In NCVR, the molecular vertical relationship that can be characterized in simple terms was proposed for network construction, thereby facilitating to better advance clinical decision making. To effectively measure the discriminative ability of molecular vertical relationship between different physiological and pathological stages, the joint probability mass function was constructed using sample frequency which can reduce the influence of sample variability caused by individual differences and the probability of over fitting caused by the high complexity of molecular expression data. NCVR was successfully employed to analyze the similarities and differences of living organisms treated by different treatment patterns (i.e., NIR and apoferritin-conjugated cypate (Cy@AFT) + NIR) on BC. The results of similarity analysis indicated that the reprogramming of cellular lipid and energy metabolism may be responsible for the BC cell death induced by treatments. Experimental results of difference analysis suggested that the disruptions in cholesterol metabolism, ferroptosis and severe lipid metabolism imbalances etc. contribute to the enhanced effectiveness of BC treatment with Cy@AFT + NIR. Then, analysis results of genes related to the selected key metabolites further provided deep insights into pathological alterations associated with BC development and illustrated why the performance of Cy@AFT + NIR therapy is better than that of NIR therapy.</div></div>","PeriodicalId":7830,"journal":{"name":"Analytical biochemistry","volume":"702 ","pages":"Article 115852"},"PeriodicalIF":2.6,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143725015","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
