FGF21 as Modulator of Metabolism in Health and Disease
In conclusion, FGF21 belongs to a promising class of cytokines that are induced in response to stress and that can be used as a drug, drug target, or through a biomarker, depending on the physio-pathological context. All these findings will become clear when FGF21 will be used as a therapeutic molecule, exploiting the beneficial effects of FGF21 for treating metabolic disease or when it will be blocked to ameliorate disease progression and the onset of disease.

Gold nanorod delivery of LSD1 siRNA induces human mesenchymal stem cell differentiation.
In this study, we have developed poly-sodium 4-styrenesulfonate (PSS) and poly-allylamine hydrochloride (PAH) coated AuNR-based nanocarriers, which are capable of delivering small interfering RNA (siRNA) against LSD1 to induce the differentiation of human mesenchymal stem cells. To further study the mechanism, we tested the stemness and differentiation genes and found that they have been changed with LSD1 down-regulation. In addition, with the hepatocyte growth factor (HGF), LSD1 siRNA delivery by AuNRs could promote the differentiation of the human mesenchymal stem cells (human MSCs) into a hepatocyte lineage in vitro. Ou...

Caveolin-1 upregulation in diabetic fibroblasts and wounded tissues: implication for understanding the underlying mechanisms of non-healing diabetic ulcers.
Abstract A heightened state of oxidative stress and senescence of fibroblasts constitute potential therapeutic targets in non-healing diabetic wounds. Here, we studied the underlying mechanism mediating diabetes-induced cellular senescence using in vitro cultured dermal fibroblasts and in vivo circular wounds. Our results demonstrated that the total antioxidant capacity, mRNA levels of thioredoxinreductase and glucose-6-phosphate dehydrogenase as well as the ratio of NADPH/NADP were markedly decreased in fibroblasts from patients with type 2 diabetes (DFs). Consistent with this shifts in favor of excessive reactiv...
