J Biochem Mol Toxicol 2022; 36:e23149. [PMID: 35712856 DOI: 10.1002/jbt.23149] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2021] [Revised: 03/05/2022] [Accepted: 05/30/2022] [Indexed: 11/08/2022]
Abstract
Hepatic fibrosis (HF), a continuous wound-healing response of the liver to repeated injuries, is characterized by abnormal extracellular matrix (ECM) accumulation. Hepatic stellate cells (HSCs) are considered a major cell type for ECM production. However, recent evidence indicates the lack of effective treatments for HF. Hesperetin, a Traditional Chinese Medicine monomer, has been isolated from the fruit peel of Citrusaurantium L. (Rutaceae). Growing evidence suggests the partial function of hesperetin in HF treatment. A hesperetin derivative (HD) was synthesized in our laboratory to increase the bioavailability and the water solubility of hesperetin. In this study, we detected the functions of HD in a mouse model of CCl4 -induced HF and transforming growth factor-β1-stimulated HSC-T6 cells, in vivo and in vitro. HD reduced histological damage and CCl4 -induced HF. Moreover, HD interference was associated with the activation of indicators in HSC-T6 cells, showing that HD is involved in HSCs activation in HF. Mechanistically, the Hedgehog pathway is involved in the HD treatment of HF, and HD may attenuate the aberrant expression of patched1. In conclusion, the studies indicate that HD may function as a potential antifibrotic Traditional Chinese Medicine monomer in HF therapy.

Abstract
Emerging epidemic-prone diseases have introduced numerous health and economic challenges in recent years. Given current knowledge of COVID-19, herd immunity through vaccines alone is unlikely. In addition, vaccination of the global population is an ongoing challenge. Besides, the questions regarding the prevalence and the timing of immunization are still under investigation. Therefore, medical treatment remains essential in the management of COVID-19. Herein, recent advances from beginning observations of COVID-19 outbreak to an understanding of the essential factors contributing to the spread and transmission of COVID-19 and its treatment are reviewed. Furthermore, an in-depth discussion on the epidemiological aspects, clinical symptoms and most efficient medical treatment strategies to mitigate the mortality and spread rates of COVID-19 is presented.

Abstract
The initial immune response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) includes an interferon-dependent antiviral response. A late and uncontrolled inflammatory response characterized by high activity of proinflammatory cytokines and the recruitment of neutrophils and macrophages develops in predisposed individuals and is potentially harmful in some cases. Interleukin (IL)-17 is one of the many cytokines released during coronavirus disease 2019 (COVID-19). IL-17 is crucial in recruiting and activating neutrophils, cells that can migrate to the lung, and are heavily involved in the pathogenesis of COVID-19. During the infection T helper 17 (Th17) cells and IL-17-related pathways are associated with a worse outcome of the disease. All these have practical consequences considering that some drugs with therapeutic targets related to the Th17 response may have a beneficial effect on patients with SARS-CoV-2 infection. Herein, we present the arguments underlying our assumption that blocking the IL-23/IL-17 axis using targeted biological therapies as well as drugs that act indirectly on this pathway such as convalescent plasma therapy and colchicine may be good therapeutic options.

Abstract
Hepatic fibrosis, a common pathological feature and leading cause of various chronic liver diseases, still lacks effective therapy. Hesperetin derivative (HD) is a derivative of Traditional Chinese Medicine monomer isolated from the fruit peel of Citrusaurantium L. (Rutaceae). In the present study, we revealed the anti-fibrotic effects of HD in CCl4-induced mouse hepatic fibrosis model and in TGF-β1-activated LX-2 cells, in vivo and in vitro. Results showed that HD prevented CCl4-induced liver injury and histological damage. Consistently, HD inhibited the up-regulation of liver fibrogenesis markers α-SMA, Col1α1, Col3α1 and TIMP-1 in primary hepatic stellate cells (HSCs) and suppressed inflammatory responses in primary liver macrophages from hepatic fibrosis mice. Furthermore, HD promoted the apoptosis of activated HSCs, a key step in the onset of fibrosis regression. Mechanistically, the Hedgehog pathway was involved in HD-treated hepatic fibrosis, and HD specifically contributed to attenuate the aberrant expression of Glioma associated oncogene-1 (Gli-1). Interestingly, blockade of Gli-1 removed the inhibitory effect of HD on activated HSCs, indicating that Gli-1 may play a pivotal role in mediating the anti-fibrotic effect of HD in hepatic fibrosis. Collectively, our results suggest that HD may be a potential anti-fibrotic Traditional Chinese Medicine monomer for the treatment of hepatic fibrosis.

Protective Effects of Amarogentin against Carbon Tetrachloride-Induced Liver Fibrosis in Mice. Molecules 2017; 22:molecules22050754.

Abstract
Amarogentin, a secoiridoid glycoside that is mainly extracted from Swertia and Gentiana roots, has been suggested to exhibit many biological effects, including anti-oxidative, anti-tumour, and anti-diabetic activities. The present study was designed to evaluate the protective effects of amarogentin on carbon tetrachloride-induced liver fibrosis in vivo and the underlying mechanism. Fibrosis was induced by subcutaneous injections of 6 mL/kg of 20% carbon tetrachloride (dissolved in olive oil) twice per week for seven weeks. Mice were orally treated with 25, 50, and 100 mg/kg amarogentin and with colchicine as a positive control. Biochemical assays and histopathological investigations showed that amarogentin delayed the formation of liver fibrosis; decreased alanine aminotransferase, aspartate aminotransferase, malondialdehyde and hydroxyproline levels; and increased albumin, cyclic guanosine monophosphate, glutathione peroxidase, and superoxide dismutase levels. Moreover, amarogentin exhibited downregulation of α-smooth muscle actin and transforming growth factor-β₁ levels in immunohistochemical and Western blot analyses. The levels of phosphorylated extracellular regulated protein kinases, c-Jun N-terminal kinase, and p38 were also significantly reduced in all amarogentin-treated groups in a dose-dependent manner. These findings demonstrated that amarogentin exerted significant hepatoprotective effects against carbon tetrachloride-induced liver fibrosis in mice and suggested that the effect of amarogentin against liver fibrosis may be by anti-oxidative properties and suppressing the mitogen-activated protein kinase signalling pathway.

Abstract
AIM: To test whether colchicine would be an effective antifibrotic agent for treatment of chronic liver diseases in patients who could not be treated with α-interferon.
METHODS: Seventy-four patients (46 males, 28 females) aged 40-66 years (mean 53 ± 13 years) participated in the study. The patients were affected by chronic liver diseases with cirrhosis which was proven histologically (n = 58); by chronic active hepatitis C (n = 4), chronic active hepatitis B (n = 2), and chronic persistent hepatitis C (n = 6). In the four patients lacking histology, cirrhosis was diagnosed from anamnesis, serum laboratory tests, esophageal varices and ascites. Patients were assigned to colchicine (1 mg/d) or standard treatment as control in a randomized, double-blind trial, and followed for 4.4 years with clinical and laboratory evaluation.
RESULTS: Survival at the end of the study was 94.6% in the colchicine group and 78.4% in the control group (P = 0.001). Serum N-terminal peptide of type III procollagen levels fell from 34.0 to 18.3 ng/mL (P = 0.0001), and pseudocholinesterase levels rose from 4.900 to 5.610 mU/mL (P = 0.0001) in the colchicine group, while no significant change was seen in controls. Best results were obtained in patients with chronic hepatitis C and in alcoholic cirrhotics.
CONCLUSION: Colchicine is an effective and safe antifibrotic drug for long-term treatment of chronic liver disease in which fibrosis progresses towards cirrhosis.

Abstract
Hepatitis C virus (HCV) infection is an important public health issue worldwide. It is estimated that over 170 million people are infected with the virus. The present study reports six cases in which patients did not respond to combination therapy with pegylated interferon and ribavirin. However, after the addition of thalidomide to the therapy, the patients presented negative RNA PCR. The use of thalidomide combined with pegylated interferon and ribavirin for the treatment of hepatitis C is described here for the first time in the related literature.

Abstract
AIM: We studied the effect of colchicine combined with radiation on the survival of human hepatocellular carcinoma (HCC) HA22T/VGH cells.
METHODS: Twenty-four hours after treatment with 0-8 ng/mL colchicine, HA22T/VGH cells were irradiated at various doses (0, 1, 2, 4, and 8 Gy). Colony assay was performed to assess the surviving cell fraction. Survival curves were fitted by using a linear-quadratic model to estimate the sensitizer enhancement ratio (SER). Flow cytometry was used for cell cycle analysis.
RESULTS: Colchicine at lower concentrations (1 and 2 ng/mL) had obvious synergy with radiation to inhibit HCC cell growth, whereas higher concentrations (4 and 8 ng/mL) had only additive effect to radiation. Pretreatment with 1 and 2 ng/mL colchicine for 24-h enhanced cell killing by radiation with SERs of 1.21 and 1.53, respectively. G2/M arrest was only observed with higher colchicine doses (8 and 16 ng/mL) after 24-h treatment; this effect was neither seen with lower doses (1, 2, and 4 ng/mL) nor with any dose after only 1 h of treatment.
CONCLUSION: Our results suggest that colchicine has potential as an adjunct to radiotherapy for HCC treatment. Lower doses of colchicine possess radiosensitizing effects via some mechanism other than G2/M arrest. Further study is necessary to elucidate the mechanism.

Abstract
BACKGROUND Alcohol and hepatotropic viruses cause the majority of liver cirrhosis cases in the Western World. Colchicine is an anti-inflammatory and anti-fibrotic medication. Several randomised clinical trials have addressed the question whether colchicine has any efficacy in patients with alcoholic or non-alcoholic fibrosis and cirrhosis. OBJECTIVES To assess the beneficial and harmful effects of colchicine in patients with alcoholic or non-alcoholic fibrosis or cirrhosis, excluding primary biliary cirrhosis. SEARCH STRATEGY The Cochrane Hepato-Biliary Group Controlled Trials Register, The Cochrane Controlled Trials Register on The Cochrane Library, MEDLINE, EMBASE, Web of Science, and full text searches were combined (September 2004). Manufacturers and researchers in the field were also contacted. SELECTION CRITERIA We included randomised trials irrespective of blinding, language, or publication status comparing per oral colchicine with placebo or no intervention for patients with fibrosis or cirrhosis induced by either alcohol, virus, or unknown factors (cryptogenic). DATA COLLECTION AND ANALYSIS The statistical package (RevMan Analyses) provided by The Cochrane Collaboration was used. The methodological quality of the randomised clinical trials was evaluated. MAIN RESULTS We could include fifteen randomised clinical trials in which 1714 patients were randomised. We found no significant effects of colchicine on mortality (relative risks (RR) 1.00, 95% confidence interval (CI) 0.87 to 1.16), liver-related mortality (RR 1.08, 95% CI 0.88 to 1.33), complications (RR 1.01, 95% CI 0.74 to 1.38), liver biochemistry, liver histology, and alcohol consumption (RR 1.03, 95% CI 0.77 to 1.39). Colchicine was associated with a significantly increased risk of adverse events (RR 4.35, 95% CI 2.16 to 8.77). AUTHORS' CONCLUSIONS Colchicine should not be used for alcoholic, viral, or cryptogenic liver fibrosis or liver cirrhosis outside randomised clinical trials.

Abstract
BACKGROUND Colchicine, an inhibitor of collagen synthesis, has been suggested as potentially beneficial in cirrhosis. OBJECTIVE This long-term, randomized, double blind, placebo controlled trial was conducted in order to evaluate the efficacy of colchicine in alcoholic cirrhosis. METHODS Ambulatory patients with biopsy proven alcoholic cirrhosis, presenting from 1989 to 1997, with no exclusion criteria (e.g. Child-Pugh C, bilirubin > 10 mg/dl and gastrointestinal bleeding in the previous 15 days), were randomized to receive orally, 5 days/week, 1 mg/day of colchicine or placebo. MAIN OUTCOME MEASURES Results were analysed on an intention to treat basis, for survival, incidence of complications, biochemical liver tests and safety. RESULTS Twenty-nine patients received colchicine and 26 placebo; characteristics of both groups were similar. The median follow-up was 40.6 (1.4-126.3) months in the colchicine versus 42.4 (5.7-118.2) months in the placebo group (NS). No significant side effects were reported. During follow-up, there were no significant differences in compliance and alcohol abstinence (86% vs 85%). Overall survival was not statistically different (P = 0.38). Cumulative 3-year survival rates were 74.9% in the colchicine versus 91.4% in placebo group (NS). The annual incidence rate of complications was similar with colchicine or placebo: gastrointestinal bleeding, 1.5% vs 1.2%; ascites, 3.7% vs 3.7%; and encephalopathy, 1.0% vs 0.9%. The comparison of changes in biochemical parameters between groups did not show any significant difference. CONCLUSIONS Although well tolerated, colchicine does not appear to overcome the progression and natural history of long-established alcoholic cirrhosis.

Abstract
BACKGROUND The majority of liver fibrosis and liver cirrhosis cases in the Western World is caused by alcohol and hepatotoxic viruses. Colchicine is an anti-inflammatory and anti-fibrotic medication. Several randomised clinical trials have addressed the question whether colchicine has any efficacy in patients with alcoholic as well as non-alcoholic fibrosis and cirrhosis. OBJECTIVES The objectives were to assess the efficacy of colchicine on mortality, clinical symptoms and complications, liver biochemistry, liver fibrosis markers, liver histology, alcohol consumption, quality of life, and health economics in patients with alcoholic and non-alcoholic fibrosis or cirrhosis, excluding primary biliary cirrhosis and other rarer forms of fibrosis/cirrhosis. Also adverse events were assessed. SEARCH STRATEGY The Cochrane Hepato-Biliary Group Controlled Trials Register, The Cochrane Library, MEDLINE, and full text searches were combined. SELECTION CRITERIA Only randomised clinical trials were included studying patients with alcoholic fibrosis, alcoholic hepatitis and/or alcoholic cirrhosis as well as patients with viral induced or cryptogenic fibrosis and/or cirrhosis according to the diagnostic work-up of the individual trial. Interventions encompassed peroral colchicine at any dose versus placebo or no intervention. The trials could be double-blind, single-blind or unblinded. The trials could be unpublished or published and no language limitations were applied. DATA COLLECTION AND ANALYSIS All analyses were performed according to the intention-to-treat method. The statistical package (RevMan and MetaView) provided by the Cochrane Collaboration was used. The methodological quality of the randomised clinical trials was evaluated by the Jadad-scale. MAIN RESULTS Combining the results of 14 randomised clinical trials including 1150 patients demonstrated no significant effects of colchicine on mortality (Peto odds ratio (OR) 0.90, 95% confidence interval (CI) 0.63 to 1.29), liver related mortality (OR 1.05, 95% CI 0.61 to 1.80), complications (OR 1.01, 95% CI 0.63 to 1.62), liver biochemistry, liver histology, and alcohol consumption (OR 1.02, 95% CI 0.58 to 1.79). Colchicine was associated with a significantly increased risk of adverse events (OR 4.92, 95% CI 2.66 to 9.10; P< 0.001). REVIEWER'S CONCLUSIONS Colchicine should not be used for alcoholic, viral, or cryptogenic liver fibrosis or liver cirrhosis outside randomised trials.

Abstract
BACKGROUND The prognosis of chronic hepatitis depends on the progression of hepatic fibrosis. AIM To investigate whether the antifibrotic drug colchicine, in combination with interferon-alpha has a role in the treatment of chronic hepatitis C. METHODS Sixty-five HCV-RNA positive patients with chronic hepatitis were randomized to receive interferon-alpha, 6 MU t.i.w. for 6 months followed by 3 MU t.i.w. for further 6 months, with or without the adjunct of colchicine, 1 mg o.d., 6 days a week, for 3 years. We report an interim analysis after the first 18 months. RESULTS Thirty-four patients received interferon-alpha and 31 received interferon-alpha and colchicine. The two groups were comparable for baseline data, including HCV-RNA levels, genotypes and histological grading/staging. Drop-outs and side-effects were similar. The proportion of patients who achieved alanine transaminase normalization or undetectable HCV-RNA at month 6 was higher in the interferon-alpha (68% and 47%, respectively) than in the interferon-alpha plus colchicine group (32% and 23%, P=0.004 and P=0. 04, respectively). End-of-treatment biochemical and virological response occurred in 41% and 29% of the interferon-alpha and 19% and 10% of the combination group, respectively (P=0.05 and P=0.05). Sustained biochemical response occurred in 26% of the interferon-alpha and 6% of the interferon-alpha plus colchicine group (P=0.03), corresponding percentages of sustained HCV-RNA loss being 21% and 3% (P=0.04). CONCLUSIONS The combination of colchicine and interferon-alpha worsens the effectiveness of interferon-alpha alone in HCV chronic hepatitis. These alarming findings prompted us to interrupt the trial at this stage.

Abstract
The mammalian cell cytoskeleton consists of a diverse group of fibrillar elements that play a pivotal role in mediating a number of digestive and nondigestive cell functions, including secretion, absorption, motility, mechanical integrity, and mitosis. The cytoskeleton of higher-eukaryotic cells consists of three highly abundant major protein families: microfilaments (MF), microtubules (MT), and intermediate filaments (IF), as well as a growing number of associated proteins. Within digestive epithelia, the prototype members of these three protein families are actins, tubulins, and keratins, respectively. This review highlights the important structural, regulatory, functional, and unique features of the three major cytoskeletal protein groups in digestive epithelia. The emerging exciting biological aspects of these protein groups are their involvement in cell signaling via direct or indirect interaction with a growing list of associated proteins (MF, MT, IF), the identification of several disease-causing mutations (IF, MF), the functional role that they play in protection from environmental stresses (IF), and their functional integration via several linker proteins that bridge two or potentially all three of these groups together. The use of agents that target specific cytoskeletal elements as therapeutic modalities for digestive diseases offers potential unique areas of intervention that remain to be fully explored.
