|BMP-7-induced cell cycle arrest of anaplastic thyroid carcinoma cells via p21(CIP1) and p27(KIP1).|
|PMID: 11453659 Owner: NLM Status: MEDLINE|
|The aim of the present study was to investigate the effect of bone morphogenetic protein (BMP-7) on thyroid carcinoma cell growth. Addition of BMP-7 inhibited the proliferation of four out of six human anaplastic thyroid carcinoma cell lines, observed as decreased incorporation of (3)H-thymidine and decreased cell number. The growth inhibitory effect was cell density-dependent; sparse cells were inhibited by BMP-7 whereas dense cells were not. Cell cycle analysis by flow cytometry showed an increased fraction of cells in the G1-phase and subsequent decrease in both S- and G2/M-phase after BMP-7 stimulation. Furthermore, BMP-7 caused an upregulation of the cyclin-dependent kinase inhibitors (CDKIs) p21 and p27, decreased activity of Cdk2 and Cdk6, and hypophosphorylation of the retinoblastoma protein (pRb). These findings suggest a growth inhibitory effect of BMP-7 on anaplastic thyroid carcinoma cells by inhibition of Cdk activity shifting the Rb protein to the hypophosphorylated state.|
