Gastric carcinoma is frequent, particularly in China, and therapy is often inefficient. Because cancer cells are partly or mainly dependent on glycolysis to generate adenosine triphosphate ATP (Warburg effect) and/or to produce precursors (of lipid, nucleotides, etc.) for building new cells, any inhibition of glycolysis may slow down the cell proliferation and/or may kill cells. The antitumor effect of citrate, an anti-glycolytic agent inhibiting phosphofructokinase (PFK) was tested on two human gastric carcinoma cell lines. »

We previously reported novel quinuclidinone analogs that showed both additive and synergistic cytotoxicity in lung cancer cells. We aimed at understanding the mechanism of these analogs and also their cytotoxic effect on normal cells. The effects of these analogs were studied in response to gamma radiation in H1299 human large cell lung carcinoma cells that are null for p53, normal lung epithelial cell line (NL-20) and H1299 cells stably transfected with p53. »

BEZ235 is a dual phosphatidylinositol 3-kinase (PI(3)K)/mammalian target of rapamycin (mTOR) inhibitor that is orally available and that has been shown to be effective in several malignancies in vitro. Recently, BEZ235 entered clinical trials for solid tumors. We aimed at investigating if BEZ235 is effective in lung cancer cell lines. »

The influence of human prolactin (hPRL) on the development of breast and other types of cancer is well established. Little information, however, exists on the effects of hPRL on squamous cell carcinomas of the head and neck (SCCHNs). »

Head-and-neck cancer (HNC) is the eighth most common malignancy worldwide. It is often diagnosed late due to a lack of screening methods and overall cure is achieved in <50% of patients. Head-and-neck cancer sufferers often develop a second primary tumour that can affect the entire aero-digestive tract, mostly HNC or lung cancer (LC), making lifelong follow-up necessary. »

The clinico-pathological and molecular heterogeneity of epithelial ovarian cancer (EOC) complicates its early diagnosis and successful treatment. Highly aneuploid tumours and the presence of ascitic fluids are hallmarks of EOC. Two microcephaly-associated proteins, abnormal spindle-like microcephaly-associated protein (ASPM) and microcephalin, are involved in mitosis and DNA damage repair. Their expression is deregulated at the RNA level in EOC. Here, ASPM and microcephalin protein expression in primary cultures established from the ascites of patients with EOC was determined and correlated with clinical data to assess their suitability as biomarkers. »

Various constituents of the olive tree (Olea europaea) have been traditionally used in the treatment of infection, inflammation, prevention of chronic diseases, cardiovascular disorders and cancer. The anticancer potential of dry olive leaf extract (DOLE) represents the net effect of multilevel interactions between different biologically active compounds from the extract, cancer cells and conventional therapy. »

Prostate cancer (PCa) is the most common cancer in the adult male, and benign prostatic hyperplasia (BPH) represents the most frequent urologic diagnosis in elderly males. Recent data suggest that prostatic inflammation is involved in the pathogenesis and progression of both conditions. »

Although prostate cancer is commonly diagnosed, few risk factors for high-grade prostate cancer are known and few prevention strategies exist. Statins have been proposed as a possible treatment to prevent prostate cancer. »

Treatment options for patients with low risk prostate cancer include radical prostatectomy, radiation therapy, and active surveillance. Among patients treated with radical prostatectomy, prior studies have demonstrated significantly higher biochemical progression rates with surgical delays of 6 months or greater. We determined the impact of surgical delay on radical prostatectomy outcomes specifically in low risk patients. »
