We also uncovered that C19orf33 expression in cancer cell lines is positively correlated (ρS ≥ 0.3) with the IC50 values of hundreds of chemotherapeutic drugs in those cell lines (additional file 3: Table S3), suggesting that C19orf33 expression may be a general biomarker for cancer cell line sensitivity to chemotherapeutic agents. Here, C19orf33 is linked to cancer.
