GHSR and breast cancer: As shown in Figure 3, the transduction of GHSR1a‐shRNA resulted in a considerable decrease in the levels of GHSR1a protein (Fig. 3A) and mRNA (Fig. 3B) compared with that of SC group cells or BC group cells (P < 0.05), whereas the expression of GHSR1a was similar between SC group cells and BC group cells at the transcriptional as well as translational levels.
