摘要:
Circulating uncarboxylated matrix Gla-protein (ucMGP), in particular desphospho-ucMGP, is provided as a prognostic biomarker for allograft failure and mortality in patients who received organ transplantation and who are under immunosuppressive medication. A diagnostic tool is provided to monitor vitamin K status in such patients, i.e. the level of uncarboxylated species of extra-hepatic vitamin K-dependent proteins. Various forms and recommended dosages of vitamin K, optionally combined with vitamin D and/or other immunosuppressive medication, are provided to optimize the treatment of such patients resulting in decreased allograft failure and improved patient survival.

摘要:
Vitamin K is effective in counteracting cardiovascular disorders such as the reduction in arterial elasticity normally associated with the aging process. A pharmaceutical composition or nutritional formulation comprising vitamin K can be used to combat age-related stiffening of the arteries, and the consequences thereof, namely pulmonary congestion, hypertension, left ventricular hypertrophy, congestive (right sided) heart failure, left sided or left ventricular failure, chronic cardiac failure, angina pectoris, myocardial infarction, Mönckeberg's sclerosis and stroke. In various embodiments, vitamin K can also be used to reduce or reverse calcification of a blood vessel in pre-existing cardiovascular disorders such as arteriosclerosis.
摘要:
The present invention includes a diagnostic assay for the detection and determination of MGP in a human serum sample, which comprises the use of one or more antibodies, preferably monoclonal antibodies, specifically recognizing epitopes on and/or conformations of human Matrix Gla-Protein. A method is provided for using MGP-related antigens as biomarkers for certain diseases, for example, atherosclerosis and other vascular diseases, and angiogenesis/neogenesis in tumor development. Monoclonal antibodies of class IgG are described for use in the assay, which are defined herein as mAb3-15, mAb35-49[Glu], mAb35-49[Gla], mAb35-53[Glu], and mAb35-53[Gla]. Polyclonal antibodies and methods are also disclosed for measuring MGP in a human serum sample.
摘要:
A non-toxic biologically active compound is provided having the following general formula (I), wherein n is an integer from 1 to 14, preferably from 2 to 4, and R is an organic moiety, preferably a group different from but structurally substantially similar to 2-methyl naphthoquinone, or a group P-C(R1)-P, where each P stands for a -PO(OH)2 group and R1 is a (poly)isoprenyl group, hydroxy, halogen (preferably chloro or bromo), or hydrogen, or a pharmaceutically acceptable derivative thereof. These compounds are useful for the treatment or prevention of certain disorders in a mammal, especially a human being, for example postmenopausal loss of bone in women, juvenile or senile osteoporosis in men and women, cardiovascular calcification and other ectopic calcifications.
摘要:
A new indication of vitamin K is disclosed which results in the provision of methods of treatment, both therapeutic and non-therapeutic, as well as functional foods and pharmaceutical and nutraceutical products comprising vitamin K for improving microvascular integrity and capillary structure and function, thus preventing, mitigating, counteracting or curing diseases associated with impaired capillary morphology including the glycocalyx or capillary dysfunction. Preferably, vitamin K is a menaquinone, most preferably selected from the long-chain menaquinones MK-7 through MK-10.
摘要:
The present invention provides methods and compositions for treating or preventing skin cancer, in particular melanoma, parakeratosis, improving the skin integrity, the skin barrier function and/or decreasing skin ageing in a mammalian subject, preferably a human subject, the method comprising applying vitamin K1, vitamin K2, Matrix Gla-Protein (MGP) or at least one bioactive peptide derived from MGP in an effective amount to the skin. Preferably, the vitamin K comprises at least one of the long-chain menaquinones MK-7 through MK-10. Preferably, the MGP-derived peptides contain the uncarboxylated Gla-domain of human MGP.
摘要:
The use of vitamin K is provided in preparing pharmaceutical or nutraceutical products for counteracting an increased thrombosis risk caused by poor vitamin K status. The most likely mechanism underlying the vitamin K-insufficiency-induced thrombosis risk is undercarboxylation of vascular protein S. Preferably, vitamin K is a menaquinone, most preferably selected from the long-chain menaquinones MK-7 through MK-10.
