Indeed, KEs and KERs are shared by multiple AOPs. agnostic, tool chemical compounds were selected to empirically support the response and temporal concordance of the key event relationships (KERs). Three qualitative and one putative AOP were developed by the Panel?using the results obtained. The Panel?supports the use of the AOP framework to scientifically and transparently explore the biological plausibility of the association between pesticide exposure and human health outcomes, identify data gaps, define a tailored testing strategy and suggests an AOP’s informed Integrated Approach for Testing and Assessment (IATA). exposure to relevant environmental risk factors for the development of the disease, they display distinct pathological pathways. Furthermore, while for CHL, the Panel?was not able to identify tool chemicals that were able to induce the disease in the experimental models, for IFL enough evidence supported the applicability of the anticancer drug etoposide as a tool. Symptoms and signs of overt paediatric leukaemia were chosen as AO, although the disease as such is not an apical endpoint in the regulatory toxicity studies. Taking into account the above limitations, it has been considered scientifically acceptable to develop a qualitative AOP relevant for IFL and to design only a putative AOP for CHL. The development of these two different AOPs, also in comparison to AOPs relevant for PD, allowed evaluating the flexibility of such an approach. In line with the selected AO and the prototype chemical etoposide for IFL, a MIE in utero topoisomerase II poisoning was defined. It was linked to the selected AO through a single KE summarised as in utero MLL chromosomal rearrangement. The overall weight of evidence suggests that the link between the MIE and the AO is strong and that the proposed events can be used to explore the IFL\triggering hazard of chemicals. As stated, the AOP developed for CHL is based on weaker biological plausibility. However, a hypothetical biological plausibility could exist but cannot be convincingly formulated with the currently available circumstantial information. Although epidemiological observations suggest that the association of the disease to exposure to pesticides, complexities in defining a definite MIE and involvement of modulating factors as well as limitations in the standard design of regulatory studies for the exploration of tumour\related endpoints following exposure prevent building a convincing qualitative AOP. In addition, the Panel?recognises that an animal model recapitulating the disease is not available and this is also weakening the assessment. Based on the results obtained, the Panel?supports the use of the AOP framework to scientifically and transparently explore the biological plausibility of the epidemiological association between pesticide exposures and human health outcomes. Moreover, pesticides triggering the MIEs of the proposed AOPs should be considered as potential risk factors with respect to the development of analysed diseases, considering the power of the AOP framework, at its best, to provide quantitative knowledge of biological pathways leading to an AO on a weight of evidence basis. The Panel?also identified a number of uncertainties regarding the three major areas explored during the development of this Scientific Opinion, i.e. epidemiological studies, experimental studies and AOP development. Although the AOPs developed in the present Scientific Opinion only explain a small fraction of the supposed interactions of pesticides, PD and paediatric leukaemia risk, the Panel?considered the?outcome of this approach promising. Thus, a multitude of AOPs might be developed to investigate the potential link of various pesticides to the different symptoms of the considered diseases. Beside this very relevant point, the AOP framework also represents a suitable scaffold to help identifying data gaps by analysing the weight of evidence for each KER within the defined.Transplantation of human fetal dopamine cells for Parkinson’s disease. the available experimental knowledge to assess biological plausibility by describing the link between a molecular initiating event (MIE) and the AO through a series of biologically plausible and essential key events (KEs). As the AOP is chemically agnostic, tool chemical compounds were selected to empirically support the response and temporal concordance of the 3,4-Dehydro Cilostazol key event associations (KERs).

The Panel?supports the use of the AOP platform to scientifically and transparently explore the biological plausibility of the association between pesticide exposure and human being health results, identify data gaps, define a tailored screening strategy and suggests an AOP’s informed Integrated Approach for Screening and Assessment (IATA). exposure to relevant environmental risk factors for the development of the disease, they display unique pathological pathways. Furthermore, while for CHL, the Panel?was not able to identify tool chemicals that were able to induce the disease in the experimental models, for IFL plenty of evidence supported the applicability of the anticancer drug etoposide as a tool.

It was linked to the selected AO through a single KE summarised as with utero MLL chromosomal rearrangement. The overall weight of evidence suggests that the link between the MIE and the AO is definitely strong and that the proposed events can be used to explore the IFL\triggering risk of chemicals.

Beside this very relevant point, the AOP framework also represents a suitable scaffold to help identifying data gaps by analysing the weight of evidence for each KER within the defined AOPs. In addition, by suggesting and providing quantitative and measurable markers for critical biological events leading to the development of an AO, the AOP framework may help in the revision of regulatory studies underlining any limitation in the appropriate identification of effects and mode of actions relevant to complex human diseases, PD and paediatric leukaemia in the specific investigated case. Summarising, the application of an AOP represents a transparent and weighted approach to.

The overall weight of proof suggests that the hyperlink between your MIE as well as the AO can be strong which the suggested events may be used to explore the IFL\triggering risk of chemical substances. As mentioned, the AOP created for CHL is dependant on weaker natural plausibility.
