Glycine synthesis from nitrate and glyoxylate mediated by ferroan brucite: An integrated pathway for prebiotic amine synthesis.

Amino acids are present in all known life, so identifying the environmental conditions under which they can be synthesized constrains where life on Earth might have formed and where life might be found on other planetary bodies. All known abiotic amino acid syntheses require ammonia, which is only produced in reducing and neutral atmospheres. Here, we demonstrate that the Fe-bearing hydroxide mineral ferroan brucite [Fe0.33,Mg0.67(OH)2] can mediate the reaction of nitrate and glyoxylate to form glycine, the simplest amino acid used in life. Up to 97% of this glycine was detected only after aci

5-Fluorouracil Loaded Prebiotic-Probiotic Liposomes Modulating Gut Microbiota for Improving Colorectal Cancer Chemotherapy.

The gut microbiota exerts inhibitory effects on the occurrence and progression of colorectal cancer (CRC) through various mechanisms. Compared to traditional microbiota regulation methods, prebiotics and probiotics demonstrate significant advantages in terms of safety and patient adaptability. Their synergy not only improves the intestinal environment but also enhances the host's anti-tumor immune response. 5-Fluorouracil (5-FU) is a first-line chemotherapy drug that has a short half-life and low bioavailability. However, if administered in an untargeted manner, 5-FU also causes adverse reacti…

Aquatic Ferrous Solutions of Prebiotic Mineral Salts as Strong UV Protectants and Possible Loci of Life Origin.

Liposomes are lipid-bilayer vesicles that spontaneously self-assemble from fatty acids (or other amphiphiles) in water by encapsulating surrounding aqueous media. After British scientist Alec Bangham described this phenomenon in the early 1960s, they became a prominent participant in the hypotheses on life origin, particularly in the Lipid World model. A novel scenario of self-sustained Darwinian liposome evolution is based on ever-present natural phenomena of cyclic day/night solar UV radiation and gravitational submersion of liposomes in the Archean aqueous media. One of the assumptions of t

Prebiotic Inulin and Sodium Butyrate Attenuate Obesity-Induced Intestinal Barrier Dysfunction by Induction of Antimicrobial Peptides.

Defects in the mucosal barrier have been associated with metabolic diseases such as obesity and non-alcoholic fatty liver disease (NAFLD). Mice fed a Western-style diet (WSD) develop obesity and are characterized by a diet-induced intestinal barrier dysfunction, bacterial endotoxin translocation and subsequent liver steatosis. To examine whether inulin or sodium butyrate could improve gut barrier dysfunction, C57BL/6 mice were fed a control diet or a WSD ± fructose supplemented with either 10% inulin or 5% sodium butyrate for 12 weeks respectively. Inulin and sodium butyrate attenuated hepatos

Maternal Supplementation of Food Ingredient (Prebiotic) or Food Contaminant (Mycotoxin) Influences Mucosal Immune System in Piglets.

The early life period is crucial for the maturation of the intestinal barrier, its immune system, and a life-long beneficial host-microbiota interaction. The study aims to assess the impact of a beneficial dietary (short-chain fructooligosaccharides, scFOS) supplementation vs. a detrimental dietary environment (such as mycotoxin deoxynivalenol, DON) on offspring intestinal immune system developmental profiles. Sows were given scFOS-supplemented or DON-contaminated diets during the last 4 weeks of gestation, whereas force-feeding piglets with DON was performed during the first week of offspring

Effect of killed whole yeast cell prebiotic supplementation on broiler performance and intestinal immune cell parameters.

Two experiments were conducted to study the effect of CitriStim, a commercial killed whole yeast cell prebiotic, on broiler performance, regulatory T cells, CD4(+) and CD8(+) percentages, and IL-10 and IL-1 mRNA contents of the spleen and cecal tonsils. No immune challenges were imposed in either of the 2 experiments. One-day-old broiler chicks were fed a corn- and soybean meal-based diet supplemented with 0, 0.1, or 0.2% CitriStim (ADM, Decatur, IL) for 35 d. At 21 (P = 0.03) and 35 d (P = 0.02) of age, CitriStim supplementation at 0.2% increased regulatory T cell percentage in the cecal tons

Oligomerization of glycine and alanine on metal(II) octacynaomolybdate(IV): role of double metal cyanides in prebiotic chemistry.

Condensation reactions of amino acid (glycine and alanine) on the surface of metal(II) octacyanomolybdate(IV) (MOCMo) complexes are investigated using high-performance liquid chromatography (HPLC) and electron spray ionizations-mass spectroscopy (ESI-MS).

Prebiotics partially protect offspring from maternal antibiotic-induced obesity risk by altering maternal milk microbiota and gut colonization in Sprague-Dawley rats.

Maternal antibiotic use can increase obesity risk in offspring. Co-administering prebiotics mitigates the risk in rats. How prebiotics and antibiotics interact to affect obesity risk is unknown, but could involve altered milk microbiota that influences offspring gut colonization. Sprague-Dawley rat dams were exposed to antibiotics (low-dose penicillin) and/or prebiotics (oligofructose) during gestation and lactation. Gut and milk microbiota were measured using 16S rRNA sequencing, and metabolic measurements were taken for dams and offspring at weaning (day 21) and 10 days postweaning (day 31).…
