Cancer vaccine regimens use various strategies to enhance immune responses to specific tumor-associated antigens (TAAs), including the increasing use of recombinant poxviruses [vaccinia (rV) and fowlpox (rF)] for delivery of the TAA to the immune system. However, the use of replication competent vectors with the potential of adverse reactions have made attenuation a priority for next-generation...
PURPOSE The poor immunogenicity of tumor antigens and the antigenic heterogeneity of tumors call for vaccine strategies to enhance T-cell responses to multiple antigens. Two antigens expressed noncoordinately on most human carcinomas are carcinoembryonic antigen (CEA) and MUC-1. We report here the construction and characterization of two viral vector vaccines to address these issues. EXPERIME...
Carcinoembryonic antigen messenger RNA expression in blood predicts recurrence in esophageal cancer.
PURPOSE The clinical significance of isolated tumor cells (ITC) in blood has not been clearly established, particularly during follow-up in cancer patients. We conducted a longitudinal analysis of the relationship between ITC in blood during follow-up and clinicopathologic findings in patients with esophageal squamous cell carcinoma. EXPERIMENTAL DESIGN Blood samples obtained from 106 patient...
The content of carcinoembryonic antigen (CEA) and its subcellular distribution were studied in nine human colon carcinoma cell lines. A great variation in CEA content was found among different colon cancer cell lines. Well-differentiated colon cancer cell lines (LS174T and SKCO-1) contained the highest CEA activity which was 35 to 60 times greater than that of less welldifferentiated cells (SW6...
Introduction: Previous studies shows L-arginin (nitric oxide precursor) increases conditioned place preference and drug seeking behaviors whereas LG-nitro-arginine methyl ester) L-NAME( as nitric oxide synthase inhibitor decreases this process. In this project, effects of intra-central amygdale bilateral injection of nitric oxide agents on drug-seeking behaviors including rearing, sniffing and ...
Background and Aim: Lung cancer is the most common cancer among men around the world. The aim of this study was to determine the expression levels of CK19 mRNA marker in the affected patients’ peripheral blood. Materials and Methods: Thirty patients with lung cancer (NSCLC type) were compared with 30 healthy controls. After taking peripheral blood samples and extracting total RNA, cDNA was s...
Carotid artery plaques are a leading cause of ischemic stroke, and carotid endarterectomy (CEA) is one of the major treatment approaches for this disease. Changes in cerebral metabolism following CEA remain unclear. The present study aimed to evaluate the effect of cerebral ammonia metabolism following CEA using 13N‑labeled ammonia positron emission tomography (PET) in humans. A total of 20 pat...
Internal image anti-idiotypic antibodies are capable of mimicking tumor-associated antigens and thus may serve as surrogate for vaccination strategies in cancer patients. The monoclonal antibody (mAb) 6G6.C4 mimics an epitope specific for the human carcinoembryonic antigen (CEA) and generates a CEA-specific response (Ab3) in various experimental animals. In humans, however, 6G6.C4 only yields a...
Abstract Memory formation is key for brain functioning. Uncovering the memory mechanisms helping us to better understand neural processes in health and disease. Moreover, more specific treatments fear-related disorders such as posttraumatic stress disorder phobias may help decrease their negative impact on mental health. In this line, Tachykinin 2 (Tac2) pathway central amygdala (CeA) has been ...
