Abstract

Many malignant lymphomas are characterized by recurrent genetic abnormalities. These include numerical abnormalities, deletions and reciprocal translocations. In this chapter, we have focused on the detection of chromosomal translocations in B cell lymphomas and discussed some trisomies in lymphomas and CLL. FISH is a well developed molecular method by which it is possible to detect numerical and structural chromosomal abnormalities. We addressed various aspects of metaphase, and especially interphase, FISH and also described the recently developed DNA fibre FISH technology. Using this method, it is possible simultaneously to detect and map chromosomal breakpoints. FISH is also compared with more conventional detection methods such as banding analysis, Southern blot analysis and PCR for the translocations t(8;14) and variant translocations in Burkitt's lymphoma, t(14;18) in follicular lymphoma and t(11;14) in MCL. Other breakpoints in B cell lymphoma are also discussed. It might be concluded that the rapid development in interphase and DNA fibre FISH will provide us with quick, easy and cheap tools to identify specific chromosomal translocations and other genomic abnormalities in human tumours.

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.

Cancer genomics approaches employ high-throughput technologies to identify the complete catalog of somatic alterations that characterize the genome, transcriptome and epigenome of cohorts of tumor samples. Discover the latest research using such technologies in this feed.

B-Cell Lymphoma

B-cell lymphomas include lymphomas that affect B cells. This subtype of cancer accounts for over 80% of non-Hodgkin lymphomas in the US. Here is the latest research.
