Similarly, research by Xiannan Meng and team has shed light on microRNA-126-5p’s ability to suppress BCAR3 expression in endometriosis [13], while Kun Zhou and his team’s discovery of a tRNA fragment, tRF5-Glu, underscores its regulatory influence in ovarian cancer by downregulating BCAR3 mRNA. The gene discussed is BCAR3; the disease is ovarian cancer.
