Triple negative breast cancer (TNBC) is the most aggressive subtype of breast cancer in women. It has the poorest prognosis along with limited therapeutic options. Smart nano-based carriers are emerging as promising approaches in treating TNBC due to their favourable characteristics such as specifically delivering different cargos to cancer cells. However, nanoparticles' tumour cell uptake, and subsequent drug release, are essential factors considered during the drug development process. Contemporary qualitative analyses based on imaging are cumbersome and prone to human biases. Deep learning-based algorithms have been well-established in various healthcare settings with promising scope in drug discovery and development. In this study, the performance of five different convolutional neural network models was evaluated. In this research, we investigated two sequential models from scratch and three pre-trained models, VGG16, ResNet50, and Inception V3. These models were trained using confocal images of nanoparticle-treated cells loaded with a fluorescent anticancer agent. Comparative and cross-validation analyses were further conducted across all models to obtain more meaningful results. Our models showed high accuracy in predicting either high or low drug uptake and release into TNBC cells, indicating great translational potential into practice to aid in determining cellular uptake at the early stages of drug development in any area of research.
三阴性乳腺癌(TNBC)是女性中最具侵袭性的乳腺癌亚型。它的预后最差,治疗选择有限。由于智能纳米载体具有特定向癌细胞输送不同有效载荷的有利特性,因此它们作为治疗 TNBC 的有前途的方法而出现。然而,纳米颗粒的肿瘤细胞摄取以及随后的药物释放是药物开发过程中考虑的重要因素。基于成像的当代定性分析繁琐且容易受到人为偏见的影响。基于深度学习的算法已在各种医疗保健环境中得到很好的建立,并在药物发现和开发方面具有广阔的应用前景。在这项研究中,评估了五种不同卷积神经网络模型的性能。在这项研究中,我们从头开始研究了两个连续模型和三个预先训练的模型,即 VGG16、ResNet50 和 Inception V3。这些模型使用载有荧光抗癌剂的纳米颗粒处理细胞的共聚焦图像进行训练。进一步对所有模型进行了对比和交叉验证分析,以获得更有意义的结果。我们的模型在预测 TNBC 细胞中药物摄取和释放的高低方面表现出很高的准确性,这表明它们具有很大的转化潜力,可以在药物开发的早期阶段帮助确定任何研究领域的细胞摄取。
