Abstract:
Mutations in LMNA encoding lamins A and C are associated with at least 10 different degenerative disorders affecting diverse tissues, collectively called laminopathies. A recent study showed that mis-accumulation of SUN1 underlies the pathology of degenerative features in laminopathies, and concomitantly suggests a gain-of-function versus a loss-of-function model for the action of lamin A mutants.

Loss of Tumor Suppressor Gene Functions
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

The Retinoblastoma Gene
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
