MicroARNAs (miRNAs) are linked to a variety of cancers, which resulted in molecular pathway dysregulation in chronic lymphocytic leukemia (CLL). Using five dysregulated miRNAs identified by literature mining and in silico analysis, we were able to demonstrate the critical role that the TGFBR1 and TGFB receptor signaling pathways play in the state of CLL. Assays using real-time PCR were run on 30 patients and 30 healthy controls. This study showed that patient samples have considerably higher levels of miR-574 and miR-499. Notably, the same groups had lower expression levels of miR-125b, miR-106a, and miR-9. Furthermore, we suggested that TGFBR1 and TGFBR2 expression levels were decreased in patients, and we suggested that these genes could be targets for our profile miRNAs. In the current study, we hypothesized that miR-574, miR-499, miR-125b, miR-106a, and miR-9 are likely five new potential biomarkers for early diagnosis. Our research also showed that these profile miRNAs have a role in the formation of CLL, possibly through controlling the TGFBR1 and TGFBR2 pathways. This suggests that these profile miRNAs could serve as biomarkers for the diagnosis and prognosis of CLL.
