Figure 8. Effects of Caprin-2 overexpression or knockdown on AVP mRNA levels in vitro.
For Caprin-2 knockdown experiments, cells were co-transfected with the CMV-driven rat Caprin-2 overexpression construct, the CMV-driven rat AVP structural gene, and either scrambled shRNA (Ctrl) or Caprin-2 shRNA (Cap2 KD) constructs. Caprin-2 knockdown (Cap2 KD) reduces (A) Caprin-2 (Ctrl, 1.00 ± 0.03 vs Cap2 KD, 0.13 ± 0.01, n = 5, p ≤ 0.0001) and (B) AVP (Ctrl, 1.00 ± 0.02 vs Cap2 KD, 0.76 ± 0.02; n = 5, p ≤ 0.0001) mRNA levels. In the Caprin-2 overexpression experiments, the CMV-driven rat AVP structural gene was co-transfected with either the CMV-driven rat-Caprin-2 overexpression construct (Cap2), or a control CMV-eGFP construct (Ctrl). (C) Caprin-2 overexpression increases the level of AVP mRNAs (Ctrl, 1.0 ± 0.05 vs Cap2, 2.17 ± 0.14, n = 5, p ≤ 0.0001). ****p ≤ 0.0001.
