Background and Aim: Pediatric patients with germline mutations in the phosphatase and tensin homolog (Pten) gene frequently develop aberrant adipose tissue growth called lipomas. In severe cases, recurrent lipoma formation can have adverse effects on organ function and quality of life. Due to the lack of understanding the basis of lipoma development, no systemic treatment options are available. We therefore aimed to characterize an already described lipoma bea...

Background: Bone development and remodeling are controlled by the phosphoinositid-3-kinase (PI3K) signaling pathway. We investigated the effects of downregulation of phosphatase and tensin homolog (Pten), a negative regulator of PI3K signaling, in osteoprogenitor cells.Methods: Femura, tibiae and bone marrow stromal cells (BMSCs) from mice with Cre-inducible Pten knockdown in cells expressing the transcription factor Ost...

PTEN downregulation in mouse osteoprogenitor cells impacts on bone stability and turnover

Lorenz Judith , Kirstein Anna , Nebe Michѐle , Richter Sandy , Le Duc Diana , Kiess Wieland , Kloting-Bluher Nora , Baschant Ulrike , Garten Antje ,

Background: Signaling through the phosphoinositid-3-kinase (PI3K) pathway modulates bone development and remodeling. We aimed to dissect the role of phosphatase and tensin homolog (Pten), a negative regulator of PI3K signaling, in osteoprogenitor cells.Methods: Femura, tibiae and bone marrow stromal cells (BMSCs) from mice with Cre-inducible Pten knockdown in cells expressing the transcription factor Osterix (Pten cKO) a...

Pten knockout in osteoprogenitor cells leads to loss of adipose tissue

Kolbig Florentien , Lorenz Judith , Roth Lisa , Lindhorst Andreas , Thor Doreen , Le Duc Diana , Gericke Martin , Kiess Wieland , Klöting Nora , Krause Kerstin , Garten Antje

Background and aim: Pediatric patients with germline mutations in phosphatase and tensin homolog (Pten) frequently develop aberrant adipose tissue growth/lipomas. In severe cases this can have adverse effects on organ function and quality of life. Due to the lack of understanding the basis of lipoma development, no systemic treatment options are available. We therefore aimed to characterize an already described lipoma bearing mouse model with conditio...
