Heart and skeletal muscle of young adult and early aging mice

ABSTRACT: Left cardiac ventricles and quadriceps femoris muscles were collected from young adult (16-17 wk) and early aging (86 wk) C57BL6/J mice (n=4, 2 male 2 female). Proteins were extracted in 200 µL RIPA buffer and Halt protease/phosphatase inhibitor with a hand-held sonicator followed by centrifugation, reduced with dithiothreitol, alkylated with iodoacetamide, then digested with modified sequencing grade trypsin overnight at 37degC using a filter-assisted sample preparation protocol. The peptides were fractionated using Thermo high-pH reversed phase columns into 8 fractions. Label-free bottom-up mass spectrometry was performed using data dependent acquisition on a Thermo Orbitrap Q-Exactive HF instrument using typical settings.

Biphasic GISTs reveal the early mechanisms in GIST high-grade transformation

Project description:To study the very early changes in high-grade transformation of gastrointestinal stromal tumors (GISTs), 17 biphasic GISTs, with a transitional status in which low-grade and high-grade parts coexist, were collected from 263 continuous cases (6.5%). Nucleic acids of each part were retrieved for gene expression profiling.

Alterations of rat liver tissue and hepatic stellate cells during ageing

Project description:Livers for tissue preparation and HSC isolation were derived from 2 and 22 months old male Wistar rats from Janvier Labs (France). Samples from three different lobes (median lobe, left lateral lobe, right lateral lobe) of each liver were collected and pooled for tissue analysis by gene expression. To isolate HSC, the livers were digested with enzyme solutions and HSC were enriched by density gradient centrifugation. HSC were purified by fluorescence-activated cell sorting using their typical retinoid fluorescence emitted after UV-light excitation. The sorted HSC were collected in IMDM supplemented with 10% FCS and 1 % antibiotic-antimycotic solution and cultured for 24 hours. Total RNA of HSC and whole liver tissue from 3 young and 3 old rats was extracted using the Qiagen RNeasy Mini Kit. RNA samples obtained from cultured HSC and whole liver tissues were sent to IMGM Laboratories (Martinsried, Germany) for gene expression analyses by microarrays (Affymetrix, GeneChip Rat Gene 2.0 ST Array, Thermo Fisher Scientific) in triplicates for each age group. The array data were processed by the Transcriptome Analysis Console 3.0 (Thermo Fisher Scientific).

Human primary meningioma vs. non-neoplastic adult meningeal tissue

Project description:Meningiomas are common brain tumors that are classified into three World Health Organization grades (Grade I: benign, Grade II: atypical and Grade III: malignant) and are molecularly ill-defined tumors. The purpose of this study was identify microRNA (miRNA) molecular signatures unique to the different grades of meningiomas correlating them to prognosis. We have used a miRNA expression microarray to show that meningiomas of all three grades fall into two main molecular groups designated “benign” and “malignant” meningiomas. While all typical meningiomas fall into the benign group and all anaplastic meningiomas fall into the malignant group, atypical meningiomas distribute into either one of these groups. We have identified a miRNA signature that distinguishes benign meningiomas from malignant meningiomas.

Hepatitis C virus induces HuR relocalization by coordinating PKC-δ and AMPK-α function

Project description:Huh7.5 cells were transfected with HCV-JFH1 RNAand harvested after 48h of transfection. Total proteins were extracted in IP lysis buffer (Pierce, Thermo Scientific) containing 1× halt-protease and phosphatase inhibitor cocktail (Thermo Fisher Scientific, USA) with intermediate vortexing followed by mild sonication. The lysate was centrifuged at 14,000 × g for 30 min at 4 °C. The supernatant was quantified by the BCA method (Thermo Fisher Scientific, USA). An equivalent amount (4 mg) of proteins from each condition was incubated with 3g of anti-HuR antibody for overnight at 4 °C. The immunocomplex was captured by using protein G Sepharose 4 fast flow beads (17-0618-01/ GE Healthcare). The immunoprecipitated complex was washed two times with IP lysis buffer and one time with mili-Q. Bound protein complexes were eluted in 50 µl SDS-PAGE 2X Laemmli sample buffer. The samples were resolved on 12% SDS–PAGE and stained with Coomassie stain (0.1% w/v). The gel was subjected to further in-gel mass spectrometry analysis.

Genome-wide transcriptional alterations during vascular growth in skeletal muscles of type 2 diabetic mice in response to femoral artery ligation

Project description:Diabetes is a major risk factor of cardiovascular disease including coronary and peripheral arterial disease, attributed to impaired arteriogenesis and angiogenesis. Mechanisms behind them are poorly understood due to the complexity of these processes in presence of diabetes. To understand the cellular and molecular mechanisms underlying impaired adaptive vascular responses in type 2 diabetic (T2DM) mouse models of hindlimb ischemia using Genome-wide mRNA sequencing.In response to FAL, collateral density and lumen area were significantly reduced in adductor muscles of T2DM mice at day 7 and 14 days post-FAL. mRNA sequencing suggested an altered gene expression typical for monocyte and macrophage (Mϕ) subsets. Similarly, gene expressions typical of dendritic cell and lymphocyte were altered in adductor muscles of T2DM mice. Ischemic muscles of T2DM mice displayed impaired angiogenesis as revealed by endothelial staining. mRNA sequencing suggested downregulation of crucial genes implicated in angiogenesis and differential expression of genes typical for Mϕ subsets. Immunohistochemistry analysis corroborated with the mRNA sequencing analysis, suggesting an altered Mϕ polarization behind the impaired arteriogenesis and angiogenesis seen in T2DM mouse models of hindlimb ischemia.

Expression data during plantaris muscle hypertrophy induced by synergist ablation in young adult mice

Project description:Global gene expression patterns were determined from microarray results on day 1, 3, 5, 7, 10 and 14 during plantaris muscle hypertrophy induced by synergist ablation in young adult mice (5 months). For each time point, two Affymetrix chips (Mouse Gene 1.0 ST) were used with 100 ng of total RNA derived from a pooled sample of either the right or left plantaris muscles from six animals.

Expression data from mouse muscle

Project description:The knock-out of calpain 3 (C3KO) is a murine model for calpainopathies wich shows a mild dystrophic phenotype with signs of muscle degeneration. Adult (A) mice show a more severe phenotype than young (Y) mice which only present inflammatory infiltrates in most severely affected muscles, such as the soleus. Other muscles (e.g. quadriceps) are much less affected. We used microarray technology to compare gene expression profiles of young and adult muscles in wild-type (wt) and C3KO mice, in two types of muscle: soleus (affected) and quadriceps (much less affected). 11 wt (7 adult and 4 young) and 11 C3KO (7 adult and 4 young) mice were used in this study for RNA extraction and hybridization on Affymetrix microarrays. The soleus and the quadriceps muscles were obtained from each mouse. All mice were males.
