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

BM742401 is a tumor suppressor lncRNA downregulated in gastric cancer. As the promoter region and the entire transcript are embedded in a CpG island, we postulated that BM742401 is a tumor suppressor lncRNA inactivated by DNA methylation in chronic lymphocytic leukemia (CLL). The promoter of BM742401 was unmethylated in normal controls including three each of normal bone marrow, peripheral blood buffy coats, and CD19-sorted peripheral B-cells, but methylated in four (57.1%) CLL cell lines. Methylation of BM742401 correlated inversely with expression. In the completely methylated WAC3CD5+ CLL cells, 5-Aza-2'-deoxycytidine treatment led to promoter demethylation and re-expression of BM742401 transcript. Functionally, stable overexpression of BM742401 resulted in inhibition of cellular proliferation and enhanced apoptosis through caspase-9-dependent intrinsic but not caspase-8-dependent extrinsic apoptosis pathway, suggesting a tumor suppressor role of BM742401 in CLL. In primary CLL samples, methylation of BM742401 was detected in 43/98 (43.9%) of patients. Moreover, among CLL patients with standard-risk cytogenetic aberrations, methylation of BM742401 correlated with advanced Rai stage (≥ stage 2)(P = 0.002). Furthermore, BM742401 methylation was associated with miR-129-2 methylation (P = 0.05). BM742401 is a tumor suppressor lncRNA frequently methylated in CLL. The mechanism of BM742401 as a tumor suppressor warrants further studies.
