Validated targets of miR-133a are actin-related protein 2/3 complex, subunit 5 (ARPC5) in lung SCC [67]; caveolin 1 (CAV1) in HNSCC [74]; fascin homolog 1 (FSCN1) in BC [75] and ESCC [69]; glutathione S-transferase pi 1 (GSTP1) in HNSCC [76] and BC [77]; LASP1 in BC [72]; pyruvate kinase, muscle (PKM2) in tongue SCC [78]; PNP in maxillary sinus SCC [38] and PCa [58]; and TAGLN2 in maxillary sinus SCC [38] and BC [59]. The gene discussed is CAV1; the disease is posterior cortical atrophy.
