Steroid binding to metabolic enzyme

The human cytochrome P450 enzymes are responsible for metabolizing a variety of substances—from lipids (fats) and steroid hormones to drugs and toxic chemicals.

Penis development needs more than just testes and testosterone

Proper development of the fetal penis requires not just testosterone from the testes, but a second hormone produced by other tissues, including the placenta, according to a new study publishing February 14 in the open-access ...

Rewriting the textbook on how steroid hormones enter cells

A discovery by scientists at UC Riverside may open up new ways to control steroid hormone-mediated processes, including growth and development in insects, and sexual maturation, immunity, and cancer progression in humans.

How insects decide to grow up

Like humans, insects go through puberty. The process is known as metamorphosis. Examples include caterpillars turning into butterflies and maggots turning into flies.

Defying frost and the cold with hormones

Plants cannot simply relocate to better surroundings when their environmental conditions are no longer suitable. Instead, they have developed sophisticated molecular adaptation mechanisms. Scientists at the Technical University ...

Uncovering pathway that makes steroid hormones fast and efficient

How can the group of chemicals known as steroid hormones cause almost instantaneous changes in your body, like hydrocortisone inhalers with asthma? In an interview with UC Science Today, UC Berkeley researcher Polina Lishko ...
