The medullary thick ascending limb (MAL), but not the medullary collecting tubule (MCT), has been shown to have an impaired adenylate cyclase (AC) responsiveness to ADH and a selective hypoplasia in Brattleboro diabetes insipidus (DI) rats.

Results indicate that 1. in MAL of ADH-treated rats, AC responses to in vitro AVP and glucagon and Na-K-ATPase activity increased to the same extent as did epithelium volume (60-80%); 2. changes in the other segments were independent of any morphological alteration.

During the past three decades aldehyde reductase (AKR1A) and aldose reductase (AKR1B) have been extensively investigated, and the gene regulation of AKR1B has been noted to be heavily influenced by hyperglycemic state and high glucose ambience in various culture systems.

Transfection of the human promoter into ethoxyquin-treated mouse 3T3 cells induces a 3.5-fold increase in promoter activity and a CHOP-C/EBP band appears on gel shifts performed with the 5' probe from the human aldehyde reductase promoter.

Oxidation of ethanol via alcohol dehydrogenase (ADH) explains various metabolic effects of ethanol but does not account for the tolerance.
|
155 |
15554233
|
This fact, as well as the discovery of the proliferation of the smooth endoplasmic reticulum (SER) after chronic alcohol consumption, suggested the existence of an additional pathway which was then described by Lieber and DeCarli, namely the microsomal ethanol oxidizing system (MEOS), involving cytochrome P450.
|
156 |
15554233
|
After chronic ethanol consumption, the activity of the MEOS increases, with an associated rise in cytochrome P450, especially CYP2E1, most conclusively shown in alcohol dehydrogenase negative deer mice.
|
157 |
15554233
|
CYP1A2 and CYP3A4, two other perivenular P450s, also sustain the metabolism of ethanol, thereby contributing to MEOS activity and possibly liver injury.
