We evaluated the usefulness of double immunohistochemical staining for cytokeratin (CK)5/6 and alpha-methylacyl coenzyme A racemase (AMACR) applied sequentially on 1 slide by assessing 223 foci in 110 consecutive prostate specimens. Double-chromogen reaction was used to visualize the antibodies: brown for CK5/6 and red for AMACR. Staining was scored as diffuse, focal, or negative. To establish ...

Congenital defects of bile acid synthesis are rare disorders that cause progressive liver dysfunction. We present a case alpha methylacyl-CoA racemase (AMACR) deficiency with non-spherocytic hemolytic anemia who presented rapidly severe cholestasis and failure normal gamma-glutamyl transferase levels. After extensive investigation, he was found to have AMACR HBB gene mutation associated possibl...

α-Methylacyl-CoA racemase (Amacr) is an enzyme at the merging point of two important pathways of lipid metabolism: elimination of methyl-branched fatty acids and synthesis of bile acids. Amacr is regarded as obligatory for these processes. Patients with Amacr-deficiency suffer from adult onset sensory motor neuropathy and/or severe neonatal cholestasis with coagulopathy and fat-soluble vitamin ...

We assessed the utility of using a p63/a-methylacyl-coenzyme-A racemase (AMACR) antibody cocktail on destained H&E-stained sections. We transferred 61 stored (7-11 months old) and 10 recent (<1 month old) H&E-stained sections of prostate needle biopsy tissues to charged slides and subsequently stained them with a p63/AMACR immunohistochemical antibody cocktail. The AMACR and p63 staining intens...

Background: Although prostate-specific antigen (PSA) is a prototypic biomarker for prostate cancer, it has poor specificity. Expression of -methylacyl-CoA racemase (AMACR), which is involved in the conversion of Rstereoisomers of branched-chain fatty acids to S-stereoisomers, has been shown to be specifically increased in prostate cancer epithelia. However, attempts to detect AMACR in circulati...

BACKGROUND Hyperplastic polyps (HP) and sessile serrated adenomas (SSA) share morphological similarities. In this immunohistochemical study we chose a panel of potential relevant and promising biomarkers including α-methylacyl-coenzyme A racemase (AMACR; p504s), which is involved in the degradation of branched chained fatty acids derivates, and analysed a cohort of HPs and SSAs in order to iden...

The present study examines the expression of p63, glutathione S-transferase-pi (GSTP1) and alpha-methylacyl-CoAracemase (AMACR) in serial slices in proliferative inflammatory atrophy (PIA) in order to implicate that some of the basal cells are probably the putative human prostate carcinoma stem cells (PHPCSC). Archived tissue sections obtained after radical prostatectomy from cases (n=30) compr...

BACKGROUND To assess if the variants of (R)-alpha-methyl-CoA racemase (AMACR) gene would be associated with the risk of sporadic prostate cancer in ethnically homogenous Koreans. MATERIALS AND METHODS We enrolled 194 patients with prostate cancer and 169 healthy controls. A total of 17 single nucleotide polymorphisms of the AMACR gene were selected. The distribution of each genotype and haplo...

BACKGROUND. Expression of the a-methylacyl-CoA racemase (AMACR) gene has been established as a sensitive and specific biomarker for the diagnosis of prostate cancer. An initial study has also suggested that the risk of familial (but not sporadic) prostate cancer may be associated with germline variation in the AMACR gene. METHODS. In a study of brothers discordant for the diagnosis of prostate ...

41 Background: A promising prostate cancer biomarker, alpha-methylacyl-CoA racemase (AMACR), has demonstrated the ability to distinguish cancer from healthy and benign cells with high sensitivity and specificity. However the lack of a good clinical assay has limited its translation into the clinic. Here we report on the development of a single use disposable biosensor for AMACR detection. MET...
