BDNF and cancer: Previous research has established that both physical and neuronal activity significantly upregulate BDNF gene expression in the brain,37,38 leading to the activation of signaling pathways that enhance learning and memory through exercise-dependent mechanisms.31 Future research should explore the specific contributions of yoga components to BDNF regulation, including its distinct fractions and underlying mechanistic pathways, to better understand its role in cognitive recovery among cancer survivors.39
