研究问题
Quantifying protein phosphorylations and interactions across signaling networks is essential for quantitative biology and systems medicine. Current standard methods like immunoblotting offer limited throughput, precision, and scalability. We present an inverse-precision multiplex workflow based on a 3D hydrogel platform, enabling quantification of protein modifications and interactions within one assay. We chose the example of the mTORC1 (mTOR complex 1) kinase - 4E-BP1/2 signaling axis, clinically targeted by cancer therapies, which tunes protein biosynthesis to nutrient supply and stress.

本文核心结论来自动物模型或体外细胞学，属临床前证据，不能外推至人体。「延长健康寿命」「改善功能」等表述在小鼠中的意义，与人类临床结局之间仍有距离。
