Hepatomas were induced in rats by feeding N-nitrosomorpholine. Nodules from alpha1-fetoprotein (AFP)-producing hepatoma were taken and subcutaneously injected into syngeneic hosts. From the first generation, the hepatoma producing most AFP was selected for further transfers. Four weeks after transplantation, the AFP concentration in the host rats was in the range of 0.8 to 1.5 mg AFP/ml serum. ...
Alpha-fetoprotein (AFP) represents a classical model system to study developmental gene regulation in mammalian cells. We previously reported that liver ZBTB20 is developmentally regulated and plays a central role in AFP postnatal repression. Here we show that ZBTB20 is a sequence-specific transcriptional repressor of AFP. By ELISA-based DNA-protein binding assay and conventional gel shift assa...
Although alpha-fetoprotein (AFP) is the most widely used biomarker in hepatocellular carcinoma (HCC) surveillance, disease activity may also increase AFP levels in chronic hepatitis B (CHB). Since nucleos(t)ide analog (NA) therapy may reduce not only HBV viral loads and transaminase levels but also the falsely elevated AFP levels in CHB, we tried to determine whether exposure to NA therapy infl...
Levels of alpha-fetoprotein (AFP), its glycoforms AFP-L3 and AFP-P4, and proteins induced by vitamin K absence or antagonist-II (PIVKA-II) were determined in sera obtained from patients in Yangon General Hospital (20 with hepatocellular carcinoma (HCC), 29 with chronic liver diseases, including 3 with chronic hepatitis and 26 with cirrhosis of the liver, and 9 with other hepatobiliary diseases)...
the gene encoding alpha fetoprotein (locus symbol afp) was assigned to rat chromosome 14 at band p21-p22 using fluorescence in situ hybridization method. the present result suggests that there is a conserved syntenic group between human 4q11-q13, mouse 5f-g, and rat 14p21-p22.
We found six bacteria capable of producing antifreeze protein (AFP) from Ross Island, Antarctica. Among these AFP-producing bacteria, strain No. 82 had the highest antifreeze activity and was identified as Moraxella sp. The optimum temperature and pH for the production of AFP were 5 degrees C and 7.0, respectively. After partially purifying the AFP from the culture supernatant using 60% saturat...
AIM To investigate the ability of recombinant modified vaccinia virus Ankara (rMVA) vector to induce an immune response against a well-tolerated self-antigen. METHODS rMVA vectors expressing different form of α-fetoprotein (AFP) were produced and characterized. Naïve mice were vaccinated with MVA vectors expressing the AFP antigen in either a secreted, or a membrane-bound, or an intracellular...
Human alpha-fetoprotein (AFP) was one of the first biomarkers developed as a cancer biomarker and is still today considered the “gold standard” biomarker for liver cancer. AFP is a glycopolypeptide exhibiting a molecular mass of 69 kD with a 3-5% carbohydrate content [1]. Structurally, the full-length AFP molecule consists of three domains forming nine layers of peptide loops configured by 15 c...
Alpha-fetoprotein (AFP) is a common tumor marker for hepatocellular carcinoma (HCC). We report a unique case of an AFP-producing gastric cancer in an elderly man with known chronic hepatitis B (HBV) and a markedly elevated AFP. Thorough diagnostic imaging failed to reveal a HCC, but a gastric adenocarcinoma was found on endoscopy. After successful resection, the serum AFP normalized. On histopa...
We developed a new kit for detecting alpha-fetoprotein (AFP) in leaked amniotic fluid (Eur J Obstet Gynecol Reprod Biol 1995;58:67-72). Later, we developed an improved AFP kit utilizing the same AFP monoclonal antibody. We compared this improved AFP test with the nitrazine test for 137 patients. The nitrazine test correctly diagnosed 62.1% of the cases, but the improved AFP kit diagnosed 98.0% ...
