Activation of a serine/threonine kinase signaling pathway by transforming growth factor type beta.

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
Transforming growth factor type beta (TGF-beta) is a multifunctional factor that regulates proliferation and differentiation of many cell types. TGF-beta mediates its effects by binding to and activating cell surface receptors that possess serine/threonine kinase activity. However, the intracellular signaling pathways through which TGF-beta receptors act remain largely unknown. Here we show that TGF-beta activates a 78-kDa protein (p78) serine/threonine kinase as evidenced by an in-gel kinase assay. Ligand-induced activation of the kinase was near-maximal 5 min after TGF-beta addition to the cells and occurred exclusively on serine and threonine residues. This kinase is distinct from TGF-beta receptor type II, as well as several cytoplasmic serine/threonine kinases of similar size, including protein kinase C, Raf, mitogen-activated protein kinase kinase kinase, and ribosomal S6 kinase. Indeed, these kinases can be separated almost completely from p78 kinase by immunoprecipitation with specific antibodies. Furthermore, using different cell lines, we demonstrate that p78 kinase is activated only in cells for which TGF-beta can act as a growth inhibitory factor. These data raise the interesting possibility that protein serine/threonine kinases contribute to the intracellular relay of biological signals originating from receptor serine/threonine kinases such as the TGF-beta receptors.
