We have studied the functional repercussions of cerebrovascular abnormalities in transgenic mice overexpressing TGF-beta1. These mice develop Alzheimer's disease-like vascular and meningeal alterations without parenchymal degeneration. Autoradiographic cerebral blood flow measurements in 9-month-old TGF-beta1 mice compared to non-transgenic littermates(More)
We examined the topology of angiotensin-converting enzyme (ACE) mRNA expression, activity, and shedding in myocardial infarction-induced heart failure and sought to elucidate the source of the increased plasma ACE activity in this model. Three months after coronary ligature, lung, scar, and remaining viable left ventricular tissues were analyzed for ACE(More)
Experiments with primary cultures of isolated porcine thyroid follicles were performed in serum-free well-defined medium to investigate different pathways that may be involved in the regulation of thyroid cell growth. The incorporation of [3H]thymidine into DNA within 72 h was about 25-fold with fetal calf serum (FCS, 1%), 20-fold with epidermal growth(More)
One of the main problems in establishing isolated thyroid follicles in vitro is their tendency to form inside-out follicles. The reason for this change in polarity is unknown. We describe here a method for the preparation of stable thyroid follicles with preserved polarity for at least 6 days. Isolated follicles were obtained by infusion of collagenase (1.5(More)
