The hydrolysis of proteins into smaller polypeptides and/or amino acids by cleavage of their peptide bonds.

Any process that modulates the surface configuration of a cell.

Any process that increases the frequency, rate or extent of gene expression. Gene expression is the process in which a gene's coding sequence is converted into a mature gene product or products (proteins or RNA). This includes the production of an RNA transcript as well as any processing to produce a mature RNA product or an mRNA (for protein-coding genes) and the translation of that mRNA into protein. Protein maturation is included when required to form an active form of a product from an inactive precursor form.

Any process that decreases the rate, frequency, or extent of epithelial to mesenchymal transition. Epithelial to mesenchymal transition where an epithelial cell loses apical/basolateral polarity, severs intercellular adhesive junctions, degrades basement membrane components and becomes a migratory mesenchymal cell.

Any process that increases the rate, frequency or extent of plasminogen activation. Plasminogen activation is the process in which plasminogen is processed to plasmin.

Any process that activates or increases the frequency, rate, extent or direction of cell growth.

The controlled breakdown of the basement membrane in the context of a normal process such as imaginal disc eversion.

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

Any process in which a host organism activates or increases the frequency, rate or extent of viral transcription, the synthesis of either RNA on a template of DNA or DNA on a template of RNA.

Any process that stops, prevents or reduces the rate or extent of epithelial cell proliferation.

The series of events involved in the perception of sound vibration in which the vibration is received and converted into a molecular signal.

A process in which a potassium ion is transported from one side of a membrane to the other.

The process in which the cochlea is generated and organized.

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 thyroid hormone stimulus.

The reflex process in which the arrectores pilorum (hair follicle) muscles contract and cause the hair to stand erect.

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

Any process that activates or increases the frequency, rate or extent of thyroid hormone generation.

All of the contents of a cell excluding the plasma membrane and nucleus, but including other subcellular structures.

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.

A cell junction that forms a connection between two or more cells in a multicellular organism; excludes direct cytoplasmic junctions such as ring canals.

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

The portion of a neuron that includes the nucleus, but excludes cell projections such as axons and dendrites.
