Synergistic Enhancement: Whole Wheat Substrate Improves Memory in Mice by Optimizing Folate Metabolism and Systemic Antioxidant Capacity

Food Bioengineering, EarlyView.
ABSTRACT This study rigorously assessed the impact of folic acid‐fortified whole wheat products on mitigating mild liver injury caused by prolonged excessive folic acid consumption, improving folic acid bioavailability, and enhancing spatial cognitive functions in mice over a 48‐day intervention period.

DNA methylation regulates expression of VEGF-C, and S-adenosylmethionine is effective for VEGF-C methylation and for inhibiting cancer growth

Brazilian Journal of Medical and Biological Research, 2014
DNA hypomethylation may activate oncogene transcription, thus promoting carcinogenesis and tumor development. S-adenosylmethionine (SAM) is a methyl donor in numerous methylation reactions and acts as an inhibitor of intracellular demethylase activity ...

Methylation of the Gpat2 promoter regulates transient expression during mouse spermatogenesis [PDF]

, 2015
Spermatogenesis is a highly regulated process that involves both mitotic and meiotic divisions, as well as cellular differentiation to yield mature spermatozoa from undifferentiated germinal stem cells.

Second‐trimester multimetabolite panel for early preeclampsia rule‐out

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective We aimed to establish a high‐sensitivity, multimetabolite rule‐out model for the development of preeclampsia (PE), prioritizing minimizing false negatives to exclude low‐risk individuals from intensive surveillance confidently. Methods In this prospective, nested case–control study, maternal serum samples were collected between 20+0 ...

Enzymatic Cleavage of S-Adenosylmethionine

Journal of Biological Chemistry, 1959
S-adenosylmethionine, known for some time to be the biological methyl donor in mammalian enzymatic transmethylation reactions (1,2), has more recently been implicated in other transalkylation reactions in bacteria and yeast (3-6). The enzyme system catalyzing the condensation of ATP and methionine to form AMe’ has been found in a variety of tissues and

N6‐Methyladenosine (m6A) in Liver Disease: Pathogenic Mechanisms and Therapeutic Potential

iNew Medicine, EarlyView.
ABSTRACT Accumulating evidence highlights the critical role of epigenetic modifications, particularly N6‐methyladenosine (m6A), in liver disease. As the most abundant RNA modification in eukaryotic cells, m6A is dynamically regulated by multicomponent m6A methyltransferases (e.g., METTL3 and METTL14), demethylases (FTO and ALKBH5), and m6A‐binding ...

The efficiency of metabolic impact of S-adenosylmethionine and meldonium on parameters of lipid profile and insulin resistance during comorbid course of nonalcocholic steatohepatitis, obesity and chronic kidney disease stage І-ІІ

Zaporožskij Medicinskij Žurnal, 2018
Objective – to investigate the influence of the complex of S-adenosylmethionine (Agepta) and meldonium (Vasonat) on the course of NASH with obesity and CKD, the state of the lipid profile of the blood, and the degree of insulin resistance.

Noncanonical Nucleotides in the Genome Around the Maternal‐Zygotic Transition

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In this paper, Kazzazi et al. provide a comprehensive review of the dynamics of nonconventional nucleotides in the genome during early developmental stages, hypothesizing a potential role for these nucleotides in the activation of the zygotic genome. ABSTRACT From the very moment of fertilization and throughout development, the cells of animal embryos ...

Fresh Insights Into SLC25A26: Potential New Therapeutic Target for Cancers: A Review

Oncology Reviews
SLC25A26 is the only known human mitochondrial S-adenosylmethionine carrier encoding gene. Recent studies have shown that SLC25A26 is abnormally expressed in some cancers, such as cervical cancer, low-grade glioma, non-small cell lung cancer, and liver ...
