What Challenges are Associated with DNA Microarrays in Toxicology?
Despite their advantages, DNA microarrays also pose certain challenges. The interpretation of complex data sets can be difficult and requires sophisticated bioinformatics tools. Variability in experiment conditions can also affect the reproducibility of results. Furthermore, while DNA microarrays provide information on gene expression, they do not directly measure protein levels or activity, which are often more directly related to toxicological outcomes.
