Non-alcoholic fatty liver disease(NAFLD)is a widely prevalent hepatic disorder that covers wide spectrum of liver pathology.NAFLD is strongly associated with liver inflammation,metabolic hyperlipidaemia and insulin resistance.Frequently,NAFLD has been considered as the hepatic manifestation of metabolic syndrome.The pathophysiology of NAFLD has not been fully elucidated.Some patients can remain in the stage of simple steatosis,which generally is a benign condition;whereas others can develop liver inflammation and progress into non-alcoholic steatohepatitis,fibrosis,cirrhosis and hepatocellular carcinoma.The mechanism behind the progression is still not fully understood.Much ongoing proteomic researches have focused on discovering the unbiased circulating biochemical markers to allow early detection and treatment of NAFLD.Comprehensive genomic studies have also begun to provide new insights into the gene polymorphism to understand patientdisease variations.Therefore,NAFLD is considered a complex and mutifactorial disease phenotype resulting from environmental exposures acting on a susceptible polygenic background.This paper reviewed the current status of proteomic and genomic studies that have contributed to the understanding of NAFLD pathogenesis.For proteomics section,this review highlighted functional proteins that involved in:(1)transportation;(2)metabolic pathway;(3)acute phase reaction;(4)antiinflammatory;(5)extracellular matrix;and(6)immune system.In the genomic studies,this review will discuss genes which involved in:(1)lipolysis;(2)adipokines;and(3)cytokines production. 展开更多

Objective\ To understand the transcription of BamHI L DNA fragment from genome of strong virulent GA strain of Marek′s disease herpesvirus (MDV) in lymphoblastoid tumor tissue induced by oncogenic strain Beijing 1 (a specific local strain in China) of MDV. Methods\ Two oligonucleotide primers were synthesized according to the reported sequence of \%meq\% gene an ideal oncogenic candidate and our previously determined sequence of BamHI L fragment of Marek′s disease herpesvirus (MDV), respectively. Reverse transcriptase PCR(RT PCR) assay was performed by using these primers and the mRNA as a template which was isolated from visceral lymphoblastoid tumors obtained from chickens artificially infected with strain Beijing 1 of oncogenic MDV. Southern blot molecular hybridization was further carried out to detect the product of RT PCR with digoxigenin labeled nucleotide probe from BamHI I2 and L fragment in the gene library of MDV strain GA, respectively. Results\ Two probes could simultaneously hybridize this cDNA amplified by RT PCR with a length of about 730 bp. Conclusion\ It is suggested that \%meq\% transcription could extend from the right hand end of BamHI I2 to the adjacent BamHI L, and the BamHI L region was likely to be transcribed in MDV induced lymphoblastoid tumors. 展开更多
