ABSTRACT Botrytis blight (gray mold), caused by Botrytis cinerea, is one of the most widely distributed diseases of ornamental plants. In geranium plants, gray mold is responsible for important losses in production. The mold Aspergillus giganteus is known to produce and secrete a basic low-molecular-weight protein, the antifungal protein (AFP). Here, the antifungal properties of the Aspergillus...

The mould Aspergillus giganteus produces a basic, low molecular weight protein (AFP) showing in vitro and in vivo antifungal properties against important plant pathogens. AFP is secreted as an inactive precursor containing an amino-terminal extension of six amino acids (lf-AFP) which is later removed to produce the active protein. The molecular basis to explain this behavior and the features th...

α-Fetoprotein (AFP) is known to be highly produced in fetal liver despite its barely detectable level in normal adult liver. On the other hand, hepatocellular carcinoma often shows high expression of AFP. Thus, AFP seems to be an oncogenic marker. In our present study, we investigated how TGF-β signaling cooperates with AT motif-binding factor-1 (ATBF1) to inhibit AFP transcription. Indeed, the...

PURPOSE An existing immunological paradigm is that high concentrations of soluble protein contribute to the maintenance of peripheral tolerance/ignorance to self protein. We tested this hypothesis in a clinical immunotherapy trial using class I-restricted peptide epitopes derived from alpha-fetoprotein (AFP). AFP is a self protein expressed by fetal liver at high levels, but transcriptionally r...

Parity in women is associated with reduced lifetime risk of breast cancer, and hormones of pregnancy [estrogen (E), progesterone (P), human chorionic gonadotropin (hCG)] are implicated. Parity also reduces mammary cancer risk in carcinogen-exposed rats, and administering pregnancy hormones to these animals is similarly effective. Because pregnancy hormones are also able to stimulate cancer grow...

Hepatocellular carcinoma (HCC) is a big problem in China where the Hepatitis B (HBV) infection patients are near to 120 million. Early screening and diagnosis is the key to reduce the incidence and mortality of HCC. Serum AFP detection is the main methods for diagnosis, recurrent monitoring and therapeutic evaluation of primary HCC. Hepatitis patients should detect the AFP at least once every s...

Detection and investigation of all cases of acute flaccid paralysis (AFP) in children below 15 years of age are among the criteria for poliomyelitis-free certification. In the absence of poliomyelitis the incidence of AFP is around 1 per 100,000 children aged < 15 years. In the Netherlands, surveillance of AFP began in October 1992 under the supervision of the Dutch Paediatric Surveillance Syst...

A novel electrochemical immunosensor for tumor biomarker detection based on three-dimensional, magnetic and electroactive nanoprobes was developed in this study. To fabricate the nanoprobes, negatively charged Fe(3)O(4) nanoparticles (Fe(3)O(4) NPs) and gold nanoparticles (Au NPs) were first loaded on the surface of multiple wall carbon nanotubes (MCNTs) which were functioned with redox-active ...

Serum alpha-fetoprotein (AFP) levels and its expression in liver tissue was studied in 50 cases of histologically confirmed hepatocellular carcinoma (HCC). Serum AFP levels were elevated (greater than 20iu/ml) in 35/50 (70%) of the cases, 28 of whom had levels greater than 500 iu/ml, which is highly suggestive of HCC. These results indicate that serum AFP, by itself, is a relatively insensitive...

We report a case of alpha-fetoprotein (AFP) producing renal cell carcinoma. A 53-year-old man with fever was found to have a left renal mass on computed tomography. No mass was detected in the liver. Serum AFP was 1,460 ng/ml. Radical nephrectomy showed a 10 cm mass in the upper half. A half of the tumor was whitish yellow and firm whereas another half was soft and bright yellow with hemorrhagi...
