S100 calcium binding protein A8 (S100A8) has been implicated as a prognostic indicator in several types of cancer. However, previous studies are limited in their ability to predict the clinical behavior of the cancer. Here, we sought to identify a molecular signature based on S100A8 expression and to assess its usefulness as a prognostic indicator of disease progression in non-muscle invasive bladder cancer (NMIBC). »
The present study was designed to determine the possibility of acetylbritannilactone (ABL) derivative 5-(5-(ethylperoxy)pentan-2-yl)-6-methyl-3-methylene-2-oxo-2,3,3a,4,7,7a-hexahydrobenzofuran-4-yl 2-(6-methoxynaphthalen-2-yl)propanoate (ABL-N) as a novel therapeutic agent in human breast cancers. »
Chondrosarcoma is a disease that does not respond to conventional cytotoxic chemotherapy and expression of MMP1 is a marker for a poor prognosis. The mechanism of increased MMP1 expression in chondrosarcoma is not completely known. Our goal is to identify molecular pathways that could serve as therapeutic targets. Chondrosarcoma become hypoxic as they grow, are capable of eliciting an angiogenic response, and typically metastasize to the lungs. The present study determined the effect of hypoxia and specifically HIF-1a on expression of CXCR4 and MMP1 and their role in chondrosarcoma cell invasion. »
Pancreatic ductal adenocarcinoma is a lethal disease with a 5−year survival rate of 4% and typically presents in an advanced stage. In this setting, prognostic markers identifying the more agrressive tumors could aid in managment decisions. Insulin−like growth factor 2 mRNA binding protein 3 (IGF2BP3, also known as IMP3 or KOC) is an oncofetal RNA−binding protein that regulates targets such as insulin−like growth factor−2 (IGF−2) and ACTB (beta−actin). »
MicroRNAs (miRNAs) are a new class of naturally occurring, small, non-coding RNAs that regulate protein-coding mRNAs by causing mRNA degradation or repressing translation. The roles of miRNAs in lineage determination and proliferation, as well as the localization of several miRNA genes at sites of translocation breakpoints or deletions, have led to speculation that miRNAs could be important factors in the development or maintenance of the neoplastic state. »
Retinoids, through their cognate nuclear receptors, exert potent effects on cell growth, differentiation and apoptosis, and have significant promise for cancer therapy and chemoprevention. These ligands can determine the ultimate fate of target cells by stimulating or repressing gene expression directly, or indirectly through crosstalking with other signal transducers.

We have previously reported a novel constitutively overexpressed 21 kDa protein in Hodgkin Lymphoma (HL) and aggressive Non-Hodgkin Lymphomas (NHL). The objective of the current study was to 1) identify this protein using two independent methods, 2) study the expression of the protein and its encoding mRNA in reactive lymph nodes, normal lymphocytes and CD34+ bone marrow precursor cells, 3) analyse patterns of expression of the protein in tissue microarrays assembled from a large number of diagnostic clinical biopsies from patients with HL, and 4) determine the copy number variation and mutation status of the encoding gene in HL cell lines. »
Symptom control is an important consideration in the choice of treatment for patients with recurrent and/or metastatic squamous cell carcinoma of the head and neck (SCCHN). Patients who demonstrate objective tumour responses to platinum-based chemotherapy are more likely to have symptom relief than those who do not have such responses. A phase III trial (EXTREME) showed that adding the epidermal growth factor receptor (EGFR)-targeting IgG1 monoclonal antibody cetuximab to first-line platinum-based chemotherapy significantly prolongs progression-free and overall survival and increases response rate compared with platinum-based chemotherapy alone. We report here the case of a 60-year old female with recurrent squamous cell carcinoma of the gum who had rapid palliation of symptoms and reduction of facial disease mass following treatment with a combination of carboplatin/5-fluorouracil (5-FU) and cetuximab. »
Oral Cancer Overexpressed 1 (ORAOV1) is a candidate protooncogene locating on 11q13. Recent studies show that ORAOV1 acts as a primary driving force behind 11q13 gene amplification and plays a functional role in the tumorigenesis in a variety of human squamous cell carcinomas (SCCs). According to the results of molecular cytogenetic methods, 11q13 was characterized to be a high-level and recurrent amplification chromosomal site in cervical cancers. Up till now, the role of ORAOV1 in cervical cancer is unknown. The purpose of this study is to elucidate the function of ORAOV1 in cervical cancer cell growth by studying its roles in HeLa cells using small interfering RNA. »
FLAIR and T2 weighted MRIs are used based on institutional preference to delineate high grade gliomas and surrounding edema for radiation treatment planning. Although these sequences have inherent physical differences there is limited data on the clinical and dosimetric impact of using either or both sequences. »
