Abstract
Systemic sclerosis (SSc) is a devastating autoimmune illness with a wide range of clinical symptoms, including vascular abnormalities, inflammation, and persistent and progressive fibrosis. The disease's complicated pathophysiology makes it difficult to develop effective therapies, necessitating research into novel therapeutic options. Molecular hybridization is a strategy that can be used to develop new drugs that act on two or multiple targets and represents an interesting option to be explored for the treatment of complex diseases. We aimed to evaluate the effects of a hybrid mutual prodrug of ibuprofen and acetaminophen (IBPA) in peripheral blood mononuclear cells (PBMC) isolated from SSc patients, and in an in vivo model of SSc induced in BALB/c mice by intradermal injections of hypochlorous acid (HOCl) for 6 weeks. The mice were treated at the same time with daily intraperitoneal injections of IBPA (40 mg/kg). Pulmonary and skin fibrosis as well as immune responses were evaluated. IBPA significantly decreased the release of cytokines in PBMC culture supernatants from SSc patients after stimulation with phytohemagglutinin-M (IL-2, IL-4, IL-6, IL-10, IL-13, IL-17A, TNF and IFN-γ).In HOCl-induced SSc, IBPA treatment prevented dermal and pulmonary fibrosis, in addition to reducing CD4 + T and B cells activation and reversing the M2 polarization of macrophages in spleen cells, and inhibiting IFN-γ secretion in splenocyte cultures. These results show the anti-inflammatory and antifibrotic effects of IBPA in SSc and highlight the therapeutic potential of this mutual prodrug, providing support for future studies.

Abstract
OBJECTIVES Systemic sclerosis (SSc) is an autoimmune disease caused by various pathogenic factors, including hypoxia. Hypoxia stimulates the production of the extracellular matrix to promote fibrosis. However, the integrated function and the underlying mechanism of hypoxia in SSc are unclear. METHODS In the present study, we used Agilent SurePrint G3 Human Gene Expression v3 for the transcriptional sequencing of fibroblasts with and without hypoxia to detect differentially expressed genes (DEGs) in hypoxia. We analyzed the results with the transcriptome data of SSc lesions (GSE95065) to select the co-DEGs. Then, Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses were performed on the basis of the co-DEGs using the R package ClusterProfiler, which showed that hypoxia and cross talk of hypoxia with other pathogenic factors are involved in the pathogenesis of SSc. Furthermore, we constructed a protein-protein interaction (PPI) network of co-DEGs and screened two significant functional expression modules. RESULTS We identified nine hub genes (ALDH1A1, EGF, NOX4, LYN, DNTT, PTGS2, TKT, ACAA2, and ALDH3A1). These genes affect the pentose phosphate pathway, oxidative stress, and lipolysis. CONCLUSION Our study provides insights into the mechanisms underlying the effects of hypoxia on SSc pathogenesis, which will help to better understand SSc pathogenesis and develop new therapeutic strategies for SSc.

Xu Z, Chen C. The Downregulation of PTGS2 Mediated by ncRNAs is Tightly Correlated with Systemic Sclerosis-Interstitial Lung Disease. Front Genet 2022; 12:795034. [PMID: 35096012 PMCID: PMC8793859 DOI: 10.3389/fgene.2021.795034] [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: 10/14/2021] [Accepted: 12/21/2021] [Indexed: 11/29/2022] Open
Abstract
Background: Interstitial lung disease in systemic sclerosis (SSc-ILD) is one of the most severe complications of systemic sclerosis (SSc) and is the main cause of mortality. In this study, we aimed to explore the key genes in SSc-ILD and analyze the relationship between key genes and immune cell infiltration as well as the key genes relevant to the hallmarks of cancer. Methods: Weighted gene co-expression network analysis (WGCNA) algorithm was implemented to explore hub genes in SSc-ILD samples from the Gene Expression Omnibus (GEO) database. Logistic regression analysis was performed to screen and verify the key gene related to SSc-ILD. CIBERSORT algorithms were utilized to analyze immune cell infiltration. Moreover, the correlation between the key genes and genes relevant to cancer was also evaluated. Furthermore, non-coding RNAs (ncRNAs) linking to PTGS2 were also explored. Results: In this study, we first performed WGCNA analysis for three GEO databases to find the potential hub genes in SSc-ILD. Subsequently, we determined PTGS2 was the key gene in SSC-ILD. Furthermore, in CIBERSORT analyses, PTGS2 were tightly correlated with immune cells such as regulatory T cells (Tregs) and was negatively correlated with CD20 expression. Moreover, PTGS2 was associated with tumor growth. Then, MALAT1, NEAT1, NORAD, XIST identified might be the most potential upstream lncRNAs, and LIMS1 and RANBP2 might be the two most potential upstream circRNAs. Conclusion: Collectively, our findings elucidated that ncRNAs-mediated downregulation of PTGS2, as a key gene in SSc-ILD, was positively related to the occurrence of SSc-ILD and abnormal immunocyte infiltration. It could be a promising factor for SSc-ILD progression to malignancy.

Objective clinical pain analysis using serum cyclooxygenase-2 and inducible nitric oxide synthase in American patients. Clin Chim Acta 2018; 484:278-283. [PMID: 29885320 DOI: 10.1016/j.cca.2018.06.005] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/04/2018] [Revised: 04/20/2018] [Accepted: 06/02/2018] [Indexed: 02/01/2023]
Abstract
BACKGROUND Pain is a multidimensional condition of multiple origins. Determining both intensity and underlying cause are critical for effective management. Utilization of painkillers does not follow any guidelines relying on biomarkers, which effectively eliminates objective treatment. The aim of this study was to evaluate the use of serum cyclooxygenase-2 (COX-2) and inducible nitric oxide synthase (iNOS) as pain biomarkers. This work could significantly advance the diagnosis and treatment of pain. METHODS We assessed the potential utility of serum COX-2 and iNOS as objective measures of pain in a sample of American patients. Pain was scaled between level 0-5 in accordance with the level reported by the patients. Blood samples were collected from 102 patients in the emergency room. Sandwich ELISA was used to determine the COX-2 and iNOS levels in the blood serum while statistical analysis was performed using Pearson product-moment correlation coefficients, Regression and Receiver Operating Characteristics (ROC) analyses. The biomarker results were also compared with self-reports of pain by the patients using conventional pain ratings and patients were asked to report the cause of the pain. Pain levels were clustered into four groups as 0 [self-reported 0], 1 [self-reported as 1], 2 [self-reported as 2 and 3] and 3 [self-reported as 4 and 5]. Co-expression of COX-2 and iNOS could significantly alter pain development and its sensitization. Therefore, iNOS dependent COX-2 levels were employed as categorized level. RESULTS Self-reported pain levels did not show a correlation with the serum level of COX-2 and iNOS. The lack of correlation is attributed to multiple reasons including patients' intake of painkillers prior to participation, painkiller intake habit, chronic diseases, and subjectivity of self-reported pain. Increased serum COX-2 levels were reported in relation to the subtypes of these health issues. Further, 83% of the patients who reported pain also showed the presence of COX-2 in serum, while only 53% of the patients showed the presence of iNOS in serum. Moderate relation was found between the clustered pain level and categorized COX-2 and iNOS- levels. CONCLUSIONS The findings support the requirement of further studies to use COX-2 and iNOS as prognostic biomarkers for objective quantification of pain at the clinical level.

Abstract
BACKGROUND The photothermal properties of gold nanoparticles (GNPs) are promising therapeutic modality for cancer. The study objective is to evaluate the therapeutic effect of the prepared PEGylated gold nano-semicubes (PEG-GNSCs) in skin cancer. The synthesized PEG-GNSCs were intermediate between cubic and rod shapes (low aspect ratio- rods). METHODS In vitro toxicity was investigated in human skin melanoma Sk-Mel-28 cells, and skin squamous cell carcinoma was induced in CD1 mice by dimethylbenzanthracene (DMBA) and 12-O-tetradecanoyl-phorbol-13-acetate (TPA). RESULTS The calculated IC50 in Sk-Mel-28 cells was 3.41μg/ml of PEG-GNSCs, in presence of laser exposure. Photothermal therapy using laser-stimulated PEG-GNSCs resulted in inhibited volume of skin tumors. Our findings indicated that the inflammatory mediators, nitric oxide and cycloxygenase-2, were inhibited in mice after being treated with low and high doses of PEG-GNSCs, accompanied with laser exposure. However, the tumor necrosis factor -α was markedly elevated, while there was no change in 5-lipoxygenase. The pro-angiogenic factor vascular endothelial growth factor was inhibited, while histone acetylation and apoptosis were induced in tumor-bearing groups, after being treated with laser-stimulated PEG-GNSCs. CONCLUSION The present study indicated the promising photothermal therapeutic effect of laser-stimulated PEG-GNSCs as an effective modality to inhibit the tumor growth, the angiogenesis and partially the inflammation.

Abstract
BACKGROUND Cyclooxygenase-2 (Cox-2) is frequently overexpressed in cervical carcinoma, but little is known about its altered serum concentration. Hence, this study evaluates clinical utility of cellular and serum level of Cox-2 enzyme in cervical cancer. METHODS The expression of Cox-2 was evaluated in cervical tissues and serum samples collected from normal controls (n = 100; n = 68), cervical intraepithelial neoplasia patients (CIN, n = 67; n = 12), and invasive squamous cell carcinoma patients (SCCs; n = 153; n = 127) by immunohistochemical and enzyme-linked immunosorbent assay (ELISA) analyses. RESULTS The significant cytoplasmic overexpression of Cox-2 was noted in 50.7% of CIN and 69.9% of SCCs as compared with normal (P = 0.0001). Serum level of Cox-2 was also found to be elevated both in CIN (median 4.35 ng/ml) and in SCCs (median 19.39 ng/ml) with respect to normal (median 0.44 ng/ml; P = 0.0001), respectively. The ROC analysis revealed the potential of serum Cox-2 over its cellular expression to distinguish CIN and SCCs from normal. CONCLUSION Augmented Cox-2 activity is implicated in the pathogenesis of cervical cancer, and its serum level could serve a potential to distinguish this malignancy. Therefore, it is suggested that serum Cox-2 may be useful in monitoring the diagnosis and treatment outcome of patients.

Abstract
OBJECTIVE: To study the expression of COX-1 and COX-2 in the remodeled lung in systemic
sclerosis (SSc) and idiopathic pulmonary fibrosis (IPF) patients,
correlating that expression with patient survival. METHODS: We examined open lung biopsy specimens from 24 SSc patients and 30 IPF
patients, using normal lung tissue as a control. The histological patterns
included fibrotic nonspecific interstitial pneumonia (NSIP) in SSc patients
and usual interstitial pneumonia (UIP) in IPF patients. We used
immunohistochemistry and histomorphometry to evaluate the expression of
COX-1 and COX-2 in alveolar septa, vessels, and bronchioles. We then
correlated that expression with pulmonary function test results and
evaluated its impact on patient survival. RESULTS: The expression of COX-1 and COX-2 in alveolar septa was significantly higher
in IPF-UIP and SSc-NSIP lung tissue than in the control tissue. No
difference was found between IPF-UIP and SSc-NSIP tissue regarding COX-1 and
COX-2 expression. Multivariate analysis based on the Cox regression model
showed that the factors associated with a low risk of death were younger
age, high DLCO/alveolar volume, IPF, and high COX-1 expression in alveolar
septa, whereas those associated with a high risk of death were advanced age,
low DLCO/alveolar volume, SSc (with NSIP), and low COX-1 expression in
alveolar septa. CONCLUSIONS: Our findings suggest that strategies aimed at preventing low COX-1 synthesis
will have a greater impact on SSc, whereas those aimed at preventing high
COX-2 synthesis will have a greater impact on IPF. However, prospective
randomized clinical trials are needed in order to confirm that.

Abstract
BACKGROUND Indocyanine green (ICG) is a promising water-soluble photosensitizer for photodynamic therapy (PDT) of tumors. It was reported to have promising phototoxic effect on different cell lines. This study aimed to evaluate the efficacy of ICG as an efficient PS agent for skin cancer induced in mice. METHODS Skin squamous cell carcinoma was induced in female CD-1 mice by 7,12-dimethylbenzanthracene and 12-O-tetradecanoyl-phorbol-13-acetate followed by an ICG/PDT treatment. The laser irradiation for PDT was adjusted to cover the whole body of the mice to make sure that the treatment protocol will be delivered to multiple tumors. RESULTS The treatment of skin cancer by ICG/PDT using intravenously injected ICG initiated tumor cell death and significantly decreased cell proliferation as indicated by the reduction in proliferating cell nuclear antigen positivity. A significant reduction in the inflammatory mediators; tumor necrosis factor-α, nitric oxide and 5-lipoxygenase was reported, however the level of cyclooxygenase-2 (COX-2) was significantly elevated after ICG/PDT treatment. CONCLUSION The proposed ICG/PDT treatment modality showed a significant anti-tumor and anti-inflammatory activity against skin cancer accompanied with COX-2 elevation.

Abstract
BACKGROUND Indocyanine green (ICG) is a promising photosensitive agent for photodynamic therapy (PDT) of tumors. Encapsulating ICG dye in polymeric nanoparticles based on PEBBLE technology forming (ICG-PEBBLE) could improve the aqueous stability of the entrapped ICG molecules. The study objective is to investigate the PDT effect of free ICG-PEBBLE and its Anti-EGFR conjugate. METHODS Skin squamous cell carcinoma was induced in CD1 mice by dimethylbenzanthracene (DMBA) and 12-O-tetradecanoyl-phorbol-13-acetate (TPA) followed by a PDT protocol for four weeks. RESULTS PDT using ICG-PEBBLE or ICG-PEBBLE-Anti-EGFR decreased skin tumor sizes. Our findings revealed that the inflammatory mediators tumor necrosis factor (TNF-α), nitric oxide (NO), cycloxygenase-2 (COX-2) and 5-lipoxygenase (5-LOX), the angiogenic mediator vascular endothelial growth factor (VEGF), and proliferating cell nuclear antigen (PCNA) were decreased, while apoptosis, caspase-3 and histone acetylation were induced in tumor bearing groups after PDT using both of ICG-PEBBLE or ICG-PEBBLE-Anti-EGFR. CONCLUSION The present study indicated the effectiveness of PDT using ICG-PEBBLE or ICG-PEBBLE-Anti-EGFR as an inhibitor modality for tumor size, apoptosis, angiogenesis and tumor inflammation. The conjugating of ICG-PEBBLE to anti-EGFR was found to be more effective in inhibiting VEGF and in increasing caspase-3 compared to free ICG-PEBBLE, but there were no other preferential PDT efficacy.
