In addition to its antioxidant properties and ability to modulate cellular signaling pathways, selenomethionine has been shown to possess the remarkable capability of inhibiting the growth and proliferation of prostate cells. This attribute of selenomethionine is particularly relevant in the context of prostate health, as it can potentially contribute to the management and prevention of various prostate-related conditions.

  1. Suppression of Prostate Cell Proliferation: Numerous studies have demonstrated that selenomethionine can effectively suppress the proliferation of both normal and abnormal prostate cells. This inhibitory effect on cell growth is thought to be mediated through several mechanisms, including cell cycle arrest, the induction of apoptosis, and the modulation of key signaling pathways involved in cell division and survival.

  2. Regulation of Cell Cycle Progression: Selenomethionine has been found to disrupt the normal progression of the cell cycle in prostate cells. It can induce cell cycle arrest at specific checkpoints, preventing the cells from entering the next phase of division and ultimately inhibiting their proliferation. This cell cycle regulation is a crucial aspect of selenomethionine's ability to control the growth of prostate cells.
