Selective gene amplification [PDF]
We describe a system for directed evolution based on in vitro compartmentalisation in which amplification of a gene is coupled to the formation of product by the enzyme it encodes. This approach mimics the process of natural selection; 'fitter' genes--encoding more efficient enzymes--have more 'offspring'.

The prognostic impact of EGFR, ErbB2 and MET gene amplification in human gastric carcinomas as measured by quantitative Real-Time PCR [PDF]
Purpose: Identification of critical genes which play pivotal roles in controlling tumor growth and survival will establish the basis for developing therapeutic targets. In this study, we focused on frequencies of EGFR, ErbB2 and MET gene amplification in

Gene amplification in carcinogenesis
Gene amplification increases the number of genes in a genome and can give rise to karyotype abnormalities called double minutes (DM) and homogeneously staining regions (HSR), both of which have been widely observed in human tumors but are also known to ...

Topoisomerase expression and amplification in solid tumours: Analysis of 24,262 patients. [PDF]
BackgroundTopoisomerase I (TOPO1) and topoisomerase IIα (TOP2A) are specific targets of multiple chemotherapy drugs. Increased expression of TOPO1 protein and amplification of the TOP2A gene have been associated with treatment response in colorectal and ...

A rare epidermal growth factor receptor (EGFR) gene mutation in small cell lung carcinoma patients
Aim. Activating mutations in the epidermal growth factor receptor (EGFR) are predominantly detected in pulmonary adenocarcinoma and have been reported in small cell lung cancer (SCLC) for decades. This retrospective single-center study aimed to determine

Phosphorylation of pRb: mechanism for RB pathway inactivation in MYCN-amplified retinoblastoma. [PDF]
A small, but unique subgroup of retinoblastoma has been identified with no detectable mutation in the retinoblastoma gene (RB1) and with high levels of MYCN gene amplification.

The role of pfmdr1 in Plasmodium falciparum tolerance to artemether-lumefantrine in Africa [PDF]
Objective Artemether-lumefantrine (AL), presently the most favoured combination therapy against uncomplicated Plasmodium falciparum malaria in Africa, has recently shown to select for the pfmdr1 86N allele.
