Trastuzumab rezetecan, a HER2-directed antibody-drug conjugate, in patients with advanced HER2-mutant non-small-cell lung cancer (HORIZON-Lung): phase 2 results from a multicentre, single-arm study.

Background: Trastuzumab rezetecan (also known as SHR-A1811) is a novel antibody-drug conjugate consisting of a humanised HER2-directed monoclonal antibody, cleavable tetrapeptide-based linker, and DNA topoisomerase I inhibitor. In the phase 1 portion of this phase 1/2 study, trastuzumab rezetecan showed preliminary anti-tumour activity and a favourable safety profile in patients with HER2-mutant non-small-cell lung cancer (NSCLC). We present phase 2 results from the study, which aimed to further evaluate the activity and safety of trastuzumab rezetecan at the recommended dose.

Background: In the phase 3 ORIENT-11 study, sintilimab plus pemetrexed-platinum provided statistically significant longer overall survival and progression-free survival versus placebo plus pemetrexed-platinum as first-line treatment in patients with locally advanced or metastatic non-squamous non-small cell lung cancer (NSCLC). Here, we report the patient-reported outcomes (PRO) analysis findings in ORIENT-11.

Methods: PROs were measured using the European Organization for Research and Treatment of Cancer Quality of Life of Cancer Patients Questionnaire Core 30 items (EORTC QLQ-C30) and the Lung Cancer Symptom Scale (LCSS) questionnaire.

Disentangling activity-stability trade-off in the catalytic degradation of malodorous sulfur-containing VOCs driven by active sites' self-dynamic evolution.

The catalytic degradation of malodorous sulfur-containing volatile organic compounds (S-VOCs), especially methanethiol (CHSH), faces an enormous challenge in striking a balance between activity and stability. Herein, we develop the time-tandem and spatial-extended strategy for synthesizing t-MoO/meso-SiO nano-reactor-type catalysts and reveal the migration and transformation behaviors of both carbon and sulfur species at the mesoscopic scale to break the catalytic CHSH activity and stability trade-off. The dynamic evolution of active centers from initial oxygen sites and acid sites to sulfur vacancies in MoS during the reaction process as well as the formation of a new dimethyl disulfide (CHSSCH) reaction pathway are identified as the main reason for the catalysts' superior activity and sulfur resistance.

Then, cell viability, apoptosis, reactive oxygen species (ROS) levels, pro-inflammatory factors, and expression of the related proteins SIRT1, HMGB1, VEGF, and CD31 were assayed by a series of cell biology methods.

Sheets Copper-Cobalt Graphitic Carbon Nitride Dual Single-Atom Catalysts for the Epoxidation of Styrene.

Dual single-atom catalysts have attracted considerable research interest due to their higher metal atom loading and more flexible active sites compared to single-atom catalysts (SACs). We pioneered the one-step synthesis of sheets copper-cobalt graphitic carbon nitride dual single-atom (S-Cu/Co-g-CN) using folding fan-shaped aluminum foil as a template, and used them as catalysts in the epoxidation of styrene respectively. Through XAFS (X-ray Absorption Fine Structure) and other characterizations, it is found that Cu and Co single atoms are stabilized separately on g-CN via coordination with nitrogen (N), hindered the ordered growth of sheets, and formed more pore structures, which not only increased more catalytically active sites, but also effectively prevented the flakes re-aggregate during the catalytic process.

Nuclear Overexpression of SAMHD1 Induces M Phase Stalling in Hepatoma Cells and Suppresses HCC Progression by Interacting with the Cohesin Complex.

Emerging evidence suggests that the sterile alpha-motif (SAM) and histidine-aspartate (HD) domain-containing protein 1 (SAMHD1) is implicated in various cancers, including hepatocellular carcinoma (HCC). However, its precise role in tumor cells and the underlying mechanisms remain unclear. This study aimed to investigate the expression patterns, prognostic values, and functional role of SAMHD1 in HCC progression.

Sunvozertinib monotherapy in EGFR tyrosine kinase inhibitor-resistant non-small cell lung cancer with EGFR mutations.

Background: Multiple agents can be used to treat patients with EGFR mutated non-small cell lung cancer (NSCLC) who develop resistance to EGFR tyrosine kinase inhibitors (TKIs), but the clinical outcome was not satisfactory, especially in patients with multiple lines of prior therapies. Therefore, there is an unmet medical need for these patients. Sunvozertinib is an oral, potent, irreversible, and mutant-selective EGFR TKI targeting EGFR mutations with weak activity against wild-type EGFR.

Controllable Microwave Heating for Energy-Efficient and Universal Synthesis of Atomically Dispersed Metals on Nitrogen-Doped Carbon Nanofibers.

Carbon-supported single-atom catalysts (SACs) have shown great potential in electrocatalysis, whereas traditional synthesis methods typically involve energy-intensive carbonization processes and unfavorable atomic migration and aggregation. Herein, an energy-efficient and universal strategy is developed to rapidly fabricate various SACs on nitrogen-doped hierarchically porous carbon nanofibers (M-TM/NPCNFs, TM = Fe, Co, Ni, FeCo, and FeNi) by electrospinning and controllable microwave heating technique. Such microwave heating technique enables an ultrafast heating rate (ramping to 900 °C in 5 min) to greatly suppress the random migration and aggregation of metal species.
