SOX30 Facilitates Triple‐Negative Breast Cancer Metastasis via TNFR2–NF‐κB Signaling and Tumor Microenvironment Remodeling

open access: yesAdvanced Science, EarlyView.
SOX30 drives triple‐negative breast cancer (TNBC) metastasis through a dual mechanism: direct activation of the TNFR2/NF‐κB signaling cascade and subsequent CCL20‐mediated recruitment of tumor‐associated macrophages (TAMs) into the tumor microenvironment.

Randomized preclinical study of machine perfusion in vascularized composite allografts

open access: yesBJS (British Journal of Surgery), EarlyView., 2020
This study was designed to identify the optimum machine perfusion parameters for preservation of limbs before transplantation, and determine whether this was better than cold storage. Normothermic machine perfusion at a pressure of 70 mmHg (NMP‐70) provided superior preservation to cold storage after transplantation.

Spatiotemporally Controlled Sequential Chemo‐Immunotherapy Activates Pyroptosis for Robust Anti‐Tumor Immunotherapy

open access: yesAdvanced Science, EarlyView.
A glutathione and ultrasound dual‐responsive cerasome achieves sequential co‐delivery of gemcitabine and BMS1166 in tumors. Chemotherapy priming followed by on‐demand PD‐L1 blockade synergistically amplifies anti‐tumor immunity, inhibiting primary tumor growth, distant metastasis and inducing durable immune memory.

Remote Desaturation of Unprotected Amines and C─H Amination of Alkanes by Polarity‐Matched N‐Radical Cations

open access: yesAngewandte Chemie, EarlyView.
Highly electrophilic N‐radical cations enable efficient and selective H‐atom transfer (HAT) of unprotected amines. In this exceedingly practical strategy, simple CuCl catalyzes an interrupted Hofmann–Löffler–Freytag (HLF) reaction to afford δ desaturated amines, aza‐heterocycles, and C─H aminated alkanes without protecting groups.
