L-Arginine promotes trophoblast invasion in placental implantation by activating the GPRC6A/PI3K/AKT axis. A. RT-qPCR detection to detect GPRC6A expression. B. CCK8 to detect cell proliferation. C. Cell scratch assay to detect cell migration. D. Transwell assay to detect cell invasion. E. Western blot to detect p-PI3K, PI3K, p-AKT, AKT, GPRC6A, MMP2, and MMP9 expression. *p < 0.05 vs. L-Arginine. #p < 0.05 vs. L-Arginine + si-NC
