    miR-101 Represses T-Cell Acute Lymphoblastic Leukemia by Targeting CXCR7/STAT3 Axis

    Xue-Yi Yang, Ye Sheng

    Oncology Research, Vol.27, No.9, pp. 997-1006, 2019, DOI:10.3727/096504018X15439207752093

    Abstract Although miR-101 is involved in the development and progression of T-cell acute lymphoblastic leukemia (T-ALL), the underlying molecular mechanisms remain unclear. In this article, we report that miR-101 expression was inversely correlated with CX chemokine receptor 7 (CXCR7) level in T-ALL. Introducing miR-101 inhibited T-ALL cell proliferation and invasion in vitro and suppressed tumor growth and lung metastasis in vivo. CXCR7 was identified as a direct target of miR-101. The inhibitory effects of miR-101 were mimicked and counteracted by CXCR7 depletion and overexpression, respectively. Mechanistically, miR-101 targets CXCR7/STAT3 axis to reduce T-ALL growth and metastasis. Overall, these findings implied the… More >

    MicroRNA-101 Targets CXCL12-Mediated Akt and Snail Signaling Pathways to Inhibit Cellular Proliferation and Invasion in Papillary Thyroid Carcinoma

    Fang Chen*, Dongqiang Yang, Yuhua Ru, Shan Cao*, Aishe Gao*

    Oncology Research, Vol.27, No.6, pp. 691-701, 2019, DOI:10.3727/096504018X15426763753594

    Abstract Escalating evidence suggests that microRNA-101 (miR-101) is implicated in the development and progression of various cancers, including papillary thyroid carcinoma (PTC). However, the biological function and molecular mechanisms of miR-101 in PTC are still unclear. In this study, we demonstrated that miR-101 expression was significantly decreased in PTC tissues and cell lines. Clinically, a low level of miR-101 was positively associated with advanced histological stages and lymph node and distant metastases. The expression of CXCL12 was negatively correlated with miR-101 level in PTC. CXCL12 was validated as a direct target of miR-101 in PTC cells. Functional experiments proved that miR-101… More >

    miRNA-101 Targets TGF-bR1 to Retard the Progression of Oral Squamous Cell Carcinoma

    Yong Wang*, Rui-Zhi Jia*, Shu Diao*, Jun He, Li Jia

    Oncology Research, Vol.28, No.2, pp. 203-212, 2020, DOI:10.3727/096504019X15761480623959

    Abstract Despite the considerable knowledge on the involvement of microRNA-101 (miR-101) in the evolution of oral squamous cell carcinoma (OSCC), the underlying mechanisms remain obscure. In this study, miR-101 expression was markedly downregulated in the OSCC cell lines and tissues. Cell counting kit-8 (CCK-8), ethynyl deoxyuridine (EdU), and colony formation assays showed that miR-101 inhibited the proliferation of OSCC cells. Flow cytometry and caspase 3 activity assays indicated that miR-101 induced OSCC cell apoptosis. Transwell assays demonstrated that this miRNA also repressed OSCC cell migration and invasion. Moreover, tube formation assay showed that miR-101 abated the proangiogenesis of OSCC cells. Dual-luciferase… More >
