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).

Researchers discover new role of small RNAs in Salmonella infections

Salmonella are food-borne pathogens that infect millions of people a year. To do so, these bacteria depend on a complex network of genes and gene products that allow them to sense environmental conditions.

Researchers identify novel gene mechanism in most aggressive kidney cancers

In a new study from the Johns Hopkins Kimmel Cancer Center, researchers described a novel mechanism of tumor formation in kidney cancers driven by overexpression of the mechanistic target of rapamycin complex 1 (mTORC1) signaling pathway with loss of the tuberous sclerosis complex (TSC) tumor suppressor gene.

'Epigenetic fingerprints' of prenatal alcohol exposure could be biomarkers to detect developmental disorders

Alcohol exposure in early pregnancy can change gene function during the tightly regulated embryonic development, and consequently cause developmental disorders - especially neurodevelopmental disorders.

Deep learning tool identifies mosaic mutations that cause disease

Genetic mutations cause hundreds of unsolved and untreatable disorders. Among them, DNA mutations in a small percentage of cells, called mosaic mutations, are extremely difficult to detect because they exist in a tiny percentage of the cells.

DNAm measures of biological aging linked with neuropsychologically-validated cognitive decline in midlife

A new research paper was published in Aging (listed as "Aging (Albany NY)" by MEDLINE/PubMed and "Aging-US" by Web of Science) Volume 14, Issue 23, entitled, "DNA methylation-based measures of biological aging and cognitive decline over 16-years: preliminary longitudinal findings in midlife."

Enzyme that defends human cells against viruses may be a potential target for future cancer treatments

An enzyme that defends human cells against viruses can help drive cancer evolution towards greater malignancy by causing myriad mutations in cancer cells, according to a study led by investigators at Weill Cornell Medicine.

Virus-only diet can fuel the physiological and population growth of an organism

Over a single day, in the placid waters of a single pond, a million virus particles might enter a single-celled organism known for the minuscule hairs, or cilia, that propel it through those waters.

Researchers discover a protein linked with the onset of anthracycline-associated cardiac toxicity

Anthracyclines are a class of chemotherapies effective in treating many forms of cancer, including leukemias, lymphomas and breast cancer.

Xanthan gum-based fluid thickener can lower blood glucose levels after eating, study shows

Type 2 diabetes mellitus is a common lifestyle disease that is prevalent worldwide. It can often lead to complications, such as diseases of the heart, and increased risk of death, but preventive measures, such as a healthy diet, can reduce these risks.

New software accurately infers continental ancestry from tumor DNA and RNA

Could knowing where your ancestors came from be the key to better cancer treatments? Maybe, but where would that key fit? How can we trace cancer's ancestral roots to modern-day solutions?

Cell-based method can predict how breast cancer patients will respond to treatments

Researchers at Karolinska Institutet in Sweden have developed a method that should be able to predict whether a patient with breast cancer will benefit from a particular treatment or not.

Group practice of Transcendental Meditation reduces stress in the United States, study shows

Every year during 2000 to 2006 there were tens of thousands of stress-related tragedies in the U.S. Official statistics from the FBI and Centers for Disease Control indicate that there were 15,440 murders, 93,438 rapes, and 86,348 child and adolescent deaths from accidents each year to give a few examples.
