The Role of Tuftsin in Cancer Treatment

Tuftsin is a peptide that has been found to play an important role in cancer treatment. It has a primary structure composed of four amino acids; lysine, proline, threonine, and arginine. Tuftsin has been proven to stimulate the destruction of tumor cells, and is therefore used in a number of cancer treatments. According to one study, “Tuftsin was found to possess a potent anti-tumor activity, which is mediated by the induction of apoptosis.” (Wang, et al. 2020). This means that tuftsin is capable of triggering the programmed cell death of tumor cells, thereby inhibiting their further growth and progression. The primary structure of tuftsin is composed of three peptide bonds, which link the amino and carboxyl groups of lysine and proline, as well as the threonine and arginine (Wang, et al. 2020). These peptide bonds enable the tuftsin molecule to interact with receptors on the surface of tumor cells, thereby triggering programmed cell death. The amino group of arginine is not linked to any other amino acid, which is necessary in order to activate the anti-tum… Cont…
