RNA-seq in livers of wild-type (WT) controls, PiZ and PIZ mice deleted for Chop (PiZ/Chop-/-)

ABSTRACT: Transgenic PiZ mice have been genetically engineered to express ATZ and have been a valuable experimental model for liver disease due to AAT polymerization. ATZ accumulates in these mice within the endoplamic reticulum (ER) of hepatocytes in a nearly identical manner to livers of affected patients. To investigate the role of the transcription factor CHOP in the pathogenesis of liver damage induced by ATZ, we performed RNA-seq in livers of 6-week-old wild type, PiZ and PiZ mice deleted for Chop. All groups were matched for the strain, age, and the gender.

Liver miRNA profile of PiZ mice

Project description:Transgenic PiZ mice have been genetically engineered to express ATZ and have been a valuable experimental model for liver disease due to AAT polymerization. ATZ accumulates in these mice within the ER of hepatocytes in a nearly identical manner to livers of affected patients. MiRNAs play a key role in a wide range of biological processes and regulate gene expression mainly at the translational level. To search for miRNA with altered expression in AAT liver disease, we analyzed by miRNA next generation sequencing (NGS) the livers of 6-week-old PiZ mice and strain-, age-, and gender-matched wild-type mouse controls. This analysis revealed 70 miRNAs with differential expressions.

Gene expression analysis of PiZ mouse livers

Project description:Transgenic PiZ mice have been genetically engineered to express ATZ and have been a valuable experimental model for studing liver disease associated with AAT deficiency. ATZ accumulates in these mice within the ER of hepatocytes in a nearly identical manner to livers of affected patients. To investigate the pathogenesis of liver damage induced by ATZ, we performed gene expression analysis in livers of 6-week-old PiZ mice and strain-, age-, and gender-matched wild-type mouse controls. All samples were processed on Affymetrix Mouse 430A 2.0 arrays using GeneChip 3’-IVT Plus and Hybridization Wash and Stain kits by means of Affymetrix’s standard protocols. The analysis indicated that most genes upregulated in PiZ livers were associated with response to unfolded proteins, ER nuclear signaling pathway, and response to protein stimulus.

Gene Expression Levels in PiZ mice Compared to Wild-type (Wt)C57Bl/6

Project description:Individuals expressing alpha-1-antitrypsin mutant Z protein accumulate misfolded, mutant protein in the liver and are at risk for liver diseases including cirrhosis and hepatocellular carcinoma. Transgenic PiZ mice, a model for this liver disease, display similar pathologies to humans, including inflammation, increases in proliferation, autophagy and apoptosis, accumulation of globules and develop fibrosis and hepatocellular carcinoma with age. Microarrays were used to compare the gene expressions of PiZ mice to wild-type mice in order to identify the pathways that are altered in this disorder. Pooled samples from 4 mice, 3-4 months old were used for each of 4 categories. PiZ males, PiZ females, C57Bl/6 males, C57Bl/6 females

Calreticulin enhances the secretory trafficking of a polymerogenic alpha1-antitrypsin

Project description:α-1-antitrypsin (AAT) regulates protease activity in the lungs and liver. The presence of one or more copies of a mutant Z allele (AAT (E342K), called ATZ), results in low serum levels of ATZ along with intracellular inclusions of polymeric forms, causing lung emphysema and liver cirrhosis. Our experiments show that calreticulin (CRT), an endoplasmic reticulum (ER) glycoprotein chaperone, promotes the secretory trafficking of ATZ, enhancing the media to cell ratio. This effect is more specific for ATZ compared with AAT, and is only partially dependent on the glycan-binding site of CRT. The CRT-related chaperone calnexin (CNX) does not promote enhanced ATZ secretory trafficking, despite the higher cellular abundance of CNX-ATZ complexes. CRT deficiency alters the distributions of ATZ-ER chaperone complexes, increasing ATZ-BiP binding and inclusion body (IB) formation, and reducing ATZ interactions with components required for ER-Golgi trafficking. These findings indicate a novel role for CRT in promoting the secretory trafficking of a polymerogenic protein. Inefficient secretory trafficking of ATZ in the absence of CRT is coincident with enhanced accumulation of ER-derived ATZ IBs.

Differential gene expression in ATZ-globule-free and ATZ-globule-containing hepatocytes in PIZ mouse liver

Project description:Alpha-1-antitrypsin deficiency is a disease of the liver and lung where accumulation of misfolded ATZ protein forms large protein aggregates or globules that result in significant cellular stess. From Birth to 2 months of age, virtually every hepatocyte has numerous globules of the mutant ATZ protien. At 2 months of age small colonies of globule free hepatocytes arise and over time the liver becomes largely globule free. this analysis aims to identify differential gene expression profiles in the globule free vs the globule containing cells to idenitfy key factors and pathways regulating clearance of the mutant ATZ protien. We used Laser Capture Microdisection to isolate RNA from ATZ-globule-free hepatocytes and ATZ-globule-containing hepatocytes and subjected them to microarray analysis to detail the differential global gene expression profiles.
