(A) Matrigel invasion assay of Sawano cells transfected with or without siRNAs of lipolysis-stimulated lipoprotein receptor (LSR) and claudin-1 (CLDN-1). Scale bar, 200 µm. The results are presented below as a histogram. Control vs. siRNA-LSR, **P<0.01; siRNA-LSR vs. siRNAs-LSR/CLDN-1, ^##P<0.01. (B) H&E and immunohistochemical staining for LSR and CLDN-1 in human endometrial carcinoma (arrowheads indicate the invasive front; arrows indicate the gland-like structure). Scale bar, 100 µm. siRNA, small interfering RNA; LSR, lipolysis-stimulated lipoprotein receptor; CLDN, claudin; H&E, hematoxylin and eosin.
