pubmed-article:1345368 | pubmed:abstractText | The effects of the active gastrin fragments, penta- and tetragastrin on the incorporation of tritiated thymidine into the rat pituitary tumoral cells were investigated in vitro. The significant stimulation of 3H-thymidine incorporation was observed as an effect of the investigated substances. The putative role of gastrin as an autocrine growth factor active in pituitary tumorigenesis was discussed. | lld:pubmed |
