Project description:Fumarylacetoacetate hydrolase (Fah), the last enzyme of the tyrosine degradation pathway, is specifically expressed in hepatocytes in the liver. Loss of Fah leads to liver failure in mice within 6-8 weeks. This can be prevented by blocking tyrosine degradation upstream of Fah with 2-(2-nitro-4-trifluoromethylbenzoyl)-1,3-cyclohexanedione (NTBC). Here, we investigate the impact of p21 on global gene expression in Fah deficiency. Experiment Overall Design: Livers from adult wildtype, Fah or Fah, p21 knockout mice were analyzed either after continuous treatment (ON) with NTBC or after NTBC withdrawal for 14 days (OFF).

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.

Project description:We collected whole genome testis expression data from hybrid zone mice. We integrated GWAS mapping of testis expression traits and low testis weight to gain insight into the genetic basis of hybrid male sterility.

Project description:Hereditary tyrosinemia type 1 (HT1) is a severe genetic disorder that affects the liver due to a defective fumarylacetoacetate hydrolase (Fah) enzyme in hepatocytes. The drug nitisinone (NTBC) has offered a life-saving treatment for HT1 patients by inhibiting the upstream enzyme 4-hydroxyphenylpyruvate dioxygenase (HPD). We used microarray analyses to define the impact of short-term (ie. seven days) NTBC therapy discontinuation on the gene expression profile of liver tissue of Fah-deficient mice. Consequently, we investigated the modulation of canonical pathways related to oxidative stress, glutathione metabolism and liver regeneration.

Project description:Reprogramming metabolism plays an important role in tumor cells for maintaining their abnormal biologic behaviors. Therefore, special factors could regulate metabolic processes and influence the overall status of tumor cells. This phenomenon was obviously found in melanoma. Fumarylacetoacetate hydrolase (fumarylacetoacetase, FAH) is an enzyme encoded by the FAH gene located on the chromosome 15q25.1 region and contains 14 exons. FAH enzyme catalyzes the hydrolysis of 4- fumarylacetoacetase into fumarate and acetoacetate. It is the last enzyme in the subpathway from L-phenylalanine and tyrosine degradation. Mutations in the FAH gene cause type I tyrosinemia, which is a hereditary error of metabolism that is characterized by increased tyrosine levels in the blood and urine of patients. In the present study, we will explore whether FAH is an essential enzyme to promote multiple metabolic processes and elucidate the functions of FAH in melanoma. Gene microarrays and bioinformatics analysis of the differentially expressed genes (DEGs) were performed using A375 cells, and we concentrated on the biologic functions of FAH. In general, our work revealed several functional mechanisms of FAH in melanoma, which indicated FAH might be a potentially therapeutic target and an independent prognostic indicator for this disease.
