MYC and bacterial infectious disease: Coincidentally, T cells lacking MAPK/ERK activity in trametinib‐treated tilapia exhibited reduced ability to upregulate c‐Myc and glutaminolysis‐related enzymes in response to TCR stimulation or bacterial infection (Figure 6P,Q; Figure S8F,G, Supporting Information), suggesting that MAPK/ERK signaling is also essential for c‐Myc‐mediated glutaminolysis in tilapia.
