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

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 process involved in cell fate commitment. Once determination has taken place, a cell becomes committed to differentiate down a particular pathway regardless of its environment.

The process in which a relatively unspecialized cell acquires the specialized features of an eye photoreceptor cell.

A vesicle-mediated transport process in which cells take up external materials or membrane constituents by the invagination of a small region of the plasma membrane to form a new membrane-bounded vesicle.

An intracellular protein kinase cascade containing at least a JNK (a MAPK), a JNKK (a MAPKK) and a JUN3K (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.

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 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 process whose specific outcome is the progression of the muscle over time, from its formation to the mature structure. The muscle is an organ consisting of a tissue made up of various elongated cells that are specialized to contract and thus to produce movement and mechanical work.

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

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.

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

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.

The process whose specific outcome is the progression of the R7 photoreceptor over time, from its formation to the mature structure. The R7 photoreceptor is the last photoreceptor to develop in the ommatidium.

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

Any process that modulates the frequency, rate or extent of hemocyte differentiation.

Any process that activates or increases the frequency, rate or extent of R7 cell differentiation.

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

Any process that stops, prevents, or reduces the frequency, rate or extent of photoreceptor cell differentiation. An example of this process is found in Drosophila melanogaster.

Any process that stops, prevents, or reduces the frequency, rate or extent of Ras protein signal transduction.

The process whose specific outcome is the progression of a neuron over time, from initial commitment of the cell to a specific fate, to the fully functional differentiated cell.

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.

The process whose specific outcome is the progression of the compound eye over time, from its formation to the mature structure. The compound eye is an organ of sight that contains multiple repeating units, often arranged hexagonally. Each unit has its own lens and photoreceptor cell(s) and can generate either a single pixelated image or multiple images, per eye.

The process in which the anatomical structures of a dendrite are generated and organized. A dendrite is a freely branching protoplasmic process of a nerve cell.

Any process that modulates the frequency, rate or extent of neurogenesis, the origin and formation of neurons.

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.

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.

That part of the nuclear content other than the chromosomes or the nucleolus.

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

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