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

Triple receptor-negative breast cancers (TNBCs) generally have poor prognoses because of the loss of therapeutic targets. As lysophosphatidic acid (LPA) receptor signaling has been shown to affect breast cancer initiation and progression, we try to evaluate the potential roles of LPA receptors in TNBCs. We examined mRNA and protein expressions of LPA receptors 1-3, using quantitative real-time PCR and immunohistochemical analyses in normal (n = 37), benign disease (n = 55), and breast cancer tissues (n = 82). Carcinomas expressed higher levels of LPA2 and LPA3 mRNAs (0.17 ± 0.070 and 0.05 ± 0.023, respectively) than did normal breast tissue (0.13 ± 0.072 and 0.02 ± 0.002, respectively). Enhanced immunohistochemical staining for LPA2 and LPA3 protein was also consistently observed in carcinomas. The LPA3 overexpression was associated with lymph node metastases, and absence of estrogen receptor, progesterone receptors, and human epidermal growth factor receptor 2 expression. TNBC tissues and cell lines showed the highest LPA3 expression compared with luminal-type A and B breast cancers. Suppression of LPA3 by shRNA did not influence cell growth in breast cancer cells. However, the migration and invasion of TNBC cells were significantly inhibited by LPA3-shRNA or inhibitor, which had no or less effect on normal and non-TNBC breast cells. In conclusion, our data indicated that the expression of LPA receptor 3 was increased in human TNBCs and is associated with tumor metastatic ability, and this implies that LPA3 is a potential therapeutic target for the treatment of TNBCs.
