Abstract miR-152, as a tumor suppressor, has been reported to be downregulated in a number of cancer cell lines and tumor tissues, including breast cancer. This study aimed to investigate the role of miR-152 in human breast cancer and its underlying mechanisms. Human breast cancer cell line HCC1806 was transfected with hsa-miR- 152-3p mimic, inhibitor, or scrambled negative controls. The efficiency of miR-152-3p transfection was evaluated by quantitative real-time PCR, and the effects on cell viability and apoptosis as well as on the PI3K/AKT signaling pathway were investigated by MTT assay, flow cytometry, and Western blot… More >

Abstract miR-152 and lncRNA H19 have been frequently implicated in various cellular processes including cell proliferation, invasion, angiogenesis, and apoptosis. However, the interaction between miR-152 and H19 in glioma has never been reported. RT-qPCR was used to examine the expression of miR-152 and H19 in human glioma cell lines and normal human astrocytes (NHAs). The interaction between miR-152 and lncRNA H19 was assessed by dual-luciferase reporter assay. MTT assay and Transwell invasion assay were used to determine the proliferation and invasion of U251 and U87 cells. A xenograft tumor experiment was performed to confirm the role… More >

Abstract MicroRNA-152 (miR-152) expression has been reported to be downregulated in osteosarcoma (OS). However, the role of miR-152 in OS is not well documented. In the present study, we aimed to explore the function and underlying mechanism of miR-152 in OS. We found that miR-152 was underexpressed in OS tissues and cell lines. Decreased miR-152 was inversely correlated with lymph node metastasis and advanced clinical stage. Overexpression of miR-152 significantly inhibited cell proliferation, colony formation, migration, and invasion of OS cells. Bioinformatics analyses showed that miR-152 directly targeted E2F transcription factor 3 (E2F3), as further confirmed More >

Abstract Aberrant expression of microRNA-152 (miR-152) is frequently observed in human cancers including ovarian cancer, breast cancer, prostate cancer, and gastric cancer. However, its expression and functional role in cervical cancer (CC) are poorly understood. Also, the association between miR-152 and Krüppel-like factor 5 (KLF5) expression in CC remains unclear. In this study, analyzing the expression of miR-152 by quantitative real-time PCR (qRT-PCR) revealed it was sharply reduced in CC tissues and cell lines. In addition, the negative correlation of miR-152 expression and KLF5 expression was observed. The dual-luciferase reporter assay validated that KLF5 was a More >

Abstract To investigate the expression and clinical significance of miR-152 and CYFRA21-1 in ovarian cancer (OC) tissues. Seventy-four OC patients diagnosed in our hospital from March 2016 to April 2019 (research group, RG) and 30 patients with benign ovarian tumor at the same time (control group, CG) were collected as research objects in this experiment. qRT-PCR and ELISA were used to detect and observe the expression levels of miR-152 in patient tissues and CYFRA21-1 in serum. ROC curves were drawn to analyze the diagnostic value of miR-152 and CYFRA21-1 in OC. The clinicopathological correlation analysis was… More >
