The gradually increasing incidence rate of brain metastasis in lung cancer seriously affects patients quality of life and leads to poor prognosis [1, 2]. Our data suggest that astrocytes in primary culture can sustainably proliferate when their energy metabolism relies only on aerobic glycolysis since their growth and survival do not require electron flux through respiratory complex I or oxidative phosphorylation.

We conclude that methods based on the use of SV40 T antigen can successfully immortalize human astrocytes, retaining key astrocyte functions, but T antigen-induced proliferation appeared to interfere with expression of glial fibrillary acidic protein. Reports have shown that tumor-cell-derived exosomes could regulate the metabolism of niche cells in specific organs and contribute to PMN formation [30]. Label-free quantitative proteomics was used to analyze the differentially expressed proteins. Fong and his colleagues demonstrated that uptake of miR-122-containing exosomes secreted by breast cancer cells leads to decreased expression of PKM2 and GLUT1 in astrocytes and reduced glucose ingestion [32]. The cells were digested with EDTA-free trypsin, centrifuged at 1000g for 5min, then re-suspended with 1ml PBS and counted. Western Blot showed that the extracted exosome-positive protein markers CD9, Tsg101, and CD63 were expressed, while the negative-protein marker Calnexin did not expressed (Fig. Front Mol Neurosci. sharing sensitive information, make sure youre on a federal Exosomes of H1299 could induce apoptosis of astrocytes as well as promote their secretion of cytokines that were conducive to the formation of the inflammatory microenvironment and immunosuppressive microenvironment, and affect their metabolic pathways, thus facilitating the formation of pre-metastatic niche in lung cancer brain metastases. Biology (Basel). WebPrimary human astrocytes were transfected with the SV40 T antigen expression vectors, pSV3neo or p735.6, and cultures were established with an extended lifespan. Not for human, clinical, diagnostic or veterinary use. Decontaminate the bottle with 70% alcohol in a sterile hood.

Astrocyte dysfunction is considered one of the pathological causes of many diseases including trauma, stroke and multiple sclerosis. Next, 1ml trypsin solution was added, and the cells were incubated in the incubator for 3min until they fell off and separated from the culture bottle wall. Here, we report the establishment of a new human astrocyte cell line, HASTR/ci35, which show various key astrocyte properties, including astrocytic transporter activities, glycogen storage and facilitation of neuronal cell differentiation.
