Targeting arginine auxotrophy in pancreatic cancer cells using human recombinant arginase I-induced arginine deprivation. (c2017)
منشور في 2017"…This absence of caspase activation was confirmed by a 72 hours cytotoxicity assay on Panc-1 cells, which revealed the failure of the pan-caspase inhibitor, Z-VAD, to reverse or decrease arginine depletion-triggered cell death. These findings indicate that HuArgI (Co)-PEG5000-induced arginine depletion results in nonapoptotic, caspase-independent cell death. …"

Surgical Strategies for Synchronous Colorectal Liver Metastases in 156 Consecutive Patients
منشور في 2015"…Surgical resection of all tumor sites is the only treatment that enables prolonged survival, but the synchronous presentation of CLM has been associated with poor outcomes.1 Preoperative chemotherapy is widely used in these patients to provide early treatment of metastatic disease, to improve patient selection for surgical resection,2 and 3 and to decrease the recurrence rate after surgery.4 The traditional surgical strategy for patients with resectable synchronous CLM includes resection of the primary tumor followed by chemotherapy and then liver resection. …"
