Resumo: |
The β-defensins are proteins most widely studied of the three subfamilies of defensins, because have extensive antimicrobial activity and are produced by several types of epithelial cells, thereby providing protection to the membranes of host cells. In mammals, in addition to their antimicrobial activity, these proteins act in the maturation of spermatozoa, in sperm capacitation, in protecting the sperm against the female immune response and specific and differential expression in reproductive tissues, thus suggesting an important role in reproduction and fertility. The radiation hybrid panel (RH panel) constructed for buffalo genome (BBURH5000) has been successfully used in mapping studies of buffalo chromosomes. The RH mapping strategy, in other words, use of RH panel associated statistical analysis, determines the linear order of markers on chromosomes and is an important tool for the construction of physical maps of high resolution genome and also in the construction of comparative maps between species. The present study has the purpose to use the BBURH5000 panel to map a set of β-defensins genes on buffalo chromosome 14 and the construction of a comparative map in silico between BBU14 and homologous bovine. To this end, we tested buffalo DNA sequences of primers for PCR from eight genes of β-defensins, located on bovine chromosome 13 (BTA13), which is homologous to BBU14. Of the markers tested, six amplified suitable PCR product to the mapping using BBURH5000 panel. However, two markers were excluded in step genotyping. The retention frequency of markers on the panel presented a variation of 16.66% with a marker BBD125 to 20.00% with markers BBD119 and BBD122. The comparative analysis in silico between the BBU14 RH map and the sequence map of BTA13 allowed to indicate the location of these markers on buffalo chromosome 14 |
