Expression levels of SNHG18 and their correlation with ovarian aging. A. Box plots of the dynamic expression of SNHG18 during folliculogenesis by the previous study. B. Violin plot of the relative expression level of lncRNA Snhg18 in single-cell RNA-sequencing data of 13-week and 52-week mouse ovaries. C. SNHG18 detection by RT-qPCR in granulosa cells from control, aged and POI women. D. The correlation between SNHG18 expression and AMH. E. The correlation between SNHG18 expression and female age. The data were expressed as the mean ± SD. ***, P < 0.001; ****, P < 0.0001
