Phosphoproteomic analysis of EDL muscle

ABSTRACT: The 5α-DHT-mediated muscle-strengthening effects through the activation of GPR133 were found to be AR-independent. To elucidate the underlying mechanism, we stimulated isolated EDL muscles with 5α-DHT and then performed a phosphoproteomic analysis.

Androgens, such as 5α-dihydrotestosterone (5α-DHT), regulate numerous functions by binding to nuclear androgen receptors (ARs) and potential unknown membrane receptors. Here, we report that the androgen 5α-DHT activates membrane receptor GPR133 in muscle cells, thereby increasing intracellular cyclic AMP (cAMP) levels and enhancing muscle strength. Further cryoelectron microscopy (cryo-EM) structural analysis of GPR133-Gs in complex with 5α-DHT or its derivative methenolone (MET) reveals the str ...[more]

Proteomic and phosphoproteomic of C18ORF25 KO skeletal muscle following electrical contraction

Project description:We recently identified C18ORF25 as a new exercise-regulated phophoprotein. To investigate potential in vivo functions of C18ORF25, we used CRISPR/Cas9 to generate a whole-body knock-out (KO) mouse model on a C57BL/6J background. Proteomic analysis was performed to identify potental changes in the proteome. To gain further insights into the possible signalling pathways regulated by C18ORF25, Soleus muscles from WT and KO mice (n=4) were isolated, and the muscle from one leg was maintained at resting tension with no stimulation as a control while the muscle from the contralateral leg was subject to electrical stimulation ex vivo. Muscles were quickly snap frozen and subject to single-shot label-free phosphoproteomic analysis to compare the signalling responses between the genotypes.

Mouse Muscle Stem Cell Proteome during Activation and CPEB1 Dependent Proteome in Mouse Muscle Stem Cell

Project description:Muscle Stem Cells or satellite cells (SCs) are required for muscle regeneration. In resting muscles, SCs are kept in quiescence. After injury, SCs undergo rapid activation, proliferation and differentiation to repair damaged muscles. The transcriptome alteration during SC activation is well characterized. While transcriptome is not exactly represent proteome because of post-transcriptional regulations such as miRNA induced gene silencing. However, little is known about SC proteome. We obtained quisecent SCs (QSCs) and freshly isolated SCs (fiSCs, early activated SCs) and activated SCs (ASCs) for high resolution mass spectrometry Bruker timsTOF Pro. Thus, we uncovered the QSC proteome. By comparison of QSC proteome to fiuSCs proteome or ASCs proteome, we identified the pathways that are differentially expressed between them. Forthermore, we characterized a translational regulator CPEB1 reprogrammed translation landscape for SC activation.

Global phosphoproteomic profiling of skeletal muscle in ovarian-hormone deficient mice

Project description:Phosphorylation is important in skeletal muscle development, growth, regeneration, and contractile function. Alterations in the skeletal muscle phosphoproteome due to aging have been reported in males; however, studies in females are lacking. We have demonstrated that estrogen deficiency decreases muscle force which correlates with decreased myosin regulatory light chain phosphorylation. Thus, we questioned whether the decline of estrogen in females that occurs with aging might alter the skeletal muscle phosphoproteome. C57BL/6J female mice randomly assigned to a sham-operated (Sham) or ovariectomy (Ovx) group to investigate the effects of estrogen deficiency on skeletal muscle protein phosphorylation in a resting, non-contracting condition. After 16 weeks of estrogen deficiency, the tibialis anterior muscle was dissected and prepped for label-free nano-liquid chromatography tandem mass spectrometry phosphoproteomic analysis. We identified 4,780 phosphopeptides in tibialis anterior muscles of ovariectomized (Ovx) and Sham-operated (Sham) control mice. Further analysis revealed 647 differentially regulated phosphopeptides (Benjamini – Hochberg adjusted p-value < 0.05 and 1.5-fold change ratio) that corresponded to 130 proteins with 22 proteins differentially phosphorylated (3 unique to Ovx, two unique to Sham, six upregulated, and 11 downregulated). Differentially phosphorylated proteins associated with the sarcomere, cytoplasm, and metabolic and calcium signaling pathways were identified. Our work provides the first global phosphoproteomic analysis in females and how estrogen deficiency impacts the skeletal muscle phosphoproteome.

Gene profiling of quiescent and activated skeletal muscle satellite cells by an in vivo approach

Project description:The satellite cell of skeletal muscle provides a paradigm for quiescent and activated tissue stem cell states. We have carried out transcriptome analyses by comparing satellite cells from adult skeletal muscles, where they are mainly quiescent, with cells from growing muscles, regenerating (mdx) muscles, or with cells in culture, where they are activated. Our study gives new insights into the satellite cell biology during activation and in respect with its niche. We used microarrays to study the global programme of gene expression underlying adult satellite cell quiescence compared to activation states and to identify distinct classes of up-regulated genes in these two different states Skeletal muscle satellite cells were isolated by flow cytrometry using the GFP fluorescence marker from Pax3GFP/+ mice skeletal muscle. The transcriptome of quiescent satellite cells from adult Pax3GFP/+ muscle was compared to the transcriptome of activated satellite cells obtained from three different samples: 1) regenerating Pax3GFP/+:mdx/mdx muscle (Ad.mdx) , 2) growing 1 week old Pax3GFP/+ muscle (1wk), and 3) adult Pax3GFP/+ cells after 3 days in culture (Ad.cult).

Profiling of mouse muscle stem cells aging and activation upon skeletal muscle injury

Project description:Utilizing glycerol intramuscular injections in M. musculus provide a models of skeletal muscle damage followed by skeletal muscle regeneration. In particular, glycerol-induced muscle injury triggers accute activation of skeletal muscle stem cells, called satellite cells. However, aging dramatically impairs the regenerative capacity of satellite cells. We characterized genome-wide expression profiles of young and old satellite cells in the non-proliferative and activated state, freshly isolated to non-injured or damaged muscles, respectively. Our goal was to uncover new regulatory signaling specific to satellite cells entry into the activation and myogenic program that are affected with age. Satellite cells were isolated in either quiescent / non-proliferative or activated state from uninjured or 3 days after glycerol-induced injury of tibialis anterior, gastrocnemius and quadriceps, respectively. Young (2-4 months old) and old (20-24 months old) wildtype C57BL/6J male were used, with five to six biological replicates per group.

Natural aging and ovariectomy induces parallel phosphoproteomic alterations in skeletal muscle of female mice

Project description:The loss of skeletal muscle strength mid-life in females is associated with the decline of estrogen. Here, we questioned how estrogen deficiency might impact the overall skeletal muscle phosphoproteome after contraction, as force production induces phosphorylation of several muscle proteins. Phosphoproteomic analyses of the tibialis anterior muscle after contraction in two mouse models of estrogen deficiency, ovariectomy (Ovariectomized [Ovx] vs Sham) and natural aging-induced ovarian senescence (Older Adult [OA] vs Young Adult [YA]), identified a total of 2,593 and 3,507 phosphopeptides in Ovx/Sham and OA/YA datasets, respectively. Further analysis of estrogen deficiency-associated proteins and phosphosites identified 66 proteins and 21 phosphosites from both datasets. Of these, 4 estrogen deficiency-associated proteins and 4 estrogen deficiency-associated phosphosites were significant and differentially phosphorylated or regulated, respectively. Comparative analyses between Ovx/Sham and OA/YA using Ingenuity Pathway Analysis (IPA) found parallel patterns of inhibition and activation across IPA-defined canonical signaling pathways and physiological functional analysis, which were similarly observed in downstream GO, KEGG, and Reactome pathway overrepresentation analysis pertaining to muscle structural integrity and contraction, including AMPK and calcium signaling. IPA Upstream regulator analysis identified MAPK1 and PRKACA as candidate kinases and calcineurin as a candidate phosphatase sensitive to estrogen. Our findings highlight key molecular signatures and pathways in contracted muscle suggesting that the similarities identified across both datasets could elucidate molecular mechanisms that may contribute to skeletal muscle strength loss due to estrogen deficiency.
