PTBP1 and stroke disorder: Previous studies have identified several targets of miR-124, such as PTB/hnRNP I (PTBP1) and SRY-box transcription factor (Sox9), which participate in neuronal differentiation (Faraone et al., 1993; Cheng et al., 2009); and Jagged1 (JAG1), which mediates neurogenesis in stroke (Liu et al., 2011).
