Circulating factors present in the sera of naturally skinny people may influence cell commitment and adipocyte differentiation of mesenchymal stromal cells

World Journal of Stem Cells 2019年第3期11卷 180-195页

BACKGROUND Research on physiopathology of obesity may receive new hints from studies on skinny people(SP). These are individuals who show a poor or null gaining of body weight, in spite of high-calorie intake, by far exceeding the body *** To evaluate how circulating factors present in the SP sera may affect adipogenesis of mesenchymal stromal cells(MSCs).METHODS We isolated MSCs from bone marrow of healthy donors with both normal body mass index(BMI) and caloric consumption. MSC cultures were primed with sera collected from SP or normal people(NP). Then biomolecular assays were performed to evaluate effect on proliferation, apoptosis, senescence, cell commitment, and *** SP priming affected adipocyte cell commitment and reduced spontaneous adipogenesis. Moreover, an in-depth analysis of exogenous-induced adipocyte differentiation showed striking differences between differentiation in SP-primed samples compared with NP ones. In adipocytes from SP cultures we observed a reduced size of lipid droplets, an increased expression of adipose triglyceride lipase, along with high mitochondria content and ability to produce ATP in starvation condition. These data and the expression of UCP1 protein, indicated that SP pretreatment produced a bias toward brown adipocyte *** Our data suggest that sera from SP may promote brown adipogenesis rather that white adipocyte differentiation. This finding could explain why SP present normal body composition in spite of an excess of caloric intake. We hypothesize that some circulating components present in the blood of these individuals may favor brown adipogenesis at expense of white adipocyte production.

To the Editor:Hepatocellular carcinoma (HCC) is the most common primary livertumorandthethirdcauseofcancer-relateddeathsworldwide. HCC is the consequence of malignant transformation of hepatocytes and mainly occurs in patients with cirrhosis. Hepatitis C virus (HCV) chronic infection is a leading cause of end-stage liver diseaseandHCCintheWesterncountries[1].Theapprovalof direct-acting antiviral agents (DAAs) for the treatment of HCV has revolutionized the management of the disease, as no absolute contraindication to treatment exists and sustained virological response

Is there a relationship between dopamine and rhegmatogenous retinal detachment?

Neural Regeneration Research 2020年第2期15卷 311-314页

Dopamine and its receptors have been widely studied in the neurological conditions and in the retina. In this study, we evaluated the possible role of dopamine in rhegmatogenous retinal detachment(RRD) by comparing the amount of 3,4-dihydroxyphenylacetic acid(DOPAC), a surrogate index of retinal dopamin levels, in the vitreous sample of patients affected by RRD with those affected by macular pucker and vitre ous hemorrhage. Our results showed that significantly higher levels of DOPAC were found in the vitreou sample of patients affected by RRD compared with those affected by vitreous hemorrhage and macula pucker(P = 0.002). Specifically, no trace of the substance was found in vitreous hemorrhage and macula pucker samples. A slightly significant positive correlation was found among DOPAC and post-operativ best corrected visual acuity(r = 0.470, P = 0.049). No correlation was found between DOPAC and the day elapsed between diagnosis and surgery(P = 0.317). For the first time our findings suggest that DOPAC i released in RRD, but not in other retinal diseases such as vitreous hemorrhage and macular pucker. More over, we showed a correlation between visual acuity outcome and the amount of DOPAC in the vitreous This might have a potential, although still unknown, implication in the pathogenesis of the disease and/o in the associated photoreceptors loss. This study was approved by the Ethics Committee of Rome Tor Ver gata University Hospital(R.S.92.10) on September 24, 2010.
