DNA electrophoretic mobility shift assays were performed with nuclear extracts from HepG2 cells treated with 10 \u03bcmol\/L AFB, 40 \u03bcmol\/L BP, or 300 \u03bcmol\/L 4-ABP for 6 and 24 hours. Eight- and 6-fold increases in nuclear transcription factor \u03baB (NF-\u03baB), and 5- and 10-fold increases in activated protein (AP-1) transcription factor were observed with 24 hours AFB and BP treatments, respectively, whereas 4-ABP treatment resulted in an approximately 4-fold induction of both NF-\u03baB and AP-1. Moreover, 4-ABP gave the strongest NF-\u03baB activation in 6 hours of treatment. Four- and 10-fold activation of stress protein was detected by a consensus heat shock factor (HSF) sequence binding probe, with AFB and BP treatments, respectively. DNA adducts were observed by immunoassays in HepG2 cells treated with AFB and BP but not with 4-ABP. Increased human hepatitis B virus (HBV) surface antigen (HBsAg) synthesis was detected in AFB- and BP-treated HepG2 cells following transfection with recircularized HBV DNA. These data suggest that certain carcinogen-induced transcription factors may influence viral carcinogenesis and initiate hepatocellular carcinomas (HCC).<\/jats:p>\n          <\/jats:sec>","DOI":"10.1053\/jhep.2000.9197","type":"journal-article","created":{"date-parts":[[2004,3,19]],"date-time":"2004-03-19T22:03:01Z","timestamp":1079733781000},"page":"367-374","update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":19,"title":["Effects of carcinogen-induced transcription factors on the activation of hepatitis B virus expression in human hepatoblastoma HepG2 cells and its implication on hepatocellular carcinomas"],"prefix":"10.1097","volume":"32","author":[{"given":"Ranjit","family":"Banerjee","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lorraine","family":"Caruccio","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yu Jing","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Scott","family":"McKercher","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Regina M.","family":"Santella","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"10.1053\/jhep.2000.9197-BIB1","doi-asserted-by":"crossref","first-page":"406","DOI":"10.1126\/science.6264599","volume":"213","author":"Tiollais","year":"1981","journal-title":"Science"},{"key":"10.1053\/jhep.2000.9197-BIB2","doi-asserted-by":"crossref","first-page":"489","DOI":"10.1038\/317489a0","volume":"317","author":"Tiollais","year":"1985","journal-title":"Nature"},{"key":"10.1053\/jhep.2000.9197-BIB3","doi-asserted-by":"crossref","first-page":"651","DOI":"10.1146\/annurev.bi.56.070187.003251","volume":"56","author":"Ganem","year":"1987","journal-title":"Annu Rev Biochem"},{"key":"10.1053\/jhep.2000.9197-BIB4","doi-asserted-by":"crossref","first-page":"475","DOI":"10.1146\/annurev.mi.45.100191.002355","volume":"45","author":"Sherker","year":"1991","journal-title":"Annu Rev Microbiol"},{"key":"10.1053\/jhep.2000.9197-BIB5","doi-asserted-by":"crossref","first-page":"297","DOI":"10.1146\/annurev.med.45.1.297","volume":"45","author":"Robinson","year":"1994","journal-title":"Annu Rev Med"},{"key":"10.1053\/jhep.2000.9197-BIB6","doi-asserted-by":"crossref","first-page":"29","DOI":"10.1146\/annurev.iy.13.040195.000333","volume":"13","author":"Chisari","year":"1995","journal-title":"Annu Rev Immunol"},{"key":"10.1053\/jhep.2000.9197-BIB7","doi-asserted-by":"crossref","first-page":"303","DOI":"10.1038\/373303a0","volume":"373","author":"Ghosh","year":"1995","journal-title":"Nature (London)"},{"key":"10.1053\/jhep.2000.9197-BIB8","doi-asserted-by":"crossref","first-page":"540","DOI":"10.1126\/science.3140380","volume":"242","author":"Baeuerle","year":"1988","journal-title":"Science"},{"key":"10.1053\/jhep.2000.9197-BIB9","doi-asserted-by":"crossref","first-page":"649","DOI":"10.1146\/annurev.immunol.14.1.649","volume":"14","author":"Baldwin","year":"1996","journal-title":"Annu Rev Immunol"},{"key":"10.1053\/jhep.2000.9197-BIB10","doi-asserted-by":"crossref","first-page":"255","DOI":"10.1016\/S0065-230X(08)60257-2","volume":"66","author":"Miyamoto","year":"1995","journal-title":"Adv Cancer Res"},{"key":"10.1053\/jhep.2000.9197-BIB11","doi-asserted-by":"crossref","first-page":"1008","DOI":"10.1002\/hep.1840100620","volume":"10","author":"Banerjee","year":"1989","journal-title":"Hepatology"},{"key":"10.1053\/jhep.2000.9197-BIB12","doi-asserted-by":"crossref","first-page":"729","DOI":"10.1016\/0092-8674(87)90611-8","volume":"49","author":"Angel","year":"1987","journal-title":"Cell"},{"key":"10.1053\/jhep.2000.9197-BIB13","doi-asserted-by":"crossref","first-page":"129","DOI":"10.1006\/faat.1997.2371","volume":"40","author":"Hasmall","year":"1997","journal-title":"Fund Appl Toxicol"},{"key":"10.1053\/jhep.2000.9197-BIB14","doi-asserted-by":"crossref","first-page":"601","DOI":"10.1146\/annurev.cb.09.110193.003125","volume":"9","author":"Georgopoulos","year":"1993","journal-title":"Annu Rev Cell Biol"},{"key":"10.1053\/jhep.2000.9197-BIB15","doi-asserted-by":"crossref","first-page":"1409","DOI":"10.1126\/science.8451637","volume":"259","author":"Morimoto","year":"1993","journal-title":"Science"},{"key":"10.1053\/jhep.2000.9197-BIB16","doi-asserted-by":"crossref","first-page":"441","DOI":"10.1146\/annurev.cb.11.110195.002301","volume":"11","author":"Wu","year":"1995","journal-title":"Annu Rev Cell Dev Biol"},{"key":"10.1053\/jhep.2000.9197-BIB17","first-page":"417","volume-title":"The Biology of Heat Shock Proteins and Molecular Chaperones","volume":"26","author":"Morimoto","year":"1994","unstructured":", , , , , , et al.
