MMP9 and cervical cancer: To generalize our findings, we studied the impact of MMP‐9 on MICA/B in the Hela cervical cancer that is known to express high levels of MICA/B.[19] Similarly, MMP‐9 also decreased cell surface expression levels of MICA/B in Hela cells and SB‐3CT counteracted the MMP‐9 effect (Figure S6E,F, Supporting Information).
