Chimeric ferritin as a reporter for MRI
Introduction The iron storage protein ferritin is a heteropolymer composed of H and L subunits (1). The H subunit contains a ferroxidase site, whereas the L chain provides the nucleation centers for deposition of the ferrihydrite core (1). The subunit ratio H:L varies across different tissues and cell types (2). Recent reports used the paramagnetic ferritin core as a probeless MRI reporter (3, ...
متن کاملlacZ transgenic rats tolerant for beta-galactosidase: recipients for gene transfer studies using lacZ as a reporter gene.
Gene transfer of reporter genes may trigger immune responses against the heterologous protein resulting in shortening of gene expression and inflammation. We generated transgenic rats expressing the lacZ gene under the control of the human immunodeficiency virus type 1 (HIV-1) long-terminal repeat (LTR) (HIV-lacZ) to obtain rats with undetectable transgene expression using histologic methods, t...
متن کاملDevelopment of Timd2 as a reporter gene for MRI
PURPOSE To assess the potential of an MRI gene reporter based on the ferritin receptor Timd2 (T-cell immunoglobulin and mucin domain containing protein 2), using T1- and T2-weighted imaging. METHODS Pellets of cells that had been modified to express the Timd2 transgene, and incubated with either iron-loaded or manganese-loaded ferritin, were imaged using T1- and T2-weighted MRI. Mice were als...
متن کاملDevelopment of Streptococcus thermophilus lacZ as a reporter gene for Candida albicans.
The study of gene regulation in many organisms has been facilitated by the development of reporter genes. The authors report the use of lacZ from Streptococcus thermophilus, a gene encoding a beta-galactosidase, as a reporter for the fungal pathogen Candida albicans. As test cases, Strep. thermophilus lacZ was placed under control of three different C. albicans promoters: MAL2 (maltase), induci...
متن کاملlacZ reporter system for use in Borrelia burgdorferi.
Regulation of gene expression is critical for the ability of Borrelia burgdorferi to adapt to different environments during its natural infectious cycle. Reporter genes have been used successfully to study gene regulation in multiple organisms. We have introduced a lacZ gene into B. burgdorferi, and we show that B. burgdorferi produces a protein with detectable β-galactosidase activity in both ...
