Indeed, besides our own microarray dataset (GSE13597), we found that FJX1 is also overexpressed in independent NPC microarray dataset (GSE12452) (2.8 fold), as well as colorectal and ovarian cancers [18, 19] (2.4- and 2.3-fold, respectively; p < 0.01) when compared to normal tissues (Table 1). Here, FJX1 is linked to nasopharyngeal carcinoma.
