal remedies," the AP/Monterey County Herald reports.

New test identifies suitable lymphoma patients likely to respond to new therapy

Researchers at the Albert Einstein College of Medicine of Yeshiva University have discovered a genetic signature identifying cases of lymphoma that are uniquely susceptible to a newly developed molecular targeted therapy. As a result, physicians organizing clinical trials of the new therapy will be able to enroll patients who'll be most likely to benefit from it.

Search for vaccine to prevent Chlamydia

It's the most common bacteria-related sexually transmitted disease in the United States, so researchers at The University of Texas at San Antonio's South Texas Center for Emerging Infectious Diseases (STCEID) and The University of Texas at San Antonio Health Science Center have partnered to discover a vaccine that will prevent Chlamydia.

New targets in cancer mutation puzzle

University of Rochester scientists, while investigating the two most frequent types of mutations in cancer, discovered a possible new route to treatment that would take advantage of the mutations instead of trying to repair them.

HIV protein TAT used to pull protein Bim into cancer cells - helps kill cancer cells

Cancer cells are sick, but they keep growing because they don't react to internal signals urging them to die. Now researchers at Washington University School of Medicine in St. Louis have found an efficient way to get a messenger into cancer cells that forces them to respond to death signals. And they did it using one of the most sinister pathogens around - HIV.
