(a) KEGG pathways with significantly differential gene expression from this study were highlighted, including the direction of regulation (up or downregulation). Each colored box has the gene name abbreviated and a number representing the ≥1.5-fold relative to the control. KEGG pathway background images were adapted from www.genome.jp/kegg/ [21,22,23]. (b) HMGCS1 and TM7SF2 mRNA levels, analyzed by quantitative real-time PCR. Values are expressed after normalization for an endogenous control. Data plotted with ggplot and p value were calculated using t. test in R statistical programming language comparing TXA1.HCl vs control. Gene names: ACAT2, acetyl-coenzyme A acetyltransferase 2; HMGCS1, 3-hydroxy-3-methylglutaryl-coenzyme A synthase 1; HMGCR, 3-hydroxy-3-methylglutaryl-coenzyme A reductase; MVK, mevalonate kinase; MVD, mevalonate (diphospho) decarboxylase; IDI1, isopentenyl-diphosphate δ-isomerase 1; FDPS, farnesyl diphosphate synthetase; FDFT1, squalene synthase; SQLE, squalene epoxidase; LSS, lanosterol synthase; CYP51A1, cytochrome P450, family 51, subfamily A, polypeptide 1 (lanosterol 14 α-demethylase); TM7SF2, transmembrane 7 superfamily member 2 (Delta(14)-sterol reductase); MSMO1, methylsterol monooxygenase; NSDHL, NAD(P)-dependent steroid dehydrogenase; DHCR24, 24-dehydrocholesterol reductase; SC5DL, sterol-C5-desaturase-like; DHCR7, 7-dehydrocholesterol reductase.
