In herding breeds of dogs there is a defined mutation called MDR1 - 1 ∆ (
multidrug resistance gene), also called ABCB1, which affects P - glycoprotein function.
These drug sensitivities result from a mutation in
the multidrug resistance gene (MDR1 gene.)
Signs of ivermectin toxicosis can occur in any breed but are most common in ivermectin - sensitive breeds such as collies and other herding breeds.20, 21 Ivermectin sensitivity is derived from a frameshift deletion mutation of
the multidrug resistance gene (MDR1; the most recent nomenclature is ABC ±), resulting in a severely truncated, nonfunctional protein product.
ABSTRACT: A mutation in the canine
multidrug resistance gene, MDR1, has previously been associated with drug sensitivities in two breeds from the collie lineage.
The expression of the tumoral
multidrug resistance gene (MDR1), which encodes P - glycoprotein, and NANOG, a stem - cell marker and a regulator of the expression of drug resistance genes, was determined using qRT - PCR.
In addition, they observed that parasites with multiple copies of
the multidrug resistance gene pfmdr1 tended to be less susceptible to several drugs, including DHA.
