Project description:The pharmacological significance of B vitamins, essential for various metabolic processes, and the therapeutic potential of probiotics in gastrointestinal health have been well-documented. However, the interactions between these entities remain poorly understood. In this study, we endeavored to elucidate the potential interplay between B vitamins and probiotics utilizing liquid chromatography-triple quadrupole mass spectrometry, pharmacokinetic modeling, and 16S rRNA gene sequencing. Employing healthy and pseudo-germ-free rat models, we revealed that probiotics significantly improve the absorption of B1, B3, B5, and B12, and that the gut microbiota played a mediating role in this enhanced absorption of B vitamins by probiotics. High-throughput genetic sequencing uncovered a synergistic effect of B vitamins and probiotics in modulating the gut microbiota, particularly increasing the abundance of Verrucomicrobia and Akkermansia. Furthermore, in vitro experiments demonstrated that probiotics used in this study had a relatively minor influence on the production and permeability of B vitamins, while B vitamins did not significantly contribute to the growth, auto-aggregation, and adhesion of probiotics. In summary, a complex network connection exists between B vitamins and probiotics, wherein the gut microbiota emerges as a pivotal factor that cannot be overlooked.

Project description:Obesity and overweight are closely related to diet, and gut microbiota play an important role in body weight and human health. The aim of this study was to explore how Lactobacillus curvatus HY7601 and Lactobacillus plantarum KY1032 supplementation alleviate obesity by modulating the human gut microbiome. A randomized, double-blind, placebo-controlled study was conducted on 72 overweight individuals. Over a 12-week period, probiotic groups consumed 5×10^9 colony-forming units of HY7601 and KY1032), whereas the placebo group consumed the same product without probiotics. After treatment, the probiotic group displayed a reduction in body weight (p <0.001), visceral fat mass (p <0.025), and waist circumference (p <0.007), and an increase in adiponectin (p <0.046), compared with the placebo group. Additionally, HY7601 and KY1032 supplementation modulated bacterial gut microbiota characteristics and beta diversity by increasing Bifidobacteriaceae and Akkermansiaceae, and decreasing Prevotellaceae and Selenomonadaceae. In summary, HY7601 and KY1032 probiotics exert anti-obesity effects by regulating the gut microbiota; hence, they have therapeutic potential for preventing or alleviating obesity and overweight.

Project description:Neonatal hyperbilirubinemia (jaundice) is common in infants, with extremely preterm infants (EPT, <28 weeks gestational age) being at high risk for bilirubin-induced neurotoxicity, resulting in neurodevelopmental impairment. Hyperbilirubinemia is treated using phototherapy to lower unconjugated bilirubin levels. However, the benefits and risks of phototherapy in EPTs have not been well studied, and bilirubin at low levels may be protective as an antioxidant. Phototherapy is associated with markers of oxidative stress in the plasma, but the effects of phototherapy on the hippocampus (HPC) are not known. Bilirubin and insults associated with EPTs impair hippocampal development, a brain structure critical for cognitive function, but their underlying mechanisms remain unknown. The effects of hyperbilirubinemia and phototherapy on the HPC were studied using a Gunn rat model. Jaundiced (jj) and non-jaundiced (Nj) pups were subjected to phototherapy from postnatal day 4 (P4) through P6. The HPC was harvested and processed for RNA sequencing. Serum bilirubin levels were elevated in jj compared to Nj control rats. Phototherapy significantly lowered serum bilirubin levels in jj rats. Compared to Nj rats, 1294 genes were differentially expressed in the jj hippocampal transcriptome and mapped onto the nervous system development, inflammation, and ferroptosis signaling pathways. Phototherapy induces 3297 differentially-expressed genes (DEGs) in rat hippocampal transcriptome compared to untreated rats. These DEGs were annotated to pathways regulating synaptogenesis, long-term potentiation, and neurogenesis. Both hyperbilirubinemia and phototherapy altered expression of 407 genes, which mapped onto hippocampal plasticity functions, including neuritogenesis and long-term potentiation. Our study demonstrates a model for investigating molecular effects of hyperbilirubemia and phototherapy in an EPT-equivalent Gunn rat pup. Our data revealed the effects of hyperbilirubinemia and phototherapy on signaling pathways critical for hippocampal development and plasticity.
