    Recent studies highlight a prominent role of human lung pericytes in lung diseases. However, human lung pericytes usually stop growth within ten passages. This study successfully established an immortalized human lung pericyte cell line, which exhibited sustained proliferation, retained pericyte characteristics and function, is a promising tool for in vitro pericyte studies.

    In this study, the authors reveal that the hypoxic microenvironment stimulates glioma to generate miR-1246- and miR-10b-5p-rich exosomes, which are delivered to normoxic glioma cells to promote their migration and invasion by targeting FRK and TFAP2A respectively. Treatment targeting the exosomes and microRNAs may impair the motility of gliomas, providing a novel direction for the development of antitumor therapy.

    Tissue cytometry is a promising new microscopy technique that can be used to enumerate and characterize each cell in a tissue. Here the authors describe a complete and accessible pipeline, including methods of sample preparation, microscopy, image analysis, and data analysis for large-scale three-dimensional tissue cytometry of human kidney tissues.

    The abnormal differentiation of Th17 cells is a vital promoter of immune thrombocytopenia (ITP) progression. In this study, the authors found that miR-199a-5p is downregulated during ITP. Supplementation of extracellular vesicles (EVs) derived from miR-199a-5p-modified ADSCs markedly repress Th17 differentiation by transferring miR-199a-5p to CD4+T cells, thus ameliorating experimental ITP.

    This study confirms that the expression of GTSE1 in prostate cancer is significantly increased and negatively correlated with patient prognosis. Furthermore, GTSE1 promotes prostate cancer cell proliferation via the SP1/FOXM1 signaling pathway, which facilitates tumorigenesis and progression. These results suggest that GTSE1 has potential value as a prognostic marker and therapeutic target in prostate cancer.

    This study reveals that upregulation of lncRNA small nucleolar RNA host gene 5 (SNHG5), mediated by Yin Yang 1 (YY1), activates connective tissue growth factor (CTGF)/vascular endothelial growth factor (VEGFA) axis via targeting miR-26b to regulate angiogenesis of acute myelogenous leukemia (AML), providing new insights into mechanisms of AML.
