AKT2 is crucial for cancer cells' invasion, metastasis, and survival. It is a possible downstream gene target of cancer glycolysis-related microRNAs. The study investigated the role of miRNA-4716-3p, rs2304186, and the AKT2 gene in blood cancer pathogenesis. RT-qPCR was used to analyze AKT2 gene mRNA and miRNA-4716-3p expression in 200 blood cancer samples and 200 healthy controls. Furthermore, Tetra-ARMS PCR was used to examine the rs2304186 AKT2 SNP in 300 patients and 290 control samples. miRNA-4716-3p was shown to be significantly downregulated (p = 0.0294), whereas mRNA expression of the AKT2 gene was found to be significantly upregulated (p = 0.0034) in blood cancer patients compared to healthy individuals. miRNA-4716-3p downregulation (p = 0.0466) was more pronounced, while AKT2 upregulation was non-significant (p = 0.1661) in untreated patients compared to chemotherapy-treated patients. Blood cancer risk was significantly associated with the rs2304186 GT genotype (p = 0.0432), TT genotype (p = 0.0502), and mutant allele (T) frequency (p = 0.0008). Polymorphism rs2304186 was associated with an increased risk of blood cancer in dominant (p = 0.0011), recessive (p = 0.0502), and additive (p = 0.0008) genetic models. The results suggested that the rs2304186 and the deregulated expression of miRNA-4716-3p and AKT2 gene at the mRNA level may significantly increase the incidence of blood cancer, particularly in the Pakistani population. Therefore, these may function as suitable biomarkers for blood cancer diagnosis and prognosis. Additional, larger-scale investigations may be required to affirm these results.
AKT2对癌细胞的侵袭、转移和存活至关重要。它是癌症糖酵解相关微小RNA可能的下游基因靶点。该研究调查了miRNA - 4716 - 3p、rs2304186和AKT2基因在血癌发病机制中的作用。采用逆转录定量聚合酶链反应(RT - qPCR)分析200份血癌样本和200份健康对照中AKT2基因mRNA和miRNA - 4716 - 3p的表达。此外,采用四引物扩增受阻突变系统聚合酶链反应(Tetra - ARMS PCR)检测300例患者和290份对照样本中的rs2304186 AKT2单核苷酸多态性(SNP)。结果显示,与健康个体相比,血癌患者中miRNA - 4716 - 3p显著下调(p = 0.0294),而AKT2基因的mRNA表达显著上调(p = 0.0034)。与化疗治疗的患者相比,未治疗患者中miRNA - 4716 - 3p下调更明显(p = 0.0466),而AKT2上调不显著(p = 0.1661)。血癌风险与rs2304186的GT基因型(p = 0.0432)、TT基因型(p = 0.0502)以及突变等位基因(T)频率(p = 0.0008)显著相关。在显性(p = 0.0011)、隐性(p = 0.0502)和加性(p = 0.0008)遗传模型中,多态性rs2304186与血癌风险增加相关。结果表明,rs2304186以及miRNA - 4716 - 3p和AKT2基因在mRNA水平的表达失调可能显著增加血癌的发病率,尤其是在巴基斯坦人群中。因此,这些可能作为血癌诊断和预后的合适生物标志物。可能需要进一步开展更大规模的研究来证实这些结果。
