AI Technical Summary

Technical Problem

Current technologies cannot effectively assess the activity of the metabolic enzyme 3βHSD1, resulting in low accuracy in predicting prostate cancer malignancy in the Chinese population, which fails to meet clinical needs.

Method used

By collecting gene expression data from the prostate tissue of subjects, decision tree models and random forest models were established to calculate transcriptomic fingerprint scores and assess the activity of the metabolic enzyme 3βHSD1, thus assisting in the assessment of the risk of prostate cancer malignancy.

Benefits of technology

It provides a method for assessing the activity of the metabolic enzyme 3βHSD1 applicable to the Chinese population, which improves the accuracy of predicting the malignant trend of prostate cancer and supports early diagnosis and treatment.

Abstract

本发明的一种评估代谢酶3βHSD1活性的方法及系统,包括以下步骤:S1,收集受试者基因表达的样本数据;S2,选择若干受试者基因表达,计算其基因的子节点的基尼值,S3,选定每一个基因的子节点中数值最小的Gini(D)作为该转录组指纹中的基因表达量的最优分割点;S4,选用步骤S3中的若干个最优分割点建立一个决策树模型;S5,重复步骤S2‑S5,建立多个决策树模型,构成随机森林模型,S6,得到代谢酶3βHSD1活性的分数,作为转录组指纹的分数。本发明的一种评估代谢酶3βHSD1活性的方法及系统,建立了转录组指纹来表征前列腺组织3βHSD1代谢活性,可以提供给医生作为高效的前列腺癌风险早期诊断的生物标志物。
