Physical Reason For Shape Of Metaphase Chromosome Discovered
2014-01-15 07:37:00

Universitat Autonoma de Barcelona This work gives a solution to a fundamental question in structural biology: Why do metaphase chromosomes have their characteristic elongated cylindrical shape? The proposed solution is consistent with the structure of metaphase chromatin and with the nanomechanical properties of chromatin and chromosomes. It is a research at the interface between biology (higher order chromatin structure) and physical sciences (supramolecular structures and nanomaterials)....

Chemical Modification In Human Malaria Parasite DNA Discovered

University of California - Riverside Findings by UC Riverside researchers could help build a new drug to kill the deadly parasite that is becoming resistant to existing drugs Say "malaria" and most people think "mosquito," but the buzzing, biting insect is merely the messenger, delivering the Plasmodium parasites that sickened more than 200 million people globally in 2010 and killed about 660,000. Worse, the parasite is showing resistance to artemisinin, the most effective drug for...

McGill study suggests that a father's diet before conception plays a crucial role in the health of his offspring Mothers get all the attention. But a study led by McGill researcher Sarah Kimmins suggests that the father's diet before conception may play an equally important role in the health of their offspring. It also raises concerns about the long-term effects of current Western diets and of food insecurity. The research focused on vitamin B9, also called folate, which is found...

Study helps explain why 'survival gap' persists for African-Americans A team of scientists at Johns Hopkins and in Texas has identified a handful of genetic mutations in black Americans, in addition to some chemical alterations affecting gene activity, which may help explain why the death rate among African-Americans from the most common form of head and neck cancer continues to hover some 18 percent higher above the death rate of whites with the same cancer. The so-called survival gap...

Certain genetic alterations to the PAX gene family may be responsible for survival disparities seen between African-American and non-Latino white men with head and neck cancer, according to results presented here at the Sixth AACR Conference on the Science of Cancer Health Disparities in Racial/Ethnic Minorities and the Medically Underserved, held Dec. 6-9. "During the last 30 years, the overall five-year relative survival rates for head and neck squamous cell carcinoma (HNSCC) have...

Mindfulness Meditation Found To Result In Gene Expression Changes
2013-12-08 06:55:02

redOrbit Staff & Wire Reports – Your Universe Online While there have been multiple scientific studies providing evidence that meditation can have a positive influence on a person’s health, new research appearing in the journal Psychoneuroendocrinology suggests there may be an actual biological trigger for these therapeutic effects. Researchers from the University of Wisconsin-Madison, along with colleagues from France and Spain, report they have discovered the first evidence...

Researchers from the Bellvitge Biomedical Research Institute (IDIBELL) in Barcelona, Spain, have studied the role of a peculiar class of small non-coding RNAs that are mainly expressed in the human male germline. Whereas messenger RNAs transmit the genetic information required for protein synthesis, non-coding RNAs are functional molecules that are never translated into proteins and have important roles in diverse cellular processes. In human spermatozoa, these tiny RNAs are epigenetically...

Findings have implications for oncology, diabetes drug development Drugs that inhibit the activity of enzymes called histone deacetylases (HDACs) are being widely developed for treating cancer and other diseases, with two already on the market. Researchers at the Perelman School of Medicine, University of Pennsylvania, show that a major HDAC still functions in mice even when its enzyme activity is abolished, suggesting that the beneficial effects of HDAC inhibitors may not actually be...

Promiscuous Female Mice Have Sexier Sons
2013-11-19 07:35:02

University of Utah Males make more pheromone if mama had access to many mates University of Utah biologists found that when mother mice compete socially for mates in a promiscuous environment, their sons play hard and die young: They attract more females by making more urinary pheromones, but smelling sexier shortens their lives. "If your sons are particularly sexy, and mate more than they would otherwise, it's helping get your genes more efficiently into the next generation,"...
