Tetragonia tetragonioides extract prevented high-fat diet-induced obesity and changed hepatic and adipose transcriptomic signatures in C57BL/6J male mice.

Obesity, often driven by high-fat diets (HFD), is a major global health issue, necessitating effective preventive measures. Tetragonia tetragonoides, a plant with known medicinal properties, has not been extensively studied for its effects on HFD-induced obesity and related genetic changes in mice. This study explores the impact of Tetragonia tetragonoides extract (TTE; 300 mg/kg) on obesity-related traits in C57BL/6J male mice, with a focus on transcriptomic changes in the liver and white adipose tissue (WAT).

UG0712, A Ginsenoside Complex, Improved Endurance Performance and Changed Hepatic and Muscular Transcriptomic Signatures in C57BL/6N Male Mice.

Ginsenosides, active compounds derived from Panax ginseng, exhibit promising potential in enhancing physical performance. This study investigates the impact of UG0712 (UG), a novel ginsenoside compound, on endurance capacity, body weight, organ weights, blood parameters, and specific transcriptomic changes in liver and muscle tissues using a C57BL/6N mouse model. The mice received UGs orally at three doses: UG50 (50 mg/kg), UG100 (100 mg/kg), and UG200 (200 mg/kg) for a specified duration.

An inquiry into the radial patterning of root hair cell distribution in eudicots.

The root epidermis of tracheophytes consists of hair-forming cells (HCs) and nonhair cells (NCs). The HC distribution pattern is classified into three types: random (Type I), vertically alternating (Type II), and radial (Type III). Type III is found only in core eudicots and is known to be position-dependent in superrosids with HCs positioned between two underlying cortical cells.

A dose-dependent bimodal switch by homologous Aux/IAA transcriptional repressors.

Combinatorial interactions between different regulators diversify and enrich the chance of transcriptional regulation in eukaryotic cells. However, a dose-dependent functional switch of homologous transcriptional repressors has rarely been reported. Here, we show that SHY2, an auxin/indole-3-acetic acid (Aux/IAA) repressor, exhibits a dose-dependent bimodal role in auxin-sensitive root-hair growth and gene transcription in Arabidopsis, whereas other Aux/IAA homologs consistently repress the auxin responses.

Calcium-dependent protein kinase 29 modulates PIN-FORMED polarity and Arabidopsis development via its own phosphorylation code.

PIN-FORMED (PIN)-mediated polar auxin transport (PAT) is involved in key developmental processes in plants. Various internal and external cues influence plant development via the modulation of intracellular PIN polarity and, thus, the direction of PAT, but the mechanisms underlying these processes remain largely unknown. PIN proteins harbor a hydrophilic loop (HL) that has important regulatory functions; here, we used the HL as bait in protein pulldown screening for modulators of intracellular PIN trafficking in Arabidopsis thaliana.

The DME demethylase regulates sporophyte gene expression, cell proliferation, differentiation, and meristem resurrection.

The flowering plant life cycle consists of alternating haploid (gametophyte) and diploid (sporophyte) generations, where the sporophytic generation begins with fertilization of haploid gametes. In , genome-wide DNA demethylation is required for normal development, catalyzed by the DEMETER (DME) DNA demethylase in the gamete companion cells of male and female gametophytes. In the sporophyte, postembryonic growth and development are largely dependent on the activity of numerous stem cell niches, or meristems.

In Vitro and In Vivo Inhibitory Effect of Citrus Junos Tanaka Peel Extract against Oxidative Stress-Induced Apoptotic Death of Lung Cells.

Various stresses derived from both internal and external oxidative environments lead to the excessive production of reactive oxygen species (ROS) causing progressive intracellular oxidative damage and ultimately cell death. The objective of this study was to evaluate the protective effects of Tanaka peel extract (CE) against oxidative-stress induced the apoptosis of lung cells and the associated mechanisms of action using in vitro and in vivo models. The protective effect of CE was evaluated in vitro in NCI-H460 human lung cells exposed to pro-oxidant HO.

Intracellularly Localized PIN-FORMED8 Promotes Lateral Root Emergence in .

PIN-FORMED (PIN) auxin efflux carriers with a long central hydrophilic loop (long PINs) have been implicated in organogenesis. However, the role of short hydrophilic loop PINs (short PINs) in organogenesis is largely unknown. In this study, we investigated the role of a short PIN, PIN8, in lateral root (LR) development in .

Utilization of Pectinase Cocktail and High Hydrostatic Pressure for the Production of Aged Black Garlic Juice with Improved Nutritional Value.

In comparison with raw garlic, aged black garlic has been shown to display multiple pharmacological activities. We recently reported that pretreatment of pectinase cocktail with high hydrostatic pressure (HHP) before the process of aging garlic juice improves its antidiabetic activity and increases -allylcysteine (SAC) content. Thus, this study was designed to investigate the influence of pectinase cocktail with HHP on the quality of aged black garlic juice formation and to identify the optimal manufacturing conditions.

Root hairs enhance Arabidopsis seedling survival upon soil disruption.

Root hairs form a substantial portion of the root surface area. Compared with their nutritional function, the physical function of root hairs has been poorly characterised. This study investigates the physical role of root hairs of Arabidopsis thaliana seedlings in interaction of the root with water and soil and in plant survival upon soil disruption.

Explosively Puffed Ginseng Ameliorates Ionizing Radiation-Induced Injury of Colon by Decreasing Oxidative Stress-Related Apoptotic Cell Execution in Mice.

Although radiation therapy (RT) is a feasible treatment approach for early colorectal cancer, RT is considerably toxic to normal tissues due to the increased reactive oxygen species production, which can induce tissue damage. Ginseng, a natural antioxidant agent, exhibits the protective effects against ionizing radiation (IR)-induced damage in and models. The explosive puffing of ginseng has been investigated as a process to improve the efficacy of ginseng due to the resulting physicochemical changes in its functional components.

Ameliorative effect of black ginseng extract against oxidative stress-induced cellular damages in mouse hepatocytes.

Background: Oxidative stress induces the production of reactive oxygen species (ROS), which play important causative roles in various pathological conditions. Black ginseng (BG), a type of steam-processed ginseng, has drawn significant attention due to its biological activity, and is more potent than white ginseng (WG) or red ginseng (RG).

Methods: We evaluated the protective effects of BG extract (BGE) against oxidative stress-induced cellular damage, in comparison with WG extract (WGE) and RG extract (RGE) in a cell culture model.

Developmental Programming of Thermonastic Leaf Movement.

Plants exhibit diverse polar behaviors in response to directional and nondirectional environmental signals, termed tropic and nastic movements, respectively. The ways in which plants incorporate directional information into tropic behaviors is well understood, but it is less well understood how nondirectional stimuli, such as ambient temperatures, specify the polarity of nastic behaviors. Here, we demonstrate that a developmentally programmed polarity of auxin flow underlies thermo-induced leaf hyponasty in Arabidopsis ().

LB-9, Novel Probiotic Lactic Acid Bacteria, Ameliorates Dextran Sodium Sulfate-Induced Colitis in Mice by Inhibiting TNF-α-Mediated Apoptosis of Intestinal Epithelial Cells.

Inflammatory bowel disease (IBD), including ulcerative colitis (UC) and Crohn's disease, is a group of chronic and relapsing inflammatory conditions within the gastrointestinal tract. An increase in intestinal epithelial cell (IEC) apoptosis is a major characteristic of UC. Tumor necrosis factor-α (TNF-α) plays an essential role in the regulation of apoptosis.

Effects of Orally-Administered subsp. Strain BB12 on Dextran Sodium Sulfate-Induced Colitis in Mice.

Inflammatory bowel disease, including Crohn's disease and ulcerative colitis (UC), is a chronically relapsing inflammatory disorder of the gastrointestinal tract. Intestinal epithelial cells (IECs) constitute barrier surfaces and play a critical role in maintaining gut health. Dysregulated immune responses and destruction of IECs disrupt intestinal balance.

Lactobacillus plantarum LRCC 5273 isolated from Kimchi ameliorates diet-induced hypercholesterolemia in C57BL/6 mice.

This study was designed to select potent cholesterol-lowering probiotic strains on HepG2 cell and investigate the effect of selected strain, Lactobacillus plantarum LRCC 5273 and LRCC 5279 in hypercholesterolemic mice. In the results, LP5273 group showed significantly reduced total and LDL cholesterol compared to HCD group. In addition to significantly up-regulated hepatic mRNA expression of LXR-α and CYP7A1, intestinal LXR-α and ABCG5 were significantly up-regulated in LP5273 group.

Two TPL-Binding Motifs of ARF2 Are Involved in Repression of Auxin Responses.

Auxin signaling is finalized by activator auxin response factors (aARFs) that are released from Auxin/Indole-3-Acetic Acid (Aux/IAA) repressors and directly activate auxin-responsive genes. However, it remains to be answered how repressor ARFs (rARFs) exert their repression function. In this study, we assessed the molecular and biological functions of two putative co-repressor-binding motifs (EAR and RLFGI) of ARF2 (a rARF) in .

Changes in hepatic gene expression and serum metabolites after oral administration of overdosed vitamin-E-loaded nanoemulsion in rats.

Vitamin-E-loaded nanoemulsion (Vit E-NE) was produced, and the effects of repeated oral administration of Vit E-NE (2 g/kg/day) for five days on hepatic gene expression and serum metabolites were investigated in rats. The mean particle diameter and zeta potential of Vit E-NE was 112 nm and 56 mV, respectively. Vit E-NE administered rats showed significantly higher triglyceride content than of standard diet (control) or Vit E control emulsion (Vit E-CE) group but no toxicity symptoms were found in blood biochemical analysis.

Effects of extracts prepared at different steaming times on thermogenesis in rats.

Background: (PG) has a long history of use in Asian medicine because of its multiple pharmacological activities. It has been considered that PG in a type of white ginseng may induce undesirable thermogenic effects, but not in a type of red ginseng. However, there is a lack of evidence about the correlation between ginsenoside and thermogenesis.

Molecular link between auxin and ROS-mediated polar growth.

Root hair polar growth is endogenously controlled by auxin and sustained by oscillating levels of reactive oxygen species (ROS). These cells extend several hundred-fold their original size toward signals important for plant survival. Although their final cell size is of fundamental importance, the molecular mechanisms that control it remain largely unknown.
