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.

Stress hormones may silence crucial neuronal genes through specific RNA molecules

What if the brain's response to stress could be read not in fleeting neurotransmitter bursts, but in the quieting of genes deep inside chromatin? Researchers at the University of Alabama at Birmingham have now shown that stress hormones may silence crucial neuronal genes through an unexpected class of RNA molecules that operate not by encoding proteins, but by reshaping the genome's architecture.

Massive cross-ancestry study explains why obesity risks differ around the world

A massive cross-ancestry genetic study involving over 839,000 adults identified 13 genes linked to obesity, including five never before associated with the condition. The findings highlight how global genetic diversity can uncover new biological pathways and potential treatment targets for obesity.

Liver alterations associated with MASLD can directly affect the brain and behavior

A multidisciplinary research team has discovered that liver alterations associated with metabolic dysfunction-associated fatty liver disease (MASLD) can directly cause cognitive and neurological impairments, and that these effects can be reversed by a therapy exclusively targeting the liver.

Scientists capture a near-continuous molecular movie of ribosome formation

Ribosomes are the cell's protein factories, which read the genetic code and assemble the proteins that every organism needs to live. But as far as how ribosomes themselves were formed, tantalizingly little was known.

Two microbial metabolites compete to control the cells' protein building machinery

The microbiome-the trillions of bacteria, viruses, and fungi that live quietly in our body-plays a crucial role in shaping human health by providing a variety of micronutrients necessary for vital functions.

Breakthrough could offer a new therapeutic option for stopping diabetes-induced complications

Researchers from the University at Albany and NYU Grossman School of Medicine have found a way to block a key cellular pathway known to drive chronic inflammation and impaired wound healing in people with diabetes.

New study reveals how the glucocorticoid receptor forms complex structures inside cells

Drugs to treat inflammatory and autoimmune diseases - such as asthma, psoriasis, rheumatoid arthritis or Chrousos syndrome - act mainly through the glucocorticoid receptor (GR).

New drug combination shows promise in treating colorectal cancer

Colorectal cancer is one of the most common tumors among people over the age of 50. Although it is known to develop from small lesions or polyps, its exact causes are unknown — only a few risk factors are known — and it is usually treated with surgery, chemotherapy and radiotherapy, or biological therapies.

Researchers engineer a tool to dismantle cancer's RNA-built growth hubs

In a city, coworking hubs bring people and ideas together. Inside cancer cells, similar hubs form-but instead of fueling progress, they supercharge disease. That's what researchers at the Texas A&M University Health Science Center (Texas A&M Health) have discovered inside the cells of a rare and aggressive kidney cancer.
