Urolithins are evolving subjects in cancer biology and one particular that may open doors for the development of new therapy for the management and treatment of several cancer forms. As summarized in this overview, the ellagitannin and ellagic acid anticancer properties are mainly resulting from their gut-derived metabolites, the urolithins. Numerous on the anticancer activities attributed to urolithins involve cell cycle arrest and apoptosis induction. Other mechanisms include modulation of pathways connected with cell proliferation, cell survival, oxidative pressure, detoxification, along with the modulation of pathways involving CYP26 custom synthesis hormonal actions (Figure two and Table two). It is noteworthy that oral administration of chemically synthesized urolithin A has been not too long ago located to be safe in humans (135). Also, the US Food and Drug Administration has previously offered Uro A a favorable critique in its generally safe (GRAS) notification program, and 1,000 mg/serving of urolithin A might be utilised as a functional food ingredient (136). The urolithins anticancer activities are comparable to other established polyphenols with anticancer potentials like curcumin and resveratrol. By way of example, curcumin, on the list of many phenolic pigments discovered in nature, is obtained from the plant Curcuma longa L. Its anticancer activities in various cancer sorts have already been attributed to its prospective to modulate celldifferentiation, cell cycle arrest, and apoptosis (137). Curcumin causes the suppression of NF-B (a transcription issue whose constitutive expression is implicated in a lot of cancers), major to a lower in its target genes such as COX-2 and cyclin D1 and in the end top to apoptosis (four). In addition, curcumin inhibits cell development and invasion by means of the downregulation of EGFR and MMP-2 genes’ expression, respectively (6). Similarly, resveratrol is often a dietary polyphenol obtained from plants. Its capability to trigger cell cycle arrest and induce apoptosis has been demonstrated in each in vivo and in vitro cancer models (138). Resveratrol inhibits metastasis in colon cancer cells by decreasing the expression of hypoxia-inducible factor-1 (HIF1) and MMP-9 (139). In prostate cancer, resveratrol has been identified to attenuate cell proliferation and upregulate the induction of apoptosis by either decreasing the activation of MAPK or NF-B induced inactivation (140). The mechanisms of action of curcumin and resveratrol are similar to what has been reported so far for the urolithins (Table two). On the other hand, as the majority of the urolithins’ reported anticancer activities were carried out by way of in vitro research, caution has to be made to translate it into what happens in vivo. Nonetheless, the research on urolithins will likely be an interesting 1 inside the coming days ahead.AUTHOR CONTRIBUTIONSSA-H, AA, MZ, and MK contributed to the manuscript’s conception and improvement.
