摘要:
Provided herein are methods and compositions relating to sirtuin modulation of Wnt pathway signaling, including the use of sirtuin and sirtuin-modulating agents in the prevention and treatment of cancer and other diseases.
摘要:
The present invention provides new and advantageous methods, compositions, cell constructs and animal models related to inhibiting the senescence of vertebrate cells and vertebrate organisms based on the use of SIRT1 polynucleotides and polypeptides, as well as mutant SIRT1 polynucleotides and polypeptides. The invention provides polynucleotides that encode variants and fragments of SIRT1 polypeptides, and also provides variant SIRT1 polypeptides and fragments thereof. Additionally the invention provides a method of inhibiting or delaying the expression in a vertebrate cell of a protein having biological activity associated with loss of population doubling in the cell. The invention further provides a method of treating a pathology, a disease or a medical condition in a subject, wherein the pathology responds to an SIRT1 polypeptide. The invention also provides a vertebrate cell that incorporates a heterologous nucleic acid encoding a variant of SIRT1, or a fragment thereof, as well as a transgenic mammal a majority of whose cells harbor a transgene including a nucleic acid sequence encoding an SIRT1 polypeptide. The invention also provides an antibody that binds immunospecifically to a variant SIRT1 polypeptide or a fragment thereof, and a method of determining whether the amount of an SIRT1 polypeptide in a sample differs from the amount of the SIRT1 polypeptide in a reference. The invention further provides a method of contributing to the diagnosis or prognosis of, or to developing a therapeutic strategy for, a disease or pathology in a subject, wherein the disease or pathology responds to treatment with an SIRT1 polypeptide and wherein the amount of SIRT1 polypeptide in the pathology is known to differ from the amount of the SIRT1 polypeptide in a nonpathological state.
摘要:
Personalized, health and performance programs are generated for individuals based on various biomarkers and performance and lifestyle assessments. In one embodiment, a diagnostic test of blood or other biological specimen(s) is used to determine key biological marker levels. Information and assessments of the user's physical performance, life style and health and wellness goals is also collected and provided to an expert system that matches the biomarker levels and assessments to a knowledgebase of scientific knowledge about biomarker levels and health and fitness outcomes. Personal recommendations and advice on nutrition and exercise is then generated, which may be used to help individuals reach their diet, fitness, and wellness goals and improve their physical and mental performance and well being in measurable ways.
