Structure comparison techniques are benefiting from the ever-expanding repositories of the Protein Data Bank. The development of computational tools for protein and amino acid 3D structural comparisons plays an important role in understanding protein functions. The Triangular Spatial Relationship (TSR)-based was developed for such purpose. Methods: A parallelization strategy and actual implementation on high-performance clusters using the distributed and shared memory programming model, along with the utilization of multi-core CPU and many-core GPU accelerators, were developed. 3D structures of proteins and amino acids are represented by an integer vector in the TSR-based method. This parallelization strategy is designed for the TSR-based method for large-scale 3D structural comparisons of proteins and amino acids in this study. It can also be adapted to other applications where a vector type of data structure is used. Results: Due to the nature of the vector representation of protein and amino acid structures using the TSR-based method, the comparison algorithm is well-suited for parallelization on large scale supercomputers. Performance studies on the representative datasets were conducted to demonstrate the efficiency of the parallelization strategy. It allows comparisons of large 3D protein or amino acid structure datasets to finish within a reasonable amount of time. Conclusion: The case studies, by taking advantage of this parallelization code, demonstrate that applying either mirror image or feature selection in the TSR-based algorithms improves the classifications of protein and amino acid 3D structures. The TSR keys have the advantage of performing structure-based BLAST searches. The parallelization code could be used as a reference for similar future studies.","PeriodicalId":10801,"journal":{"name":"Current Bioinformatics","volume":null,"pages":null},"PeriodicalIF":4.0,"publicationDate":"2024-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141881446","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to propose a computational model, SIDMF, for predicting miRNA-disease associations. Background: Computational methods have proven efficient in predicting miRNA-disease associations, leveraging functional similarity and network-based inference. Machine learning techniques, including support vector machines, semi-supervised algorithms, and deep learning models, have gained prominence in this domain. Objective: Develop a computational model that integrates disease semantic similarity and miRNA functional similarity within a deep matrix factorization framework to predict potential associations between miRNAs and diseases accurately. Methods: SIDMF, introduced in this study, integrates disease semantic similarity and miRNA functional similarity within a deep matrix factorization framework. Through the reconstruction of the miRNA-disease association matrix, SIDMF predicts potential associations between miRNAs and diseases. Results: The performance of SIDMF was evaluated using global Leave-One-Out Cross-Validation (LOOCV) and local LOOCV, achieving high Area Under the Curve (AUC) values of 0.9536 and 0.9404, respectively. Comparative analysis against other methods demonstrated the superior performance of SIDMF. Case studies on breast cancer, esophageal cancer, and prostate cancer further validated SIDMF's predictive accuracy, with a substantial percentage of the top 50 predicted miRNAs confirmed in relevant databases.

This study addresses the limitations of existing research by proposing a comprehensive machine-learning framework to identify key mortality risk factors and develop a robust predictive model. Objective: This study proposes an analytical framework that leverages various machine learning techniques to predict the survival of hospitalized COVID-19 patients accurately. The framework comprehensively evaluates multiple clinical indicators and their associations with mortality risk. Method: Patient data, including gender, age, health condition, and smoking habits, was divided into discharged (n=507) and deceased (n=300) categories. Each patient was characterized by 92 clinical features. The framework incorporated seven feature ranking algorithms (LASSO, LightGBM, MCFS, mRMR, RF, CATBoost, and XGBoost), the IFS method, and four classification algorithms (DT, KNN, RF, and SVM). Results: Age, diabetes, dyspnea, chronic kidney failure, and high blood pressure were identified as the most important risk factors. The best model achieved an F1-score of 0.857 using KNN with 34 selected features.

Highthroughput biological experimental methods such as CLIP-seq can effectively analyze the interaction between the two, but biological experiments are inefficient and expensive, and they can only capture binding sites of a specific RBP on circRNA in a selected cell environment at a time. These biological experiments still rely on downstream data analysis to understand the mechanisms behind many biological structures and physiological processes. However, the rapid growth of experimental data dimensions and production speed pose challenges to traditional analysis methods. In recent years, deep learning has made great progress in the genome and transcriptome, and some deep learning prediction algorithms for RBP binding sites on circRNA have also emerged. In this paper, we briefly introduce some biological background knowledge related to circRNA-RBP interaction; present relevant deep learning techniques in this field, including the problem formulation, data source, sequence encoding, deep learning model and overall process of RBP binding sites prediction on circRNA; deeply analyze the current deep learning methods. Finally, some problems existing in the current research and the direction of future research are discussed.

Method: Various traditional Chinese medicine (TCM) therapies have been recommended for patients with monkeypox virus (MPXV). However, as far as we know, there is no comprehensive database dedicated to preserving and coordinating TCM remedies for combating MPXV. To address this gap, we introduce TCM@MPXV, a carefully curated repository of research materials focusing on formulations with anti-MPXV properties. Importantly, TCM@MPXV extends its scope beyond herbal remedies, encompassing mineral-based medicines as well. Result: The current iteration of TCM@MPXV boasts an impressive array of features, including (1) Documenting over 42 types of TCM herbs, with more than 27 unique herbs; (2) Recording over 285 bioactivity compounds within these herbs; (3) Launching a user-friendly web server for the docking, analysis, and visualization of 2D or 3D molecular structures; and (4) Providing 3D structures of druggable proteins of MPXV. Conclusion: To summarize, TCM@MPXV presents a user-friendly and effective platform for recording, querying, and viewing anti-MPXV TCM resources and will contribute to the development and explanation of novel anti-MPXV mechanisms of action to aid in the ongoing battle against monkeypox.
