英文摘要
Project Summary/Abstract
Identification of susceptibility to chemotherapy induced peripheral neuropathy using patient stem cell derived
sensory neurons
Current understanding of the mechanisms responsible for chemotherapy induced peripheral neuropathy
(CIPN) is extremely limited and more importantly, there is no way of identifying who is at risk. In this proposal,
we will test the utility of an in-vitro model of CIPN using human neurons generated from patient-derived stem
cells for the study of CIPN risk. Sensory neurons, the neurons most commonly affected in CIPN, will be
generated from iPSC lines generated from patients treated with the chemotherapeutic paclitaxel who did, or did
not, develop CIPN. The susceptibility of these neurons to paclitaxel-induced neurotoxicity will be measured to
determine whether neurons from individuals with CIPN are more vulnerable to chemotherapeutic neurotoxicity
than those from their age, gender and dose matched controls who did not develop CIPN. The sensory neurons
will also be exposed to other classes of chemotherapeutic agents, which also cause peripheral neuropathy
despite distinct antineoplastic mechanisms, to determine whether sensory neuron susceptibility to
chemotherapy-induced toxicity is generic or specific to certain classes of drug. These findings could contribute
to identifying patients at risk for CIPN prior to their treatment and understanding the factors which contribute to
CIPN susceptibility.
