HSPA6 and glioma: While investigating potential prognostic markers for human glioma, Sun et al. (Sun et al., 2020a) constructed a protein-protein interaction (PPI) network and found that nine heat shock proteins (DNAJA4, DNAJC6, DNAJC12, HSPA6, HSP90B1, DNAJB1, DNAJB6, DNAJC10, and SERPINH1) were differentially expressed; of these, only HSPA6 belonged to the HSP70 family.
