HeLa cells have proven difficult to control. They sometimes contaminate other cell cultures growing in the same laboratory, interfering with ...

Hormone

... function of hormones is to serve as a signal to the target cells; the action of hormones is determined by the pattern of secretion and the signal transduction of the receiving tissue. Hormone actions vary widely, but can include stimulation or inhibition of growth, induction or suppression of apoptosis ...

Ion channel

... compression of the membrane around them; for example when their cells swell or shrink. Such channels are believed to underlie touch sensation and the transduction of acoustic vibrations into the sensation of sound. G-protein-gated channels open in response to G protein -activation via its receptor. An ...

Lac repressor
