BACKGROUND Recent prospective clinical trials of low molecular weight heparins (LMWHs) have demonstrated that these agents may provide significant advantages in terms of progression-free and overall survival in certain subgroups of cancer patients. The mechanisms of improved survival associated with LMWHs are not known, and may involve direct and/or indirect effects on tumor growth. The purpose...

Objective(s): Program death 1 (PD-1)/ program death-ligand 1 (PD-L1) pathways, as the main inhibitory checkpoints, induce immunosuppression in the tumor microenvironment (TME). Despite the importance of inhibitor checkpoint receptor (ICR) blockers, their outcomes have been limited by the low immune response rate and induced acquired resistance. Pre-existing tumor-speci...

Abstract Objectives The EVI2B (Ecotropic Viral Integration Site 2B) gene encodes a transmembrane glycoprotein pivotal in immunocytes maturation. Recent evidence implicated EV12B’s expression with human colon cancer progression. However, EVI2B’s downstream pathways affecting tumor growth and tumor-infiltrating cells remain unclear. Methods We first studied the diagnostic prognostic value of pan-...

Objective(s): Growing evidences have indicated microRNAs as modulators of tumor development and aggression. On the other hand, a phenomenon known as epithelial-mesenchymal transition (EMT) that indicates a transient phase from epithelial-like features to mesenchymal phenotype is a key player in tumor progression.  In this study, we aimed to assess the potential impacts...

Mature cystic teratoma (MCT) is the most common type of ovarian germ cell tumor occurring in females of reproductive age. It is typically benign, but rare malignant transformations have been reported in 1-2% of the cases. Among a wide variety of malignancies arising in MCTs, high grade lymphomas are the least common. We present a case of a 45- years -old female with a unilateral adnexal ma...

BACKGROUND Despite various attempts at modifying usual treatment modalities, anaplastic thyroid cancer (ATC) is still associated with unfavorable prognosis. Results of preclinical investigations are often of limited transferability to clinical tumor biology. Individualized multimodal treatment regimens, including novel growth-inhibiting drugs, might be a future option. METHODS Tumor tissue, f...

background: the metabolically active tumor cells may be characterized by a pronounced adenosine release that regulates the growth and development of the tumor. consequently, the expression pattern of defined receptor subtypes will be an important determinant for specific effects of adenosine on the control of tumor cell growth. in recent studies, the expression profile, signal transduction, mol...

BACKGROUND/AIM To determine whether Gramicidin S (GS)-nitroxide, JP4-039, esophageal radiation protection protected lung tumors in a transgenic model, LoxP-Stoop-LoxP Kristen Rat Sarcoma Viral oncogene (LSL-K-RAS) mice were administered intra-tracheal- Carbapenem-resistant Enterobacteriaceae (CRE) recombinase, bilateral lung tumors were confirmed at 11 weeks, then thoracic irradiation was deliv...

This study investigated the immunohistochemical staining characteristics of glutathione-S-transferase alpha, pi, mu, theta and p53 in non-small cell lung carcinoma and normal lung tissue from 50 patients. The relationships between expressions of the Glutathione-S-transferase isoenzymes and some clinicopathological features were also examined. Expression of glutathione-S-transferase pi, mu, alph...

p16-mediated inhibition of cancer cell proliferation and tumor suppression have been studied before,; the common consensus is that p16's cell-cycle arrest function plays a primary role in these actions, with some additional apoptotic induction by p16. However, other effects of p16 that may potentially contribute to p16-mediated anti-tumor ability have not been well studied. The emerging data in...
