Presence of N-acetylneuraminic acid in the lung during postnatal development [PDF]

open access: yesEuropean Journal of Histochemistry, 2020
Sialic acids, particularly N-acetylneuraminic acid (Neu5Ac), are present as terminal components of rich and complex oligosaccharide chains, which are termed glycans, and are exhibited on the cell surfaces, especially on epithelial cells.

One-pot biosynthesis of N-acetylneuraminic acid from chitin via combination of chitin-degrading enzymes, N-acetylglucosamine-2-epimerase, and N-neuraminic acid aldolase [PDF]

open access: yesFrontiers in Microbiology, 2023
N-acetylneuraminic acid (Neu5Ac) possesses the ability to promote mental health and enhance immunity and is widely used in both medicine and food fields as a supplement.

COLOMINIC ACID, A POLYMER OF N-ACETYLNEURAMINIC ACID [PDF]

open access: yesThe Journal of Experimental Medicine, 1958
All acidic carbohydrate has been isolated from the culture medium of the enteric microorganism E. coli K235 L+O. This substance has been named colominic acid. N-acetylneuraminic acid, which has been isolated from the hydrolysate of colominic acid, is believed to be the monomer unit from which colominic acid is constituted.

N-acetylneuraminic acid: A scrutinizing tool in oral squamous cell carcinoma diagnosis [PDF]

open access: yesDental Research Journal, 2017
Background: Oral cancer has one of the highest mortality rate among other malignancies. An attempt has been made to assess the genetic expression of a cell surface glycoprotein component - sialic acid released by the malignant cells which will reflect on

The fate of orally administered sialic acid: First insights from patients with N-acetylneuraminic acid synthase deficiency and control subjects [PDF]

open access: yesMolecular Genetics and Metabolism Reports, 2021
Background: In NANS deficiency, biallelic mutations in the N-acetylneuraminic acid synthase (NANS) gene impair the endogenous synthesis of sialic acid (N-acetylneuraminic acid) leading to accumulation of the precursor, N-acetyl mannosamine (ManNAc), and ...

Serum N-Acetylneuraminic Acid Is Associated with Atrial Fibrillation and Left Atrial Enlargement [PDF]

open access: yesCardiology Research and Practice, 2020
Purpose. Recent studies have indicated that N-acetylneuraminic acid (Neu5Ac) plays a key role in severe coronary artery diseases, involving RhoA signaling pathway activation, which is critically involved in cardiac fibrosis.

High fat diet-induced inflammation and oxidative stress are attenuated by N-acetylneuraminic acid in rats. [PDF]

open access: yesJ Biomed Sci, 2015
Serum sialic acid levels are positively correlated with coronary artery disease and inflammation. Although sialic acid is a non-specific marker, it is considered sensitive likely due to its influence in sialylation of glycoprotein structures all over the

N-Acetylneuraminic acid attenuates hypercoagulation on high fat diet-induced hyperlipidemic rats [PDF]

open access: yesFood & Nutrition Research, 2015
Background and objective: N-Acetylneuraminic acid (Neu5Ac), a type of sialic acid, has close links with cholesterol metabolism and is often used as a biomarker in evaluating the risk of cardiovascular diseases.

Hydroxylation of N-acetylneuraminic Acid Influences the in vivo Tropism of N-linked Sialic Acid-Binding Adeno-Associated Viruses AAV1, AAV5, and AAV6 [PDF]

open access: yesFrontiers in Medicine, 2021
Adeno-associated virus (AAV) vectors are promising candidates for gene therapy. However, a number of recent preclinical large animal studies failed to translate into the clinic. This illustrates the formidable challenge of choosing the animal models that
