Abstract: The present disclosure provides methods and compositions for transferring a gene encoding sphingosine-1-phosphate lyase (SPL) in a subject in need thereof by using recombinant AAV virions. The subject may have or may develop SPL insufficiency syndrome (SPLIS). The subject may be identified on the basis of a genetic test and/or SPLIS symptoms. The methods and compositions are also useful in lowering circulating sphingosine-1-phosphate levels in a subject having elevated S1P levels.

Abstract: The present invention is directed to unsaturated sphingosine compounds which are useful as therapeutic agents for the treatment of cancer and for the treatment of other diseases including diabetes and infection with intracellular bacteria. The invention is also directed to methods of using the compounds and pharmaceutical compositions comprising the compounds in treating these diseases.

Abstract: Compositions and methods for modulating immune function are provided based on the unexpected discovery that inhibition of sphingosine-1-phosphate lyase (SPL) activity confers useful immunosuppressive effects, for example to modulate immune function in treatment or prevention of inflammation, transplant graft rejection, autoimmune disease, allergy, or other conditions, including therapeutic alteration of immune system cell survival and/or proliferation. Altering SPL activity by direct or indirect pharmacological intervention, or alternatively by molecular genetic methods to alter SPL expression levels, are also contemplated.

Abstract: Compositions, methods and kits for diagnosing and treating cancer are provided. Therapeutic compositions may comprise agents that modulate the expression or activity of a sphingosine-1-phosphate lyase (SPL). Such compositions may be administered to a mammal afflicted with cancer. Diagnostic methods and kits may employ an agent suitable for detecting alterations in endogenous SPL. Such methods and kits may be used to detect the presence of a cancer or to evaluate the prognosis of a known disease. SPL polypeptides, polynucleotides and antibodies are also provided.
