Análise comparativa de PRNP 12bp e 23bp indels em bovinos Aberdeen Angus, Aberdeen Angus x Hereford, Holstein Friesian e Crioulo Uruguaio saudáveis

Autoria SCIMAGO INSTITUTIONS RANKINGS

RESUMO:

A encefalopatia espongiforme bovina (EEB) é uma doença neurodegenerativa progressiva transmissível dos bovinos, caracterizada pelo acúmulo no cérebro de uma isoforma patológica (PrpSC) da proteína priônica celular (PrpC). Dois polimorfismos de inserção/deleção no gene PRNP (23bp no promotor e 12bp no íntron 1) foram associados à resistência ou suscetibilidade à doença. O objetivo deste trabalho foi analisar a distribuição desses polimorfismos em 214 bovinos sadios, pertencentes a quatro diferentes grupos raciais (Aberdeen Angus, Aberdeen Angus x Hereford, Holstein Friesian e Crioulo Uruguaio). As amostras de DNA foram amplificadas por PCR de tempo final. Uma alta frequência dos alelos e haplótipos associados à suscetibilidade à BSE (del12 e del23 e del12-del23, respectivamente) foram encontrados nos animais Aberdeen Angus, Aberdeen Angus x Hereford e Holstein Friesian, enquanto o gado Crioulo Uruguaio apresentou maior frequência dos alelos e haplótipos associados à resistência à BSE (ins12 e ins23 e ins12-ins23, respectivamente). Esses dados podem indicar uma maior resistência genética do gado Crioulo Uruguaio à BSE em comparação com as outras raças analisadas, reforçando seu valor como recurso zoogenético.
