Fig. 3From: Epitelial-to-mesenchimal transition and invasion are upmodulated by tumor-expressed granzyme B and inhibited by docosahexaenoic acid in human colorectal cancer cellsEctopic GrB upmodulates EMT in CRC cells. GrB negative (SW480, SW620, LoVo) and GrB positive (HT-29) CRC cells were transfected with human GrB vector (pCMV-GrB); Mock-transfected cells were used as control. a GrB transfection efficacy was verified by WB; EMT was investigated analyzing the expression of 3 EMT biomarkers (Snail 1, and E- and N-cadherin) by WB; β-actin was used as loading control; numbers indicate band intensities (b.i.) = band volume/area x mean pixel intensity, normalized for β-actin and quantified using Quantity One 1-D analysis software. b Invasion assay was performed using cells transfected with GrB (pCMV-GrB) or Mock; * p < 0.01; **p < 0.0001.
