PRKCD and hepatocellular carcinoma: To confirm our assumption, the expression level of cellular PRKCD was first suppressed by si-PRKCD transfection (si-PRKCD-1 with better inhibition performance was selected in this section), and the PRKCD-silencing HCC cells were then utilized to stimulate the isolated platelets by direct contact, eventually, the activation level of platelets was analyzed by flow cytometric assay.
