CLSPN and cancer: Our study probed the potential correlation between CLSPN expression and IC50 values of anti-cancer compounds in different human cancer cell lines, and found out that CLSPN expression was positively associated with drug sensitivity of PF − 06463922, salinomycin, KU − 55933, Olaparib, AZD − 3463, etc. and negatively correlated with drug sensitivity of Birinapant, 6 − Thioguanine, 6 − THIOGUANIN, Nelarabine.
