Genetic disruption of COX-1 inhibits multiple oncogenic pathways


ABSTRACT: We performed RNA sequencing in isogenic models of COX-1 proficient (OV3/SCR) and COX-1 deficient (OV3/COX1KD) OVCAR-3 ovarian cancer cells. COX-1 knockdown was associated with a coordinated anti-oncogenic phenotype, with growth, angiogenesis, migration/invasion, and epithelial-mesenchymal transition among the pathways down-regulated. RNA sequencing was performed at Vanderbilt Technologies for Advanced Genomics (VANTAGE) using Illumina HiSeq 2500.

Cyclooxygenase-1 (COX-1) is implicated in ovarian cancer. However, patterns of COX expression and function have been unclear and controversial. In this report, patterns of COX-1 and COX-2 gene expression were obtained from RNA-seq data through The Cancer Genome Atlas. Our analysis revealed markedly higher COX-1 mRNA expression than COX-2 in high-grade serous ovarian cancers (HGSOC) and higher COX-1 expression in HGSOC tumors than 10 other tumor types. High expression of COX-1 in HGSOC tumors was  ...[more]
