MMP2 and Nephropathy: A total of 34 and 32 of the differentially regulated transcripts in kidney cortex and medulla, respectively, have previously been suggested associated with kidney injury or radiation damage (Table 1), e.g. Mmp2, Cdkn1a, and Ccnd1. The strongest association with kidney damage-associated markers was found at 8 months for both tissues, with recurrent expression of e.g. Cdkn1a, S100a6, and Lcn2. At 4 and 8 months after injection, the highest number of kidney injury markers and/or radiation markers was found after 150 MBq.
