Exposure to the chemical BPA (Bisphenol A) stimulates prostate cancer cell growth

An estrogen-like chemical commonly used to synthesize plastic food containers has been shown to encourage the growth of a specific category of prostate cancer cell, potentially affecting the treatment efficacy for a subset of prostate cancers.

Discovery shows how embryonic stem cells perform 'quality control' inspections

Biologists at the University of California, San Diego have found a fundamental mechanism used by embryonic stem cells to assure that genetically damaged stem cells do not divide and pass along the damage to daughter stem cells.

Turning off cell suicide switch fails to stop prion damage

Researchers knew that prions, the misfolded proteins that cause mad cow disease and other brain disorders, were killing off a class of important brain cells in a transgenic mouse model. But when they found a way to rescue those cells, they were astonished to discover the mice still became sick.

Stem cells use inflammatory signals to find injured tissue

A joint effort led by stem cell biologist Evan Y. Snyder, M.D., Ph.D., of The Burnham Institute, and Samia J. Khoury, M.D., of Harvard Medical School and Brigham and Women’s Hospital, report data suggesting that stem cells use inflammatory signals to “know” where they must home.

Newly discovered genetic defect might represent an important risk factor for major depression

A newly discovered genetic defect might represent an important risk factor for major depression, a condition which effects 20 million people in the U.S., according to Duke University Medical Center researchers.

New research is allowing biochemists to understand a key hierarchy of protein interactions that occurs in DNA

"All cancers are marked by some form of DNA replication gone awry, so a basic understanding of DNA replication is of paramount importance to those designing cancer-fighting drugs,"

Study on methylisothiazolinone in shampoo lacks a credible scientific basis

Consumers can rest assured that their cosmetic products, including shampoos, are safe. The abstract on Methylisothiazolinone (MI), presented at the Cell Biology 2004 meeting of the American Society for Cell Biology, lacks a credible scientific basis in suggesting that MI could be a safety issue for consumers using personal care products.

Common ingredient in some shampoos (methylisothiazolinone) stunts developing neurons of rats

An antimicrobial agent found in some shampoos and hand creams and widely used in industrial settings inhibits the development of particular neuron structures that are essential for transmitting signals between cells.

As mobile phone use rises, possibility of unseen biological impact is quietly troubling

Cell biologists are of two minds about the possible biological effects of mobile phone radiation. In the mid-1990s, studies describing possible pathological effects on tissues bombarded with low-level radio frequencies (RF) were first featured in the popular press and then discredited by scientists.

Scientists have given blind nerve cells the ability to detect light

Scientists at the University of California, Berkeley, have given "blind" nerve cells the ability to detect light, paving the way for an innovative therapy that could restore sight to those who have lost it through disease.

Generic antipsychotic drugs can protect brain cells from progressive multifocal leukoencephalopathy

Generic antipsychotic drugs can protect brain cells from a virus that causes a fatal nervous system disorder, according to research conducted at Brown University and Case Western Reserve University.

Acetaminophen shows positive cardioprotective effects In heart attack, arrhythmia

Long an under-studied yet widely-used over-the-counter medication, acetaminophen over the last few years is becoming recognized for a range of potential therapeutic uses beyond headache and pain.

Researchers attempt to quantify processes underlying cell heterogeneity

Combining the latest methods in gene splicing and computer modeling, Rice University researchers are trying to develop a predictive framework for one of the most basic and complex biological phenomena — cellular heterogeneity, or the ability of genetic clones to act and behave differently when exposed to the same set of environmental stimuli.

Gene regulated by need to process proteins linked to enlargement of protein processing factory

Part of a cellular mechanism that regulates the folding of new proteins into their proper shapes also includes a genetic response that enlarges the factory where both protein folding and packaging of proteins occurs.

New role for a key protein involved in muscle contraction

Overturning a scientific stereotype, researchers at the University of Illinois at Chicago have discovered a new role for a key protein involved in muscle contraction and shown it is present not just in the cytoplasm of cells but in the nucleus as well.

Discovery affirms potential of stem cells for the development of possible therapies for spinal cord injury and nervous system disorders

Researchers at The Hospital for Sick Children (Sick Kids) have shown that stem cells found in adult skin retain their embryonic capability of making many types of cells.

Lead exposure can hinder recovery from a brain injury

Lead exposure at a young age can hurt the brain's development and cause learning and behavioral problems. It may also interfere with recovery from a brain injury.

Potential new treatment strategy against metastatic cancer cells

A team of scientists at The Scripps Research Institute has identified a potential treatment strategy against metastatic cancer cells that has never been tried before.

High levels of a protein called LRP6 can make cancer cells more aggressive

The protein's ability to enhance tumor development suggests that the gene that codes for LRP6 is an oncogene--a gene that contributes to tumor development when overactivated.

Key discovery toward understanding mechanism associated with uncontrollable muscular movements

Neurodegenerative diseases such as Alzheimer's, Parkinson's, Lou Gehrig's and Huntington's exhibit loss of nerve function in different ways, from memory lapses to uncontrollable muscular movements, but it is now believed that these diseases share many common molecular mechanisms.
