Project description:In the present study, we were interested in gene expression changes in the pectoralis muscle of juvenile king penguins during the transition from terrestrial to marine life. Strictly terrestrial during their first year after hatching, king penguin chicks must then depart to sea to reach nutritional emancipation and pectoralis muscle is largely involved in penguin adaptation to the marine environment. To compare these transcriptomic profiles, we realized heterologous hybridization on Affymetrix GeneChip Chicken Genome Arrays, as the chicken is the closest model species for which microarrays are available. The development of a new algorithm, MaxRS, allow us to determine differentially expressed genes implicated in energetic metabolism or involved in cellular defense against reactive oxygen species and associated injuries. We compared muscle sample biopsy from 4 penguin juveniles captured just before they undergone their first immersion to cold water (named NI for Never Immersed) and 3 penguin juveniles that had completly accomplished their acclimation to marine life (named SA for Sea Acclimated).

Project description:We introduce the Promoter-ENhancer-GUided Interaction Networks (PENGUIN) approach to identify protein-protein interactions (PPI) within enhancer-promoter (E-P) interactions. By integrating high-coverage H3K27ac-HiChIP data and tissue-specific PPI networks, PENGUIN identifies functional clusters in E-P networks. Here, we applied PENGUIN to E-P networks of prostate cancer (PrCa) cell line LNCaP. We validated PENGUIN's structural classification by observing clear differential enrichment of the architectural protein CTCF. One of our 8 main clusters, comprising 273 promoters, showed significant enrichment for PrCa-associated single nucleotide polymorphisms (SNPs) and oncogenes. Our approach provides a mechanistic explanation for 208 PrCa SNPs located within DNA-binding protein (DBP) binding sites or intermediate protein-encoding genes involved in E-P contacts. CRISPR analysis in the LNCaP cell line confirmed the relevance of these SNPs in PrCa. PENGUIN confirms the importance of key regulators in PrCa and identifies new intervention candidates, offering new directions for identifying molecular targets in disease treatment. Data was generated in the Matthew L. Freedman lab.

Project description:Exposure to high-dose radiation causes life-threatening serious intestinal damage. Histological analysis is the most accurate method for judging the extent of intestinal damage after death. However, it is difficult to predict the extent of intestinal damage to body samples. Here we focused on extracellular microRNAs (miRNAs) released from cells and investigated miRNA species that increased or decreased in serum and feces using a radiation-induced intestinal injury mouse model. A peak of small RNA of 25–200 nucleotides was detected in mouse serum and feces 72 h after radiation exposure, and miRNA presence in serum and feces was inferred. MiRNAs expressed in the small intestine and were increased by more than 2.0-fold in serum or feces following a 10 Gy radiation exposure were detected by microarray analysis and were 4 in serum and 19 in feces. In this study, miR-375-3p, detected in serum and feces, was identified as the strongest candidate for a high-dose radiation biomarker in serum and/or feces using a radiation-induced intestinal injury model.

Project description:Sixty crossbred piglets (Duroc*Landrace*Yorkshire) weaned at the age of 21 days were maintained for one week and had free access to feed and water. During this week, all the piglets were scored for the severity of diarrhea. Diarrhea index was scored as follows: 1= hard feces; 2= no scours, feces of normal consistency; 3= mild scours, soft, partially formed feces; 4= moderate scours, loose, semi-liquid feces; 5= watery feces; as previously did Those piglets with a score of 4 or 5 for three continuous days were designated as diarrhea piglets, while those piglets with a score of 1 or 2 for three continuous days were designated as normal piglets..

Project description:To further identify the fecal miRNAs generated in HE, we conducted an miRNA microarray analysis on feces collected from patients with HE and CHB. The microarray analysis of miRNA expression profiles revealed that the abundance of 10 miRNAs was significantly increased in feces from patients with HE, as compared with that from patients with CHB, whereas the abundance of 8 miRNAs was decreased.

Project description:To explore the effects of gut microbiota of young (8 weeks) or old mice (18～20 months) on stroke, feces of young (Y1-Y9) and old mice (O6-O16) were collected and analyzed by 16s rRNA sequencing. Then stroke model was established on young mouse receive feces from old mouse (DOT1-15) and young mouse receive feces from young mouse (DYT1-15). 16s rRNA sequencing were also performed for those young mice received feces from young and old mice.
