Abstract The clinical efficacy of epidermal growth factor receptor (EGFR) kinase inhibitors is limited by the development drug resistance. irreversible EGFR inhibitor WZ4002 effective against most common mechanism resistance mediated T790M mutation. Here, we show, in multiple complementary models, that to develops through aberrant activation extracellular signal-regulated (ERK) signaling caused either an amplification mitogen-activated protein 1 (MAPK1) or downregulation negative regulators...

The fecal microbiota is a rich source of biomarkers that have previously been shown to be predictive numerous disease states. Less well studied the effect immunomodulatory therapy on and its role in response therapy. This study explored associations between therapeutic Crohn's (CD) patients treated with ustekinumab (UST; Stelara) phase 2 CERTIFI study. Using stool samples collected over course 22 weeks, composition these subjects' bacterial communities was characterized by sequencing 16S...

Crohn's disease and ulcerative colitis are driven by both common distinct underlying mechanisms of pathobiology. Both diseases, exhibit heterogeneity underscored the variable clinical responses to therapeutic interventions. We aimed identify disease-driving pathways classify individuals into subpopulations that differ in their pathobiology response treatment. applied hierarchical clustering enrichment scores derived from gene set variation analysis signatures representative various...

Summary The molecular basis of sarcoidosis phenotype heterogeneity and its relationship to effective treatment have not been elucidated. Peripheral samples from subjects who participated in a Phase II study golimumab [anti-tumour necrosis factor (TNF)-α] ustekinumab [anti-interleukin (IL)−12p40] were used measure the whole blood transcriptome levels serum proteins. Differential gene protein expression analyses explore differences between phenotypes as defined by extent organ involvement....

Introduction: Heterogeneity in IBD patient populations is widely cited as the main barrier to efficient clinical trials and development of therapies with high efficacy. We others hypothesize that phenotypic heterogeneity a direct result molecular disease-driving pathways. present an approach not extensively explored for defining manner independent known biology. Methods: Whole genome transcriptomic data was generated colonic biopsies from 217 moderately severely active ulcerative colitis...

Introduction: CD and UC are thought to be driven by both common distinct pathobiology. Heterogeneity in diseases is underscored variability clinical responses therapeutic interventions. To explore this heterogeneity we aimed classify individuals into subgroups based on their pathobiology assess the relationship of these response anti-TNF. Methods: Colonic biopsies from healthy volunteers (HV), patients were analyzed performing hierarchical clustering enrichment scores (ES) calculated a...
