Summary: A novel sepsis pig model is created by modifying the surgical strategy of cecal ligation and puncture (CLP), which for the first time recapitulates the whole course of sepsis in humans. Increased levels of ZBED6 in skeletal muscle are shown in this model and sepsis patients, and protection against sepsis-induced muscle wasting is demonstrated in ZBED6-deficient pigs. The direct target of ZBED6 is revealed to be DOCK3, and septic ZBED6-deficient pigs show increased DOCK3 expression in skeletal muscle and myocytes, activating the RAC1/PI3K/AKT pathway and protecting against sepsis-induced muscle wasting.

Summary: This study explores the anti-muscle atrophy effect of Achyranthes bidentata Blume (AB) and identifies the signaling pathways involved. It is found that the saponin extract of AB has a protective effect on muscle atrophy by increasing muscle fiber diameter and proportion of slow muscle fibers, possibly through activation of the PI3K/Akt pathway.

Summary: Elderly male patients are prone to developing osteoporosis and sarcopenia, but there are few available treatments for sarcopenia in men. This study investigated the effects of eldecalcitol on androgen-deficient male mice and found that it increased bone mass, strength, and muscle fiber levels in the mice. Eldecalcitol could be a potential treatment for sarcopenia and osteoporosis in male patients.

Summary: Adding Spirulina hydrolysates (SPH) to the cell culture medium can promote the differentiation of C2C12 myoblasts and inhibit Dexamethasone (DEX)-induced myotube atrophy. This is achieved by regulating the expression of muscle atrophy-related factors and regulating the FoxO3a transcription factor.

Summary: This study reveals the effects of Ginsenoside Rg5 on muscle differentiation, growth, and prevention of muscle atrophy. Rg5 promotes myogenesis and hypertrophy by activating p38MAPK and Akt/mTOR signaling pathways. This research suggests that Rg5 has potential therapeutic applications in muscle weakness and atrophy.

Summary: MOTS-c, a mitochondrial-derived peptide, reduces high-fat-diet-induced muscle atrophy signaling by decreasing myostatin expression. The CK2-PTEN-mTORC2-AKT-FOXO1 pathways play key roles in MOTS-c action on myostatin expression.

Summary: In this study, a drug screening model was established using machine learning to predict the potential active compound ingenol for the treatment of radiation- and chemotherapy-induced thrombocytopenia. In vitro experiments and animal models were used to demonstrate that ingenol promoted megakaryocyte differentiation and platelet production. The activation of the PI3K/Akt signaling pathway was found to be involved in ingenol-induced megakaryocyte differentiation.

Summary: This study revealed that supplementation with butyrate can improve serum butyrate levels in DN patients and enhance intestinal barrier function in db/db mice, alleviating muscle atrophy. In HG/LPS-exposed C2C12 cells, butyrate activates the FFA2 receptor-mediated PI3K/Akt/mTOR pathway, suppressing oxidative stress and autophagy.

Summary: Obesity is a growing disorder that damages patients' quality of life and increases healthcare costs. Developing safe and innovative prevention strategies and treatments for obesity is crucial. The pathophysiology of obesity is complex and involves multiple signaling pathways, including the PI3K/AKT pathway, which plays a critical role in metabolic homeostasis. Natural compounds have been shown to target the PI3K/AKT signaling pathway and have potential for managing obesity. This paper evaluates the druggability of PI3K as a target and suggests perspectives on using natural compounds to modulate the PI3K/AKT pathway for obesity management.

Summary: This study investigated the effects of monotropein (MON) on improving dexamethasone (DEX)-induced muscle atrophy in mice and C2C12 mouse skeletal muscle cells. MON improved muscle atrophy by regulating catabolic states via the AKT/mTOR/FOXO3a signaling pathways and enhanced muscle function by increasing muscle mass and strength in mice.

Summary: This study explored the mechanism of action of ginseng polysaccharides (GP) in immune liver injury and investigated its potential therapeutic effect on immune-related liver diseases. The results showed that low molecular weight ginseng polysaccharides (LGP) can improve cell viability, suppress the release of inflammatory factors, and inhibit hepatocyte apoptosis. Additionally, LGP treats autoimmune hepatitis by inhibiting the activation of the PI3K/AKT and TLRs/NF-kappa B signaling pathways.

Summary: Protein degradation is essential for cellular integrity, with autophagy and the UPS being the main systems responsible for protein breakdown. Recent studies show that even complex protein structures can be efficiently degraded in vivo, with AAA-ATPases playing a crucial role in the disassembly process.
