Although the applications of LC MS or LC MS/MS to the molecular mass measurement, sequence determination, DNA adducts identification, detection of mutations and characterization of covalent and/or noncovalent DNA/RNA complexes have been comprehensively reviewed in a few excellent review papers.
This study presents a detailed analysis of the persistence of defined DNA adducts in spermatozoa following exposure to B[a]P at different stages of spermatogenesis, including the stem cell stages, along with stage specific analyses of de novo germ line mutations and characterization of mutants.
Although progress has been made in identifying specific differentially expressed genomic regions contributing to adaptive divergence, identification of specific mutations, and characterization of interactions among genomic regions, remains a major challenge for future work.
Here, we report p16 mutation detection and characterization in a prospective cohort study of 304 patients with BE and from 19 patients for which esophagectomy samples were available.
Colonies that formed were selected and back-crossed with wild-type cells and the resulting diploids were subject to meiotic analysis to verify that the suppressing mutations were extragenic and characterization of secondary phenotypes associated with the suppressing mutations, in this case cold-sensitivity and poor growth on media containing glycerol.
In their paper, " A DSPP mutation causing dentinogenesis imperfecta and characterization of the mutational effect," S. K. Lee et al. identified a mutation in exon 2 of DSPP in association with type III DGI in a Korean family.
Significant advances in our understanding of how GPI-T recognizes its signal sequences are needed to understand whether or not this arginine causes favourable or unfavourable interactions; mutation of this residue and characterization using the INV assay described herein will offer some insight.
The characterization of new gene models and splicing variations are easier to predict, as well as the detection and characterization of mutation sites [ 11].
Pshezhetsky, A. V. et al. Cloning, expression and chromosomal mapping of human lysosomal sialidase and characterization of mutations in sialidosis.
In the absence of crystal available for the full-length thyrotropin receptor, knowledge of its structure and functioning has benefitted from the identification and characterization of mutations in patients with various thyroid dysfunctions.
