The present disclosure is directed to, among other things, methods and uses for treating anhedonia in a subject, such as a human, wherein the methods comprise administering a therapeutically effective amount of N-[4-(6-fluoro-3,4-dihydro-1H-isoquinolin-2-yl)-2,6-dimethylphenyl]-3,3-dimethylbutanamide (Compound A) to the subject in need thereof, and the uses comprise Compound A for use in treating anhedonia in a subject, such as a human. The present disclosure is further directed to various improved methods of therapy and administration of Compound A.

Methods and uses for treating anhedonia

The invention features ABC1 nucleic acids and polypeptides for the diagnosis and treatment of abnormal cholesterol regulation. The invention also features methods for identifying compounds for modulating cholesterol levels in an animal (e.g., a human).

Methods and compounds are disclosed for lowering serum LDL levels or serum cholesterol levels, or for reducing the transport of cholesterol from the gut to the blood or the lymph, based on the observation that a gene known as ABC1 is necessary in order for cholesterol to be transported from the intestinal lumen into the bloodstream. A mutant chicken phenotype, known as the WHAM chicken, characterized by low levels of serum LDL and reduced transport of cholesterol, facilitated the discovery of this function of the ABC1 gene. Techniques which act to inhibit ABC1 activity in the cells of the intestinal wall will result in lower serum cholesterol.
