The retinoblastoma paradigm revisited

2008

Background: Retinoblastoma (Rb) is the most common primary malignant intraocular tumour in childhood. The "two hit" theory, formulated by Knudson in 1971 to explain the variegated clinical expression of the disease, led to the discovery of the so called tumour suppressor genes and the identification of the Rb1 as the prototype of such genes. Mutations of the Rb1 gene are now commonly believed to be the "cause" retinoblastoma, although epidemiological, clinical, and biological evidences argue against it. Material/Methods: The Authors have performed a systematic review of available data concerning clinical and diagnostic aspects of retinoblastoma, including molecular genetics. Meta analysis o…

Optimization of a new lead promoting the readthrough of the nonsense mutations for CFTR rescue in human CF cells Laura Lentini, Raffaella Melfi, Sara Baldassano, Marco Tutone, Aldo Di Leonardo, Andrea Pace, Ivana Pibiri Department of Biological, Chemical and Pharmaceutical Sciences and Technologies (STEBICEF), University of Palermo Background and rationale Cystic Fibrosis patients with nonsense mutations in the CFTR gene have a more severe form of the disease. Nonsense mutations represent about 10% of the mutations that affect the CFTR gene and they are frequently associated to the classical F508 mutation (1). A potential treatment for this genetic alteration is to promote the translationa…
