CYP3A4 and CYP3A5genotyping by Pyrosequencing

Benchmark Molecular Haplotyping by Pyrosequencing

Several million SNPs have been identified and are available in the public databases. For most, no effect on gene function or expression is known. “Functional polymorphisms” refers to SNPs to which a putative effect on gene function or expression is attributed and implies that they are “non-silent” variations located in regions that are coding, regulatory, splice sites, or untranslated regions t...

Metabolic activation of benzodiazepines by CYP3A4.

Cytochrome P450 3A4 is the predominant isoform in liver, and it metabolizes more than 50% of the clinical drugs commonly used. However, CYP3A4 is also responsible for metabolic activation of drugs, leading to liver injury. Benzodiazepines are widely used as hypnotics and sedatives for anxiety, but some of them induce liver injury in humans. To clarify whether benzodiazepines are metabolically a...

Detection of heteroresistant Mycobacterium tuberculosis by pyrosequencing.

The ability of pyrosequencing to detect a resistant minority population of a heteroresistant Mycobacterium tuberculosis strain was investigated by performing a titration study. A mutant signal was noted only when the proportion of mutant DNA in the DNA target was 35 to 50%, showing that the sensitivity is significantly lower than that of phenotypic drug susceptibility test methods.

Analysis of Microbial Diversity by Amplicon Pyrosequencing

Analysis of splicing patterns by pyrosequencing

Several different mRNAs can be produced from a given pre-mRNA by regulated alternative splicing, or as the result of deregulations that may lead to pathological states. Analysing splicing patterns is therefore of importance to describe and understand developmental programs, cellular responses to internal or external cues, or human diseases. We describe here a method, Pyrosequencing Analysis of ...
