In contrast, lower Glu in the aMCC correlated with BOLD contrasts in the posterior cingulate cortex (PCC). Furthermore, negative face detection was associated with prolonged response time (RT). Our results demonstrate a subregion-specific involvement of cingulate cortex Glu in interindividual differences during viewing of affective facial expressions. Glu levels in the pgACC were correlated with frontal area brain activations, whereas Glu in the salience network component aMCC modulated responses in the PCC-precuneus. We show that region-specific metabolite mapping enables specific activation of different BOLD signals in the brain underlying emotional perception. © 2020 Federation of European Neuroscience Societies and John Wiley & Sons Ltd.Tumor evasion from the host immune system is a substantial strategy for tumor development and survival. The expression of many immune checkpoint proteins in cancer cells is a mechanism by which tumor cells escape from the immune system. Among the well-known immune checkpoints that can tremendously affect tumor development and cancer therapy are the programmed death-ligand-1/programmed death-1 (PD-L1/PD-1). To tackle this phenomenon and improve the therapeutic strategies in cancer treatment, the blockade of the PD-L1/PD-1 pathway is introduced as a target, but the therapeutic advantage of PD L1/PD-1 blockade has not fulfilled the expectations. This condition may be associated with a different type of resistance in a considerable number of patients. A crucial issue to conquer resistance against immune checkpoint blockade therapy is to understand how PD-L1 level is regulated. However, the mechanisms by which the PD-L1 expression is regulated are complicated, and they can occur at different levels from signaling pathways to posttranscriptional levels. For example, various transcriptional factors, such as hypoxia-inducible factor-1, nuclear factor-κΒ, interferon-γ, STAT3, MYC, and AP-1 can regulate the PD-L1 distribution at the transcriptional level. Herein, we tried to focus on the most important regulatory mechanisms of PD-L1 by inducible agents in the tumor cells, such as signaling pathways, transcriptional factors, and posttranscriptional factors. Finally, these approaches may open up new windows for targeting tumor immune evasion and suggest the novel suppressors of PD-L1 for efficient therapeutics. © 2020 Wiley Periodicals, Inc.BACKGROUND AND OBJECTIVE The acute effects of e-cigarettes have not been scientifically demonstrated yet. The aim of this study was to assess the acute changes in pulmonary function and airway inflammation in patients with asthma after vaping one e-cigarette. METHODS Twenty-five smokers suffering from stable moderate asthma according to GINA guidelines with no other comorbidities and 25 healthy smokers matched with the baseline characteristics of the asthmatic patients were recruited. PFT, IOS, FeNO and EBC were performed before and after vaping one e-cigarette with nicotine. pH and concentrations of IL-1β, IL-4, IL-5, IL-6, IL-8, IL-10, IL-13, IL-17A, TNF-α, ISO8 and LTB4 were measured in EBC. RESULTS FFEV1/FVC ratio and PEF were reduced in asthmatic patients after e-cigarette. Z5Hz and R5Hz, R10Hz and R20Hz increased in both groups. FeNO and EBC pH increased by 3.60 ppb (P = 0.001) and 0.15 (P = 0.014) in asthmatic patients after e-cigarette, whereas they decreased in control group by 3.28 ppb (P  less then  0.001) and 0.12 (P = 0.064), respectively. The concentrations of IL-10, TNF-α and ISO8 in EBC increased in asthmatic patients after e-cigarette and the changes in concentrations of IL-1β and IL-4 differed significantly between the two groups. CONCLUSION E-cigarette vaping resulted in acute alteration of both pulmonary function and airway inflammation in stable moderate asthmatic patients. © 2020 Asian Pacific Society of Respirology.Plastin-3 plays a key role in cancer cell proliferation and invasion, but its prognostic value in pancreatic cancer (PACA) remains poorly defined. In this study, we show that PLS3 messenger RNA is overexpressed in PACA tissue compared with normal tissue. We accumulated 207 cases of PACA specimens to perform immunohistochemical analysis and demonstrated that PLS3 levels correlate with T-classification (p  less then  .001) and pathology (p  less then  .001). Furthermore, overall survival rates (p  less then  .001) in tumors with high PLS3 expression were poor, as assessed through Kaplan-Meier survival analysis. selleck compound PLS3 was found to be an independent prognostic factor for PACA through multivariate Cox regression analysis. Moreover, we found that PLS3 enhances the proliferation and invasion of tumor cells as assessed through Cell Counting Kit-8, wounding healing assays, and Transwell assays. The upregulation of PLS3 also led to enhanced phosphatidylinositol-3 kinase/protein kinase B signaling in PACA cells. These data suggest that PLS3 is a biomarker to estimate PACA progression and represents a molecular target for PACA therapy. © 2020 Wiley Periodicals, Inc.Current chemotherapy regimens on acute myeloid leukemia (AML) still have some drawbacks, such as intolerance and drug resistance, which calls need for the development of targeted therapy. Signal transducer and activator of transcription 5 (STAT5) is often overexpressed or abnormally activated in leukemia and involved in cell self-renewal, proliferation, and stress adaptation. Overexpressed Aurora A (AURKA) is associated with poor prognosis in tumors, and inhibitors against AURKA are already in clinical trials. However, it has rarely been reported whether AURKA inhibitors restrain STAT5-activated leukemia cells. In this study, we constructed STAT5 constitutively activated (cS5) cells and found that STAT5 promoted cell proliferation and colony formation. Moreover, cS5 cells showed elevated reactive oxygen species (ROS) and adenosine triphosphate (ATP) levels, which indicated higher mitochondrial metabolism in cS5 cells. A novel AURKA inhibitor AKI604 was synthesized and showed significant inhibitory effects to the proliferation and colony formation in both STAT5 constitutively activated and nonactivated AML cells. AKI604 induced mitochondrial impairment, leading to the disruption of mitochondrial membrane potential and the elevation of ROS as well as cellular calcium (Ca2+ ) levels. AKI604 could also decline basal oxygen consumption rate and ATP biosynthesis, indicating the damage of oxidative phosphorylation. Furthermore, AKI604 exhibited significant antitumor effect in the HL-60 cS5 xenograft model of the BALB/c nude mice without an obvious influence on mice body weight and other healthy indicators. This study suggested that AKI604 was a potential strategy to overcome STAT5-induced leukemic proliferation in AML treatment by inducing mitochondrial impairment. © 2020 Wiley Periodicals, Inc.
