Leptin is mainly synthesized and secreted by fat cells in proportion to adipose tissue mass. Under physiological conditions, this hormone reduces food intake and increases thermogenesis through interactions with neurons in the central nervous system. However, transport of leptin into the central nervous system via the blood-brain barrier is saturable, and(More)
Chromogranin A (CGA) is a major secretory protein present in the soluble matrix of chromaffin granules of neuroendocrine cells and tumours, such as phaeochromocytomas. CGA has several functions, some of which may be involved in the distinct phenotypic differences of phaeochromocytomas in patients with von Hippel-Lindau (VHL) syndrome compared to multiple(More)
F1FoATP synthase (ATP synthase) is a ubiquitous enzyme complex in eukaryotes. In general it is localized to the mitochondrial inner membrane and serves as the last step in the mitochondrial oxidative phosphorylation of ADP to ATP, utilizing a proton gradient across the inner mitochondrial membrane built by the complexes of the electron transfer chain.(More)
The incidence of obesity in the Western world has increased dramatically during the recent decades. Epidemiological data suggest that obesity is associated with an increased risk of several but not all types of cancers, with clear sex-specific differences. The underlying mechanisms are still a matter of debate. In this review, we discuss the potential(More)
