EGCG was found to disrupt TGF- signaling through downregulating TGF- receptor and Smad4 expression, resulting in stimulating the expression of glutamate-cysteine ligase to enhance de novo glutathione synthesis in HSCs, thereby inhibiting HSC proliferation associated with oxidative stress ( de novo glutathione synthesis was necessary for EGCG to block TGF- signaling and diminished the expression of 1(I) collagen in activated HSCs ( In HCC, it was previously believed that the recurrence and metastasis after radiotherapy were only attributed to the invasive effects of remaining hepatoma cells, whereas it is now realized that this is closely relevant to the enhanced metastasis potential of remaining hepatoma cells caused by radiation treatment ( In vitro experiments confirmed that radiotherapy enhanced TLR4 signaling in HSCs and upregulated ICAM-1, 67LR, IL-6, and CX3C chemokine ligand 1, among which EGCG bound to 67LR to inhibit TLR4 signaling and radiation-induced HSC invasion ( in vivo and in vitro experiments detected EGCG triggered a series of senescence phenotypes in activated HSCs ( 3.4 Mesenchymal stem/stromal cells MSCs, which are found in almost all human tissues and are given the ability to transdifferentiate into various connective tissue lineages, such as adipocytes and chondrocytes, can migrate to the tumorigenic sites to participate in the formation of tumor stroma ( Relevant data illuminated the regulatory effect of EGCG on the signaling cascade of MSCs, that is, EGCG attenuated TLR signaling and subsequent MT1-MMP expression, causing the suppression of MT1-MMP-mediated sequential phosphorylation of Src, JAK, and STAT3, thereby inhibiting the expression of CSF-2 and CSF-3 responsible for endothelial angiogenesis in TME (172)

The increase in Hb oxidation during storage of RBCs may also be due to a decrease in their antioxidant capacity, resulting in the oxidation and deterioration of membrane lipids and proteins, which can ultimately lead to irreversible damage to the membrane

adverse or undesired effects Examples -- positive, beneficial drug interaction effects: Propranolol + hydralazine (reflex tachycardia (undesirable) caused by hypotensive hydralazine-mediated response is prevented by propranolol-mediated -adrenergic receptor blockade Opioid-induced respiratory depression may be counteracted by administration of the opioid receptor antagonist naloxone Adverse effects -- toxic reactions One drug may interact with another to impede absorption One drug may compete with another for the same plasma protein-binding sites One drug may affect metabolism of another by either enzyme induction or enzyme inhibition One drug may change the renal excretion rate of the other
