Project description:Scientific evidence suggests that not only murine scent communication is regulated by major urinary proteins, but that their expression may also vary in response to metabolism via a yet unknown mechanism. Major urinary proteins are expressed mainly in the liver, showing a sexually dimorphic pattern with substantially higher expression in males. Here, we investigate the metabolic implications of a major urinary protein knockout in twelve-week-old male and female C57BL/6N mice during ad libitum feeding. Despite both sexes of major urinary protein knockout mice displayed numerically increased body weight and visceral adipose tissue proportions compared to sex-matched wildtype mice, the main genotype-specific metabolic differences were observed exclusively in males. Male major urinary protein knockout mice exhibited plasma and hepatic lipid accumulation accompanied by a hepatic transcriptome indicating an activation of lipogenesis. These findings match the higher major urinary protein expression in male compared to female wildtype mice, suggesting a more distinct reduction in energy requirements in male compared to female major urinary protein knockout mice. The observed sex-specific anabolic phenotype confirms a role of major urinary protein in metabolism and, since major urinary proteins are not expressed in humans, suggests the major urinary protein knockout mouse as a potential alternative model for translational metabolism research which needs to be further elucidated.

Project description:Male house mice were housed under semi-natural conditions and their urinary proteins were quantified using MS1 and MS2 based label-free strategies. This dataset consists of 52 raw MS files, comprising 26 DIA (SWATH) and 26 IDA runs on a TripleTOF 5600. The composition of the dataset is described in the manuscript by Enk et al., titled: "Regulation of highly homologous Major Urinary Proteins in house mice quantified with label-free proteomic methods ", Molecular Biosystems, in review.

Project description:Major urinary proteins (MUP) are the major component of the urinary protein fraction in house mice (Mus spp.) and rats (Rattus spp.). The structure, polymorphism and functions of these lipocalins have been well described in the western European house mouse (Mus musculus domesticus), clarifying their role in semiochemical communication. The complexity of these roles in the mouse raises the question of similar functions in other rodents, including the Norway rat, Rattus norvegicus. Norway rats express MUPs in urine but information about specific MUP isoform sequences and functions is limited. In this study, we present a detailed molecular characterization of the MUP proteoforms expressed in the urine of two laboratory strains, Wistar Han and Brown Norway, and wild caught animals, using a combination of manual gene annotation, intact protein mass spectrometry and bottom-up mass spectrometry-based proteomic approaches. Detailed sequencing of the urinary MUP isoforms reveals a less complex pattern of primary sequence polymorphism in the rat than the mouse. However, rat MUPs exhibit added complexity in the form of post-translational modifications, including the phosphorylation of Ser4 in some isoforms, and exoproteolytic trimming of specific isoforms.

Project description:Hepatocyte nuclear factor-1β (HNF-1β) is an essential transcription factor that regulates tissue-specific gene expression in the kidney, liver, pancreas and genitourinary tract. In humans, mutations of HNF-1β cause renal cysts and diabetes (RCAD) and congenital anomalies of the kidney and urinary tract (CAKUT). Inactivation of Hnf-1β in tubular epithelial cells throughout the nephron leads to early-onset cyst formation and postnatal lethality. Here, we used Pkhd1/Cre mice to delete Hnf-1β specifically in renal collecting ducts (CD). Hnf-1β mutant mice survived long-term and developed slowly progressive cystic kidney disease, renal fibrosis, and hydronephrosis. Compared with wild-type littermates, Hnf-1β mutant mice had higher urine volume, lower urine osmolality, and higher water intake. Differences were seen at baseline, following 24h water restriction, and following administration of dDAVP. Circulating ADH levels were similar in wild type and mutant mice. Polyuria, polydipsia, and decreased urine osmolality were present prior to the onset of cyst formation and hydronephrosis. These findings indicated that Hnf-1β mutant mice have a primary defect in urinary concentrating ability. Studies using in vitro hypertonicity response experiments identified NR1H4 (FXR), a transcription factor previously shown to regulate water homeostasis, as a novel HNF-1β target. mIMCD3 cells exposed to hypertonic medium robustly upregulated Fxr mRNA levels; this upregulation was lost in Hnf-1β mutant cells. HNF-1β was bound to the Fxr promoter region in vivo, and Fxr mRNA was significantly downregulated in mutant mice. FXR protein localized to CD in wild-type mice and was almost undetectable in the cyst epithelium of mutant mice. These findings highlight a new and critical role for HNF-1β in urinary concentration and hypertonicity by regulating the transcription of FXR in the CD.

Project description:Laboratory mice are standardly housed around 23ºC, setting them under chronic cold stress. Metabolic changes of liver in mice housed under thermoneutral, standard and cold temperatures remain unknown. Here we isolated lipid droplets and mitochondria from their livers for comparative proteomic study to investigate the changes. According to proteomic analysis, mitochondrial TCA cycle and retinol metabolism were enhanced while oxidative phosphorylation was no obviously affected under cold condition, suggesting liver mitochondria may increase TCA cycle capacity in biosynthetic pathways as well as retinol metabolism to help liver to adapt. Based on proteomic and immunoblotting results, Perilipin 5 and major urinary proteins were increased significantly while mitochondrial pyruvate carrier was decreased dramatically under cold condition, indicating a role they may play.

Project description:Nitric oxide (NO) is a crucial gaseous signaling molecule engaged in a variety of physiological and pathological processes. It is produced by three isoenzymes called nitric oxide synthases (NOS): neuronal, inducible and endothelial NOS (eNOS). eNOS-derived NO plays an important role in endothelium-dependent vasodilation as well as in lipid and glucose homeostasis in the liver. In addition, it has been shown that NO exert a beneficial effect on mitochondrial biogenesis and respiration. Thus, the aim of our study was to used iTRAQ-based quantitative proteomics to investigate the changes in protein expression in the mitochondrial and cytosolic fractions isolated from the liver of the double (apolipoprotein E (apoE) and eNOS) knockout (apoE/eNOS-DKO) mice as compared to apoE-/- mice – an animal model of atherosclerosis and hepatic steatosis. Collectively, our proteomic approach revealed the increased expression of proteins related to gluconeogenesis, fatty acids and cholesterol biosynthesis as well as the decreased expression of proteins participated in triglyceride breakdown, cholesterol transport, protein transcription & translation and processing in endoplasmic reticulum (ER). Moreover, one of the most down-regulated proteins were major urinary proteins (MUPs), which are abundantly expressed in the liver and are involved in the regulation of lipid and glucose metabolism as well as mitochondrial function. However, the exact functional consequences of the revealed alterations require further investigation.
