Project description:Bronchopulmonary dysplasia (BPD) remains the most frequent chronic lung disease among infants, which involves multifactorial pathogenesis. Necroptosis represents a caspase-independent mode of programmed cell death, and its deregulation associates with lung diseases, but the mechanisms of necroptosis during BPD are indistinct. This work was conducted for unveiling the post-transcriptional regulatory mechanisms of necroptosis in BPD.
Project description:Understanding the regulatory roles of small RNAs (sRNAs) in Mycobacterium marinum is crucial for elucidating its pathogenesis. Here, we present transcriptome profiles of M. marinum strains with deletions and completions of sRNA B11. Through RNA sequencing analysis, we identified significant alterations in gene expression patterns between the B11-deleted and completed strains.
Project description:Schizophrenia is a complex and severe neuropsychiatric disorder, with a wide range of debilitating symptoms. Several aspects of its multifactorial complexity are still unknown, and some are accepted to be an early developmental deficiency with a more specifically neurodevelopmental origin. ??Molecular and functional abnormalities in astrocytes play a role in the etiology and pathogenesis of schizophrenia. In this study, human induced pluripotent stem cells (hiPSC)-derived astrocytes from schizophrenia patients were investigated regarding their proteome, inflammatory responses, and their secretome effect on vascularization. Proteomic analysis revealed alterations in proteins related to immune function and vascularization. Taken together, our results suggest that schizophrenia astrocytes are immunologically dysfunctional which might affect vascularization through secreted factors.

Project description:To elucidate the epithelial cell diversity within the nasal inferior turbinates, a comprehensive investigation was conducted comparing control subjects to individuals with house dust mite-induced allergic rhinitis. This study aimed to delineate the differential expression profiles and phenotypic variations of epithelial cells in response to allergic rhinitis. This research elucidated distinct subpopulations and rare cell types of epithelial cells within the nasal turbinates, discerning alterations induced by allergic rhinitis. Furthermore, by interrogating transcriptomic signatures, the investigation provided novel insights into the cellular dynamics and immune responses underlying allergic rhinitis pathogenesis
Project description:Genome wide association studies (GWAS) have identified single nucleotide polymorphisms (SNPs) associated with diseases of the colon including inflammatory bowel diseases (IBD) and colorectal cancer (CRC). However, the functional role of many of these SNPs is largely unknown and tissue-specific resources are lacking. Expression quantitative trait loci (eQTL) mapping identifies target genes of disease-associated SNPs. Here, we comprehensively map eQTLs in the human colon, assess their relevance for GWAS of colonic diseases and provide functional characterization.
Project description:Transplant rejection is a major factor limiting allograft survival. CircRNAs are reported to be strongly associated with various diseases pathogenesis. However, the potential role of circRNAs in cardiac transplant rejection are rarely reported. Here, differentially expressed mRNAs and circRNAs were determined by microarrays in allogeneic cardiac allografts. Functional analysis was then performed and a full-scale functional blueprint of the circRNA-associated-ceRNA networks was constructed. Among the circRNA networks, circ23123 expression was negatively linked with cytolytic molecules of CD8+ T cells by targeting miR155-SOCS1 axis. We illustrated a new comprehensive view of circRNAs and their potential functional impact in cardiac transplantation. It may provide a prospective for therapeutic strategy on organ transplant rejection in the future.
