Adrenomedullin (AM) is a hypotensive polypeptide that has been shown to stimulate cyclic AMP and intracellular free Ca2+ agents that are known to induce expression of proto-oncogenes, in various cell types. Transforming growth factor-beta 1 (TGF-beta1) is a multifunctional polypeptide that regulates proliferation, differentiation and cell cycle progression(More)
Transforming growth factor-beta (TGFbeta) and adrenomedullin (AM) are multifunctional regulatory peptides that are secreted by a variety of normal and malignant cells. The TGFbetas are expressed in developing organs and adults, and their tissue distribution pattern has possible significance for signaling roles in many epithelial-mesenchymal interactions. AM(More)
The transforming growth factor-betas (TGF-beta s) are multifunctional proteins that inhibit the proliferation of many epithelial cells through a set of cell protein receptors that includes the TGF-beta type I (RI) and type II (RII) receptors. Loss of growth inhibition by TGF-beta is thought to contribute to the development of many types of tumors. In the(More)
The transforming growth factor-betas (TGF-betas) are multifunctional regulatory polypeptides that play a crucial role in many cell processes and function through a set of cell surface protein receptors that includes TGF-beta type I (RI) and type II (RII). The present study reports a comprehensive comparison of the patterns of expression of TGF-beta RI and(More)
We developed the AJBL6 transforming growth factor-beta 1 (TGF-beta1) heterozygous (HT) mouse by mating A/J mice with C57BL/6 TGF-beta1 HT mice that shows increased carcinogen-induced lung lesions with decreased latency to examine progressive events in lung tumorigenesis. Mouse cDNA macroarrays were used to identify cell cycle genes that are differentially(More)
OBJECTIVE The aim of this study was to investigate the relationship between the expression of the TGF-beta ligands and TGF-beta receptors to the expression of p27(Kip1), a TGF-beta-regulated gene, in endocervical cancer. METHODS To examine the expression of TGF-beta and p27(Kip1) in malignant transformation of the uterine endocervix, a panel of 23(More)
Pulmonary hypoplasia has been found in the human neonatal autopsy population and has been attributed to an alteration in epithelial-mesenchymal interactions during development of the lung. Pulmonary acinar aplasia is a very rare and severe form of pulmonary hypoplasia. The transforming growth factor-betas (TGF-β) are multifunctional regulatory peptides that(More)
