High glucose upregulates BMAL1 in chondrocytes from macroscopically normal and osteoarthritic human cartilage but this only results in increased collagen synthesis in chondrocytes from macroscopically normal cartilage regions.

1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Objective: Osteoarthritic (OA) chondrocytes exhibit limited capacity for new collagen synthesis. High glucose promotes collagen I and III production by fibroblasts. The purpose of this study was to determine if it also promotes collagen II (COL2) synthesis by chondrocytes. Design: Chondrocytes isolated from osteoarthritic (OA) and macroscopically normal (MN) cartilage from patients with knee OA were maintained in 1 % oxygen in 4 mM or 10 mM glucose for up to 24 h. Results: Secreted COL2 levels were higher in MN but not OA chondrocytes maintained in 10 mM versus 4 mM glucose with increased COL2 production specifically evident in the first 6 h of high glucose exposure. Conclusions: These data demonstrate a novel mechanism by which high glucose-mediated upregulation of BMAL1 promotes collagen synthesis in chondrocytes. Although high glucose leads to similar upregulation of BMAL1 and P4HA2 in both MN and OA chondrocytes, overall lower
