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 computational method uses biological networks to better identify relationships between molecules

Scientists at the Samuel Lunenfeld Research Institute of Mount Sinai Hospital (Canada), European Molecular Biology Laboratory (Germany), and Massachusetts Institute of Technology (USA) have created a new computational method called NetworKIN.

Researchers shed light on shrinking of chromosomes

A human cell contains an enormous 1.8 metres of DNA partitioned into 46 chromosomes.

New Rochester program to coordinate patient care, research for patients suffering with brain and spinal tumors

The University of Rochester Medical Center and its Department of Neurosurgery are establishing a new multidisciplinary program to coordinate patient care, research and community outreach efforts for patients suffering with brain and spinal tumors.

New understanding of anti-malarial drug resistance

Researchers at Georgetown University Medical Center say they are moving closer to understanding why the most lethal form of human malaria has become resistant to drug treatment in the past three decades.

Mouse hibernation hormones described

A key hormone enables starving mice to alter their metabolism and “hibernate” to conserve energy, revealing a novel molecular target for drugs to treat human obesity and metabolic disorders, UT Southwestern Medical Center researchers have found.

Neural basis for anxiety behaviour discovered

People who suffer from anxiety tend to interpret ambiguous situations, situations that could potentially be dangerous but not necessarily so, as threatening.

Combining molecular imaging technologies to stop/prevent heart attacks

The use of combined imaging technologies may hold the key to stopping and even preventing heart attacks, according to research reported at the 54th Annual Meeting of SNM, the world's largest society for molecular imaging and nuclear medicine professionals.

Scientist's discovery of role of Aquaporin in spinal injuries recognized with research funding award

Dr. Olivera Nesic-Taylor, an assistant professor in biochemistry and molecular biology at the University of Texas, Galveston, was presented with the Erica Nader Award for 'breakthrough research in spinal cord regeneration.'

New discoveries on genes implicated in Fanconi anaemia

An international research consortium, which included the participation of the Mutagnesi Group from the UAB, has made outstanding progress in the study of Fanconi anaemia.

New hypothesis on Alzheimer's disease

Researchers at Rensselaer Polytechnic Institute are challenging current thinking on the causes and prevention of Alzheimer's disease, offering a new hypothesis that could be the key to preventing this form of dementia.

Breakthrough in understanding how cancers spread

The University of Manchester study used embryonic stem (ES) cells to investigate how some tumours are able to migrate to other parts of the body, which makes the treatment of cancer much more difficult.

Scientists evolve new proteins from scratch

Nature, through the trial and error of evolution, has discovered a vast diversity of life from what can only presumed to have been a primordial pool of building blocks.

Scientists convert the sequence of proteins into music

UCLA molecular biologists have turned protein sequences into original compositions of classical music.

New findings on microRNAs

Over 30% of our genes are under the control of small molecules called microRNAs.

New compounds promising candidates for neurodegenerative disease drug development

Scientists have developed a novel strategy for tackling neurodegenerative diseases such as Huntington's disease: encouraging an individual's own cells to "eat" the malformed proteins that lead to the disease.

Scientists work out mechanism underlying asymmetric cell division in nematode worms

When a cell divides, normally the result is two identical daughter cells. In some cases however, cell division leads to two cells with different properties. This is called asymmetric cell division and plays an important role in embryonic development and the self-renewal of stem cells.

Nanoparticles found near plaque-filled arteries

Scientific evidence increasingly links arterial calcification to the presence of nanosized particles so small that some scientists question whether a nanoparticle can live and, if so, play a viable role in causing disease.

Scientists find last unknown enzyme in the synthesis of vitamin C in plants

Vitamin C is possibly the most important small molecule whose biosynthetic pathway remained a mystery.

The convergence of embryonic and cancer signaling pathways: role in tumor cell plasticity

In earlier work, Northwestern University scientist Mary J.C. Hendrix and colleagues discovered that aggressive melanoma cells (but not normal skin cells nor less aggressive melanoma cells) contain specific proteins similar to those found in embryonic stem cells.

Exercise pill switches on master regulator that controls the ability of cells to burn fat

By giving ordinary adult mice a drug - a synthetic designed to mimic fat - Salk Institute scientist Dr. Ronald M. Evans is now able to chemically switch on PPAR-d, the master regulator that controls the ability of cells to burn fat.
