In order to investigate the mechanism of reproductive toxicity, primary cultured rat Sertoli cells were exposed to 5, 15, or 30 μg/mL TiO<sub>2</sub> NPs for 24 h, and TiO<sub>2</sub> NPs internalization, expression of PKC (p-PKC) and p38 MAPK (p-p38 MAPK) as well as calcium homeostasis were examined.
Ovarian cancer OVCAR3 cells were transfected with the miR-940 vector, miR-940 inhibitor, and/or small interfering RNA (siRNA) targeting PKC-δ (si-PKC-δ), respectively.
Here, we further report that the delta-isoform of PKC (PKCdelta) is also activated by thrombin and involved in the thrombin-mediated augmentation of collagen gel contraction.
