Potential functions of long non‑coding RNAs in the osteogenic differentiation of human bone marrow mesenchymal stem cells.

Long non‑coding RNAs (lncRNAs) are a specific group of RNA molecules that do not encode proteins. They have been shown to serve important regulatory functions in various biological and cell differentiation processes. However, the potential functions and regulatory mechanisms of lncRNAs that are associated with the osteogenic differentiation of human bone marrow mesenchymal stem cells (hBMSCs) remain to be elucidated.

[Effect of macrophage inflammatory protein-1β on proliferation and apoptosis of human tongue squamous cell carcinoma CAL-27 cells in vitro].

Objective: To detect CCR5 protein expression in different human tongue squamous cell carcinoma cells and observe the effect of macrophage inflammatory protein-1β (MIP-1β) on the proliferation and apoptosis of CAL-27 cells.

Methods: Western blotting and immunofluorescence staining were used to detect the expression of the CCR5, the receptor of MIP-1β, in 3 human tongue squamous cell carcinoma cells UM-1, CAL-27, and Tca-8113. CCK-8 assay was used to assess the proliferation of CAL-27 cells stimulated with 10, 20, and 40 ng/mL MIP-1β for 12, 24, or 48 h.

[Synovial chondromatosis in the temporomandibular joint: analysis of 5 cases].

Five patients with synovial chondromatosis in the temporomandibular joint were treated in our hospital between August, 2011 and August, 2014. All the patients underwent preoperative imaging examinations for clinical diagnosis and determining the involvement of the lesions. Surgeries were performed and the lesions were confirmed as synovial chondromatosis by pathological diagnosis.
