In fact, the consequences of such differences over the disease mechanisms or the drug action mechanisms are completely unknown. Here we applied mechanistic mathematical models of signaling activity to reveal the ultimate functional consequences that gender-specific gene expression activities have over cell functionality and fate. Moreover, we also used the mechanistic modeling framework to simulate the drug interventions and unravel how drug action mechanisms are affected by gender-specific differential gene expression. Interestingly, some cancers have many biological processes significantly affected by these gender-specific differences (e.g., bladder or head and neck carcinomas), while others (e.g., glioblastoma or rectum cancer) are almost insensitive to them. We found that many of these gender-specific differences affect cancer-specific pathways or in physiological signaling pathways, also involved in cancer origin and development. Finally, mechanistic models have the potential to be used for finding alternative therapeutic interventions on the pathways targeted by the drug, which lead to similar results compensating the downstream consequences of gender-specific differences in gene expression.</p>10aFemale10aGene Expression Regulation, Neoplastic10aHumans10aMale10aNeoplasms10aSignal Transduction1 aCubuk, Cankut1 aCan, Fatma, E1 aPeña-Chilet, Maria1 aDopazo, Joaquin  uhttps://www.clinbioinfosspa.es/content/mechanistic-models-signaling-pathways-reveal-drug-action-mechanisms-behind-gender-specific
