Future research will focus on: (1) analyzing NEXN expression at different AAA stages via WB/qPCR; (2) examining the correlation between NEXN expression and neutrophil infiltration in AAA models, along with immunofluorescence-based co-localization analysis; (3) using CRISPR-based knockdown/overexpression models to investigate its role in AAA and inflammation; and (4) performing metabolic analyses to assess its impact on amino acid metabolism. Here, NEXN is linked to triple-A syndrome.
