The Impact of Vitamin K2 on Energy Metabolism

Environmental and behavioral adaptations introduced during the last decades have synergistically enhanced man’s lifespan, but also paved the ground for disease states involving impairment of multiple organs, which are both modulating and depending on homeostatic calorie “accounting.

Vitamin K2 Facilitating Inter-Organ Cross-Talk

This chapter features how vitamin K2 is instrumental in bringing about inter-organ communication, thus facilitating (a) a synthesis/secretion of the endocrine, humoral factors from various organs and (b) physiological responses to the said factors by a multitude of organ systems of the body, thus creating a ‘lattice’ of reciprocal regulatory loops in order to ensure endocrine homeostasis

Vaccination of patients with cutaneous melanoma with telomerase-specific peptides

Purpose: A phase I study was conducted to investigate the safety, tolerability, and immunological responses to vaccination with a combination of telomerase-derived peptides GV1001 (hTERT: 611-626) and p540 (hTERT: 540-548) using granulocyte-macrophage colony-stimulating factor (GM-CSF) or tuberculin as adjuvant in patients with cutaneous melanoma. Experimental design: Ten patients with melanoma stages UICC IIb-IV were vaccinated 8times intradermally with either 60 or 300nmole of GV1001 and p540 peptide using GM-CSF as adjuvant. A second group of patients received only 300nmole GV1001 in combination with tuberculin PPD23 injections. HLA typing was not used as an inclusion criterion. Peptide-specific immune responses were measured by delayed-type hypersensitivity (DTH) reactions, in vitro T cell proliferation assays, and cytotoxicity (51-Chromium release) assays for a selected number of clones subsequently generated. Results: Vaccination was well tolerated in all patients. Peptide-specific immune response measured by DTH reactions and in vitro response could be induced in a dose-dependent fashion in 7 of 10 patients. Cloned T cells from the vaccinated patients showed proliferative responses against both vaccine peptides GV1001 and p540. Furthermore, T cell clones were able to specifically lyse p540-pulsed T2 target cells and various pulsed and unpulsed tumor cell lines. Conclusion: These results demonstrate that immunity to hTERT can be generated safely and effectively in patients with advanced melanoma and therefore encourage further trial
