The RNA methyltransferase methyltransferase like-3 expression levels are significantly upregulated in chronic hexavalent chromium [Cr(VI)] exposure-transformed human bronchial epithelial cells. A, Representative Western blot analysis images for the selected N⁶-methyladenosine (m⁶A) writers, erasers, and reader proteins in passage-matched control cells and Cr(VI)-transformed cells. B–D, The quantitative results of Western blot analysis of m⁶A writers, erasers, and reader proteins in passage-matched control cells and Cr(VI)-transformed cells. The corresponding Western blot protein band intensities were quantified using the ImageJ software and normalized by the intensity of the β-actin protein band (means ± SD, n = 3). *p < .05.
