This document describes compositions and methods for inducing an immune response (e.g., a cellular response such as a cell-mediated cytolytic immune response) to a human papillomavirus (HPV) antigen, which can be displayed by HPV or exhibited by infected cells (e.g., cells from cervical and other tumors). The HPV protein can be joined to a stress protein by chemical conjugation or noncovalently using linking moieties, or by fusion (e.g., a recombinant fusion protein). Also described are expression vectors containing sequences encoding HPV antigens and stress proteins, which can be introduced into cells of a subject or cells ex vivo. Also described are compositions that include a stress protein linked to an HPV antigen and another pharmacologically acceptable component and stress protein—HPV antigen fusions and conjugates. These compositions can be used to induce or enhance an immune response against HPV and cells that exhibit HPV antigens, including HPV-associated tumors.

We describe a bis-benzylidine piperidone, RA190, which covalently binds to the ubiquitin receptor RPN13 (ADRM1) in the 19S regulatory particle and inhibits proteasome function, triggering rapid accumulation of polyubiquitinated proteins. Multiple myeloma lines, even those resistant to bortezomib, were sensitive to RA190 via ER stress-related apoptosis. RA190 stabilized targets of human papillomavirus (HPV) E6 oncoprotein, and preferentially killed HPV-transformed cells. After p.o. or i.p. dosing of mice, RA190 distributed to plasma and major organs excepting brain, and potently inhibited proteasome function in skin and muscle. RA190 administration i.p. profoundly reduced growth of multiple myeloma and ovarian cancer xenografts, and oral RA190 treatment retarded HPV+ syngeneic mouse tumor growth, without impacting spontaneous HPV-specific CD8+ T cell responses, suggesting its therapeutic potential. The bis-benzylidine piperidone RA190 is a new orally-available proteasome inhibitor. Multiple myeloma, cervical and ovarian cancers are particularly sensitive to RA190.
