Project description:We used a mouse model of alveolar echinococcosis to assess gene expression profiles in the liver after establishment of a chronic disease status as a result of a primary peroral infection with eggs of the fox tapeworm Echinococcus multilocularis.
Project description:Hepatic echinococcosis (HE) caused by Echinococcus spp. transmitted from carnivores is known as a severe zoonotic disease that formed into hepatic cystic echinococcosis (HCE) and hepatic alveolar echinococcosis (HAE). It continues to be a serious public health issue around the world. HAE is uncommon infection which is characterized by poor prognosis but it is the most life-threatening compare to HCE. Many cases of HAE are recognized at forward stages because clinical symptoms may remain silent in about 10 years of incubation period. Several pathological cases could be observed including septicemia, abscess, recurrent cholangitis, and portal hypertensive gastrointestinal bleeding in untreated people. It is provided that correlated factors includes CD44, Soluble ST2 (sST2), Plasma IL-23, IL-27, and IL-5 for metastasis and prognosis for patients with HAE were identified. However, data on metastatic and prognostic marker are still so poor. Recent studies have revealed that circRNAs are enriched and stable in exosomes. Exosomal circRNAs may be localized in platelet-derived extracellular vesicles, hepatic cells, and pancreatic cancer cells. Studies have suggested that it is possible that cells may transfer circRNAs by excreting them in exosomes. Whereas there are a lot of studies on cancer and other human diseases related exosomal circRNA, no studies on hepatic alveolar echinococcosis-related exosomal circRNAs in humans. Current study provides that exosomal circular RNAs from healthy humans and humans with hepatic alveolar echinococcal disease were detected and characterized using the RNA sequencing.

Project description:For Samples GSM601017-28: The aim of this study was to use expression profiling to define transcriptional patterns and regulatory pathways that characterize the host liver response to E. multilocularis infection in the experimental model of secondary infection, to compare gene expression in this model to those described in the model of "primary infection", and to follow the changes in gene expression and in the expression of a cell proliferation marker over time during the complete chronic phase of E.multilocularis infection, following early and middle stages. For Samples GSM601029-40: The aim of this study was to use expression profiling to define transcriptional patterns and regulatory pathways that characterize the host liver response to E. multilocularis infection in the experimental model of secondary infection, to compare gene expression in this model to those described in the model of "primary infection", and to follow the changes in gene expression and in the expression of a cell proliferation marker over time during the complete chronic phase of E.multilocularis infection, following its middle and late stages. For Samples GSM601017-28: The anterior liver tissue sample of control mice group and alveolar echinococcosis mice group were obtained at each time point(1 month and 3 month). Biological replicates is 3. Then, total RNA from anterior liver of both groups were used as test sample, which labelled cy5 fluorescein, and the pool RNA of healthy BALB/c mice anterior liver was used as reference sample, which labelled cy3 fluorescein, and then hybridized to 32K Mouse Genome Array Genechips, representing about 25000 characterized murine genes. For Samples GSM601029-40: The anterior liver tissue sample of control mice group and alveolar echinococcosis mice group were obtained at each time point(2 month and 6 month). Biological replicates is 3. Then, total RNA from anterior liver of both groups were used as test sample, which labelled cy5 fluorescein, and the pool RNA of healthy BALB/c mice anterior liver was used as reference sample, which labelled cy3 fluorescein, and then hybridized to 36K Mouse Genome Array Genechips, representing about 25000 characterized murine genes.
Project description:RATIONALE: Studying the genes expressed in samples of tissue from patients with cancer may help doctors identify biomarkers related to cancer.
PURPOSE: This laboratory study is using gene expression profiling to evaluate normal tissue and tumor tissue from patients with colon cancer that has spread to the liver, lungs, or peritoneum.
