Project description:Ischemia reperfusion injury (IRI) in organ transplantation remains a significant problem with limited alternative therapeutic options. Organs that undergo significant damage during IRI, particularly those enduring long warm ischemia times, undergo significant delayed graft function (DGF) after reperfusion and tend to have greater complications long term with the onset of chronic rejection. The gas molecule carbon monoxide (CO) has emerged as an agent that can suppress IRI in rodent models of solid organ transplantation. Since the use of CO is a potential therapeutic modality in humans, we tested if CO can prevent DGF in a pig model of kidney transplantation Keywords: stress response, treatment response 18 Samples from pig kidneys, two naïve controls, two timepoints, two conditions, 4 replicates

Project description:Primary graft dysfunction (PGD), which is caused primarily by ischemia–reperfusion injury (IRI), is a major obstacle in lung transplantation. Here, we developed an orthotopic, single-lung transplant pig model to simulate prolonged cold IRI. After 24 hours of cold ischemia and 8 hours of warm reperfusion, the transplanted lung exhibited severe allograft injury. Subsequent single-cell RNA sequencing (scRNA-seq) revealed significant changes in alveolar macrophages after IRI, with prominently enriched ferroptosis pathways. Transmission electron microscopy (TEM) confirmed characteristic ferroptosis changes in lung macrophages, and decreased GPX4 expression in macrophages indicated increased susceptibility to ferroptosis. Overall, our pig orthotopic left lung transplant model effectively simulates IRI after transplantation, which offers a valuable platform for more detailed investigations of early reperfusion injury to pulmonary grafts. Moreover, we preliminarily demonstrated the importance of macrophage ferroptosis in IRI, suggesting that inhibiting macrophage ferroptosis may be a promising therapeutic strategy for lung IRI.

Project description:Successful production of offspring in mammals is determined by the growth and apoptosis pathway, which is responsible for maintaining the balance between the estrous cycle. It is also believed that the development of the porcine ovary is regulated similarly; however, the molecular mechanism underlying differences in follicle development in the minipig and pig has yet to be elucidated. The present study aimed to identify developmental-associated genes differentially expressed in the minipig vs. pig.

Project description:To identify the direct m6A demethylation targets of ALKBH5 at the onset of renal IRI, we performed methylated RNA immunoprecipitation sequencing (MeRIP-seq) and RNA sequencing (RNA-seq) using RNA isolated from IRI mouse kidney of WT and KO mice 24h after I/R (WT n=3 vs. KO n=3)

Project description:Mannose-specific interactions of Lactobacillus plantarum 299v with jejunal epithelium were investigated using an in situ pig small intestinal segment perfusion (SISP) model. L. plantarum 299v wildtype strain was compared to two isogenic mutant strains either lacking the gene encoding for the mannose-specific adhesin (msa) or sortase (srtA; responsible for anchoring of cell surface proteins like Msa to the cell wall). Salmonella typhimurium served as a positive control for gene expression analysis. Scrapings from jejunal segments were collected after perfusion with bacterial suspensions or PBS (control) for 4 or 8 hours, and host gene expression was assessed using a home-made cDNA porcine microarray. Keywords: host-microbe interaction, Lactobacillus plantarum, mannose-specific adhesion A Small Intestinal Segment Perfusion (SISP) test was performed using 4 pigs. 10 segments were prepared in the jejunum of each pig and perfused with Lactobacillus plantarum 299v wildtype, Lactobacillus plantarum 299v msa mutant strain, Lactobacillus plantarum 299v srtA mutant strain, Salmonella typhimurium or PBS (control) for 4 or 8 hours. Pooled samples from each treatment at each timepoint were used for microarray analysis. 8 comparisons were done: L. plantarum wildtype vs control (4 hours), L. plantarum wildtype vs control (8 hours), L. plantarum msa mutant vs control (4 hours), L. plantarum msa mutant vs control (8 hours), L. plantarum srt mutant vs control (4 hours), L. plantarum srt mutant vs control (8 hours), S. typhimurium vs control (8 hours), samples taken at the beginning of the experiment vs control (8 hours). Dye-swaps were performed for each comparison.

Project description:We analyzed differences in IRI kidneys between WT and Keap1 KD mice (= Nrf2-activated mice). To identify Nrf2-target genes or metabolic genes in kidneys, we examined the mRNA expression profile both in normal (uninjured) and IRI kidneys (at day1 after unilateral IRI) from mice We performed microarray analyses using 1) Injured kidneys at day 1 after unilateral IRI, and 2) intact kidneys from mice which did not undergo UIRI. Samples were harvested from Keap1 KD mice and WT mice, n = 2 each,
