Molecular serum and urine marker repertoire supporting clinical research on joint diseases

The need for improved analytical techniques in the study of slow, degenerative diseases such as rheumatoid arthritis and osteoarthritis has driven major efforts aimed at identifying biochemical markers of pathological processes in both diseases. A series of novel biochemical markers has surfaced and…

Identification of the calcitonin receptor in osteoarthritic chondrocytes

BACKGROUND:
Preclinical and clinical studies have shown that salmon calcitonin has cartilage protective effects in joint degenerative diseases, such as osteoarthritis (OA). However, the presence of the calcitonin receptor (CTR) in articular cartilage chondrocytes is yet to be identified. In this st…

Characterization of an Ex vivo Femoral Head Model Assessed by Markers of Bone and Cartilage Turnover

OBJECTIVE:
The pathophysiology of osteoarthritis involves the whole joint and is characterized by cartilage degradation and altered subchondral bone turnover. At present, there is a need for biological models that allow investigation of the interactions between the key cellular players in bone/cart…

Oral salmon calcitonin reduces cartilage and bone pathology in an osteoarthritis rat model with increased subchondral bone turnover

OBJECTIVES:
Traumatic osteoarthritis (OA) is possibly augmented by effects from loss of sex hormones. Salmon calcitonin is shown to reduce OA pathogenesis and bone resorption. We investigated the effects of oral salmon calcitonin treatment and ovariectomy on cartilage and bone pathology in a trauma…

Enzyme-linked immunosorbent assay (ELISAs) for metalloproteinase derived type II collagen neoepitope, CIIM--increased serum CIIM in subjects with severe radiographic osteoarthritis

OBJECTIVES:
In joint degenerative diseases, the collagens are degraded by matrix metalloproteinases and protein fragments are released to serum as potential biomarkers.

METHODS:
A collagen type II specific neoepitope, CIIM, was identified (…RDGAAG(1053)) by mass spectrometry. Two ELISAs against…

A microarray analysis of full depth knee cartilage of ovariectomized rats

BACKGROUND:
This short communication focuses the on articular cartilage and the subchondral bone, both of which play important roles in the development of osteoarthritis (OA). There are indications that estrogen-deficiency, as the post-menopausal state, accelerate the development of OA.

Tummala SDiagnosis of Osteoarthritis by Cartilage Surface Smoothness Quantified Automatically from Knee MRI

OBJECTIVE:
We investigated whether surface smoothness of articular cartilage in the medial tibiofemoral compartment quantified from magnetic resonance imaging (MRI) could be appropriate as a diagnostic marker of osteoarthritis (OA).

METHOD:
At baseline, 159 community-based subjects aged 21 to 8…
