At present, cancer is one of the greatest threats to mankind, and is associated with the highest rates of morbidity and comorbidity. Recently, the advancements in molecular biology have led to an in-depth understanding of the underlying pathophysiology, which may further impact the lead time in the context of early discovery and effective therapy of cancer. Therefore, the present study proposes a better understanding of the role of micro(miR)-425-5p in diffuse large B-cell lymphoma (DLBC).
qRT-PCR was carried out to detect the relevant proteins, miRNA and mRNA RNA gene expression in DLBC cells. The effect of miR-425-5p on DLBC growth was examined by CCK-8 and colony formation assays. The binding relationship between genes was verified by dual-luciferase reporter gene assay.
We demonstrated how the over-expression of miR-425-5p can lead to increased progression of DLBC by increasing the cellular proliferation rate and colony-forming ability. Additionally, we also found that the expression of miR-425-5p could be significantly inhibited on the basis of phosphatase and tensin homolog (PTEN) signaling pathways.
The present study concludes that miR-425-5p is responsible for the oncogenic progression and relapse of DLBC tumorigenesis via PTEN/PI3K signaling, which can thus be effectively used to achieve better therapeutic outcomes.
目前,癌症是对人类最大的威胁之一,且发病率和合并症发生率极高。近年来,分子生物学的进展使人们对潜在的病理生理学有了更深入的了解,这可能会进一步影响癌症早期发现和有效治疗的提前期。因此,本研究旨在更好地了解微小RNA(miR)-425-5p在弥漫性大B细胞淋巴瘤(DLBC)中的作用。
采用qRT-PCR检测DLBC细胞中相关蛋白质、miRNA和mRNA基因的表达。通过CCK-8和集落形成实验检测miR-425-5p对DLBC生长的影响。采用双荧光素酶报告基因实验验证基因之间的结合关系。
我们证明了miR-425-5p的过表达如何通过提高细胞增殖率和集落形成能力导致DLBC进展加快。此外,我们还发现,在磷酸酶和张力蛋白同源物(PTEN)信号通路的基础上,miR-425-5p的表达可被显著抑制。
本研究得出结论,miR-425-5p通过PTEN/PI3K信号通路导致DLBC肿瘤发生的致癌进展和复发,因此可有效地用于实现更好的治疗效果。
