[PMID: 38395109 DOI: 10.1016/j.brainresbull.2024.110906] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2023] [Revised: 01/31/2024] [Accepted: 02/20/2024] [Indexed: 02/25/2024]
Abstract
OBJECTIVE To investigate the role of the striatal extracellular signal-regulated kinase (Erk1/2) and its phosphorylation (p-Erk1/2) in aerobic training to alleviate the development of the L-DOPA induced dyskinesia (LID) in PD mice. METHODS Forty-eight male C57BL/6 N mice were randomly divided into the 6-OHDA surgery group (6-OHDA, n=42) and the sham surgery group (Sham, n=6). A two-point injection of 6-OHDA into the right striatum was used to establish a lateralized injury PD model. PD mice were randomly divided into a PD control group (PD, n=13) and a PD exercise group (PDE, n=16), this is followed by 4 weeks of L-DOPA treatment, and PDE mice received concurrent running table training (18 m/min, 40 min/day, 5 times/week). AIM scores were performed weekly, and mice were assessed for motor function after 4 weeks using the rotarod, open field, and gait tests. Immunohistochemistry was used to test nigrostriatal TH expression, Western blot was used to determine Erk1/2 and p-Erk1/2 protein expression, and immunofluorescence double-labeling technique was used to detect Erk1/2 and p-Erk1/2 co-expression with prodynorphin (PDYN). RESULTS (1) All AIM scores of PD and PDE mice increased significantly (P < 0.05) with the prolongation of L-DOPA treatment. Compared with PD, all AIM scores were significantly lower in PDE mice (P < 0.05). (2) After 4 weeks, the motor function of PD mice was significantly reduced compared with Sham (P < 0.05 or P < 0.01); compared with PD, the motor function of PDE mice was significantly increased (P < 0.05). (3) Compared with Sham, the expression of Erk1/2 protein, the number of positive cells of Erk1/2 and p-Erk1/2 and the number of positive cells co-expressed with PDYN were significantly increased in PD mice (P < 0.05); compared with PD, Erk1/2 protein expression was significantly decreased in PDE mice (P < 0.05), and the number of Erk1/2 and p-Erk1/2 positive cells was significantly reduced (P < 0.05). CONCLUSION 4 weeks of aerobic exercise can effectively alleviate the development of L-DOPA-induced dyskinesia and improve motor function in PD mice. The related mechanism may be related to the inhibition of striatal Erk/MAPK signaling pathway overactivation by aerobic exercise, but this change did not occur selectively in D1-MSNs.

Abstract
Ischemic stroke is one of the major disabling health-care problem and multiple different approaches are needed to enhance rehabilitation, in which neural repair is the structural basement. Remote ischemic conditioning (RIC) is a strategy to trigger endogenous protect. RIC has been reported to play neuroprotective role in acute stage of stroke, but the effect of RIC on repair process remaining unclear. Several studies have discovered some overlapped mechanisms RIC and neural repair performs. This review provides a hypothesis that RIC is a potential therapeutic strategy on stroke rehabilitation by evaluating the existing evidence and puts forward some remaining questions to clarify and future researches to be performed in the field.

Abstract
Recently, three-dimensional (3D)-cultured adipose mesenchymal stem cells (ASCs)
have provided an effective therapy for liver fibrosis. This study aimed to
enhance the potential of human ASCs for antifibrosis or hepatocyte regeneration
using a 3D culture system and investigate their therapeutic mechanism in
experimental liver fibrosis. ASC-3Dc were generated in a 3D culture system and
stimulated with four growth factors, namely epidermal growth factor,
insulin-like growth factor (IGF)-1, fibroblast growth factor-2, and vascular
endothelial growth factor-A. The expression levels of antifibrotic or hepatic
regeneration factors were then measured using quantitative real-time polymerase
chain reaction and enzyme-linked immunosorbent assay. The therapeutic effects of
ASC-3Dc were determined using a liver fibrosis model induced by thioacetamide.
Histological analysis was performed to elucidate the therapeutic mechanism.
ASC-3Dc exhibited high levels of hepatocyte growth factor (HGF), IGF-1, stromal
cell-derived factor (SDF)-1 genes, and protein expression. In addition,
injecting ASC-3Dc significantly prevented hepatic fibrosis and improved liver
function in vivo. Moreover, high numbers of ki-67-expressing hepatocytes were
detected in the ASC-3Dc-injected livers. Albumin-expressing ASC-3Dc engrafted in
fibrotic livers augmented HGF expression. Thus, short-term 3D-cultured ASCs may
be a novel alternative to the conventional treatment for liver damage in
clinical settings.

Stem Cell Res Ther 2020; 11:332.

Abstract
BACKGROUND Cell therapy using hepatocytes derived from stem cells has been regarded as a promising alternate to liver transplantation. However, the heterogeneity of these hepatocytes makes them unsuitable for therapeutic use. To overcome this limitation, we generated homogenous hepatocyte like induced hepatocyte-like (iHep) cells. METHODS iHep cells were generated from induced pluripotent stem cells (iPSCs) integrated with the albumin (ALB) reporter gene. The therapeutic properties of these iHep cells were investigated after transplantation in fibrotic liver tissues of a mouse model. RESULTS The iHep cells expressed hepatocyte specific genes and proteins, and exhibited high levels of hepatocyte growth factor (HGF) and interleukin (IL)-10 expressions. Transplantation of iHep cells significantly decreased thioacetamide (TAA)-induced liver fibrosis, apoptotic cells in the liver, and ameliorated abnormal liver function. Liver tissues engrafted with iHep cells exhibited decreased expression of pro-inflammatory factors such as transforming growth factor (TGF)-β, IL-6, and monocyte chemo attractant protein (MCP)-1. Furthermore, an increased number of proliferating hepatocytes and human albumin-expressing iHep cells were detected in mice liver. CONCLUSIONS This study has investigated and proven the liver regeneration potential of genome-edited iHep cells and promises to be a strong foundation for further studies exploring cell therapy as an alternative therapeutic option for the treatment of liver fibrosis.

Abstract
Recently, reprogramming technology has emerged as a fascinating tool to generate specific tissue cells. In this study, we tested the hypothesis that ultrasound-directed cellular reprogramming can generate fibroblasts into hepatogenic cells. We directly induced human dermal fibroblasts (HDFs) into hepatocyte-like cells mediated by environmental transition-guided cellular reprogramming (h/entr) using ultrasound. We confirmed the characteristics of h/entr by the expression levels of hepatocyte specific RNA and proteins. The effects of h/entr on the activation of hepatic stellate cells were analyzed using conditioned medium (CM). h/entr were transplanted into mice with acute liver fibrosis and the therapeutic effects and mechanism of liver fibrosis were determined. h/entr exhibited high levels of hepatocyte specific genes, hepatogenic (hepatocyte growth factor [HGF], colony-stimulating factor 3 [CSF-3]) and anti-inflammatory (interleukin 10 [IL-10]) factors. h/entr CM suppressed the activation of hepatic stellate cells in vitro. Transplantation of h/entr significantly delayed liver fibrosis and improved liver function. Transplantation of h/entr accelerates liver regeneration, and human albumin expressing h/entr and human Alu gene were detected in the mouse livers. This report suggests that directly induced h/entr could be one of the highly effective therapeutic options for the treatment of liver cirrhotic disease.

Abstract
Ischemic stroke is one of the most common cerebrovascular diseases and is the leading cause of disability all over the world. It is well known that cerebral blood flow (CBF) is disturbed or even disrupted when ischemic stroke happens. The imbalance between demand and shortage of blood supply makes ischemic stroke take place or worsen. The search for treatments that can preserve CBF, especially during the acute phase of ischemic stroke, has become a research hotspot. Animal and clinical experiments have proven that remote ischemic conditioning (RIC) is a beneficial therapeutic strategy for the treatment of ischemic stroke. However, the mechanism by which RIC affects CBF has not been fully understood. This review aims to discuss several possible mechanisms of RIC on the cerebral hemodynamics in ischemic stroke, such as the improvement of cardiac function and collateral circulation of cerebral vessels, the protection of neurovascular units, the formation of gas molecules, the effect on the function of vascular endothelial cells and the nervous system. RIC has the potential to become a therapeutic treatment to improve CBF in ischemic stroke. Future studies are needed to highlight our understanding of RIC as well as accelerate its clinical translation.

Abstract
Although human adipose tissue-derived stromal vascular fraction (SVF) has been considered a promising source of stem cells, its characteristics relevant to treatment of a damaged liver have not been fully elucidated. In the present study, we sought to characterize the property of human SVF and determine the therapeutic utility of SVF in the liver cirrhosis model. We performed microarray, quantitative (q)-PCR experiments, and in vivo therapeutic assays using a liver cirrhotic mouse model. q-PCR results revealed that hepatocyte growth factor (HGF), vascular endothelial growth factor (VEGF)-A, Interleukin (IL)-10 and microRNA (miR)-146 were more highly upregulated in SVF than in human adipose-derived mesenchymal stem cells (ASCs). The SVF culture medium (CM) inhibited the activation of hepatic stellate cells in vitro. Injection of SVF significantly suppressed TAA-induced liver fibrosis and repaired liver function by inhibition of infiltrating inflammatory cells and induction of capillary/hepatocyte regeneration in vivo. Injection of IL-10 siRNA treated SVF cells decreased anti-inflammation and anti-fibrotic effects in TAA-induced mice liver. Our data indicate that SVF show a high anti-inflammatory property for treating fibrotic liver diseases through IL-10 secretion. Therefore, SVF might be a novel therapeutic alternative for the treatment of liver cirrhosis in clinical settings.
