英文摘要
DESCRIPTION (provided by applicant):
The National Cancer Institute has a need for development, standardization, and
validation of assays that can quickly and cheaply determine or predict
organ-specific toxicities of potential cancer therapeutic agents. The
objective of the proposed project is to develop an in vitro liver cell assay
to determine or predict potential dose-limiting hepatocellular injury and
injury to the biliary tract by anticancer agents in humans. The research will
focus on the development, verification, and validation of multicell systems
that can meet that objective, in particular precision-cut liver slices and
co-cultures of hepatocytes and biliary epithelial cells. The assay to be
developed will be able to (1) discriminate the types of injury that can be
produced in liver by anticancer agents, (2) discriminate differences in
analogue sensitivity, (3) discriminate interspecies differences in
sensitivity, and (4) identify indicators of diagnostic value in serum for
identifying specific types of liver injury in humans. The research will
evaluate known clinical diagnostics for their utility, sensitivity, and
fidelity in detecting and quantifying the types of liver injury produced by
anticancer agents in the assay and will search for novel indicators, using
proteomic techniques in the R21 phase, that may be superior for identifying
target cell injury and mechanisms in the assay and be clinically relevant and
valuable. Reference compounds used to develop and validate the assay will be
primarily anticancer agents with specific, well-defined, representative
toxicities in animals and/or humans. The R33 phase will focus on developing
the full capabilities of this assay as an important and critical part of the
in vitro toxicity test battery needed by the NCI to screen for target organ
toxicities and to aid in predicting safe dose levels and regimens for clinical
trials.
