CXCR1 and glioblastoma: These results indicate that CXCR1 was overexpressed in 66.7% (n = 6) of MYT1L-positive brain cancer cell lines examined, implicating a contributing role of MYT1L in CXCR1 transcription, despite the Cancer Genome Atlas (TCGA) data analysis that showed no correlation between the levels of MYT1L mRNA and CXCR1 mRNA in both glioblastoma (R2 = −0.016309) and neuroblastoma (R2 = −0.032546) (Supplementary Figure S2).
