The blocking of the oncogenic pathways in different malignancies can contribute to molecularly targeted therapeutics and has clinical benefits. c-Src is arguably the oldest known oncogene and most important proto-oncogen in the development and progression of colon cancer. It is often over-expressed and activated in the number of human cancers such as colon, prostate, brain, lung, breast, ovaria...

the p63 gene, a member of the p53 gene family, is expressed into at least six protein isoforms.the transcription factor p63 is a homologue of the tumor suppressor p53. unlike p53, which is dispensable for normal development, p63 is critical for the development of stratified epithelial tissues such as epidermis, breast, and prostate. p63, , is transcribed from two different promoters giving rise...

Injection s.c. of purine 3-oxide into Wistar rats resulted in the appearance of sarcomas and fibromas at the interscapular site of administration, carcinomas in the liver, and a high incidence of s.c. fibromas in the hip at a distance from the site of injection. A small number of liver tumors but no tumors at the injection site appeared in rats to which the parent compound, purine, was administ...

Monocytes from patients with sepsis have a reduced capacity to produce cytokines, a state referred to as immunoparalysis. To determine whether polymorphonuclear leukocytes (PMNL) can be rendered hyporesponsive, PMNL from 6 healthy volunteers intravenously challenged with lipopolysaccharide (LPS; 4 ng/kg) were stimulated ex vivo with heat-killed bacteria or LPS, and the release of the CXC chemok...

The 9E10 antibody epitope (EQKLISEEDL) derives from a protein sequence in the human proto-oncogen p62(c-myc) and is widely used as a protein fusion tag. This myc-tag is a powerful tool in protein localization, immunochemistry, ELISA or protein purification. Here, we characterize the myc-tag epitope by substitutional analysis and length variation using peptide spot synthesis on cellulose. The ke...

The study searched for epidermal growth factor receptor (EGFR) gene amplification in hyperplastic glottis lesions. After classical pathohistological findings of hematoxylin-eosin (HE) slides and quantitative immunohistochemical (IHC) analysis, fluorescent in situ hybridization (FISH) was used on tissue microarrays of laryngeal hyperplastic tissue ranging from normal mucosa to abnormal and atypi...
