HOXC11 functions as a novel oncogene in human colon adenocarcinoma and kidney renal clear cell carcinoma

In this study, we comprehensively analyzed the expression profile and prognostic value of HOXC11 in human pan-cancer using online The Cancer Genome Atlas (TCGA) databases. HOXC11 was widely up-regulated in tumor tissues when compared with the normal tissues in pan-cancer across nine cancer types. In addition, high mRNA level of HOXC11 predicted poor overall survival (OS) of patients with adrenocortical carcinoma (ACC), colon adenocarcinoma (COAD), kidney renal clear cell carcinoma (KIRC), mesothelioma (MESO) and pancreatic adenocarcinoma (PAAD), respectively. By comparative analysis, we found that HOXC11 was up-regulated and closely correlated patient OS in COAD and KIRC. Functionally, down-regulation of HOXC11 inhibited cell proliferation but promoted apoptosis of COAD and KIRC in vitro. Mechanistically, HOXC11 promoted cell proliferation of COAD and KIRC might by inactivating the peroxisome proliferator-activated receptor gamma (PPARγ) signaling pathway.SignificanceOur findings suggest that HOXC11 may act as a tumor driving gene in COAD and KIRC.

Notch signaling is a highly conserved intercellular pathway with tightly regulated and pleiotropic roles in normal tissue development and homeostasis. Dysregulated Notch signaling has also been implicated in human disease, including multiple forms of cancer, and represents an emerging therapeutic target. Successful development of such therapeutics requires a detailed understanding of potential on-target toxicities. Here, we identify autosomal dominant mutations of the canonical Notch ligand Jagged1 (or JAG1) as a cause of peripheral nerve disease in 2 unrelated families with the hereditary axonal neuropathy Charcot-Marie-T...
