- The International Cancer Genome Consortium (ICGC) was launched to coordinate large-scale cancer genome studies in tumours from 50 different cancer types and/or subtypes that are of clinical and societal importance across the globe. Systematic studies of more than 25,000 cancer genomes at the genomic, epigenomic and transcriptomic levels will reveal the repertoire of oncogenic mutations, uncover traces of the mutagenic influences, define clinically relevant subtypes for prognosis and therapeutic management, and enable the development of new cancer therapies.

- Recently, there has been growing interest in applying fluorescence imaging techniques to the study of various disease processes and complex biological phenomena in vivo. To apply these methods to clinical settings, several groups have developed protocols for fluorescence imaging using antibodies against tumor markers conjugated to fluorescent substances. Although these probes have been useful in macroscopic imaging, the specificity and sensitivity of these methods must be improved to enable them to detect micro-lesions in the early phases of cancer, resulting in better treatment outcomes. To establish a sensitive and highly specific imaging method, we used a fluorophore-conjugated anti-carcinoembryonic antigen (CEA) antibody to perform macroscopic and microscopic in vivo imaging of inoculated cancer cells expressing GFP with or without CEA. Macroscopic imaging by fluorescence zoom microscopy revealed that bio-conjugation of Alexa Fluor 594 to the anti-CEA antibody allowed visualization of tumor mass consisting of CEA-expressing human cancer cells, but the background levels were unacceptably high. In contrast, microscopic imaging using a two-photon excitation microscope and the same fluorescent antibody resulted in subcellular-resolution imaging that was more specific and sensitive than conventional imaging using a fluorescence zoom microscope. These results suggest that two-photon excitation microscopy in conjunction with fluorophore-conjugated antibodies could be widely adapted to detection of cancer-specific cell-surface molecules, both in cancer research and in clinical applications.

- The present study was designed to determine whether the p53 tumor-suppressor protein is involved in the development of antinociceptive tolerance to morphine. When the doses of morphine (mg/kg per injection) were subcutaneously given into mice as pretreatment twice daily for 2 days (first day (30) and second day (60)), intrathecal (i.t.) administration of morphine (0.1nmol) was inactive due to antinociceptive tolerance in the 0.5% formalin test on the third day. Tolerance to i.t. morphine was significantly suppressed by i.t. injection of pifithrin-alpha (1 and 10nmol), an inhibitor of p53 activation, benzyloxycarbonyl-Val-Ala-Asp(OMe)-fluoromethylketone (Z-VAD-fmk) (1 and 10nmol), a non-selective caspase inhibitor, or N(G)-nitro-l-arginine methyl ester (l-NAME) (2 and 20nmol), a non-selective inhibitor of nitric oxide synthase, 5min before each morphine treatment during the induction, with none given on the test day. Moreover, p53 expression in the spinal cord had increased significantly 14h after the last morphine administration. These results indicate that the increased expression and activation of p53, and the nitric oxide and caspase systems related to p53 may contribute to the development of antinociceptive tolerance to morphine in the mouse spinal cord.
