Of particular relevance to this study, we found that axon guidance, one of the several endogenous mechanisms for recovery after brain ischemia [16], was among the pathways overrepresented in the Reactome pathways, with the appearance of proteins like IQGAP2, Trio, Teneurin-4, Semaphorin 6A, Serpine2, Spondin-1, Ephrin type receptor 5. The gene discussed is SEMA6A; the disease is brain ischemia.
