SASH1 and head and neck squamous cell carcinoma: To explain how miR‐9 may possibly regulate the tumorigenic potential of HNSCC cells, we first looked to the oncosuppressor SASH1 that we previously showed to be a bona fide miR‐9 target in HNSCC (Citron et al,2017) and has been involved in the regulation of EMT in different tumor types, including cutaneous SCC (He et al,2016; Chen et al,2020; Franke et al,2020).
