The largest number of target genes deregulated by HB treatment is engaged in regulation of apoptosis via three specific pathways: NF‐kappa B signaling (eight genes directly engaged in apoptosis associated pathways), toxoplasmosis (eight genes associated with cellular immune response), and direct apoptosis (seven genes including mediation via BIRC6 family of proteins; Fig. 4). The gene discussed is BIRC6; the disease is toxoplasmosis.
