Moreover, the mechanism associated with the suppression of liver cancer cell proliferation by STT was also studied. The results revealed that STT suppresses proliferation of SNU449 and Huh7 cells to 28 and 21%, respectively treatment with 20 µM. The clonogenic survival of SNU449 and Huh7 cells was also significantly reduced after incubation with STT compared to the control cultures. In comparison to the control, STT treatment significantly decreased the invasive potential of SNU449 cells. Treatment with STT led to a prominent suppression in p62 and increase in LC3B protein expression in SNU449 cells compared to the control cells. The STT treatment dramatically decreased p-Akt and p-mTOR protein expression in SNU449 cells. Docking study revealed that STT interacts <i>via</i> traditional hydrogen bonding with the glutamine, phenylalanine, leucine, serine, arginine, aspartic acid, and lysine residues of Akt protein. In summary, the current study demonstrates that STT effectively suppresses the viability of SNU449 and Huh7 liver cancer cells. Moreover, STT treatment of the liver cancer cells also significantly reduces the clonogenic survival and invasive potential of SNU449 cells. Treatment of liver cancer cells with STT increases the expression of autophagic, targets anti-autophagic protein expression and down-regulates Akt/mTOR pathway to inhibit cancer growth and proliferation. Thus, STT exhibits prominent anticancer effect and needs to be investigated further as a potential candidate for the treatment of liver cancer.</p>","PeriodicalId":529,"journal":{"name":"Doklady Biochemistry and Biophysics","volume":"517 1","pages":"277 - 284"},"PeriodicalIF":0.8,"publicationDate":"2024-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141603165","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
