Magnetic resonance spectroscopy (MRS) is a powerful tool when studying metabolism in intact and living organs preserving cells in their natural microenvironment with minimal external interference. The unique insights offered by the observation of metabolic ...
Ovarian hormones increase breast cancer risk by poorly understood mechanisms. We assess the role of progesterone on global stem cell function by serially transplanting mouse mammary epithelia. Progesterone receptor (PR) deletion severely reduces the regene ...
In pulmonary arterial hypertension, plexiform lesions are associated with severe arterial obstruction and right ventricular failure. Exploring their structure and position is crucial for understanding the interplay between hemodynamics and vascular remodel ...
Zaragozic acids (or squalestatins) are very potent inhibitors of squalene synthase. They or simpler analogs have potential as drugs for lowering the endogenous level of cholesterol in human serum. These compounds are Ras farnesyltransferase inhibitors and ...
Cognitive difficulties are the most common neurological complications in neurofibromatosis type 1 (NF1) patients. Recent animal models proposed increased GABA-mediated inhibition as one underlying mechanism directly affecting the induction of long-term pot ...
Melanoma is one of the most aggressive cancers, and its incidence is increasing. These tumors derive from the melanocyte lineage and remain incurable after metastasis. Here we report that SONIC HEDGEHOG (SHH)-GLI signaling is active in the matrix of human ...
The incidence of melanoma has significantly increased and a better understanding its pathogenesis and development of new therapeutic strategies are urgently needed. Here we describe a murine model of metastatic cutaneous melanoma using C57BL/6 mice express ...
