The initiation of the activity of the inactive enzyme MAP kinase (MAPK).

Any process that activates or increases the frequency, rate or extent of EGF-activated receptor activity.

Any process that activates or increases the frequency, rate or extent of mitosis.

Any process that activates or increases the rate or extent of epithelial cell proliferation.

The multiplication or reproduction of hepatocytes, resulting in the expansion of a cell population. Hepatocytes form the main structural component of the liver. They are specialized epithelial cells that are organized into interconnected plates called lobules.

The initiation of the activity of the inactive enzyme MAP kinase (MAPK).

The initiation of the activity of the inactive enzyme MAP kinase (MAPK).

Blood vessel formation when new vessels emerge from the proliferation of pre-existing blood vessels.

Any process that modulates the frequency, rate or extent of transcription from an RNA polymerase II promoter.

The directed movement of substances from the endoplasmic reticulum (ER) to the Golgi, mediated by COP II vesicles. Small COP II coated vesicles form from the ER and then fuse directly with the cis-Golgi. Larger structures are transported along microtubules to the cis-Golgi.

A series of molecular signals initiated by binding of a ligand to the tyrosine kinase receptor EGFR (ERBB1) on the surface of a cell. The pathway ends with regulation of a downstream cellular process, e.g. transcription.

Any process that activates or increases the rate or extent of cell proliferation.

Any process that activates or increases the rate or extent of cell proliferation.

The series of events that restore integrity to a damaged tissue, following an injury.

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 a drug stimulus. A drug is a substance used in the diagnosis, treatment or prevention of a disease.

Any process that stops, prevents, or reduces the frequency, rate or extent of cell death by apoptotic process.

Any process that activates or increases the frequency, rate or extent of EGF-activated receptor activity.

Any process that activates or increases the frequency, rate or extent of EGF-activated receptor activity.

Any process that activates or increases the frequency, rate or extent of mitosis.

Any process that activates or increases the frequency, rate or extent of mitosis.

The addition of COPII proteins and adaptor proteins to ER membranes during the formation of transport vesicles, forming a vesicle coat.

Any process that stops, prevents, or reduces the frequency, rate or extent of a cellular process, any of those that are carried out at the cellular level, but are not necessarily restricted to a single cell. For example, cell communication occurs among more than one cell, but occurs at the cellular level.

Any process that activates or increases the rate or extent of epithelial cell proliferation.

Any process that activates or increases the rate or extent of epithelial cell proliferation.

Any process that activates or increases the frequency, rate or extent of the phosphorylation of peptidyl-tyrosine.

The progression of the mammary gland alveolus over time, from its formation to its mature state. The mammary gland alveolus is a sac-like structure that is found in the mature gland.

That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid.

That part of a multicellular organism outside the cells proper, usually taken to be outside the plasma membranes, and occupied by fluid.

A membrane-bounded organelle of eukaryotic cells in which chromosomes are housed and replicated. In most cells, the nucleus contains all of the cell's chromosomes except the organellar chromosomes, and is the site of RNA synthesis and processing. In some species, or in specialized cell types, RNA metabolism or DNA replication may be absent.

The lipid bilayer surrounding the endoplasmic reticulum.

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

The component of the plasma membrane consisting of the gene products and protein complexes having at least some part of their peptide sequence embedded in the hydrophobic region of the membrane.

The external part of the cell wall and/or plasma membrane.

The external part of the cell wall and/or plasma membrane.

The lipid bilayer surrounding a vesicle transporting substances from the endoplasmic reticulum to the Golgi.

The region of the plasma membrane that includes the basal end and sides of the cell. Often used in reference to animal polarized epithelial membranes, where the basal membrane is the part attached to the extracellular matrix, or in plant cells, where the basal membrane is defined with respect to the zygotic axis.

A vesicle found in the cytoplasm of a cell.

A vesicle found in the cytoplasm of a cell.

The lipid bilayer surrounding any of the compartments of the endoplasmic reticulum (ER)-Golgi intermediate compartment system.

Cytoplasm situated near, or occurring around, the nucleus.
