Impaired leptin activity in New Zealand Obese mice: model of angiogenesis.

Leptin is prompt to drive angiogenesis, effecting proper vascularisation. Tissue remodeling (including adipose organ) is associated with the angiogenic response. The aim of this study was to investigate the effect of hyperleptinemia on angiogenesis in subcutaneous (s.

DYRK1 is a co-activator of FKHR (FOXO1a)-dependent glucose-6-phosphatase gene expression.

Expression of glucose-6-phosphatase (G6Pase), one of the rate-limiting enzymes of hepatic gluconeogenesis, has recently been shown to be transactivated by the transcription factor FKHR. One of the proteins known to directly interact with FKHR is the nuclear protein kinase DYRK1A. In order to study the effects of DYRK1A on G6Pase gene expression, we generated a H4IIEC3 rat hepatoma cell line stably expressing DYRK1A by retroviral infection.
