Abstract
Fibrosis is a common pathological process that can affect virtually all the organs, but there are hardly any effective therapeutic options. This has led to an intense search for antifibrotic therapies over the last decades, with a great number of clinical assays currently underway. We have systematically reviewed all current and recently finished clinical trials involved in the development of new antifibrotic drugs, and the preclinical studies analyzing the relevance of each of these pharmacological strategies in fibrotic processes affecting tissues beyond those being clinically studied. We analyze and discuss this information with the aim of determining the most promising options and the feasibility of extending their therapeutic value as antifibrotic agents to other fibrotic conditions.

Drug Targeting and Nanomedicine: Lessons Learned from Liver Targeting and Opportunities for Drug Innovation. Pharmaceutics 2022; 14:pharmaceutics14010217. [PMID: 35057111 PMCID: PMC8777931 DOI: 10.3390/pharmaceutics14010217] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2021] [Revised: 12/23/2021] [Accepted: 12/24/2021] [Indexed: 02/08/2023] Open
Abstract
Drug targeting and nanomedicine are different strategies for improving the delivery of drugs to their target. Several antibodies, immuno-drug conjugates and nanomedicines are already approved and used in clinics, demonstrating the potential of such approaches, including the recent examples of the DNA- and RNA-based vaccines against COVID-19 infections. Nevertheless, targeting remains a major challenge in drug delivery and different aspects of how these objects are processed at organism and cell level still remain unclear, hampering the further development of efficient targeted drugs. In this review, we compare properties and advantages of smaller targeted drug constructs on the one hand, and larger nanomedicines carrying higher drug payload on the other hand. With examples from ongoing research in our Department and experiences from drug delivery to liver fibrosis, we illustrate opportunities in drug targeting and nanomedicine and current challenges that the field needs to address in order to further improve their success.

Lenvatinib prevents liver fibrosis by inhibiting hepatic stellate cell activation and sinusoidal capillarization in experimental liver fibrosis. J Cell Mol Med 2021; 25:4001-4013.

Abstract
Molecular targeted agents are pharmacologically used to treat liver fibrosis and have gained increased attention. The present study examined the preventive effect of lenvatinib on experimental liver fibrosis and sinusoidal capillarization as well as the in vitro phenotypes of hepatic stellate cells. LX-2, a human stellate cell line, was used for in vitro studies. In vivo liver fibrosis was induced in F344 rats using carbon tetrachloride by intraperitoneal injection for 8 weeks, and oral administration of lenvatinib was started two weeks after initial injection of carbon tetrachloride. Lenvatinib restrained proliferation and promoted apoptosis of LX-2 with suppressed phosphorylation of extracellular signal-regulated kinase 1/2 and AKT. It also down-regulated COL1A1, ACTA2 and TGFB1 expressions by inhibiting the transforming growth factor-β1/Smad2/3 pathway. Treatment with lenvatinib also suppressed platelet-derived growth factor-BB-stimulated proliferation, chemotaxis and vascular endothelial growth factor-A production, as well as basic fibroblast growth factor-induced LX-2 proliferation. In vivo study showed that lenvatinib attenuated liver fibrosis development with reduction in activated hepatic stellate cells and mRNA expression of profibrogenic markers. Intrahepatic neovascularization was ameliorated with reduced hepatic expressions of Vegf1, Vegf2 and Vegfa in lenvatinib-treated rats. Collectively, these results suggest the potential use of lenvatinib as a novel therapeutic strategy for liver fibrosis.

Abstract
Liver fibrosis is a global health problem currently without clinically approved drugs. It is characterized by the excessive accumulation of extracellular matrix (ECM) mainly produced by activated hepatic stellate cells (HSCs). Uncovering the mechanisms underlying the fibrogenic responses in HSCs may have profound translational implications. Erythropoietin-producing hepatocellular receptor B2 (EphB2) is a receptor tyrosine kinase that has been indicated to be a novel profibrotic factor involved in liver fibrogenesis. In the present study, we investigated the effects of miR-451 and miR-185 on the expression of EphB2 and their roles in liver fibrogenesis both in vitro and in vivo. We found that EphB2 upregulation is a direct downstream molecular event of decreased expression of miR-451 and miR-185 in the process of liver fibrosis. Moreover, miR-451 was unexpectedly found to upregulate miR-185 expression at the post-transcriptional level by directly targeting the nuclear export receptor exportin 1 (XPO-1) and synergistically suppress HSCs activation with miR-185. To investigate the clinical potential of these miRNAs, miR-451/miR-185 agomirs were injected individually or jointly into CCl4-treated mice. The results showed that coadministration of these agomirs synergistically alleviated liver fibrosis in vivo. These findings indicate that miR-451 and miR-451/XPO-1/miR-185 axis play important and synergistic regulatory roles in hepatic fibrosis partly through co-targeting EphB2, which provides a novel therapeutic strategy for the treatment of hepatic fibrosis.

Abstract
Abstract
Purpose of Review
Treatment of liver fibrosis benefits from hepatic stellate cell (HSC)-specific delivery. Since the description of first carrier to HSC, many developments have taken place in this area. The purpose is to give an overview of the different carriers and homing moieties that are available for HSC targeting and illustrate the opportunities and hurdles they provide.
Recent Findings
There is a growing number of homing devices to deliver drugs to HSC, and options to deliver siRNA to HSC have emerged. Other developments include controlling corona formation, development of linker technology, and design of theranostic approaches. We are on the eve of reaching the clinic with innovative HSC-specific compounds.
Summary
An overview of different core molecules is presented together with an overview of targeting strategies toward different receptors on HSC, providing a versatile toolbox. Many therapeutics, ranging from small chemical entities and proteins to RNA- or DNA-modulating substances, have already been incorporated in these constructs in the recent years.

Abstract
As hepatic stellate cells (HSCs) are essential for hepatic fibrogenesis, HSCs targeted nano-drug delivery system is a research hotspot in liver fibrosis therapy. However, the excessive deposition of fibrosis collagen (mainly collagen I) in the space of Disse associated with hepatic fibrogenesis would significantly hinder nano-formulation delivery to HSCs. Here, we have prepared a collagenase I and retinol co-decorated polymeric micelle that possess nanodrill-like and HSCs-target function based on poly-(lactic-co-glycolic)-b-poly (ethylene glycol)-maleimide (PLGA-PEG-Mal) (named CRM) for liver fibrosis therapy. Upon encountering collagen I barrier, CRM exerted a nanodrill-like function, efficiently degrading pericellular collagen I and showing greater uptake by human HSCs than other micelle formulations. Besides, CRM could realize excellent accumulation in the fibrotic liver and accurate targeting to activated HSCs in mouse hepatic fibrosis model. Moreover, CRM loaded with nilotinib (CRM/NIL), a second-generation tyrosine kinase inhibitor used in the treatment of liver fibrosis, showed optimal antifibrotic activity. This work suggests that CRM with dual function is an efficient carrier for liver fibrosis drug delivery and collagenase I decorating could be a new strategy for building more efficient HSCs targeted nano-drug delivery system.

Abstract
It has been shown that both nilotinib as a tyrosine kinase inhibitor, and atorvastatin as a rho-kinase inhibitor, have antifibrotic effects. Therefore, considering the relationship between these two pathways, this study aimed to investigate the effects of their co-treatment against hepatic stellate cells (HSCs) activation and liver fibrosis. For this purpose, the activation of HSCs coincided with these therapies. Also, liver fibrosis by carbon tetrachloride (CCl4 ) was induced in male Wistar rats and treated simultaneously with these compounds. The expression of alpha-smooth muscle actin (α-SMA), connective tissue growth factor (CTGF), Ras homolog gene family, and member A (RhoA)/Rho-associated protein kinase (ROCK) in HSCs were measured. The expression of transforming growth factor beta-1 (TGF-β1), its receptor (TβRII), CTGF, and platelets derived growth factor (PDGF), in the livers, were also investigated, all by real-time PCR and western blot analysis. Also, histopathologic and immunohistochemical evaluations were performed to evaluate changes in liver fibrosis during treatment. The results indicated the down-regulation of RhoA/ROCK, CTGF, and α-SMA, and inhibition of the HSCs activation toward myofibroblasts. The results also showed that the combined use of atorvastatin and nilotinib has significantly higher inhibitory effects. The antifibrotic effects of atorvastatin and nilotinib co-administration were also observed by histopathologic and immunohistochemical observations, and inhibiting the expression of TGF-β1, TβRII, CTGF, and PDGF. Taken together, this study revealed that co-administration of nilotinib-atorvastatin has novel antifibrotic effects, by inhibiting RhoA/ROCK, and CTGF pathway. Therefore, the importance of the common pathway of RhoA/ROCK and CTGF, in reducing fibrosis may almost be concluded.

Abstract
Hepatic stellate cells (HSCs) are the primary cell type responsible for liver fibrogenesis. Transforming growth factor beta 1 (TGF-β1) and platelet-derived growth factor (PDGF) are key profibrotic cytokines that regulate HSC activation and proliferation with functional convergence. Dual RNA interference against their receptors may achieve therapeutic effects. A novel RNAi strategy based on HSC-specific GFAP promoter-driven and lentiviral-expressed artificial microRNAs (amiRNAs) was devised that consists of an microRNA-30a backbone and effective shRNAs against mouse Pdgfrβ and Tgfbr2. Then, its antifibrotic efficacy was tested in primary and cultured HSCs and in mice affected with carbon tetrachloride-induced hepatic fibrosis. The study shows that amiRNA-mediated Pdgfrβ and Tgfbr2 co-silencing inhibits HSC activation and proliferation. After recombinant lentiviral particles were delivered into the liver via tail-vein injection, therapeutic amiRNAs were preferentially expressed in HSCs and efficiently co-knocked down in situ Tgfbr2 and Pdgfrβ expression, which correlates with downregulated expression of target or effector genes of their signaling, which include Pai-1, P70S6K, and D-cyclins. amiRNA-based HSC-specific co-silencing of Tgfbr2 and Pdgfrβ significantly suppressed hepatic expression of fibrotic markers α-Sma and Col1a1, extracellular matrix regulators Mmps and Timp1, and phenotypically ameliorated liver fibrosis, as indicated by reductions in serum alanine aminotransferase activity, collagen deposition, and α-Sma-positive staining. The findings provide proof of concept for the use of amiRNA-mediated co-silencing of two profibrogenic pathways in liver fibrosis treatment and highlight the therapeutic potential of concatenated amiRNAs for gene therapy.

Abstract
Previous studies have demonstrated that the recombinant Schistosoma japonicum protein P40 (rSjP40) could inhibit activation of hepatic stellate cells (HSCs) through the TGF-β1/Smads signaling pathway. Since multiple microRNAs could play essential roles in HSC activation and in the process of hepatic fibrosis through targeting Smads, we attempted to seek the potential microRNAs that could be involved in rSjP40-induced inhibition of HSC activation. Using the method of quantitative real-time PCR, we found that rSjP40 could induce miR-146a expression in LX-2 cells. The down-regulated expression levels of Smad4 and α-SMA in LX-2 cells induced by rSjP40 were partially restored by an miR-146a inhibitor. miR-146a can be involved in rSjP40-induced inhibition of HSC activation through targeting Smad4. These findings provide us a new idea to explore the potential mechanisms by which rSjP40 could regulate the process of hepatic fibrosis.

Abstract
The non-selectivity of tyrosine kinase inhibitors is the leading cause of drug withdrawals, and limits their application in anti-fibrosis. The role of Src tyrosine kinase Lyn in hepatic fibrosis remains elusive. In this study, we aimed to elucidate the role of Lyn kinase in the pathogenesis of hepatic fibrosis. Through examining Lyn-transgenic (Lyn TG) mice treated with CCl4 (carbon tetrachloride), we determined whether Lyn kinase is involved in the pathogenesis of hepatic fibrosis. On top of that, we also investigated the role of Lyn in the activation of hepatic stellate cells (HSCs) in vitro. Here, we showed that Lyn kinase was highly expressed in liver fibrosis upon CCl4 treatment. Meanwhile, Lyn TG mice showed that perivascular infiltration of mononuclear cells, and the markers of liver injury and hepatocytes apoptosis were significantly increased in liver tissue after CCl4 treatment. In comparison with wild-type (WT) mice after CCl4 treatment, we found that the fibrotic score in liver tissues of Lyn TG mice with the same treatment went up dramatically, so did the gene expression of fibrotic markers. In addition, over-expression of Lyn kinase drastically promoted the expression of HSCs activation markers in vivo or in vitro. Additionally, the Src-specific inhibitor PP2 significantly suppressed the increased expression of integrin αvβ3 in TGF-β1-induced HSCs, and PP2 further induced HSC apoptosis in TGF-β1-treated cells. These results collectively indicated that Lyn kinase is implicated in the pathogenesis of hepatic fibrosis through the modulating of HSC activation.
