Tretinoin 95-99 X protein Hepatitis B virus 24-27 21325480-2 2011 Here, it was shown that HBx overcomes cellular senescence provoked by all-trans retinoic acid (ATRA) in HepG2 cells, as demonstrated by the impaired induction of irreversible G(1) arrest and senescence-associated beta-galactosidase activity by ATRA in the presence of HBx. Tretinoin 244-248 X protein Hepatitis B virus 24-27 21325480-4 2011 In addition, HBx suppressed ATRA-mediated induction of p16 and p21 in HepG2 cells via promoter hypermethylation, resulting in inactivation of retinoblastoma protein. Tretinoin 28-32 X protein Hepatitis B virus 13-16 21325480-5 2011 Furthermore, the ability of HBx to overcome ATRA-induced cellular senescence almost completely disappeared when the levels of p16 and p21 in the HBx-expressing cells became similar to those in the control cells by complementation in the former by exogenous expression, knockdown of their expression in the latter using specific small interfering RNA or treatment with a DNA methylation inhibitor, 5-Aza-2"-deoxycytidine. Tretinoin 44-48 X protein Hepatitis B virus 28-31 19828754-3 2010 In addition, HBx abolished the potential of retinoic acid (RA) to downregulate levels of G(1)-checkpoint regulators including p16, p21 and p27, resulting in activation of E2F1 in the presence of RA. Tretinoin 44-57 X protein Hepatitis B virus 13-16 19828754-3 2010 In addition, HBx abolished the potential of retinoic acid (RA) to downregulate levels of G(1)-checkpoint regulators including p16, p21 and p27, resulting in activation of E2F1 in the presence of RA. Tretinoin 59-61 X protein Hepatitis B virus 13-16 19828754-3 2010 In addition, HBx abolished the potential of retinoic acid (RA) to downregulate levels of G(1)-checkpoint regulators including p16, p21 and p27, resulting in activation of E2F1 in the presence of RA. Tretinoin 195-197 X protein Hepatitis B virus 13-16 31706164-1 2020 Hepatitis B virus (HBV) X protein (HBx) has been reported to counteract the innate immune responses through interfering with the pattern recognition receptors signaling activated by retinoic acid-inducible gene-I (RIG-I)-mitochondrial antiviral signaling protein (MAVS). Tretinoin 182-195 X protein Hepatitis B virus 35-38 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 X protein Hepatitis B virus 78-81 29068287-3 2017 For this effect, HBx upregulated both protein and enzyme activity levels of DNA methyltransferase 1, 3a and 3b, in the presence of ATRA and thereby inhibited p14 expression via promoter hypermethylation, resulting in inactivation of the p14-mouse double minute 2 pathway and subsequent downregulation of p53 levels. Tretinoin 131-135 X protein Hepatitis B virus 17-20 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 X protein Hepatitis B virus 13-16 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. Tretinoin 133-137 X protein Hepatitis B virus 78-81 24227948-4 2013 Many genes involved in hepatic retinoid physiology, including CRBP-I, were altered and the tissue levels of retinol and all-trans retinoic acid (ATRA) were elevated in the liver of HBx Tg mice compared to those of wild type (WT) control mice.
