For locally advanced and metastatic head and neck squamous cell carcinoma (HNSCC), the current clinical use of Cetuximab in chemo/radiotherapy protocols is often associated to severe systemic toxicity. Here we report in vitro data in human FaDu pharynx SCC cells, showing that inactive concentrations of biotinylated Cetuximab (bCet) become active upon anchorage to AvidinOX on the surface of tumor cells. AvidinOX-anchored bCet induces apoptosis and DNA damage as well as specific inhibition of signaling, degradation and abrogation of nuclear translocation of EGFR. In the mouse model of FaDu cancer, we show that intra-tumor injection of AvidinOX allows anti-tumor activity of an otherwise inactive, intraperitoneally delivered, low dose bCet. Consistently with in vitro data, in vivo tumor inhibition is associated to induction of apoptosis, DNA damage and reduced angiogenesis. AvidinOX is under clinical investigation for delivering radioactive biotin to inoperable tumors (ClinicalTrials.gov ) and present data support its use for the local treatment of HNSCC in combination with systemic administration of low dose bCet.

According to the classical view, the cerebellum has long been confined to motor control physiology; however, it has now become evident that it exerts several non-somatic features other than the coordination of movement and is engaged also in the regulation of cognition and emotion. In a previous diffusion-weighted imaging-constrained spherical deconvolution (CSD) tractography study, we demonstrated the existence of a direct cerebellum-hippocampal pathway, thus reinforcing the hypothesis of the cerebellar role in non-motor domains. However, our understanding of limbic-cerebellar interconnectivity in humans is rather sparse, primarily due to the intrinsic limitation in the acquisition of in vivo tracing. Here, we provided tractographic evidences of connectivity patterns between the cerebellum and mammillary bodies by using whole-brain CSD tractography in 13 healthy subjects. We found both ipsilateral and contralateral connections between the mammillary bodies, cerebellar cortex, and dentate nucleus, in line with previous studies performed in rodents and primates. These pathways could improve our understanding of cerebellar role in several autonomic functions, visuospatial orientation, and memory and may shed new light on neurodegenerative diseases in which clinically relevant impairments in navigational skills or memory may become manifest at early stages. 相似文献

Disulfiram (DSF) is an aldehyde dehydrogenase inhibitor currently used for the treatment of alcoholism. Here, we show that multiple myeloma (MM) cell lines and primary cells from newly diagnosed and relapsed/resistant patients affected by MM, acute myeloid and lymphoblastic leukemia are significantly sensitive to DSF alone and in combination with copper. These effects are present at doses lower than those achievable in vivo after DSF standard administration. The cytotoxic effect achieved by this treatment is comparable to that obtained by conventional chemotherapy and is absent in normal hematopoietic cells. In addition, we found that DSF plus copper induces loss of mitochondrial membrane potential, triggers reactive oxygen species (ROS) production and activates executioner caspases. DSF-copper-induced apoptosis and caspases activation are strongly reversed by antioxidant N-acetylcysteine, thus indicating a critical role of ROS. These results might suggest the use of the old drug DSF, alone or in combination with copper, in the treatment of hematological malignancies. 相似文献

The aim of this study was to investigate the role of biomarkers CA125, HE4, and CA72.4 at diagnosis and throughout the follow-up in patients with epithelial ovarian cancer (EOC). Thirty-nine patients with EOC were deemed eligible, and 20 were followed up. CA125, HE4, and CA72.4 serum levels were determined for all patients at initial diagnosis of EOC. Among these patients, the number of cases with an elevated level of each individual marker was CA125 77?%, HE4 85?%, and CA72.4 72?%. A statistically significant difference was observed between the level of HE4 when compared to CA72.4 (p?<?0.02). In the follow-up phase, we observed tumor marker levels fluctuating according to response to chemotherapy. When combining two out of the three biomarkers together, we observed increased values of CA125 and CA72.4 in 55?% of the patients, increased values of CA125 and HE4 in 65?% of the patients, and finally increased HE4 and CA72.4 in 75?% of the patients. A statistically significant difference was observed when combining HE4 and CA72.4, but not CA125 and CA 72.4 (p?<?0.002). In conclusion, our study demonstrates that the association of three biomarkers CA125, HE4, and CA72.4 provides a valuable contribution in the follow-up of EOC patients. 相似文献

The purpose of the study was to evaluate the expression of the biomarkers CA125 and HE4 combined with imaging, in patients with advanced epithelial ovarian cancer (EOC). Forty-six women with EOC were included in the study all affected with peritoneal carcinomatosis. Twenty-two of 46 patients (group I) had peritoneal carcinomatosis with small implants in single or in multiple sites (score 1); 24/46 patients (group II) had macro-nodular implants and omental thickening (score 2). High levels of CA125 (350?±?11, mean?±?SEM) have been observed in 21/22 patients of group I, and a similar value (370?±?13) has been observed in all patients belonging to group II. HE4 positivity values (350?±?9) have been observed in all group I patients, whereas all patients belonging to group II showed a higher value of HE4 (600 ± 12). Statistically significant differences were observed between the HE4 levels observed in group I patients in comparison with group II patients (p < 0.0001). In addition, we expressed the extension of lymph nodal disease in three scores: L1-L2-L3, and a statistically significant correlation was observed between high HE4 levels and severity of lymph nodal disease L3 (p < 0.0001). The availability of biomarkers, particularly HE4, together with sophisticated imaging techniques, strengthens the clinical relevance of this study, for the follow-up of patients with peritoneal carcinomatosis. 相似文献
