Consistent with its redox role, alterations in GSH homeostasis influence cellular sensitivity to oxidative stress, mitochondrial dysfunction, and multiple forms of regulated cell death
Paget observed that primary tumor cells of a given type of cancer preferentially metastasized to one or more particular distant organ sites, detectable metastases only developed at those sites (soils) where the tumor cells (seeds) were adapted for survival and proliferation [21]
The VEGFR2-Akt-eNOS signaling pathway might be activated without the need for other known ligands or shear stress, controlling vasomotor tone and the activation of the Src-Caveolin-1-eNOS pathway [60,61]
This escalation should only occur if the lower dose is well-tolerated and additional benefit is needed to achieve treatment goals
External factors such as stress do not only affect the sperm count, morphology, and motility
