Previously, we described prostate cancer (PCa) detection (83% sensitivity; 67% specificity) in seminal plasma by CE-MS/MS. Moreover, advanced disease was distinguished from organ-confined tumors with 80% sensitivity and 82% specificity. The discovered biomarkers were naturally occurring fragments of larger seminal proteins, predominantly semenogelin 1 and 2, representing endpoints of the ejacul...

In order to explore the effects of hydrogen sulfide (H2S) on myocardial fibrosis in diabetic rats and its underlying mechanisms, intraperitoneal injections of streptozotocin were used to establish the diabetes models and sodium hydrosulfide (NaHS) was used as an exogenous donor of H2S. Eight weeks later, Van Gieson staining was used to observe pathological changes, and basic hydrolysis methods ...

ne heparan sulfate proteoglycan (HSPG) coreceptor is not like another. On page 729, Ding et al. show how two HSPGs, both capable of acting as growth factor coreceptors, have distinct functions on cancer cells. Glypican-1 acts as a long-term growth factor coreceptor, whereas syndecan-1 is shed and helps spread a metasis-promoting proteinase. Upon stimulation with fibroblast growth factor-2 (FGF2...

INTRODUCTION The mechanisms of lung repair and fibrosis in the acute respiratory distress syndrome (ARDS) are poorly known. Since the role of WNT/β-catenin signaling appears to be central to lung healing and fibrosis, we hypothesized that this pathway is activated very early in the lungs after sepsis. METHODS We tested our hypothesis using a three-step experimental design: (1) in vitro lung c...

Muscarinic receptors (CHRM) are overexpressed in colon cancer. To explore a role for muscarinic receptor signaling in colon cancer metastasis, we used human H508 and HT29 colon cancer cells that coexpress epidermal growth factor (ERBB) and CHRM3 receptors. In a wound closure model, following 8-h incubation of H508 cells with 100 μM ACh we observed a threefold increase in cell migration indistin...

Cholangiocarcinoma is a malignant tumor of the liver arising from the bile duct epithelium, accounting for 10-25% of all primary hepatic cancers. The clinical presentation of this tumor is not specific and the diagnosis of early cholangiocarcinoma is difficult, especially in patients with other biliary diseases. Measurement of serum carbohydrate antigen (CA) 19-9 and carcinoembryonic antigen (C...

Although platelet-rich plasma (PRP) is the plasma fraction that contains higher levels of platelet-sequestered proteins such as growth factors and chemokines, it is also abundant in bioactive lipids whose role in wound healing has not been well characterized. This study provides a preliminary evaluation for the effect of the lipid component of PRP on selected genes related to wound healing. Spr...

As a gynecological oncology, ovarian cancer has high incidence and mortality. To study the mechanisms of ovarian cancer, the present study analyzed the GSE37582 microarray. GSE37582 was downloaded from Gene Expression Omnibus and included data from 74 ovarian cancer cases and 47 healthy controls. The differentially-expressed genes (DEGs) were screened using linear models for microarray data pac...

Matrix metalloproteinases (MMPs) contribute to tumor invasion and microenvironment, hence are associated with bladder cancer risk. We therefore, tested whether polymorphisms in MMP genes modify the risk of bladder cancer (BC) and whether smoke exposure modifies this risk. Genotyping was performed in 200 BC patients and 200 controls by polymerase chain reaction-restriction fragment length polymo...
