Ribonucleic acid (RNA) is a biologically important type of molecule that consists of a long chain of nucleotide units. Each nucleotide consists of a nitrogenous base, a ribose sugar, and a phosphate.

LMO1 gene variation can increase neuroblastoma risk

Pediatric cancer researchers have identified variations in a gene as important contributors to neuroblastoma, the most common solid cancer of early childhood. The study team, led by researchers at The Children's Hospital of Philadelphia, found that common variants in the LMO1 gene increase the risk of developing an aggressive form of neuroblastoma, and also mark the gene for continuing to drive the cancer's progression once it forms.

Diabetes plays a vital role in regulating brain cholesterol: Research

The brain contains more cholesterol than any other organ in the body, has to produce its own cholesterol and won't function normally if it doesn't churn out enough. Defects in cholesterol metabolism have been linked with Alzheimer's disease and other neurodegenerative conditions. Now researchers at Joslin Diabetes Center have discovered that diabetes can affect how much cholesterol the brain can make.

Researchers reveal ultra-fast processes of DNA photostability

The genetic material of DNA contains shielding mechanisms to protect itself from the exposure to the UV light emitted by the sun. This is of crucial importance, since without photostability i.e. without programmed defense mechanisms against UV irradiation a rapid degradation of DNA and RNA would be the consequence. As part of a project funded by the Austrian Science Fund (FWF) a group of researchers led by Hans Lischka, Quantum Chemist of the University of Vienna, Austria, could, for the first time, comprehensively unravel these ultra-fast processes of the photostability of the nucleobases.

How HIV kills CD4 T cells

Researchers appear to have an explanation for a longstanding question in HIV biology: how it is that the virus kills so many CD4 T cells, despite the fact that most of them appear to be "bystander" cells that are themselves not productively infected. That loss of CD4 T cells marks the progression from HIV infection to full-blown AIDS, explain the researchers who report their findings in studies of human tonsils and spleens in the November 24th issue of Cell, a Cell Press publication.
