A novel long noncoding RNA, TMEM92-AS1, promotes GC progression by binding to YBX1 to mediate CCL5 (335)Down-regulation of KLF5 in cancer-associated fibroblasts inhibit GC cells progression by CCL5/CCR5 axis (336)17β-estradiol inhibits mesenchymal stem cells-induced human AGS GC cell mobility via suppression of CCL5- Src/Cas/Paxillin signaling pathway (337). Here, KLF5 is linked to gastric cancer.
