As part of a study on the selective loss of large CFS genes in cancer, McAvoy et al. showed that DMD expression (by qRT-PCR using primers in the 3’-untranslated region) is reduced in all brain tumour cell lines tested, as well as in a xenograft derived from an intracranial model of glioblastoma (GBM) [3]. The gene discussed is DMD; the disease is brain neoplasm.
