Pantothenic acid
Overexpression of the bifunctional l-glutathione synthetase GshF from S
EGF treatment increased H 2 O 2 production, which activated the AKT/p70S6K1 pathway to transcriptionally enhance VEGF expression
Medications- Certain medications, such as proton pump inhibitors and metformin, can interfere with B12 absorption, leading to deficiency over time
As the primary factors for the reduced anticancer effect 1) the reduced delivery and uptake of the anticancer agent, 2) the need for the conversion of molecular oxygen (O 2 ) into reactive oxygen species (ROS), 3) the preferred therapeutic effect against highly proliferating cells, which is reduced under hypoxic conditions, or 4) adaptation of the cancer cells by promoting cell survival and upregulating certain resistance pathways, has been suggested 1,2,3,4,5
