MSMO1 and infection: In fact, we found induced expression of methylsterol monooxygenase 1 (EC 1.14.13.72) (MSMO1; Entrez gene identifier 6307) and the lipase A/cholesterol esterase (EC 3.1.1.13) (LIPA; Entrez gene identifier 3988) plus general enrichment of the steroid biosynthesis pathway among the host genes with increased expression during infection, which is consistent with increased cholesterol synthesis (Fig. 5A and Table S2).
