Vitamin D metabolism is altered during aging alone or combined with obesity in male mice
We report for the first time the effect of aging process alone or in combination with obesity on vitamin D metabolism as a whole and leading to modulation of 25(OH)D plasma levels. Our data strongly suggest that the enzymes involved in vitamin D metabolism, notably in liver, kidneys, and adipose tissue, are transcriptionally modified under aging or combined effect of aging and obesity, contributing to the reduction of the plasma 25(OH)D. AbstractAging and obesity are associated with a decrease in plasma 25-hydroxyvitamin D (25(OH)D) levels. In the context of a growing aging population and the rising incidence of obesity, w...

VD/VDR-mediated ATG16L1 activation reduces Alzheimer ’s disease-like pathology and cognitive decline
ConclusionCCE exhibits potential in safeguarding hippocampal neurons against AD-induced harm, stimulating autophagy, and suppressing inflammation. These effects may be regulated by VD/VDR/ATG16L1 signaling. (Source: Molecular and Cellular Toxicology)

Vitamin D3 improves iminodipropionitrile-induced tic-like behavior in rats through regulation of GDNF/c-Ret signaling activity
AbstractChildren with chronic tic disorders (CTD), including Tourette syndrome (TS), have significantly reduced serum 25-hydroxyvitamin D [25(OH)D]. While vitamin D3 supplementation (VDS) may reduce tic symptoms in these children, its mechanism is unclear. The study aim was to investigate the effects and mechanisms of vitamin D deficiency (VDD) and VDS on TS model behavior. Forty 5-week-old male Sprague –Dawley rats were randomly divided into (n = 10 each): control, TS model, TS model with VDD (TS + VDD), or TS model with VDS (TS + VDS; two intramuscular injections of 20,000 IU/200 g) groups. The VDD model ...

Identification of trans-genus biomarkers for early diagnosis of intestinal schistosomiasis and progression of gut pathology in a mouse model using metabolomics
by Peerut Chienwichai, Phornpimon Tipthara, Joel Tarning, Yanin Limpanont, Phiraphol Chusongsang, Yupa Chusongsang, Nuttapohn Kiangkoo, Poom Adisakwattana, Onrapak Reamtong Schistosomiasis is one of the most devastating human diseases worldwide. The disease is caused by six species ofSchistosoma blood fluke; five of which cause intestinal granulomatous inflammation and bleeding. The current diagnostic method is inaccurate and delayed, hence, biomarker identification using metabolomics has been applied. However, previous studies only investigated infection caused by oneSchistosoma spp., leaving a gap in the use of biomarke...

Two Sesterterpene Synthases from Lentzea atacamensis Demonstrate the Role of Conformational Variability in Terpene Biosynthesis
Angew Chem Int Ed Engl. 2024 Feb 19:e202401539. doi: 10.1002/anie.202401539. Online ahead of print.ABSTRACTMining of two multiproduct sesterterpene synthases from Lentzea atacamensis resulted in the identification of the synthases for lentzeadiene (LaLDS) and atacamatriene (LaATS). The main product of LaLDS (lentzeadiene) is a new compound, while one of the side products (lentzeatetraene) is the enantiomer of brassitetraene B and the other side product (sestermobaraene F) is known from a surprisingly distantly related sesterterpene synthase. LaATS produces six new compounds, one of which is the enantiomer of the known sest...

Tremendous Fidelity of Vitamin D3 in Age-related Neurological Disorders
AbstractVitamin D3 (VD) is a secosteroid hormone and shows a pleiotropic effect in brain-related disorders where it regulates redox imbalance, inflammation, apoptosis, energy production, and growth factor synthesis. Vitamin D3 ’s active metabolic form, 1,25-dihydroxy Vitamin D3 (1,25(OH)2D3 or calcitriol), is a known regulator of several genes involved in neuroplasticity, neuroprotection, neurotropism, and neuroinflammation. Multiple studies suggest that VD deficiency can be proposed as a risk factor for the development of several age-related neurological disorders. The evidence for low serum levels of 25-hydroxy Vitamin...
