Oxidative stress induces the expression of the major histocompatibility complex in murine tumor cells.

2001

The effect of t-butyl hydroperoxide (t-BOOH) on the induction of the Major Histocompatibility Complex (MHC) class I genes has been studied in two cell clones (B9 and G2) of the methylcholanthrene-induced murine fibrosarcoma GR9. These two clones were selected based on their different biological and biochemical behavior specially related to their tumor induction capability when injected into a BALB/c mouse. t-BOOH (0.125 mM) induced the expression of H-2 molecules in both cell clones. In B9 cell clone, in which MHC basal expression is very low or absent, t-BOOH significantly induced H-2Kd, H-2Dd and H-2Ld molecules. In G2 cell clone the expression of MHC class I genes was also enhanced by th…

Role of glutathione in the induction of apoptosis and c-fos and c-jun mRNAs by oxidative stress in tumor cells.

2003

We have used two tumor cell clones (B9 and G2), derived from the methylcholanthrene-induced murine fibrosarcoma GR9 and normal BALB/c3T3 fibroblasts, to study the ability of t-BOOH derived reactive oxygen radicals to induce oxidative stress, apoptosis and c-fos and c-jun mRNA transcription. These clones differ in terms of their major histocompatibility complex (MHC) (H-2) class I genes expression, their tumor induction and metastatic potential and their reduced glutathione (GSH) levels. Incubation of both cell clones in the presence of t-BOOH results in the increase of 8-oxo-2'-deoxyguanosine (8-oxo-dG) and malondialdehyde and the decrease of GSH. The xenobiotic also induces the transcripti…
