dc.description.abstract | Several researches have shown that cancer is caused by genetic mutations especially in genes involved in cell growth and regulation. Ras family members are frequently found in their mutated, oncogenic forms in human tumors. Mutant RAS proteins are constitutively active, owing to reduce intrinsic GTPase activity and insensitivity to GTPase-activating protein (GAPs). In total, activating mutations in the RAS genes occur in approximately 20% of all human cancers, mainly in codon 12, 13 or 61. Activating mutations in the NRAS gene not only result in the reduction of intrinsic GTPase activity but also in the induction of resistance against molecules inducing such activity. In this paper, we reported a rapid, simple and portable method for detecting the mutant types of NRAS genes codon 12 and 61 simultaneously by using bead-quantum dots (QDs) based multi-channel microfluidic chip. Probe DNAs are conjugated to bead-QDs and packed in the pillars of channels in the microfluidic chip. After injection of target DNAs and intercalating dyes, the fluorescence quenching of QDs by intercalating dye was observed due to FRET phenomena. The platform can be effortlessly applied in other biological and clinical areas. | - |
