Value of CDX2, uillin, and alpha-methylacyl coenzyme A racemase
immunostains in the distinction between primary adenocarcinoma of the bladder and secondary colorectal adenocarcinoma.
In enzymology, alpha-methylacyl-CoA racemase
(AMACR) is an enzyme that catalyses chemical reactions.
Abbreviations: PSAT, phosphoserine aminotransferase; PSP, phosphoserine phosphatase; SR, serine racemase
D-serine is produced from L-serine by the enzyme serine racemase
which can be a cause of the decreased serum levels of L-serine as was observed in our study.
(AMACR) and prostate-cancer risk: a meta-analysis of 4,385 participants.
Diagnostic utility of alpha-methylacyl CoA racemase
(P504S) & HMWCK in morphologically difficult prostate cancer.
The gene alr encodes for alanine racemase
and is involved in the peptidoglycan synthesis, yet the function of this enzyme in Mycoplasma species is not clear.
Supportive findings include the expression of proximal convoluted tubule markers (CD10 and alpha-methylacyl-CoA racemase
; AMACR), distal nephron proteins (parvalbumin, high-molecular-weight CK, and CD19) [1, 6], and the detection of intercalated cells and cells similar to those in the proximal tubule using electron microscopy [1, 7, 8].
Tomaszewski, "Role of carbonic anhydrase IX, [alpha]-methylacyl coenzyme a racemase
, cytokeratin 7, and galectin-3 in the evaluation of renal neoplasms: a tissue microarray immunohistochemical study," Annals of Diagnostic Pathology, vol.
Immunohistochemistry is helpful in differentiating these entities as CA-IX and CD10 are most frequently expressed in CCRCC than Mullerian CCC, whereas CK7, Napsin-A, and methylacyl-coenzyme-A racemase
(AMACR) show a reverse pattern of expression .
Specifically, neuronal activity facilitated [H.sub.2]S production and sulfhydrated serine racemase
(SR) formation, and use of an [H.sub.2]S donor enhanced hippocampal D-serine availability, expedited hippocampal LTP via a D-serine-dependent pathway, and slowed age-related LTP impairment .
D-serine is synthetized by isomerization of L-serine, in a reaction catalyzed by the enzyme serine racemase
[24, 25], which, in addition to synthesize D-serine, also catalyzes the [alpha],[beta]-elimination of water from L-serine or D-serine to produce pyruvate and ammonia  (Figure 1).
