Betulinic acid (BA) is a widely available plant-derived triterpene with reported activity against cancer cells of neuroectodermal origin and leukaemias. Treatment with BA was shown to protect mice against transplanted human melanoma and led to tumor regression. In contrast, cells from healthy tissues were resistant to BA and toxic side-effects in animals were absent. These findings have raised interest...
Glucose transporters (Gluts) facilitate glucose uptake and tumors frequently over express the Gluts, especially Glut-1. Breast cancer and lung cancer (NSCLC) cell lines were incubated with anti-Glut-1 antibodies alone or with cisplatin, paclitaxel or gefitinib. Inhibition of proliferation and apoptosis was assessed. Antibodies to Glut-1 inhibited proliferation by 50% and 75% in the tested NSCLC and...
