Background: Mixed dementia type - Alzheimer's Disease (AD), cerebral amyloid angiopathy (CAA), and vascular - is vastly recognized as a cause of dementia in older adults. Whereas CAA, primarily leptomeningeal, is a frequent complication in hereditary transthyretin cardiac amyloidosis (TTRCA), it is unusually reported in association with wild-type TTR, with or without polyneuropathy. The knowledge of mixed dementia and wild-type TTR association is even scarcer.

Vitamin B, or pantothenate, forms the molecular "backbone" of coenzyme A (CoA), which is essential for more than a hundred biochemical reactions in humans. Genetic defects that disrupt the CoA pathway cause severe degenerative disorders that may be amenable to treatment with compounds that can bypass the metabolic block. The pantothenate metabolite, 4'-phosphopantetheine (4'PPT), can serve as an alternative substrate for cellular CoA synthesis and may therefore be an essential nutrient in managing disorders where pantothenate cannot meet all metabolic requirements.

Background: Sphingosine-1 phosphate (S1P) is a bioactive lipid molecule that modulates inflammation and hepatic lipid metabolism in MASLD, which affects 1 in 3 people and increases the risk of liver fibrosis and hepatic cancer. S1P can be generated by 2 isoforms of sphingosine kinase (SphK). SphK1 is well-studied in metabolic diseases.

Dystrophin is a critical interacting protein of Nav1.5 that determines its membrane anchoring in cardiomyocytes. Long noncoding RNAs (lncRNAs) are involved in the regulation of cardiac ion channels, while their influence on sodium channels remains unexplored.

Dietary sulfur amino acid restriction (SAAR) elicits various health benefits, some mediated by fibroblast growth factor 21 (FGF21). However, research on SAAR's effects on the heart is limited and presents mixed findings. This study aimed to evaluate SAAR-induced molecular alterations associated with cardiac remodeling and their dependence on FGF21.
