In this study, a gene signature was defined through the analysis of cisplatin-perturbed gene expression and pathway enrichment, and a cisplatin sensitivity prediction model was developed using the TabNet algorithm. The TabNet model outperformed other machine learning models with an accuracy of over 80%. Furthermore, BCL2L1 was identified as an important gene contributing to cisplatin resistance, and its pharmacological inhibition was found to enhance cisplatin efficacy. This study developed a tool to predict cisplatin sensitivity and identified BCL2L1 as a significant gene in this context.
Cisplatin, a platinum-based chemotherapeutic agent, is widely used as a front-line treatment for several malignancies. However, treatment outcomes vary widely due to intrinsic and acquired resistance. In this study, cisplatin-perturbed gene expression and pathway enrichment were used to define a gene signature, which was further utilized to develop a cisplatin sensitivity prediction model using the TabNet algorithm. The TabNet model performed better (> 80 % accuracy) than all other machine learning models when compared to a wide range of machine learning algorithms. Moreover, by using feature importance and comparing predicted ovarian cancer patient samples, BCL2L1 was identified as an important gene con-tributing to cisplatin resistance. Furthermore, the pharmacological inhibition of BCL2L1 was found to sy-nergistically increase cisplatin efficacy. Collectively, this study developed a tool to predict cisplatin sensitivity using cisplatin-perturbed gene expression and pathway enrichment knowledge and identified BCL2L1 as an important gene in this setting.(c) 2023 The Author(s).
