a Effect of 1 week LIM on the expression of 43 collagen genes in C57BL6J mouse sclerae (NL: n = 8, −30D: n = 7). No Lens group was assigned a value of 1.0. *p < 0.05 compared to each No Lens group; Student’s two-tailed t-test (Exact p values are as follows. 4a2: p = 0.023, 4a3: p = 0.001, 6a1: p = 0.008, 6a2: p = 0.027, 6a5: p = 0.024, 7a1: p = 0.009, 8a1: p = 0.041, 8a2: p = 0.024, 11a2: p = 0.022, 12a1: p = 0.048, 15a1: p = 0.036, 18a1: p = 0.038). b Effect of 3 weeks LIM on the expression of 43 collagen genes in C57BL6J mouse sclerae (NL: n = 8, −30D: n = 7). No Lens group was assigned a value of 1.0. *p < 0.05 compared to each No Lens group; Student’s two-tailed t-test (Exact p values are as follows. 1a1: p = 0.012, 4a3: p = 0.009, 24a1: p = 0.017). c 4-PBA instillation cancels LIM-induced decrease in COL1A1 protein expression in sclerae (n = 4, each sample pooled 3 sclerae). NL: No Lens control, −30D: minus 30 D lens-wearing eye. d The effect of LIM and 4-PBA instillation on Col1a1 mRNA expression in sclerae (n = 6, respectively). The p values were determined by Generalized Estimating Equations. e 4-PBA instillation cancels LIM-induced increase in Col4a3, Col8a2, Col11a2, and Col15a1 mRNA expression evaluated by qPCR in sclerae (n = 6 per group); The p values were determined by two-tailed Generalized Estimating Equations. f Transmission electron microscopy images of sclerae collagen fiber in No lens control (NL) and −30 D lens worn (−30D) sclera of PBS or 4-PBA instilled C57BL6J mouse. Representative images of three biologically independent samples; scale bar, 200 nm. g 100% stacked bar charts of scleral collagen fiber area (n = 3 biologically independent samples). Five images from one sclera. Fiber area was measured using ImageJ software. Source data are provided as a Source Data file.
