Array technology to genotype single-nucleotide variants (SNVs) is widely used in genome-wide association studies (GWAS), clinical diagnostics, and linkage studies. Arrays have undergone a tremendous growth in both number and content over recent years making a comprehensive comparison all the more important. We have compared 28 genotyping arrays on their overall content, genome-wide coverage, imputation quality, presence of known GWAS loci, mtDNA variants and clinically relevant genes (i.e., American College of Medical Genetics (ACMG) actionable genes, pharmacogenetic genes, human leukocyte antigen (HLA) genes and SNV density). Our comparison shows that genome-wide coverage is highly correlated with the number of SNVs on the array but does not correlate with imputation quality, which is the main determinant of GWAS usability. Average imputation quality for all tested arrays was similar for European and African populations, indicating that this is not a good criterion for choosing a genotyping array. Rather, the additional content on the array, such as pharmacogenetics or HLA variants, should be the deciding factor. As the research question of a study will in large part determine which class of genes are of interest, there is not just one perfect array for all different research questions. This study can thus help as a guideline to determine which array best suits a study's requirements.Cord blood (CB) represents a source of hematopoietic stem and progenitor cells (CB-HSPCs) for bone marrow (BM) reconstitution, but clinical CB application is limited in adult patients due to the insufficient number of CB-HSCPCs and the lack of effective ex vivo approaches to increase CB-HSPC functionality. Since human-induced pluripotent stem cells (hiPSCs) have been indicated as donor cells for bioactive extracellular vesicles (EVs) modulating properties of other cells, we are the first to employ hiPSC-derived EVs (hiPSC-EVs) to enhance the hematopoietic potential of CB-derived CD45dimLin-CD34+ cell fraction enriched in CB-HSPCs. We demonstrated that hiPSC-EVs improved functional properties of CB-HSPCs critical for their hematopoietic capacity including metabolic, hematopoietic and clonogenic potential as well as survival, chemotactic response to stromal cell-derived factor 1 and adhesion to the model components of hematopoietic niche in vitro. Moreover, hiPSC-EVs enhanced homing and engraftment of CB-HSPCs in vivo. This phenomenon might be related to activation of signaling pathways in CB-HSPCs following hiPSC-EV treatment, as shown on both gene expression and the protein kinases activity levels. In conclusion, hiPSC-EVs might be used as ex vivo modulators of CB-HSPCs capacity to enhance their functional properties and augment future practical applications of CB-derived cells in BM reconstitution.Polypharmacy poses a significant risk for adverse reactions. While there are clinical decision support tools to assist clinicians in medication management, pharmacogenetic testing to identify potential drug-gene or drug-drug-gene interactions is not widely implemented in the clinical setting. A PRISMA-compliant scoping review was performed to determine if pharmacogenetic testing for absorption, distribution, metabolism, and excretion (ADME)-related genetic variants is associated with improved clinical outcomes in patients with polypharmacy. Six studies were reviewed. Five reported improved clinical outcomes, reduced side effects, reduction in the number of drugs used, or reduced healthcare utilization. The reviewed studies varied in methodological quality, risk of bias, and outcome measures. Age, diet, disease state, and treatment adherence also influence drug response, and may confound the relationship between genetic polymorphisms and treatment outcomes. Further studies using a randomized control design are needed. We conclude that pharmacogenetic testing represents an opportunity to improve health outcomes in patients exposed to polypharmacy, particularly in patients with psychiatric disorders and the elderly.SWItch/Sucrose Non-Fermentable (SWI/SNF) is a multiprotein complex essential for the regulation of eukaryotic gene expression. SWI/SNF complex genes are genetically altered in over 20% of human malignancies, but the aberrant regulation of the SWI/SNF subunit genes and subsequent dysfunction caused by abnormal expression of subunit gene in cancer, remain poorly understood. read more Among the SWI/SNF subunit genes, SMARCA4, SMARCC1, and SMARCA2 were identified to be overexpressed in human hepatocellular carcinoma (HCC). Modulation of SMARCA4, SMARCC1, and SMARCA2 inhibited in vitro tumorigenesis of HCC cells. However, SMARCA4-targeting elicited remarkable inhibition in an in vivo Ras-transgenic mouse HCC model (Ras-Tg), and high expression levels of SMARCA4 significantly associated with poor prognosis in HCC patients. Furthermore, most HCC patients (72-86%) showed SMARCA4 overexpression compared to healthy controls. To identify SMARCA4-specific active enhancers, mapping, and analysis of chromatin state in liver cancer cells were performed. Integrative analysis of SMARCA4-regulated genes and active chromatin enhancers suggested 37 genes that are strongly activated by SMARCA4 in HCC. Through chromatin immunoprecipitation-qPCR and luciferase assays, we demonstrated that SMARCA4 activates Interleukin-1 receptor-associated kinase 1 (IRAK1) expression through IRAK1 active enhancer in HCC. We then showed that transcriptional activation of IRAK1 induces oncoprotein Gankyrin and aldo-keto reductase family 1 member B10 (AKR1B10) in HCC. The regulatory mechanism of the SMARCA4-IRAK1-Gankyrin, AKR1B10 axis was further demonstrated in HCC cells and in vivo Ras-Tg mice. Our results suggest that aberrant overexpression of SMARCA4 causes SWI/SNF to promote IRAK1 enhancer to activate oncoprotein Gankyrin and AKR1B10, thereby contributing to hepatocarcinogenesis.Long non-coding RNAs (lncRNA) play crucial roles in hepatocellular carcinoma (HCC) progression. However, the specific functions of lncRNAs in alternative splicing (AS) and the metastatic cascade in liver cancer remain largely unclear. In this study, we identified a novel lncRNA, LINC01348, which was significantly downregulated in HCC and correlated with survival functions in HCC patients. Ectopic expression of LINC01348 induced marked inhibition of cell growth, and metastasis in vitro and in vivo. Conversely, these phenotypes were reversed upon knockdown of LINC01348. Mechanistically, LINC01348 complexed with splicing factor 3b subunit 3 (SF3B3) acted as a modulator of EZH2 pre-mRNA AS, and induced alterations in JNK/c-Jun activity and expression of Snail. Notably, C-terminal truncated HBx (Ct-HBx) negatively regulated LINC01348 through c-Jun signaling. Our data collectively highlight those novel regulatory associations involving LINC01348/SF3B3/EZH2/JNK/c-Jun/Snail are an important determinant of metastasis in HCC cells and support the potential utility of targeting LINC01348 as a therapeutic strategy for HCC.
