摘要:

癌症是人类死亡的主要原因,但发现药物和定制癌症疗法既昂贵又耗时。我们寻求促进新的药物和癌症治疗策略的发现,使用变分自编码器(VAE)和多层感知器(MLP)来预测抗癌药物反应。我们的模型以癌细胞系的基因表达数据和抗癌药物分子数据作为输入,并分别用我们的{ \sc {GeneVae}}模型(这是一个普通的VAE模型)和整流连接树变分自编码器({ \sc JTVae})模型对这些数据进行编码。多层感知器处理这些编码特征以产生最终预测。我们的测试表明,我们的系统在预测乳腺癌细胞系的药物反应方面达到了高的平均决定系数($R^{2} = 0.83$),并且对于泛癌细胞系达到了平均$R^{2} = 0.845$。此外,我们表明,我们的模型可以产生以前未用于特定癌细胞系的有效药物化合物。

英文摘要:

Cancer is a primary cause of human death, but discovering drugs and tailoring cancer therapies are expensive and time-consuming. We seek to facilitate the discovery of new drugs and treatment strategies for cancer using variational autoencoders (VAEs) and multi-layer perceptrons (MLPs) to predict anti-cancer drug responses. Our model takes as input gene expression data of cancer cell lines and anti-cancer drug molecular data and encodes these data with our {\sc {GeneVae}} model, which is an ordinary VAE model, and a rectified junction tree variational autoencoder ({\sc JTVae}) model, respectively. A multi-layer perceptron processes these encoded features to produce a final prediction. Our tests show our system attains a high average coefficient of determination ($R^{2} = 0.83$) in predicting drug responses for breast cancer cell lines and an average $R^{2} = 0.845$ for pan-cancer cell lines. Additionally, we show that our model can generates effective drug compounds not previously used for specific cancer cell lines.
