In situ RAS:RAF binding correlates with response to KRASG12C inhibitors in KRASG12C--mutant non-small cell lung cancer.
Clin Cancer Res
January 2025
Moffitt Cancer Center, Tampa, Florida, United States.
Purpose: Therapeutic efficacy of KRASG12C(OFF) inhibitors (KRASG12Ci) in KRASG12C-mutant non-small cell lung cancer (NSCLC) varies widely. The activation status of RAS signaling in tumors with KRASG12C mutation remains unclear, as its ability to cycle between the active GTP-bound and inactive GDP-bound states may influence downstream pathway activation and therapeutic responses. We hypothesized that the interaction between RAS and its downstream effector RAF in tumors may serve as indicators of RAS activity, rendering NSCLC tumors with a high degree of RAS engagement and downstream effects more responsive to KRASG12Ci compared to tumors with lower RAS---RAF interaction.

University of Colorado Denver School of Medicine, Aurora, Colorado, United States;
Whether early life acetaminophen (APAP) exposures injure the developing lung is controversial. We sought to correlate murine pulmonary developmental expression profiles of to susceptibility to APAP exposure. P14 C57BL/6 mice were exposed to APAP (140 mg/kg x 1, IP) and assessed for evidence of a histologic, metabolic, functional, and/or transcriptional pulmonary response.

Self-efficacy is tightly intertwined with person-centered care and correlates with engaging in self-care behaviors, an important part of hypertension treatment. Evidence indicates that e-Health-based self-management interventions could increase self-efficacy. The objectives of this study were to investigate whether an intervention with a person-centered approach supported by e-Health technology can impact self-efficacy.

Objective: Although studies have examined changes in C-reactive protein (CRP) during pulmonary exacerbations (PEX) in people with cystic fibrosis (PwCF), few have evaluated CRP profiles across age groups. Here, we characterize age-related CRP responses to PEX treatment.
Methods: We measured CRP concentrations at the beginning and end of intravenous (IV) antibiotic therapy for PEX in 100 pediatric and 147 adult PwCF at 10 US CF Centers.
