CHEMOTHERAPEUTIC TREATMENTS INVOLVING DRUG-RESISTANCE AND LEVEL OF NORMAL-CELLS AS A CRITERION OF TOXICITY
(Elsevier Science Publ Co IncNew York, 1995)
EGFR amplification and expression in oral squamous cell carcinoma in young adults
The aim of this study was to investigate epidermal growth factor receptor (EGFR) gene alterations in two groups of patients with oral squamous cell carcinoma (OSCC) (a test group of subjects aged ≤40 years and a control ...
Expresión y amplificación del gen HER2 en el cáncer gástrico avanzado
(Sociedad Médica de Santiago, 2013)
Background: Overexpression/amplification of the HER2 gene in advanced gastric cancer is a predictor of response to adjuvant therapy with monoclonal antibodies. Aim: To determine the frequency of HER2 gene overexpression ...
Araçatuba virus: A vaccinialike virus associated with infection in humans and cattle
We describe a vaccinialike virus, Araçatuba virus, associated with a cowpoxlike outbreak in a dairy herd and a related case of human infection. Diagnosis was based on virus growth characteristics, electron microscopy, and ...
Evaluation of Quantitative RT-PCR Using Nonamplified and Amplified RNA
(LIPPINCOTT WILLIAMS & WILKINS, 2010)
Quantitative reverse-transcription polymerase chain reaction (qRT-PCR) is a standard assay in molecular medicine for gene expression analysis. Samples from incisional/needle biopsies, laser-microdissected tumor cells and ...
Mutation and genomic amplification of the PIK3CA proto-oncogene in pituitary adenomas
(Associação Brasileira de Divulgação Científica, 2012)
The tumorigenesis of pituitary adenomas is poorly understood. Mutations of the PIK3CA proto-oncogene, which encodes the p110-α catalytic subunit of PI3K, have been reported in various types of human cancers regarding ...
Gene expression analysis reveals novel altered genes in nasal polyps
(Spandidos Publ Ltd, 2014)
Indirect immune detection of ecdysone receptor (EcR) during the formation of DNA puffs in Bradysia hygida (Diptera, Sciaridae)
Gene amplification occurs in Bradysia hygida salivary glands, at the end of the fourth larval instar. The hormone 20-hydroxyecdysone (20E) triggers this process, which results in DNA puff formation. Amplified genes are ...
