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

Inactivation and silencing of PTEN have been observed in multiple cancers, including follicular thyroid carcinoma. PTEN (phosphatase and tensin homologue deleted from chromosome 10) functions as a tumour suppressor by opposing the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) signalling pathway. Despite correlative data, how deregulated PTEN signalling leads to thyroid carcinogenesis is not known. Mice harbouring a dominant-negative mutant thyroid hormone receptor beta (TRbeta(PV/PV) mice) spontaneously develop follicular thyroid carcinoma and distant metastases similar to human cancer. To elucidate the role of PTEN in thyroid carcinogenesis, we generated TRbeta(PV/PV) mice haploinsufficient for Pten (TRbeta(PV/PV)Pten(+/-) mouse). PTEN deficiency accelerated the progression of thyroid tumour and increased the occurrence of metastasis spread to the lung in TRbeta(PV/PV)Pten(+/-) mice, thereby significantly reducing their survival as compared with TRbeta(PV/PV)Pten(+/+) mice. AKT activation was further increased by two-fold in TRbeta(PV/PV)Pten(+/-) mice thyroids, leading to increased activity of the downstream mammalian target of rapamycin (mTOR)-p70S6K signalling and decreased activity of the forkhead family member FOXO3a. Consistently, cyclin D1 expression was increased. Apoptosis was decreased as indicated by increased expression of nuclear factor-kappaB (NF-kappaB) and decreased caspase-3 activity in the thyroids of TRbeta(PV/PV)Pten(+/-) mice. Our results indicate that PTEN deficiency resulted in increased cell proliferation and survival in the thyroids of TRbeta(PV/PV)Pten(+/-) mice. Altogether, our study provides direct evidence to indicate that in vivo, PTEN is a critical regulator in the follicular thyroid cancer progression and invasiveness.
