This enzyme supports bacterial survival during both active growth and dormancy, enabling Mtb to persist under stressful conditions. During dormancy, Mtb enters a non-replicating, drug-tolerant state that reduces the effectiveness of many antibiotics. Inhibition of ATP synthase therefore disrupts ATP-dependent survival mechanisms in Mtb. Although this target has been clinically validated by bedaquiline, the emergence of resistance and the limited chemical diversity of reported inhibitors indicate a clear need for new ATP synthase-targeting compounds. In this study, we employed an integrative pipeline combining structure-based pharmacophore modeling, artificial neural network-driven quantitative structure-activity relationship (ANN-QSAR) modeling, and absorption distribution metabolism excretion and toxicity (ADMET)-based pharmacokinetic filtering strategies to screen an antituberculosis-targeted library of approximately 4200 molecules from the Life Chemicals database. Initial screening identified 8 hit molecules characterized by key molecular features previously highlighted as positive contributors in both Shapley Additive Explanations (SHAP) and Pearson correlation analyses, including SubFP1 (primary carbon), SubFP88 (carboxylic acid derivative), SubFP143 (carbonic acid derivative), SubFP9 (alkyl fluoride), SubFP137 (vinylogous ester), SubFP184 (heteroaromatic), SubFP26 (tertiary aliphatic amine), and SubFP171 (aryl chloride). Molecular docking and molecular dynamics simulation studies (200 ns) further highlighted molecules F0526-1306 and F0526-1309 as the most promising candidates.

Even though RNF20 has been investigated in some cancer types, its global biological functions and other related mechanisms in diverse cancers are yet to be fully understood. To investigate the systematical evaluation of the pan-cancer expression pattern of RNF20 and its potential to serve as a diagnostic and prognostic biomarker, we first pulled together the information of several publicly available databases and bioinformatics tools. We compared association between RNF20 expression and important clinical and molecular variables-including clinical survival outcomes, immunomodulatory molecular, tumor stemness index, prognostic use, immunomodulatory molecular, genomic and immunological variables, immunotherapy response, response to chemotherapeutic agents, and functional enrichment profiles. The levels of RNF20 were also substantially greater in tumor tissues relative to identical non-tumor tissues; furthermore, the high levels of RNF20 in some cancer tissues are associated with the good prognostic outcome. The subsequent studies demonstrated that RNF20 is highly correlated with the immune checkpoint molecules, immunomodulatory genes, prognostic biomarkers, tumor stemness scores, as well as immune cell infiltration in various tumors. The SN-38 and talazoparib were identified as possible RNF20-targeting agents through drug susceptibility analysis. It was revealed that missense mutations are most frequent type of variations, which is revealed by functional enrichment analysis, mutation profiling, RNA modification mapping and analysis of genomic heterogeneity of the RNF20 related genes within the framework of glioblastoma, glioma, low-grade glioma in addition to thyroid cancer.

In this study, we combined classical molecular dynamics (MD) simulations with artificial intelligence (AI)-based unsupervised learning approaches to investigate the conformational dynamics and binding selectivity of ERK1/2-inhibitor complexes. Six systems, comprising ERK1 and ERK2 bound to inhibitors 33A, 38Z, and Z48, were simulated for 250 ns to capture their structural and energetic behaviors. Root mean square deviation (RMSD) and fluctuation (RMSF) analyses confirmed that all complexes reached equilibrium, with ERK2 systems exhibiting greater structural stability than ERK1. Radius of gyration (Rg) and hydrogen-bond profiles support consistent compactness and persistent interactions throughout the trajectories. The AI-based dimensionality reduction (principal component analysis [PCA], t-distributed stochastic neighbor embedding [t-SNE]) and K-means clustering revealed distinct conformational basins, indicating ligand-specific modulation of ERK flexibility. Free energy landscape mapping and state transition analyses demonstrated that Z48-bound systems showed more compact and stable conformational basins, reflecting enhanced conformational stabilization, whereas 33A complexes exhibited higher dynamic variability. In contrast, molecular mechanics/generalized Born surface area (MM/GBSA) binding free energy calculations showed that 38Z exhibits the strongest binding affinity toward both ERK isoforms, driven primarily by favorable van der Waals interactions. Overall, this combined MD-AI framework provides atomistic insights into ERK1/2 conformational plasticity and inhibitor selectivity, highlighting 38Z as the most energetically favorable binder and Z48 as the most effective conformational stabilizer.

Addressing these complex health threats requires innovative approaches to data analysis, pathogen surveillance, and intervention design. The emergence of advanced computational tools especially artificial intelligence (AI) is expected to reduce turnaround times for AMR prediction from days to hours by leveraging whole-genome sequencing (WGS)-based models. This article explores the synergistic integration of AI and bioinformatics, focusing on their application in combating AMR in Africa. It details how AI techniques, particularly machine learning (ML) and deep learning (DL) algorithms, can enhance genomic research by automating the analysis of large-scale sequence datasets, predicting resistance patterns, and modeling infections transmission dynamics. In regions with limited laboratory capacity, AI models can detect resistance genes rapidly and assist clinicians in selecting appropriate antibiotics, offering a faster and more scalable alternative to traditional diagnostics. Tools such as convolutional neural networks (CNNs) and support vector machines (SVMs) are examples of models capable of classifying pathogen strains based on genetic data. Furthermore, the article highlights the emerging role of large language models (LLMs) in supporting bioinformatics workflows. These tools aid researchers by generating analysis scripts, interpreting complex outputs, troubleshooting code errors, summarizing literature, and preparing manuscripts or grant proposals particularly benefiting early-career scientists who may lack access to advanced training or mentorship. Despite notable progress, significant challenges remain, including limited infrastructure, barriers to data sharing, and the urgent need for ethical guidelines and policies to govern AI integration. Ultimately, this article underscores the transformative potential of AI in advancing bioinformatics across Africa and advocates for sustained investment in infrastructure, capacity-building, and responsible policy frameworks to harness AI for improved health research and disease control outcomes.
