Project description:Clonorchiasis remains an important zoonotic parasitic disease worldwide. The molecular mechanisms of host-parasite interaction are not fully understood. Non-coding microRNAs (miRNAs) are considered to be key regulators in parasitic diseases. The regulation of miRNAs and host micro-environment may be involved in clonorchiasis, and require further investigation. MiRNA microarray technology and bioinformatic analysis were used to investigate the regulatory mechanisms of host miRNA and to compare miRNA expression profiles in the liver tissues of Clonorchis sinensis-infected rats and controls.A total of eight miRNAs were downregulated and two were upregulated, which showed differentially altered expression profiles in the liver tissue of C. sinensis-infected rats. Further analysis of the differentially expressed miRNAs revealed that many important signal pathways were triggered after infection with C. sinensis, which were related to clonorchiasis pathogenesis, such as cell apoptosis and inflammation, as well as genes involved in signal transduction mechanisms, such as pathways in cancer and the Wnt and Mitogen-activated protein kinases (MAPK) signaling pathways.This dysregulation in miRNA expression may contribute to the etiology and pathophysiology of clonorchiasis. These results also provide new insights into the regulatory mechanisms of miRNAs in clonorchiasis, which may present potential targets for future C. sinensis control strategies.

Project description:Clonorchiasis is associated with bile duct malignancy and the subsequent development of cholangiocarcinoma. Although this is likely caused by adult Clonorchis sinensis and its excretory-secretory products (ESP), the precise molecular mechanisms remain obscure. To evaluate the effect of C. sinensis infection on differential gene expression in host hepatocytes, we used cDNA microarrays in human cholangiocarcinoma cells through the mimicking of C. sinensis infestation, and analyzed differential mRNA expression patterns of host cells.

Project description:Clonorchis sinensis is a zoonotic parasite causing clonorchiasis associated with human diseases such as biliary calculi, cholecystitis, liver cirrhosis, and is classified as carcinogenic to humans for cholangiocarcinoma. MicroRNAs (miRNAs) are non-coding, regulating small RNA molecules essential for the complex life cycle of parasites and involved in parasitic infections. To identify and characterize miRNAs expressed in adult C. sinensis residing chronically in the biliary tract, we developed an integrative approach combining deep sequencing, bioinformatic predictions with stem-loop real-time PCR analysis. Here we report the use of this approach to identify and clone 6 new and 62,512 conserved C. sinensis miRNAs which belong to 284 families. There is strong bias on families, family members and sequence nucleotides in C. sinensis. Uracil is the dominant nucleotide, particularly at positions 1, 14 and 22, which were located approximately at the beginning, middle and the end of conserved miRNAs. There is no significant M-bM-^@M-^\seed regionM-bM-^@M-^] at the first and ninth positions commonly found in human, animals and plants. Categorization of conserved miRNAs indicated that miRNAs of C. sinensis are still innovated and concentrated along three branches of the phylogenetic tree leading to bilaterians, insects and coelomates. There are two miRNA strategies in C. sinensis for its parasitic life: keeping a large category of miRNA families of different animals and keeping a stringent conserved seed region with high active innovation in other place of miRNA mainly in the middle and the end, which are perfect for the parasite to perform its complex life style and for host changes. The present study represents the first large scale characterization of C. sinensis miRNAs, which have implications for understanding the complex biology of this zoonotic parasite, as well as the miRNA studies of other related species such as Opisthorchis felineus and O. viverrini of human and animal health significance.

Project description:Clonorchiasis is a foodborne zoonotic disease caused by Clonorchis sinensis which belongs to trematodes with a complex lifecycle, there are increasing evidences that small RNAs including microRNAs and PIWI-interacting RNAs can participate in regulation of embryonic development. However, there is little information about the small RNAs in the different developmental stages of C. sinensis. In the present study, we investigated profiles of miRNAs and piRNAs in the different developmental stages including eggs, metacercaria and adults of C. sinensis using high-throughout sequencing technology. We found that 152 miRNAs for adults, 147 miRNAs for metacercariae and 161 miRNAs for eggs were identified, of these miRNAs, 52 miRNAs were universally expressed in these three developmental stage. For piRNAs, we also found that there were a total of 4573 piRNAs in adult worms, 3189 piRNAs in eggs and 3853 piRNAs in metacercariae, respectively, and 1127, 426, 756 piRNAs were absolutely expressed only in adults, eggs and metacercariae, respectively. These stage-specific small RNAs might be involved in various biological process and environmental adaption for parasitism as showed by GO and KEGG pathway analysis. The data of present study may provide a basis for future targeting at these stage-specific small RNAs for prevention and control clonorchisias.

Project description:Background: Liver cancer is the third deadliest type of cancer, posing a serious threat to human health. Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer. C. sinensis, classified as a definite group I carcinogen by the IARC (International Agency for Research on Cancer), is an important risk factor for HCC. Although many studies have shown that C. sinensis infection affects the prognosis of HCC patients, the specific mechanisms are still unclear, especially the dynamics and regulatory roles of chromatin accessibility. Results: In this study, we integrated ATAC-seq, RNA-seq, and ChIP-seq data to elucidate changes in the epigenetics of HCC after the C. sinensis infection. Many different accessibility regions (DARs) were identified both in tumors and adjacent tissue after the C. sinensis infection. Meanwhile, top TFs whose motifs were enriched in DAR were found, such as HNF4a, FOXI1, etc. Although there were slight deviations, epigenetic changes were found to be consistent with gene expression levels. We also revealed that H3K9ac, H3K4me2, H3K4me3, H3K27ac, and H3K4me1 were associated with chromatin accessibility. Importantly, we also found potential evidence that C. sinensis infection would alter the spatial structure of the HCC genome. Finally, both molecular experimental results and clinical data certified that C. sinensis infection would promote the metastasis of HCC. Conclusions: C. sinensis infection will remodel the chromatin accessibility of HCC, leading to changes in gene expression levels. This study provides conclusive evidence that C. sinensis infection alters the epigenetics of HCC.

Project description:<p><strong>BACKGROUND:</strong> Clonorchiasis, an infectious disease caused by the liver fluke <em>Clonorchis sinensis</em>, may lead to the development of liver and gallbladder diseases, and even cholangiocarcinoma (CCA). However, the pathogenesis, host-pathogen interaction, and diagnostic markers for clonorchiasis remain unclear.</p><p><strong>METHODS:</strong> Eighteen rabbits were randomly divided into control group (n = 9) and <em>C. sinensis</em>-infected group (n = 9), and their plasma samples were collected at 7, 14, 28 and 63 days post-infection (dpi). Biochemical indices and metabolites in different infection periods were detected. A non-targeted ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) approach was employed to investigate the metabolic profiles of plasma in rabbits, and related metabolic pathways of differential metabolites and correlation between candidate biochemical indices and differential metabolites were analyzed. Finally, the candidate biomarkers were verified with human samples using a targeted metabolomics method.</p><p><strong>RESULTS:</strong> The result of biochemical indices indicated <em>C. sinensis</em> infection would affect the liver function biochemical indices, especially alanine aminotransferase, aspartate transaminase (AST), glutamyl transpeptidase (GGT), total bile acid, high-density lipoprotein and cholinesterase. The metabonomic results showed that 58, 212, 23 and 21 differential metabolites were identified in different phases of the infection. Multivariate statistical analysis of differential metabolites revealed distinct metabolic signatures during different phases of infection, with most of these signatures being observed at 14 dpi, which mainly influences the amino acid metabolisms. For metabolites and biochemical indices, AST, GGT, hypoxanthine, l-pipecolic acid and d-glucuronate represented potential noninvasive biomarkers for the diagnosis of <em>C. sinensis</em> (P < 0.05 and AUC > 0.8). Furthermore, GGT and d-glucuronate levels were positively correlated with the infection (r(28) = 0.98, P < 0.0001) and showed excellent diagnostic performance (AUC = 0.972; 95% confidence interval, 0.921 to 1.000).</p><p><strong>CONCLUSIONS:</strong> The present results provide new insights into plasma metabolic changes in rabbits during <em>C. sinensis</em> infection, and the potential biomarker may be used for developing an effective method to diagnose clonorchiasis in the future.</p>

Project description:Developmental gene expression patterns (9812 genes) of juvenile and adult C. sinensis were analyzed using a 12K oligonucleotide microarray (a total of 11617 genes). A number of significantly differentially expressed genes having more than 2-fold difference were observed in adult stage compared to juvenile stage. This finding suggests that the expression levels of different gene sets are controlled in C. sinensis for adaptation to environmental change, such as developmental stages.
