Recombinant Human Heat shock protein beta-8 (HSPB8)

1. results strongly suggest that HSP22 represses HCC progression, especially HCC cell migration, by the down-regulation of the PI3K/AKT signaling pathway. PMID: 28456666
2. Data indicated that the HSPB8 expression level was strongly positively correlated with MAPK signaling pathway and CREB pathway and worse prognosis.
