Figure 7. Olfr1437 and Olfr235 are male-enriched and respond to the macrocyclic musk molecule CPD.

(A) Volcano plot comparing expression of Olfrs between 43-week-old sex-separated male and female mice. Olfr1437 and Olfr235 and are highlighted in red. The red dashed line indicates an FDR = 0.05. Data are from n = 3 male and n = 3 female mice. (B) Volcano plot comparing expression of Olfrs between 43-week-old sex-combined male and female mice. (C) Longitudinal plotting of the mean and SEM of proportions of reads aligned to Olfr1437 and Olfr235 in sex-separated and sex-combined male and female mice. (D) Structure of macrocyclic musk odorant cyclopentadecanone (CPD). (E) Volcano plot showing the results of pS6-IP-Seq using 100 mM CPD diluted in ethanol as stimulus. Olfr1437 and Olfr235 are highlighted in red and enriched. The red dashed line indicates an FDR = 0.05. Data are from n = 3 control (diluent-exposed) mice and n = 3 experimental (odor-exposed) mice.

Figure 7—figure supplement 1. Male over-expression is also consistent with a difference in the number of cells expressing Olfr1437 between male and female mice.

(A) Left: representative in situ mRNA hybridization pictures probing for the expression of Olfr1437 in 43-week-old sex-separated male (top) and female (bottom) mice. Scale bars indicate 50 μm. Right: summary data showing mean and SEM of the density of OSNs expressing Olfr1437 in 43-week-old sex-separated male (top) and female (bottom) mice. An unpaired two-tailed t-test revealed statistical difference (****p < 0.0001) between males and females. Data are from n = 3 male and n = 3 female mice.
