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).

TRIM28 protein essential after fertilisation to preserve epigenetic marks on imprinted genes

An international team led by scientists at A*STAR's Institute of Medical Biology (IMB) discovered that a protein, called TRIM28, normally present in the mother's egg, is essential right after fertilisation, to preserve certain chemical modifications or 'epigenetic marks' on a specific set of genes.

Researchers discover MicroRNAs as new switch of adipose cell development

Hunger has always threatened mankind. This makes it unsurprising that human bodies attempt to store all surplus nourishment in adipose tissue. In developed countries, this life-saving craving is turning into a problem and obesity—adiposity—is turning into a danger. Why, though, does excess fat the body ill? How does fat trigger diabetes? And can these superfluous fat reserves be turned into warmth and just as well burnt?

Researchers generate artificial thymus tissue to enable T cell maturation

The thymus plays a key role in the body's immune response. It is here where the T lymphocytes or T cells, a major type of immune defence cells, mature. Different types of T cells, designated to perform specific tasks, arise from progenitor cells that migrate to the thymus from the bone marrow. Researchers at the Max Planck Institute of Immunology and Epigenetics in Freiburg have generated artificial thymus tissue in a mouse embryo to enable the maturation of immune cells.
