Laser microbeam abalation of GFP-labeled nuclear organelles in a living cell.
Abstract
Cancer, development, cellular growth and differentiation are governed by gene expression. Recent molecular and cellular advances to visualize and perturb the pathways of transcriptional regulation, nascent RNA processing, and protein trafficking at the single cell level have been developed. More recently, applications utilizing the green fluorescent marker (GFP) from Aequorea victoria have facilitated visualization of these molecular events in a living cell. Specifically, we will describe a novel approach to perturb cellular processes by labeling discrete cellular components of interest with GFP and subsequently altering/ablating them with a laser microbeam. ©2004 Copyright SPIE - The International Society for Optical Engineering.
