Relative expression levels of PKD1 in different groups as detected by Real-time PCR.

There were no significant differences between the non-infected and con-shRNA group with respect to the level of PKD1 mRNA. Compared with Con-shRNA group, the mRNA levels of PKD1 in lentivirus-shRNA#1, 2, 3 and 4 subgroups were reduced by 30.9%, 69.1%, 42.6%, and 47.9%, respectively. Each experiment was performed three times individually. Results are presented as the mean ± SEM, * indicates significantly different than controls (*, p
