reproductive system
• at 3 weeks of age, 3beta-HSD protein is detected not only in the interstitium (as in control ovaries) but also in the granulosa cells of small follicles (unlike in control ovaries); also, mRNA expression of LHR, aromatase and FSHR is increased whereas mRNA expression of Amh is reduced, suggesting premature differentiation of granulosa cells
• at 3 weeks of age, many developing follicles show asymmetric granulosa cells or no granulosa cells with cuboidal morphology
• at 1 week of age, the total number of developing follicles with multiple layers of granulosa cells is significantly lower than that in control ovaries (~44 versus ~205, respectively)
• at 3 weeks of age, the number of developing follicles is significantly reduced and many aberrant follicles with undifferentiated squamous granulosa cells are observed
• when follicles with 2-3 layers of granulosa cells are obtained from 2-week-old ovaries and cultured in vitro, only ~11% of follicles develop to the pre-ovulatory stage and most follicles are relatively small or exhibit detached oocytes after 11 days in culture, whereas ~80% of control follicles develop to the preovulatory stage with a notable antrum
• aberrant follicle development is likely due to premature differentiation and abnormal cell polarity establishment of granulosa cells
• however, granulosa cell proliferation is normal, as shown by Ki67 staining
• at 1 week of age, many primary follicles with asymmetric and disorganized granulosa cells are observed
• ovary size is dramatically reduced at 3 weeks of age
• ovulation rate of females is severely reduced with an average of only 2 oocytes obtained by natural ovulation versus 8 oocytes in control females
• after hormone stimulation, 3-week-old females release less than 5 oocytes versus ~64 oocytes released from control females
• only ~15% of plugged females become pregnant after mating with wild-type males versus 88.2% of control females

• 33% of males and 0% of females by 2 months of age and 100% of males and 43% of females at 4 months of age displayed glomerulosclerosis
• medullary regions of the kidneys had dilated tubules and protein casts, a few glomeruli with segmental sclerosis, and predominately glomeruli with global mesangial sclerosis
• glomeruli displayed severe thickening of the glomerular basement membrane
