Leukemia-Related Signaling Pathways Among HTLV-1-Derived Adult T Cell Leukemia/Lymphoma and Asymptomatic Carriers in Comparison to Normal Group.

Human T cell lymphotropic virus type 1 (HTLV-1) is associated with adult T cell leukemia/lymphoma (ATLL), a fetal malignant infection. Recently, HTLV-1 new asymptomatic carriers (ACs) have frequently been reported among blood donors. Reaching the profound concept of HTLV-1-associated molecular pathogenesis could result in finding novel therapeutic strategies. The current study aimed to determine leukemia-related signaling regulation in ATLL. Thirty participants were evaluated in 3 groups, including 10 ATLL patients, 10 ACs, and 10 normal controls. Blood samples were isolated without any chemotherapy history from ATLL patients. Also, blood samples were recovered from ACs and normal individuals. White blood cells isolation was done on the collected blood samples. After this, RNA was extracted from the prepared samples and used for the cDNA synthesis. and HTLV-1 basic leucine zipper factor as viral genes and cellular genes, including , , , , , , , and , were investigated using real-time PCR. The mean age of ATLL patients was 53.2 ± 7.32 years, and 9 (90%) were male. The and expression levels were significantly associated with ATLL patients compared with the internal control. However, the significant differences in expression of other genes in the remaining groups were not seen. Discovering viral and cellular signaling pathways that regulate HTLV-1 transformation is essential. A novel therapeutic strategy for ATLL-regulating cellular signaling pathways could be considered. Therefore, clinical trials using activators and inhibitors of related cellular signaling pathways for cell therapy of ATLL are recommended. It is recommended that more investigation be conducted on and to target these genes and reveal the molecular pathogenesis of ATLL.
