Project description:Age as the primary rise factor could be play an important role in incidence and development of osteoarthritis. A few studies have confirmed some tissue specific lncRNA were associated with development of osteoarthritis. But if age related lncRNA would be involved in pivotal post-transcriptional gene regulation in osteoarthritis is unclear. In view of this, we have an idea that several age-related lncRNA would be screened from the rat knee cartilage at different development ages by lncRNAs Microarray analysis. We used microarrays to detail the global programme of gene expression underlying the rat knee cartilage and identified distinct classes of age-related lncRNA during this process. The rat knee articular cartilage were selected at successive stages of the rat developmental for RNA extraction and hybridization on Affymetrix lncRNA arrays. We sought to obtain homogeneous populations of cartilage at each developmental stage in order to increase the temporal resolution of expression profiles. To that end, we hand-selected cartilage according to the rat developmental stages, i.e. seven time-points: newborn (T0), youth(T1), adult (T2), early-stage elderly(T3) and latter-stage elderly(T4).

Project description:Age as the primary rise factor could be play an important role in incidence and development of osteoarthritis. Several studies have confirmed some tissue specific microRNA were associated with development of osteoarthritis. But if age related microRNA or miRNA cluster would be involved in pivotal post-transcriptional gene regulation in osteoarthritis is unclear. In view of this, we have an idea that several age-related miRNAs would be screened from the rat knee cartilage at different development ages by miRNAs Microarray analysis. We used microarrays to detail the global programme of gene expression underlying the rat knee cartilage and identified distinct classes of age-related miRNAs during this process.

We sought to obtain homogeneous populations of cartilage at each developmental stage in order to increase the temporal resolution of expression profiles. To that end, we hand-selected cartilage according to the rat developmental stages, i.e. seven time-points: newborn (T0), childhood (T1), youth(T2), adult (T3), middle-aged (T4) early-stage elderly(T5) and latter-stage elderly(T6). The objective of the study is to identify miRNA profile of knee articular cartilage at different developmental ages in rats. Total RNA were extracted from the knee articular cartilage of Sprague-Dawley rats at postnatal day 0(T0), week1(T1), week 4(T2), mon3(T3), mon 6(T4), mon 12(T5), and mon 18(T6). The microRNA profile in the specimens was detected with the Affymetrix GeneChip® miRNA 3.0 Array.

Project description:We established 3 types of primary xenograft models (KURC;Kyoto University Renal Cancer-1,2,3) derived from human renal cell carcinoma tissues, and 40 mg/day of sunitinib was orally administered. We performed microarray analysis to compare the gene expression profile of sunitinib-treated primary xenograft tumors (sensitive or resistant status) with that of vehicle-treated.

Project description:In this project, we generated chronic sunitinib-treated 786-O cell, a renal cell carcinoma cell line. In order to investigate the possible effect of GPR30 agonist, G-1, on the growth-inhibtion related signaling pathways, we treated either parental both parental and chronic sunitinib-treated 786-O cells were treated either by vehicle-only (i.e. 0.1% DMSO) or 2 μM G-1 for 48 h. Therefore, there were three groups for comparison, including G-1 treatment (G-1 vs. parental), chronic sunitinib-treatment (SunR vs. parental), and G-1 treatment in SunR cells (SunR&G-1 vs. parental).

Project description:ObjectiveDuring skeletal growth, the articular cartilage expands to maintain its cover of bones in joints, however, it is unclear when and how cartilage grows. We aim to determine the expanding growth pattern and timing across the tibia plateau in human knees.DesignSix human tibia plateaus (2 healthy, 2 with osteoarthritis, and 2 with posttraumatic osteoarthritis) were used for full-depth cartilage sampling systematically across the joint surface at 12 medial and 4 lateral sites. Methodologically, we took advantage of the performed nuclear bomb tests in the years 1955 to 1963, which increased the atmospheric 14C that was incorporated into human tissues. Cartilage was treated enzymatically to extract collagen, analyzed for 14C content, and year at formation was determined from historical atmospheric 14C concentrations.ResultsBy age-determination, each tibia condyle had central points of formation surrounded by later-formed cartilage toward the periphery. Furthermore, the tibia plateaus contained collagen with 14C levels corresponding to mean donor age of 11.7 years (±3.8 SD). Finally, the medial condyle had lower 14C levels corresponding to formation 1 year later than the lateral condyle (P = 0.009).ConclusionsHuman cartilage on the tibia plateau contains collagen that has experienced little if any turnover since school-age. The cartilage formation develops from 2 condyle centers and radially outward with the medial condyle finishing slightly later than the lateral condyle. This suggests a childhood programmed cartilage formation with a very limited adulthood collagen turnover.

Project description:Objective: To examine the changes in tibial plateau cartilage in relation to body mass index (BMI) in patients with end-stage osteoarthritis (OA). Design: Knees were obtained from 23 OA patients (3 non-obese, 20 obese) at the time of total knee replacement. RNA prepared from cartilage was probed for differentially expressed (DE) gene transcripts using RNA microarrays and validated via real-time PCR. Differences with regard to age, sex, and between medial and lateral compartments were also queried. Results: Microarrays revealed that numerous transcripts were significantly DE between non-obese and obese patients (≥1.5-fold) using pooled and separate data from medial and lateral compartments. Correlation analyses showed that 706 transcripts (459 positively, 247 negatively) were significantly correlated with BMI. Among these, HS3ST6, HSD17B12, and FAM26F were positively correlated while STAC3, PRSS21, and EDA were negatively correlated. Differentially correlated transcripts represented important biological processes e.g. cellular metabolic processes, anatomical structure morphogenesis and cellular response to growth factors. Although age and sex had some effect on transcript expression, most intriguing results were observed for comparison between medial and lateral compartments. Transcripts (MMP13, CLEC3A, MATN3, EPYC, SCARNA5, COL2A1) elevated in the medial compartment represented skeletal system development, cartilage development, collagen and proteoglycan metabolism, and extracellular matrix organization. Likewise, transcripts (SELE, CTSS, VSIG4, F13A1, and STEAP4) repressed in medial compartment represented host immune response, cell migration, wound healing, cell proliferation and response to cytokines. PCR data confirmed expression of DE transcripts. Conclusions: This study supports molecular interaction between obesity and OA and implies that BMI is an important determinant of transcript-level changes in cartilage.

Project description:Immunodeficient RAG1-/- mice bearing MDA-MB231-LUC+ tumors of 50-70 mm3 were daily administrated by gavage with vehicle (containing, 0.5% carboxymethylcellulose, 1.8 % NaCl, 0.4 % Tween-80, 0.9 %. benzyl alcohol, and ultrapure water adjusted to pH 6.0) or sunitinib (40mg/kg/day) for 30 days followed by treatment withdrawal for 3-4 weeks to allow the tumor regrowth until reaching the same volume as that of the vehicle treated group. Mice were sacrificed when tumor reached the volume of 350-400 mm3 and RNAs of two tumors from two different mice treated with sunitinib or vehicle were extracted.
