Abstract:
Non-mammalian models of CIPN remain relatively sparse, but the knowledge gained from the few published studies suggest that these species have great potential to serve as a discovery platform for new pathways and underlying genetic mechanisms of CIPN. These models permit large-scale genetic and pharmacological screening, and they are highly suitable for in vivo imaging. CIPN phenotypes described in rodents have been confirmed in those models, and conversely, genetic players leading to axon de- and regeneration under conditions of chemotherapy treatment identified in these non-mammalian species have been validated in rodents. Given the need for non-traditional approaches with which to identify new CIPN mechanisms, these models bear a strong potential due to the conservation of basic mechanisms by which chemotherapeutic agents induce neurotoxicity.
Insights
Non-mammalian models offer a powerful platform for discovering new chemotherapy-induced peripheral neuropathy (CIPN) pathways and genetic mechanisms. These models enable large-scale screening and in vivo imaging, validating findings in rodents.
Area of Science:
- Neuroscience
- Toxicology
- Genetics
Background:
- Chemotherapy-induced peripheral neuropathy (CIPN) is a significant challenge in cancer treatment.
- Current research on CIPN mechanisms is limited, necessitating novel approaches.
- Non-mammalian models are underutilized but show promise for CIPN research.
Purpose of the Study:
- To highlight the potential of non-mammalian models for uncovering new CIPN pathways and genetic underpinnings.
- To emphasize the utility of these models for large-scale genetic and pharmacological screening.
- To demonstrate the translational value of non-mammalian models in CIPN research.
Main Methods:
- Review of existing literature on non-mammalian models in CIPN research.
- Comparative analysis of CIPN phenotypes and genetic mechanisms between non-mammalian models and rodents.
- Discussion of the suitability of non-mammalian models for in vivo imaging and screening.
Main Results:
- Non-mammalian models exhibit conserved CIPN phenotypes observed in rodents.
- Genetic factors identified in non-mammalian models for axon regeneration have been validated in rodent studies.
- These models facilitate efficient large-scale genetic and pharmacological screening.
Conclusions:
- Non-mammalian models are valuable tools for identifying novel CIPN mechanisms due to conserved neurotoxicity pathways.
- Their suitability for in vivo imaging and screening accelerates discovery.
- These models hold significant potential for advancing our understanding and treatment of CIPN.
