Abstract
Prebiotics and probiotics have gained much attention in the pursuit of a healthy life. Recently, postbiotics have been spotlighted as next-generation compounds that can improve health. Postbiotics are designated into non-viable, inactivated, and ghost probiotics, and linked to several health benefits for the gut, immune system, and various other aspects of health. This study investigated the anti-proliferation effects of postbiotics against HT-29 cells, a colon cancer cell line. The postbiotics were produced by the ultrasonication method from two Lactobacillus strains (Lactobacillus sp. La1, and La2) and designated to Pobt-La1 and Pobt-La2, respectively, and non-viability was confirmed on the plate media. The anti-proliferation effect was concentration-dependent. The HT-29 cells showed viabilities of 39% and 49% when treated with 300 µL/mL of Pobt-La1 and Pobt-La2, respectively. During observation of the morphological changes of HT-29 cells when treated with IC50, a cell nucleus was not observed but cell condensation was observed. Moreover, in comparison with the control group, a reduced number of cells were observed. Based on these results, it considered that the postbiotic compounds from Lactobacillus La1 and La2 could provide crucial information in the development of anticancer research. Through further research, it would be beneficial to investigate the possibility of using these postbiotics (Pobt-La1 and -La2) as an anticancer drug.
