Figure 2. Western blotting detection for cytokeratin 5, 10, 14, and loricrin, involucrin, and transglutaminase-1 (TGM1) expression in normal human epidermal keratinocytes (NHEKs) after shRNA silencing. LV group: filaggrin-silenced cells; NC group: shRNA control cells; Blank group: noninfected cells. *P<0.05, **P<0.01 vs Blank group; #P<0.05, ##P<0.01 vs NC group (least significant difference test).
