PURPOSE Saccharomyces cerevisiae, a nonpathogenic yeast, has been used previously as a vehicle to elicit immune responses to foreign antigens, and tumor-associated antigens, and has been shown to reduce tumor burden in mice. Studies were designed to determine if vaccination of human carcinoembryonic antigen (CEA)-transgenic (CEA-Tg) mice (where CEA is a self-antigen) with a recombinant S. cerev...

BACKGROUND Carcinoembryonic antigen (CEA) as a marker in the follow-up after curative resection of colorectal carcinoma (CRC) is often omitted from follow-up despite guideline recommendations. One reason is the assumption that when a normal CEA value exists before curative resection of CRC, it will neither rise during follow-up. This study investigates this relationship. METHOD Data were deri...

Purpose The aim of this study was to evaluate whether the perioperative carcinoembryonic antigen (CEA) ratio could be used as a determinant for adjuvant therapy after curative surgery in stage II colorectal cancer. Methods Data for 119 patients with stage II colorectal cancer who underwent radical surgery between 2010 and 2013 were collected. The perioperative CEA ratio was defined as the pos...

BACKGROUND To investigate serum carcinoembryonic antigen (CEA) as a prognostic factor for rectal cancer patients receiving pre-operative chemoradiotherapy (CRT). METHODS Between 2000 and 2009, 138 patients with advanced rectal cancer receiving CRT before surgery at our hospital were retrospectively classified into 3 groups: pre-CRT CEA <6 ng/ml (group L; n = 87); pre-CRT CEA ≥ 6 ng/ml and pos...

Objective: To evaluate the effect of dialysis and kidney transplantation on serum levels of several tumor markers such as PSA, AFP, CA125, CA19- 9, CA15-3, CEA and to compare with normal age matched controls. Methods: Between September of 2000 and July of 2001, the following tumor markers: PSA, AFP, CA125, CA19-9, CA15-3 and CEA were measured by ELISA Method in 29 hemodialyzed patients (group A...

High-intensity endurance exercise (HIE) induces negative emotions alongside fatigue, suffering, and changes in cardiovascular responses, these regulations could be important for athletic performance. Previous studies have reported that limbic brain stem regions, including the central nucleus of amygdala (CeA), paraventricular hypothalamus (PVH), tractus solitarii (NTS), play roles emotional res...

We have constructed a DNA plasmid encoding the full length complementary DNA for human carcinoembryonic antigen (CEA) driven by the cytomegalovirus early promoter/enhancer (plasmid DNA encoding human CEA) and demonstrated that this plasmid can function as a polynucleotide vaccine. This polynucleotide vaccine induced humoral and/or cellular immune responses specific for human CEA in all 5 immuni...

In vivo, carcinoembryonic antigen (CEA) is removed from the circulation by the liver Kupffer cells. Immunologically identifiable CEA is transferred from these macrophages to the hepatocytes, where degradation is completed. Circulatory clearance of CEA is specific, rapid [t1/2 = 3.7 +/- 0.9 (S.D.) min], and saturable. In vitro, Kupffer cells take up CEA by a saturable process which is time/tempe...
