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

CYP27A1, an enzyme involved in regulating cellular cholesterol homeostasis, converts cholesterol into 27-hydroxycholesterol (27-HC). The relationship between CYP27A1 and cell proliferation was studied to determine the role of CYP27A1 in bladder cancer. The expression of CYP27A1 in three bladder cancer cell lines (T24, UM-UC-3 and 5637) were assessed by qRT-PCR and Western blotting, and cells with stable CYP27A1 expression were generated by lentiviral infection. Cell proliferation was detected by MTT assays, colony formation assays and a tumor xenograft model in vitro and in vivo, and the intracellular 27-HC and cholesterol secretion levels were detected by enzyme-linked immunosorbent assays (ELISA). The results revealed that CYP27A1 expression was downregulated in androgen receptor (AR)-positive T24/UM-UC-3 cells compared with AR-negative 5637 cell. After CYP27A1 expression was restored, cell proliferation was inhibited in vitro and in vivo because much more intracellular 27-HC was produced in the CYP27A1-overexpressing cells than in the control cells. Both T24 and UM-UC-3 cells treated with 27-HC showed similar results. In addition, CYP27A1/27HC could reduce the cellular cholesterol level in both T24 and UM-UC-3 cells by upregulating ATP-binding cassette transporters G1 and A1 (ABCG1 and ABCA1) through Liver X receptors (LXRs) pathway and downregulating low-density lipoprotein receptor (LDLR) expression. These findings all suggest that CYP27A1 is a critical cholesterol sensor in bladder cancer cells that may contribute significantly to bladder cancer proliferation.
