The present invention provides compositions and methods for treating and preventing cancer. The invention comprises an inhibitor of epigenetic regulators, including MLL1, MLL2, MOZ, menin, WDR5, or a combination thereof. In one embodiment, the invention provides a personalized method of treating a cancer as dependent upon its epigenetic signature.

Embodiments provided herein include methods, compositions, and uses of aromatic alcohols to increase the potency of antifungal agents.

Materials and methods for regulating lipid abundance by modulating Protease Activated Receptor 1 (PAR1) and Protease Activated Receptor 2 (PAR2) levels arc provided herein. In a first aspect, this document features a method that includes (a) identifying a mammal as having a condition characterized at least by impaired lipid production, impaired cholesterol production, or both impaired lipid production and impaired cholesterol production; and (b) administering to the mammal an inhibitor of PAR1 and/or PAR2 in an amount effective to increase lipid production and/or cholesterol production in the mammal.

The present invention discloses a heparin nano drug carrier system loaded with an amino anti-tumor drug. The drug carrier system is a conjugate formed by loading the amino anti-tumor drug on a PEGylated heparin molecule. A natural polysaccharide heparin that is biodegradable and has good compatibility and high availability is used as a drug carrier, and by combining PEG modification and the amino anti-tumor drug, nanoparticles have a significantly enhanced anti-tumor therapeutic index and biological safety in in-vivo therapy when compared with free drugs.
