ARPC1B contributes to colorectal cancer progression and is associated with programmed death-ligand 1 expression

Figure 6 ARPC1B regulates programmed death-ligand 1 expression to promote colorectal cancer progression. A: Cell counting kit-8 assay showed the light absorption value at 450 nm after 48 hours of HT29 and SW620 cells proliferation; B and C: Transwell showed the invasion of HT29 and SW620 cells under negative control, ARPC1B-short hairpin RNA (sh-ARPC1B), programmed death-ligand 1 (PD-L1)-over expression and sh-ARPC1B + PD-L1-over expression condition (n = 3). scale bar = 100 μm. ^aP < 0.05. ^bP < 0.01. ^cP < 0.001. NC: Negative control; sh-ARPC1B: ARPC1B-short hairpin RNA; PD-L1: Programmed death-ligand 1; OE: Over expression; OD: Optical density.
