A computational study using data obtained from the Genomics of Drug Sensitivity in Cancer (GDSC) database reported that the expression levels of the four clock-associated genes BMAL1, NPAS2 (Neuronal PAS Domain Protein 2), DBP (D-Box Binding PAR BZIP Transcription Factor) and CRY2 correlated with the sensitivity of GBM to various drugs71,72. The gene discussed is CRY2; the disease is glioblastoma.
