  • Thiamine, known also as vitamin B 1 , is an essential nutrient for all mammals, yet it was unclear if the interaction between FeLV-A and the newly-characterized feline thiamine transporter contributes to the pathologies resulting from FeLV-A infection. (fredhutch.org)
  • To test the effects of FeLV-A on thiamine uptake and growth of feline cells, Drs. Mendoza and Overbaugh teamed up with Dr. Dusty Miller, who leads his own lab group in the Human Biology Division. (fredhutch.org)
  • Thus, to fully understand potential interactions between FeLV infection and thiamine uptake, Mendoza cloned and sequenced the cat ortholog corresponding to the second transporter (THTR2) as part of his Ph.D. thesis research. (fredhutch.org)
  • He then tested whether feline THTR2 (feTHTR2) could function as a receptor for FeLV-A. He expressed feTHTR2 in cultured mouse fibroblasts and showed that these cells did not allow the entry of FeLV-A. In the same experiment, mouse fibroblasts expressing feline THTR1 (feTHTR1) were highly permissive of FeLV-A infection. (fredhutch.org)
  • Thus, feTHTR1 and feTHTR2 both function in thiamine uptake at levels similar to that of human THTR1, but only feTHTR1 functions as a cell-entry receptor for FeLV-A in cats. (fredhutch.org)
  • To understand which feline cells might be most susceptible to the inhibitory and possibly toxic effects of FeLV-A on thiamine uptake, the authors examined the expression patterns of feTHTR1 and feTHTR2 in several different cat tissues. (fredhutch.org)
  • Finally, Mendoza examined the effects of FeLV infection on growth of a feline embryonic fibroblast cell line (AH927) that naturally expresses feTHTR1 but not feTHTR2. (fredhutch.org)
