CAPN3 and melanoma: In order to over-express the Calpain-3 variant hMp84 (hereafter called p84) in human melanoma cells, preliminary experiments performed in a few cell lines were aimed to produce stably-transfected cells, through selection of neomycin-resistant clones; unfortunately, we failed to obtain stable p84 over-expressing cells, since they all died after 7–10 days of selection.
