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:Despite increasing efforts in miRNAs identification across various species and diverse tissue types, little is known about porcine gonad-specific miRNAs. Although the well-known importance of pig in agriculture, as well as a model for human biology, the miRNA catalog of pig has been largely undefined. Identification and preliminary characterization of gonad-specific miRNAs would be a prerequisite for a thorough understanding of their roles in regulating folliculogenesis and spermatogenesis. In the present study, we get insight into miRNA transcriptome in adult porcine ovary and testis using deep sequencing technology, and to elucidate their characteristic organ- and gender-specific profiles, genomic context and emphasize the features of X-linked miRNAs. Two small RNA libraries from adult porcine ovary and testis tissues were sequenced.

Project description:Minipigs are animal models widely used in biomedical studies due to their physiological and anatomical similarities to humans. However, a comprehensive resource for the Korean minipig (Sus scrofa) transcriptome remains unavailable. In this study, we constructed a de novo transcriptome of the Korean minipig using RNA-seq data obtained from ten tissues across ten samples. The final assembly comprised 57,085 coding transcripts with an average length of 3,075 nucleotides and an N50 of 4,258 nucleotides. In total, 65.4% of the transcripts were annotated, and biological functions were assigned. Transcript expression profiling and principal component analysis showed that samples clustered by tissue type, reflecting transcriptomic features shared across tissues. Comparative analysis demonstrated that the novel transcriptome assembly had contiguity and completeness comparable to those available for pig and minipig breeds. Overall, this study provides a comprehensive transcriptomic resource for the Korean minipig, facilitating further functional analyses.

Project description:Lung ischemia-reperfusion (I/R) injury remains one of the common complications after various cardiopulmonary surgeries. I-R injury represents one potentially maladaptive response of the innate immune system which is featured by an exacerbated sterile inflammatory response triggered by tissue damage. Thus, understanding the key components and processes involved in sterile inflammation during lung I-R injury is critical to alter care and extend survival for patients with acute lung injury. We constructed a minipig surgical model of transient unilateral left pulmonary artery occlusion without bronchial involvement to create ventilated lung I-R injury. Lung tissues from minipig with sham operation (one sample), left side lung tissues (the operated side)(one sample) and right side lung tissues (the non-operated side)(one sample) from minipig with lung ischemia-reperfusion were submitted for gene expression array analysis.

Project description:Porcine reproductive and respiratory syndrome caused by porcine reproductive and respiratory syndrome virus (PRRSV) is an infectious disease characterized by severe reproductive deficiency in pregnant sows, respiratory symptoms in piglets, and high mortality. In this study, we employed Affymetrix microarray chip technology to compare the gene expression profiles of lung tissue samples from Dapulian (DPL) pigs (a Chinese indigenous pig breed) and Duroc×Landrace×Yorkshire (DLY) pigs after infection with PRRSV. During infection with PRRSV, the DLY pigs exhibited the range of clinical features that typify the disease, while the DPL pigs exhibited only mild signs of the disease. The percentage of CD8+ T cells in the DPL pigs was significantly higher than that in the DLY pigs at 21 days post-infection (dpi) (p< 0.05). Interleukin (IL) 1 beta (IL-1β) and IL-2 levels showed significant differences between the DPL and DLY pigs at 0 and 7 dpi (p< 0.01). For IL-10, the DLY pigs had significantly higher values than the DPL pigs at 0 and 7 dpi (p< 0.01). Significant differences were apparent between the DPL and DLY pigs in terms of their tumor necrosis factor-alpha (TNF-α) and interferon (IFN)-gamma (IFN-γ) levels at 0 and 7 dpi (p< 0.01). Microarray data revealed 16 differentially expressed genes in the lung tissue samples from the DLY and DPL pigs (q≤5%), of which LOC100516029 and LOC100523005 were up-regulated in the PRRSV-infected DPL pigs, while the other 14 genes were down-regulated in the PRRSV-infected DPL pigs compared with the PRRSV-infected DLY pigs. The expression levels of 10 of the 16 genes, namely CCDC84, C6ORF52, THYMOSIN, PRVE, HSPCB, CYP2J2, AMPD3, TOR1AIP2, PTGES3, and ACOX3, were validated by real-time quantitative RT-PCR. This study provides a platform for further investigation of the molecular mechanisms underlying the differential immune responses to PRRSV infection in different breeds or lines of pig. We investigated the response of lung tissues from Dapulian (DPL) pigs (a Chinese indigenous pig breed) and Duroc×Landrace×Yorkshire (DLY) pigs infected with porcine reproductive and respiratory syndrome virus (strain JXA1) by using the Affymetrix Porcine Genome Array.
