mrtl-A translation/localization regulatory protein encoded within the human c-myc locus and distributed throughout the endoplasmic and nucleoplasmic reticular network.

mrtl (myc-related translation/localization regulatory factor) is a previously uncharacterized protein synthesized from the first open reading frame contained within the human c-myc P0 transcript, approximately 800 nucleotides upstream of the Myc coding sequence. The mrtl protein, 114 amino acids in length, is projected to contain an N-terminal transmembrane domain and a highly charged C-terminal interaction domain with homology to numerous RNA-binding proteins. Using monoclonal antibodies raised against the hydrophilic C-terminal domain, endogenous mrtl was visualized in human breast tumor cell lines and primary mammary epithelial cells at the nuclear envelope and contiguous endoplasmic/nucleoplasmic reticulum.

Genomic stability of self-complementary adeno-associated virus 2 during early stages of transduction in mouse muscle in vivo.

Studies have demonstrated that packaging of recombinant adeno-associated virus 2 (rAAV) as self-complementary duplex strand (sc) results in early transgene expression, possibly eliminating rate-limiting second-strand synthesis. In the present study, we evaluated the molecular organization, stability of the sc AAV genome, and transgene expression in the quadriceps muscle of C57BL/6J mice in vivo as compared with single-stranded (ss) AAV. Studies were carried out with rAAV encoding green fluorescent protein (GFP) or human carcinoembryonic antigen (CEA) either as single-stranded or self-complementary duplex strand structures, encapsidated in AAV-2 capsids.

DNA vaccines for cancer.

DNA vaccines, also referred to as genetic, plasmid or polynucleotide vaccines, represent a relatively simple and economical method to exploit gene transfer for immunization against tumor associated antigens. This review discusses the potential advantages of DNA vaccines for cancer immunotherapy as compared to conventional protein vaccines and viral vectors. The proposed mechanisms responsible for induction of immune responses following DNA-based immunization are summarized.

A DNA vaccine encoding genetic fusions of carcinoembryonic antigen (CEA) and granulocyte/macrophage colony-stimulating factor (GM-CSF).

The anti-tumor immunologic effects of plasmid DNA vaccines encoding human carcinoembryonic antigen (CEA) fused to mouse granulocyte/macrophage colony-stimulating factor (GM-CSF) were examined. Immunization of C57BL/6 mice with the CEA-GMCSF fusion plasmids in a three injection, high-dose immunization schedule led to T cell and antibody responses specific for CEA. Mice injected with CEA-GMCSF fusion plasmids also developed IgG autoantibodies to GM-CSF.

Antitumor activity of the intratumoral injection of fowlpox vectors expressing a triad of costimulatory molecules and granulocyte/macrophage colony stimulating factor in mesothelioma.

Deficiency in costimulatory molecule expression has been implicated in the ability of tumors to escape immune effectors. The activity of the intratumoral administration of recombinant fowlpox vectors expressing a triad of costimulatory molecules (rF-TRICOM) was evaluated in the asbestos-induced AB12 and AC29 mouse models of mesothelioma. Mesothelioma cell infected with rF-TRICOM expressed high levels of the costimulatory molecules.

Augmentation of antitumor activity of a recombinant adeno-associated virus carcinoembryonic antigen vaccine with plasmid adjuvant.

Recombinant adeno-associated virus 2 (rAAV) vectors have been successfully used for sustained expression of therapeutic genes. The potential of using rAAV as a cancer vaccine vector and the impact of a bacterial plasmid adjuvant on this activity were investigated. C57BL/6 mice received a single intramuscular injection of rAAV expressing the human tumor-associated antigen, carcinoembryonic antigen (CEA).

Evaluation of a selectively oncolytic adenovirus for local and systemic treatment of cervical cancer.

Treatment options for disseminated cervical cancer remain inadequate. Here, we investigated a strategy featuring Ad5-Delta 24 RGD, an oncolytic adenovirus replication-competent selectively in cells defective in the Rb-p16 pathway, such as most cervical cancer cells. The viral fiber contains an alpha(v)beta(3) and alpha(v)beta(5) integrin-binding RGD-4C motif, allowing coxsackie-adenovirus receptor-independent infection.

Characterization of human mesothelin transcripts in ovarian and pancreatic cancer.

Background: Mesothelin is an attractive target for cancer immunotherapy due to its restricted expression in normal tissues and high level expression in several tumor types including ovarian and pancreatic adenocarcinomas. Three mesothelin transcript variants have been reported, but their relative expression in normal tissues and tumors has been poorly characterized. The goal of the present study was to clarify which mesothelin transcript variants are commonly expressed in human tumors.

Adeno-associated virus 2-mediated antiangiogenic cancer gene therapy: long-term efficacy of a vector encoding angiostatin and endostatin over vectors encoding a single factor.

Angiogenesis is characteristic of solid tumor growth and a surrogate marker for metastasis in many human cancers. Inhibition of tumor angiogenesis using antiangiogenic drugs and gene transfer approaches has suggested the potential of this form of therapy in controlling tumor growth. However, for long-term tumor-free survival by antiangiogenic therapy, the factors controlling tumor neovasculature need to be systemically maintained at stable therapeutic levels.

Immunization of colorectal cancer patients with recombinant baculovirus-derived KSA (Ep-CAM) formulated with monophosphoryl lipid A in liposomal emulsion, with and without granulocyte-macrophage colony-stimulating factor.

KSA (Ep-CAM) is highly expressed by colorectal cancers. The safety and immunologic effects of a vaccine consisting of recombinant baculovirus-derived KSA formulated with monophosphoryl lipid A (MPL) in liposomes and emulsified in mineral oil were evaluated, with and without co-administration of granulocyte-macrophage colony-stimulating factor (GM-CSF). Eleven patients with metastatic colorectal cancer received three subcutaneous (s.

Expression of sperm protein 17 (Sp17) in ovarian cancer.

Sperm protein 17 (Sp17) is an antigenic protein highly expressed in spermatozoa. Sp17 expression was demonstrated recently in multiple myeloma, suggesting that it may be a novel cancer-testis antigen. Expression of Sp17 mRNA and protein was examined in human ovarian tumors.

Codon usage optimization of HIV type 1 subtype C gag, pol, env, and nef genes: in vitro expression and immune responses in DNA-vaccinated mice.

Codon usage optimization of human immunodeficiency virus type 1 (HIV-1) structural genes has been shown to increase protein expression in vitro as well as in the context of DNA vaccines in vivo; however, all optimized genes reported thus far are derived from HIV-1 (group M) subtype B viruses. Here, we report the generation and biological characterization of codon usage-optimized gag, pol, env (gp160, gp140, gp120), and nef genes from a primary (nonrecombinant) HIV-1 subtype C isolate. After transfection into 293T cells, optimized subtype C genes expressed one to two orders of magnitude more protein (as determined by immunoblot densitometry) than the corresponding wild-type constructs.

Safety and immunogenicity of a DNA vaccine encoding carcinoembryonic antigen and hepatitis B surface antigen in colorectal carcinoma patients.

Despite an abundance of preclinical data, relatively little is known regarding the efficacy of DNA vaccination in humans. Here, we present results from a dose-escalation clinical trial of a dual expression plasmid encoding carcinoembryonic antigen (CEA) and hepatitis B surface antigen (HBsAg) in 17 patients with metastatic colorectal carcinoma. CEA was selected as a prototypic tumor-associated self-antigen, and the HBsAg cDNA was included as a positive control for immune response to the DNA vaccine without relying upon breaking tolerance to a self-antigen.
