In our series, 5 HSPs were deregulated (HSPA12A: 3.31-fold, p=4.34e-4; HSPA13: 2.54-fold, p=0.0035; HSPA4L: 2.38-fold, p=1.17e-4; HSPB6: −2.19-fold, p=5.76e-4; HSPB8: −3.77-fold, p=0.001), suggesting that the CAV1/HSPs interaction may also play a role in schwannomas. Here, HSPA4L is linked to schwannoma.
