NINJ1 and oculocutaneous albinism type 1: Immunochemistry showed an upregulated expression of NINJ1 in ATN (Figure 1A), which was positively correlated with the serum creatinine (Scr) and blood urea nitrogen (BUN) levels (Figure 1B, C), hinting that increased NINJ1 expression may associated with AKI pathogenesis.
