Project description:Trem2 is a single-pass transmembrane receptor of the immunoglobulin superfamily and is primarily expressed in myeloid cells. Cells from injured and uninjured knee joints of wildtype C57BL/6 mice and Trem2 KO mice were sequenced to determine if Trem2 plays a role in macrophage differentiation or function after joint injury.

Project description:Osteoarthritis (OA) of the hand is a common disease resulting in pain and impaired function. The pathogenesis of hand OA (HOA) is elusive and models to study it have not been described so far. Culture of chondrocytes is a model to study the development of cartilage degeneration, which is a hallmark of OA and well established in OA of the knee and hip. In the current study we investigated the feasibility human chondrocyte culture derived from proximal interphalangeal (PIP) finger joints of dissecting room cadavers. Index and middle fingers without signs of osteoarthritis were obtained from 30 cadavers using two different protocols. Hyaline cartilage from both articulating surfaces of the proximal interphalangeal (PIP) joint was harvested and digested in collagenase. Cultured chondrocytes were monitored for contamination, viability, and expression of chondrocyte specific genes. Chondrocytes derived from knee joints of the cadavers were cultured under identical conditions. Gene expression comparing chondrocytes from PIP and knee joints was carried out using Affymetrix GeneChip Human 2.0 ST arrays. The resulting differentially expressed genes were validated by real-time PCR and immunohistochemistry.Chondrocytes harvested up to 101 hours after death of the donors were viable. mRNA expression of collagen 2A1, aggrecan and Sox9 was significantly higher in chondrocytes as compared to cultured fibroblasts. Comparison of gene expression by chondrocytes from PIP and knee joints yielded 528 differentially expressed genes. Chondrocytes from the same joint region had a higher grade of similarity than chondrocytes of the same individual. These results were validated using real-time PCR and immunohistochemistry.We demonstrate for the first time a reliable method for culture of chondrocytes derived from PIP joints. PIP chondrocytes show a specific gene expression pattern and could be used as tool to study cartilage degeneration in HOA. Three samples of cultured chondrocytes from knee and proximal interphalangeal finger joints were compared. Gene expression of the four most differentially regulated genes was confirmed by real-time PCR in 10 independent samples.

Project description:We found that the severity of the K/BxN serum-transfer arthritis model is higher in Sema3B deficient (Sema3b-/-) mice. Here we analyzed by RNAseq the tranciptional differences in the joints of these mice group. We used four groups: 1) WT control (non-arthritic); 2) Sema3b-/- control; 3) WT arthritis day 9; 4) Sema3b-/- artritis day 9.

Project description:The effects of loss of the large neutral amino acid transporter Slc7a5 (aka Lat1) on mouse embryonic development were investigated. Slc7a5 fl/fl mice harbouring two copies of the Slc7a5 targeted allele (exon 1 of Slc7a5 flanked with two loxP sites), were crossed with a mouse line ubiquitously expressing cre recombinase under the Bal1 promoter (Bal1-cre) to obtain a global Slc7a5 knockout mouse (Poncet et al. 2014 PLoS One 9: e89547). Heterozygous Slc7a5+/- C57Bl/6 mice were viable and fertile and were bred free of Bal1-cre in subsequent generations. Slc7a5 -/- embryos were obtained by inter-crossing heterozygotes and a phenotype was apparent by E9.5. To identify the first cellular processes affected by Slc7a5 loss RNAseq was carried out to compare transcriptomes of null and wildtype E8.5 embryos.

Project description:GOAL: Identification of genes and/or pathways involved in the pathogenesis of animal models of Rheumatoid Arthritis (RA). Total RNA samples were extracted from synovial fibroblast ex vivo cultures or whole joints (J), isolated from arthritic mice (197, DARE) and their corresponding normal (F1, wt) littermates. Fluorescent-labeled cRNA probes were utilized to hybridize (in duplicates for 197, indicated by "new") the Affymetrix Mu11K oligonucleotide DNA chipset (A+B). In detail the samples are:<br> <table> <tr> <td> <u>Animal model</u> </td> <td> <u>Sample source</u> </td> <td> <u>Sample name</u> </td> </tr> <tr> <td> Tg197 </td> <td> Tg197 ex-vivo cultured synoviocyte populations </td> <td> 197 </td> </tr> <tr> <td> Tg197 </td> <td> Tg197 ex-vivo cultured synoviocyte populations </td> <td> 197new </td> </tr> <tr> <td> Tg197 </td> <td> wt ex-vivo cultured synoviocyte populations </td> <td> F1 </td> </tr> <tr> <td> Tg197 </td> <td> wt ex-vivo cultured synoviocyte populations </td> <td> F1new </td> </tr> <tr> </tr> <tr> <td> Tg197 </td> <td> Tg197 whole joints </td> <td> 197J </td> </tr> <tr> <td> Tg197 </td> <td> Tg197 whole joints </td> <td> 197Jnew </td> </tr> <tr> <td> Tg197 </td> <td> wt whole joints </td> <td> F1J </td> </tr> <tr> <td> Tg197 </td> <td> wt whole joints </td> <td> F1Jnew </td> </tr> <tr> </tr> <tr> <td> DARE </td> <td> DARE ex-vivo cultured synoviocyte populations </td> <td> DARE </td> </tr> <tr> <td> DARE </td> <td> wt ex-vivo cultured synoviocyte populations </td> <td> wt </td> </tr> <tr> <td> DARE </td> <td> DARE whole joints </td> <td> DAREJ </td> </tr> <tr> <td> DARE </td> <td> wt whole joints </td> <td> wtJ </td> </tr> </table> <br> Submitted files carry the extension A or B, corresponding to the subArrays of chipset Mu11K. Arthritic samples were always compared with the corresponding wt sample and not to a common reference chip.

Project description:Injuries to the anterior cruciate ligament (ACL) often result in post-traumatic osteoarthritis (PTOA). PTOA accounts for ~12% of all osteoarthritis (OA) cases, yet the mechanisms contributing to OA after joint injury are not well understood. To better understand the molecular mechanisms behind PTOA development following ACL injury, we profiled ACL injury-induced gene expression changes in knee joints of three mouse strains with varying susceptibility to PTOA: STR/ort (highly susceptible), C57BL/6 (moderately susceptible) and super-healer MRL/MpJ (not susceptible) and identified genes differentially expressed between these strains at 0-day [before injury], 1-day, 1-week, and 2-weeks post-injury. This study highlights many new potential therapeutic targets and OA biomarkers.
