Figure 3: Semi-quantitative RT-PCR to reveal relative expression levels of various toll-like receptor (TLR) genes including TLR-2 to TLR-9 from cultured OC-3-VGH ovarian () and C-33A cervical () cancer cells, respectively. Lane 1: TLR-2; Lane 2: TLR-3; Lane 3: TLR-4; Lane 4: TLR-6; Lane 5: TLR- 7; Lane 6: TLR-9. Expression of GAPDH gene served as the internal control. Percent expression levels of various TLR genes with respect to that of GAPDH are presented for comparisons.
