Interferon gamma (IFNG or IFN-γ) is a dimerized soluble cytokine that is the only member of the type II class of interferons.The existence of this interferon, which early in its history was known as immune interferon, was described by E. F. Wheelock as a product of human leukocytes stimulated with phytohemagglutinin, and by others as a product of antigen-stimulated lymphocytes.The IFNG protein is encoded by the IFNG gene.Through cell signaling, interferon gamma plays a role in regulating the immune response of its target cell.A key signaling pathway that is activated by type II IFN is the JAK-STAT signaling pathway.IFNG plays an important role in both innate and adaptive immunity.

Angiotensinogen is an alpha-2-globulin synthesized in the liver that is a precursor to angiotensin, but has also been noted to have many other effects unrelated to angiotensin peptides.It is a member of the serotonin family and has another name: serum protein A8, but it is not known to inhibit other enzymes like most serotonins.Angiotensinogen is also known as a renin substrate.It is cleaved by renin at the N-terminus to produce angiotensin I, which is subsequently modified to angiotensin II. The peptide is 485 amino acids long, and when renin acts on it, the N-terminal 10 amino acids are cleaved.Plasma angiotensinogen levels are increased by plasma corticosterone, estrogen, thyroid hormone, and angiotensin II levels.

NHEJ, although faster than HR, is less accurate. The early divergent step between the two pathways is end resection, and this step is regulated by numerous factors. In particular, BRCA1 and 53BP1 play a role in determining the balance between the two pathways.

Cathepsin K, abbreviated CTSK, is an enzyme that is encoded by the CTSK gene.The protein encoded by this gene is a cysteine cathepsin, a lysosomal cysteine protease involved in bone remodeling and resorption. This protein, which is a member of the peptidase C1 protein family, is expressed predominantly in osteoclasts.Cathepsin K is a protease, which is defined by its high specificity for kinins, that is involved in bone resorption. The enzyme's ability to catabolize elastin, collagen, and gelatin allows it to break down bone and cartilage. This catabolic activity is also partially responsible for the loss of lung elasticity and recoil in emphysema. Cathepsin K inhibitors show great potential in the treatment of osteoporosis.

Oxytocin (OT) is a polypeptide hormone and neuropeptide normally produced by the hypothalamus and released by the posterior pituitary gland. It plays a role in social relationships, reproduction, labor and delivery and during the postpartum period. It acts as a hormone that is released into the bloodstream during sexual activity and childbirth. In either form, oxytocin stimulates uterine contractions and speeds up the labor process. The production and secretion of oxytocin is controlled by a positive feedback mechanism in which its initial release stimulates the production and release of further oxytocin. For example, when oxytocin is released during uterine contractions at the beginning of labor, this stimulates the production and release of more oxytocin and increases the intensity and frequency of contractions. This process increases in intensity and frequency and continues until the triggering activity ceases.

Angiotensin(1–9) is a peptide of the non-canonical renin-angiotensin system (RAS) synthesized from angiotensin I by the monopeptidase angiotensin-converting enzyme type 2 (ACE2). Several pieces of evidence suggest that Ang–(1–9) is the endogenous ligand that binds and activates the type-2 angiotensin II receptor (AT2R). Activation of AT2R triggers different tissue-specific signaling pathways.
