VP-0502AL is predicted to become a new highly bioavailable anti-AIDS drug candidate and/or lead compound. -
Immunohistochemical expression of h-telomerase reverse transcriptase in canine and feline meningiomas
Luciana Mandrioli, Serena Panarese, Alessandro Cesari, Maria Teresa Mandara, Paolo Stefano Marcato, Giuliano Bettini 대한수의학회 Journal of Veterinary Science 5 Pages
대한수의학회 Journal of Veterinary Science 2007, 제 8권 제 2호 2 111-115 (5 pages)
association between h-TERT immunolabelling and sex or histotype was evident in dogs or cats. The telomerase enzyme represents a fundamental parameter of potential malignant transformation, which may occur independently of the signal to proliferate, thereby supplying the cells with unlimited growth capabilities. Telomerase expression could be a prognostic indicator independent of the kinetic parameters, although this should be evaluated using a larger dataset with available clinical information. -
