Audard et al. showed that the c-maf-inducing protein (c-mip) is selectively induced in both podocytes and HRS cells from patients presenting this association, but not in lymphomatous tissue from cHL patients without MCD, suggesting that the overexpression of c-mip in these cells may represent a molecular signature of the association (Figure 2) [44]. This evidence concerns the gene CMIP and classic Hodgkin lymphoma.
