A tumorigenic human hepatoma cell line, Hep G2, has been shown to have high steady-state levels of c-myc transcripts compared to normal human liver. We have now characterized c-myc expression in Hep G2 cells with regard to message stability, gene rearrangements, gene amplification, chromosomal translocations, promoter utilization, and the effects of protein synthesis inhibitors. We have determi...

The aim of our work was to compare cytotoxic and membrane-damaging effects of O. majorana L. essential oil and linalool on Hep G2 and to investigate their possible protective (antioxidant) effects against H2O2 induced membrane damage. The oils were investigated by GC and GC-MS and antioxidant activity was evaluated by DPPH and -carotene–linoleic acid assays. Assessment of cell viability was ma...

BACKGROUND AND OBJECTIVES Human papillomaviruses have been linked causally to some human cancers such as cervical carcinoma, but there is very little research addressing the effect of HPV infection on human liver cells. We chose the human hepatoma derived cell line Hep G2 to investigate whether HPV gene integration took place in liver cells as well. METHODS We applied PCR to detect the possib...

The combined cytoactive effects of American ginseng (Panax quinquefolius) and licorice (Glycyrrhiza uralensis) root extracts were investigated in a hepatocarcinoma cell line (Hep-G2). An isobolographic analysis was utilized to express the possibility of synergistic, additive or antagonistic interaction between the two extracts. Both ginseng and licorice roots are widely utilized in traditional ...

Atractylis lancea (Thunb.) DC. (AL), an important medicinal herb in Asia, has been shown to have anti-tumor effects on cancer cells, but the involved mechanisms are poorly understood. This study focused on potential effects and molecular mechanisms of AL on the proliferation of the Hep-G2 liver cancer cell line in vitro. Cell viability was assessed by MTT test in Hep-G2 cells incubated with an ...

Human hepatoma (Hep G2) cells have been shown to secrete nanogram quantities of carboxypeptidase N (Grimwood, B. G., Plummer, T. H., Jr., and Tarentino, A. (1988) J. Biol. Chem. 263, 14397-14401). A second carboxypeptidase with an acidic pH optimum (pH 5.5) is also secreted at levels 2-3-fold greater than carboxypeptidase N. This enzyme was partially purified from the conditioned medium and com...

In the present work a series of novel 2,4-disubstituted -1, 5 -diphenyl substituted -1H-imidazole derivatives were screened for anticancer activity using human liver cancer cell line. Derivatives were evaluated for anticancer activities against Hep G2 (Human liver cancer) cell lines. Newly synthesized compounds A-IVn, A-IVo,B-IVb, B-IVc, B-IVd, and B-IVe showed highly significant cytotoxic acti...

Bog bilberry (Vaccinium uliginosum L.) is a blue-pigmented edible berry related to bilberry (Vaccinium myrtillus L.) and the common blueberry (Vaccinium corymbosum). The objective of this study was to investigate the effect of a bog bilberry anthocyanin extract (BBAE) on cell growth, membrane permeability, and cell cycle of 2 malignant cancer cell lines, Caco-2 and Hep-G2, and a nonmalignant mu...
