Project description:We present the first study to confirm the existence of DNA methylation in the parasitic nematode Trichinella spiralis, and we characterize the methylomes of the three life-cycle stages of this food-borne infectious human pathogen. We observe a drastic increase in DNA methylation during the transition from the new born to mature stage, and we further identify parasitism-related genes that show changes in DNA methylation status between life cycle stages. We also evaluated differential gene expression among the three life stages using Illumina HiSeq 2000 RNA-seq technology.

Project description:Trichinella spiralis is a highly destructive parasitic nematode that invades and destroys intestinal epithelial cells, injures many different tissues during its migratory phase, and occupies and transforms myotubes during the final phase of its life cycle. Mice deficient in the IL-1 family receptor for the DAMP, IL-33 (called ST2), display reduced intestinal Th2 responses and impaired mast cell activation. IL-33 was constitutively expressed in intestinal epithelial cells, where it became concentrated in nuclei within 2 days of infection. Nuclear localization was an innate response to infection that occurred in intestinal regions where worms were actively migrating. We isolated intestinal epithelial cells from uninfected mice (cytoplasmic IL-33) and mice at 2 days post-infection (nuclear IL-33) to compare global expression profiles. We used microarrays to characterize the global gene expression that occurs in intestinal epithelial cells following T. spiralis-induced nuclear translocation of IL-33.

Project description:Trichinellosis of human and other mammals was caused through the ingestion of the parasite，Trichinella spiralis，contaminated meat. It is a typical zoonotic disease that affects more than 10 million people world-wide. Parasites of Trichinella genus are unique intracellular pathogens. Adult Trichinella parasites directly release newborn larvae which invade striated muscle cells and causes diseases. In this study, we profiled the global transcriptome in the three developmental stages of T. spiralis. The transcriptomic analysis revealed the global gene expression patterns from newborn larval stage through muscle larval stage to adults. Thousands of genes with stage-specific transcriptional patterns were described and novel genes involving host-parasite interaction were identified. More than 45% of the protein-coding genes showed evidence of transcription from both sense and antisense strands which suggests the importance of RNA-mediated gene regulation in the parasite. This study presents a first deep analysis of the transcriptome of T. spiralis, providing insight information of the parasite biology.

Project description:The excretory-secretory proteins (ESPs) of Trichinella spiralis (T. spiralis) muscle larvae have been confirmed to exert antitumor effects by modulating host immune responses or directly acting on tumor cells. Our research group previously identified that the ESPs of T. spiralis muscle larvae contain multiple proteins potentially related to antitumor activity, among which tropomyosin (TM) has attracted our attention. This study aims to introduce TM from Trichinella spiralis (T. spiralis TM) into breast cancer MCF-7 cells via transfection technology. Furthermore, we investigated the impact of T. spiralis TM on the gene expression profile of MCF-7 cells through transcriptomics. Finally, the study systematically evaluated its regulatory effects on apoptosis, proliferation, and migration. We are the first to comprehensively evaluated the anticancer effects of T. spiralis TM on MCF-7 breast cancer cells. Our findings showed that T. spiralis TM increases apoptosis by activating the mitochondrial-mediated apoptosis pathway and inhibits cell migration and proliferation by downregulating the expression of important hub genes, including PRKACA, CDK3, VPS35, and BCAR1. These findings provide a novel theoretical basis for the application of molecules linked to Trichinella in tumor therapy and support for potential new targets.

Messenger RNA from three developmental stages of T. spiralis was selectively purified from total RNA using oligo-(dT) conjugated magnetic beads. Complementary DNA (cDNA) was synthesized guided by oligo-(dT) as a primer.
