Changes in gene expression after epigentic targeted therapy in T-cell prolymphocytic leukemia (T-PLL). Homo sapiens

Epigenetic therapy overcame alemtuzumab resistance in patients with relapsed T-cell prolymphocytic leukemia and induced the expression of treatment related genes. Method: patient PBMCs from Ficoll, normal patient PBMCS enriched for CD3+/CD8+ or CD3+/CD8+/CD45RA+/CCR7- were extracted in Trizol. Conclusion: Gene expression profiles were changed by epigenetic therapy, likely activating treatment response genes silenced by carcinogenesis. Overall design: Total RNA from patient Peripheral Blood Mononuclear Cells (PBMC) or from normal negatively enriched CD3+/CD8+/CCR7-/CD45RA+(CD45RO-) blood
