Tip30 controls differentiation of murine mammary luminal progenitor to estrogen receptor-positive luminal cell through regulating FoxA1 expression.
Article in Cell death & disease, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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.
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
Estrogen receptor-alpha positive (ER(+)) breast cancers comprise the majority of human breast cancers, but molecular mechanisms underlying this subtype of breast cancers remain poorly understood. Here, we show that ER(+) mammary luminal tumors arising in Tip30(-/-)MMTV-Neu mice exhibited increased enrichment of luminal progenitor gene signature. Deletion of the Tip30 gene increased proportion of mammary stem and progenitor cell populations, and raised susceptibility to ER(+) mammary luminal tumors in female Balb/c mice. Moreover, Tip30(-/-) luminal progenitors displayed increases in propensity to differentiate to mature ER(+) luminal cells and FoxA1 expression. Knockdown of FoxA1 expression in Tip30(-/-) progenitors by shRNA specific for FoxA1 reduced their differentiation toward ER(+) mature luminal cells. Taken together, our results suggest that TIP30 is a key regulator for maintaining ER(+) and ER(-)luminal pools in the mammary luminal lineage, and loss of it promotes expansion of ER(+) luminal progenitors and mature cells and ER(+) mammary tumorigenesis.
