When considering drugs by class of chemotherapeutic, SLFN11 was the only transcript correlated (R≤-0.2) with sensitivity to at least half of tested chemotherapeutics in 4/5 classes tested (i. e., alkylating agents, anti-metabolites, anti-tumor anti-biotics, and topoisomerase inhibitors) in ≥2 databases (Fig 2 and Table 2). This evidence concerns the gene SLFN11 and neoplasm.
