The late embryogenesis-abundant (Lea) genes, which are suggested to act as desiccation protectants during seed desiccation and in water-stressed seedlings, can be induced by abscisic acid (ABA) and various kinds of water-related stress. Using cotton Lea cDNAs as probes it was found that several of the Lea genes are conserved at the mRNA level in dicots and(More)
Minutes comprise > 50 phenotypically similar mutations scattered throughout the genome of Drosophila, many of which are identified as mutations in ribosomal protein (rp) genes. Common traits of the Minute phenotype are short and thin bristles, slow development, and recessive lethality. By mobilizing a P element inserted in the 5' UTR of M(3)95A, the gene(More)
Dendritic cells (DCs) are being explored as a therapeutic vaccine for cancers. However, their immunogenic potential is limited by the presence of immunosuppressive factors. Among these factors is the tryptophan-degrading enzyme indoleamine 2,3-dioxygenase (IDO). In this study, we have investigated the safety, immunogenicity and clinical response of(More)
Minutes comprise > 50 phenotypically similar Drosophila mutations believed to affect ribosomal protein genes. Common traits of the Minute phenotype are short and thin bristles, slow development, and recessive lethality. To further investigate the proposed Minute to ribosomal protein correspondence, loss-of-function Minute mutations were induced by P-element(More)
Minutes (M) are a group of over 50 phenotypically similar Drosophila mutations widely believed to affect ribosomal protein genes. This report describes the characterization of the P element-induced M(3)95A(Plac92) mutation [allelic to M(3)95A]. This mutation can be reversed by the mobilization of the P element, demonstrating that the mutation is caused by(More)
Most cancer vaccines to date have made use of common tumor antigens or allogenic cancer cell lines. The majority of tumor antigens may, however, be unique patient-specific antigens. Dendritic cells (DCs) are the most potent antigen-presenting cells known. The present report is a full-scale preclinical evaluation of autologous DCs transfected with autologous(More)
Dendritic cells (DCs) are recognised as the most potent antigen-presenting cells for induction of cellular immune responses, and vaccination with DCs pulsed with antigens has emerged as a promising strategy for generating protective immunity in mammals. We have developed a transfection method that uses in vitro synthesised mRNA and square-wave(More)
The exploration of messenger RNA (mRNA) as a potential therapeutic regulator of gene expression has been significantly reduced by the inability of polyplexes to escape the endocytic pathway, combined with the lack of specific targeting. In the present study, we have developed a site-specific delivery strategy for mRNA molecules through the use of(More)
Among the many promising cancer immunotherapeutic strategies, dendritic cells (DC) have become of particular interest. This study aims to optimize a clinical grade protocol for culture and transfection of human DC. Monocytes and CD34(+) hematopoietic stem cells (HSC) from same donor were differentiated under serum-free conditions and analyzed for their(More)
Children with high-risk neuroblastoma (NB) have a poor clinical outcome. The purpose of the present study was to evaluate different strategies for immunotherapy of high-risk NB based on vaccination with antigen-loaded dendritic cells (DCs). DCs are professional antigen-presenting cells with the ability to induce antitumor T-cell responses. We have compared(More)
