The journey from high-risk HLA alleles and viral mimicry to targeted destruction of pancreatic beta cells highlights a disease process that is now decipherable at the mechanistic level

Knockdown of ARNTL2 significantly decreases the expression levels of Nrf2, SLC7A11, and CDGSH iron-sulfur domain protein 1 of lung adenocarcinoma cells, and increases the sensitivity to ferroptosis

These proteins are crucial for cell-to-cell and cell-to-matrix interactions, playing important roles in tissue integrity and wound healing
