NR3C1 and gastric cancer: With protein expression tested in seven gastric cancer cell lines (Figure S3E, Supporting Information), NR3C1 was knocked down using three shRNA lentiviruses in HS‐746T cells and overexpressed with the NR3C1 vector in MKN45 and HS‐746T cells (HS‐746T‐OE and MKN45‐OE cells) (Figure3A).
