The increased accessibility to genomic data in recent years has laid the foundation for studies to predict various phenotypes of organisms based on the genome. Genomic prediction collectively refers to these studies, and it estimates an individual's phenotypes mainly using single nucleotide polymorphism markers. Typically, the accuracy of these genomic prediction studies is highly dependent on the markers used; however, in practice, choosing optimal markers with high accuracy for the phenotype to be used is a challenging task. Therefore, we present a new tool called GMStool for selecting optimal marker sets and predicting quantitative phenotypes. The GMStool is based on a genome-wide association study (GWAS) and heuristically searches for optimal markers using statistical and machine-learning methods. The GMStool performs the genomic prediction using statistical and machine/deep-learning models and presents the best prediction model with the optimal marker-set. For the evaluation, the GMStool was tested on real datasets with four phenotypes. The prediction results showed higher performance than using the entire markers or the GWAS-top markers, which have been used frequently in prediction studies. GSK429286A cell line Although the GMStool has several limitations, it is expected to contribute to various studies for predicting quantitative phenotypes. The GMStool written in R is available at www.github.com/JaeYoonKim72/GMStool .The dynamic structure-function (DSF) model was previously shown to have better prediction accuracy than ordinary least square linear regression (OLSLR) for short series of visits. The current study assessed the external validity of the DSF model by testing its performance in an independent dataset (Ocular Hypertension Treatment Study-Confocal Scanning Laser Ophthalmoscopy [OHTS-CSLO] ancillary study; N = 178 eyes), and also on different test parameters in a sample selected from the Diagnostic Innovations in Glaucoma Study or the African Descent and Glaucoma Evaluation Study (DIGS/ADAGES). Each model was used to predict structure-function paired data at visits 4-7. The resulting prediction errors for both models were compared using the Wilcoxon signed-rank test. In the independent dataset, the DSF model predicted rim area and mean sensitivity paired measurements more accurately than OLSLR by 1.8-5.5% (p ≤ 0.004) from visits 4-6. Using the DIGS/ADAGES dataset, the DSF model predicted retinal nerve fiber layer thickness and mean deviation paired measurements more accurately than OLSLR by 1.2-2.5% (p ≤ 0. 007). These results demonstrate the external validity of the DSF model and provide a strong basis to develop it into a useful clinical tool.β-Catenin is an important component of the Wnt signalling pathway. As dysregulation or mutation of this pathway causes many diseases, including cancer, the β-Catenin level is carefully regulated by the destruction complex in the Wnt signalling pathway. However, the mechanisms underlying the regulation of β-Catenin ubiquitination and degradation remain unclear. Here, we find that WNK (With No Lysine [K]) kinase is a potential regulator of the Wnt signalling pathway. We show that WNK protects the interaction between β-Catenin and the Glucose-Induced degradation Deficient (GID) complex, which includes an E3 ubiquitin ligase targeting β-Catenin, and that WNK regulates the β-Catenin level. Furthermore, we show that WNK inhibitors induced β-Catenin degradation and that one of these inhibitors suppressed xenograft tumour development in mice. These results suggest that WNK is a previously unrecognized regulator of β-Catenin and a therapeutic target of cancer.Human umbilical cord blood (hUCB)-derived hematopoietic stem cells (HSCs) are an important source for HSCs in allogeneic HSC transplantation, but a limited number and a low efficacy of engraftment greatly restrict their clinical use. Here, we report the ability of photobiomodulation therapy (PBMT) to significantly enhance the engraftment efficacy of hUCB HSCs and progenitor cells (HSPCs). hUCB CD34+ cells were illuminated at a fluence of 2 J/cm2 with a near-infrared light (830 nm) transmitted by an array of light-emitting diodes (LED) prior to infusion of NOD/SCID-IL2Rγ-/- mice. The pre-treatment resulted in a threefold higher of the mean percentage of human CD45+ cells in the periphery of the mice compared to sham-treated CD34+ cells. The enhanced engraftment may result from a PBMT-mediated increase of intracellular reactive oxygen species (ROS) levels and Src protein phosphorylation in CD34+ cells. The two events were causally related as suggested by the finding that elevation of ROS by hydrogen peroxide increased Src phosphorylation, while ROS reduction by N-acetyl cysteine partially reversed the phosphorylation. The investigation demonstrates that PBMT can promote engraftment of hUCB HPSCs, at least in part, via ROS-mediated Src signaling pathway. PBMT can be potentially a safe, convenient, and cost-effective modality to improve hematological reconstitution in patients.Inhaler education for chronic obstructive pulmonary disease (COPD) patients improves inhaler technique and adherence. However, the effects of such education on the quality of life and inhaler satisfaction remain unclear. Here, we evaluated inhaler handling and adherence, and changes in quality of life and inhaler satisfaction, after repeated education for COPD patients. We prospectively enrolled COPD patients who had used inhalers for over 1 month and evaluated the effects of repeated education. Three visits were made over 6 months; an advanced practice nurse evaluated inhaler technique and adherence, and instructed the patients in inhaler technique during face-to-face sessions. Inhaler technique and adherence were assessed at every visits, and the modified Medical Research Council (mMRC) test, COPD Assessment Test (CAT), EuroQol-5D (EQ-5D), Patient Health Questionnaire (PHQ-9), and Feeling of Satisfaction with Inhaler questionnaire (FSI-10) were administered before (visit 1) and after two educational sessions (visit 3). A total of 261 COPD patients (308 inhalers) were included. Education significantly reduced the proportion of critical errors after two educational sessions (visit 3), from 43.2 to 8.8% (p  less then  0.001). The proportion of highly compliant patients increased after two visits, from 81.6% to 87.7% (p = 0.005). The FSI-10 score improved significantly after education, from 44.36 ± 4.69 to 47.64 ± 4.08 (p  less then  0.001); the scores on the other instruments (mMRC, CAT, EQ-5D, and PHQ-9) did not improve. Repeated face-to-face inhaler education by an advanced practice nurse significantly improved inhaler satisfaction, technique, and adherence. However, inhaler education did not significantly improve quality of life.
