TNS4 promotes lymph node metastasis of gastric cancer by interacting with integrin Β1 and inducing the activation of fibroblastic reticular cell.

ABSTRACT: Lymph node (LN) metastasis of gastric cancer (GC) is one of the important pathways of GC metastasis, indicating the clinical staging and prognosis of patients. To investigate the underlying mechanism during the process of GC-induced LN metastasis, 7 pairs of GC tissues, paracancerous (PC) tissues, GC-positive LN (LN.P) and GC-negative LN (LN.N) tissues from GC patients with homogeneity were selected for RNA sequencing (RNA-seq) analysis. Tensin 4 (TNS4) was screened out and found to be significantly upregulated in LN.P tissues and closely related with the characteristics of GC. In vitro and in vivo experiments demonstrated that knockdown of TNS4 could significantly inhibit LN metastasis of GC cells and activation of fibroblastic reticular cells (FRCs) in LNs, thus inhibiting LN expansion i
