Tenascin C has been recently suggested as a tumor marker, however, its levels in serum has been evaluated only in patients with head and neck cancer and melanoma. In this study, we investigated Tenascin C expression in blood samples from colorectal and bladder cancer patients, compared to that of epidermal growth factor receptor (EGFR), a known circulating(More)
UDP-glucuronosyltrasferases (UGTs) are detoxifying enzymes, which convert endogenous substrates, dietary constituents and potential carcinogens to inactive hydrophilic glucuronides. Although the liver is considered the most important organ for glucuronidation, UGTs are also expressed in extrahepatic tissues. Since UGTs may be important to protect cells from(More)
Expression of genes such as cytokeratin 19 (CK19), cytokeratin 20 (CK20) and epidermal growth factor receptor (EGFR) has been investigated at mRNA level in peripheral blood of carcinoma patients to detect the presence of circulating tumor cells (CTC). We performed this study because recent literature emphasizes that the importance of CK19, 20 and EGFR mRNAs(More)
Recent data suggest that new treatment options for superficial bladder cancer are necessary, owing to the high recurrence rate after conventional treatment, especially in T1G3 and Bacillus Calmette-Guerin-refractory patients. Phase I and II studies have demonstrated that gemcitabine may represent a candidate for intravesical therapy in superficial bladder(More)
Background: Polymerase chain reaction (PCR) is a molecular biology technique that can detect a single metastatic cell in 106 to 107 normal cells. Its use has been proposed as an additional new method for the detection of malignant melanoma nodal metastases in the sentinel lymph node (SLN) to improve the detection rate guaranteed so far by standard histology(More)
Breast cancer is characterized by molecular heterogeneity, and four major breast cancer subtypes have been identified, each characterized by significant differences in survival, prognosis, and response to therapy. We have studied the effects of docetaxel treatment on apoptosis and survivin expression in four breast cancer cell lines: MCF7 (luminal A:(More)
Recent studies have demonstrated that antineoplastic activity of Cox-2 inhibitors may depend on targets other than Cox: among those, nuclear factor kappaB (NFkappaB) seems the most promising. Although preclinical studies have suggested that aspirin and Cox-2 inhibitors may influence the progression of lung cancer, the molecular mechanisms of these(More)
Inhibitors of kinesin spindle protein Eg5 are characterized by pronounced antitumor activity. Our group has recently synthesized and screened a library of 1,3,4-thiadiazoline analogues with the pharmacophoric structure of K858, an Eg5 inhibitor. We herein report the effects of K858 on four different breast cancer cell lines: MCF7 (luminal A), BT474 (luminal(More)
Antimitotic agents are widely used in cancer chemotherapy but the numerous side effects and the onset of resistance limit their clinical efficacy. Therefore, with the purpose of discovering more selective and efficient anticancer agents to be administered alone or in combination with traditional drugs, we synthesized a large library of 1,3,4-thiadiazoline(More)
Background: Recently reverse transcriptase-polymerase chain reaction (RT-PCR) has been proposed as a new sensitive method for the detection of submicroscopic melanoma nodal metastases. Sentinel lymph node (SLN) status is considered the most important prognostic factor for melanoma patients. Thus, in recent years, melanoma research has been focused on(More)
