Interestingly, C19orf33 expression in cancer cell lines showed a negative correlation with the IC50 values of the kinase (MEK, ERK, SRC) inhibitors for the cell lines (additional file 3: Table S3), suggesting that cancer cell lines with higher C19orf33 expression are more sensitive to kinase inhibitors than those with lower C19orf33 expression. Here, C19orf33 is linked to cancer.
