Plotting CR vs. septin 7 levels of all tested cell lines revealed a clear clustering: epithelioid MM (ZL55, ZL5, JL1 and H226) and biphasic MM cells with a major part of epithelioid cells (MSTO-211H) formed the group of high CR-expressing cells (Fig. 4b). The gene discussed is CALB2; the disease is Miyoshi myopathy.
