Methods for treatment of obesity, atherosclerosis, and thrombosis
Methods for treating obesity, atherosclerosis, and/or thrombosis comprise reducing an expression level or activity of thymidine phosphorylase in a subject in need thereof. Reducing the expression level or activity of thymidine phosphorylase as part of a method for treatment of obesity, atherosclerosis, and/or thrombosis can comprise administering to the subject an effective amount of a thymidine phosphorylase inhibitor. The thymidine phosphorylase inhibitor administered to the subject can be tipiracil, which can be administered alone or in combination with other therapeutic agents, including tissue plasminogen activator and aspirin.
1 . A method of treating obesity, comprising administering to a subject in need thereof an effective amount of a thymidine phosphorylase inhibitor sufficient to directly inhibit and reduce an activity of thymidine phosphorylase in the subject, wherein the thymidine phosphorylase inhibitor is tipiracil.
2 . The method of claim 1 , wherein administering the thymidine phosphorylase inhibitor reduces an expression level of lipogenesis markers.
3 . The method of claim 2 , wherein the lipogenesis markers are selected from the group consisting of acetyl co-A carboxylase, peroxisome proliferator-activated receptor gamma, and a combination thereof.
4 . The method of claim 1 , wherein administering the thymidine phosphorylase inhibitor reduces an expression level or activity of a mitogen activated protein kinase (MAPK).
5 . The method of claim 4 , wherein the mitogen activated protein kinase is selected from the group consisting of p38, ERK1/2, and JNK2.
6 . The method of claim 1 , wherein administering the thymidine phosphorylase inhibitor increases an expression level of a lipolysis protein, an adipose triglyceride lipase, or combinations thereof.
7 . The method of claim 1 , wherein administering the thymidine phosphorylase inhibitor reduces an activity level of NF-κB.
8 . The method of claim 1 , wherein administering the thymidine phosphorylase inhibitor reduces an expression level of an inflammatory cytokine.
9 . The method of claim 8 , wherein the inflammatory cytokine is selected from the group consisting of TNFα, IL-1, IL-6, IL-8, IL-17, interferon-γ, granulocyte-colony stimulating factor, Toll-like receptor, and combinations thereof.
10 . The method of claim 1 , wherein administering the thymidine phosphorylase inhibitor reduces an expression level or activity of a glycolysis-associated protein.
11 . The method of claim 10 , wherein the glycolysis-associated protein is selected from fructosebisphosphate aldolase (FBPA), glyceraldehyde-3-phosphate dehydrogenase (GAPDH), and pyruvate kinase muscle isoform M2 (PKM2).
12 . The method of claim 1 , wherein administering the thymidine phosphorylase inhibitor increases an amount of glucose tolerance in the subject.
13 . The method of claim 1 , wherein administering the thymidine phosphorylase inhibitor decreases body weight of the subject, reduces lipid accumulation in a liver of the subject, and/or reduces an amount of atherosclerotic plaques in one or more blood vessels of the subject.
14 . The method of claim 1 , wherein the subject is a male subject.
