Biological Role of Aldo–Keto Reductases in Retinoic Acid Biosynthesis and Signaling

The mitogenic role of AKR1B10 may be related to the depletion of retinoic acid (due to excessive AKR1B10 activity) and subsequent loss of cell differentiation and cancer .Retinol and its derivatives retinaldehyde and retinoic acid (RA) are essential for the growth and maintenance of many body tissues, such as skin, bone, and vasculature, as well as for the visual cycle (11-cis-retinaldehyde) and immune function. They also play a role in reproduction, embryonic growth, and development. Abstract. The aldo-keto reductase (AKR) protein superfamily contains > 190 members that fall into 16 families and are found in all phyla.

Introduction. The Aldo-Keto Reductases (AKRs) are a superfamily of NAD(P)H linked oxidoreductases that are generally cytosolic monomeric (37 kDa) proteins that reduce aldehydes and ketones to their corresponding primary and secondary alcohols [1-3].They are present in prokaryotes and eukaroytes and fall into 15 families, for a . Several aldo–keto reductase (AKR) enzymes from subfamilies 1B and 1C show retinaldehyde reductase activity, having low K m and k cat values. Only AKR1B10 and 1B12, with all-trans-retinaldehyde, and AKR1C3, with 9-cis-retinaldehyde, display high catalytic efficiency.Major structural determinants for retinaldehyde isomer specificity are . Aldo–keto reductases comprise of AKR1C1–AKR1C4, four enzymes that catalyze NADPH dependent reductions and have been implicated in biosynthesis, intermediary metabolism, and detoxification. Recent studies have provided evidences of strong correlation between the expression levels of these family members and the . NADP(H)-dependent cytosolic aldo-keto reductases (AKRs) have been added to the group of enzymes which contribute to oxidoreductive conversions of retinoids. Recently, we found that two members from the AKR1B subfamily (AKR1B1 and AKRB10) were active in the reduction of all- trans - and 9- cis -retinaldehyde, with K m values in .

Aldo-keto reductases (AKRs) are a major superfamily of NAD (P)H-dependent oxidoreductases. They use a conserved catalytic mechanism and rate is often governed by cofactor release. There are 15 human AKRs implicated in health and disease. Inhibitor programs exist world-wide to develop therapeutics and chemical probes for AKRs.
