Osimertinib / ER Stress Cancer Research Results

Osi, Osimertinib: Click to Expand ⟱
Features:
Osimertinib works by selectively inhibiting the activity of EGFR, which is a protein that plays a critical role in the growth and survival of cancer cells. By blocking the activity of EGFR, osimertinib prevents the growth and proliferation of cancer cells, leading to tumor shrinkage and improved survival.
Osimertinib has been shown to be effective in patients with NSCLC who have specific EGFR mutations. In the AURA3 trial, osimertinib significantly improved progression-free survival (PFS) compared with platinum-based chemotherapy. In the FLAURA trial, osimertinib significantly improved PFS and overall survival (OS) compared with erlotinib or gefitinib.
ER Stress, endoplasmic reticulum (ER) stress signaling pathway: Click to Expand ⟱
Source:
Type:
Protein expression of ATF, GRP78, and GADD153 which is a hall marker of ER stress.
The endoplasmic reticulum (ER) stress signaling pathway plays a crucial role in maintaining cellular homeostasis and responding to various stressors, including those encountered in cancer. When cells experience stress, such as the accumulation of misfolded proteins, they activate a series of signaling pathways collectively known as the unfolded protein response (UPR). The UPR aims to restore normal function by enhancing the protein-folding capacity of the ER, degrading misfolded proteins, and, if the stress is unresolved, triggering apoptosis.
The activation of ER stress pathways can contribute to resistance against chemotherapy and targeted therapies. Cancer cells may utilize the UPR to survive treatment-induced stress, making it challenging to achieve effective therapeutic outcomes.

-ER stress-associated proteins include: phosphorylation of PERK, eIF2α, ATF4, CHOP and cleaved-caspase 12
