Wang R, Shi Y, Lv Y, Xie C, Hu Y. The novel insights of epithelial-derived exosomes in various fibrotic diseases. Biomed Pharmacother 2024; 174:116591. [PMID: 38631144 DOI: 10.1016/j.biopha.2024.116591] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2024] [Revised: 04/07/2024] [Accepted: 04/10/2024] [Indexed: 04/19/2024] Open
Abstract
The characteristics of fibrosis include the abnormal accumulation of extracellular matrix proteins and abnormal tissue repair caused by injury, infection, and inflammation, leading to a significant increase in organ failure and mortality. Effective and precise treatments are urgently needed to halt and reverse the progression of fibrotic diseases. Exosomes are tiny vesicles derived from endosomes, spanning from 40 to 160 nanometers in diameter, which are expelled into the extracellular matrix environment by various cell types. They play a crucial role in facilitating cell-to-cell communication by transporting a variety of cargoes, including proteins, RNA, and DNA. Epithelial cells serve as the primary barrier against diverse external stimuli that precipitate fibrotic diseases. Numerous research suggests that exosomes from epithelial cells have a significant impact on several fibrotic diseases. An in-depth comprehension of the cellular and molecular mechanisms of epithelial cell-derived exosomes in fibrosis holds promise for advancing the exploration of novel diagnostic biomarkers and clinical drug targets. In this review, we expand upon the pathogenic mechanisms of epithelium-derived exosomes and highlight their role in the fibrotic process by inducing inflammation and activating fibroblasts. In addition, we are particularly interested in the bioactive molecules carried by epithelial-derived exosomes and their potential value in the diagnosis and treatment of fibrosis and delineate the clinical utility of exosomes as an emerging therapeutic modality, highlighting their potential application in addressing various medical conditions.

Abstract
The energy needs of tubular epithelial components, especially proximal tubular epithelial cells (PTECs), are high and they heavily depend on aerobic metabolism. As a result, they are particularly vulnerable to various injuries caused by factors such as ischemia, proteinuria, toxins, and elevated glucose levels. Initial metabolic and phenotypic changes in PTECs after injury are likely an attempt at survival and repair. Nevertheless, in cases of recurrent or prolonged injury, PTECs have the potential to undergo a transition to a secretory state, leading to the generation and discharge of diverse bioactive substances, including transforming growth factor-β, Wnt ligands, hepatocyte growth factor, interleukin (IL)-1β, lactic acid, exosomes, and extracellular vesicles. By promoting fibroblast activation, macrophage recruitment, and endothelial cell loss, these bioactive compounds stimulate communication between epithelial cells and other interstitial cells, ultimately worsening renal damage. This review provides a summary of the latest findings on bioactive compounds that facilitate the communication between these cellular categories, ultimately leading to the advancement of tubulointerstitial fibrosis (TIF).

[PMID: 36889445 DOI: 10.1016/j.bcp.2023.115488] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2022] [Revised: 02/28/2023] [Accepted: 03/01/2023] [Indexed: 03/08/2023]
Abstract
The 90 kDa ribosomal S6 kinase (RSK) family of proteins is a group of highly conserved Ser/Thr kinases. They are downstream effectors of the Ras/ERK/MAPK signaling cascade. ERK1/2 activation directly results in the phosphorylation of RSKs, which further, through interaction with a variety of different downstream substrates, activate various signaling events. In this context, they have been shown to mediate diverse cellular processes like cell survival, growth, proliferation, EMT, invasion, and metastasis. Interestingly, increased expression of RSKs has also been demonstrated in various cancers, such as breast, prostate, and lung cancer. This review aims to present the most recent advances in the field of RSK signaling that have occurred, such as biological insights, function, and mechanisms associated with carcinogenesis. We additionally present and discuss the recent advances but also the limitations in the development of pharmacological inhibitors of RSKs, in the context of the use of these kinases as putative, more efficient targets for novel anticancer therapeutic approaches.

Abstract
BACKGROUND The role of the IL6 family members in organ fibrosis, including renal interstitial fibrosis (TIF), has been widely explored. However, few studies have ever simultaneously examined them in the same cohort of patients. Besides, the role of leukemia inhibitory factor (LIF) in TIF remains unclear. METHODS RNA-seq data of kidney biopsies from chronic kidney disease (CKD) patients, in both public databases and our assays, were used to analyze transcript levels of IL6 family members. Two TIF mouse models, the unilateral ureteral obstruction (UUO) and the ischemia reperfusion injury (IRI), were employed to validate the finding. To assess the role of LIF in vivo, short hairpin RNA, lenti-GFP-LIF was used to knockdown LIF receptor (LIFR), overexpress LIF, respectively. LIF-neutralizing antibody was used in therapeutic studies. Whether urinary LIF could be used as a promising predictor for CKD progression was investigated in a prospective observation patient cohort. FINDINGS Among IL6 family members, LIF is the most upregulated one in both human and mouse renal fibrotic lesions. The mRNA level of LIF negatively correlated with eGFR with the strongest correlation and the smallest P value. Baseline urinary concentrations of LIF in CKD patients predict the risk of CKD progression to end-stage kidney disease by Kaplan-Meier analysis. In mouse TIF models, knockdown of LIFR alleviated TIF; conversely, overexpressing LIF exacerbated TIF. Most encouragingly, visible efficacy against TIF was observed by administering LIF-neutralizing antibodies to mice. Mechanistically, LIF-LIFR-EGR1 axis and Sonic Hedgehog signaling formed a vicious cycle between fibroblasts and proximal tubular cells to augment LIF expression and promote the pro-fibrotic response via ERK and STAT3 activation. INTERPRETATION This study discovered that LIF is a noninvasive biomarker for the progression of CKD and a potential therapeutic target of TIF.

Disturbed flow-induced FAK K152 SUMOylation initiates the formation of pro-inflammation positive feedback loop by inducing reactive oxygen species production in endothelial cells. Free Radic Biol Med 2021; 177:404-418.

Abstract
Focal adhesion kinase (FAK) activation plays a crucial role in vascular diseases. In endothelial cells, FAK activation is involved in the activation of pro-inflammatory signaling and the progression of atherosclerosis. Disturbed flow (D-flow) induces endothelial activation and senescence, but the exact role of FAK in D-flow-induced endothelial activation and senescence remains unclear. The objective of this study is to investigate the role of FAK SUMOylation in D-flow-induced endothelial activation and senescence. The results showed that D-flow induced reactive oxygen species (ROS) production via NADPH oxidase activation and activated a redox-sensitive kinase p90RSK, leading to FAK activation by upregulating FAK K152 SUMOylation and the subsequent Vav2 phosphorylation, which in turn formed a positive feedback loop by upregulating ROS production. This feedback loop played a crucial role in regulating endothelial activation and senescence. D-flow-induced endothelial activation and senescence were significantly inhibited by mutating a FAK SUMOylation site lysine152 to arginine. Collectively, we concluded that FAK K152 SUMOylation plays a key role in D-flow-induced endothelial activation and senescence by forming a positive feedback loop through ROS production.

Abstract
Methods for the mechanistic investigations on renal fibrosis have long been concentrated on individual type of cells, such as fibroblasts and epithelial cells. However, in recent years, growing numbers of studies have been shifting toward the role of the intercellular interactions, such as communication between tubular epithelial cells and fibroblasts. Various co-culture models have been utilized in the studies of cell-cell communication and interaction. In this chapter, we describe an innovative co-culture model employing the porous membranes for spatially partitioning the cells while allowing direct crosstalk between fibroblasts and epithelial cells in an effort of mimicking in vivo environment.

Abstract
Kinase drug discovery represents an active area of therapeutic research, with previous pharmaceutical success improving patient outcomes across a wide variety of human diseases. In pancreatic ductal adenocarcinoma (PDAC), innovative pharmaceutical strategies such as kinase targeting have been unable to appreciably increase patient survival. This may be due, in part, to unchecked desmoplastic reactions to pancreatic tumors. Desmoplastic stroma enhances tumor development and progression while simultaneously restricting drug delivery to the tumor cells it protects. Emerging evidence indicates that many of the pathologic fibrotic processes directly or indirectly supporting desmoplasia may be driven by targetable protein tyrosine kinases such as Fyn-related kinase (FRK); B lymphoid kinase (BLK); hemopoietic cell kinase (HCK); ABL proto-oncogene 2 kinase (ABL2); discoidin domain receptor 1 kinase (DDR1); Lck/Yes-related novel kinase (LYN); ephrin receptor A8 kinase (EPHA8); FYN proto-oncogene kinase (FYN); lymphocyte cell-specific kinase (LCK); tec protein kinase (TEC). Herein, we review literature related to these kinases and posit signaling networks, mechanisms, and biochemical relationships by which this group may contribute to PDAC tumor growth and desmoplasia.

Abstract
Pancreatic cancer remains one of the most difficult malignancies to treat. Minimal improvements in patient outcomes and persistently abysmal patient survival rates underscore the great need for new treatment strategies. Currently, there is intense interest in therapeutic strategies that target tyrosine protein kinases. Here, we employed kinome arrays and bioinformatic pipelines capable of identifying differentially active protein tyrosine kinases in different patient-derived pancreatic ductal adenocarcinoma (PDAC) cell lines and wild-type pancreatic tissue to investigate the unique kinomic networks of PDAC samples and posit novel target kinases for pancreatic cancer therapy. Consistent with previously described reports, the resultant peptide-based kinome array profiles identified increased protein tyrosine kinase activity in pancreatic cancer for the following kinases: epidermal growth factor receptor (EGFR), fms related receptor tyrosine kinase 4/vascular endothelial growth factor receptor 3 (FLT4/VEGFR-3), insulin receptor (INSR), ephrin receptor A2 (EPHA2), platelet derived growth factor receptor alpha (PDGFRA), SRC proto-oncogene kinase (SRC), and tyrosine kinase non receptor 2 (TNK2). Furthermore, this study identified increased activity for protein tyrosine kinases with limited prior evidence of differential activity in pancreatic cancer. These protein tyrosine kinases include B lymphoid kinase (BLK), Fyn-related kinase (FRK), Lck/Yes-related novel kinase (LYN), FYN proto-oncogene kinase (FYN), lymphocyte cell-specific kinase (LCK), tec protein kinase (TEC), hemopoietic cell kinase (HCK), ABL proto-oncogene 2 kinase (ABL2), discoidin domain receptor 1 kinase (DDR1), and ephrin receptor A8 kinase (EPHA8). Together, these results support the utility of peptide array kinomic analyses in the generation of potential candidate kinases for future pancreatic cancer therapeutic development.

Mol Med Rep 2020; 22:4619-4628. [PMID: 33173986 PMCID: PMC7646838 DOI: 10.3892/mmr.2020.11556] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2020] [Accepted: 08/25/2020] [Indexed: 11/07/2022] Open
Abstract
Epithelial-mesenchymal transition (EMT) serves an important regulatory role in obstructive nephropathy and renal fibrosis. As an intracellular energy sensor, AMP-activated protein kinase (AMPK) is essential in the process of EMT. The aim of the present study was to elucidate changes in the expression levels of AMPKα2 and which AMPKα2 genes play a role during EMT. TGF-β1 was used to induce EMT in normal rat renal tubular epithelial (NRK-52E) cells. The short hairpin AMPKα2 lentivirus was used to interfere with AMPKα2 expression levels in EMT-derived NRK-52E cells and AMPKα2 expression levels and EMT were detected. Differential gene expression levels following AMPKα2 knockdown in EMT-derived NRK-52E cells were assessed via gene microarray. Potential regulatory pathways were analyzed using ingenuity pathway analysis (IPA) and differentially expressed genes were partially verified by reverse transcription-quantitative PCR (RT-qPCR) and western blotting. AMPKα2 was upregulated in TGF-β1-induced EMT-derived NRK-52E cells. EMT progression was significantly inhibited following downregulation of expression levels of AMPKα2 by shAMPKα2 lentivirus. A total of 1,588 differentially expressed genes were detected following AMPKα2 knockdown in NRK-52E cells in which EMT occurred. The ERK/MAPK pathway was significantly impaired following AMPKα2 knockdown, as indicated by IPA analysis. Furthermore, RT-qPCR and western blot results demonstrated that the expression levels of AMPKα2, v-ets erythroblastosis virus E26 oncogene homolog-1 (ETS1) and ribosomal protein S6 kinase A1 (RPS6KA1) were upregulated following EMT in NRK-52E cells, whereas the expression levels of ETS1 and RPS6KA1 were downregulated following AMPKα2 knockdown. It was concluded that AMPKα2 plays a key role in the regulation of rat renal tubular EMT, which may be achieved by modulating ETS1 and RPS6KA1 in the ERK/MAPK pathway.

Abstract
The kidney injury induced by ischemia-reperfusion (IR) usually comes with irreversible renal fibrosis, a process that develops into chronic kidney disease (CKD), but the underlying cellular mechanism has yet to be determined. To test our hypothesis that exosomes are tightly connected with kidney fibrosis following AKI, we studied the role of exosomes and the transfer of specific miRNA among other genetic components in injured tubular epithelial cells (TECs). We utilized an experimental IR mice model to simulate the fibrotic environment in injured tissue and detect the production of exosomes, and found that exosome deficiency could significantly alleviate the degree of kidney fibrosis following IR administration. MiRNA profiling of exosomes extracted from renal tissue samples with or without ischemia-reperfusion injury (IRI) revealed that miR-150 was markedly increased as a compelling profibrotic molecule, as evidenced by the fact that overexpression of miR-150 facilitated renal fibrosis. Exosomes isolated from hypoxia TECs also induced the increased production of miR-150. In cocultured fibroblasts with TECs-derived exosomes, we confirmed a direct uptake of exosomal miR-150 by fibroblasts. Finally, we verified that in vivo ischemia mice pretreated with exosomes enriched in miR-150 developed more profibrotic manifestations. Thus, our current study indicated that TECs have the ability to employ exosomes to initiate the activation and proliferation of fibroblasts via direct shuttling of miR-150-containing exosomes during reparative responses, and that exosome/miR-150 provides the groundwork for research to develop more personalized therapeutic approaches for controlling tissue fibrosis.
