Figure 3. PDI KD induces ER stress that downregulates RAD51.
qPCR (A-B) and Western blot (C) analysis for PDI and RAD51 expression level after doxycycline induction as indicated. qPCR data are presented as means ± S.D. *, p<0.05; **, p<0.01; ***, p<0.001 from three independent experiments. (D) Immunoblot analysis of CRISPR/Cas9 targeting P4HB U87 cells after 48hrs of infection. (E) Tunicamycin (Tm) was added at 5 μg/ul to D54MG and U87MG cells for 12 hrs and RAD51 and BiP protein expression were assessed.
