Köpekler, insanlarlaortak bir çevreyi paylaşır ve belirli köpek ırklarının hastalıkları hakkındabilgi, insan kanser çalışmaları için bir model geliştirmede çok yararlıdır.EST'ler, bir organizmanın transkribe edilen genomunun bir parçasını temsil ederve mikrosatellitleri tanımlamak için önemli bir kaynaktır. Tekrarlayan DNAdizilerini içeren Basit Dizi Tekrarları (SSR'ler) veya mikrosatellitler,bilinen en güçlü genetik belirteçler arasındadır. EST-SSR'lerin gelişimi,genomik çalışmalar için hızlı, verimli ve düşük maliyetli bir seçenek halinegelmiştir. Bu çalışmada, 2304 EST içeren Terrier köpeğin meme bezi dokusununEST koleksiyonundan SSR'lerin belirlenmesi için; Web tabanlı sürümleri olan vekolayca erişilebilen SSRIT ve IMEx yazılımları kullanılmıştır. SSRIT, 2 ila 10baz uzunluğundaki motifleri bulur ve tekli nükleotid motiflerini ortadankaldırarak minimum tekrar sayısını ayarlar. IMEx mükemmel ve kusurlu mikrosatellitleriayrı ayrı bulur. Farklı uzunluklarda 1 ile 6 arasındaki motifleri bulabilir veminimum tekrar sayısı ayarlanabilir. Ek olarak, istenen SSR bölgesi için uygunprimer tasarlanabilir. Normal doku EST'leri için 2, 3, 4, 5 ve 6 nükleotidli motiflerbulunurken, tümörlü doku EST'leri için 5 nükleotidli motif bulunamamıştır.

Dogs share a commonenvironment with humans and knowledge of the specific dog breed diseases isvery useful in developing a model for human cancer studies. ESTs represent partof the transcribed genome of an organism and are an important resource foridentifying microsatellites. Simple Sequence Repeats (SSRs), ormicrosatellites, which contain repetitive DNA sequences, are among the mostpowerful genetic markers known. The development of EST-SSRs has become a fast,efficient, and low-cost option for genomic studies. In this study, to determineSSRs from EST libraryof mammary gland tissue of the Terrier dog that has 2304ESTs; SSRIT and IMEx software, which have web-based versions and are easilyaccessible, were used. SSRIT finds motifs from 2 to 10 base lengths and adjuststhe minimum number of repeats by eliminating single nucleotide motifs. IMExfinds perfect and imperfect microsatellites separately. It can find motifs ofdifferent lengths from 1 to 6 and the minimum number of repeats can be set. Inaddition, the appropriate primer for the desired SSR region can bedesigned. The 2, 3, 4, 5 and 6nucleotide motifs were found for normal tissue ESTs whereas 5 nucleotide motifswere not found for tumoral tissue ESTs.
