Meanwhile, it has been reported that lncRNAs could also regulate HR repair.[40] Loss of ATM‐regulated lncRNA, ANRIL, has been shown to impair HR repair in pancreatic cancer cells.[41] In addition, a prostate‐specific lncRNA, PCAT‐1, regulates BRCA2 and controls HR repair in sporadic cancer cells.[42] Lnc‐RI regulates the stability of RAD51 mRNA; and thereby, regulates HR repair of DSB.[43] However, till now, lncRNAs that could simultaneously regulate HR repair in human trophoblast cells and the occurrence of miscarriage have never been reported. This evidence concerns the gene RAD51 and Miscarriage.
