The oncolytic adenovirus dl922-947 replicates selectively within and lyses cells with a dysregulated Rb pathway, a finding seen in >90% human cancers. dl922-947 is more potent than wild type adenovirus and the E1B-deletion mutant dl1520 (Onyx-015). »

Angiopoietin-2 is expressed in prostate cancer (PCa) bone, liver, and lymph node metastases, whereas, its competitor angiopoietin-1 has limited expression in these tissues. Therefore, we hypothesized that the inhibition of angiopoietin-2 activity in PCa will impede angiogenesis, tumor growth, and alter bone response in vivo. »

The aim of this study was to explore the potentiality of beta-catenin, Glut-1 and PTEN proteins as markers for a diagnosis of endometrial intraepithelial neoplasia (EIN). DESIGN: Ten proliferative endometrium, 83 endometrial hyperplasia (59 benign hyperplasia, 24 EIN) and 24 endometrioid adenocarcinoma sections were immunostained for beta-catenin, Glut-1 and PTEN protein expression. »

The progression-free and median survival of patients with advanced ovarian cancer has not appreciably improved over the last decade. Novel targeted therapies, particularly antiangiogenic agents, may potentially improve clinical outcomes in patients with ovarian cancer. This phase II, open-label study evaluated oral pazopanib monotherapy in patients with low-volume recurrent ovarian cancer. »

There is a need for identification of new biomarkers improving our understanding, diagnosis, and follow-up of ovarian cancer. Growth differentiation factor-15 (GDF-15) is a member of the transforming growth factor-beta superfamily, and GDF-15 overexpression has been found in several cancer forms but has not been explored in ovarian cancer. The aim of the study was to explore preoperative plasma concentration and tissue expression of growth differentiation factor (GDF)-15 in ovarian tumors. »

Lactate formation is up-regulated in tumorous cells by lactate dehydrogenase (LDH). High serum LDH level is linked to many malignancies with poorer survival, but tumour LDH-5 has not been well investigated in non-small cell lung cancer (NSCLC). »

Human papillomavirus (HPV) 16/18 infection is associated with nonsmoking lung cancer. In this study, the authors investigated a putative correlation between interleukin (IL)-17 expression and HPV infection in clinical nonsmall cell lung cancer (NSCLC) tissues and examined the effects of HPV infection on a human NSCLC cell line. »

Systemic chemotherapy plays the major role in the management of patients with small cell lung cancer. Cisplatin plus etoposide is the most widely used regimen and is considered as standard in patients with limited disease. »

We previously found the down-expression of SM22 in an experimental animal model of colorectal cancer by performing a proteomic analysis. In this study, we addressed the expression and molecular mechanisms of SM22 in human colorectal cancer. »
