Single Amino Acid Polymorphisms in the Fasciola hepatica Carboxylesterase Type B Gene and Their Potential Role in Anthelmintic Resistance. Pathogens 2023; 12:1255. [PMID: 37887771 PMCID: PMC10610349 DOI: 10.3390/pathogens12101255] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2023] [Revised: 10/13/2023] [Accepted: 10/16/2023] [Indexed: 10/28/2023] Open
Abstract
The expression of the Fasciola hepatica carboxylesterase type B (CestB) gene is known to be induced upon exposure to the anthelmintic triclabendazole (TCBZ), leading to a substantial rise in enzyme-specific activity. Furthermore, the nucleotide sequence of the CestB gene displays variations that can potentially result in radical amino acid substitutions at the ligand binding site. These substitutions hold the potential to impact both the ligand-protein interaction and the catalytic properties of the enzyme. Thus, the objective of our study was to identify novel CestB polymorphisms in TCBZ-resistant parasites and field isolates obtained from a highly endemic region in Central Mexico. Additionally, we aimed to assess these amino acid polymorphisms using 3D modeling against the metabolically oxidized form of the anthelmintic TCBZSOX. Our goal was to observe the formation of TCBZSOX-specific binding pockets that might provide insights into the role of CestB in the mechanism of anthelmintic resistance. We identified polymorphisms in TCBZ-resistant parasites that exhibited three radical amino acid substitutions at positions 147, 215, and 263. These substitutions resulted in the formation of a TCBZSOX-affinity pocket with the potential to bind the anthelmintic drug. Furthermore, our 3D modeling analysis revealed that these amino acid substitutions also influenced the configuration of the CestB catalytic site, leading to alterations in the enzyme's interaction with chromogenic carboxylic ester substrates and potentially affecting its catalytic properties. However, it is important to note that the TCBZSOX-binding pocket, while significant for drug binding, was located separate from the enzyme's catalytic site, rendering enzymatic hydrolysis of TCBZSOX impossible. Nonetheless, the observed increased affinity for the anthelmintic may provide an explanation for a drug sequestration type of anthelmintic resistance. These findings lay the groundwork for the future development of a molecular diagnostic tool to identify anthelmintic resistance in F. hepatica.

Transcriptome-Based Identification of a Functional Fasciola hepatica Carboxylesterase B. Pathogens 2021; 10:pathogens10111454. [PMID: 34832612 PMCID: PMC8623527 DOI: 10.3390/pathogens10111454] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2021] [Revised: 10/30/2021] [Accepted: 11/05/2021] [Indexed: 11/16/2022] Open
Abstract
Bioinformatics analysis of the complete transcriptome of Fasciola hepatica, identified a total of ten putative carboxylesterase transcripts, including a 3146 bp mRNA transcript coding a 2205 bp open reading frame that translates into a protein of 735 amino acids, resulting in a predicted protein mass of 83.5 kDa and a putative carboxylesterase B enzyme. The gene coding for this enzyme was found in two reported F. hepatica complete genomes stretching 23,230 bp, containing two exons of 1282 and 1864 bp, respectively, as well as a 20,084 bp intron between the exons. The enzymatic activity was experimentally assayed on F. hepatica protein extracts by SDS-PAGE zymograms using synthetic chromogenic substrates, confirming both the theoretical molecular weight and carboxylesterase enzymatic activity. Further bioinformatics predicted that this enzyme is an integral component of the cellular membrane that should be active as a 167 kDa homodimer complex and polyacrylamide gel electrophoresis (PAGE) zymograms experiments confirmed the analysis. Additional bioinformatics analysis showed that DNA sequences that code for this particular enzyme are highly conserved in other parasitic trematodes, although they are labeled hypothetical proteins.

Abstract
Fine tuning of the metabolic, physiological and immunological cues along with interplay between the biomolecules of the host and the parasite could be responsible for the successful establishment of parasitic infections. The present investigation was aimed at evaluating the oxidative status and the level of adenosine deaminase (ADA) in the serum and liver of rabbits experimentally infected with Fasciola gigantica. A significant increase in level of ROS, MDA and 4-HNE along with a decline in the SOD, CAT, GR and GST activity was evident in rabbits experimentally infected with Fasciola gigantica. However, there was an increase in the GPX activity in the sera of infected rabbits. The increased GPX activity and decreased GR activity would have resulted in the depletion of GSH, a key non-enzymatic antioxidant, in the infected animals. The level of GSSG was also found to be higher in the sera and liver tissues of the infected rabbits along with a decline in the GSH/GSSG ratio, indicating a high level of oxidative stress in the infected animals, which also showed a significant increase in the activity of the marker enzymes of liver pathology, AST and ALT. Further, a significant inhibition of the adenosine deaminase (ADA) activity in the infected rabbits was accompanied with the reduction in the level of pro-inflammatory cytokine, IL-6 while the anti-inflammatory cytokine, IL-4 level was significantly elevated. In conclusion, the F. gigantica induced significant oxidative stress as evident from the increased levels of ROS and lipid peroxidation along with the disruption of antioxidant and detoxification cascade ultimately lead to pathogenic and inflammatory responses in the experimental host. Whereas, the altered ADA activity could modulate the host's immune responses toward Th-2 type and would facilitate the successful establishment of flukes within their host, thus indicating that ADA could be exploited as a target for the development of novel anthelmintic drugs against fasciolosis.

Abstract
Cystic hydatid disease (CHD) is a worldwide neglected zoonotic disease caused by Echinococcus granulosus. The parasite is well adapted to its host by producing protective molecules that modulate host immune response. An unexplored issue associated with the parasite's persistence in its host is how the organism can survive the oxidative stress resulting from parasite endogenous metabolism and host defenses. Here, we used hydrogen peroxide (H2O2) to induce oxidative stress in E. granulosus protoescoleces (PSCs) to identify molecular pathways and antioxidant responses during H2O2 exposure. Using proteomics, we identified 550 unique proteins; including 474 in H2O2-exposed PSCs (H-PSCs) samples and 515 in non-exposed PSCs (C-PSCs) samples. Larger amounts of antioxidant proteins, including GSTs and novel carbonyl detoxifying enzymes, such as aldo-keto reductase and carbonyl reductase, were detected after H2O2 exposure. Increased concentrations of caspase-3 and cathepsin-D proteases and components of the 26S proteasome were also detected in H-PSCs. Reduction of lamin-B and other caspase-substrate, such as filamin, in H-PSCs suggested that molecular events related to early apoptosis were also induced. We present data that describe proteins expressed in response to oxidative stress in a metazoan parasite, including novel antioxidant enzymes and targets with potential application to treatment and prevention of CHD.

Understanding the main route of drug entry in adult Fasciola hepatica: Further insights into closantel pharmacological activity. Exp Parasitol 2017; 181:23-29. [PMID: 28734749 DOI: 10.1016/j.exppara.2017.07.003] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2017] [Revised: 06/28/2017] [Accepted: 07/17/2017] [Indexed: 11/18/2022]
Abstract
Closantel (CLS) is highly effective against adult liver flukes after its oral or subcutaneous (sc) administration in ruminants. Trans-tegumental diffusion and oral ingestion are the two potential routes available for the entry of drugs into Fasciola hepatica. The work reported here contributes to improve the understanding of CLS pharmacology. The main goals of were: I) to determine the pattern of in vivo CLS accumulation into adult F. hepatica and relevant tissues in CLS-treated sheep; II) to investigate the influence of the physicochemical composition of the incubation medium on the CLS diffusion process into adult F. hepatica; III) to assess the ovicidal activity of CLS against F. hepatica eggs; and IV) to investigate the in vivo effect of CLS treatment on glutathione S-transferases activity in adult liver flukes exposed to CLS. Fourteen healthy sheep were each orally infected with 75 F. hepatica metacercariae. Sixteen (16) weeks after infection, animals were treated with CLS by oral (n = 6, 10 mg/kg) or sub-cutaneous (sc) (n = 6, 5 mg/kg) route. At 12, 24 and 36 h post-treatment, animals were sacrificed (n = 2) and samples of blood, bile and adult F. hepatica were collected. In addition, flukes recovered from non-treated sheep (n = 2) were ex vivo incubated (60 min) in the presence of CLS in either RPMI or bile as incubation medium. CLS concentration was measured by HPLC. The ovicidal activity of CLS was investigated using eggs obtained from the bile of untreated sheep. Finally, glutathione S-transferase activity in F. hepatica recovered from untreated and CLS-treated sheep was assessed. In the in vivo studies, the highest CLS concentrations were measured in plasma and adult liver flukes. A positive correlation was observed between CLS concentration in plasma and in F. hepatica. Results obtained in the current work indicate that the in vivo accumulation of CLS into adult liver flukes occurs mainly by the oral route. After ex vivo incubation, the uptake of CLS by the parasite was markedly diminished in the presence of bile compared with that observed in the presence of RPMI as incubation medium. CLS lacks ovicidal activity at therapeutically relevant concentrations. Lastly, CLS significantly increased glutathione S-transferase activity in flukes recovered at 12 h (oral treatment) and 24 h (sc treatment), compared to the control liver flukes.

Abstract
The aim of this study was to evaluate hepatic and seric levels of purines, as well as their breakdown products in rats infected by Fasciola hepatica on days 15 and 87 post-infection (PI). Rats were divided into two groups: uninfected (n = 10) and infected (n = 20). On day 15 (n = 5 for uninfected group and n = 10 for infected group) and 87 PI (n = 5 for uninfected group and n = 10 for infected group), animals were euthanized for sampling to evaluate levels of purines by high-performance liquid chromatography. In serum, ATP increased (P < 0.05) and ADP decreased (P < 0.05) on days 15 and 87 PI, while AMP increased (P < 0.05) only on day 15 PI. Hypoxanthine levels increased (P < 0.05) on days 15 and 87 PI, while adenosine and xanthine levels decreased and increased (P < 0.05), respectively, on day 87 PI. No difference was observed regarding seric inosine and uric acid (P > 0.05). Hepatic ATP, adenosine, and uric acid levels decreased (P < 0.05) on days 15 and 87 PI. AMP levels decreased (P < 0.05) on day 87 PI, while xanthine levels increased (P < 0.05) on day 15 PI in the liver. Also in the liver, hypoxanthine levels increased (P < 0.05) on day 15 PI and decreased (P < 0.05) on day 87 PI. On the other hand, there was no difference on hepatic ADP and inosine levels (P > 0.05). Therefore, it is possible to conclude that F. hepatica infection can change purine levels, which may be associated with an inflammatory process, and these alterations may influence fasciolosis pathogenesis.

Abstract
Xenobiotic-metabolizing enzymes (XMEs) modulate the biological activity and behavior of many drugs, including anthelmintics. The effects of anthelmintics can often be abolished by XMEs when the drugs are metabolized to an inefficient compound. XMEs therefore play a significant role in anthelmintic efficacy. Moreover, differences in XMEs between helminths are reflected by differences in anthelmintic metabolism between target species. Taking advantage of the newly sequenced genomes of many helminth species, progress in this field has been remarkable. The present review collects up to date information regarding the most important XMEs (phase I and phase II biotransformation enzymes; efflux transporters) in helminths. The participation of these XMEs in anthelmintic metabolism and their possible roles in drug resistance are evaluated.
