Anticancer Effects of LBA-ST Yogurt Supernatant on HeLa Cells via Heat Shock Protein 27 Decrease In Vitro

Liziyyannida Liziyyannida, Wibi Riawan


Heat Shock Protein 27 (Hsp27) is overexpressed in cervical cancer as a response to stress conditions. Hsp27 overexpression increase invasion, migration, and adhesion pathways of cancer cells. The Yogurt supernatant contains Short-Chain Fatty Acids (SCFA) include acetate, lactate, and butyrate which have anticancer activity. This study aimed to investigate supernatant of LBA-ST (Lactobacillusbulgaricus-acidophilus, Streptococcusthermophillus) Yogurt can decrease the expression of Hsp27 in HeLa culture cells. The mechanism on how supernatant yogurt inhibit invasion, migration, and adhesion was studied by immunocytochemistry. The data was then collected and analyzed using One-Way ANOVA. From this study, it can be concluded that the expression of proteins that play a role in invasion, adhesion, and migration of the Hsp27 was proven to be decreased (p< 0.05 ± 0.005).
