Project description:Cryptorchidism and scrotal heating result in abnormal spermatogenesis but the mechanism(s) proscribing this temperature sensitivity are unknown. It was previously reported that the AKR/N or MRL/MpJ-+/+ mouse testis is more heat resistant than the testis from the C57BL/6 strain. We have attempted to probe into the mechanism(s) involved in heat sensitivity by examining global gene expression profiles of normal and heat-treated testes from C57BL/6, AKR/N and MRL/MpJ-+/+ mice by microarray analysis. In the normal C57BL/6 testis, 415 and 416 transcripts were differentially expressed (at least two-fold higher or lower) when compared to the normal AKR/N and MRL/MpJ-+/+ testis, respectively. The AKR/N and MRL/MpJ-+/+ strains revealed 268 differentially expressed transcripts between them. There were 231 transcripts differentially expressed between C57BL/6 and two purported heat-resistant strains, AKR/N and MRL/MpJ-+/+.

Project description:Epigenetic regulation plays essential role in cell differentiation and dedifferentiation, which are the intrinsic processes involved in regeneration. In order to investigate the epigenetic basis of regeneration capacity, we choose DNA methylation as one of the most important epigenetic mechanisms and the MRL/MpJ mouse as a model of mammalian regeneration reported to exhibit enhanced regeneration response in different organs. We report the comparative analysis of genomic DNA methylation profiles of the MRL/MpJ and the control C57BL/6J mouse. Methylated DNA immunoprecipitation (MeDIP) followed by microarray analysis using Nimblegen “3x720K CpG Island Plus RefSeq Promoter” platform were applied in order to carry out genome-wide DNA methylation profiling covering 20,404 promoter regions. We identified hundreds of hypo- and hypermethylated genes and CpG islands in heart, liver and spleen, and 37 of them in the three tissues. Decreased inter-tissue diversification and the shift of DNA methylation balance upstream the genes distinguish the genomic methylation patterns of the MRL/MpJ mouse from the C57BL/6J. Homeobox genes and a number of other genes involved in embryonic morphogenesis are significantly over-represented among the genes hypomethylated in the MRL/MpJ mouse. These findings indicate that epigenetic patterning might be a likely molecular basis of regeneration capability in the MRL/MpJ mouse.

Project description:CD5 is characterized as an inhibitory co-receptor with important regulatory role during T cell development. To study the molecular mechanism by which CD5 operates, we used quantitative mass spectrometry to analyze the components of the CD5 signaling machinery in primary T cells. In a first set of experiments, CD5-containing complexes were immunoprecipitated from thymocytes of wild-type (WT) C57BL/6 mice. Thymocytes were treated with pervanadate to induce widespread activation of protein tyrosine kinases. Corresponding samples prepared from thymocytes of Cd5−/− mice were used as controls, to discriminate CD5-binding molecules from the background of contaminant proteins. Eight biological replicates were prepared for both conditions, and samples were analyzed in duplicate LC-MS runs. This first set of experiment is presented in TableS1 of the paper, and is associated to the MaxQuant result file “Interactome WT” in the present PX dataset. We analyzed the CD5 interactome at different time of stimulation with pervanadate (1min and 10min) using thymocytes from wild-type (WT) C57BL/6 mice. Corresponding samples prepared from thymocytes of Cd5−/− mice were used as controls. Three biological replicates were prepared for both conditions (WT and KO) and each time point (1min and 10min). This set of experiments is presented in TableS2 of the paper and is associated to the MaxQuant result file “Interactome at 1min and 10min” in the present PX dataset. We checked that the activation of CD5 (phosphorylation sites) and the formation of the signaling complex was comparable in different stimulatory conditions (comparison of WT thymocytes stimulated with either pervanadate or anti-CD3+anti-CD4 antibodies). We also analyzed the binding of CD5 interactors in thymocytes from a c-Cbl-/- mouse model (comparison of WT and c-Cbl-/-thymocytes stimulated with pervanadate). These experiments and the associated experimental design of the comparisons are summarized in TableS3 of the paper, and are based on the MaxQuant result file “Comparison of different stimulatory conditions” in this dataset. To check the phosphorylation status of the CD5 tyrosine residues at different time of stimulation, we analyzed samples immunoprecipitated from thymocytes of wild-type (WT) C57BL/6 mice, following stimulation with anti-CD3+anti-CD4 antibodies for 1min, 3min and 10min. This set of experiment is presented in TableS4 of the paper and is associated to the MaxQuant result file “CD5 pY kinetics” in the present PX dataset. To determine the role of Y429 in the context of CD5 signaling, we expressed a wild-type (CD5tgWt) or a mutated form of CD5, containing a tyrosine to phenylalanine substitution at position 429 (CD5tgY429F) in transgenic mice. We analyzed the CD5 interactome by comparing samples immunoprecipitated from thymocytes of these 2 mice models (following pervanadate stimulation, 6 and 5 biological replicates respectively) with samples prepared in the same way from Cd5−/− mice as controls (6 biological replicates). The results are shown in TableS5 of the paper, and correspond to the MaxQuant result file “interactome CD5tgWt_CD5tgY429F”.

Project description:Previous studies have suggested that the heart may be capable of limited repair and regeneration in response to a focal injury while other studies indicate that the mammalian heart has no regenerative capacity. To further explore this issue, we performed a series of superficial and transmural myocardial injuries in C57BL/6 and MRL/MpJ adult mice. At defined time intervals following the respective injury (Days 3, 14, 30 and 60) we examined cardiac function using echocardiography, morphology, FACS cell sorting for BrdU positive cells and molecular signature using microarray analysis. We observed complete restoration of myocardial function in the superficial MRL cryoinjured heart and significantly less scar formation as compared to the injured hearts of C57BL/6 mice. Following a severe transmural myocardial injury, the MRL mouse has increased survival and decreased ventricular remodeling compared to the C57BL/6 mouse but without evidence of significant regeneration. The cytoprotective program observed in the severely injured MRL heart is in part due to increased vasculogenesis and decreased apoptosis that limits the extension of the injury. We conclude that C57BL/6 and MRL injured hearts have evidence of limited myocardial regeneration, in response to superficial injury, but the improved function and survival observed in the MRL mouse heart following severe injury is not due to significant regenerative processes.
