The study found that H 2 S pretreatment of ECs can improve mitochondrial function and cell viability after hypoxia treatment by activating extracellular regulated protein kinases (ERK) 1/2, as well as enhance ECs migration and angiogenesis, thereby protecting ECs from ischemia/reperfusion injury and gradually reducing cardiac damage (97)

Higher doses are often required to achieve higher CNS exposure, which in turn increases the risk of systemic toxicity

Note that this probability increases from low to high values over a relatively short period in the life history of the tumor and that drug-resistant cells are likely to be established prior to clinical detection
