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

Frizzled homolog 1 (FZD1) is a transmembrane receptor that mediates Wnt signaling. The transcriptional regulation of FZD1 and the role of FZD1 in osteoblast biology are not well understood. We examined the role of E2F1 in FZD1 promoter activation and osteoblast differentiation and mineralization. A putative E2F1 binding site in the FZD1 promoter region was initially identified in silico and characterized further in Saos2 cells in vitro by chromatin immunoprecipitation (ChIP), electrophoretic mobility shift (EMSA) and promoter reporter assays. Over-expression of E2F1 transactivated the FZD1 promoter and increased endogenous FZD1 mRNA and protein levels in Saos2 cells. Over-expression of E2F1 in Saos2 cells up-regulated osteoblast differentiation markers alkaline phosphatase (ALP), type I collagen α (COL1A), and osteocalcin (OCN). Furthermore, E2F1 over-expression enhanced mineralization of differentiated Saos2 cells, whereas siRNA knockdown of FZD1 diminished the effects of E2F1 on osteoblast mineralization. The effects of E2F1 on FZD1 expression and osteoblast mineralization were further confirmed in normal human FOB osteoblasts. Taken together, our experiments demonstrate a role of E2F1 in osteoblast differentiation and mineralization and suggest that FZD1 is required, in part, for E2F1 regulation of osteoblast mineralization.
