The level of TTC7B transcription is not only inversely correlated with that of the TTC22 gene but also positively correlated with those of the FTO and PI4KA genes in numerous normal/cancer tissues and cancer cell lines according to The Cancer Genome Atlas (TCGA), Genotype Tissue Expression (GTEx), and Cancer Cell Line Encyclopedia (CCLE) datasets (Figures S1-S3) 12-14. This evidence concerns the gene PI4KA and cancer.
