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).

Your home is full of mold, but daycares are teeming with yeast—here’s why

Researchers found that daycares have a higher abundance of yeasts, while private houses contain more spore-producing molds, with occupant density and ventilation playing key roles in fungal distribution.

Exploring the dual role of LKB1 in tumor suppression and promotion

Mutations in serine-threonine kinase 11 (STK11) and liver kinase B1 (LKB1) are associated with disease progression in Peutz-Jeghers syndrome (PJS), which can progress to cancer.

Discovery paves way for new hepatitis B treatment

In their effort to answer a decades-old biological question about how the hepatitis B virus (HBV) is able to establish infection of liver cells, research led by Memorial Sloan Kettering Cancer Center (MSK), Weill Cornell Medicine, and The Rockefeller University identified a vulnerability that opens the door to new treatments.

Characterizing the spectrum of mitochondrial DNA deletion disease syndromes

Researchers from the Mitochondrial Medicine Program at Children's Hospital of Philadelphia (CHOP) have better characterized a spectrum of what were classically considered discrete mitochondrial DNA deletion disease syndromes.

Antioxidant-enzyme interactions and their role in non-communicable diseases

Oxidative stress, caused by an imbalance between reactive oxygen species (ROS) and antioxidant defenses, plays a central role in the development of non-communicable diseases (NCDs).

LUC7 proteins play crucial role in efficient RNA splicing

RNA splicing is a cellular process that is critical for gene expression. After genes are copied from DNA into messenger RNA, portions of the RNA that don't code for proteins, called introns, are cut out and the coding portions are spliced back together.

Genetic mutation linked to schizophrenia in both humans and mice

A genetic mutation found in two human patients with schizophrenia also increased schizophrenia-related behaviors in mice with the same mutation, a rare finding of a direct genetic link to psychosis, report researchers at the University of Illinois Urbana-Champaign and colleagues in Massachusetts and Germany.

Preventing colorectal cancer through lifestyle choices

The evidence is clear - screening for colorectal cancer may save one's life. Today, more and more people are choosing colorectal cancer screening. As a result, there is a steady decline in the number of older people getting and dying from colorectal cancer. Lower rates of smoking among Americans have also contributed to the decline in the past several years.
