Abstract

MicroRNA-128 (miR-128) serves as a regulator by inducing cancer cell apoptosis, differentiation, the epithelial-to-mesenchymal transition process, and tumor growth by mediating different targets. NIMA-related kinase 2 (NEK2) is aberrantly expressed in lung cancer. The miR-128/NEK2 pathway has been reported to predict prognosis in colorectal cancer; however, the determination of a relationship between miR-128 and NEK2 in lung cancer has remained elusive. We explored the association between miR-128 and NEK2 in lung cancer. MiR-128 and NEK2 expression were examined in 15 lung cancer tissues by real time-PCR. Lung cancer SK-MES-1 cells were transfected with miR-128 mimic, an inhibitor or a negative control. MiR-128 and NEK2 expression levels were detected using quantitative real time-PCR and Western blot. SK-MES-1 cell apoptosis was performed by flow cytometry. Compared to adjacent non-tumor tissues, miR-128 was downregulated and NEK2 was upregulated in 15 lung cancer tissues. Lung cancer SK-MES-1 cells transfected with miR-128 mimic induced a higher apoptotic rate than those transfected with the negative control. Dual luciferase assay further confirmed that NEK2 was a direct target of miR-128 in lung cancer, and transfection with ...Continue Reading

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis

Apoptosis in Cancer

Apoptosis is an important mechanism in cancer. By evading apoptosis, tumors can continue to grow without regulation and metastasize systemically. Many therapies are evaluating the use of pro-apoptotic activation to eliminate cancer growth. Here is the latest research on apoptosis in cancer.
