Ulcerative colitis (UC) is one of the most important chronic inflammatory bowel diseases (IBD), and the aetiology of UC involves the interplay of genetic susceptibility, immune dysregulation, gut microbes and environmental factors. The cAMP response element modulator (CREM), a major effector of cAMP signalling, is a key transcription factor belonging to the cAMP response element binding protein (CREB) family. It integrates multiple upstream signaling pathways with distinct functions, such as cAMP/PKA, Ca2+/CaMKIV and AKT/mTOR. According to the urgent research, aberrant CREM expression occurs in colonic mucosal tissues and immune cells of UC patients which suggests its significant role in UC pathogenesis through multiple mechanisms. This review systemically summarizes the basic biological features of CREM, which comprises structural characteristics, isoform diversity, and regulatory networks in cellular signaling. In addition, we systematically analyse the main mechanisms by which CREM facilitates UC including the functions of immune cells, T cells, B cells and NK cells. Then we discuss the balance between pro-inflammatory and anti-inflammatory cytokines and the impact on intestinal barrier and gut microbiota. Ultimately, we will address the emerging resources, clinical potential of CREM as a healing target and pathway for future research. The purpose of this review is to provide novel insights into the pathogenesis of UC, which may contribute to optimizing clinical treatment and developing new therapeutic drugs.
BackgroundUlcerative colitis (UC) is an inflammatory bowel disease characterized by persistent colonic inflammation. Here, we performed a systematic analysis to gain better insights into UC pathogenesis.MethodsWe analyzed two UC-related datasets extracted from the gene expression omnibus database using several bioinformatics tools. The primary cell types and key subgroups of primary cells associated with UC and differentially expressed genes (DEGs) between UC and control samples were identified. The molecular regulation of the key genes was also predicted. The gene ontology and Kyoto encyclopedia of genes and genomes enrichment analyses of marker genes of key cell subgroups and model genes were performed. The expression of key enriched genes was validated in 10 clinical samples using real-time quantitative polymerase chain reaction (RT-qPCR).ResultsMonocytes were identified as the major cell type. Ten differentially expressed marker genes were obtained by intersecting the 3121 DEGs, 38 marker genes in major cell types, and 104 marker genes in key cell subgroups. Four essential genes, associated with immune response, were obtained using support vector machine recursive feature elimination and least absolute shrinkage and selection operator analyses. The four essential genes were highly expressed in Cluster 0 during differentiation. Validation of the four key genes in colonic mucosal biopsy specimens from 10 normal and 10 UC patients revealed that CREM was highly expressed in both the lesion-free sites and lesion sites colonic mucosa of UC patients compared with normal adults.ConclusionsWe identified CREM involved in UC pathogenesis, which is expected to provide a new therapeutic target for UC.
BACKGROUND:Chronic Kidney Disease (CKD) leads to structural and functional abnormalities of the kidneys and seriously jeopardizes human health. Shenyan Oral Liquid (SOLI), a Chinese medicinal preparation, has been reported to protect podocytes in patients with chronic kidney disease (CKD). OBJECTIVE:The objective of this study is to investigate the mechanism of action of the Chinese medicinal preparation Senyan Oral Liquid (SOLI) in the treatment of CKD by protecting podocytes through network pharmacology technology and experimental validation. METHODS:Compounds of SOLI and targets of CKD disease were collected and screened. The SOLI network of bioactive compounds targeting CKD and the protein-protein interaction (PPI) network were constructed using Cytoscape software and the STRING online database. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses were performed using the R software Cluster Profiler package. Molecular docking was performed using Autodock software to verify the binding ability of bioactive compounds and target genes. Subsequently, the potential mechanism of SOLI on CKD predicted by network pharmacological analysis was experimentally studied and verified in an adriamycin-induced nephropathy rat model. RESULTS:A total of 81 targets of SOLI components acting on CKD were identified. The results of the PPI analysis clarified that five key target genes (TNF, AKT1, IL6, VEGFA, and TP53) play a critical role in the treatment of CKD by SOLI. The GO analysis and KEGG enrichment analysis indicated that SOLI acts through multiple pathways, including the PI3K/AKT signaling pathway against CKD. Molecular docking showed that the main compounds of SOLI and five key genes had strong binding affinity. In a rat model of adriamycin-induced nephropathy, SOLI significantly ameliorated disease symptoms and improved renal histopathology. Mechanistic studies showed that SOLI upregulated the expression level of Nephrin, inhibited the PI3K/AKT pathway in renal tissues, and ultimately suppressed the activation of autophagy-related proteins in CKD. CONCLUSION:SOLI exerted a renoprotective effect by regulating the Nephrin-PI3K/AKT autophagy signaling pathway, and these findings provide new ideas for the development of SOLI-based therapeutic approaches for CKD.
Abstract Background Huangkui Lianchang Decoction (HLD) is a traditional Chinese herbal formula for treating ulcerative colitis (UC). However, its mechanism of action remains poorly understood. The Study aims to validate the therapeutic effect of HLD on UC and its mechanism by integrating network pharmacology, bioinformatics, and experimental validation. Methods UC targets were collected by databases and GSE19101. The active ingredients in HLD were detected by ultra-performance liquid chromatography-tandem mass spectrometry. PubChem collected targets of active ingredients. Protein–protein interaction (PPI) networks were established with UC-related targets. Gene Ontology and Kyoto Encyclopedia (KEGG) of Genes and Genomes enrichment were analyzed for the mechanism of HLD treatment of UC and validated by the signaling pathways of HLD. Effects of HLD on UC were verified using dextran sulfate sodium (DDS)-induced UC mice experiments. Results A total of 1883 UC-related targets were obtained from the GSE10191 dataset, 1589 from the database, and 1313 matching HLD-related targets, for a total of 94 key targets. Combined with PPI, GO, and KEGG network analyses, the signaling pathways were enriched to obtain IL-17, Toll-like receptor, NF-κB, and tumor necrosis factor signaling pathways. In animal experiments, HLD improved the inflammatory response of UC and reduced UC-induced pro-inflammatory factors such as Tumor Necrosis Factor Alpha (TNF-α), interleukin 1β (IL-1β), and interleukin 6 (IL-6). HLD suppressed proteins TLR4, MyD88, and NF-κB expression. Conclusions This study systematically dissected the molecular mechanism of HLD for the treatment of UC using a network pharmacology approach. Further animal verification experiments revealed that HLD inhibited inflammatory responses and improved intestinal barrier function through the TLR4/MyD88/NF-κB pathway.

Tumor angiogenesis, which may be affected by microenvironmental inflammation and promotes tumor development and metastasis, is one of the key reasons contributing to increased mortality. The goal of this study is to investigate how lignin analogs, specifically honokiol (HNK), block angiogenesis induced by the inflammatory milieu of lung cancer. The human lung cancer cell lines A549 and H460 were treated with HNK. Interleukin-1 was employed to mimic an inflammatory tumor microenvironment. Findings demonstrated that HNK drastically decreased the cell viability of A549 and H460 cells. In A549 and H460 cells, HNK also reduced the production of vascular endothelial growth factor (VEGF), the most important marker of tumor angiogenesis. Signal pathway studies revealed that HNK blocked the NF-KB signaling pathway. This effect, in turn, prevented the expression of VEGF by inhibiting the NF-KB signaling pathway. Human umbilical vein endothelial cells (HUVECs) from A549-conditioned medium cultures were subjected to HNK treatment, which decreased tubulogenesis, horizontal and vertical migration, and cell proliferation in HUVECs. Overall, HNK inhibited the NF-KB pathway. This effect resulted in the downregulation of VEGF, thus reducing the viability and angiogenesis of human lung cancer cell lines. In A549 cell xenografts, HNK decreased VEGF expression, tumor angiogenesis, and tumor development. Our research shows that HNK is a potential antiangiogenic molecule for the treatment of lung cancer.
Xiben Pills (XBP) are a Chinese medicine prescription with long history of use against lung cancer. Modern pharmacological experiments proved that XBP and its main compounds have anti-tumor effects. However, the mechanism by which XBP inhibits the progression of non-small cell lung cancer remains unclear.This study aimed to explore the potential targets and mechanism of XBP in the treatment of non-small cell lung cancer by network pharmacology and biological experiments.Network pharmacology was used to screen the prospective targets, pathways, and central genes of XBP in the treatment of non-small cell lung cancer. Based on the results of network pharmacology, the active ingredients of XBP were docked with the core target molecules of NSCLC. The viability of A549 and H460 cells was detected by CCK-8 method. Flow cytometry and Hoechst staining were used to detect cell apoptosis and Caspase 3 expressions in each group. Western blot verified the key protein expression underlying XBP’s therapeutic effect on NSCLC. A549 xenograft tumor model was used to evaluate the inhibitory effect of XBP on lung cancer. Apoptotic proteins Bax and Bcl-2 were detected in the tumor by immunohistochemistry.Ninety active ingredients and 191 potential drug targets were screened from XBP. A total of 280 pathways were enriched. Through these analyses, AKT1 was identified as a potential target for XBP to inhibit NSCLC. Molecular docking results showed that XBP ingredients had high affinity with AKT1. XBP significantly inhibited cell proliferation in A549 and H460 in a concentration-dependent manner. XBP induced the apoptosis of A549 cells and increased Caspase 3 expression. XBP significantly increased Bax and Caspase 3 expressions and inhibited Bcl-2 protein level. The mechanism of action was XBP’s inhibition of AKT phosphorylation. Xenograft results showed that XBP could inhibit lung cancer tumor growth and induce tumor cell apoptosis.Our research proved the anti-NSCLC effect of XBP through network pharmacology analysis and experiments. Results give a theoretical basis for XBP’s clinical anti-tumor effect and lay the foundation for further research on XBP.
