What is Kinetin?

Kinetin is a kind of cytokinin, a class of plant hormone that promotes cell division. Kinetin was originally isolated by Miller and Skoog et al. as a compound from autoclaved herring sperm DNA that had cell division-promoting activity. It was given the name kinetin because of its ability to induce cell division, provided that auxin was present in the medium. The story of the discovery of kinetin is a fascinating example of the twists and turns of scientific discovery. Kinetin is often used in plant tissue culture for inducing formation of callus (in conjunction with auxin) and to regenerate shoot tissues from callus (with lower auxin concentration).
For a long time, it was believed that kinetin was an artifact produced from the deoxyadenosine residues in DNA, which degrade on standing for long periods or when heated during the isolation procedure. Therefore, it was thought that kinetin does not occur naturally, but, since 1996, it has been shown by several researchers that kinetin exists naturally in the DNA of cells of almost all organisms tested so far, including human and various plants. The mechanism of production of kinetin in DNA is thought to be via the production of furfural — an oxidative damage product of deoxyribose sugar in DNA — and its quenching by the adenine base's converting it into N6-furfuryladenine, kinetin.
Since 1994, Kinetin has been thoroughly tested for its powerful anti-aging effects in human skin cells and other systems. At present, kinetin is one of the widely used components in numerous skin care cosmetics and cosmeceuticals, such as Valeant products kinerase . There are some reports published on other biological effects of kinetin in human beings, for example its effects as anti-platelet aggregation factor reducing thrombosis formation. In addition, it has been shown to be capable of correcting RNA mis-splicing in the disease of familial dysautonomia, in which exon 20 of IKBKAP is skipped instead of included in the disease, leading to insufficient levels of IKBKAP protein product as a result of frame-shift-induced nonsense-mediated decay.
Kinetin stimulates skin cells at the deepest layers of skin's surface to keep them healthier longer. It is Kinerase's signature ingredient that has successfully transformed women's skin for more than 10 years, visibly improving wrinkles, tone and texture.
