2) L’hypothèse d’une intervention dans le cadre de l’article
Buscando por novos alvos terapêuticos para o CaP, especialmente entre os genes envolvidos em vias de estresse oxidativo, encontramos a enzima SRXN1, cuja expressão mostrou-se aumentada nos estágios avançados do tumor prostático. Sua up regulação está associada ao pior prognóstico do CaP e a menor sobrevida dos pacientes. Essa enzima antioxidante tem papel importante na manutenção do equilíbrio redox intracelular, contribuindo com o processo de sobrevivência e progressão tumoral, uma vez que sua inibição reduziu a viabilidade de células cancerosas prostáticas. Assim, no contexto da medicina de precisão, nosso trabalho aponta a inibição da SRXN1 como uma potencial estratégia para o tratamento adjuvante do “CaP resistente à castração” em pacientes que tenham superexpressão dessa enzima. Nossos resultados também demonstraram que a expressão proteica e gênica da SRXN1 é diferentemente modulada por testosterona, flutamida, fibronectina e H2O2 em células prostáticas e que essa modulação depende dos
diferentes metabolismos celulares. Assim, considerando que o tumor prostático é altamente heterogêneo, ainda é necessário um melhor entendimento sobre como a expressão de SRXN1 é regulada nas diferentes fases de progressão do CaP para o desenvolvimento de novas estratégias de tratamento a partir do uso de inibidores específicos para SRXN1.
