Leukemia is a group of lethal diseases characterized by hematological neoplasm with complex and abnormalities in proliferation of bone marrow stem cells, that cause sever loss of functional capacity of hematopoietic tissue. Four most common types of leukemia are included acute lymphoblastic leukemia (ALL), acute myeloid leukemia (AML), chronic lymphocytic leukemia (CLL) and chronic myeloid leukemia (CML). It has been reported that opium besides of pain killer effects, may have positive effects on cardiovascular disease treatments. Opium may consider as a potential treatment method in cancer. The present study aimed to assess the gene expression pattern alterations in the rat models of four types of Leukemia (ALL, AML, CLL, and CML) under taper up-off treatment method with of opium.
Present study was included twelve group, referred to four type of Leukemia (ALL, AML, CLL, and CML) that each type studied in three group. Group one contented normal rats, group two rat model of each type of leukemia with no treatment and group three the rat model of that type of leukemia with 26 days period of opium taper up-off treatment. After the scarification of rats, the bone marrow tissue were extracted. Then, RNA extraction and cDNA synthesis had been conducted on bone marrow tissues. Whole genome expression profiling was conducted by using the Affymetrix GeneChip Array Platform. Microarray results were confirmed by Real time PCR. Microarray analysis detected that hundreds of genes which were involved in Ontogenesis and apoptosis, humoral immune system, tool like receptors, natural killer cells regulators and metabolic pathways and were deregulated in leukemic models, were partially reregulated in treatment groups. Results showed that opium may have positive effects on reregulation of affected gene expression patterns in all types of leukemia. It may suggest that opium taper up-off treatment could be consider as re-regulator of immune system and a novel potential treatment for leukemia with low side effects and high viability.
