HSP90B2P and colorectal cancer: HSP70 (Fig. 4g) and HSP90 (Fig. 4h) surface expression were exclusively increased on tumor cells after 120 s kINPen plasma treatment, while both 240 s of kINPen plasma treatment, as well as 120 s and 240 s of Vjet plasma treatment, did not potentiate HSP expression on the colorectal cancer cells.
