Inhibition of STIM1 alleviates high glucose-induced proliferation and fibrosis by inducing autophagy in mesangial cells
In this study, we investigated the role of STIM1 in the proliferation and fibrosis in high glucose (HG)-induced HBZY-1 cells. We found that the expression of STIM1 was increased in renal tissues of diabetic rat and HBZY-1 cells stimulated by HG. Downregulation of STIM1-mediated SOCE suppressed hyperglycemic cell proliferation and fibrosis by activating autophagy. In addition, the inhibitory effect of downregulating STIM1 on cells was blocked by autophagy inhibitor Bafilomycin A1 (BafA1). Moreover, this experiment also showed that STIM1 regulated autophagy, cell proliferation and fibrosis via PI3K/AKT/mTOR signal pathway. T...

Biochem J. 2023 Sep 27;480(18):1445-1457. doi: 10.1042/BCJ20220309.ABSTRACTMulticellular organisms require carefully orchestrated communication between and within cell types and tissues, and many unicellular organisms also sense their context and environment, sometimes coordinating their responses. This review highlights contributions from chemical biology in discovering and probing mechanisms of cell-cell communication. We focus on chemical tools for labelling proteins in a cellular context and how these can be applied to decipher the target receptor of a signalling molecule, label a receptor of interest in situ to unders...

Biological activities of the aerial and undergound parts of < em > Gymnadenia nigra < /em > Rchb.f. (syn. < em > Nigritella nigra < /em > (L.) Rchb. f.) from the Italian Alps
This study investigated the bioactivity of both aerial (GNAR) and underground (GNUG) parts of Gymnadenia nigra Rchb.f. (syn. Nigritella nigra (L.) Rchb. f.) (Orchidaceae). The obtained data proved interesting when the samples were tested in two adrenocortical cancer cell lines (SW13 and H295R). In particular, the GNAR 80% methanol extract distinctly inhibited their viability after 24 h at a concentration of 1 µg/µL by MTT assay and trypan blue dye exclusion method. Cell morphology evaluation by means Wright's staining also showed significant results, particularly in SW13 cells under the effect of both extracts. GNAR extr...
