A growing body of evidence indicates that circular RNAs (circRNAs) play a pivotal role in various biological processes and have close association with the initiation progression diseases. Moreover, circRNAs are considered as promising biomarkers for disease diagnosis owing to their characteristics conservation, stability universality. Inferring disease-circRNA relationships will contribute understanding pathology. However, it is costly laborious discover novel interactions by wet-lab experiments, few computational methods been devoted predicting potential Here, we advance method (NCPCDA) identify circRNA-disease associations based on network consistency projection. For starters, make use multi-view similarity data, including circRNA functional similarity, semantic profile construct integrated similarity. Then, project space interaction network, respectively. Finally, can obtain predicted score matrix combining above two projection scores. Simulation results show NCPCDA efficiently infer high accuracy, obtaining AUCs 0.9541 0.9201 leave-one-out cross validation five-fold validation, Furthermore, case studies also suggest discovering new interactions.

Exploring the relationship between circular RNA (circRNA) and disease is beneficial for revealing mechanisms of pathogenesis. However, a blind search all possible associations circRNAs diseases through biological experiments time-consuming. Although some prediction methods have been proposed, they still limitations. In this study, novel computational framework, called GATCL2CD, proposed to forecast unknown circRNA-disease (CDAs). First, we calculate Gaussian interactive profile kernel (GIP) similarity semantic diseases, circRNA sequence function similarity, GIPs circRNAs. Then, combine them construct heterogeneous graph. Thereafter, GATCL2CD proposes feature convolution learning that uses multi-head dynamic attention mechanism obtain different aggregated representations features correspond nodes in it extracts rich higher-order from stacked each node by using single-layer convolutional neural network with filter kernels sizes. Finally, pairwise element-wise product operation implemented capture interactions representations, multilayer perceptron introduced as an efficient classifier inferring potential CDAs. Major experimental results under 5-fold cross-validation (5-fold CV) on three datasets show superior five other state-of-the-art methods. Furthermore, case studies demonstrate suitability useful tool identifying disease-related

In the emerging field of RNA drugs, circular (circRNA) has attracted much attention as a novel multifunctional therapeutic target. Delving deeper into intricate interactions between circRNA and disease is critical for driving drug discovery efforts centered around circRNAs. Current computational methods face two significant limitations: lack aggregate information in heterogeneous graph networks higher-order fusion information. To this end, we present approach, metaCDA, which utilizes meta-knowledge adaptive learning to improve accuracy association predictions addresses limitations both. We calculate multiple similarity measures circRNA, construct based on these, apply meta-networks extract from graph, so that constructed maps have contrast enhancement Then, nodal aggregation system, integrates multihead mechanism mechanism, achieve accurate capture conducted extensive experiments, results show metaCDA outperforms existing state-of-the-art models can effectively predict disease-associated opening up new prospects circRNA-driven discovery.

A drug-drug interaction (DDI) is defined as an association between two drugs where the pharmacological effects of a drug are influenced by another drug. Positive DDIs can usually improve therapeutic patients, but negative cause major adverse reactions and even result in withdrawal from market patient death. Therefore, identifying has become key component development disease treatment. In this study, we propose novel method to predict based on integrated similarity semi-supervised learning (DDI-IS-SL).
