25383759 These findings reveal structural adaptation that facilitates selective catalysis and mechanism responsible for diverse substrate specificity within the LRAT-like enzyme family
25260806 LRAT hypermethylation was associated with decreased mRNA levels in colorectal cancer clinical specimens.
25236354 lecithin retinol acyltransferase affects all-trans retinoic acid levels and has a role in retinoid sensitivity in malignant melanoma cells.
24613493 Lecithin-retinol acyltransferase is a thermostable and highly active enzyme with a likely mode of interfacial activation.
24433184 high LRAT expression in melanoma might be important in removing retinol as substrate for RA production, thereby inducing signalling pathways leading to dedifferentiation, proliferation and anti-apoptosis
23890161 Functional hepatic stellate cells coexpressing both LRAT and CRBP-1, that continue to maintain the ability to store vitamin A, contribute in part to the development of portal and parenchymal fibrogenesis in patients with viral hepatitis.
22605381 Data show that acyl-modified forms of HRAS-like tumor suppressors HRASLS2 and HRASLS3 mimicking lipolytic activity of lecithin retinol acyltransferase LRAT.

22559933 A genetic defect was identified in LRAT as a novel cause of retinitis punctata albescens.
21465477 This study showed that malignant melanoma cells are able to esterify all-trans retinol and subsequently isomerize all-trans retinyl esters (RE) into 11-cis retinol, whereas their benign counterparts-melanocytes are not able to catalyze these reactions.

17438524 LRAT mutations are likely a rare cause of Leber congenital amaurosis among patients from North America.
17011878 The phenotype of patients with mutations in LRAT is similar to that of patients with mutations in RPE65, suggesting the need to systematically screen both genes in case of typical phenotype.
16939223 These experiments are consistent with an expanded role for LRAT function as a protein palmitoyl transferase.
16115871 LRAT has a role in retinoid absorption and storage
15474300 Results provide evidence that multiple LRAT mRNA transcripts, which are expressed in a tissue-specific manner, may result from differential splicing of the 5'UTR region and the use of multiple polyadenylation signals in the 3'UTR.
15161698 LRAT has a role in preventing progression of invasive bladder cancer
14596594 Conserved residues Cys-161 and His-60 form the essential catalytic dyad of LRAT that represents a novel thiol protease motif, which functions in an acyltransferase reaction.
14581364 LRAT expression is higher in renal tumors with an indolent biological behavior
