Abstract:
:The study by Rieg et al. is the first to examine potassium handling in BK(-/-) mice, thereby addressing many unanswered questions regarding the separate roles of BK and ROMK channels in renal potassium secretion. This Commentary is an interpretation and opinion of their results, by two researchers who have been studying BK and ROMK, respectively, as potassium secretory channels in the distal nephron.

评论,杂志文章abstract:BACKGROUND:Autosomal-dominant medullary cystic kidney disease type 2 (MCKD2) is a tubulointerstitial nephropathy that causes renal salt wasting, hyperuricemia, gout, and end-stage renal failure in the fifth decade of life. The chromosomal locus for MCKD2 was localized on chromosome 16p12. Within this chromosomal region...
