Acylaminoacyl peptidase from Aeropyrum pernix is a homodimer that belongs to the prolyl oligopeptidase family. The monomer subunit is composed of one hydrolase and one propeller domain. Previous crystal structure determinations revealed that the propeller domain obstructed the access of substrate to the active site of both subunits. Here we investigated the structure and the kinetics of two mut...
BACKGROUND In a retrospective analysis of 195 patients with small cell lung cancer (SCLC), we examined the prognostic value of a coexpression of fragile histidine triad (FHIT) protein and c-kit on patient's survival. METHODS As assessed by immunohistochemistry using formalin-fixed, paraffin-embedded tissue sections, tumors of 195 patients with SCLC were evaluated for FHIT and c-kit coexpressi...
Histidine is an amino acid precursor of neuronal histamine. It is evident that peripheral injection of histidine produces effects that resemble to centrally administered histamine. The aim of the present study was to compare the effects of intracerebroventricular (ICV) injection of histamine and inraperitoneal (IP) injection of histidine on food intake in rabbits. ICV injections of histamine (1...
AIMS Chromosome 3p allele loss is a frequent event in many common sporadic cancers including lung, breast, kidney, ovarian, and head and neck cancer. To analyse the extent and frequency of 3p allelic losses in T1N0 and T1N1 invasive sporadic breast cancer, 19 microsatellite markers spread along 3p were analysed in 40 such breast carcinomas with known clinicopathological parameters. METHODS Lo...
We previously cloned and characterized the tumor suppressor gene FHIT (fragile histidine triad) at chromosome 3p14.2 and found that this gene is altered by deletions in human tumors, including lung cancer. To assess the frequency and specificity of inactivation and its relevance in a clinical setting, we have produced antibodies against the Fhit protein and studied its expression in a series of...
The High-mobility group AT-hook 2 protein (HMGA2) is involved in different processes during tumorigenesis. High expression levels of HMGA2 are found in various types of cancer, with recent studies highlighting the important role of miRNAs in the regulation of HMGA2 expression. We report a study of 155 ovarian tumors (30 sex-cord stromal tumors, 22 borderline tumors, and 103 carcinomas) analyzed...
