Abstract: Re-folded human serum albumin (rfHSA) and use thereof for anti-tumor are disclosed. The rfHSA comprises the primary amino acid sequence of naive human serum albumin, in which the rfHSA in a solution is oval shape, not fibrillar, and the naive HSA is globular. The rfHSA is used for treating cancer or a tumor in a subject in need thereof The rfHSA may also be used as a reagent for detecting the presence of a cancer cell associated with integrin ?1 or serine/threonine protein kinase Akt and extracellular signal-regulated kinase 1/2 (ERK1/2) in a tumor sample or as a reagent for inhibiting phosphorylation of Akt and ERK 1/2 in a cancer cell sample. A cell lysate of a cancer cell treated with rfHSA, a vaccine composition comprising the cancer cell lysate, and use thereof are also disclosed. Also disclosed is a method tor preparing rfHSA.

Abstract: A pure, water-soluble polypeptide containing one or more monomers of a VP1 protein of a foot-and-mouth disease virus; or a pure, water-insoluble polypeptide comprising two or more monomers of a VP1 protein of a foot-and-mouth disease virus. Also disclosed are a vaccine containing the polypeptide, a method of producing the polypeptide, and a method of inducing an immune response in a subject by administering to the subject an effective amount of the polypeptide.
