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.

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.

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.

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 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.

Project description:Introgressed variants from other species can be an important source of genetic variation because they may arise rapidly, can include multiple mutations on a single haplotype, and have often been pretested by selection in the species of origin. Although introgressed alleles are generally deleterious, several studies have reported introgression as the source of adaptive alleles-including the rodenticide-resistant variant of Vkorc1 that introgressed from Mus spretus into European populations of Mus musculus domesticus. Here, we conducted bidirectional genome scans to characterize introgressed regions into one wild population of M. spretus from Spain and three wild populations of M. m. domesticus from France, Germany, and Iran. Despite the fact that these species show considerable intrinsic postzygotic reproductive isolation, introgression was observed in all individuals, including in the M. musculus reference genome (GRCm38). Mus spretus individuals had a greater proportion of introgression compared with M. m. domesticus, and within M. m. domesticus, the proportion of introgression decreased with geographic distance from the area of sympatry. Introgression was observed on all autosomes for both species, but not on the X-chromosome in M. m. domesticus, consistent with known X-linked hybrid sterility and inviability genes that have been mapped to the M. spretus X-chromosome. Tract lengths were generally short with a few outliers of up to 2.7 Mb. Interestingly, the longest introgressed tracts were in olfactory receptor regions, and introgressed tracts were significantly enriched for olfactory receptor genes in both species, suggesting that introgression may be a source of functional novelty even between species with high barriers to gene flow.
