Candidate Regulatory Relationship and Expression Correlation Between miR-33a-5p and ANK3 in Chronic Myeloid Leukemia

Chronic myeloid leukemia (CML) is a type of bone marrow cancer characterized by the uncontrolled proliferation of myeloid cells. MicroRNAs (miRNAs) are small, non-coding RNA molecules that play a crucial role in the post-transcriptional regulation of gene expression. This study aims to examine the association between miR-33a-5p and Ankyrin 3 (ANK3) in CML and to investigate the regulatory mechanisms of miR-33a-5p in the progression of this disease. mRNA expression profiles were obtained from the GSE100026 dataset within the Gene Expression Omnibus (GEO) repository. Quantitative real-time polymerase chain reaction (RT-qPCR) was conducted to assess the expression levels of miR-33a-5p and ANK3. To investigate the regulatory mechanism of miR-33a-5p/ANK3, various databases such as miRNet, miRDIP, TargetScan, BioGRID, and CancerSEA were utilized. The expression of miR-33a-5p was markedly elevated, while ANK3 expression was significantly reduced. Furthermore, pathway clustering and functional assessments of ANK3 demonstrated its involvement in regulating the cell cycle and apoptosis. The findings identify an inverse expression pattern between miR-33a-5p and ANK3 across the two cell models and support a candidate regulatory relationship that warrants direct functional validation. This relationship may merit further investigation as a potential molecular target in CML.
