AI Article Synopsis
- Bacterial lipopolysaccharide (LPS) exposure leads to intestinal inflammation and reduced growth in weaned piglets, impacting the swine industry economically.
- Baicalin, a compound from Scutellaria baicalensis, may alleviate this inflammation through its anti-inflammatory properties.
- The study suggests that baicalin targets the PARP1 protein to regulate inflammation-related pathways, potentially serving as a therapeutic option for LPS-induced intestinal injury.
Article Abstract
Bacterial lipopolysaccharide (LPS) exposure is a key inducer of intestinal inflammatory injury in weaned piglets, resulting in decreased growth performance of pigs and causing severe economic losses to the swine industry; however, the mechanism of intestinal inflammatory injury is still unclear. Baicalin is one of the main active ingredients extracted from the natural plant Scutellaria baicalensis that has biological functions, including anti-inflammatory activity. The aim of this study is to investigate the effect and mechanism of baicalin intervention on intestinal inflammatory injury caused by bacterial LPS exposure. In the present study, network pharmacology, molecular docking and DARTS results identified that baicalin has the potential to target PARP1, thereby potentially regulating a series of inflammation-related pathways, including the MAPK, NF-κB and Toll-like receptor signalling pathways, which play the role of antagonizing LPS-induced intestinal inflammatory injury. Further application of the LPS-induced IPEC-J2 cell model validated the finding that baicalin could alleviate LPS-induced intestinal inflammatory injury by inhibiting the PARP1-mediated NF-κB and NLRP3 signalling pathway. These findings demonstrate that baicalin can regulate the expression of PARP1 and that PARP1 has the potential to serve as an effective therapeutic target in the LPS-induced intestinal inflammatory injury.

The lack of knowledge about the mechanism of hyperoxia-induced intestinal injury has attracted considerable attention, due to the potential for this condition to cause neonatal complications. This study aimed to explore the relationship between hyperoxia-induced oxidative damage and ferroptosis in intestinal tissue and investigate the mechanism by which hyperoxia regulates inflammation through ferroptosis. The study systematically evaluated the effects of hyperoxia on oxidative stress, mitochondrial damage, ferroptosis, and inflammation of intestinal epithelial cells both in vitro and in vivo.

Nutrient availability strongly affects intestinal homeostasis. Here, we report that low-protein (LP) diets decrease amino acids levels, impair the DNA damage response (DDR), cause DNA damage and exacerbate inflammation in intestinal tissues of male mice with inflammatory bowel disease (IBD). Intriguingly, loss of nuclear fragile X mental retardation-interacting protein 1 (NUFIP1) contributes to the amino acid deficiency-induced impairment of the DDR in vivo and in vitro and induces necroptosis-related spontaneous enteritis.

Lymphoma is the most common neoplasia in the intestine of cats. According to ACVIM consensus statement, low-grade intestinal T-cell lymphoma (LGITCL) represents a monomorphic infiltration of the lamina propria or epithelium or both of cats with small, mature, neoplastic (clonal) T lymphocytes. Despite the importance as contributing factors of inheritance and environment in the pathogenesis of LGITCL, the chronic inflammatory status plays a fundamental role.

With the increasing incidence of non-hereditary Parkinson's disease (PD), research into the involvement of specific environmental factors, in addition to aging, has become more prominent. The effects of microplastic exposure on public health have gained increased attention as it is known to cause a range of neurotoxic changes, some of which are similar to the pathological features of PD. We carried out low-dose microplastic exposure experiments on mice and Caenorhabditis elegans models and implemented a survey regarding the utilization of plastic products in the population.

Background: Epidemiological associations between kidney stone disease (KSD) and gastrointestinal disorders have been reported, and intestinal homeostasis plays a critical role in stone formation. However, the underlying intrinsic link is not adequately understood. This study aims to investigate the genetic associations between these two types of diseases.
