The association between breast cancer capacity and resources with incidence and mortality in Arizona's low populous counties.

Introduction: While cancer deaths have decreased nationally, declines have been much slower in rural areas than in urban areas. Previous studies on rural cancer service capacity are limited to specific points along the cancer care continuum (eg screening, diagnosis or treatment) and require updating to capture the current rural health landscape since implementation of the 2010 Affordable Care Act in the USA. The association between current rural cancer service capacity across the cancer care continuum and cancer incidence and death is unclear.

Associations of Aspirin and Non-Aspirin Non-Steroidal Anti-Inflammatory Drugs With Colorectal Cancer Mortality After Diagnosis.

Background: Aspirin use reduces colorectal cancer (CRC) incidence, but there is limited evidence regarding associations of aspirin and non-aspirin non-steroidal anti-inflammatory drugs (NSAIDs) with CRC-specific survival.

Methods: This prospective analysis includes women and men from the Cancer Prevention Study-II Nutrition Cohort who were cancer free at baseline (1992 or 1993) and diagnosed with CRC during incidence follow-up through 2015. Detailed information on aspirin and non-aspirin NSAID use was self-reported on questionnaires at baseline, in 1997, and every 2 years thereafter.

Computational-based discovery of FAK FERM domain chemical probes that inhibit HER2-FAK cancer signaling.

The N-terminal FERM domain of focal adhesion kinase (FAK) contributes to FAK scaffolding and interacts with HER2, an oncogene and receptor tyrosine kinase. The interaction between HER2 and FAK drives resistance to FAK-kinase domain inhibitors through FAK Y397 transphosphorylation and FAK re-activation upon inhibition. As such, FAK FERM remains an attractive drug discovery target.

Development of a Fragment-Based Screening Assay for the Focal Adhesion Targeting Domain Using SPR and NMR.

The Focal Adhesion Targeting (FAT) domain of Focal Adhesion Kinase (FAK) is a promising drug target since FAK is overexpressed in many malignancies and promotes cancer cell metastasis. The FAT domain serves as a scaffolding protein, and its interaction with the protein paxillin localizes FAK to focal adhesions. Various studies have highlighted the importance of FAT-paxillin binding in tumor growth, cell invasion, and metastasis.

Development of a High-Throughput Fluorescence Polarization Assay to Detect Inhibitors of the FAK-Paxillin Interaction.

Focal adhesion kinase (FAK) is a promising cancer drug target due to its massive overexpression in multiple solid tumors and its critical role in the integration of signals that control proliferation, invasion, apoptosis, and metastasis. Previous FAK drug discovery and high-throughput screening have exclusively focused on the identification of inhibitors that target the kinase domain of FAK. Because FAK is both a kinase and scaffolding protein, the development of novel screening assays that detect inhibitors of FAK protein-protein interactions remains a critical need.

High resolution crystal structure of the FAK FERM domain reveals new insights on the Druggability of tyrosine 397 and the Src SH3 binding site.

Background: Focal Adhesion Kinase (FAK) is a major cancer drug target that is involved in numerous aspects of tumor progression and survival. While multiple research groups have developed ATP-competitive small molecule inhibitors that target the kinase enzyme, recent attention has been focused on the FAK FERM (Band 4.1, Ezrin, Radixin, Moesin) domain that contains key residue Y397 and contributes to many protein-protein interactions.

Surgeon-Authored Virtual Laparoscopic Adrenalectomy Module Is Judged Effective and Preferred Over Traditional Teaching Tools.

Objective: The study assesses user acceptance and effectiveness of a surgeon-authored virtual reality (VR) training module authored by surgeons using the Toolkit for Illustration of Procedures in Surgery (TIPS).

Oncogenic Receptor Tyrosine Kinases Directly Phosphorylate Focal Adhesion Kinase (FAK) as a Resistance Mechanism to FAK-Kinase Inhibitors.

Focal adhesion kinase (FAK) is a major drug target in cancer and current inhibitors targeted to the ATP-binding pocket of the kinase domain have entered clinical trials. However, preliminary results have shown limited single-agent efficacy in patients. Despite these unfavorable data, the molecular mechanisms that drive intrinsic and acquired resistance to FAK-kinase inhibitors are largely unknown.

Efficacy of focal adhesion kinase inhibition in non-small cell lung cancer with oncogenically activated MAPK pathways.

Background: Focal adhesion kinase (FAK) is overexpressed in many types of tumours, including lung cancer. Y15, a small molecule which inhibits Y397 FAK autophosphorylation, decreases growth of human neuroblastoma, breast and pancreatic cancers. In this study, we investigated the in vitro and in vivo effects of Y15, and the underlying mechanism on non-small cell lung cancer cells.

Synthesis and bioactivity of a Goralatide analog with antileukemic activity.

Down-regulation of ALDH1A3, CD44 or MDR1 sensitizes resistant cancer cells to FAK autophosphorylation inhibitor Y15.

Purpose: Focal adhesion kinase is an important survival signal in cancer. Recently, we demonstrated that the autophosphorylation inhibitor of FAK, Y15, effectively inhibited cancer cell growth. We detected many cancer cell lines sensitive to Y15 and also detected several cell lines such as colon cancer Lovo-1 and thyroid K1 more resistant to Y15.

A FAK scaffold inhibitor disrupts FAK and VEGFR-3 signaling and blocks melanoma growth by targeting both tumor and endothelial cells.

Melanoma has the highest mortality rate of all skin cancers and a major cause of treatment failure is drug resistance. Tumors heterogeneity requires novel therapeutic strategies and new drugs targeting multiple pathways. One of the new approaches is targeting the scaffolding function of tumor related proteins such as focal adhesion kinase (FAK).

Pharmacokinetic analysis of the FAK scaffold inhibitor C4 in dogs.

Inhibition of focal adhesion kinase-vascular endothelial growth factor receptor 3 complex by C4 was previously shown to reduce tumor growth alone and synergistically with other chemotherapeutic agents in animal tumor models. Single and multiple dose IV and oral dosing studies were performed in dogs to determine C4 pharmacokinetics. C4 was administered to 4 dogs at 1.

High focal adhesion kinase expression in breast carcinoma is associated with lymphovascular invasion and triple-negative phenotype.

Background: Focal adhesion Kinase (FAK) is a nonreceptor protein tyrosine kinase that is overexpressed in tumors and plays a significant role in tumor survival and metastasis. The purpose of the study is to perform correlation of FAK expression with patient prognostic factors using tissue microarrays (TMA) samples.

Methods: We analyzed FAK expression by immunohistochemical staining in 196 breast primary tumor samples from stage II-IV patients and in 117 metastatic tissues matched to the primary tumors using TMA that were stained with FAK monoclonal antibody.

FAK inhibition with small molecule inhibitor Y15 decreases viability, clonogenicity, and cell attachment in thyroid cancer cell lines and synergizes with targeted therapeutics.

Focal adhesion kinase (FAK) is up-regulated in thyroid cancer and small molecule FAK scaffolding inhibitor, Y15, was shown to decrease cancer growth in vitro and in vivo. We sought to test the effectiveness of Y15 in thyroid cancer cell lines, profile gene expression with Y15 compared with clinical trial FAK inhibitor PF-04554878, and use Y15 in novel drug combinations. Cell viability was decreased in a dose dependent manner in four thyroid cancer cell lines with Y15 and with higher doses in PF-04554878.
