SGK3 and cancer: Previous work has shown that SGK3 is overexpressed in a variety of cancer cell lines and knockdown of SGK3 in these cells including in ZR‐75‐1 cells employed in this study has substantial impact on proliferation (Virbasius et al, 2001; Gasser et al, 2014; Chi et al, 2015), results we have been able to confirm (RB, data not shown).
