The role of inositol 1,4,5-trisphosphate (IP(3)) in transducing heat-shock (HS) signals was examined in Arabidopsis. The whole-plant IP(3) level increased within 1 min of HS at 37 degrees C. After 3 min of HS, the IP(3) level reached a maximum 2.5 fold increase. Using the transgenic Arabidopsis plants that have AtHsp18.2 promoter-beta-glucuronidase (GUS)(More)
To establish objectively the involvement of neurons in the medulla oblongata in patients with amyotrophic lateral sclerosis (ALS), ribonucleic acid (RNA) content was determined in neurons of the hypoglossal nucleus and the nucleus ambiguus. Neurons from those two nuclei showed a significant loss of RNA content in patients with ALS; only 57% and 38% of the(More)
Developing brine shrimp are a good experimental model for study of gene expression during development. Development is initiated on suspension of brine shrimp cysts in seawater. Only 48 hr are required for progression from cyst to the larval stage. We have localize the alpha- and beta-subunits in different cells by immunostaining as development progresses.(More)
ECBP21 is a calmodulin binding protein (CaMBP) purified from extracellular extracts of suspension-cultured cells of Angelica dahurica, and it is the first reported extracellular CaMBP in plant kingdom. We have recently cloned the full-length cDNA for ECBP21. In this work, using recombinant ECBP21 we prepared rabbit antiserum with high specificity and high(More)
An antisense oligonucleotide (54 mer) from the mRNA to the midsize neurofilament protein (NFM) was labeled with 35S on the 3' end and purified by polyacrylamide gel electrophoresis (PAGE). In situ hybridization was performed on sections from medulla oblongata of patients with amyotrophic lateral sclerosis (ALS). The slides were dipped in photographic(More)
Extradomain-B fibronectin (EDB-FN), one of the oncofetal fibronectin (onfFN) isoforms, is a high-molecular-weight glycoprotein that mediates cell adhesion and migration. The expression of EDB-FN is associated with a number of cancer-related biological processes such as tumorigenesis, angiogenesis, and epithelial-to-mesenchymal transition (EMT). Here, we(More)
Development of a gene delivery system with high efficiency and a good safety profile is essential for successful gene therapy. Here we developed a targeted non-viral delivery system using a multifunctional lipid ECO for treating Leber's congenital amaurosis type 2 (LCA2) and tested this in a mouse model. ECO formed stable nanoparticles with plasmid DNA(More)
We used in situ hybridization histochemistry with synthetic oligonucleotide probes to localize the mRNAs encoding the alpha 2- and beta-mRNAs of Na,K-ATPase during development of the brine shrimp Artemia. The mRNAs of the alpha 2- and beta-subunit were of low abundance in the cysts; in addition, less mRNA of the beta-subunit was localized. During emergence(More)
Biocompatible dendrimers with well-defined nanosizes are increasingly being used as carriers for drug delivery. 5-Aminosalicylic acid (5-ASA) is an FDA-approved therapeutic agent recently found effective in treating retinal degeneration of animal models. Here, a water-soluble dendrimer conjugate of 5-ASA (AGFB-ASA) was designed to treat such retinal(More)
