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 3 (MAPK3) is also known as extracellular signal-regulated kinase 1 (ERK1). Transgenic gene knockout mice lacking MAPK3 are viable and it is thought that MAPK1 can fulfill some MAPK3 functions in most cells. [11] The main exception is in T cells. Mice lacking MAPK3 have reduced T cell development past the CD4 ...
A mitogen is a small bioactive protein or peptide that induces a cell to begin cell division, or enhances the rate of division . Mitogenesis is the induction (triggering) of mitosis, typically via a mitogen.
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 ...
MAPK phosphatases (MKPs) are the largest class of phosphatases involved in down-regulating Mitogen-activated protein kinases (MAPK) signaling. [1] [2] MAPK signalling pathways regulate multiple features of development and homeostasis. [3] [4] This can involve gene regulation, cell proliferation, programmed cell death and stress responses.

VEGF xxx may then cause the creation of new blood vessels in the retina and elsewhere in the eye, heralding changes that may threaten the sight. VEGF-A plays a role in the disease pathology of the wet form age-related macular degeneration (AMD), which is the leading cause of blindness for the elderly of the industrialized world. The vascular ...
In medicine these proteins are useful and are used as a mitogen to trigger T-lymphocyte cell division and to activate latent HIV-1 from human peripheral lymphocytes.In neuroscience, anterograde tracing is a research method that uses the protein product phytohaemagglutinin PHA-L as a molecular tracer that can be taken up by the cell and transported across the synapse into the next cell thereby ...
Bottom, signal enters the cell nucleus and causes transcription of DNA, which is then expressed as protein. The MAPK/ERK pathway (also known as the Ras-Raf-MEK-ERK pathway ) is a chain of proteins in the cell that communicates a signal from a receptor on the surface of the cell to the DNA in the nucleus of the cell.
