Abstract Background: Receptor tyrosine kinase-like orphan receptor 2 (ROR2) has a vital role in osteogenesis. However, the mechanism underlying the regulation of ROR2 in osteogenic differentiation is still poorly comprehended. A previous study by our research group showed that a novel compound heterozygous ROR2 variation accounted for the autosomal recessive Robinow syndrome (ARRS). This study attempted to explore the impact of the ROR2: c.904C>T variant specifically on the osteogenic differentiation of BMSCs. Methods: Coimmunoprecipitation (CoIP)-western blotting was carried out to identify the interaction between ROR2 and Wnt5a. Double-immunofluorescence staining was used for determining the expressions and co-localization of ROR2 and Wnt5a… More > Graphic Abstract

Abstract Glioma is one of the lethal central nervous system tumors. The infiltrative and invasive growth nature makes it difficult to identify the boundary between glioma and the normal tissues, resulting in inevitable recurrence after surgery operation. Gliomas do not metastasize, so to prevent the residual tumor from proliferating or invading is a key challenge. Previous report indicated that hypotaurine could facilitate glioma invasion and suppress demethylases’ activities. Using a hypotaurine synthesis deficient U251 cell line, we proved that the cells invasion ability was impaired. Gene expression profile analysis exhibited that knocking down one of the key enzymes of hypotaurine synthesis,… More >
