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

Cartilage degeneration in the course of osteoarthritis (OA) is associated with an alteration in chondrocyte metabolism. In order to identify molecules representing putative key regulators for diagnosis and therapeutic intervention, we analyzed gene expression and microRNA (miR) levels in OA and normal knee cartilage using a customized cartilage cDNA array and quantitative RT-PCR. Among newly identified candidate molecules, H19, IGF2, and ITM2A were significantly elevated in OA compared to normal cartilage. H19 is an imprinted maternally expressed gene influencing IGF2 expression, whose transcript is a long noncoding (lnc) RNA of unknown biological function harboring the miR-675. H19 and IGF2 mRNA levels did not correlate significantly within cartilage samples suggesting that deregulation by imprinting effects are unlikely. A significant correlation was, however, observed for H19, COL2A1, and miR-675 expression levels in OA tissue, and functional regulation of these candidate molecules was assessed under anabolic and catabolic conditions. Culture of chondrocytes under hypoxic signaling showed co-upregulation of H19, COL2A1, and miRNA-675 levels in close correlation. Proinflammatory cytokines IL-1β and TNF-α downregulated COL2A1, H19, and miR-675 significantly without close statistical correlation. In conclusion, this is the first report demonstrating deregulation of an lncRNA and its encoded miR in the context of OA-affected cartilage. Stress-induced regulation of H19 expression by hypoxic signaling and inflammation suggests that lncRNA H19 acts as a metabolic correlate in cartilage and cultured chondrocytes, while the miR-675 may indirectly influence COL2A1 levels. H19 may not only be an attractive marker for cell anabolism but also a potential target to stimulate cartilage recovery.
