TBC1D8 expression inhibits OVCA cell PK activity and increases cell glucose uptake and lactate production. (A) OV-3 cells were transfected with the indicated amount of TBC1D8 vector, and the PK activity was evaluated (n=3). (B) OV-3high cells were transfected with two anti-TBC1D8 siRNAs, and the PK activity was determined (n=3). (C) PK activity was determined in OV-3high cells with TBC1D8 expression stably silenced (n=3). (D) PK activity was determined in mouse xenograft tumors composed of OV-3high cells with TBC1D8 expression stably silenced, as described in Figure 3E (n=3). (E, G) OV-3 cells were transfected with the indicated amount of TBC1D8 vector, and glucose uptake (E) and lactate production (G) were determined (n=3). (F, H) OV-3high cells were transfected with two anti-TBC1D8 siRNAs, and glucose uptake (F) and lactate production (H) were determined (n=3).
