Abstract
Acute type A aortic dissection is a life-threatening cardiovascular disease characterized by rapid onset and high mortality. Emergency surgery is the preferred and reliable treatment option. However, postoperative complications significantly impact patient prognosis. Hypoxemia, a common complication, poses challenges in clinical treatment, negatively affecting patient outcomes and increasing the risk of mortality. Therefore, it is crucial to study and comprehend the risk factors and treatment strategies for hypoxemia following acute type A aortic dissection to facilitate early intervention.

Overexpression of CD2/CD27 could inhibit the activation of nitrogen metabolism pathways and suppress M2 polarization of macrophages, thereby preventing brain metastasis of breast cancer. Transl Oncol 2023; 37:101768. [PMID: 37666207 PMCID: PMC10480780 DOI: 10.1016/j.tranon.2023.101768] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/04/2023] [Revised: 08/09/2023] [Accepted: 08/18/2023] [Indexed: 09/06/2023] Open
Abstract
OBJECTIVE Our study aimed to reveal the possible molecular mechanisms of CD2 and CD27 in influencing the tumor microenvironment of breast cancer (BC) brain metastasis based on the TCGA (The Cancer Genome Atlas) and SRA (Sequence Read Archive) databases. METHODS We calculated the proportions of tumor-infiltrating immune cells and the immune and stromal cell scores in 1222 BC samples from the TCGA-BRCA dataset, followed by identification of candidate DEGs. We further screened for BC brain metastasis-related DEGs in the BC brain metastasis dataset SUB12911144 from the SRA database. Finally, we established a mouse breast cancer brain metastasis model for in vivo validation. RESULTS We further screened two immune-regulatory DEGs (CD2 and CD27). GSEA analysis showed that the downregulation of CD2 and CD27 expression was closely related to the activation of nitrogen metabolism pathways. CIBERSORT algorithm analysis showed a correlation between the expression of 16 types of tumor-infiltrating immune cells and CD2 and 19 types of tumor-infiltrating immune cells and CD27. In addition, CD2 and CD27 expression were negatively associated with the proportion of M2 macrophages. In vivo experimental results demonstrated that overexpression of CD2/CD27 could suppress the M2 polarization of macrophages and inhibit breast cancer brain metastasis. CONCLUSION In the tumor microenvironment, overexpression of CD2/CD27 inhibited the activation of nitrogen metabolism pathways and suppressed M2 polarization of macrophages, thereby preventing brain metastasis of breast cancer.

Abstract
Tumor-associated macrophages (TAMs) possess great potential in the development of ovarian cancer (OC). Aberrant GATA-binding protein-3 (GATA3) expression has been found in TAM-derived extracellular vesicles (EVs). This study is intended to investigate the regulatory mechanism of TAM-derived EVs, expressing GATA3 in immune escape and chemotherapy resistance of OC cells. In silico analysis was employed to identify differentially expressed genes. The expression of GATA3, CD24, and sialic acid-binding igg-like lectin 10 (Siglec-10) in OC tissues and cells was characterized, with their correlation verified. OC cells were co-cultured with TAM-derived EVs and CD8+T cells. The functional significance of GATA3/CD24/Siglec-10 in immune escape and chemotherapy resistance of OC cells was assayed by the gain and loss of function experiments. In vivo experiments were also performed for further validation. High expressions of GATA3, CD24, and Siglec-10 were observed in OC tissues and cells. GATA3 could be transferred by TAM-derived EVs into OC cells, which facilitated immune escape and resistance to cisplatin of OC cells. GATA3 up-regulated CD24 to increase Siglec-10 expression. The in vivo assay confirmed the promoting effect of GATA3 delivered by TAM-derived EVs on OC through activation of the CD24/Siglec-10 axis. Collectively, TAM-derived EVs harboring GATA3 played a tumor-promoting role in immune escape and chemotherapy resistance of OC cells via the CD24/Siglec-10 axis.

[PMID: 35918714 PMCID: PMC9344728 DOI: 10.1186/s12967-022-03516-2] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2021] [Accepted: 06/30/2022] [Indexed: 11/16/2022] Open
Abstract
Background The resistance to radiotherapy remains a major obstacle that limits the efficacy of radiotherapy in non-small cell lung cancer (NSCLC). This study aims to illustrate the molecular mechanism underlying the role of LINC00665 in the radiosensitivity of NSCLC, which involves ubiquitin C-terminal hydrolase L3 (UCHL3). Methods and results The expression of UCHL3 was determined in clinical tissue samples collected from NSCLC patients and NSCLC cell lines. We found that UCHL3 overexpression occurred in both NSCLC tissues and cells, associated with poor prognosis in NSCLC patients. Mechanistically, UCHL3 stabilized aryl hydrocarbon receptor (AhR) protein through deubiquitination, thereby promoting PD-L1 expression. UCHL3 reduced the radiosensitivity of NSCLC cells by stabilizing AhR protein. Upstream microRNAs (miRNAs) and lncRNAs of UCHL3 were predicted by microarray profiling and validated by functional experiments. LINC00665 functioned as a sponge of miR-582-5p and thus up-regulated the expression of the miR-582-5p target UCHL3. Gain- and loss- of function assays were performed to assess the effects of LINC00665, UCHL3 and miR-582-5p on the in vitro cell malignant behaviors and immune escape as well as on the in vivo tumor growth. Silencing LINC00665 or overexpressing miR-582-5p enhanced the sensitivity of NSCLC cells to radiotherapy. LINC00665 augmented the immune escape of NSCLC cells in vitro and in vivo through stabilizing AhR protein via the miR-582-5p/UCHL3 axis. Conclusions Overall, LINC00665 reduced the radiosensitivity of NSCLC cells via stabilization of AhR through the miR-582-5p/UCHL3 axis.

Abstract
Worldwide, the prevalence of surgery under general anesthesia has significantly increased, both because of modern anesthetic and pain-control techniques and because of better diagnosis and the increased complexity of surgical techniques. Apart from developing new concepts in the surgical field, researchers and clinicians are now working on minimizing the impact of surgical trauma and offering minimal invasive procedures due to the recent discoveries in the field of cellular and molecular mechanisms that have revealed a systemic inflammatory and pro-oxidative impact not only in the perioperative period but also in the long term, contributing to more difficult recovery, increased morbidity and mortality, and a negative financial impact. Detailed molecular and cellular analysis has shown an overproduction of inflammatory and pro-oxidative species, responsible for augmenting the systemic inflammatory status and making postoperative recovery more difficult. Moreover, there are a series of changes in certain epigenetic structures, the most important being the microRNAs. This review describes the most important molecular and cellular mechanisms that impact the surgical patient undergoing general anesthesia, and it presents a series of antioxidant therapies that can reduce systemic inflammation.

Abstract
As a self-degradative mechanism, macroautophagy/autophagy has a role in the maintenance of energy homeostasis during critical periods in the development of cells. It also controls cellular damage through the eradication of damaged proteins and organelles. This process is accomplished by tens of ATG (autophagy-related) proteins. Recent studies have shown the involvement of non-coding RNAs in the regulation of autophagy. These transcripts mostly modulate the expression of ATG genes. Both long non-coding RNAs (lncRNAs) and microRNAs (miRNAs) have been shown to modulate the autophagy mechanism. Levels of several lncRNAs and miRNAs are altered in this process. In the present review, we discuss the role of lncRNAs and miRNAs in the regulation of autophagy in diverse contexts such as cancer, deep vein thrombosis, spinal cord injury, diabetes and its complications, acute myocardial infarction, osteoarthritis, pre-eclampsia and epilepsy.Abbreviations: AMI: acute myocardial infarction; ATG: autophagy-related; lncRNA: long non-coding RNA; miRNA: microRNA.

Abstract
Deep hypothermic circulatory arrest (DHCA) can cause acute lung injury (ALI), and its pathogenesis mimics ischaemia/reperfusion (I/R) injury. Autophagy is also involved in lung I/R injury. The present study aimed to elucidate whether DHCA induces natural autophagy activation and its role in DHCA‐mediated lung injury. Here, rats were randomly assigned to the Sham or DHCA group. The sham group (n = 5) only received anaesthesia and air intubation. DHCA group rats underwent cardiopulmonary bypass (CPB) followed by the DHCA procedure. The rats were then sacrificed at 3, 6 and 24 h after the DHCA procedure (n = 5) to measure lung injury and autophagy activity. Chloroquine (CQ) was delivered to evaluate autophagic flux. DHCA caused lung injury, which was prominent 3–6 h after DHCA, as confirmed by histological examination and inflammatory cytokine quantification. Lung injury subsided at 24 h. Autophagy was suppressed 3 h but was exaggerated at 6 h. At both time points, autophagic flux appeared uninterrupted. To further assess the role of autophagy in DHCA‐mediated lung injury, the autophagy inducer rapamycin and its inhibitor 3‐methyladenine (3‐MA) were applied, and lung injury was reassessed. When rapamycin was administered at an early time point, lung injury worsened, whereas administration of 3‐MA at a late time point ameliorated lung injury, indicating that autophagy contributed to lung injury after DHCA. Our study presents a time course of lung injury following DHCA. Autophagy showed adaptive yet protective suppression 3 h after DHCA, as induction of autophagy caused worsening of lung tissue. In contrast, autophagy was exaggerated 6 h after DHCA, and autophagy inhibition attenuated DHCA‐mediated lung injury.

Hypoxia-Inducible Factor Signaling in Inflammatory Lung Injury and Repair. Cells 2022; 11:cells11020183.

Abstract
Inflammatory lung injury is characterized by lung endothelial cell (LEC) death, alveolar epithelial cell (AEC) death, LEC-LEC junction weakening, and leukocyte infiltration, which together disrupt nutrient and oxygen transport. Subsequently, lung vascular repair is characterized by LEC and AEC regeneration and LEC-LEC junction re-annealing, which restores nutrient and oxygen delivery to the injured tissue. Pulmonary hypoxia is a characteristic feature of several inflammatory lung conditions, including acute lung injury (ALI), acute respiratory distress syndrome (ARDS), and severe coronavirus disease 2019 (COVID-19). The vascular response to hypoxia is controlled primarily by the hypoxia-inducible transcription factors (HIFs) 1 and 2. These transcription factors control the expression of a wide variety of target genes, which in turn mediate key pathophysiological processes including cell survival, differentiation, migration, and proliferation. HIF signaling in pulmonary cell types such as LECs and AECs, as well as infiltrating leukocytes, tightly regulates inflammatory lung injury and repair, in a manner that is dependent upon HIF isoform, cell type, and injury stimulus. The aim of this review is to describe the HIF-dependent regulation of inflammatory lung injury and vascular repair. The review will also discuss potential areas for future study and highlight putative targets for inflammatory lung conditions such as ALI/ARDS and severe COVID-19. In the development of HIF-targeted therapies to reduce inflammatory lung injury and/or enhance pulmonary vascular repair, it will be vital to consider HIF isoform- and cell-specificity, off-target side-effects, and the timing and delivery strategy of the therapeutic intervention.

Abstract
Long noncoding RNAs (lncRNAs) are abnormally expressed in numerous diseases, and they are closely associated with cardiac diseases. However, the role of lncRNAs in lipopolysaccharide (LPS)-induced cardiotoxicity as well as the potential mechanism remain largely unclear. In the present study, IncRNA microarray assays were performed to analyze differential lncRNA expression in LPS-treated cardiomyocytes, and lncRNA FGD5-AS1 was one of the downregulated lncRNAs. H9C2 cells were treated with LPS, and the expression of lncRNA FGD5-AS1 was markedly downregulated. LncRNA FGD5 overexpression decreased the LPS-induced cardiomyocyte apoptosis and inflammation. Bioinformatics analysis and a luciferase reporter assay indicated that lncRNA FGD5-AS1 directly binds to miR-223-3p. A miR-222-3p mimic partially reversed the inhibitory effect of lncRNA FGD5-AS1 on the LPS-induced H9C2 cell apoptosis and inflammatory response. Moreover, miR-223-3p directly targeted growth arrest-specific transcript 5 (GAS5). LncRNA FGD5-AS1 regulated LPS-induced H9C2 cell inflammation and apoptosis via the miR-223-3p/GAS5 axis.

Abstract
Background Excessive autophagic activity in alveolar epithelial cells is one of the main causes of acute lung injury (ALI), but the underlying molecular mechanism has not been fully elucidated. Previous studies have shown that microRNAs (miRs) are involved in regulating autophagy in several diseases. This study aimed to determine the role of miR-223 in excessive autophagic activity in alveolar epithelial cells and the underlying mechanism to identify a novel therapeutic targets for the development of new drugs to treat acute respiratory distress syndrome (ARDS). Methods A549 cells were treated with lipopolysaccharide (LPS) to establish an ALI in vitro model. The expression of miR-223 and its role of miR-223 in regulating oxidative stress and autophagy in the LPS-treated A549 cells, were examined using RT-PCR, flow cytometry and ELISA. A luciferase reporter assay was performed to verify the interaction between miR-223 and the high-mobility group box 2 (HMGB2) protein. Results The results showed that the LPS treatment downregulated miR-223 expression in alveolar epithelial cells. We further proved that miR-223 directly targeted the 3-untranslated region of the HMGB2 gene and the downregulation of miR-223 increased HMGB2 protein level, which activated the JNK signalling pathway and thus induced oxidative stress and autophagy in LPS-treated alveolar epithelial cells. Knockdown of HMGB2 protein deactivated the JNK signalling pathway and inhibited autophagy and oxidative stress in alveolar epithelial cells. Conclusions The results of this study suggest that miR-223 regulates oxidative stress and autophagy in alveolar epithelial cells by targeting HMGB2 via the JNK signalling pathway.

Int J Clin Pract 2021; 75:e14848. [PMID: 34519137 DOI: 10.1111/ijcp.14848] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/29/2021] [Accepted: 09/10/2021] [Indexed: 12/16/2022] Open
Abstract
AIM In this study, it was aimed to investigate the relationship between expression levels of micro-RNAs, endoplasmic reticulum (ER) stress, apoptosis and oxidative stress markers in hepatic ischaemia-reperfusion (IR) injury. METHODS Sixteen rats were randomised into two groups: Sham and IR groups. In the IR group, portal vein and hepatic artery were totally clamped with an atraumatic microvascular clamp and 60 minutes later unclamped and finally IR model was accomplished (60 minutes ischaemia and 60 minutes reperfusion). After sacrification, serum insulin-like growth factor-1 (IGF-1), tumour necrosis factor-α (TNF-α), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were measured. Liver tissue samples were evaluated histopathologically. The expression levels of IR1-alpha, Perk, Catalase, Gpx-1, Caspase-3, Bcl-2 genes and miR-33a, miR-221, miR-190b, miR-363-3p, miR-200c, miR-223, miR-133b were measured by quantitative real-time polymerase chain reaction method. RESULTS Biochemical parameters of the IR group showed significantly higher changes compared with the Sham group (P < .01). Histological tissue damage was significantly prominent in the IR group. ER stress, oxidative stress and apoptosis gene expression levels were significantly higher in the IR group (P < .01). Expression levels of miR-221, miR-190b, miR-363-3p and miR-200c were increased in the IR group compared with the Sham group. No significant difference was found between the two groups in terms of miR-33a, miR-133b and miR-223 expression levels (P > .05). CONCLUSION There is a strong need to enlighten the physiopathological and molecular mechanisms of liver IR injury and to find more specific biomarkers for IR damage, and miR-221, miR-190b, miR-363-3p and miR-200c maybe used as potential biomarkers of hepatic IR injury.

MicroRNAs Targeting HIF-2α, VEGFR1 and/or VEGFR2 as Potential Predictive Biomarkers for VEGFR Tyrosine Kinase and HIF-2α Inhibitors in Metastatic Clear-Cell Renal Cell Carcinoma. Cancers (Basel) 2021; 13:cancers13123099. [PMID: 34205829 PMCID: PMC8235409 DOI: 10.3390/cancers13123099] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2021] [Revised: 06/15/2021] [Accepted: 06/17/2021] [Indexed: 12/13/2022] Open
Abstract
Metastatic clear-cell renal cell carcinoma (m-ccRCC) is characterized by increased hypoxia-induced factor (HIF)-2α and vascular endothelial growth factor receptor (VEGFR)-dependent angiogenesis through loss of function of the von Hippel-Lindau protein. VEGFR tyrosine kinase inhibitors (VEGFR-TKIs) are a cornerstone of m-ccRCC treatment, and new treatments targeting HIF-2α are currently under investigation. However, predictive biomarkers for these treatments are lacking. In this retrospective cohort study including 109 patients treated with VEGFR-targeted therapies as first-line treatment, we aimed to study the possible predictive function of microRNAs (miRNAs) targeting HIF-2α, VEGFR1 and VEGFR2. We selected miRNAs inversely correlated with HIF-2α, VEGFR1 and/or VEGFR2 expression and with predicted target sites in the respective genes and subsequently studied their impact on therapeutic outcomes. We identified four miRNAs (miR-34c-5p, miR-221-3p, miR-222-3p and miR-3529-3p) inversely correlated with VEGFR1 and/or VEGFR2 expression and associated with tumor shrinkage and progression-free survival (PFS) upon treatment with VEGFR-TKIs, highlighting the potential predictive value of these miRNAs. Moreover, we identified three miRNAs (miR-185-5p, miR-223-3p and miR-3529-3p) inversely correlated with HIF-2α expression and associated with tumor shrinkage and PFS upon treatment with VEGFR-TKIs. These three miRNAs can have a predictive value not only upon treatment with VEGFR-TKIs but possibly also upon treatment with the upcoming HIF-2α inhibitor belzutifan.

Abstract
Recently study has indicated that hsa_circ_0007841 is up-regulated in patients with multiple myeloma and may act as an important biomarker in Multiple myeloma. However, the mechanisms and effects of hsa_circ_0007841 remain unclear and were firstly investigated herein. The gene expression
level was detected via PCR assay. The CCK-8 assay was performed to measure the cell viability. The cell proliferation capacity was evaluated via colony formation assay. The protein express level was detected by western blot and cell apoptosis via flow cytometry. The target of hsa_circ_0007841
was predicted via CircInteractome online tool and validated by luciferase reporter assay. Hsa_circ_0007841 was overexpressed and miR-507 was poorly expressed in multiple myeloma cells. Silencing hsa_circ_0007841 has anti-proliferation and pro-apoptosis effects in multiple myeloma cells. MiR-507
was found to be the target of hsa_circ_0007841. Inhibition of miR-507 relieved the effects of silencing hsa_circ_0007841 in myeloma cells. Silencing hsa_circ_0007841 suppressed cellular proliferative ability and enhanced cell apoptosis rate via targeting and up-regulating miRNA-507 in multiple
myeloma cells.
