HSPB1 and neoplasm: Network analysis using IPA of the differentially expressed proteins in the diffuse subtype showed increased expression of proteins like HSPB1, KCTD, TPM3, PDLIM7, LUZP1, ACTN1, and CFL2; and decreased expression of proteins involved in the mitochondrial respiratory chain like NFU1, ACO2, PDHA1, and tumor suppressors like DECR1, CNDP2, and SPINT1 in the topmost network.
