Functional identification of a BAC clone from 16q24 carrying a senescence gene SEN16 for breast cancer cells.

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
We have identified an 85 kb BAC clone, 346J21, that carries a cell senescence gene (SEN16), previously mapped to 16q24.3. Transfer and retention of 346J21 in breast cancer cell lines leads to growth arrest after 8-10 cell doublings, accompanied by the appearance of characteristic senescent cell morphology and senescence-associated acid beta-galactosidase activity. Loss of transferred BAC results in reversion to the immortal growth phenotype of the parental cancer cell lines. BAC 346J21 restores senescence in the human breast cancer cell lines, MCF.7 and MDA-MB468, and the rat mammary tumor cell line LA7, but not in the human glioblastoma cell line T98G. We postulate that inactivation of both copies of SEN16 is required for the immortalization of breast epithelial cells at an early stage of tumorigenesis. Positional mapping of 346J21 shows that SEN16 is distinct from other candidate tumor suppressor genes reported at 16q24.
