Project description:Stem cells antigen-1 (Sca-1) is an 18-kDa mouse glycosyl phosphatidylinositol-anchored cell surface protein that has widely been used for isolation of murine hematopoietic stem cells (HSCs). However, recently several studies have reported the expression of this protein in non-HSCs such as the liver, skin and muscles among others. In the current study, we used fluorescence-activated cell sorting (FACS) technique to sort Sca-1+ stem cells from mouse hindlimb muscles. The Sca-1+ cells were divided into two sets first set of Sca-1+ cells were processed for protein extraction immediately after sorting (ex vivo set) while the second set of samples, referred to as in vitro set, were expanded in cell culture after sorting and harvested after two passage and then processed for protein extraction. A high-resolution proteome map of the ex vivo and in vitro sets was generated Orbitrap Fusion Tribrid Mass Spectrometer. In total, the analysis led to the identification of 5,581 protein groups.

Project description:The study was a comparison of gene expression using RNA-seq. We analyzed the stem and progenitor cells from WT and Vav-cre+ Tet2fl/fl Flt3-ITD (T2F3) mice. We isolated stem cells LSK (lin- sca+ kit+) and granulocyte-macrophage progenitors GMP (lin- sca- kit+ fcgr+ cd34+) cells from bone marrow. Comparisons were made across genotypes WT vs. T2F3 and cell types LSK vs. GMP. Comparison of WT and Tet2-/-Flt3ITD bone marrow stem and progenitor cells.

Project description:We identified genes expressed in mouse skeletal muscle, during the process of muscle regeneration after injury, which are dysregulated in the absence of Mef2a expression. MEF2A is a member of the evolutionarily conserved MEF2 transcription factor family which has known roles in cardiac muscle development and function, but is not well studied in skeletal muscle. We performed a comparison of gene expression profiles in wild type and MEF2A knockout tibialis anterior muscle, seven days post-injury with cardiotoxin. The results indicated that a variety of genes expressed during muscle regeneration, predominantly microRNAs in the Gtl2-Dio3 locus, are dysregulated by the loss of MEF2A expression. Skeletal muscle RNA used in the present study included the following two sample groups: (WT) pooled total RNA from tibialis anterior muscle taken from 5 wild type mice at seven days post-injury with 10uM cardiotoxin; (KO) pooled total RNA from tibialis anterior muscle taken from 5 Mef2a knockout mice at seven days post-injury with 10uM cardiotoxin. All mice were between 2-4 months of age. Both male and female mice were used.

Project description:Utilizing glycerol and cardiotoxin (CTX) injections in the tibialis anterior muscles of M. musculus provides models of skeletal muscle damages followed by skeletal muscle regeneration. In particular, glycerol-induced muscle regeneration is known to be associated with ectopic adipogenesis. We characterized genome-wide expression profiles of tibialis anterior muscles from wild-type mice injured by either glycerol or CTX injection. Our goal was to detect gene expression changes during the time course of glycerol-induced and CTX-induced muscle regeneration models, that can lead to ectopic adipocyte accumulation. Tibialis anterior muscle of 12 week old wildtype C57BL/6J male mice injected i.m with either glycerol or CTX were collected 3, 7, 14 or 21 days after injection. 6 biological replicates were used for each time points. Please note that a few replicate samples did not pass QC test, thus, were removed from the submission. Unchallenged tibialis anterior muscles from a group of 5 wildtype C57BL/6J mice were also as a control. Total RNA was extracted, QCed and hybridized to Affymetrix microarrays.

Project description:Small intestinal innate lymphoid cells (ILCs) are known to regulate intestinal epithelial cell homeostasis and to help prevent pathogenic bacterial infections, by producing IL-22. However, other functions of these cells and the lineal relationship between ILCs and lymphoid or myeloid cells have not been clear. We performed a global gene expression analysis to examine which genes are highly expressed by small intestinal ILCs (Lin-c-Kit+Sca-1- cells) compared with non-ILCs (Lin-c-Kit-Sca-1- cells). To examine the gene expression profiles of ILCs within the small intestinal lamina propria (LP), we isolated Lingeage (Lin)-c-Kit+Sca-1- cells [consisting of NKp46+ ILC22 (Lin-c-Kit+Sca-1-NKp46+ cells) and LTi-like ILC (Lin-c-Kit+Sca-1-CD4+ cells)] as the ILC population, and Lin-c-Kit-Sca-1- cells as the non-ILC population, from the small intestinal LP of 8 week-old mice by FACS, then compared the gene expression profiles between these two populations by microarray analysis.

Project description:PGC1b transgenic mice were generated to selectively over-express PGC1b in skeletal muscles using human skeletal alpha-actin gene promoter. The gene expression profiles were collected from Tibialis anterior (TA) muscles of wild type (WT) and PGC1b transgenic (TG) mice. Tibialis anterior muscles from three month old WT and PGC1b transgenic male mice.

Project description:Tendon is a highly aligned connective tissue, in which the macro-structure consists of collagen-rich fascicles surrounded by interfascicular matrix (IFM). In a series of recent studies in equine tissue, we have demonstrated specialisation of tendon composition, structure and mechanics to achieve the tendon’s functional requirements, specifically reporting extensive specialisation of the IFM region in the energy storing superficial digital flexor tendon. We have also demonstrated loss of functional specialisms with ageing, leading to a hypothesised new paradigm for tendinopathy, focused on the importance of the IFM. However, to date, there have been no studies focused on structure-function specialisation or the IFM in functionally distinct human tendons. Here, we compare the positional anterior tibialis tendon and energy storing Achilles tendon, performing a detailed analysis of the composition and mechanical properties of both fascicle and IFM regions, to test the hypothesis that the IFM in the energy storing Achilles tendon has specialised composition and mechanical properties, and that these specialisations are lost with ageing. We demonstrate that the IFM is specialised in the energy storing Achilles tendon, with greater elasticity and fatigue resistance than in the positional anterior tibialis tendon. While there were few age-related alterations in mechanics, we did identify age-related alterations in the IFM proteome of the Achilles tendon specifically, which is predicted to be regulated by TGF-beta signalling and may be responsible for the trend towards decreased fatigue resistance observed in the Achilles IFM with ageing.

Project description:To gain new insights into molecular changes in skeletal muscle aging and disease with a special focus on differential alternative splicing and senescence, we performed RNA-seq on tibialis muscles from 15 months old (adult, a) and 27 months old (old, o) rats. Whole (w) muscle samples were prepared for both age groups (w/a and w/o). Additionally, for both age groups, muscle fibers were isolated. For adult rats, this resulted in one group (f/a). For old rats, fibers were subjected to Laser capture microdissection guided by expression of aging markers Tmem158 and Cdkn1a, giving rise to two groups, aging marker-positive fibers (f/o+) and aging marker-negative fibers (f/o-). The entire experiment comprises 5 groups (w/a, w/o, f/a, f/o+, f/o-), with 5 animals per group, ie. 25 samples total.
