Molecular Biology News and Research

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 of how protein in teeth controls bone-like crystals to form steely enamel

Bone and enamel start with the same calcium-phosphate crystal building material but end up quite different in structure and physical properties.

Replication timing assays may allow much earlier cancer detection

Scientists have discovered a DNA sequence that is involved in controlling the timing of DNA replication. Because alterations in DNA replication timing are associated with cancer, this discovery may lead to improved methods for cancer detection.

Genome researchers to look at 1918 Spanish flu

University of Washington researchers will be taking part in a multi-site project examining a portion of the genome of the strain of influenza responsible for the "Spanish Flu" outbreak in 1918.

Protein points to anticancer drug targets

A unique tail at one end of a protein called Ubc12 stabilizes a molecular workshop that assembles the “on-switch cells” used to accelerate cell replication.

New insights into ancient mating and migration patterns in humans

Men have been tomcatting around since time immemorial, and some traveled far from home to do it, new research suggests.

Crohn’s disease may be caused by same bacterium that causes Paratuberculosis or Johne’s disease in cattle, sheep, and goats

A study in this week’s issue of THE LANCET suggests that Crohn’s disease may be caused by Mycobacterium avium subspecies paratuberculosis (MAP), the same bacterium that causes a similar intestinal disorder (known as Paratuberculosis or Johne’s disease) in cattle, sheep, and goats.

A new vector of malaria in Africa called Oveng form

Malaria affects around 600 million people in the world and leads to an annual death toll of over 2 million. It is the world’s most widespread parasitic disease.

Researchers are making inroads to understanding what makes brain tumors so hard to treat

When he's not in the operating room performing surgery, Donald M. O'Rourke, M.D., Associate Professor of Neurosurgery at the University of Pennsylvania School of Medicine is fighting brain tumors from the research laboratory bench.

Researchers have discovered a possible way to distinguish lethal from localized prostate cancers

If future studies show their test -- measuring the level of activity of a signaling pathway called Hedgehog -- can predict which prostate cancers will spread, the results could revolutionize decision making processes for prostate cancer patients, the researchers say.

Suprising new information on the HOX genes

Researchers at the University of Bergen are now able to present new information on the HOX genes – the “software” to design animals. The findings are published in today’s issue of Nature.

Advances in gene silencing on the agenda

Recent advances in using 'RNA interference' (RNAi) to improve plant, animal and human health will be the major focus of the CSIRO-hosted Horizons in Livestock Sciences Conference on the Gold Coast from 12-15 September.

Circadian rhythm research may lead to greater understanding of jet lag and human diseases

Our biological clock, or circadian rhythm, is upset by travelling across time zones, but very soon the body adjusts to the new day/night cycle.

Mouse stem cells may help restore hearing loss in humans

The work is important because, in humans, inner ear sensory hair cells are a precious commodity. Humans are born with only about sixteen thousand of these sound detectors in each ear, which can be easily damaged by age, certain illnesses, exposure to loud sounds, and some medications. Once damaged, the cells do not easily grow back. And with the cell loss comes so-called irreversible hearing loss.

Researchers have discovered that many people with Bardet-Biedl syndrome can't detect odors

Johns Hopkins researchers have discovered that many people with Bardet-Biedl syndrome (BBS), a rare, complex condition marked by an array of seemingly unconnected symptoms, including obesity, learning difficulties, eye problems and asthma, also have another, previously unreported problem

Effect of prebiotic and probiotic foods on health

A group of researchers at the Public University of Navarre, led by Senior Lecturer in Zoology, Elena Urdaneta Artola, have studied both the mechanisms whereby foodstuffs known as functional act at a gastrointestinal level as well as their possible beneficial effects on the health of individuals.

Sea snail offers natural healing powers for a range of illnesses from chronic pain to diseases of the brain

A beautiful, but often deadly, snail from the sea has been revealed as a largely untapped source of natural healing powers for a range of illnesses from chronic pain to diseases of the brain.

Novel pharmacological target for cannabinoid-based therapies

Cannabinoids, the active ingredients in marijuana, restrict the sprouting of blood vessels to brain tumors by inhibiting the expression of genes needed for the production of vascular endothelial growth factor (VEGF).

Ways to economically recover recombinant proteins from transgenic tobacco

The economics of producing biopharmaceuticals from transgenic plants such as tobacco is still a roadblock to producing large quantities of urgently needed medicines, especially for people in underdeveloped nations.

Research unlocks the mystery of the miraculous healing powers of honey

A Sydney researcher has unlocked the mystery of the miraculous healing powers of honey, adding to the calls for its use as a first line defence against serious infection.

New direction for research into Sly Syndrome

Findings by a Saint Louis University research team led by the scientist who discovered Sly Syndrome 32 years ago point to a new direction for research into the rare genetic disorder that can cause bone deformities, vision and hearing loss, mental retardation and death in children.
