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 blood test could predict early onset Alzheimer’s disease with high accuracy

New blood test could predict early onset Alzheimer’s disease with high accuracy

The research team previously identified that changes in the brain occur two decades before patients show signs of dementia. These changes can be detected through expensive brain imaging procedures. [More]
Landmark study provides new insight into function of enzyme related to BRCA1 protein

Landmark study provides new insight into function of enzyme related to BRCA1 protein

A landmark study to be published in the October 30, 2014 print edition of the journal Nature provides new insight into the function of an enzyme related to the BRCA1 breast-cancer protein. The study by a team at Penn State University is the first to produce a detailed working image of an enzyme in the Polycomb Repressive Complex 1 (PRC1) -- a group that regulates cell development and is associated with many types of cancer.

UCLA research could lead to simple saliva test for early diagnosis of deadly diseases

UCLA research could lead to simple saliva test for early diagnosis of deadly diseases

UCLA research could lead to a simple saliva test capable of diagnosing — at an early stage — diabetes and cancer, and perhaps neurological disorders and autoimmune diseases. [More]
Study sheds light on the mystery of biological clock that controls fertility in women

Study sheds light on the mystery of biological clock that controls fertility in women

Researchers at the University of Gothenburg have identified the biological clock that governs female fertility. The discovery represents a major contribution to research aimed at finding medical approaches to treating infertility in women. [More]
Game theory and the cancer ecosystem: an interview with Professor Pienta, Johns Hopkins

Game theory and the cancer ecosystem: an interview with Professor Pienta, Johns Hopkins

The classic description of game theory was described by the prisoner's dilemma, which is a situation in which two players have two options where the outcome depends on the simultaneous choice made by the other. [More]
Growth factor boosts natural defence against auto-immune diseases

Growth factor boosts natural defence against auto-immune diseases

Our immune system defends us from harmful bacteria and viruses, but, if left unchecked, the cells that destroy those invaders can turn on the body itself, causing auto-immune diseases like type-1 diabetes or multiple sclerosis. A molecule called insulin-like growth factor-1 (IGF-1) boosts the body's natural defence against this 'friendly fire', scientists at the European Molecular Biology Laboratory in Monterotondo, Italy, have found.

Research shows FGF21 hormone acts directly on brain to regulate obesity

Research shows FGF21 hormone acts directly on brain to regulate obesity

A hormone seen as a popular target to develop weight-loss drugs works by directly targeting the brain and triggering previously unknown activity in the nervous system, UT Southwestern Medical Center obesity researchers have found. [More]
Next generation sequencing applications automated through partnership between Beckman Coulter Life Sciences and New England Biolabs

Next generation sequencing applications automated through partnership between Beckman Coulter Life Sciences and New England Biolabs

Beckman Coulter Life Sciences, through a partnership with New England Biolabs®, Inc. (NEB®), offers automated methods to improve processes and throughput in next generation sequencing (NGS) sample preparation. Under the agreement, Beckman Coulter will use its extensive experience in automated NGS sample prep to develop, distribute and support automation for NEB’s NEBNext® sample preparation reagent kits. NEB will provide technical expertise on the reagents, chemistry and protocols. [More]
Research: MHCI protein moonlights in nervous system to regulate synapses

Research: MHCI protein moonlights in nervous system to regulate synapses

When it comes to the brain, "more is better" seems like an obvious assumption. But in the case of synapses, which are the connections between brain cells, too many or too few can both disrupt brain function. [More]
MMP-3 disrupts brain/spinal cord barrier, promotes hemorrhage

MMP-3 disrupts brain/spinal cord barrier, promotes hemorrhage

Traumatic spinal cord injury (SCI) is a devastating condition with few treatment options. Studies show that damage to the barrier separating blood from the spinal cord can contribute to the neurologic deficits that arise secondary to the initial trauma. Through a series of sophisticated experiments, researchers reporting in The American Journal of Pathology suggest that matrix metalloproteinase-3 (MMP-3) plays a pivotal role in disruption of the brain/spinal cord barrier (BSCB), cell death, and functional deficits after SCI.

Discovery offers insight on early stages of cancer

The discovery of a cellular snooze button has allowed a team of Michigan State University scientists to potentially improve biofuel production and offer insight on the early stages of cancer. [More]
MGH, MIT partner to accelerate development of diagnostic tools and therapies

MGH, MIT partner to accelerate development of diagnostic tools and therapies

A novel partnership between Massachusetts General Hospital and Massachusetts Institute of Technology is addressing three major challenges in clinical medicine – improving the diagnosis of disease, developing new approaches to prevent and treat infectious and autoimmune diseases, and developing more accurate methods of diagnosing and treating major neurodegenerative and psychiatric diseases. While individual collaborations between MGH and MIT investigators are nothing new, this formalized strategic partnership is designed to accelerate the development of diagnostic tools and therapies.

Caregivers more aware of SUDEP than patients

Caregivers more aware of SUDEP than patients

Sudden unexpected death in epilepsy (SUDEP) is concerning and many—even those with seizure disorders—may not be aware of this condition. New research published in Epilepsia, a journal published by Wiley on behalf of the International League Against Epilepsy (ILAE), reports that 76% of caregivers are more likely to have heard of SUDEP compared with 65% of patients with epilepsy.

Researchers discover new kind of stem cell that may hold clues to origins of liver cancer

Researchers discover new kind of stem cell that may hold clues to origins of liver cancer

A Mount Sinai-led research team has discovered a new kind of stem cell that can become either a liver cell or a cell that lines liver blood vessels, according to a study published today in the journal Stem Cell Reports. The existence of such a cell type contradicts current theory on how organs arise from cell layers in the embryo, and may hold clues to origins of, and future treatment for, liver cancer. [More]

Penn State scientists find that mitochondrial disease more prevalent in older moms

The discovery of a "maternal age effect" by a team of Penn State scientists that could be used to predict the accumulation of mitochondrial DNA mutations in maternal egg cells -- and the transmission of these mutations to children -- could provide valuable insights for genetic counseling. [More]
Molecular diagnostics and blood screening systems: an interview with Dr Bos and Dr Koppelman

Molecular diagnostics and blood screening systems: an interview with Dr Bos and Dr Koppelman

Screening blood donations and molecular diagnostics for patients started in the nineties. At the beginning, the level of automation in molecular diagnostic testing was limited; most of the work had to be done manually. [More]
Study can help breeders improve health-related traits in cultivated tomatoes

Study can help breeders improve health-related traits in cultivated tomatoes

Tomatoes are known to be rich in antioxidants such as vitamin C, lycopene, β-carotene, and phenolics. Antioxidants, substances capable of delaying or inhibiting oxidation processes caused by free radicals, are of interest to consumers for their health-related contributions, and to plant breeders for their ability to provide plants with natural resistance to biotic and abiotic stresses.
