Cancers, Vol. 11, Pages 1766: Collagen Induces a More Proliferative, Migratory and Chemoresistant Phenotype in Head and Neck Cancer via DDR1 Cancers doi: 10.3390/cancers11111766 Authors: Sook Ling Lai May Leng Tan Robert J. Hollows Max Robinson Maha Ibrahim Sandra Margielewska E. Kenneth Parkinson Anand Ramanathan Rosnah Binti Zain Hisham Mehanna Rachel J. Spruce Wenbin Wei Ivy Chung Paul G. Murray Lee Fah Yap Ian C. Paterson Head and neck squamous cell carcinoma (HNSCC) is the sixth most common cancer worldwide and includes squamous cell carcinomas of the oropharynx and oral cavity. Patient prognosis has remained poor for decades and molecular targeted therapies are not in routine use. Here we showed that the overall expression of collagen subunit genes was higher in cancer-associated fibroblasts (CAFs) than normal fibroblasts. Focusing on collagen8A1 and collagen11A1, we showed that collagen is produced by both CAFs and tumour cells, indicating that HNSCCs are collagen-rich environments. We then focused on discoidin domain receptor 1 (DDR1), a collagen-activated receptor tyrosine kinase, and showed that it is over-expressed in HNSCC tissues. Further, we demonstrated that collagen promoted the proliferation and migration of HNSCC cells and attenuated the apoptotic response to cisplatin. Knockdown of DDR1 in HNSCC cells demonstrated that these tumour-promoting effects of collagen are mediated by DDR1. Our data suggest that specific inhibi...

Abstract The pathogenesis and prognosis of glioblastoma (GBM) remain poorly understood. Mutual exclusivity analysis can distinguish driver genes and pathways from passenger ones. The purpose of this study was to identify mutually exclusive gene sets (MEGSs) that have prognostic value and to detect novel driver genes in GBM. The genomic alteration profile and clinical information were derived from The Cancer Genome Atlas, and the MEGSA method was used to identify the MEGS. Next, we performed survival analysis and constructed a risk prediction model for prognostic stratification. Leave-one-out cross-validation and p...

Abstract Human epididymis protein 4 (HE4) is an available tumor biomarker mainly for detecting ovarian cancer. However, it is unknown whether it can be a novel indicator for diagnosis of diabetic kidney disease (DKD). The aim of this study was to investigate the possibility of serum HE4 as a novel biomarker for DKD in patients with type 2 diabetes mellitus (T2DM). We enrolled 236 patients with T2DM and 82 healthy individuals. Serum HE4 was detected by ARCHITECT i2000 and compared between T2DM patients and healthy controls. The relationships between various variables and HE4 were analyzed by univariate or multivari...

Abstract Flavoproteins and their interacting proteins play important roles in mitochondrial electron transport, fatty acid degradation, and redox regulation. However, their clinical significance and function in esophageal squamous cell carcinoma (ESCC) are little known. Here, using survival analysis and machine learning, we mined 179 patient expression profiles with ESCC in GSE53625 from the Gene Expression Omnibus (GEO) database and constructed a signature consisting of two flavoprotein genes (GPD2 and PYROXD2) and four flavoprotein interacting protein genes (CTTN, GGH, SRC, and SYNJ2BP). Kaplan-Meier analysis re...

taf M Abstract A- and D-ring-modified luotonin-inspired heterocycles have been synthesized and were evaluated for their activity against the viability of four cancer cell lines in vitro, namely, MCF7, HCT116, JURKAT, and NCI-H460. The analysis of results indicated that two of the synthesized derivatives displayed good inhibition against the growth of the human colon cancer HCT116 cell line, with potencies lower than but in the same order of magnitude as camptothecin (CPT). These two luotonin analogues also showed an activity similar to that of the highly potent alkaloid CPT as inhibitors of topoisomerase I and als...

Abstract Neurological diseases particularly Alzheimer's disease (AD), Parkinson's disease (PD), stroke, and epilepsy are on the rise all around the world causing morbidity and mortality globally with a common symptom of gradual loss or impairment of motor behaviour. Striatum, which is a component of the basal ganglia, is involved in facilitating voluntary movement while the cerebellum is involved in the maintenance of balance and coordination of voluntary movements. Dopamine, serotonin, gamma-aminobutyric acid (GABA), and glutamate, to name a few, interact in regulating the excitation and inhibition of motor neuro...

Publication date: Available online 9 December 2019Source: Journal of Theoretical BiologyAuthor(s): Luis F. Ponce, Karina García-Martínez, Kalet LeónAbstractIL-1 system is involved in the induction and maintenance of chronic inflammation associated with several autoimmune diseases and cancer, mainly due to its capacity to promote the secretion of inflammatory mediators. For this reason, several intracellular and extracellular mechanisms for this system have been fixed during the evolution. In spite of the large description of molecular interactions between IL-1 ligands and receptors, little is known abo...

Authors: Galizia G, Auricchio A, de Vita F, Cardella F, Mabilia A, Basile N, Orditura M, Lieto E Abstract PURPOSE: Oncological outcome depends not only on tumor behaviour but also on nutritional and immune-inflammatory host status. Data in gastric cancer are limited. The main aim of this study was to prospectively assess Naples prognostic score (NPS) in gastric cancer patients. NPS was also compared with prognostic nutritional index (PNI), controlling nutritional status (CONUT) score and systemic inflammation score (SIS). METHODS: Overall survival (OS) and complication rates of 415 patients undergoing gastric c...

CONCLUSIONS: These data impose a closer follow-up of smokers and pre-neoplastic cases and the utility of the broadspectrum polymerase chain reaction assay in laryngeal dysplastic and cancer lesions. This study may allow to develop biomarkers for early detection or recurrence surveillance, to identify therapeutic targets, and to begin individualization of treatment based on the biology of these tumours. KEY WORDS: HPV infection, Larynx, Laryngeal chronic hyperplastic inflammation, Squamous cell carcinoma. PMID: 31814599 [PubMed - in process]
