Minute oxidative stress is sufficient to induce apoptotic death of NIT‐1 insulinoma cells

BT Olejnicka, H Dalen, UT Brunk - Apmis, 1999 - Wiley Online Library
When cultured NIT‐1 cells were subjected to a low level of oxidative stress (30 μM hydrogen

Starvation-induced autophagocytosis paradoxically decreases the susceptibility to oxidative stress of the extremely oxidative stress-sensitive NIT insulinoma cells

BT Olejnicka, H Dalen, MM Baranowski, UT Brunk - Redox report, 1997 - Taylor & Francis
Glucose and amino acid starvation of cells in culture generally enhances their sensitivity to
oxidative stress. This is explained by compensatory autophagocytosis, which results in …
