Study: Individuals who recovered from depression had increased level of serotonin transporter

Low levels of serotonin in the brain are seen as a possible cause of depression and many antidepressants act by blocking a protein that transports serotonin away from the nerve cells.

Supercoiling characteristic of DNA's structure controls gene expression, research shows

The two meters of -stretched- DNA contained in human cells are continuously twisting and untwisting to give access to genetic information: when a gene is expressed to generate a protein, the two strands of DNA are separated to give access to all the machinery necessary for this expression, resulting in an excessive accumulation of coiling that needs to be resolved later.

Mutant corn gene found to increase the amount of sugars in the seeds and leaves

An abnormal accumulation of carbohydrates—starches and sugars—in the kernels and leaves of a mutant line of corn can be traced back to a single misregulated gene, and this finding provides insights into how the plant responds to stress.

Researchers devise a small-molecule cocktail to protect stem cells from stress

Researchers at the National Institutes of Health (NIH) have devised a four-part small-molecule cocktail that can protect stem cells called induced pluripotent stem cells (iPSCs) from stress and maintain normal stem cell structure and function.

Plant biodiversity is sensitive to precipitation changes, shows study

Water is a scarce resource in many of the Earth's ecosystems. This scarcity is likely to increase in the course of climate change.

Researchers offer perspective on how to achieve field-scale precision irrigation

With threats of water scarcity complicating the need to feed a growing global population, it is more important than ever to get crop irrigation right.

Genetically encoded sensor helps detect hallucinogenic substances

Researchers at the University of California, Davis, have created a genetically encoded sensor for detecting hallucinogenic substances.

Increased expression of DUSP16 molecule leads to cancer chemoresistance

Chemotherapy is a drug treatment that uses powerful chemicals to kill fast-growing cancer cells in the body. It is a systemic treatment where drugs travel throughout the body and destroy cancer cells that have spread (metastasized) to parts of the body far away from the original (primary) tumour.

Study shows that autophagy plays a key role in messenger RNA degradation

Autophagy is essential in messenger RNA (mRNA) degradation, according to researchers from the Tokyo Institute of Technology (Tokyo Tech).

Critical intermediate in normal cellular metabolism may lead to cell death

A recent study shows that a critical intermediate in normal cellular metabolism is also a cause for cell death in the right sense.

SDIR1 enzyme plays a major role in the expression of defense gene in plants

A new study offers evidence that microbes are trying to hijack the plant immune system to induce disease while also offering insights into a new mechanism.

Chaperone protein imbalance initiates toxic accumulation of tau in the aging brain

Chaperone protein imbalance can play a significant role in initiating toxic accumulation of tau in the aging brain - an early step in the development of Alzheimer's disease and related neurodegenerative disorders known as tauopathies, a new preclinical study by University of South Florida Health (USF Health) neuroscientists suggests.

Study highlights the importance of autophagy in gene regulation

A fine balance between the production and degradation of biomolecules is required for optimal cell function. Autophagy is a mechanism through which cells break down and recycle their own components.

Researchers use information embedded in microbial genes as a biosensor of ocean health, productivity

Scientists from the University of California, Irvine, analyzed gains and losses in the genes of phytoplankton samples gathered from all major ocean regions to develop the most refined and highest-resolution map that shows where these photosynthetic organisms either survive or are forced to adapt to restricted amounts of main nutrients, nitrogen, iron, and phosphorus.
