In future more clinical studies are warranted to confirm the prognostic role of mir-21 before its practical implementation in management of cancer. The realization that certain subtypes of leukemia are invariably associated with recurrent genomic abnormalities was a seminal discovery in leukemia research. This was first recognized in conjunction with chronic myeloid leukemia and the paradigmatic Philadelphia chromosome. Nowadays we know that this Epothilone B<\/a> is a widespread phenomenon. The determination of genotype has become essential for diagnosis, stratification, treatment planning and prognosis of hematological malignancies. Particularly in infant and childhood leukemia almost half of all diagnosed cases are characterized by the persistent appearance of distinctive chromosomal translocations. Because of the importance of these genetic markers for clinical management a series of methods has been devised that allows the detection of the underlying genetic lesion. Cytogenetics and fluorescent in situ hybridization are generally applied to demonstrate the presence and overall structure of genomic alterations. However, both approaches require mitotic cells, cumbersome experimental procedures and experienced operators for success. Alternative methods using archived genetic material have also been developed. Since most translocations create inframe fusion proteins there are only a limited number of exons within both fusion partners that can be joined productively. This fact has been exploited by PCR based methods that use RNA\/ cDNA as Eltrombopag Olamine<\/a> template. In this way the number of primer pairs necessary to interrogate for the presence of a specific translocation is limited and the expected amplification products can be predicted. The drawback is the labile nature of RNA that often precludes successful amplification from stored or aging samples. To avoid this problem DNA based methods have been explored. Yet, the actual genomic breakpoints are usually unknown and they are distributed over a large stretch of intronic sequences. This mandates either the use of an unwieldy number of different primer pairs or long range PCR strategies with the disadvantage of non-quantifiable amplicons of unknown length that may well exceed the practicable limits of current PCR.<\/p>\n","protected":false},"excerpt":{"rendered":"
