To identify the potential role of XPA mRNA expression in different cancer types, Wu et al. [156] used two approaches: (i) comparison of the XPA mRNA expression in 13 types of cancers from the RNA sequencing dataset platform GENT (Gene Expression Database of Normal and Tumor Tissues, http://medical-genome.kribb.re.kr/GENT/) and (ii) freely available information on XPA expression in 19 types TCGA (The Cancer Genome Atlas) datasets and their normal controls from ONCOMINE, a cancer microarray database and web-based data-mining platform (https://www.oncomine.org/). The gene discussed is XPA; the disease is neoplasm.
