The molecular basis of IGF-II/IGF2R recognition: a combined molecular dynamics simulation, free-energy calculation and computational alanine scanning study.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Insulin-like growth factor-II (IGF-II) is a key regulator of cell growth, survival, migration and differentiation, and is thus pivotal in many cancers. An individual with a high IGF-II level is at high risk of developing cancer, whereas IGF2R is implicated as being important in tumor suppression. Thus, uncovering the essence of the IGF-II/IGF2R interaction is very important to understanding the origin of the tumor-suppressing effect of IGF2R. In this study, in order to investigate the interaction of the IGF-II/IGF2R complex and to characterize the binding hot spots of this interaction, a 10 ns molecular dynamics simulation combined with MM-PBSA/MM-GBSA computations and computational alanine scanning was performed on the IGF-II/IGF2R complex. From the results of the free-energy decomposition and the computational alanine scanning calculation, we identified the key residues in the IGF-II/IGF-2R interaction. The results from the calculation were consistent with reported experimental mutagenesis studies. The information on the interaction of IGF-II and IGF2R obtained is vital for understanding how the structure of IGF2R influences the function of IGF-II in growth and development. This study will also lead to new opportunities to develop molecular probes that can assist in diagnostic screening, and even novel approaches to controlling tumor development.
