Analysis of gene expression and ChIP-seq in published cell line and/or primary DLBCL datasets.<h4>Results</h4>We show that some BCL6<sup>hi</sup> GC-DLBCL cell lines express low levels of VDR, but appear resistant to VitD3, and associate VDR positivity in both GC- and ABC-DLBCL cell lines with the poor prognosis plasmacytic/activation marker CD38. This evidence concerns the gene CD38 and diffuse large B-cell lymphoma.
