Tretinoin 0-23 tumor protein p53 Homo sapiens 162-165 29068287-1 2017 All-trans retinoic acid (ATRA), the most biologically active metabolite of vitamin A, is known to activate p14 expression via promoter hypermethylation to induce p53-dependent apoptosis in human hepatocytes. Tretinoin 25-29 tumor protein p53 Homo sapiens 162-165 29068287-2 2017 In this study, we found that the oncogenic hepatitis B virus (HBV) X protein (HBx) of HBV, derived from both overexpression and 1.2-mer replicon systems, suppresses ATRA-induced apoptosis in p53-positive human hepatocytes. Tretinoin 165-169 tumor protein p53 Homo sapiens 191-194 29068287-4 2017 As a result, HBx was able to impair the potential of ATRA to activate apoptosis-related molecules, including Bax, p53-upregulated modulator of apoptosis, caspase-9, caspase-3 and poly (ADP-ribose) polymerase. Tretinoin 53-57 tumor protein p53 Homo sapiens 114-117 29068287-5 2017 In conclusion, the present study provides a new oncogenic action mechanism of HBx, namely by suppressing the anticancer potential of ATRA to induce p53-dependent apoptosis in HBV-infected hepatocytes.
