Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Creatinine is a widely accepted biomarker for renal toxicity, but its renal clearance via transporter-mediated active secretion is significant. For a given new chemical entity, therefore, elevations in serum creatinine (SCr) can be caused by the inhibition of renal transporter(s) without renal toxicity. In the present study, an effort was made to assess the correlation between the inhibition of renal transporters in vitro and elevations in SCr. A total of 15 compounds were chosen based on their known effect on SCr and minimal impact on glomerular filtration rate. Their inhibition potencies against the major creatinine renal transporters, including organic cation transporter 2, organic anion transporter 2, and 2 forms of multidrug and toxin extrusion (MATE1 and MATE2K), were assessed in transporter-transfected cell lines using creatinine as a probe substrate. Collectively, the data suggest that the observed elevations in SCr can be attributed to the inhibition of renal transporter(s), but inhibition of renal transporters does not necessarily lead to elevated SCr. Thus, renal transporter inhibition data can be used to rationalize SCr changes. Additionally, differing renal transporter inhibition potencies using creatinine and metformin as probe substrates suggest that substrate-dependent inhibition exists for some compounds.
