Project description:We applied small RNA Solexa sequencing technology to identify microRNA expression in human liver samples from surgically removed liver tissues including three normal liver tissues (distal normal liver tissue of liver hemangioma), an hepatitis B virus (HBV)-infected liver, a severe chronic hepatitis B liver, two HBV-related hepatocellular carcinoma (HCC), an hepatitis C virus (HCV)-related HCC, and an HCC without HBV or HCV infection. All samples were collected with the informed consent of the patients and the experiments were approved by the ethics committee of Second Military Medical University, Shanghai, China. We investigated the miRNome in human normal liver and suggested some deregulated abundantly expressed microRNAs in HCC. center_name: National Key Laboratory of Medical Immunology & Institute of Immunology, Second Military Medical University, Shanghai, China.

Project description:We have performed a genome wide transcriptional survey of liver biopsies obtained from patients in Hunan China, who have chronic schistosomiasis with and without past viral hepatitis history, compared to patients with no liver disease history or indicators. These results present a comprehensive transcriptional profile of chronic schistosomiasis japonica patients and demonstrate similarities and differences with other hepatic diseases. These unique features of gene expression, in conjunction with previous reports of the cellular composition of granuloma formation and recovery, present an improved understanding of the molecular immunopathology and general physiological status underlying hepatic schistosomiasis. The gene expression profile of the human liver was examined for chronic patients with Schistosoma japonicum infections. Microarray analysis was performed on cRNA synthesised from total RNA derived from the liver biopsy tissue from huan China. Three groups were examined based on infections status [C] were without history or indicators of schistosomiasis or viral heapatitis controls ; [S] with a history or active for schistosomiasis but no indicators of viral heapatitis; and [S]
Project description:Chronic inflammation underpins many human diseases. The morbidity and mortality of chronic inflammation is often mediated through metabolic dysfunction. Inflammatory and metabolic processes vary through circadian time, suggesting an important temporal cross-talk between these systems. Here, we show that inflammatory arthritis results in rhythmic joint inflammation and drives major changes in muscle and liver energy metabolism and rhythmic gene expression.
Project description:Cone photoreceptor cell death in inherited retinal diseases, such as Retinitis Pigmentosa (RP), leads to the loss of accurate and color vision and ultimately blindness. In RP, a vast number of mutations are affecting the structure and function of rod photoreceptors while cones remain mutation-free. Once majority of rods have degenerated cones are dying secondarily due to the increased oxidative stress, inflammation and loss of structural and nutritional support normally provided by rods. Here we demonstrated that secondary cone cell death in animal models for RP is governed by an increased activity of histone deacetylates (HDACs). A single intravitreal injection of an HDAC inhibitor at a late stage of the disease, when majority of rods have already degenerated, is sufficient to delay cone death and support long-term cone survival. Surviving cones are retaining functionality and are mediating light-driven ganglion cell responses. RNA-seq analysis of surviving cones demonstrated that HDAC inhibition affords multi-level protection trough regulation of different prosurvival pathways including MAPK, PI3K-AKT and autophagy. These study suggest a unique possibility for targeted pharmacological protection of both primary degenerating rods and mutation-free secondary dying cones and creates hope to maintain vision in RP patients independent of the disease stage.
Project description:Tertiary lymphoid tissues (TLTs) are formed in systemic organs manifesting chronic inflammation. Herein, we found that the renal pelvis (RP) could form urinary tract-associated lymphoid tissues (UTALTs) in a TLT-formation manner in humans and mice with chronic kidney disease (CKD), regardless of infectious pyelonephritis. Our results demonstrated that urine is crucial for UTALT development. Urine leak from the lumen into the parenchyma of the RP through an altered transitional epithelium (TE) barrier, stimulated RP stromal cells immunologically and attracted immune cells via cytokine and chemokine production. Pathophysiological crosstalk was observed between UTALT development and tubulointerstitial lesions and TLT formation in the kidney.
Project description:Retinal degeneration is the leading cause of irreversible blindness. Retinitis pigmentosa (RP) is a genetically heterogenous group of diseases. In the United States, approximately one in 4000 individuals is affected. RP begins with the loss of night vision due to the loss of rod photoreceptor cells. The disease progresses slowly with the loss of peripheral vision, and eventually leads to complete debilitating and irreversible blindness. The first mutation associated with human RP was identified in the gene encoding rhodopsin, the G-protein coupled receptor of rod photoreceptor cells. Mutations within the rhodopsin gene account for significant portion of RP cases. Specifically, mutations of the proline at residue 347 in rhodopsin have been linked to human RP.
