Methods and compositions for specifically targeting human hepatocellular carcinoma cells

摘要

Particular aspects of the present invention provide methods and compositions for the targeting and/or treating hepatocellular carcinoma (HCC) cells to affect cancer cell growth or viability. Exemplary methods and compositions relate to cell-associated HCC proteins (e.g., SEQ ID NOS:1-8, corresponding to PGMRCI (prostaglandin receptor membrane component 1), SEMA5A (semaphorin 5A), SLC2A2 (solute carrier family member), ABCC2 (ATP-binding cassette subfamily C member 2) and HAL (histidine ammonia lyase)), and are based, at least in part, upon the discovery that specific target genes and/or gene products are up or down-regulated in diseased tissue relative to normal tissue or in tissue of patients having other ailments. Inventive compositions comprise, for example, antibodies, antisense and siRNA agents.
