Project description:BALB/c mice are susceptible to proteoglycan (PG) aggrecan-induced arthritis (PGIA), a murine model of rheumatoid arthritis (Glant,T.T. and Mikecz,K., Proteoglycan aggrecan-induced arthritis. A murine autoimmune model of rheumatoid arthritis. Methods Mol.Med. 2004. 102: 313-338.). However, there are marked differences among BALB/c colonies (maintained by different vendors at different locations) in PGIA onset and severity, which could be the result of subtle variations in their genetic background. In the present microarray study, we have identified differences among BALB/c colonies, and an altered immunization-related gene expression pattern in PGIA model. Experiment Overall Design: In this study we compared the gene expression profile of 12 spleens from PG-immunized (RNA was isolated 12 days after immunization) and naive mice from BALB/cJ and BALB/cByJ colonies (3-3 from each group), then made comparisons between colonies and based on immunization.

Project description:Autoimmune arthritis was induced in BALB/c mice with three consecutive PG-injections. B cells were affinity purified from arthritic and contol (adjuvant injected - non-arthritic) mice and isolated total RNA samples were analyzed on microarray platforms. Several hundred disease-associated gene expression changes were detected in B cells
Project description:BALB/c mice are susceptible to proteoglycan (PG) aggrecan-induced arthritis (PGIA), and the absence of TSG-6 further increases susceptibility and local inflammatory reactions, including neutrophil invasion into the joints. To gain insight into the mechanisms of TSG-6 action, synovial fibroblasts were isolated from wild-type and TSG-6-KO mice, cultured and exposed to various agents affecting either the TSG-6 expression and/or modify the intracellular function of TSG-6. In the present microarray studies, we have identified differences in gene expression by fibroblasts isolated from wild-type or TSG-6-KO mice Keywords: Genetic modification
Project description:BALB/c mice develop peripheral arthritis (PGIA) and spondyloarthropathy (PGIS) upon repeated intraperitoneal injections of human cartilage proteoglycan (PG) aggrecan. The aim of the present study was to identify spondylitis-specific genes by comparing intervertebral disc (IVD) RNA samples from spondyloarthropathic and naïve BALB/c mice. Keywords: Genetic modification
Project description:BALB/c mice develop peripheral arthritis (PGIA) and spondyloarthropathy (PGIS) upon repeated intraperitoneal injections of human cartilage proteoglycan (PG) aggrecan. The aim of the present study was to identify spondylitis-specific genes by comparing intervertebral disc (IVD) RNA samples from spondyloarthropathic and naM-CM-/ve BALB/c mice. Keywords: Genetic modification We compared the gene expression data of 5 spondyloarthropathic and 3 naM-CM-/ve (control) mice.
Project description:Autoimmune arthritis was induced by three consecutive PG injections. B cells were affinity purified from mice and methylated DNA fractions were enriched by methylated-CpG island recovery assay (MIRA) method and investigated on microarray platforms. Several hundred differentially methylated regions were detected in the investigated B cell epigenomes
Project description:This study identifies molecular changes in hematopoietic stem cells (HSC) isolated from mice with chronic autoimmune arthritis induced using the collagen-induced arthritis (CIA) model.
