Kidney organoids are powerful tools for renal disease modeling and nephrotoxicity screening, yet their limited structural complexity-particularly the underdevelopment of ureteric bud (UB) lineages-remains a major limitation. A novel differentiation protocol is developed that short-term activation of retinoic acid (RA) signaling during the early intermediate mesoderm (IM) stage, enabling co-induction of anterior and posterior IM lineages. This eliminates the need for UB co-culture and supports the formation of kidney organoids containing complete nephron segments.

(sweet flag), a medicinal plant, especially its rhizome, shows strong antioxidant and anti-inflammatory effects; however, its efficacy in treating intestinal inflammation and obesity is still unexplored. In this study, we investigated the prebiotic activity of sweet flag rhizome extract (SRE) and its preventive effects against high-fat diet (HFD)-induced obesity and colonic inflammation. The prebiotic activity was assessed based on the prebiotic activity scores of four probiotic strains.

Article Synopsis
  • - Excessive sugar intake alters gut microbiota, which is linked to obesity and metabolic issues; this study focused on monosaccharides (glucose and fructose) versus fructooligosaccharides (FOS) effects in germ-free mice.
  • - Mice consuming glucose and fructose showed increased fat accumulation and larger fat cells compared to those fed FOS, which led to healthier metabolic function and significant activation of a key protein involved in metabolism.
  • - FOS not only reduced metabolic problems but also increased goblet cells in the intestinal lining, suggesting beneficial effects that occur independently of the gut microbiota.

Scope: Long-term consumption of excessive dietary advanced glycation end-products such as N-carboxymethyl-lysine (CML), which are produced by the Maillard reaction during food thermal processing, leads to nonalcoholic fatty liver disease (NAFLD) along with high fat consumption. The study previously finds that administration of Lactococcus lactis KF140 (LL-KF140) detoxifies CML by decreasing CML absorption both in a rat model and clinical trial.

Methods And Results: The present study evaluates the ameliorative effect of LL-KF140 on NAFLD and fatty liver-related biomarkers in a mouse model induced by CML and high fat.

Resistant starch serves as a prebiotic in the large intestine, aiding in the maintenance of a healthy intestinal environment and mitigating associated chronic illnesses. This study aimed to investigate the impact of resistant starch-enriched brown rice (RBR) on intestinal health and functionality. We assessed changes in resistant starch concentration, structural alterations, and branch chain length distribution throughout the digestion process using an in vitro model.

The irreversible glycation of proteins produces advanced glycation end products (AGEs) which are triggered to bind the receptor for AGE (RAGE), thereby activating mitogen-activated protein kinase/nuclear factor-κB signaling pathway and stimulating proinflammatory cytokines, ultimately leading to chronic disorders. In this study, we focus the promoting effect of N-carboxymethyl-lysine (CML), one of the most dietary AGEs, on non-alcoholic fatty liver disease (NAFLD) and evaluated NAFLD-related biomarkers. Oxidative stress and hepatic steatosis were assessed in oleic acid (OA)-induced HepG2 cells.

  • Radish greens contain polysaccharides, particularly rhamnogalacturonan-I, which have health benefits.
  • This study explored the prebiotic effects of radish green polysaccharide (RGP) on gut health and obesity, finding that a 0.5% concentration of RGP outperformed inulin in promoting short-chain fatty acid production in various prebiotic strains.
  • RGP also showed potential in reducing fat accumulation in fat cells, suggesting its usefulness as a prebiotic for improving gut health and combating obesity.

Dietary supplementation with indigestible carbohydrates is known to improve the gut environment and prevent obesity and inflammatory diseases by modulating the gut microbiota. In previous work, we established a method for the production of resistant starch (RS)-enriched high-amylose rice (R-HAR) using citric acid. The present study aimed to evaluate changes in structural characteristics during digestion of R-HAR and its effects on the gut health.

Gellan gum (GG) is an anionic polysaccharide used as an additive in the food industry. However, the effect of GG on gut microbiota regulation and nonalcoholic fatty liver disease (NAFLD) has not yet been investigated. In vitro fermentation experiments have demonstrated that GG promoted the growth of probiotic strains such as Lactiplantibacillus rhamnosus and Bifidobacterium bifidum, producing metabolites beneficial to gut health.

Background And Aims: Excessive intake of advanced glycation end products (AGEs), which are formed in foods cooked at high temperatures for long periods of time, has negative health effects, such as inflammatory responses and oxidative stress. N-(Carboxymethyl)lysine (CML) is one of the major dietary AGEs. Given their generally recognized as safe status and probiotic functionalities, lactic acid bacteria may be ideal supplements for blocking intestinal absorption of food toxicants.

Dietary habits and gut microbiota play an essential role in non-alcoholic fatty liver disease (NAFLD) and related factors such as insulin resistance and de novo lipogenesis. In this study, we investigated the protective effects of CBA7346, isolated from the gut of healthy Koreans, on mice with high-fat diet (HFD)-induced NAFLD. Administration of CBA7346 reduced body and liver weight gain, serum alanine aminotransferase and aspartate aminotransferase levels, liver steatosis, and liver triglyceride levels in mice on an HFD; the strain also decreased homeostatic model assessment for insulin resistance values, as well as serum cholesterol, triglyceride, lipopolysaccharide, leptin, and adiponectin levels in mice on an HFD.

Radish (Raphanus sativus) greens are commonly used as a vegetable in Korea; however, their anti-obesity effect has not been reported yet. We prepared the polysaccharide fraction of radish greens (PRG) and assessed its anti-obesity activity in high fat diet (HFD)-induced obese C57BL/6J mice. Supplementation with 4 mg/kg PRG reduced weight gain and body fat percentage, and regulated serum biomarkers against HFD-induced obesity.

Recent studies report that microbiota in the human intestine play an important role in host health and that both long- and short-term diets influence gut microbiota. These findings have fueled interest in the potential of food to promote health by shaping the intestinal microbiota. Despite the fact that large populations in Asia consume high quantities of carbohydrates, such diets have been ignored in comparison to the attention received by Western diets containing high quantities of fat and animal protein.
