Function of stem cells in blood-forming system is regulated by estrogen, says study

Scientists have known for years that stem cells in male and female sexual organs are regulated differently by their respective hormones. In a surprising discovery, researchers at the Children's Medical Center Research Institute at UT Southwestern (CRI) and Baylor College of Medicine have found that stem cells in the blood-forming system — which is similar in both sexes — also are regulated differently by hormones, with estrogen proving to be an especially prolific promoter of stem cell self-renewal.

Exposing adolescent to marijuana can lead to behavioral alterations in next generation

Exposing adolescent rats to THC (tetrahydrocannabinol) -the primary psychoactive ingredient in marijuana—can lead to molecular and behavioral alterations in the next generation of offspring, even though progeny were not directly exposed to the drug, researchers at the Icahn School of Medicine at Mount Sinai have found.

Gender differences in memory

If your husband is absent-minded, forgets your wedding anniversary or the name of your new neighbor, don't worry. You are not the only one with a forgetful man in the house. Even researchers were surprised by how much men forget.

Hydroxytyrosol in olive oil may help reduce risk of breast cancer

A major component of olive oil, hydroxytyrosol, is the subject of a Houston Methodist study of women who are at increased risk of developing breast cancer. The study focuses on the changes in breast density after one year of treatment and is the first of its kind in the United States.

Scientists develop new genetic platform that yields novel antibiotic from ocean bacteria

Scientists at the University of California, San Diego have developed a new genetic platform that allows efficient production of naturally occurring molecules, and have used it to produce a novel antibiotic compound.

Researchers find that 20% of women with ovarian cancer had inherited mutations in gene pathway

A new study conservatively estimates that one in five women with ovarian cancer has inherited genetic mutations that increase the risk of the disease, according to research at Washington University School of Medicine in St. Louis.

Researchers examine how neurons in brain control arm movements

Sometimes that's how our brains work. When we anticipate a physical act, such as reaching for the keys we noticed on the table, the neurons that control the task adopt a state of readiness, like sprinters bent into a crouch.

Jackson Laboratory collaborates with Seoul National University to develop new mouse models, tumor repository

The Jackson Laboratory, in collaboration with Seoul National University, will receive a five-year, $7.5 million grant from the South Korean government for a large-scale cancer genomics project employing the latest sequencing technology and special JAX mouse models that can host human tumors.

Chinese and American researchers introduce new approach to gene therapy

Resistance of tumor cells toward multiple cytostatic drugs is a serious problem in cancer treatment. In the journal Angewandte Chemie, a team of Chinese and American researchers has now introduced a new approach to gene therapy that could counter this problem: The gene that codes for resistance is “silenced” through the use of an ingenious nanocomplex.

Lack of SIRT1 protein in the liver leads to lower levels of liver FGF21

A new study led by Boston University School of Medicine demonstrates that the abnormal metabolism linked to obesity could be regulated in part by the interaction of two metabolic regulators, called the NAD-dependent deacetylase SIRT1 and fibroblast growth factor 21 (FGF21). Using experimental models, the researchers found that a lack of SIRT1 protein in the liver led to lower levels of a liver secreted protein FGF21, which resulted in an increased likelihood of developing fatty liver disease and obesity.

High-protein diet increases chance of developing kidney stones, other renal diseases

High-protein diets, like the popular Dr. Dukan diet, increase the long-term risk of developing kidney disease and have a negative effect on renal urinary and morphological markers. What's more, they may promote serious pathologies like nephrolithiasis (calcium kidney stones) because they drastically reduce urinary citrate (an inhibitor of calcium salt crystallization) and urinary pH, and increase urinary calcium (to compensate for the metabolic acidity caused by excess protein).

Xpert MTB/RIF test quickly detects TB and resistance to rifampicin

A second systematic review of a diagnostic test for tuberculosis (TB) endorsed by the World Health Organisation (WHO), has confirmed the accuracy of the test. The updated review assessing the accuracy of Xpert MTB/RIF includes new studies published since the original Cochrane Review was published in January last year.

Scientists identify specific enzyme essential for brain development

Scientists from the Max F. Perutz Laboratories (MFPL) of the University of Vienna and the Medical University of Vienna have identified a specific enzyme, histone deacetylase 2 (HDAC2), as essential for brain development. The findings published in Development are important to advance the development of new drugs to treat neurological diseases.

Self-testing for HPV effective in detecting cervical cancer

Self-testing for Human Papillomavirus (HPV) - the virus that causes cervical cancer - is as effective at detecting cancer as a conventional smear test (cytology screening) even when scaled up to test large populations.

People who are less patient tend to move eyes with greater speed, say researchers

Using a simple study of eye movements, Johns Hopkins scientists report evidence that people who are less patient tend to move their eyes with greater speed. The findings, the researchers say, suggest that the weight people give to the passage of time may be a trait consistently used throughout their brains, affecting the speed with which they make movements, as well as the way they make certain decisions.

Researchers demonstrate existence of an epigenetic lesion in hippocampus of Alzheimer patients

Alzheimer's disease can reach epidemic range in the coming decades, by the increasing average age of society. There are two key issues for Alzheimer's disease: there is currently no effective treatment and it has been described very few associated genetic changes (mutations) which reduces the number of targets for future therapies.
