Transforming growth factor beta 1 positively regulates its own expression in normal and transformed cells.
Open accessAbstract
Transforming growth factor beta 1 (TGF-beta 1) regulates the growth, differentiation, or function of nearly all cell types. We now report that TGF-beta 1 increases steady-state levels of its own message in six different normal and transformed cells in culture. Accumulation of TGF-beta 1 mRNA can be detected by Northern blot analysis within 3 h of addition of the peptide to cells, and enhanced message levels persist as long as TGF-beta 1 is present in the culture medium. This autoinduction is half-maximal at approximately 10 PM TGF-beta 1, and maximal stimulation corresponds to a 2-3-fold increase in transcript levels. In normal rat kidney cells, the rise in TGF-beta 1 mRNA is actinomycin D-sensitive and is accompanied by a parallel (approximately 3-fold) increase in secretion of TGF-beta 1 protein in the culture medium of treated cells, as detected by immunoprecipitation of biosynthetically labeled 35S-labeled TGF-beta 1 using specific anti-TGF-beta 1 antibodies. Treatment of normal rat kidney cells with either epidermal growth factor or platelet-derived growth factor also results in an increase in TGF-beta 1 mRNA (2-3-fold), although epidermal growth factor and TGF-beta 1 appear to act via distinct mechanisms since their combined effects are greater than additive.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
