Mu Opioid Receptor Gene: New Point Mutations in Opioid Addicts
Introduction: Association between single-nucleotide polymorphisms (SNPs) in mu opioid receptor gene and drug addiction has been shown in various studies. Here, we have evaluated the existence of polymorphisms in exon 3 of this gene in Iranian population and investigated the possible association between these mutations and opioid addiction. Methods: 79 opioid-dependent subjects (55 males, 24...

متن کاملDNA rearrangements associated with reversion of bacteriophage Mu-induced mutations.
Excision of transposable genetic elements from host DNA is different from the classical prophage lambda type of excision in that it occurs at low frequency and is mostly imprecise; only a minority of excision events restores the wild-type host sequences. In bacteriophage Mu, a highly efficient transposon, imprecise excision is 10-100 times more frequent than precise excision. We have examined a...

متن کاملTruncated mu (mu') chains in murine IgM. Evidence that mu' chains lack variable regions
Secreted IgM was shown to contain truncated mu (mu') chains with an apparent molecular mass of approximately 55 kD. The estimated percentage of IgM heavy (H) chains in the mu' form ranged from less than or equal to 1% in the case of one tumor IgM protein (104E) to greater than or equal to 30% in normal serum IgM. Serum mu' chains lacked antigenic determinants characteristic of immunoglobulin va...
