Researchers discover key enzymes that are critical for sperm function

Compared to most other cells in an organism, sperm undergo a radical transformation to become compact and mobile delivery systems for paternal DNA. Even though sperm looks and moves quite differently across species, SF State researcher Diana Chu and colleagues now say that there are at least a few key enzymes that are critical for sperm development and mobility in species as different as mice and nematode worms.

Researchers shed light on inner workings of endocycle

An international team of researchers led by investigators in the U.S. and Germany has shed light on the inner workings of the endocycle, a common cell cycle that fuels growth in plants, animals and some human tissues and is responsible for generating up to half of the Earth's biomass.

First report on how patterns of 5-hmC's distribution change in mouse brain during development

In 2009, the DNA alphabet expanded. Scientists discovered that an extra letter or "sixth nucleotide" was surprisingly abundant in DNA from stem cells and brain cells.

'Deep sequencing' technology identifies new target area for depression

Scientists at the Texas Biomedical Research Institute and Yale University have identified a new target area in the human genome that appears to harbor genes with a major role in the onset of depression.

Scientists discover Leishmania parasite with juggling chromosomes

Scientists found a deadly parasite with some of its chromosomes in duplicate, others in triplicate, while still others are present four or even five times. Moreover, the copy number varies between individuals. Such a bizarre occurrence has never before been found in nature, in any organism. As a rule, chromosomes should come in couples. The scientists, from the Institute of Tropical Medicine (ITG) and the Wellcome Trust Sanger Institute, made the striking discovery while deciphering the genetic code of a series of Leishmania-parasites.

Raw fruits and veggies may offset genetic risk for heart disease: Study

In a new study a team of researchers looked at the genotypes of 27,243 people from two separate studies to see if they had a certain gene variant. Earlier studies including a 2010 meta-analysis in the Journal of the American Medical Assn. found that the 9p21 gene is associated with a higher risk of heart attack and cardiovascular disease.
