Effect of electric current + GFP expression on endogenous gene expression of the VLM. (A) Genes showing differential expression when exposed to current + GFP and their fold changes. For gene names refer to Table 3. (B) GOTM analysis showing biological function and expected and observed number of genes in each category compared to the number expected from a random set of 111 genes. (C) IPA functional analysis showing the top ten biological functions enriched in the VLMg compared to VLM samples.
