Zusammenfassung
Drug and metabolite endocytosis, viral and bacterial infections, and transcitosis are facilitated by large GTPase dynamin. However, the underlying molecular mechanisms of dynamin action on homeostasis in hepatocytes without additional external signals (like growth factors, transferrin or drugs) are poorly understood. Therefore, we depleted hepatocytes of functional dynamin by adenoviral overexpression of a GTPase deficient dynamin mutant (DN-dynamin) for 48h and compared genome wide oligonucleotide microarrays, morphology and biochemical functions with AdLacZ infected controls. Blunting dynamin function leads to…
