Conclusion
In the present study notable depletion of survivality was established in the Imatinib resistance patients manifesting genetic malfunction of BCR-ABL transcripts among the North East Indian inhabitants and advocating for the expansion of the disease.
Methods
The Imatinib resistance was screened through RFLP. In this case maximum number of patients were recorded in the chronic phase belonging to the age group 40-59 and the accelerated and blast phase is more common in elderly patients showing the progressive nature of the disease with age. Hemoglobin and platelet count are found to be higher in cases where WBC count was minimal. A history of long-term alcohol consumption is found to be associated with the progression of the disease.
Objective
Changes in the methylation status of genes may impart to the advancement of Chronic Myeloid Leukaemia. The present investigation aims to assess the role of expression analysis and methylation status of DDIT3 and MGMT genes in imatinib-resistant and nonresistant cases.
Results
The maximum level of expression of the DDIT3 gene was recorded in the chronic phase regardless of upstream (67.8%) and downstream (57.9%) regulation. The highest MGMT expression regulation was also observed in the case of chronic phase in both upstream (78.9%) and downstream (44%) regulation. Further, the MGMT gene showed the highest methylation of 6.6% and DDIT3 showed 3.3% in CML cases.
