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

Secreted protein acidic and rich in cysteine (SPARC) is a matricellular protein highly expressed in bone tissue that acts as a chemoattractant factor promoting the arrival of prostate cancer (PCa) cells to the bone marrow. However, the contribution of SPARC during the early stages of tumor progression remains unclear. In this study, we show that SPARC is highly expressed in PCa tissues with a higher Gleason score. Through stable knockdown and overexpression of SPARC in PC3 and LNCaP cells, respectively, here we demonstrate that endogenous SPARC induces the epithelial-mesenchymal transition (EMT), decreasing E-cadherin and cytokeratin 18 and increasing N-cadherin and vimentin. Moreover, SPARC induces the expression of EMT regulatory transcription factors Snail family transcriptional repressor 1 (Snail), Snail family transcriptional repressor 2 (Slug), and zinc finger E-box binding homeobox 1 (Zeb1). In addition, SPARC knockdown in PC3 cells decreases migration and invasion in vitro, without modifying cell proliferation. Our results indicate that SPARC might facilitate tumor progression by modifying the cellular phenotype in cancer cells.
