Any process that decreases the frequency, rate or extent of poly(A) tail shortening of a nuclear-transcribed mRNA. Poly(A) tail shortening is the decrease in length of the poly(A) tail of an mRNA from full length to an oligo(A) length.

Any process that modulates the frequency, rate or extent of poly(A) tail shortening of a nuclear-transcribed mRNA. Poly(A) tail shortening is the decrease in length of the poly(A) tail of an mRNA from full length to an oligo(A) length.

Any process that stops, prevents or reduces the frequency, rate or extent of nuclear-transcribed mRNA catabolic process, deadenylation-dependent decay.

The series of molecular signals initiated by the binding of glutamate to its receptor on the surface of a target cell, and ending with the regulation of a downstream cellular process, e.g. transcription.

Any process that increases the frequency, rate or extent of poly(A) tail shortening of a nuclear-transcribed mRNA. Poly(A) tail shortening is the decrease in length of the poly(A) tail of an mRNA from full length to an oligo(A) length.

The directed movement of a germ cell from their site of production to the gonad, through the attraction of cells towards their target.

The estrous cycle phase in which there is subsiding follicular function.

The directed movement of a germ cell from their site of production to the gonad, through the repulsion of cells away from a tissue.

The chemical reactions and pathways resulting in the formation of any of the vitamin A compounds, retinol, retinal (retinaldehyde) and retinoic acid. Animals cannot synthesize vitamin A de novo, but form it through oxidative cleavage of carotenoids.

The chemical reactions and pathways involving any of the vitamin A compounds, retinol, retinal (retinaldehyde) and retinoic acid, all of which are derivatives of beta-carotene.

A second wave of blood cell production that, in vertebrates, generates long-term hemopoietic stem cells that continously provide erythroid, myeloid and lymphoid lineages throughout adulthood.

The process in which a relatively unspecialized cell acquires the characteristics of a mature hemangioblast. Hemangioblasts are the proposed common precursor of blood and endothelial lineages.

Combining with the neuropeptide proctolin, to initiate a change in cell activity.

Formation of the endocardium of the heart. The endocardium is an anatomical structure comprised of an endothelium and an extracellular matrix that forms the innermost layer of tissue of the heart, and lines the heart chambers.

Combining with the neuropeptide corazonin to initiate a change in cell activity.

A first transient wave of blood cell production that, in vertebrates, gives rise to erythrocytes (red blood cells) and myeloid cells.

The stages of blood cell formation that take place within the embryo.

The operation of the mind by which an organism becomes aware of objects of thought or perception; it includes the mental activities associated with thinking, learning, and memory.

Any process involved in the maintenance of an internal steady state of water within a tissue, organ, or a multicellular organism.

The process in which a relatively unspecialized cell acquires specialized features of a hematopoietic stem cell. A stem cell is a cell that retains the ability to divide and proliferate throughout life to provide progenitor cells that can differentiate into specialized cells.
