Opening a window to skin biomarkers for diabetes stage with optoacoustic mesoscopy
Light Sci Appl. 2023 Sep 18;12(1):231. doi: 10.1038/s41377-023-01275-3.ABSTRACTBeing the largest and most accessible organ of the human body, the skin could offer a window to diabetes-related complications on the microvasculature. However, skin microvasculature is typically assessed by histological analysis, which is not suited for applications to large populations or longitudinal studies. We introduce ultra-wideband raster-scan optoacoustic mesoscopy (RSOM) for precise, non-invasive assessment of diabetes-related changes in the dermal microvasculature and skin micro-anatomy, resolved with unprecedented sensitivity and det...

Signaling mechanism of growth hormone-releasing hormone receptor
Vitam Horm. 2023;123:1-26. doi: 10.1016/bs.vh.2023.06.004. Epub 2023 Jul 7.ABSTRACTThe hypothalamic peptide growth hormone-releasing hormone (GHRH) stimulates the secretion of growth hormone (GH) from the pituitary through binding and activation of the pituitary type of GHRH receptor (GHRH-R), which belongs to the family of G protein-coupled receptors with seven potential membrane-spanning domains. Splice variants of GHRH-Rs (SV) in human tumors and other extra pituitary tissues were identified and their cDNA was sequenced. Among the SVs, splice variant 1 (SV1) possesses the greatest similarity to the full-length GHRH-R an...

MiRNA a New Insight in Metabolic and Human Diseases: A Review
Cell Mol Biol (Noisy-le-grand). 2023 Aug 31;69(8):102-110. doi: 10.14715/cmb/2023.69.8.16.ABSTRACTThe purpose of this research is to examine existing studies on the association between microRNAs (miRNA) and age-related disorders. The miRNAs are small, noncoding RNA molecules with the ability to regulate gene expression. These are well-established in extracellular circulation, including various types of diseases such as cancer, cardiovascular diseases, and diabetes. Similarly, several miRNAs are associated with certain age-related conditions, such as increased miR-21 expression in cancer patients. Besides that, the miR-122 ...

Plant-derived cell-penetrating microprotein α-astratide aM1 targets Akt signaling and alleviates insulin resistance
Cell Mol Life Sci. 2023 Sep 16;80(10):293. doi: 10.1007/s00018-023-04937-y.ABSTRACTInsulin-resistant diabetes is a common metabolic disease with serious complications. Treatments directly addressing the underlying molecular mechanisms involving insulin resistance would be desirable. Our laboratory recently identified a proteolytic-resistant cystine-dense microprotein from huáng qí (Astragalus membranaceus) called α-astratide aM1, which shares high sequence homology to leginsulins. Here we show that aM1 is a cell-penetrating insulin mimetic, enters cells by endocytosis, and activates the PI3K/Akt signaling pathway indepe...

Evaluation of Willis Polygon Morphometry with Cranial Tomographic Angiography
CONCLUSION: We also found that the vessel diameters were similar in the HT, DM and HT+DM groups, and smaller than the control group. In addition, we think that knowing WP morphometric measurements will both guide the radio-anatomical evaluations to be made and increase the level of microanatomical knowledge in surgical treatment.PMID:37715602 | DOI:10.5137/1019-5149.JTN.40346-22.4

Bioinformatics-based analysis of core genes and pathway enrichment in early diabetic nephropathy
Cell Mol Biol (Noisy-le-grand). 2023 Jul 31;69(7):51-56. doi: 10.14715/cmb/2023.69.7.9.ABSTRACTDiabetic nephropathy (DN) is the main cause of end-stage renal disease (ESRD). Bioinformatics technology was adopted to screen and analyze the core genes of early DN to explore its pathogenesis. GSE30528, GSE96804, and GSE30122 chip data were obtained from Gene Expression Omnibus (GEO) database to screen DN and healthy controls for differentially expressed genes. Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG) for functional annotation and signaling pathway enrichment; String and Cytoscape were used for protein...
