A. TIGK cells were transfected with siRNA to JNK or scrambled siRNA (siRNA Control). Control cells were non-transfected. Cell lysates were immunoblotted with JNK antibodies or GAPDH antibodies as a loading control.
B. Transfected TIGK cells were infected with P. gingivalis 33277 MOI 10 (Pg) for 2 h and Cat, Sod2 Prdx3, Bcl-6 and IL-1β mRNA levels were measured by qRT-PCR. Data were normalized to GAPDH mRNA and are expressed relative to non-infected (NI) siRNA controls. Results are means ± standard deviation (SD); n = 3; *P < 0.05; **P < 0.01.
C. Transfected TIGK cells were infected with P. gingivalis 33277 MOI 10 (Pg) for 2 h, or left uninfected (NI), and IL-1β levels in culture supernatants were determined by ELISA. Results are mean ± SD; n = 3; *P < 0.05; **P < 0.01.
