Uncarboxylated osteocalcin, allegedly via G-protein coupled receptors, interacts with adipocytes and pancreatic β-cells, thus affecting metabolic homeostasis. Here, we demonstrate that MK-7 directly and indirectly, via osteocalcin, modulates the endocrine functions of both β-cells and adipocytes.• It was shown (by applying the Mir@nt@n-based emulation algorithm) that MK-7 was involved in a network of intracellular regulat...

Epidemiological studies suggest that patients using proton pump inhibitors (PPIs) have increased fracture risk. We have previously shown that H+/K+ATPase beta-subunit knockout (KO) mice have reduced BMD, BMC and mechanical bone strength compared to WT. Like users of PPIs, these mice have elevated serum gastrin levels due to high gastric pH. We wanted to study whether elevated gastrin influences bone quality in these mice.Female KO and WT mice aged 6 week...
