Summary: This study found that FB1 contamination has a toxic effect on the intestine and disrupts its barrier function. FB1 also leads to excessive production of cytokines, further damaging the intestinal immune barrier. By inhibiting the expression of CerS2, FB1 induces endoplasmic reticulum stress, resulting in the destruction of the intestinal barrier. However, this damage can be restored by overexpression of CerS2 or the use of an ER stress inhibitor.

Summary: The aim of this study is to investigate the role of RYR2 in cardiomyocyte maturation. The researchers used genetic editing techniques to knockout RYR2 and found that its depletion led to structural and transcriptional defects in cardiomyocytes, along with activation of ER stress pathways. The defects in RYR2-depleted cardiomyocytes were partially rescued by an ER stress alleviator.

Summary: This study reveals the involvement of RHD3 in the ER-phagy process under ER stress and the hyposensitivity of the rhd3 mutant to ER and salt stress. The increased association of RHD3 with ATG8e-marked autophagosomes and its breakdown under ER stress are demonstrated. The physical interaction between RHD3 and ATG8 is also enhanced under ER stress.

Summary: The regulation of autophagy in plants is still poorly understood, but recent research has identified the role of ufmylation components in maintaining ER homeostasis under salt stress. The expression of Ufm1-conjugating enzyme and Ufm1 protein increases in response to salt stress, indicating their involvement in regulating reticulophagy in plants.

Summary: This study found that serum level of the endoplasmic reticulum (ER) chaperone, protein disulfide isomerase family A, member 4 (PDIA4), is associated with type 2 diabetes mellitus (T2DM), insulin sensitivity, and obesity. Higher serum PDIA4 concentration is significantly associated with an increased risk of T2DM. These findings provide new insights into the relationship between ER stress, T2DM, and metabolic dysfunction, and suggest that PDIA4 may be a potential therapeutic target for T2DM.

Summary: Modern lifestyles, lack of physical activity, poor nutrition, and high levels of saturated free fatty acids in obese individuals contribute to the increasing prevalence of obesity and type 2 diabetes. The study suggests that transient NOX2-dependent H2O2 production may be a key factor in early palmitate-induced lipotoxic effects.

Summary: Oxidative stress and inflammation are important factors in the development of liver diseases. NRF2 plays a crucial role in protecting against oxidative damage by regulating the expression of cytoprotective genes. COX-2, in addition to its role in inflammation, has a beneficial effect in reducing inflammation and oxidative stress in liver diseases, and it works together with NRF2 to provide a hepatoprotective effect.

Summary: Chemotherapy is the main treatment for advanced or unresectable hepatocellular carcinoma (HCC), but chemoresistance is a significant challenge. Exogenous ceramide has anticancer effects, but recent studies have shown ceramide resistance. diTFPP is a novel compound that can increase the sensitivity of HCC cells to ceramide treatment. This study clarifies the mechanism by which diTFPP enhances the response to C-2-ceramide-induced stresses, providing insights into ceramide resistance and aiding in the development of adjuvants for ceramide-based cancer therapeutics.

Summary: This study reveals that Fusobacterium nucleatum promotes self-renewal of colorectal cancer stem-like cells (CCSCs) and acquisition of CCSC features in non-CCSCs by manipulating cellular lipid accumulation. F. nucleatum decreases lipid accumulation in CCSCs by enhancing fatty acid oxidation, while increasing lipid accumulation in non-CCSCs by promoting fatty acid formation. Lipid droplets play a crucial role in this process, facilitating the degradation of the cell fate regulator Numb and activating Notch signaling, leading to the gain of stem-like cell features.

Summary: Dietary and symbiotic bacteria have a significant impact on metazoan lipid metabolism, but the mechanisms by which bacteria influence lipid storage in their host are still unknown. This study used Caenorhabditis elegans as a model organism to investigate the interaction between gut microbiota and the host. The results showed that feeding C. elegans with Stenotrophomonas maltophilia (S. maltophilia) bacteria retarded growth and promoted excessive neutral lipid storage. Gene expression analysis revealed a lipogenic response induced by dietary S. maltophilia. Furthermore, it was observed that excess neutral lipid was stored in expanded lipid droplets due to enhanced endoplasmic reticulum (ER)-lipid droplet interactions. The study also identified a gene mutation in C. elegans that conferred resistance to S. maltophilia. This work provides a new model for understanding how microbes regulate metazoan physiology.

Summary: Photodynamic inactivation (PDI) is a promising approach to combat multi-drug resistance. However, the short half-life of O-1(2) and the photobleaching of the photosensitizer (PS) limit its efficiency. Researchers have developed a ROS conversion strategy that converts O-1(2) to hydrogen peroxide (H2O2), leading to an extended half-life of ROS and reduced photobleaching. This reinforced photodynamic model system improves antibacterial efficiency and accelerates wound healing.

Summary: This paper aims to fill the gap in existing research on the internal causes of inter-regional differences in carbon emission efficiency. By accurately measuring China's dynamic carbon emission efficiency of industrial energy, the study found that the efficiency is increasing and overall energy efficiency is at a high level. Long-term gaps are mainly attributed to regional differences and transvariation intensity. The study also highlights the importance of efficiency change and technological change in improving carbon emission efficiency.

Summary: Increased consumption of high-fat low-fiber foods is associated with the development of metabolic syndromes. Fermentable dietary fiber, such as inulin, can alleviate metabolic abnormalities. This study systematically investigated the effect of inulin on mice with metabolic disorders induced by short-term and long-term high-fat feeding. The results showed that inulin reduced body weight, improved glucose intolerance, and alleviated hepatic steatosis in both groups of mice, suggesting a potential mechanism mediated through the modulation of gut microbiota.

Summary: A new type of quaternized lignin-functionalized poly(hexamethylene biguanide) hydrochloride (QL-PHMB-PAM) hydrogel was developed as a multifunctional dressing material for infected wound repair. This hydrogel exhibited strong adhesiveness and antioxidative properties, and showed high efficiency and long-term antibacterial activity against pathogens such as Staphylococcus aureus and Escherichia coli. In vivo experiments demonstrated that this hydrogel accelerated the healing of infected wounds by promoting blood vessel and hair follicle reconstruction, making it a promising alternative wound dressing material.

Summary: Good's buffers have been widely used in cell/organ culture as biocompatible pH stabilizers. However, the emergence of adverse effects such as cellular uptake, autophagic activation, and cytotoxicity under light exposure raises concerns over its biocompatibility. Riboflavin in the cell culture medium produces reactive oxygen species (ROS) under light exposure, causing severe toxicity and disruption of normal cell functions. Zwitterionic betaines have been identified as a new generation of biocompatible pH buffers that do not exhibit these adverse effects.
