Potential therapeutic role of sex steroids in treating sarcopenia: a network pharmacology and molecular dynamics study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundSarcopenia, characterized by progressive muscle loss and functional decline in aging, poses significant health challenges. Sex steroids, such as estradiol and testosterone, have potential therapeutic roles in mitigating muscle degeneration. This study explores the molecular mechanisms and targets of sex steroids in the treatment of sarcopenia using network pharmacology, enrichment analysis, machine learning, molecular docking, and molecular dynamics simulations.
methodsWe identified potential anti-sarcopenia targets by analyzing the interaction network between sex steroids and their targets, intersecting these with differentially expressed genes (DEGs) from the GSE1428. Enrichment analysis was conducted to determine the functional relevance of these targets. Gene set variation analysis (GSVA) was employed to explore pathway-level differences between age groups. Machine learning algorithms (RF, SVM, XGBoost) identified crucial biomarker genes. A nomogram for predicting sarcopenia was constructed and validated. Molecular docking and molecular dynamics (MD) simulations evaluated the binding interactions and stability of steroid-target complexes.
resultsIntersection analysis revealed 69 potential anti-sarcopenia targets. Enrichment analysis highlighted pathways related to muscle function, such as calcium signaling and synaptic transmission. GSVA indicated significant upregulation of DNA damage response and immune response pathways in the older group. Machine learning algorithms pinpointed CFTR, FYN, and PRKCA as top biomarkers. The nomogram demonstrated high predictive accuracy with an AUC of 0.925. Molecular docking showed significant binding affinities of sex steroids with target proteins, further supported by stable RMSD values in MD simulations.
conclusionSex steroids, specifically estradiol and testosterone, demonstrate promising interactions with key targets implicated in sarcopenia in silico. These computational findings offer preliminary mechanistic insights into the potential therapeutic role of sex steroids in modulating muscle-related pathways. Further experimental and clinical validation is warranted to assess their translational applicability for sarcopenia treatment. CLINICAL TRIAL NUMBER: Not applicable.
