The inhibition of cancer growth and progression is one of the major challenges facing modern medicine. Despite significant progress in the development of therapies against cancer, only in a few cases are these therapies effective. Because cancer is a complex disease, agents that target a single oncogenic pathway have low efficacy, in addition to allowing(More)
Long double-stranded RNA (>30 bp), usually expressed in cells infected with RNA viruses, triggers antiviral responses that induce apoptosis of the infected cells. PKR can be selectively activated in glioblastoma cells by in situ generation of dsRNA following introduction of antisense RNA complementary to an RNA expressed specifically in these cells.(More)
Over the past decade progress has been made in the development of therapies against cancer. Small molecules, mainly tyrosine kinase inhibitors (tyrphostins) like Gleevec, Iressa targeting CML and EGFR overexpressing tumors have entered the clinic, where a large number of other tyrphostins are at various stages of clinical development. In parallel a few(More)
Activated double-stranded RNA (dsRNA)-dependent protein kinase PKR is a potent growth inhibitory protein that is primarily activated in virally infected cells, inducing them to die. We have recently shown that PKR can be selectively activated in cancer cells, by in situ generation of dsRNA following introduction of antisense RNA complementary to an RNA(More)
We prospectively studied five patients with a remote history of Streptococcus bovis bacteremia who had not previously been evaluated for colonic pathology. This study was prompted by several reports of concomitant neoplasia in patients with recent S. bovis bacteremia. The patients were studied at a mean of 32 months after bacteremia. Despite the absence of(More)
We report a case of necrotizing amebic colitis with the sigmoidoscopic finding of a confluent, grayish pseudomembrane. The patient was referred from a chronic mental institution, which represents the patient population most susceptible to fulminant amebic dysentery in the United States. The pseudomembrane was a reflection of extensive mucosal necrosis and(More)
