Fig. 1. Rps26 is highly expressed in ovarian oocytes and is indispensable for female fertility.

a Real-time PCR analyses showing relatively high levels of Rps26 mRNA in GV oocytes and adult testis. The Rps26 mRNA levels of all samples were compared to the Rps26 mRNA level in the lung. b Western blot analyses showing relatively high expressions of Rps26 protein in the adult ovary, testis, and liver. The Rps26 protein levels of all samples were compared to the Rps26 protein level in granulosa cells. Protein levels were quantified with the Image J software, and the average value of each sample was calculated using Microsoft Office Excel. c Representative images of the western blot analysis from b showing the expression of the Rps26 protein in different tissues and organs. d Western blot analysis showing that expression of Rps26 protein in GV oocytes from the ovaries of Rps26fl/fl/Gdf9-Cre mice was undetectable compared with that in Rps26fl/fl mice. e mRNA sequencing analysis showing significantly decreased Rps26 mRNA expression in the oocytes of Rps26fl/fl/Gdf9-Cre mouse ovaries at PD14 and PD28. **p< 0.01 as calculated by two-tailed Student’s t-tests. f, g Immunofluorescence results for the expression of Rps26 in oocytes collected from Rps26fl/fl mice (f) and Rps26fl/fl/Gdf9-Cre mice (g). h Cumulative numbers of pups per female of the indicated genotypes. Rps26fl/fl/Gdf9-Cre females were infertile
