While studies in Ames dwarf mice suggest that aging and longevity are enhanced by reducing GH action, which in turn decreases total DNA methylation, the fact that these mice also lack prolactin ...

Researchers have discovered a new mechanism that is used by a male sex hormone essential for muscle and bone function. The findings could lead to the development of new drugs with fewer side effects, ...

Functional subpopulations of β-cells emerge to control pulsative insulin secretion in the pancreatic islets of mice through calcium oscillations.

Changes to the intermediate filament (IF) protein, vimentin, were found to promote tumor growth by increasing cancer stemness in an oestrogen independent manner. Targeting vimentin and/or the long ...

Progestin-only oral contraceptives prescribed or dispensed at discharge from the hospital to be started 2-3 weeks postpartum (e.g., the first Sunday after the newborn is 2 weeks old). Depot ...

Molecular evolution is the area of evolutionary biology that studies evolutionary change at the level of the DNA sequence. It includes the study of rates of sequence change, relative importance of ...

Thyroid hormones help regulate the body's metabolic rate, which is a measure of how efficient it is at using energy. When the thyroid isn’t producing enough of certain hormones, metabolism slows down; ...

Hormones are small molecules or peptides that act in signalling between one cell or cell set and another. They are generally involved in high-level processes of an organism such as growth ...
