Article Abstract
Molecular determinants of KRAS(G12C)inhibitor efficacy in KRAS-mutated non-small-cell lung cancer (NSCLC) remain poorly characterized. Here we report one of the largest integrated analyses to date of sotorasib clinical efficacy biomarkers from the phase 2 CodeBreaK 100 and phase 3 CodeBreaK 200 studies. We reveal differential sotorasib activity and relative benefit compared to docetaxel across KRAS-mutated NSCLC co-mutational subsets and transcriptional subtypes. We also identify low expression of TTF1 and KEAP1 co-mutations/NRF2 activation as major determinants of sotorasib anti-tumor efficacy and adverse prognostic features. Exploratory analyses highlight potential tumor cell-extrinsic contributors to sotorasib anti-tumor activity and suggest that early on-treatment clearance of KRAS- circulating tumor DNA may refine clinical response prediction algorithms. Our findings advance precision medicine for patients with KRAS-mutated NSCLC and establish a framework for patient stratification and selection for treatment intensification with rationally applied therapeutic combinations.

Protein profiles and associated biological pathways among different etiologies of chronic kidney disease: new insights from DAPA-CKD.
Nephrol Dial Transplant

Department of Clinical Pharmacy and Pharmacology, University Medical Center Groningen, University of Groningen, Groningen, The Netherlands.
Background: We investigated circulating protein profiles and molecular pathways among various chronic kidney disease (CKD) etiologies to study its underlying molecular heterogeneity.
Methods: We conducted a proteomic biomarker analysis in the DAPA-CKD trial recruiting adults with and without type 2 diabetes with an eGFR of 25 to 75 mL/min/1.73m2 and a UACR of 200 to 5000 mg/g.
State-Dependent Dynamic Communication Networks in a Pentameric Ligand-Gated Ion Channel.

Pentameric ligand-gated ion channels control synaptic neurotransmission via an allosteric mechanism, whereby agonist binding induces global protein conformational changes that open an ion-conducting pore. For the proton-activated bacterial () ligand-gated ion channel (GLIC), high-resolution structures are available in multiple conformational states. We used a library of atomistic molecular dynamics (MD) simulations to study conformational changes and to perform dynamic network analysis to elucidate the communication pathways underlying the gating process.

Despite significant advancements in the treatment of non-small cell lung cancer (NSCLC) using conventional therapeutic methods, drug resistance remains a major factor contributing to disease recurrence. In this study, we aimed to explore the potential benefits of combining PI3K inhibition with Cisplatin in the context of NSCLC-derived A549 cells. Human non-small cell lung cancer A549 cells were cultured and treated with BKM120, cisplatin, or their combination.
