Mitogens can be either endogenous or exogenous factors. Endogenous mitogens function to control cell division is a normal and necessary part of the life cycle of multicellular organisms. For example, in zebrafish, an endogenous mitogen Nrg1 is produced in response to indications of heart damage. When it is expressed, it causes the outer layers ...
The proteins responsible for signaling the activation of satellite cells are called mitogens. A mitogen is a small protein that induces a cell to enter the cell cycle. When the cells receive signals from the neurons, it causes the myofibers to depolarize and release calcium from the sarcoplasmic reticulum.
The first mitogen-activated protein kinase to be discovered was ERK1 in mammals. Since ERK1 and its close relative ERK2 are both involved in growth factor signaling, the family was termed "mitogen-activated". With the discovery of other members, even from distant organisms (e.g. plants), it has become increasingly clear that the name is a ...
Mitochondrial biogenesis is the process by which cells increase mitochondrial numbers. [1] [2] It was first described by John Holloszy in the 1960s, when it was discovered that physical endurance training induced higher mitochondrial content levels, leading to greater glucose uptake by muscles. [3]
Mitogen-activated protein kinase kinase (also known as MAP2K, MEK, MAPKK) is a dual-specificity kinase enzyme which phosphorylates mitogen-activated protein kinase (MAPK). MAP2K is classified as EC 2.7.12.2 .
Testosterone is a hormone critical to sex drive and erectile function; low T has been found to cause ED and lower libido in some men. Again, larger studies on human populations are needed, but ...
