No investigation to data was undertaken on SIRPalphal involving liver regeneration. MATERIALS AND METHODS: Adult male Sprague-Dawley rats underwent approximately 700% partial hepatectomy (PH) or sham operation (SO). Liver specimens were collected at 2，6，12，24，30，48，72，120，168,and 240 h after PH or SO.展开更多

No additional mutation of c-src exon 12 was found.CONCLUSION: c-src codon 531 mutation in colorectal cancer is not the cause of c-src activation.展开更多
