Abstract
Low temperature is a common stress source for the poultry industry in the north of China. However, the low energy consuming and economical way to reduce the negative effects from cold stress is still limited. Therefore, the aim of this study was to investigate the effect of rutin on intestinal barrier in mice under low temperature. The cold stress model was established at 4°C for 3 h each day and the experiment lasted for 21 days. Forty Balb/c mice were randomly divided into four treatments: CON, normal temperature with the basal diet; RUT, normal temperature with the basal diet +150 mg/kg body weight (BW) of rutin; CS, mice under cold stress with basal diet; CR, 150 mg/kg of BW rutin under cold stress. Rutin supplementation significantly increased the ileum villus-to-crypt ratio compared with these non-supplemented treatments. Rutin attenuated the hypothermia induced morphological damage in the ileum. In addition, rutin improved the antioxidant capacity of mice under cold stress. Rutin supplementation significantly increased the trypsin activity and inhibited the lipase in cold stressed mice. Rutin supplementation significantly inhibited the production of inflammatory factors induced by cold stress. Rutin induced the inhibition of TLR4 and NF-кB, thereby reducing the expression of inflammation-related genes. In addition, rutin improved the reduction of the intestinal claudin-1 and occludin expression in those mice in the cold stress (P < .05) and improved the intestinal ZO-1 expression in cold stressed mice. Finally, rutin alleviated the dysregulation of intestinal microflora in the mice under cold stress.

Extracellular CIRP induces abnormal activation of fibroblast-like synoviocytes from patients with RA via the TLR4-mediated HDAC3 pathways. Int Immunopharmacol 2024; 128:111525. [PMID: 38218010 DOI: 10.1016/j.intimp.2024.111525] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/05/2023] [Revised: 01/04/2024] [Accepted: 01/07/2024] [Indexed: 01/15/2024]
Abstract
The development of rheumatoid arthritis (RA) is closely related to the excessive activation of fibroblast-like synoviocytes (FLSs), which are regulated by a variety of endogenous proinflammatory molecules. Extracellular cold-inducible RNA-binding protein (CIRP), as a novel endogenous proinflammatory molecule, plays an important role in inflammatory diseases. More importantly, the synovial concentration of CIRP in patients with RA was significantly higher than that in patients with osteoarthritis (OA). Thus, this study aimed to investigate the role of extracellular CIRP in the abnormal activation of RA-FLSs and its related mechanisms. Our study showed that extracellular CIRP induced proliferation, migration and invasion of RA-FLSs, increased the expression of N-cadherin and MMP-3, and promoted the release of IL-1β and IL-33. However, blocking of extracellular CIRP with C23 inhibited CIRP-induced abnormal activation of RA-FLSs and alleviated the arthritis severity in AA rats. Accumulating evidence suggests that the activity and proinflammatory effects of CIRP are mediated through Toll-like receptor 4 (TLR4). Further studies demonstrated that the TLR4 knockdown inhibited CIRP-induced abnormal activation, and histone deacetylase 3 (HDAC3) expression in RA-FLSs. In addition, we found that HDAC3 knockdown and the specific inhibitor RGFP966 significantly suppressed CIRP-induced abnormal activation of RA-FLSs. We further found that treatment with HDAC3 specific inhibitor effectively alleviated the severity of arthritis in AA rats. Taken together, these findings indicate that extracellular CIRP induces abnormal activation of RA-FLSs via the TLR4-mediated HDAC3 pathways.

Biomed Pharmacother 2024; 170:115984.

Abstract
In recent years, the incidence of intestinal ischemia-reperfusion injury (II/RI), inflammatory bowel disease (IBD), and colorectal cancer (CRC) has been gradually increasing, posing significant threats to human health. Autophagy and endoplasmic reticulum stress (ERS) play important roles in II/RI. Damage caused by ischemia and cellular stress can activate ERS, which in turn initiates autophagy to clear damaged organelles and abnormal proteins, thereby alleviating ERS and maintaining the intestinal environment. In IBD, chronic inflammation damages intestinal tissues and activates autophagy and ERS. Autophagy is initiated by upregulating ATG genes and downregulating factors that inhibit autophagy, thereby clearing abnormal proteins, damaged organelles, and bacteria. Simultaneously, persistent inflammatory stimulation can also trigger ERS, leading to protein imbalance and abnormal folding in the ER lumen. The activation of ERS can maintain cellular homeostasis by initiating the autophagy process, thereby reducing inflammatory responses and cell apoptosis in the intestine. In CRC, excessive cell proliferation and protein synthesis lead to increased ERS. The activation of ERS, regulated by signaling pathways such as IRE1α and PERK, can initiate autophagy to clear abnormal proteins and damaged organelles, thereby reducing the negative effects of ERS. It can be seen that autophagy and ERS play a crucial regulatory role in the development of intestinal diseases. Therefore, the progress in targeted therapy for intestinal diseases based on autophagy and ERS provides novel strategies for managing intestinal diseases. In this paper, we review the advances in regulation of autophagy and ERS in intestinal diseases, emphasizing the potential molecular mechanisms for therapeutic applications.
