OBSOLETE. A developmental process that arises as an organism progresses toward the end of its lifespan that results in a decline in behavioral activities such as locomotory behavior, and learning or memory.

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 trichostatin A stimulus.

OBSOLETE. The growth of colonies in filamentous chains of cells as a result of a reduced availability of nitrogen.

The process in which a relatively unspecialized cell acquires specialized features of a tongue muscle cell.

The process in which a relatively unspecialized cell acquires specialized features of a skeletal muscle fiber cell. Skeletal muscle fiber differentiation starts with myoblast fusion and the appearance of specific cell markers (this is the cell development step). Then individual skeletal muscle fibers fuse to form bigger myotubes and start to contract.

OBSOLETE. The assembly of chromatin into senescence-associated heterochromatin foci (SAHF), transcriptionally-silent heterochromatin structures present in senescent cells, containing the condensed chromatin of one chromosome, and enriched for histone modifications. Formation of these chromatin structures is thought to repress expression of proliferation-promoting genes.

The process in which a relatively unspecialized cell acquires the specialized features of an endoderm cell, a cell of the inner of the three germ layers of the embryo.

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

Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of an antibiotic stimulus. An antibiotic is a chemical substance produced by a microorganism which has the capacity to inhibit the growth of or to kill other microorganisms.

A transcriptionally-silent heterochromatin structure present in senescent cells. Contains the condensed chromatin of one chromosome and is enriched for histone modifications. Thought to repress expression of proliferation-promoting genes.

OBSOLETE. Functions to either promote or inhibit the establishment of competence for transformation.

The series of molecular signals generated as a consequence of any member of the BMP (bone morphogenetic protein) family binding to a cell surface receptor that modulates the rate, frequency or extent of the hair cycle.

Any process that modulates the frequency, rate or extent of the cyclical phases of growth (anagen), regression (catagen), quiescence (telogen), and shedding (exogen) in the life of a hair.

OBSOLETE. Inhibits the establishment of competence for transformation.

Any process that increases the rate, frequency, or extent of meiosis I, a cell cycle process comprising the steps by which a cell progresses through the first phase of meiosis, in which cells divide and homologous chromosomes are paired and segregated from each other, producing two daughter cells.

OBSOLETE. Activates the establishment of competence for transformation.

The developmental process pertaining to the initial formation of a camera-type eye from unspecified neurectoderm. This process begins with the differentiation of cells that form the optic field and ends when the optic cup has attained its shape.

The series of molecular signals initiated by binding of a Wnt protein to a frizzled family receptor on the surface of the target cell, followed by propagation of the signal via beta-catenin, and ending with a change in transcription of target genes that modulates the rate, frequency or extent of the hair cycle.

Binding to a phosphorylated amino acid residue within a protein.
