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

aimsThe present study aimed to examine the roles of circRNA-circSMAD2 and its regulatory mechanisms in endometriosis (EMs).

backgroundEvidence has confirmed that circRNAs play multiple roles in regulating the occurrence and development of EMs, but the regulatory mechanisms of circRNAs in EMs remain largely unknown.

objectivesThe roles and regulatory mechanisms of circSMAD2 in EMs.

methodsEutopic and ectopic endometrium of ovarian EMs as well as normal endometrial tissues, were used to extract circRNA, mRNA, and total proteins. The human endometrial stromal cell lines (ThESCs) and endometrial stromal cells (ESCs) were stimulated with different concentrations or times of 17β-estradiol (E2). The mouse model of EMs was established by implanting uterine horns onto the peritoneum wall using a suture.

resultsCompared with normal tissues, the expression of circSMAD2 was significantly decreased in eutopic and ectopic endometrial tissues. Furthermore, the expression of circSMAD2 was downregulated by E2 in a dose- and time-dependent manner in ThESCs and ESCs. Overexpression of circSMAD2 inhibited the invasion and migration of ThESCs, while knockdown of circSMAD2 exerted the opposite effect. The RNA binding protein quaking (QKI), which is involved in circRNA formation, was lower in eutopic and ectopic endometrial tissues compared to normal tissues. Moreover, E2 suppressed the expression of circSMAD2 by inhibiting the expression of QKI. Additionally, E2 enabled the expression of estrogen receptor beta (ERβ) to inhibit the expression of QKI and circSMAD2 in vitro and in vivo.

conclusionThe E2/ERβ/QKI/circSMAD2 pathway was involved in cellular migration and invasion in EMs.
