Research presented at the Vancouver Autophagy Symposium (VAS) 2014 suggests that
autophagy's influence on health and disease depends on tight regulation and
precision targeting of substrates. Discussions recognized a pressing need for
robust biomarkers that accurately assess the clinical utility of modulating
autophagy in disease contexts. Biomarker discovery could flow from investigations
of context-dependent triggers, sensors, and adaptors that tailor the autophagy
machinery to achieve target specificity. In his keynote address, Dr. Vojo Deretic
(University of New Mexico) described the discovery of a cargo receptor family
that utilizes peptide motif-based cargo recognition, a mechanism that may be more
precise than generic substrate tagging. The keynote by Dr. Alec Kimmelman
(Harvard Medical School) emphasized that unbiased screens for novel selective
autophagy factors may accelerate the development of autophagy-based therapies.
Using a quantitative proteomics screen for de novo identification of
autophagosome substrates in pancreatic cancer, Kimmelman's group discovered a new
type of selective autophagy that regulates bioavailable iron. Additional
presentations revealed novel autophagy regulators and receptors in metabolic
diseases, proteinopathies, and cancer, and outlined the development of specific
autophagy inhibitors and treatment regimens that combine autophagy modulation
with anticancer therapies. VAS 2014 stimulated interdisciplinary discussions
focused on the development of biomarkers, drugs, and preclinical models to
facilitate clinical translation of key autophagy discoveries.
