ANXA1 and head and neck squamous cell carcinoma: Even though the differences in ANXA1 protein levels following pre-miR196a overexpression were marginal, pre-miR196b overexpression consistently led to a significant reduction of ANXA1 expression at both mRNA and protein levels in both full-length (37 kDa) and cleaved form (33 kDa) in the two different HNSCC cell lines tested.
