The level of G6PDH was on average two to threefold higher in UOK262, UOK262EV and UOK268 cancer cells than in the HRCE cells, while FH restoration in UOK262WT cells caused a reduction of the G6PDH level, more closely approximating those observed in the HRCE cells (Figure 5A). The gene discussed is H6PD; the disease is cancer.
