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

High-density lipoprotein receptors scavenger receptor class B type I [HDLR-SR-B1 (SR-B1)] is a key player in reverse cholesterol transport and maintaining blood cholesterol. We demonstrated that human SR-B1 is transcriptionally activated by 17β-estradiol (E2) in HEPG2 and JAR cells. SR-B1 promoter contains multiple estrogen response elements (ERE half-sites) along with some Sp1 binding sites. Knockdown of estrogen receptor (ER)α and ERβ down-regulated E2-induced SR-B1 expression. ERs were bound to SR-B1 promoter EREs in an E2-dependent manner. Along with ERs, mixed-lineage leukemia (MLL) histone methylases, especially MLL1 and MLL2, play key roles in E2-mediated SR-B1 activation. MLL1 and MLL2 bind to SR-B1 promoter in an E2-dependent manner and control the assembly of transcription pre-initiation complex and RNA polymerase II (RNAPII) recruitment. ERs and MLLs play critical roles in determining the cholesterol uptake by steroidogenic tissues/cells, and their knockdown suppressed the E2-induced cholesterol uptake efficiencies of the cells. Intriguingly, MLL2 knockdown in mice resulted in a 33% increase in plasma cholesterol level and also reduced SR-B1 expression in mice liver, demonstrating its crucial functions in controlling plasma cholesterol in vivo.
