  8. Hadchouel J, Ellison D, Gamba G. Regulation of Renal Electrolyte Transport by WNK and SPAK-OSR1 Kinases. Annu Rev Physiol. 2016;78:367-89 pubmed publisher
    ..In contrast, the process of regulating the channels is independent of SPAK-OSR1. We present a review of the remarkable advances in this area in the past 10 years. ..
  9. Barba Navarro R, Tapia Silva M, Garza García C, Lopez Giacoman S, Melgoza Toral I, Vazquez Rangel A, et al. The Effect of Spironolactone on Acute Kidney Injury After Cardiac Surgery: A Randomized, Placebo-Controlled Trial. Am J Kidney Dis. 2017;69:192-199 pubmed publisher
    ..Our trial demonstrated that spironolactone was not protective for AKI associated with cardiac surgery and there may be a trend toward risk. ..
