RNA-seq of vastus lateralis muscle biopsies of newly diagnosed treatment-naïve NSCLC patients with cachexia and age-matched and sex-matched healthy controls

Cancer cachexia, highly prevalent in lung cancer, is a debilitating syndrome characterized by involuntary loss of skeletal muscle mass, and is associated with poor clinical outcome, decreased survival and negative impact on on tumor therapy. Here we sought to identify the muscle gene profile and pathways regulated in cachexia. Vastus lateralis muscle was obtained of newly diagnosed treatment-naïve NSCLC patients with cachexia (n = 8) and matched healthy controls (n = 8). Self-reported weight loss and body composition measurements defined cachexia status. RNA sequencing was performed on the Illumina NovasSeq 6000.
