DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).

Subtle mutation affecting epigenome may lead to inherited form of mental retardation: Researchers

A subtle mutation affecting the epigenome –- a set of dynamic factors that influence gene activity -- may lead to an inherited form of mental retardation that affects boys, find researchers at Children's Hospital Boston. The disorder, which also involves cleft lip or cleft palate, appears to hinge on an enzyme working in a biological pathway that may offer several potential drug targets.

Study: Small fragment of RNA appears to protect rats against cocaine addiction

A specific and remarkably small fragment of RNA appears to protect rats against cocaine addiction-and may also protect humans, according to a recent study funded by the National Institute on Drug Abuse (NIDA), a component of the National Institutes of Health. The study was published today in the journal Nature.

HPV DNA testing for precancer, cervical cancer is more sensitive than cytology testing: Study

HPV DNA testing for precancers and cervical cancers is over 50 per cent more sensitive than cytology testing for the same conditions a community-based study in Mexico has revealed. Results of the largest HPV DNA primary screening study ever to be performed in a Latin American country point to the readiness of HPV DNA testing for large-scale implementation in Mexico and are published online today (8 July 2010) in Cancer, Causes and Controls.

Screening for HPV genotypes 16 and 18 helps detect cervical pre-cancer missed by Pap test

Roche today announced that data from the ATHENA (Addressing THE Need for Advanced HPV Diagnostics) U.S. registration trial of over 47,000 women demonstrate that two human papillomavirus genotypes, HPV 16 and HPV 18, can identify those women with cervical pre-cancer missed by cytologic examination with a Papanicolau (Pap) test.

Research findings may help scientists understand how muscle and heart diseases develop

Researchers from Mount Sinai School of Medicine have identified a previously unknown mechanism by which cells direct gene expression, the process by which information from a gene is used to direct the physical and behavioral development of individuals. The research, which may help scientists gain insight into how muscle and heart diseases develop, is published in the July 8th issue of Nature.

Researchers report how mature red blood cells form

We take our blood for granted, but its creation requires a complicated series of steps, starting with the formation of blood stem cells during early embryonic development, followed by progressive differentiation into the progenitors of red cells, white cells and platelets, and ultimately the full set of blood cells.

Student-led team awarded top honor in 2010 CIMIT Prize in Primary Healthcare competition

Imagine finding out before you leave the pediatrician's office if your child has strep throat, or even something more serious requiring a different treatment. A novel application for applying DNA "nanobarcodes" in a clinical assay could help primary-care physicians quickly and more accurately determine what's causing a patient's acute pharyngitis from an easy throat swab.
