Effects of tumour necrosis factor-α (TNF-α) on the apoptotic signalling pathway at mRNA level. Subjecting cultured human tenocytes to TNF-α for 7 h significantly increased main parameters of the apoptotic pathway. (A) 500 ng/mL of TNF-α significantly increased caspase-10 mRNA as compared to the control (4.2-fold change; *p<0.05). 50 ng/mL also showed an increase compared to control, although this was not statistically significant (n.s) (p=0.08). (B) In total, 50 ng/mL of TNF-α significantly increased caspase-3 mRNA in comparison to the control (1.8-fold change; *p<0.05). The increase seen for cells treated with 500 ng/mL of TNF-α was not statistically significant (n.s.), although close to significant (p=0.05). Error bars indicate the SD.
