Thrombomodulin (TM, also known as CD141), which functions as an anticoagulant, is widely expressed on cell surface of a variety of cell types, including human blood cells as well as certain immune cells. To determine whether TM could be a potential marker for OSCC diagnosis as well as a molecular target for OSCC therapy, we examined the expression of TM in an oral cancer tissue microarray with 153 oral cancer tissues. Further, we also analyzed the expression of TM on DCs of 36 OSCC patients and 36 healthy donors...

Hexavalent chromium compounds are well-established respiratory carcinogens used in industrial processes. While inhalation exposure constitutes an occupational risk affecting mostly chromium workers, environmental exposure from drinking water is a widespread gastrointestinal cancer risk, affecting millions of people throughout the world. Cr(VI) is genotoxic, forming protein-Cr-DNA adducts and silencing tumor suppressor genes, but its mechanism of action at the molecular level is poorly understood. Our prior work using FAIRE showed that Cr(VI) disrupted the binding of transcription factors CTCF and AP-1 to their cognate chromatin sites...

BACKGROUND: Esophageal cancer is one of the worst malignant digestive neoplasms with poor treatment outcomes. Definitive concurrent chemoradiotherapy (CRT) has become the standard nonsurgical treatment option for locally advanced esophageal cancer. The chemotherapeutic drugs 5-fluorouracil and cisplatin have been most commonly used in CRT of esophageal cancer. However, radiotherapy combined with 5-FU/cisplatin often delivers severe toxicity to patients. S-1 as an oral chemotherapeutic drug exhibits higher anti-tumor activity, less adverse effects, and better biological availability...

Non-small cell lung cancer (NSCLC) accounts for most cases of lung cancer. The peel oil of mandarin Citrus reticulata Blanco cv. Dancy (MPO) is a natural source of essential oils and carotenoids. Volatile and non-volatile lipid compounds were characterized by chromatographic methods. We demonstrate that MPO causes a dose-dependent growth inhibition of NSCLC model cells (A549) in culture and tumour growth in vivo of the same cells implanted in nude mice fed with MPO-supplemented diets. MPO induced cell cycle arrest mainly at the G0/G1 phase and reduced the amount of membrane-bound Ras protein along with apoptosis induction...

Effective treatment of advanced metastatic disease remains the primary challenge in the management of inoperable pancreatic cancer. Current therapies such as oxaliplatin (OxPt)-based chemotherapy regimens (FOLFIRINOX) provide modest short-term survival improvements, yet with significant toxicity. Photodynamic therapy (PDT), a light-activated cancer therapy, demonstrated clinical promise for pancreatic cancer treatment and enhances conventional chemotherapies with non-overlapping toxicities. This study investigates the capacity of neoadjuvant PDT using a clinically-approved photosensitizer, benzoporphyrin derivative (BPD, verteporfin), to enhance OxPt efficacy in metastatic pancreatic cancer...

CD147, encoded by BSG , is a highly glycosylated transmembrane protein that belongs to the immunological superfamily and expressed on the surface of many types of cancer cells. While CD147 is best known as a potent inducer of extracellular matrix metalloproteinases, it can also function as a key mediator of inflammatory and immune responses. To systematically elucidate the function of CD147 in cancer cells, we performed an analysis of genome-wide profiling across the Cancer Cell Line Encyclopedia (CCLE). We showed that CD147 mRNA expression was much higher than that of most other genes in cancer cell lines...

We previously found that the serum level of fucosylated haptoglobin (Fuc-Hpt) was significantly increased in pancreatic cancer patients. To delineate the mechanism underlying this increase and develop a simple detection method, we set out to generate a monoclonal antibody (mAb) specific for Fuc-Hpt. After multiple screenings by enzyme-linked immunosorbent assay (ELISA), a 10-7G mAb was identified as being highly specific for Fuc-Hpt generated in a cell line as well as for Hpt derived from a pancreatic cancer patient...

Testicular germ cell tumor (TGCT), the most common cancer in men aged 18 to 45 years, has a strong heritable basis. Genome-wide association studies (GWAS) have proposed single nucleotide polymorphisms (SNPs) at a number of loci influencing TGCT risk. To further evaluate the association of recently proposed risk SNPs with TGCT at 2q14.2, 3q26.2, 7q36.3, 10q26.13 and 15q21.3, we analyzed genotype data on 3,206 cases and 7,422 controls. Our analysis provides independent replication of the associations for risk SNPs at 2q14...
