Abstract
Src-homology region 2 domain-containing phosphatase 1 (SHP-1) is considered an anti-inflammatory factor, but its role in chronic obstructive pulmonary disease (COPD) remains unknown. Herein, overexpression of SHP-1 was utilized to explore the functions of SHP-1 in COPD models established by stimulating 16HBE cells with cigarette smoke extracts (CSE) in vitro. SHP-1 was downregulated in both COPD patients and CES-treated 16HBE cells. SHP-1 overexpression reinforced cell viability and significantly prevented CSE-induced cell apoptosis in 16HBE cells. Furthermore, SHP-1 overexpression greatly reversed the CSE-induced migration, epithelial-mesenchymal transition (EMT), and pro-inflammatory factor production in 16HBE cells. In addition, CSE activated the P65 and PI3K/AKT pathways in 16HBE cells, which was also reversed by SHP-1 overexpression. Our findings indicated that SHP-1 alleviated CSE-induced EMT and inflammation in 16HBE cells, suggesting that SHP-1 regulated the development of COPD, and these functions may be linked to the inhibition of the PI3K/AKT pathway.

Abstract
Recurrent miscarriage (RM) has a huge impact on women. Both oxidative stress and ferroptosis play an important role in the pathogenesis of RM. Hence, it was vital to screen the ferroptosis oxidation-related biomarkers for the diagnosis and treatment of RM. We introduced transcript data to screen out differentially expressed genes (DEGs) in RM. Ferroptosis oxidation-related differentially expressed genes were obtained by overlapping DEGs and oxidative stress related genes with correlations >0.9 with ferroptosis-related genes. Least Absolute Shrinkage and Selectionator operator regression and support vector machine based recursive feature elimination algorithm were implemented to screen feature genes. The biomarkers associated with ferroptosis oxidation were screened via receiver operating characteristic curve analysis. We finally analyzed the competing endogenous RNAs regulatory network and potential drugs of biomarkers. We identified 1047 DEGs in RM. Then, 9 ferroptosis oxidation-related differentially expressed genes were obtained via venn diagram. Subsequently, 8 feature genes (PTPN6, GJA1, HMOX1, CPT1A, CREB3L1, SNCA, EPAS1, and TGM2) were identified via machine learning. Moreover, 4 biomarkers associated with ferroptosis oxidation, including PTPN6, GJA1, CPT1A, and CREB3L1, were screened via receiver operating characteristic curve analysis. We constructed the '227 long noncoding RNAs-4 mRNAs-36 microRNAs' network, in which hsa-miR-635 was associated with CREB3L1 and PTPN6. There were 11 drugs with therapeutic potential on 3 biomarkers associated with ferroptosis oxidation. We also observed higher expression of CPT1A and CREB3L1 in RM group compared to the healthy control group by quantitative real-time reverse transcription polymerase chain reaction. Overall, we obtained 4 biomarkers (PTPN6, GJA1, CPT1A, and CREB3L1) associated with ferroptosis and oxidative stress, which laid a theoretical foundation for the diagnosis and treatment of RM.

Abstract
PURPOSE To explore the association of the polymorphisms in PTPN6 and LncRNA C1RL-AS1 genes with ocular BD in Han Chinese patients. METHODS Correlation study was performed using the iPLEX system on a cohort of ocular BD patients andcontrols. The genotyping of 7 SNPs for LncRNA C1RL-AS1 and PTPN6 genes in ocular BD patients was performed using the iPLEX Gold genotype. RESULTS The frequencies of rs4013722 AG genotype/A allele in LncRNA C1RL-AS1 were significantly decreased in BD patients, and the frequency of GG genotype was significantly increased in BD patients. The rs4013722 was associated with ocular BD in male patients, but not in female patients. The AG and GG genotype of rs4013722 were associated with skin lesions in male patients.

Abstract
Introduction Ebola virus (EBOV) is an RNA virus of the Filoviridae family that is responsible for outbreaks of hemorrhagic fevers in primates with a lethality rate as high as 90%. EBOV primarily targets host macrophages leading to cell activation and systemic cytokine storm, and fatal infection is associated with an inhibited interferon response, and lymphopenia. The EBOV surface glycoprotein (GP) has been shown to directly induce T cell depletion and can be secreted outside the virion via extracellular vesicles (EVs), though most studies are limited to epithelial cells and underlying mechanisms remain poorly elucidated. Methods To assess the role of GP on EBOV-induced dysregulation of host immunity, we first utilized EBOV virus-like particles (VLPs) expressing VP40 and NP either alone (Bald-VLP) or in conjunction with GP (VLP-GP) to investigate early inflammatory responses in THP-1 macrophages and in a murine model. We then sought to decipher the role of non-classical inflammatory mediators such as EVs over the course of EBOV infection in two EBOV-infected rhesus macaques by isolating and characterizing circulatory EVs throughout disease progression using size exclusion chromatography, nanoparticle tracking-analysis, and LC-MS/MS. Results While all VLPs could induce inflammatory mediators and recruit small peritoneal macrophages, pro-inflammatory cytokine and chemokine gene expression was exacerbated by the presence of GP. Further, quantification of EVs isolated from infected rhesus macaques revealed that the concentration of vesicles peaked in circulation at the terminal stage, at which time EBOV GP could be detected in host-derived exosomes. Moreover, comparative proteomics conducted across EV populations isolated from serum at various time points before and after infection revealed differences in host-derived protein content that were most significantly pronounced at the endpoint of infection, including significant expression of mediators of TLR4 signaling. Discussion These results suggest a dynamic role for EVs in the modification of disease states in the context of EBOV. Overall, our work highlights the importance of viral factors, such as the GP, and host derived EVs in the inflammatory cascade and pathogenesis of EBOV, which can be collectively further exploited for novel antiviral development.

Abstract
Inflammatory pain is difficult to treat clinically, but electroacupuncture (EA) has been demonstrated to be effective in alleviating inflammatory pain. Programmed cell death ligand-1 (PD-L1) and its downstream signal, Src homology region two domain-containing phosphatase-1 (SHP-1) have a critical role in relieving inflammatory pain. However, whether the PD-L1/PD-1-SHP-1 pathway mediates the analgesic and anti-inflammatory effects of EA in inflammatory pain remains unclear. Here, we observed that EA reversed the complete Freund's adjuvant (CFA)-induced hyperalgesia. EA reduced the expression of IL-6, iNOS, and NF-κB pathway in dorsal root ganglia (DRG) on day 7 after CFA injection but had no effect on the expression of IL-6, iNOS, and NF-κB PP65 on day 21 after CFA injection. Moreover, EA upregulated the protein levels of the PD-L1/PD-1-SHP-1 pathway on day 7 and day 21 after CFA injection. Furthermore, EA upregulated PD-L1 expression in calcitonin gene-related peptide (CGRP)+ but not in isohaemagglutinin B4 (IB4)+ and NF200+ neurons on day 7 and day 21 after CFA injection. Intrathecal injection of the PD-L1/PD-1 inhibitor BMS-1 (50 or 100 µg) blocked the EA-induced analgesic effect, significantly increased IL-6 and iNOS levels, and reduced the levels of PD-L1/PD-1-SHP-1. BMS-1 (50 or 100 µg) significantly reduced the expression of PD-L1 in IB4+, CGRP+, and NF200+ neurons. Our results show that EA's anti-inflammatory and analgesic effects are associated with activating the PD-L1/PD-1-SHP-1 pathway and suppressing its regulated neuroinflammation. This study provides a new potential therapeutic target for treating inflammatory pain.

SHP2 inhibition enhances Yes-associated protein mediated liver regeneration in murine partial hepatectomy models. JCI Insight 2022; 7:159930. [PMID: 35763355 PMCID: PMC9462473 DOI: 10.1172/jci.insight.159930] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2022] [Accepted: 06/24/2022] [Indexed: 11/17/2022] Open
Abstract
Disrupted liver regeneration following hepatectomy represents an “undruggable” clinical challenge associated with poor patient outcomes. Yes-associated protein (YAP), a transcriptional coactivator that is repressed by the Hippo pathway, is instrumental in liver regeneration. We have previously described an alternative, Hippo-independent mechanism of YAP activation mediated by downregulation of protein tyrosine phosphatase nonreceptor type 11 (PTPN11, also known as SHP2) inhibition. Herein, we examined the effects of YAP activation with a selective SHP1/SHP2 inhibitor, NSC-87877, on liver regeneration in murine partial hepatectomy models. In our studies, NSC-87877 led to accelerated hepatocyte proliferation, improved liver regeneration, and decreased markers of injury following partial hepatectomy. The effects of NSC-87877 were lost in mice with hepatocyte-specific Yap/Taz deletion, and this demonstrated dependence on these molecules for the enhanced regenerative response. Furthermore, administration of NSC-87877 to murine models of nonalcoholic steatohepatitis was associated with improved survival and decreased markers of injury after hepatectomy. Evaluation of transcriptomic changes in the context of NSC-87877 administration revealed reduction in fibrotic signaling and augmentation of cell cycle signaling. Cytoprotective changes included downregulation of Nr4a1, an apoptosis inducer. Collectively, the data suggest that SHP2 inhibition induces a pro-proliferative and cytoprotective enhancement of liver regeneration dependent on YAP.

Abstract
This study investigates the expression of nonreceptor protein tyrosine phosphatase 6 (PTPN6) gene in different colon cancer cells and its effect on malignant biological behavior. The expression level of PTPN6 mRNA in different colon cancer cell lines was detected by qPCR. CCK-8, clone formation assay, scratch assay, and transwell assay were used to detect the effect of knockdown or overexpression of the PTPN6 gene on the malignant biological behavior of colon cancer cells. CO-IP assay was used to detect the interaction protein of PTPN6. PTPN6 was highly expressed in colorectal cancer tissues. High expression of PTPN6 is associated with poor prognosis in patients with colon cancer. PtPN6 knockdown inhibited the proliferation, invasion, migration, and clonogenesis of colorectal cancer LOVO and SW480 cells. At the same time, the knockdown of PTPN6 inhibited the EMT process in colorectal cancer. CO-IP results showed that PTPN6 had a protein-protein interaction with EGFR. Overexpression of EGFR increased the carcinogenic effect of PTPN6. The high expression of the PTPN6 gene can promote the proliferation, migration, and invasion of colon cancer cells. PTPN6 can interact with EGFR. PTPN6-EGFR complex may be an important factor affecting the biological characteristics of colon cancer cells and a potential therapeutic target.

Abstract
The abnormal expression of protein tyrosine phosphatase nonreceptor type 6 (PTPN6) has been proved to be associated with the progression of colorectal cancer. However, its role in chemosensitivity and related molecular mechanism have not been clarified. It has been reported that PTPN6 was down-regulated in colorectal cancer cells compared with the normal colorectal cells. To evaluate the effects of PTPN6 on the proliferation and survival of colorectal cancer cells, PTPN6 was overexpressed in colorectal cancer cells in the present study. We found that cell proliferation and viability were both decreased after overexpression of PTPN6. The IC50 of 5-Fu against colorectal cells was also declined in PTPN6 transfected cells. And further, we verified that PTPN6 could down-regulate the expression of P-gp and MRP-1. Moreover, SP1 was the target protein of PTPN6 predicated by ChIPBase software and confirmed through Co-immunoprecipitation assay and it was negatively regulated by PTPN6. To further verify the effect of SP1 on chemoresistance, SP1 was overexpressed. SP1 overexpression enhanced the drug-resistance to 5-Fu and abrogated the effects of PTPN6 upregulation on 5-Fu resistance. All the above changes were associated with the down-regulation of proteins related to MAPK signalling pathway, such as phosphorylation of extracellular regulated protein kinases (ERK) and p38. In summary, PTPN6 promoted chemosensitivity of colorectal cancer cells by targeting SP1 and inhibiting the activation of MAPK signalling pathway. SIGNIFICANCE OF THE STUDY: It has been demonstrated that the abnormal expression of PTPN6 was related to the progression of colorectal cancer. However, the chemosensitivity of PTPN6 and its molecular mechanisms were still unclear. Here, we identified that PTPN6 was down-regulated in colorectal cancer cells. Moreover, PTPN6 overexpression not only reduced cell proliferation and viability, but decreased the resistance of colorectal cells to 5-Fu. In our research, we found that the SP1 was the target protein of PTPN6 and it was negatively regulated by PTPN6. In addition, SP1 could increase the resistance of colorectal cells to 5-Fu. Molecular mechanism studies have shown that PTPN6 promoted the chemosensitivity of colorectal cancer cells by inhibiting the activation of MAPK signalling pathway.

One week after intravitreal injection of short hairpin RNA targeting SHP-1 or SHP-1 overexpression lentivirus in rats, we induced ocular inflammation with an intravitreal injection of lipopolysaccharide (LPS). We then assessed the extent of inflammation and performed full-field electroretinography. The concentrations and retinal expression of various inflammatory mediators were examined with enzyme-linked immunosorbent assays and Western blotting, respectively. SHP-1 overexpression and knockdown were induced in Müller cells to study the role of SHP-1 in the LPS-induced inflammatory response in vitro. Retinal SHP-1 expression was up-regulated by LPS. SHP-1 knockdown exacerbated LPS-induced retinal dysfunction and increased the levels of proinflammatory mediators in the retina, which was abrogated by a c-Jun N-terminal kinase (JNK) inhibitor (SP600125). SHP-1 overexpression had the opposite effects. In Müller cells, the LPS-induced inflammatory response was enhanced by SHP-1 knockdown and suppressed by SHP-1 overexpression. SHP-1 negatively regulated the activation of the transforming growth factor-β-activated kinase-1 (TAK1)/JNK pathway, but not the nuclear factor-κB pathway. These results indicate that SHP-1 represses EIU, at least in part, by inhibiting the TAK1/JNK pathway and suggest that SHP-1 is a potential therapeutic target for uveitis.

Abstract
Inflammation is the main contributor for the pathogenesis of nonalcoholic steatohepatitis (NASH). Src homology region 2 domain-containing phosphatase 1 (SHP-1, also known as PTPN6) is regarded as a negative regulator of inflammation, but its role in NASH remains unknown. Here, hepatocyte-specific Ptpn6 knockout mice (Ptpn6HKO ) and adenovirus vector-mediated ectopic expression of SHP-1 (AdSHP1) were used to evaluate the role of SHP-1 in a methionine- and choline-deficient diet-induced NASH model. Compared with the control littermates, Ptpn6HKO mice show exacerbated hepatic steatosis, inflammation, and fibrosis. Additionally, administration of AdSHP1 significantly ameliorates steatohepatitis and inhibits the expression of proinflammatory cytokines, including transforming growth factor-β, interleukin-6, and tumor necrosis factor-α. Our data indicate that SHP-1 could be a potential therapeutic target for NASH.

Abstract
Sepsis is a life-threatening condition caused by exaggerated host responses to infections taking place in two phases: (i) a systemic (hyper)inflammatory response syndrome (SIRS), participating in multiple organ failure (MOF), a major complication of septic shock, followed by (ii) a compensatory anti-inflammatory response syndrome (CARS), leading to sepsis-induced immunosuppression and resulting in late infections and long-term mortality. The Janus kinase-signal transducer and activator of transcription (JAK-STAT)-dependent signaling pathway is involved in both manifestations, hence playing a key role during sepsis. It is also involved in emergency myelopoiesis, which participates in host defense. The aim of this review is to highlight and refine the recent implications of this signaling pathway in sepsis and illustrate why its central position makes it a potential biomarker and therapeutic target.

Abstract
Background Cardiac dysfunction during endotoxemia is a major cause of cardiovascular disease with high morbidity and mortality. Alisol B 23-acetate (AB23A) is a triterpenoid extracted from the Rhizoma Alismatis, a kind of traditional Chinese medicine, exhibits anti-inflammatory activity on endotoxemia. This investigation aimed to uncover the protective effects of AB23A against sepsis-induced cardiac dysfunction. Material/Methods Adult male C57BL/6 mice received lipopolysaccharide (LPS) (20 mg/kg intravenous) stimulation, with or without pre-treatment of AB23A (10 mg/kg, 20 mg/kg, or 40 mg/kg). Histopathological staining and cardiac function were performed 4 hours after LPS stimulation. Then the levels of interleukin (IL)-6, IL-1β, and tumor necrosis factor (TNF)-α were monitored with enzyme-linked immunosorbent assay (ELISA). In addition, H9C2 cells were treated with LPS (5 μg/mL) with or without pre-treated with AB23A (0.1 μM, 1 μM, or 10 μM), and the production of reactive oxygen species (ROS) was detected by DCFH-DA combined with flow cytometry. The expression of Toll-like receptor 4 (TLR4), NADPH oxidase 2 (NOX2), NOX4, P38, p-P38, extracellular-signal-regulated kinase (ERK), and p-ERK were assessed by western blotting. Results AB23A improved the survival rate and ameliorated myocardial injury, decreased inflammatory infiltration and the level of IL-6, IL-1β, and TNF-α in the LPS-stimulated mouse model. Moreover, AB23A inhibited the ROS production in LPS-treated H9C2 cells. In addition, AB23A suppressed the levels of TLR4 and NOX2 as well as the activation levels of P38 and ERK both in vivo and in vitro. Conclusions AB23A reduced LPS-induced myocardial dysfunction by inhibiting inflammation and ROS production through the TLR4/NOX2 pathway.

FISH & SHELLFISH IMMUNOLOGY 2019; 88:244-253.

Abstract
Seasonal temperature has a major influence on the infectivity of pathogens and the host immune system. Viral hemorrhagic septicemia virus (VHSV) is one such pathogen that only causes the mortality of fish at low temperatures. This study aims to discover the host defense mechanism and pathway for resistance to VHSV at higher temperatures. We first observed the VHSV infection patterns at low and higher temperatures in fathead minnow (FHM) cells (20 °C and 28 °C) and zebrafish (15 °C and 25 °C). In comparison to the 20 °C infection, FHM cells infected at 28 °C showed decreased apoptosis, increased cell viability, and reduced VHSV N gene expression. In zebrafish, infection at 25 °C caused no mortality and significantly reduced the N gene copy number in comparison to infection at 15 °C. To explore the antiviral infection mechanisms induced by high temperature in vitro and in vivo, the changes in the proteomic profile were measured through UPLC-MSE analysis. ACADL, PTPN6, TLR1, F7, A2M, and GLI2 were selected as high temperature-specific biomarkers in the FHM cell proteome; and MYH9, HPX, ANTXR1, APOA1, HBZ, and MYH7 were selected in zebrafish. Increased immune response, anticoagulation effects, and the formation of lymphocytes from hematopoietic stem cells were analyzed as functions that were commonly induced by high temperature in vitro and in vivo. Among these biomarkers, GLI2 was predicted as an upstream regulator. When treated with GANT58, a GLI-specific inhibitor, cell viability was further reduced due to GLI2 inhibition during VHSV infection at varying temperatures in FHM cells, and the mortality in zebrafish was induced earlier at the low temperature. Overall, this study discovered a new mechanism for VHSV infection in vitro and in vivo that is regulated by GLI2 protein.
