Does eeyarestatin cause cervical cancer cell sensitization to bortezomib treatment by augmenting ER stress and CHOP expression?
Eeyarestatin is a small molecule recently shown to cause endoplasmic reticulum stress by inhibiting the endoplasmic reticulum-associated degradation pathway, which directs misfolded cytotoxic proteins to proteasomal degradation. Concomitant inhibition of both pathways markedly enhances the efficacy of bortezomib against cervical cancer cells and thus may be applied to reduce the bortezomib dosage required for efficient cervical cancer treatment.
Double-stranded DNA (along or in combination with cyclophosphamide) induces massive apoptosis of Krebs-2 ascite cells and MCF-7 cell line (DNA only). In treated mice it reduces the integrity of gut wall cells and contributes to the development of systemic inflammatory reaction.
