[This retracts the article on p. 2019 in vol. 7, PMID: 28111587.].
The cytoskeleton is a dynamic scaffold in living cells even in the absence of externally imposed forces. In this study on cytoskeletal deformation, the applicability of hierarchical feature vector matching (HFVM), a new matching method, currently applied in space research and three-dimensional surface reconstruction, was investigated. Stably transfected CHO-K1 cells expressing green fluorescent...
Drosophila Using Gal4-UAS-Driven Expression of GFP Fused to the Actin-Binding Domain of Moesin Devkanya Dutta, James W. Bloor, Mar Ruiz-Gomez, K. VijayRaghavan, and Daniel P. Kiehart* National Centre For Biological Sciences, UAS Campus, Bangalore, India Developmental, Cell and Molecular Biology Group, Department of Biology, Duke University, Durham, North Carolina, USA Research School of Bioscie...
The introduction of several mutations resulted in the generation of improved mutants of the green fluorescent protein (GFP). A strong green (GFPsg25) and blue (BFPsg50) fluorescent protein, gave 50-fold-100-fold brighter fluorescence compared to wild-type GFP and BFP (Tyr66His), respectively, upon expression in mammalian cells. GFPsg25 and BFPsg50 have different excitation and emission maxima. ...
We have applied Raster Image Correlation Spectroscopy (RICS) technique to characterize the dynamics of protein 53 (p53) in living cells before and after the treatment with DNA damaging agents. HeLa cells expressing Green Fluorescent Protein (GFP) tagged p53 were incubated with and without DNA damaging agents, cisplatin or eptoposide, which are widely used as chemotherapeutic drugs. Then, the di...
The ability to chronically monitor neuronal activity in the living brain is essential for understanding the organization and function of the nervous system. The genetically encoded green fluorescent protein-based calcium sensor GCaMP provides a powerful tool for detecting calcium transients in neuronal somata, processes, and synapses that are triggered by neuronal activities. Here we report the...
Transformed rat fibroblasts expressing two variants of green fluorescent protein, each fused to beta-actin, were used to study actin dynamics during cell protrusion. The recently developed FLAP (fluorescence localization after photobleaching) method permits the tracking of one fluorophore after localized photobleaching by using the other as a colocalized reference. Here, by visualizing the rati...
Although numerous techniques have been developed to monitor autophagy and to probe its cellular functions, these methods cannot evaluate in sufficient detail the autophagy process, and suffer limitations from complex experimental setups and/or systematic errors. Here we developed a method to image, contextually, the number and pH of autophagic intermediates by using the probe mRFP-GFP-LC3B as a...
