Web12. júl 2024 · In fact, several challenges are restraining the clinical utility of PLK1 inhibitors. First, most of the PLK1 inhibitors achieved therapeutic effects only when doses exceeded toxic limits. Second, the responses to PLK1 inhibitors reported from different studies were discrepant. Finally, the emergence of drug resistance is a major challenge [ 1, 3 ]. WebDespite the positive influence of PERK inhibition in these studies, there were secondary side effects of pancreatic toxicity, because of the requirement of PERK activity to modulate ER stress which results from the high levels of insulin production in the pancreas [201,202]. A recent approach was to reduce PERK activity but only partially, by ...
A novel specific PERK activator reduces toxicity and …
WebThe cells respond to ER stress by activating the unfolded protein response (UPR), a signaling network emerging from the ER-anchored receptors IRE1α, PERK and ATF6. The UPR aims at restoring ER protein-folding homeostasis, but turns into a toxic signal when the stress is too severe or prolonged. WebPancreatic Toxicity Pancreatic toxicity is generally characterized by dysregulation of lipid metabolism and edema in early reversible stages, followed by massive necrosis resulting in inflammation, with or without fibrosis (scarring of the tissue) at the advanced stages.
