Abstract
Fungi-derived polyketide-terpenoid hybrids are important meroterpenoid natural products that possess diverse structure scaffolds with a broad spectrum of bioactivities. Herein, we focus on an ever-increasing group of meroterpenoids, orsellinic acid-sesquiterpene hybrids comprised of biosynthetic start unit orsellinic acid coupling to a farnesyl group or/and its modified cyclic products. The review entails the search of China National Knowledge Infrastructure (CNKI), Web of Science, Science Direct, Google Scholar, and PubMed databases up to June 2022. The key terms include "orsellinic acid", "sesquiterpene", "ascochlorin", "ascofuranone", and "Ascochyta viciae", which are combined with the structures of "ascochlorin" and "ascofuranone" drawn by the Reaxys and Scifinder databases. In our search, these orsellinic acid-sesquiterpene hybrids are mainly produced by filamentous fungi. Ascochlorin was the first compound reported in 1968 and isolated from filamentous fungus Ascochyta viciae (synonym: Acremonium egyptiacum; Acremonium sclerotigenum); to date, 71 molecules are discovered from various filamentous fungi inhabiting in a variety of ecological niches. As typical representatives of the hybrid molecules, the biosynthetic pathway of ascofuranone and ascochlorin are discussed. The group of meroterpenoid hybrids exhibits a broad arrange of bioactivities, as highlighted by targeting hDHODH (human dihydroorotate dehydrogenase) inhibition, antitrypanosomal, and antimicrobial activities. This review summarizes the findings related to the structures, fungal sources, bioactivities, and their biosynthesis from 1968 to June 2022.

Abstract
Transforming growth factor-β1 (TGF-β1) plays a premier role in fibrosis. To understand the molecular events underpinning TGF-β1-induced fibrogenesis, we examined the proteomic profiling of a TGF-β1-induced in vitro model of fibrosis in NRK-49F normal rat kidney fibroblasts. Mass spectrometric analysis indicated that 628 cell-lysate proteins enriched in 44 cellular component clusters, 24 biological processes and 27 molecular functions were regulated by TGF-β1. Cell-lysate proteins regulated by TGF-β1 were characterised by increased ribosomal proteins and dysregulated proteins involved in multiple metabolic pathways, including reduced Aldh3a1 and induced Enpp1 and Impdh2, which were validated by enzyme-linked immunosorbent assays (ELISA). In conditioned media, 62 proteins enriched in 20 cellular component clusters, 40 biological processes and 7 molecular functions were regulated by TGF-β1. Secretomic analysis and ELISA uncovered dysregulated collagen degradation regulators (induced PAI-1 and reduced Mmp3), collagen crosslinker (induced Plod2), signalling molecules (induced Ccn1, Ccn2 and Tsku, and reduced Ccn3) and chemokines (induced Ccl2 and Ccl7) in the TGF-β1 group. We conclude that TGF-β1-induced fibrogenesis in renal fibroblasts is an intracellular metabolic disorder and is inherently coupled with inflammation mediated by chemokines. Proteomic profiling established in this project may guide development of novel anti-fibrotic therapies in a network pharmacology approach.

Silibinin Ameliorates O-GlcNAcylation and Inflammation in a Mouse Model of Nonalcoholic Steatohepatitis. Int J Mol Sci 2018; 19:ijms19082165. [PMID: 30042374 PMCID: PMC6121629 DOI: 10.3390/ijms19082165] [Citation(s) in RCA: 16] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2018] [Revised: 07/13/2018] [Accepted: 07/19/2018] [Indexed: 02/06/2023] Open
Abstract
The mechanisms underlying the progression to non-alcoholic steatohepatitis (NASH) remain to be elucidated. In the present study, we aimed to identify the proteins involved in the pathogenesis of liver tissue inflammation and to investigate the effects of silibinin, a natural polyphenolic flavonoid, on steatohepatitis. We performed comparative proteomic analysis using methionine and choline-deficient (MCD) diet-induced NASH model mice. Eighteen proteins were identified from the two-dimensional proteomic analysis, which are not only differentially expressed, but also significantly improved, by silibinin treatment. Interestingly, seven of these proteins, including keratin cytoskeletal 8 and 18, peroxiredoxin-4, and protein disulfide isomerase, are known to undergo GlcNAcylation modification, most of which are related to structural and stress-related proteins in NASH model animals. Thus, we primarily focused on how the GlcNAc modification of these proteins is involved in the progression to NASH. Remarkably, silibinin treatment alleviates the severity of hepatic inflammation along with O-GlcNAcylation in steatohepatitis. In particular, the reduction of inflammation by silibinin is due to the inhibition of the O-GlcNAcylation-dependent NF-κB-signaling pathway. Therefore, silibinin is a promising therapeutic agent for hyper-O-GlcNAcylation as well as NASH.

Proteomic analysis of mice fed methionine and choline deficient diet reveals marker proteins associated with steatohepatitis. PLoS One 2015; 10:e0120577.

Abstract
The mechanisms underlying the progression of simple steatosis to steatohepatitis are yet to be elucidated. To identify the proteins involved in the development of liver tissue inflammation, we performed comparative proteomic analysis of non-alcoholic steatohepatitis (NASH). Mice fed a methionine and choline deficient diet (MCD) developed hepatic steatosis characterized by increased free fatty acid (FFA) and triglyceride levels as well as alpha-SMA. Two-dimensional proteomic analysis revealed that the change from the normal diet to the MCD diet affected the expressions of 50 proteins. The most-pronounced changes were observed in the expression of proteins involved in Met metabolism and oxidative stress, most of which were significantly downregulated in NASH model animals. Peroxiredoxin (Prx) is the most interesting among the modulated proteins identified in this study. In particular, cross-regulated Prx1 and Prx6 are likely to participate in cellular defense against the development of hepatitis. Thus, these Prx isoforms may be a useful new marker for early stage steatohepatitis. Moreover, curcumin treatment results in alleviation of the severity of hepatic inflammation in steatohepatitis. Notably, curcumin administration in MCD-fed mice dramatically reduced CYP2E1 as well as Prx1 expression, while upregulating Prx6 expression. These findings suggest that curcumin may have a protective role against MCD fed-induced oxidative stress.

Diabetologia 2013; 56:1174-82. [PMID: 23370527 DOI: 10.1007/s00125-013-2835-y] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/10/2012] [Accepted: 01/04/2013] [Indexed: 01/17/2023]
Abstract
AIM/HYPOTHESIS This study aimed to determine the interaction between the EGF receptor (EGFR) and peroxisome proliferator-activated receptor γ (PPARγ) and the role of EGFR in sodium and water transport in the proximal tubule. METHODS Primary human proximal tubule cells (PTCs) were exposed to high glucose in the presence and absence of pioglitazone. Total and phospho-EGFR levels and EGFR mRNA expression were determined by western blot and real-time PCR, respectively. Sodium-hydrogen exchanger-3 (NHE3), PPARγ and aquaporin 1 (AQP1) levels were determined by western blot. The role of EGFR was elucidated using the EGFR tyrosine kinase inhibitor, PKI166. The role of PPARγ in high-glucose conditions was determined using specific PPARγ small interfering (si)RNA. P-EGFR, PPARγ, AQP1 and NHE3 production in a rat model of diabetes (streptozotocin-induced hypertensive Ren-2 transgenic [mRen2]27 rats) and controls, with or without pioglitazone treatment, was determined by immunohistochemistry. The PPARγ and EGFR interaction was determined by chromatin immunoprecipitation assay, and the effect of pioglitazone on EGFR activation by luciferase assay. RESULTS PTCs exposed to both high glucose and pioglitazone increased protein abundance of P-EGFR, NHE3, AQP1 and PPARγ. Pioglitazone-induced upregulation of NHE3 and AQP1 was abolished by PKI166. High-glucose-induced increases in P-EGFR, NHE3 and AQP1 were decreased with PPARγ siRNA. AQP1 and NHE3 but not PPARγ were increased in a diabetic rat model and further increased by pioglitazone treatment. Pioglitazone induced PPARγ binding to the EGFR promoter and subsequent downstream activation. CONCLUSIONS/INTERPRETATION Our data suggest that EGFR activation mediates PPARγ-induced sodium and water reabsorption via upregulation of NHE3 and AQP1 channels in the proximal tubule. EGFR inhibition may be a therapeutic strategy in the treatment of diabetic nephropathy and in limiting salt and water retention, which currently restricts the use of PPARγ agonists.

Abstract
Transforming growth factor-β (TGF-β), TGF-β receptor (TGF-βR), and epidermal growth factor receptor (EGFR) are important in the pathogenesis of kidney fibrosis, a result of renal fibroblast activation. The EGFR kinase inhibitor gefitinib attenuates glomerular fibrosis in hypertensive rats whereas dominant-negative EGFR attenuates interstitial fibrosis in mouse with acute renal ischemia. Thus, we studied the effects and molecular mechanisms of gefitinib in TGF-β1-induced mitogenesis and collagen production in normal rat kidney interstitial fibroblast (NRK-49F) cells. We found that TGF-β1 increased cell mitogenesis. TGF-β1 also time-dependently increased cyclin D1 protein expression. TGF-β1 rapidly transactivated EGFR. SB431542 (a type I TGF-βR kinase inhibitor) and SB203580 (a p38 kinase inhibitor) attenuated TGF-β1-induced phosphorylation of Smad2/3 protein. SB431542 and gefitinib attenuated TGF-β1-induced phosphorylation of ERK1/2 and p38 kinase. SB431542 and gefitinib also attenuated TGF-β1-induced cyclin D1 protein expression. Moreover, SB431542, gefitinib, PD98059 (an ERK1/2 inhibitor), and SB203580 attenuated TGF-β1-induced cell mitogenesis. Finally, SB431542 and gefitinib attenuated TGF-β1-induced collagen production. We concluded that gefitinib attenuates TGF-β1-induced cell mitogenesis via the EGFR-ERK1/2/p38 kinase pathway in NRK-49F cells. Moreover, gefitinib attenuates TGF-β1-induced cyclin D1 protein expression and collagen production. Thus, gefitinib attenuates TGF-β1-induced mitogenesis and collagen production in vitro.

Abstract
Renal tubulo-interstitial fibrosis is a non-specific process, representing the final common pathway for all kidney diseases, irrespective of their initial cause, histological injury, or etiology, leading to gradual expansion of the fibrotic mass which destroys the normal structure of the tissue and results in organ dysfunction and, ultimately, in end-stage organ failure. Proteomic studies of the fibrotic pathophysiological mechanisms have been performed in cell cultures, animal models and human tissues, addressing some of the key issues. This article will review proteomic contribution to the raising current knowledge on renal fibrosis biology and also mention seminal open questions to which proteomic techniques and proteomists could fruitfully contribute.
