Abstract
Preclinical tumor models with native tissue microenvironments provide essential tools to understand how heterogeneous tumor phenotypes relate to drug response. Here we present syngeneic graft models of aggressive, metastasis-prone histopathology-specific NSCLC tumor types driven by KRAS mutation and loss of LKB1 (KL): adenosquamous carcinoma (ASC) and adenocarcinoma (AC). We show that subcutaneous injection of primary KL; ASC cells results in squamous cell carcinoma (SCC) tumors with high levels of stromal infiltrates, lacking the source heterogeneous histotype. Despite forming subcutaneous tumors, intravenously injected KL;AC cells were unable to form lung tumors. In contrast, intravenous injection of KL;ASC cells leads to their lung re-colonization and lesions recapitulating the mixed AC and SCC histopathology, tumor immune suppressive microenvironment and oncogenic signaling profile of source tumors, demonstrating histopathology-selective phenotypic dominance over genetic drivers. Pan-ERBB inhibition increased survival, while selective ERBB1/EGFR inhibition did not, suggesting a role of the ERBB network crosstalk in resistance to ERBB1/EGFR. This immunocompetent NSCLC lung colonization model hence phenocopies key properties of the metastasis-prone ASC histopathology, and serves as a preclinical model to dissect therapy responses and metastasis-associated processes.

Abstract
Keratins (K) are intermediate filament proteins important in protection from cellular stress. K8, K18 and K19 are the main components of keratin filaments in colonic epithelia but their role in intestinal diseases remains ambiguous. A function for keratins in intestinal health is supported by the K8-knock-out (K8(-/-)) mouse which manifests an early chronic ulcerative colitis-like inflammatory bowel disease and epithelial hyperproliferation. We tested whether K8(-/-) mice are more susceptible to colorectal cancer (CRC) compared to K8 wild type (K8(+/+)), and K8 heterozygote (K8(+/-)) mice showing increased proliferation but no inflammation. K8(-/-) mice did not develop CRC spontaneously, but had dramatically increased numbers of tumors in the distal colon in the azoxymethane (AOM) and Apc(Min/+) CRC models while neither K8(+/+) nor K8(+/-) mice were susceptible. Upregulation of IL-22 in combination with a complete loss of its negative regulator IL-22BP, and increased downstream STAT3-signaling in K8(-/-) and K8(-/-)Apc(Min/+) colonic epithelia confirmed that the IL-22 pathway, important in inflammation, proliferation and tissue regeneration, was activated. The nearly total loss of IL-22BP correlated with an activated inflammasome leading to increased cleaved caspase-1, and the putative IL-22BP inhibitor, IL-18, as well as a decrease in ALDH1/2. Ablation of K8 in a colorectal cancer cell line similarly resulted in increased IL-18 and decreased ALDH1/2. K8/K18 co-immunoprecipitated with pro-caspase-1, a component of the inflammasome in the colon, which suggests that keratins modulate inflammasome activity and protect the colon from inflammation and tumorigenesis. The K8-null mouse models also provide novel epithelial-derived robust colon-specific CRC models.

Abstract
Targeted delivery of drugs is required to efficiently treat intestinal diseases such as colon cancer and inflammation. Nanoparticles could overcome challenges in oral administration caused by drug degradation at low pH and poor permeability through mucus layers, and offer targeted delivery to diseased cells in order to avoid adverse effects. Here, we demonstrate that functionalization of mesoporous silica nanoparticles (MSNs) by polymeric surface grafts facilitates transport through the mucosal barrier and enhances cellular internalization. MSNs functionalized with poly(ethylene glycol) (PEG), poly(ethylene imine) (PEI), and the targeting ligand folic acid in different combinations are internalized by epithelial cells in vitro and in vivo after oral gavage. Functionalized MSNs loaded with γ-secretase inhibitors of the Notch pathway, a key regulator of intestinal progenitor cells, colon cancer, and inflammation, demonstrated enhanced intestinal goblet cell differentiation as compared to free drug. Drug-loaded MSNs thus remained intact in vivo, further confirmed by exposure to simulated gastric and intestinal fluids in vitro. Drug targeting and efficacy in different parts of the intestine could be tuned by MSN surface modifications, with PEI coating exhibiting higher affinity for the small intestine and PEI–PEG coating for the colon. The data highlight the potential of nanomedicines for targeted delivery to distinct regions of the tissue for strict therapeutic control.
