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).

Scientists discover repair mechanism of photolyase in sun damaged DNA

Researchers have long known that humans lack a key enzyme one possessed by most of the animal kingdom and even plants that reverses severe sun damage.For the first time, researchers have witnessed how this enzyme works at the atomic level to repair sun-damaged DNA.The discovery holds promise for future sunburn remedies and skin cancer prevention.

New biophotonic imaging method monitors transformations of cellular macromolecules during apoptosis in real-time

Apoptosis, programmed cell death, is essential to normal development, healthy immune system function, and cancer prevention. The process dramatically transforms cellular structures but the limitations of conventional microscopy methods have kept much about this structural reorganization a mystery.

Circulating aberrant cells increase as non-small cell lung cancer progresses

A novel approach detects genetically abnormal cells in the blood of non-small cell lung cancer patients that match abnormalities found in tumor cells and increase in number with the severity of the disease, a research team led by scientists at The University of Texas MD Anderson Cancer Center report in the journal Clinical Cancer Research.

Repetition of DRD4 genotype may increase risk for extensive alcohol use

Your friend walks into a bar to meet you for happy hour. He sidles up to the bar and orders a drink - does that make you more likely to get a drink yourself? According to new findings reported in Psychological Science, a journal of the Association for Psychological Science, genetics may determine the extent to which you are influenced by social drinking cues - signals such as advertisements, drinks placed on a bar, and seeing other people around you drinking.

Bullied children are at risk for developing emotional problems

Bullying victimization is common among children of school age, although its consequences are often anything but benign. The recent death of a Massachusetts teen by suicide prompted state lawmakers to pass one of the most far-reaching anti-bullying laws within the U.S. Whether such legislative actions result in measurable decreases in physical or emotional distress among school peers remains to be seen.

Gene expression profiling may provide molecular diagnostic tool to diagnose depression

Blood tests have been extremely important tools aiding doctors in making medical diagnoses and in guiding the treatment of many diseases. However, psychiatry is one area of medicine where there are few diagnostic blood tests.New scientific fields may someday generate blood tests that can be used for these purposes. Some of the areas under increasingly intensive study are genetics, the study of variations in the genes that can be extracted from blood cells, and genomics like proteomics, the measurement of the levels of specific proteins in the blood, and gene expression profiling, which measures the levels of RNA produced from DNA as an indication of the level of the "activity" of particular genes.

Genomics researchers study role of protein in metabolic disorders, heart disease

Studying a protein already known to play an important role in type 2 diabetes and cancer, genomics researchers have discovered that it may have an even broader role in disease, particularly in other metabolic disorders and heart disease. In finding unsuspected links to other disease-related genes, the scientists may have identified future targets for drug treatments.

New research identifies stem cells that generate three critical classes of nerve cells

New research, published in the journal Development, by Dr. Anthony-Samuel LaMantia, professor of Pharmacology & Physiology and director of the newly formed GW Institute for Neuroscience, and his colleagues have identified the stem cells that generate three critical classes of nerve cells - olfactory receptors, vomeronasal and gonadotropin releasing hormone neurons - that are responsible for enabling animals and humans, to eat, interact socially and reproduce.
