Furthermore, captopril enhanced the decreased SM22 expression in calcified arteries by fluorescence assay. Finally, the calcification arteries increased the p38, p-ERK and RANKL expression, which were downregulated by captopril treatment. CONCLUSIONS We concluded that captopril attenuated the increased connexin 43 expression and enhanced the MGP and SM22 expression levels, which are associated with the inactivation of p-ERK, p38 and RANKL pathways in rat aortic arteries. BACKGROUND Interleukin-19 (IL-19) has been shown to be involved in coronary artery diseases and atherosclerosis, while its expression in myocardial infarction is poorly understood. In this study, the dynamic increase in circulating IL-19 in acute ST-segment elevation myocardial infarction (STEMI) patients was detected. METHOD Both plasma IL-19 levels and IL-19 mRNA expression in peripheral blood mononuclear cells (PBMCs) from STEMI patients and chest pain syndrome (CPS) patients were detected at different time points, including 1 d, 3 d, 7 d and 14 d after treatment and on admission. RESULTS Compared with the CPS patients, IL-19 levels and IL-19 gene expression were significantly increased in STEMI patients and peaked at 1 d. From 1-14 d, refocusing treatment, including emergency percutaneous coronary intervention (PCI) and thrombolysis, markedly reduced IL-19 expression and promoted its recovery; of the treatments, the effect of emergency PCI was most significant. In addition, similar trends were also observed with cTnI, NT-proBNP and C-reactive protein (CRP) levels. Furthermore, correlation analysis showed that IL-19 levels were positively correlated with cTnI, NT-proBNP, CRP levels and left ventricular ejection fraction (LVEF) in STEMI patients. CONCLUSIONS IL-19 is correlated with the severity of acute myocardial infarction, which may be a new idea for the clinical treatment of myocardial infarction. BACKGROUND The role of Notch signaling dysregulation in causing metastatic breast cancer is not yet elucidated, therefore, this study aimed to investigate the expression of DLL4 and JAG1 in metastatic breast cancer. Moreover, we examined the possible association between clinicopathological features and studied parameters. DESIGN AND METHODS A total of 90 patients with invasive ductal breast carcinomas (52 non-metastatic and 38 metastatic) were enrolled in the current study. Furthermore, there were 42 patients with benign breast diseases. The mRNA and protein expression of DLL4 and JAG1 were analyzed by RT-PCR and ELISA, respectively in breast cell lysates. RESULTS The mRNA and protein expression of DLL4 and JAG1 were obviously higher in patients with breast cancer compared to patients with benign breast diseases and in metastatic versus non-metastatic breast cancer. A significant positive correlation was declared between DLL4 and JAG1 at both mRNA and protein levels in metastatic and localized breast cancer patients. Highly expressed mRNA and protein of DLL4 and JAG1 were associated with late tumor stages; moreover, upregulation of mRNA and protein of JAG1 was correlated with poorly differentiated tumors. CONCLUSION Our data emphasize that overexpression of DLL4 and JAG1 could predict the development of distant metastasis in breast cancer patients. BACKGROUND Several chronic diseases are mediated by oxidative stress. Oxidative stress affects cell morphology and function and is associated with alterations in the serum protein component. In the current study, we analyzed four individual prognostic factors associating with serum Pro-Oxidant-Antioxidant Balance (PAB) neutrophil to lymphocyte ratio (NLR), Vitamin D, anti-heat shock protein 27 (anti-hsp27) antibody titer, and red blood cell distribution width (RDW) to evaluate them as the potential prognostic markers. In the current study, we attempted to investigate the relationship between serum PAB, RDW, NLR, serum vitamin D and anti-hsp27 concentration. METHODS A total of 852 participants (438 males and 414 females) aged 47.64 ± 7.77 years were recruited in a cross-sectional study based on the Mashhad stroke and heart atherosclerotic disorders (MASHAD) cohort study data. Hematological parameters, and vitamin D, PAB and anti-hsp27 antibody titers were measured using the Sysmex auto analyzer system and enzyulation may help further confirm these findings. BACKGROUND AND AIMS Long noncoding RNAs have been proved to play a key role in the development and progression of various tumors, including osteosarcoma (OS). However, the role and molecular mechanism of lncRNA in osteosarcoma metastasis remains unknown. Our purpose is to explore the clinical significance and biological function of LINC01354 in osteosarcoma. METHODS Expression of LINC01354 in OS tissues, serum and cell lines was measured and the association between LINC01354 expression and clinicopathological factors was analyzed. The functional effects of LINC01354 were examined in vitro by using transwell assays, western blot, immunohistochemistry (IHC) and in vivo in a xenograft tumor mouse model. RESULTS LINC01354 was overexpressed in OS tissues, serum and cells. LINC01354 overexpression promoted OS cells invasion, EMT and integrin β1 expression, while knockdown of LINC01354 inhibited OS cell invasion, epithelial-mesenchymal transition (EMT) and integrin β1 expression. In addition, integrin-β1 blockage with MAB13 antibody abrogated the effects of LINC01354 overexpression on promoting OS cells invasion and EMT. In addition, LINC01354 promoted OS cell metastasis in vivo. CONCLUSION LINC01354 promote OS cell EMT and invasion through up-regulating integrin β1. Our study suggested that LINC01354 may be regarded as a potential target for the clinical treatment of OS. Zongertinib research buy BACKGROUND Inflammation plays an important role in promoting neurofibroma progression, and macrophages are key inflammatory cells in neurofibroma. AIM OF THIS STUDY We attempted to clarify the detailed mechanism of infiltrating macrophages promoting neurofibroma progression. METHODS We performed IHC and Western blot assays to detect the expression levels of OCT3/4, Nanog and SOX2 in tissues and cells. A colony/sphere formation assay was used to analyze cell stemness. MTT, colony formation assay and xenograft tumor model were used to detect cell growth. The transwell system was used to examine macrophage infiltration. RESULTS We demonstrated increased macrophage infiltration in neurofibroma tissues accompanied by increased stem cell-like markers. Moreover, Nf1-mutated SW10 cells possessed a stronger capacity to recruit macrophages, which in turn facilitated neurofibroma growth. Mechanistically, the infiltrating macrophages induced neurofibroma cell stem cell transition by modulating PI3K/AKT/GSK3β signaling, which then enhanced neurofibroma cell viability in vivo and in vitro.
