Portal:AOP/Mission

The purpose of this portal is to create a collection of AOPs on the molecular level for the AOPs that are, or will be created for the EU-ToxRisk program, in which Open PHACTS Foundation (OPF) is responsible for AOP creation. The subjects of the first AOPs are linked to the use cases of the EU-ToxRisk program, and there will be a team of experts involved in the creation of each AOP.


The proposed list of the first set of AOPs to be created, some are more defined than others:

  • Chemical-induced bile duct obstruction leads to liver failure
  • Chemical-induced bile duct obstruction leads to nephrotoxicity
  • Inhibition of N-linked glycosylation leads to liver injury
  • Mitochondrial complex inhibition leading to liver injury
  • Inhibition of mitochondrial complex I of nigra-striatal neurons leads to parkinsonian motor deficits
  • Peripheral neuropathy caused by microtubule interacting drugs
  • Oxidative reactivity leads to chemical-induced fanconi syndrome
  • Binding to complex I of the electron transport chain leading to chemical-induced Fanconi syndrome
  • Intracellular accumulation of chemicals via the megalin/cubulin system leading to tubulonephritis
  • Oxidant-induced pulmonary emphysema
  • α-diketone-induced bronchiolitis obliterans
  • HDAC inhibition leads to neural tube defects
  • Cyp17 inhibition leads to undescended testes
  • Oxidative stress-induced liver injury
  • IKK complex inhibition leads to liver failure
  • HDAC inhibition leads to impaired craniofacial development
