The multiplication or reproduction of cells, resulting in the expansion of a cell population.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an extracellular stimulus.

The process in which a cell irreversibly increases in size over time by accretion and biosynthetic production of matter similar to that already present.

Any process that activates or increases the frequency, rate or extent of Ras protein signal transduction.

An intracellular protein kinase cascade containing at least a MAPK, a MAPKK and a MAP3K. The cascade can also contain two additional tiers: the upstream MAP4K and the downstream MAP Kinase-activated kinase (MAPKAPK). The kinases in each tier phosphorylate and activate the kinases in the downstream tier to transmit a signal within a cell.

A series of molecular signals initiated by the binding of an extracellular ligand to a receptor on the surface of the target cell where the receptor possesses tyrosine kinase activity, and ending with regulation of a downstream cellular process, e.g. transcription.

The initiation of the activity of the inactive enzyme phospolipase C as the result of a series of molecular signals generated as a consequence of a G-protein coupled receptor binding to its physiological ligand.

Any process that modulates the frequency, rate or extent of G-protein coupled receptor protein signaling pathway activity.

The multiplication or reproduction of cells, resulting in the expansion of a cell population.

Any process that results in a change in state or activity of a cell or an organism (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an extracellular stimulus.

The process in which a cell irreversibly increases in size over time by accretion and biosynthetic production of matter similar to that already present.

The process in which a cell irreversibly increases in size over time by accretion and biosynthetic production of matter similar to that already present.

The process in which a relatively unspecialized myeloid precursor cell acquires the specialized features of any cell of the myeloid leukocyte, megakaryocyte, thrombocyte, or erythrocyte lineages.

Any process that activates or increases the frequency, rate or extent of Ras protein signal transduction.

Any process that activates or increases the frequency, rate or extent of Ras protein signal transduction.

A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.

The part of the cytoplasm that does not contain organelles but which does contain other particulate matter, such as protein complexes.

The membrane surrounding a cell that separates the cell from its external environment. It consists of a phospholipid bilayer and associated proteins.

A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.

A lipid bilayer along with all the proteins and protein complexes embedded in it an attached to it.
