|---|---|---|---|---|
| 1.13.99.1 | palmitate | concomitant treatment with palmitate/bovine serum albumin and activators of PKA (forskolin), PDK/PI3K (insulin), and PKC (TPA) increase Miox activity. Concomitant treatment with respective inhibitors, i.e. H89 (PKA), wortmannin (PI3K), and calphostin (PKC), reduces the activity below the levels induced by palmitate/bovine serum albumin alone, confirming that fatty acid-induced activity is phosphorylation-dependent | Sus scrofa |  |

| 1.13.99.1 | Mus musculus | administration of high-fat diet to CD1 mice over a period of 2-6 weeks induces a tremendous increase in the expression of Miox, exclusively confined to the tubular compartment of the kidney cortex. Besides the increased expression in superficial cortical tubules, it also extends into the deeper cortex. Upregulation of Miox is accompanied by upregulation of mSrebp1 in kidney cells. Rapamycin reverses palmitate/bovine serum albumin-induced Miox, Srebp1, and p53 expression and apoptosis in renal tubular cells | up |
| 1.13.99.1 | Rattus norvegicus | high-fat diet administration over a period of 6 weeks results in a marked time-dependent up-regulation of Miox | up |
| 1.13.99.1 | Sus scrofa | palmitate-conjugated bovine serum albumin causes a dose-dependent increase in Miox expression and activity in LLCPK-1 cells. Concomitant with Miox upregulation, a dose-dependent increased Bax protein expression is observed following palmitate/BSA treatment of LLCPK-1 cells. Concomitant treatment with palmitate/bovine serum albumin and activators of PKA (forskolin), PDK/PI3K (insulin), and PKC (TPA) further increase Miox activity | up |
| 1.13.99.1 | Homo sapiens | treatment of HK-2 cells with palmitate/bovine serum albumin for 24 h induces an increased Miox expression with a concomitant decrease in the membrane-bound precursor form of pre-Srebp1 in the cytoplasmic fraction. No change in the expression of beta-actin or laminB1 is observed. Miox is transcriptionally upregulated by high glucose ambience. A dose-dependent increase in the expression of Miox is observed following insulin treatment. At the same time, a dose-dependent increase in the mSrebp1 is observed. Rapamycin reverses palmitate/bovine serum albumin-induced Miox, Srebp1, and p53 expression and apoptosis in renal tubular cells | up |
