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

Breast tumor metastasis is a leading cause of cancer-related deaths worldwide. Breast cancer (BC) cells frequently metastasize to the lungs, where they pose a formidable therapeutic challenge. In the current study, we evaluated the anti-proliferative and anti-metastatic effects of 2'-hydroxyflavanone (2HF) and RLIP inhibition in an array of triple-negative BC cell lines and an orthotopic mouse model of breast-to-lung metastasis. Compared to control treatment, RLIP inhibition reduced in-vitro cell viability and suppressed the migratory and invasive potential of BC cells. In-vitro studies showed that 2HF treatment reduced the expression of RLIP, KRAS, pERK, pSTAT3, and pP70S6K. Further, mice orthotopically implanted with lung-seeking luciferase-expressing TMD231 cells were treated with 2HF (50 mg/kg, b.w.), RLIP antisense (RAS; 5 mg/kg, b.w.), RLIP antibody (Rab; 5 mg/kg, b.w.) or a combination of 2HF + RAS + Rab. 2HF-, RAS-, and Rab-treated mice exhibited significantly lower primary tumor weight and reduced lung metastasis compared to control mice. Mice treated with a combination of 2HF + RAS + Rab exhibited no metastasis and significantly lower tumor weight than the single agent-treated mice. Collectively, our results suggest that 2HF has potential to be combined with RLIP inhibition/depletion to more effectively suppress primary breast tumor growth and metastasis to the lungs.
