The involvement of Sestrin2 in the effect of IGF-I and leucine on mTROC1 activity in C2C12 and L6 myocytes
CONCLUSIONS: IGF-I and leucine cooperatively increased mTORC1 activity in C2C12 cells. IGF-I increased Sestrin2. Sestrin2 siRNA experiments showed that Sestrin2 was involved in the effect of leucine and IGF-I on mTORC1 activity in C2C12 and L6 cells, and suggested that increased Sestrin2 by IGF-I pretreatment might play a role in enhancing the effect of leucine on mTORC1.PMID:34126555 | DOI:10.1016/j.ghir.2021.101406

Effect of anti-M üllerian hormone on the regulation of pituitary gonadotropin subunit expression: roles of kisspeptin and its receptors in gonadotroph LβT2 cells
In this study, we examined the effect of AMH on pituitary gonadotrophs. We detected AMH and AMH receptor type 2 expression in LβT2 cells. In these cells, the expression of FSHβ- but not α- and LHβ-subunits increased significantly as the concentration of AMH increased. LβT2 cells expressed Kiss-1 and Kiss-1R. AMH stimulation resulted in decreases in both Kiss-1 and Kiss-1R. The siRNA-mediated knockdown of Kiss-1 in LβT2 cells did not alter the basal expression levels of α-, LHβ-, and FSHβ-subunits. In LβT2 cells overexpressing Kiss-1R, exogenous kisspeptin stimulation significantly increased the expression of all ...

Mass Spectrometry Imaging Identifies Metabolic Patterns Associated with Malignant Potential in Pheochromocytoma and Paraganglioma
CONCLUSIONS: The present study has identified distinct tissue metabolomic profiles of PPGLs in relation to tumor genotypes. In addition, we revealed significantly altered metabolites in the kynurenine pathway in metastatic PPGLs, which can aid in the prediction of its malignant potential. However, further validation studies will be required to confirm our findings.PMID:33983135 | DOI:10.1530/EJE-20-1407

An RNAi screening of clinically relevant transcription factors regulating human adipogenesis and adipocyte metabolism
CONCLUSIONS: This comprehensive RNAi screening in hASC suggests that a large proportion of WAT TFs that are impacted by metabolic conditions might be important for hyperplastic adipose tissue expansion. The screen also identified JARID2 as a novel TF essential for the development of functional adipocytes.PMID:33963396 | DOI:10.1210/endocr/bqab096

Insulin receptor substrate 1 gene expression is strongly up-regulated by HSPB8 silencing in U87 glioma cells
Conclusions. Results of this investigation demonstrated that silencing of HSPB8 mRNA affected the expression of IRS1 gene as well as many other genes encoding tumor growth related proteins. It is possible that the dysregulation of most of the studied genes in glioma cells after silencing of HSPB8 is reflected by a complex of intergenic interactions and that this polyfunctional chaperone is an important factor for the stability of genome function and regulatory mechanisms contributing to the tumorigenesis control.PMID:33885248 | DOI:10.2478/enr-2020-0026
