RAC1 and breast cancer: These pathways included four of the predicted target pathways of miR‐576‐5p: “mTOR signaling,” “Ephrin B signaling,” “Breast cancer regulation by stathmin,” and “Production of nitric oxide and ROS in macrophages.” In these pathways, the predicted direct targets of miR‐576‐5p were RAC1 (the small GTPase RAC1), PRKCI (protein kinase C iota), GNAS (stimulatory G‐protein α‐subunit), CFL2 (cofilin 2), and ACP1 (low molecular weight phosphotyrosine protein phosphatase) (Table 6).
