Reappraisal to the study of 4E-BP1 as an mTOR substrate – A normative critique

•The treatment of divergent viewpoints is an inherent challenge for assessments.•Scientific and political/ethical divergent views can be hard to distinguish.•Nine general approaches for conflict treatment are used in assessment processes.•All approaches possess various context-specific strengths and weaknesses.•A promising approach is to jointly explore implications of policy alternatives. mTOR-4E-BP1 axis is regarded as the best oncogenic circuitry impinging on translational control whereby mTORC1 dictates post-translational regulation of 4E-BP1. This review provides new insights into the molecular network of signalling pathways highlighting the recent explosion of studies in respect to the deviant behaviour of 4E-BP1 towards mTORC1. Despite the striking conservation of mTOR nexus, the eccentric phosphorylation dynamics of 4E-BP1 negate the apparent linear architecture of mTORC1 attesting the importance of other kinases that may evoke cross-talks with the conventional frame, most of which are enlisted in the manuscript. We also throw light on the tenuous role of rapamycin in 4E-BP1 regulation, which further necessitates the evaluation of 4E-BP1 to envisage the underlying molecular mechanisms in the discovery of novel drugs of 4E-BP1 for new treatment strategies. Finally, the review brings forward comprehensive studies delineating the redundancy of 4E-BP isoforms in regulating translational control.
