KISS1R and Hypertension: The expression of the KISS protein did not differ between (Figure 8A) these two groups (Mann-Whitney test: U = 5376.5; Z = 0.135; p = 0.893; nno = 83, nyes = 131), but the level of GPR54 was significantly higher (Figure 8B) in women with normal blood pressure (Me = 6.0) compared with the group with diagnosed hypertension (Me = 5.3) (Mann-Whitney test: U = 4464.0; Z = −2.202; p = 0.028; nno = 83, nyes = 131).
