Fig. 8: Mechanisms at the basis of the antitumoral activity of HSPB8 in melanomas cell lines.

When expressed in melanoma cell lines, HSPB8 favors the unprenylated form of RAS over the prenylated form, inhibiting the RAF/MEK/ERK pathway, and facilitates autophagy. Therefore, HSPB8 exerts an antitumoral activity by inhibiting (i) the epithelial-mesenchymal transition (EMT)-like switching, (ii) migration, and (iii) proliferation.
