The directed movement of a border cell through the nurse cells to reach the oocyte. An example of this is found in Drosophila melanogaster.

The process during Drosophila embryogenesis whereby the ectodermal cells of the lateral epithelium stretch in a coordinated fashion to internalize the amnioserosa cells and close the embryo dorsally.

The process in which the R3/R4 photoreceptors commit to their cell fate. R3 and R4 are paired photoreceptors which contribute the outer rhabdomeres.

The control of viability and duration in the adult phase of the life-cycle.

The process whose specific outcome is the progression of the gonad over time, from its formation to the mature structure. The gonad is an animal organ that produces gametes; in some species it also produces hormones.

The series of molecular signals generated as a consequence of a fibroblast growth factor receptor binding to one of its physiological ligands.

The series of molecular signals generated as a consequence of a fibroblast growth factor receptor binding to one of its physiological ligands.

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 or circRNA (for protein-coding genes) and the translation of that mRNA or circRNA 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 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 or circRNA (for protein-coding genes) and the translation of that mRNA or circRNA into protein. Protein maturation is included when required to form an active form of a product from an inactive precursor form.

Any process that restricts, stops or prevents a cell from adopting a terminal cell fate in an open tracheal system. Once the terminal and fusion fates have been correctly induced, inhibitory feedback loops prevent the remaining branch cells from assuming similar fates.

Any process that restricts, stops or prevents a cell from adopting a fusion cell fate. Once the terminal and fusion fates have been correctly induced, inhibitory feedback loops prevent the remaining branch cells from assuming similar fates.

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

Any process that stops, prevents, or reduces the frequency, rate or extent of R7cell differentiation.

Any process that stops, prevents, or reduces the frequency, rate or extent of cellular DNA-templated transcription.

Any series of molecular signals initiated by the binding of an extracellular ligand to a vascular endothelial growth factor receptor (VEGFR) located on the surface of the receiving cell, and ending with regulation of a downstream cellular process, e.g. transcription.

The process whose specific outcome is the progression of the muscle fiber over time, from its formation to the mature structure. In skeletal muscle, fibers are formed by the maturation of myotubes. They can be classed as slow, intermediate/fast or fast.

Any process that modulates the frequency, rate or extent of neurogenesis, the generation of cells in the nervous system.

The process of creating protein oligomers, compounds composed of a small number, usually between three and ten, of identical component monomers. Oligomers may be formed by the polymerization of a number of monomers or the depolymerization of a large protein polymer.

The negative regulation of cell adhesion process in which an oenocyte splits off of an existing epithelial sheet.

Any process that modulates the rate, frequency or extent of the establishment of planar polarity, the coordinated organization of groups of cells in a tissue, such that they all orient to similar coordinates.

Any process that activates or increases the frequency, rate or extent of border follicle cell migration.

Any process that stops, prevents, or reduces the frequency, rate or extent of non-canonical Wnt signaling pathway.

The process whose specific outcome is the progression of sensory organs over time, from its formation to the mature structure.

The process that results in the patterns of cell differentiation that will arise in an embryo.

Any process that stops, prevents, or reduces the frequency, rate or extent of epidermal growth factor receptor signaling pathway activity.

Any process that stops, prevents, or reduces the frequency, rate or extent of epidermal growth factor receptor signaling pathway activity.

Any process that modulates the frequency, rate or extent of addition of phosphate groups into a molecule.

The directed movement of substances out of the nucleus.

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.
