Summary: Long-term high-fat diet causes insulin resistance and impairs insulin clearance, with a decrease in renal IDE expression. The PPAR gamma pathway is involved in the inhibition of IDE expression by palmitic acid. Rosiglitazone improves insulin clearance and insulin resistance and increases renal IDE expression in HFD fed-mice.

Summary: The primary cilium is a cell organelle located at the cell surface, which plays a role in sensing external stimuli and mediating cell-to-cell communication. Recent studies have uncovered the emerging roles of primary cilium and cilia-mediated signaling pathways in the regulation of pancreatic beta- and alpha-cell functions and glucose homeostasis.

Summary: This study found that empagliflozin (EMPA) has a protective effect against insulin resistance (IR) induced by junk food. EMPA can improve IR through various mechanisms, including reducing obesity, improving glucose metabolism, alleviating liver and kidney damage, and reducing inflammation. Additionally, the combination of EMPA and metformin (MET) has a synergistic effect in improving dyslipidemia, oxidative stress, and kidney function.

Summary: There are still many important unresolved questions in the field of IDE, such as how IDE interacts with extracellular substrates, its localization and functional roles within the cell, and how it avoids getting clogged and losing activity. The author provides personal insights and experimental strategies to address these challenges, aiming to advance the research on the physiology and pathophysiology of IDE with the development of new technologies and specific reagents.

Summary: Insulin-degrading enzyme (IDE) is a multifunctional protease that has been implicated in metabolic and neuronal diseases. Recent studies have also shown IDE's overexpression in different cancers, suggesting its potential as a target in cancer therapeutics. Further research is needed to fully understand IDE's role in cancer development, but pharmacological modulation of IDE has shown promising results in cancer models.

Summary: Insulin-degrading enzyme (IDE) is a key enzyme involved in the degradation of insulin and other amyloidogenic peptides. Its role in curing diabetes and Alzheimer's disease has long been anticipated, but its exact role in degrading amyloidogenic proteins is not yet clearly defined. Recently, novel non-proteolytic functions of IDE have been proposed. A better understanding of the structure-function relationship of IDE may help solve existing paradoxes and lead to new therapeutic approaches.

Summary: The endocrine pancreas is influenced by GSPE treatment, with continued effects on glucagon and increased GLP-1 response and receptor expression in the pancreas. When GSPE treatment is given every two weeks, the behavior of the endocrine pancreas changes, with glucagon being a more sensitive parameter to GSPE treatments, dependent on GLP-1 functionality.

Summary: The study suggests that IDE plays a crucial role in regulating postprandial insulin clearance and liver metabolic resilience. Dysfunctional IDE regulation directly impairs postprandial hepatic glucose disposal and increases susceptibility to dysmetabolic conditions.

Summary: Bitter taste receptor hTAS2R5 has a unique functional specificity in humans and its closest functional homolog in mouse is mTas2r144, which is phylogenetically distant from hTAS2R5. There is no consensus about the role of hTAS2R5. Comparison with other species' bitter taste receptors reveals that hTAS2R5 has no ortholog in pig, mouse, or rat genomes.

Summary: The study aimed to evaluate the protective effects of short-term GSPE pre-treatment in the hippocampus of rats against prolonged feeding with cafeteria diet. Results showed that GSPE was able to protect against cellular damage through AKT activation and promote mitochondrial function maintenance. Additionally, GSPE decreased inflammatory activation and reduced reactivity of astrocytes.

Summary: This study aimed to determine whether adipocytokines and microbiota-derived metabolites can be used as predictive biomarkers for metabolic improvement post-surgery in women with clinically severe obesity. The results showed that levels of certain cytokines and microbiota-derived metabolites changed after surgery, correlating with improvements in glucose, insulin, and lipid levels.

Summary: This study compared the effects of insect and almond preloads on appetite and food intake. The results showed that the insect preload increased protein intake without increasing total energy intake, and had a lower impact on sleepiness and tiredness compared to the almond preload. Insect-derived protein could be a suitable and safe ingredient for snacks intended for elderly or infirm patients.

Summary: Over thousands of years of evolution, animals have developed various ways to protect themselves. The bitter taste receptor 39 (TAS2R39) is present not only in the oral cavity but also in the gastrointestinal tract, respiratory system, nervous system, and reproductive system. It plays a role in sensing the bitter components of food and protecting the organism from harmful compounds. Further research is needed to determine its precise role in these and other tissues.

Summary: This study examined the effects of a Cafeteria diet on the intestines of rats and found that it caused adaptive morphologic and functional changes. Additionally, it was discovered that supplementation with grape seed proanthocyanidin extract (GSPE) partially reversed the intestinal morphological changes induced by the high fat/sucrose diet.

Summary: This study found that acutely ingesting insect Alphitobius diaperinus protein increases food intake in rats and modifies the ex vivo enterohormone secretory profile differently than beef or almond proteins. However, these effects cannot be maintained for a longer period. The results suggest that consuming insect protein increases food intake by reducing ghrelin secretion in the small intestine.

Summary: Adipose tissue secretes leptin to modulate energy homeostasis, and this process is regulated by succinate through its receptor SUCNR1. Deletion of Sucnr1 in adipocytes affects metabolic health based on nutritional status. Activation of SUCNR1 controls leptin expression via the circadian clock in an AMPK/JNK-C/EBPa-dependent manner. Succinate/SUCNR1 axis serves as a metabolite-sensing pathway mediating nutrient-related leptin dynamics to maintain whole-body homeostasis.

Summary: The impact of healthy aging on society has generated interest in studying aging mechanisms, yet the effects of this process on the gastrointestinal tract are not fully understood. Controversial results have been found regarding changes in the enteroendocrine system along the gastrointestinal tract. Grape seed proanthocyanidin extracts (GSPE) have been shown to protect against aging-related pathologies. In this study, researchers hypothesized that GSPE pre-treatment could prevent aging processes affecting the enteroendocrine system. By treating aged rats with GSPE, they found that the expression of enterohormones in the colon was preserved, suggesting that GSPE may be effective in preventing decreased enterohormone expression induced by aging.

Summary: Diet-induced changes in the intestinal barrier and gut microbiota lead to the translocation of lipopolysaccharide (LPS) from the lumen to the lamina propria through different mechanisms, resulting in metabolic endotoxemia. The study evaluated the role of grape seed proanthocyanidin extract (GSPE) in modulating LPS translocation and the underlying mechanisms using in vitro and in vivo experiments. GSPE was found to regulate intestinal permeability by modulating receptor-mediated endocytosis and the interaction between gut microbiota and the endocannabinoid system through epigenetic mechanisms. These findings suggest that GSPE can improve intestinal dysfunction and metabolic endotoxemia caused by a high-fat diet.

Summary: In this study, we investigated the effects of gastrointestinal digested black soldier fly (BSF) prepupae on GLP-1 and DPP-IV. The results showed that these digested proteins have a high ability to stimulate GLP-1 secretion and inhibit DPP-IV enzyme activity in human cells. Furthermore, optimizing diets or fermentation processes did not improve the efficacy of the answer. The bioactivity of BSF on glycaemic control systems after simulated digestion makes it even more promising as a suitable edible insect for human consumption.

Summary: This study found that grape seed derived procyanidins (GSPE) have different effects on enterohormone secretion and intestinal sizes in aged rats, compared to young rats. The cafeteria diet affects the duodenum and colon differently in aged rats, while procyanidins have a larger effect on the ileum.
