WKP
Definition : Gaseous signaling molecules are gaseous molecules that are either synthesised internally (endogenously) in the organism, tissue or cell or are received by the organism, tissue or cell from outside (say, from the atmosphere or hydrosphere, as in the case of oxygen) and that are used to transmit chemical signals which induce certain physiological or biochemical changes in the organism, tissue or cell.
The term is applied to, for example, oxygen, carbon dioxide, nitric (...)

HSD3B1
21 February 2020WKP
Definition: HSD3B1 is a human gene that encodes for a 3beta-hydroxysteroid dehydrogenase/delta(5)-delta(4)isomerase type I or hydroxy-delta-5-steroid dehydrogenase, 3 beta- and steroid delta-isomerase 1.
While it can carry out the same function as HSD3B2, it localizes primarily to different tissues, such as the placenta and nonsteroidogenic tissues.
Its requirement for the production of progesterone by the placenta, which has a vital role in pregnancy, may be one reason why no (...) -
contractile proteins
9 January 2020Contractile proteins in phagocytosis
By applying force to actin filaments, the plasma membrane, and intracellular proteins and organelles, myosins can generate contractility, directly regulate actin assembly to ensure proper phagocytic internalization, and translocate phagosomes or other cargo to appropriate cellular locations. Altering the actomyosin cytoskeleton affects phagocytic behavior.

PLIN2
14 December 2019WKP
Definition : Adipose differentiation-related protein, also known as perilipin 2 , ADRP or adipophilin, is a protein which belongs from PAT family of cytoplasmic lipid droplet (CLD) binding protein.
In humans it is encoded by the ADFP gene. This protein surrounds the lipid droplet along with phospholipids and are involved in assisting the storage of neutral lipids within the lipid droplets.

FOSs
12 December 2019The Fos gene family ( FOSs ) consists of 4 members: c-Fos , FOSB , FOSL1 , and FOSL2. These genes encode leucine zipper proteins that can dimerize with proteins of the JUN family, thereby forming the transcription factor complex AP-1. As such, the FOS proteins have been implicated as regulators of cell proliferation, differentiation, and transformation.

genetic recombination
11 November 2019WKP
Genetic recombination (also known as genetic reshuffling) is the exchange of genetic material between different organisms which leads to production of offspring with combinations of traits that differ from those found in either parent.
In eukaryotes, genetic recombination during meiosis can lead to a novel set of genetic information that can be passed on from the parents to the offspring. Most recombination is naturally (...) -
mutational signatures
10 November 2019WKP
Examples : ultraviolet mutational signature
Definition : Mutational signatures are characteristic combinations of mutation types arising from specific mutagenesis processes such as DNA replication infidelity, exogenous and endogenous genotoxins exposures, defective DNA repair pathways and DNA enzymatic editing.
Deciphering mutational signatures in cancer provides insight into the biological mechanisms involved in carcinogenesis and normal somatic mutagenesis.
