Specific knockdown of HOXB7 inhibits cutaneous squamous cell carcinoma cell migration and invasion while inducing apoptosis via Wnt/β-catenin signaling pathway. Am J Physiol Cell Physiol. 2018 Aug 01;: Authors: Gao D, Chen HQ, Yang YM Abstract Metastatic cutaneous squamous cell carcinoma (CSCC) is a major cause of death associated with non-melanoma skin cancer. The involvement of homeobox B7 (HOXB7) in cancers has been reported. Thus, the current study intends to explore the effect of HOXB7 on CSCC and its relationship with the Wnt/β-catenin signaling pathway. Initially, microarray-based gene expression profiling of CSCC was performed and HOXB7 was identified as an upregulated gene based on the microarray data of GSE2068. Following this, the experimental results indicated that HOXB7 and β-catenin formed a composite, demonstrating that endogenous HOXB7 binds to β-catenin. Subsequently, CSCC cells were treated with siRNA against HOXB7 or inhibitor of Wnt/β-catenin signaling pathway (IWR-1) in order to analyze any underlying regulatory mechanism of HOXB7 on the CSCC cells. Tumor growth involving xenografts in nude mice was also observed so as to explore whether or not HOXB7 could regulate subcutaneous tumor growth through in vivo culturing. In order to investigate the potential effects of HOXB7 on the Wnt/β-catenin signaling pathway, we determined the expression of HOXB7 and downstream genes of the Wnt/β-catenin signaling pathway...
