Effects of PBMF on protein expressions of GSK-3β, E-cadherin, N-cadherin and Ki-67 in tumor tissues. a Immunohistochemistry staining of GSK-3β, E-cadherin, N-cadherin and Ki-67 proteins among each group was performed and observed under light microscope (200×). GSK-3β proteins were markedly expressed in the cytoplasm and nucleus; E-cadherin and N-cadherin proteins were markedly expressed in cytomembrane and cytoplasm; Ki-67 proteins were markedly expressed in the nucleus. Red arrows refer to positive staining with pale brown. Semi-quantitative analysis of the intensity of GSK-3β-positive (b), E-cadherin-positive (c), N-cadherin-positive (d) and Ki-67-positive (e) staining was conducted using IOD/area value. ^**p < 0.01 vs. model control.
