A study employing microarray assays with the LAAO of Ophiophagus hannah (OH-LAAO) on human breast adenocarcinoma cells (MCF-7) showed the expression of 178 genes after treatment with the enzyme, of which 27 were expressed due to the cytotoxic action of LAAO in relation to apoptosis, autophagy, cell cycle, DNA replication, oxidative stress, proteolysis, and intracellular signalling37. Here, IL4I1 is linked to breast adenocarcinoma.
