Resistance to ACTs may evolve even when the two drugs within the combination are taken simultaneously and amplification of the mdr1 gene may contribute to this phenotype.
The reaction was continued for a final extension at 72°C for 10 min. Normalization was carried out simultaneously by amplification of EF-1α using an antisense primer 5'-CTGGCTGTAAGGTGGCTCAG-3' and a sense primer 5'-CATGTCGATTCTGGCAAGTC-3' under the same conditions described above.
cDNA integrity was checked simultaneously by amplification of the housekeeping gene HPRT1.
To selectively identify immune-induced genes we used the subtractive suppression hybridization (SSH) method which amplifies differentially expressed cDNAs and simultaneously suppresses amplification of common cDNAs.
Hui and coworkers [ 19] utilized array-CGH to simultaneously investigate amplification of 58 oncogenes throughout the genome of 15 NPC samples including five cell lines, two xenografts, and eight primary tumours.
In our study, the PNA LNA PCR clamp technique, which inhibits wt gene amplification and simultaneously enhances amplification of the mutated allele, achieved very high sensitivity (1 % of tumour cells for both exons), in accordance with other reports [ 6, 9, 24].
A significant proportion of these TRAV gene duplications seems to have occurred simultaneously with the amplification of the TRDV1 subgroup genes.
Another favourite advantage of our real-time PCR technology is the quantification of mutated DNA simultaneously, if the amplification of the wild-type DNA was completely suppressed as seen in Figure 3A.
By directly binding to promoters with NFAT, where it is thought to, i.e., actively suppress NFAT/AP-1-mediated gene transcription, NR2F6 simultaneously antagonizes the well-established amplification of Nfat2 transcription, together maintaining the level of DNA-bound NFAT proteins below what is required for robust transcriptional activation of the Il2 and Ifng promoters.
SSH is a polymerase chain reaction (PCR -based cDNA subtraction technique that allows selective amPCR -basedn of target cDNA while subtractionsly suppressing non-techniqueNA amplificathat.
