CD30, also known as TNFRSF8, is a cell membrane protein of the tumor necrosis factor receptor family and tumor marker.D30 is associated with anaplastic large cell lymphoma. It is expressed in embryonal carcinoma but not in seminoma and is thus a useful marker in distinguishing between these germ cell tumors. CD30 and CD15 are also expressed on classical Hodgkin Lymphoma Reed-Sternberg cells.
1 It was found that CD44 (a cell surface marker for cancer stem cells) interacts with pyruvate kinase M2 and thereby enhances the glycolytic phenotype of cancer cells that are either deficient in p53 or exposed to hypoxia. The CD44 gene is silenced in NB4 acute promyelocytic leukemia cells by DNA methylation of a CpG island & underacetylation of histone H3 at the promoter. 2  Brahma protein & phosphorylated RNA Pol II interact with the promoter region of CD44.
