Chromosome translocation as a cause of familial mongolism. Lancet. 2:678-680. [Entrez-PubMed link] Familial mongolism was an early term for Down syndrome. This early paper examines evidence for non-disjunction Down syndrome. Engles WR. 1983. The P family of transposable elements in Drosophila. Annu Rev Genet. 17:315-344. [Entrez-PubMed link] This review article summarizes much of what was known regarding P elements until the early 1980s. It sets the stage for much of the work on hybrid dysgenesis in the next decade. Kleckner N. 1981. Transposable elements in prokaryotes. Annu Rev Genet. 15:341-404. [Entrez-PubMed link] A review article on TEs in bacteria. Contains discussions of Is elements and Tn. McClintock B. 1950. The origin and behavior of mutable loci in maize. Proc. Natl Acad Sci USA. 36:344-355. [Full text link] McClintock’s groundbreaking paper that first introduced the concept of transposition of heterochromatin from one area of the genome to another as an explanation for “mutable loci”. McClintock B. 1953. Induction of instability at selected location in maize. Genetics. 38:579-599. [Full text link] 1 In this follow-up to her 1950 manuscript, McClintock makes a detailed examination of the Ds-Ac loci in corn to provide additional evidence of transposition. Recent Reviews and Research Articles on these Topics, with Special Emphasis on the Use of Transposable Elements as Tools for Molecular Genetic Analysis Selected Readings: Collier LS, Carlson CM, Ravimohan S. 2005. Cancer gene discovery in solid tumors using transposon-based somatic mutagenesis in the mouse. Nature. 436(7048): 272-276.[Entrez-PubMed links] This article describes the use of the Sleeping Beauty transposon to generate lossof-function or gain-of-function mutations to study the potential influence of target genes in cancer. Obe G, Pfeiffer P, Savage JR, et al. 2002. Chromosomal aberrations: formation, identification and distribution. Mutat Res 504(1-2):17-36.[Entrez-PubMed link] The research presented in this paper uses FISH to examine the areas of chromosomes that are potential hot spots for chromosomal structural changes. Seregaza Z, Roubertoux PL, Jamon M and Soumireu-Mourat B. 2006. Mouse models of cognitive disorders in trisomy 21: a review. Behav Genet. 36(3): 387404 [Entrez-PubMed link] By using homology maps between the mouse and humans, this paper studies specific regions that may play a role in trisomy-21 behavioral phenotypes.
