Abstract
As bacteria synthesize nutrients primarily in the cecum, coprophagy is indispensable for supplying rabbits with essential nutrients. Recent research has demonstrated its pivotal role in maintaining intestinal microbiota homeostasis and immune regulation in rabbits, although the specific mechanism remains unknown. Here, we used coprophagy prevention (CP) to investigate the effects of coprophagy on the cecum homeostasis and microbiota in New Zealand white rabbits. Furthermore, whether supplementation of Clostridium butyricum (C. butyricum) may alleviate the cecum inflammation and apoptosis caused by CP was also explored. Four groups were randomly assigned: control (Con), sham-coprophagy prevention (SCP), coprophagy prevention (CP), and CP and C. butyricum addition (CPCB). Compared to Con and SCP, CP augmented cecum inflammation and apoptosis, as well as bacterial adhesion to the cecal epithelial mucosa, while decreasing the expression of tight junction proteins (ZO-1, occluding, and claudin-1). The relative abundance of short-chain fatty acids (SCFAs)-producing bacteria was significantly decreased in the CP group. Inversely, there was an increase in the Firmicutes/Bacteroidetes ratio and the relative abundance of Christensenellaceae_R-7_group. Additionally, CP increased the levels of Flagellin, IFN-γ, TNF-a, and IL-1β in cecum contents and promoted the expression of TLR5/MyD88/NF-κB pathway in cecum tissues. However, the CPCB group showed significant improvements in all parameters compared to the CP group. Dietary C. butyricum supplementation significantly increased the production of SCFAs, particularly butyric acid, triggering anti-inflammatory, tissue repairing, and barrier-protective responses. Notably, CPCB effectively mitigated CP-induced apoptosis and inflammation. In summary, CP disrupts the cecum epithelial barrier and induces inflammation in New Zealand white rabbits, but these effects can be alleviated by C. butyricum supplementation. This process appears to be largely associated with the TLR5/MyD88/NF-κB signaling pathway.

Clostridium butyricum Ameliorates the Effect of Coprophagy Prevention on Hepatic Lipid Synthesis in Rabbits via the Gut-Liver Axis. Int J Mol Sci 2023; 24:17554. [PMID: 38139382 PMCID: PMC10744194 DOI: 10.3390/ijms242417554] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2023] [Revised: 12/07/2023] [Accepted: 12/12/2023] [Indexed: 12/24/2023] Open
Abstract
Coprophagy prevention (CP) affects the growth performance, hepatic lipid synthesis, and gut microbiota in rabbits. Supplementation with Clostridium butyricum (C. butyricum, Strain number: CCTCC M 2019962) has been found to improve growth performance in rabbits. However, it remains unknown whether C. butyricum can ameliorate the effects of CP on hepatic lipid synthesis and the underlying mechanisms are yet to be elucidated. Therefore, this study aimed to investigate the impact of CP on hepatic lipid synthesis and the underlying mechanism based on the gut-liver axis. The findings revealed that supplementation with C. butyricum could reverse CP-related growth performance, lipid accumulation, bile acid synthesis, and inflammation. Furthermore, C. butyricum exerted protective effects on the gut by preserving intestinal barrier integrity and modulating gut microbiota composition; these factors may represent potential mechanisms through which C. butyricum improves CP-related outcomes. Specifically, C. butyricum reshaped the microbiota by increasing butyric acid levels, thereby maintaining secondary bile acid (deoxycholic acid, chenodeoxycholic acid) balance and attenuating the inhibitory effects of the FXR/SHP pathway on lipid synthesis (SREBP1c/ApoA1). Moreover, the activation of butyrate/GPR43pathway by C. butyricum reduced damage to the intestinal barrier (ZO-1/Occludin/Claudin1) and restored the gut immune microenvironment in CP rabbits. In summary, supplementation with C. butyricum can alleviate the adverse effects of CP on growth performance and hepatic lipid synthesis by modulating the gut-liver axis.

Coprophagy Prevention Affects the Reproductive Performance in New Zealand White Rabbits Is Mediated through Nox4-ROS-NFκB Pathway. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2022.

Abstract
Coprophagy is of great significance to the growth, development, and reproductive performance of rabbits. This study is aimed at exploring the effect of coprophagy on the reproductive performance of New Zealand white rabbits by coprophagy prevention (CP). The results showed that CP treatment significantly decreased the growth and development performance of female rabbits and the live birth rate of embryos. The results of blood biochemical indexes showed that CP treatment significantly increased the contents of serum ALB, ALP, and MDA, while serum SOD activity was significantly decreased. Transcriptome analysis showed that GO terms were mainly enriched in transport function and reproductive function after CP treatment. In addition, KEGG results showed that inflammation related signal pathways were activated and the expression level of genes related to tight junction proteins was downregulated by CP treatment. Concurrently, western blot further confirmed the results of KEGG. In short, fecal feeding is an important survival strategy for some small rodents, coprophagy prevention will affect the inflammatory level of the body, change the oxidative stress level of the body, and then activate NOX4-ROS-NF-κB pathway, increase the expression level of adhesion protein ICAM-1 and VCAM-1, lead to the damage of uterine epithelial barrier, and then affect the reproductive performance of rabbits.
