Depending on our results, PRKCI, PRKCD, and PRKCZ associated-CNAs were driving their expressions in most cancers (except for PRKCI in DLBC, KICH, LAML, THCA, and THYM; PRKCD in GBM, HNSC, LAML, LGG, THYM, and UCS; and PRKCZ in ACC, GBM, KICH, LGG, THCA, THYM, and UCS). Here, PRKCZ is linked to glioblastoma.
