Our previous study found that Calcium-Sensing Receptor (CaSR) is involved in pulmonary vascular remodeling in hypoxic pulmonary hypertension (HPH). However, the relationship of Pulmonary Artery Smooth Muscle Cell (PASMC) phenotypic switching, proliferation, and autophagy in CaSR-related HPH remain unclear. The purpose of this study was to detect the role of a CaSR antagonist, NPS2143, on the vascular remodeling by autophagy modulation under hypoxia. Methods: Hypoxic rat PAH model were simulated in vivo. Meanwhile, mean Pulmonary Artery Pressure (mPAP) was measured while RVI, WT%, and WA% indices were calculated. Immunohistochemistry and Western blot were used to detect phenotypic switching and cell proliferation in pulmonary arteriole. Cell viability was determined in vitro by CCK8 and cell cycle. Cell proliferation, phenotypic switching, autophagy level and PI3K/Akt/mTOR pathways were investigated in human PASMCs through mRNA or Western blot methods. Results: Rats with hypoxic-induced PAH had an increased mPAP, RVI, WT% and WA%. Moreover, expression of CaSR was significantly increased, followed by activation of autophagy (increased LC3b and decreased p62), phenotypic switching of PASMCs (reduced calponin, SMA-a and increased OPN) and pulmonary vascular remodeling. However, NPS2143 weakened these hypoxic effects. The results using hypoxic-induced human PASMCs confirmed that NPS2143 suppressed autophagy and reversed phenotypic switching in vitro by inhibiting PI3K/Akt/mTOR pathways. Conclusions: Our study demonstrates that NPS2143 was conducive to inhibit the proliferation and reverse phenotypic switching of PASMCs by regulating autophagy levels in HPH and vascular remodeling.","PeriodicalId":91561,"journal":{"name":"Journal of stem cell research and transplantation","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78007908","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The lymph node status is an important basis for formulating clinical treatment strategies of NSCLC, therefore comprehensive and profound understanding of risk factors for lymph node metastasis is essential. There are many known factors for lymph node metastasis in NSCLC, such as pathological subtypes, tumor size, tumor location. Meanwhile, whether the mutation of the driver gene affects the lymph node metastasis is still lacking enough research. This article aims to elaborate the relationship between NSCLC driver gene mutation and lymph node metastasis, from NSCLC lymph node metastasis-related risk factors, driver genes and lymph node metastasis, metastatic lymph node mutation status analysis and detection these several aspects to summarize the latest research progress in NSCLC driver gene mutation and lymph node metastasis risk. It also fully explained the correlation between driver gene mutations and NSCLC tumor biological behaviors such as lymph node metastasis.","PeriodicalId":91561,"journal":{"name":"Journal of stem cell research and transplantation","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90145540","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Individual treatments using human autologous cord blood Mononuclear Cells (hucbMNC) containing stem cells have yielded promising results. However, stroke is an entity with heterogenic etiologies including arterial ischemic stroke, hemorrhagic stroke, hemorrhagic infarction, and sinus venous thrombosis in newborns, infants, children, and adults. Hence, any attempt to examine care, non-cellular or cell-based therapies has to merit the specific characteristics of this heterogeneity as far as age, symptoms, diagnostics, pathophysiology, histopathology, clinical course and prevalence are concerned. This review describes the various etiologies of stroke for the Neonatal/Perinatal and childhood subsets of the pediatric population as a basis for established non-cellular and novel cell-based therapeutic approaches using cord blood mononuclear cells in the preclinical and clinical setting. In addition, due to its fundamental importance for cell-based therapeutic strategies for stroke, an account of brain plasticity along with blood-brain barrier function and the distinctions between the developing brain and the adult brain is provided. It is concluded that on the present balance of evidence the pathophysiological characteristics associated with plasticity of the developing brain are closely linked to the pharmacological action of hucbMNC in such a way that cell-based treatment might be more efficacious in pediatric stroke than in adult stroke.","PeriodicalId":91561,"journal":{"name":"Journal of stem cell research and transplantation","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78902005","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
