Salt Sensitive Hypertension

Initial studies found that female Dahl salt-sensitive (DS) rats exhibit greater blood pressure (BP) salt sensitivity than female spontaneously hypertensive rats (SHR). On the basis of the central role played by NO in sodium excretion and BP control, we further tested the hypothesis that blunted increases in BP in female SHR will be accompanied by greater increases in renal inner medullary nitric oxide synthase (NOS) activity and expression in response to a high-salt (HS) diet compared with DS rats. Gonad-intact and ovariectomized (OVX) female SHR and DS rats were placed on normal salt (NS; 0.4% salt) or HS (4% salt) diet for 2 wk. OVX did not alter BP in SHR, and HS diet produced a modest increase in BP. OVX significantly increased BP in DS rats on NS; HS further increased BP in all DS rats, although OVX had a greater increase in BP. Renal inner medullary NOS activity, total NOS3 protein, and NOS3 phosphorylated on serine residue 1177 were not altered by salt or OVX in either strain. NOS1 protein expression, however, significantly increased with HS only in SHR, and this corresponded to an increase in urinary nitrate/nitrite excretion. SHR also exhibit greater NOS1 and NOS3 protein expression than DS rats. These data indicate that female sex hormones offer protection against HS-mediated elevations in BP in DS rats but not SHR. We propose that the relative resistance to HS-mediated increases in BP in SHR is related to greater NOS expression and the ability to increase NOS1 protein expression compared with DS rats.

Male Sex

Background: Coronavirus disease-19 (COVID-19) is a newly emerged pandemic leading to a state of international alert with millions of infected individuals and thousands of deaths all over the world. Analysis of statistics and epidemiological data for the pandemic outcome pinpointed a puzzling influence of human sex on the heterogeneous outcome of COVID-19, where hospital admissions and mortality were higher among males than females. Two theories explained the observed male-biased COVID-19 mortality based on either dosage of immunoregulatory genes coded in X- chromosomes or on the abundance of the angiotensin-converting enzyme two (ACE2) receptors in males than females. Objective: In our study, we propose a third scenario through virtual screening of direct antiviral effects of sex hormones. Materials & Methods: Updated screening statistics from 47 countries displaying sex-disaggregated data on COVID-19 were employed and visualized in the form of heatmaps depicting sex difference effects on statistics of cases and deaths. Molecular docking and binding simulations of investigated sex steroids against COVID-19 specific proteins were investigated. Results: Analysis of COVID-19 sex-disaggregated data confirmed that male-biased mortality and computer-aided docking found unexpected female sex hormones biased binding against key targets implicated in the life cycle of COVID-19 compared to the male sex hormone testosterone. Other investigated steroids showed promising docking scores, while the male sex hormone exhibited the lowest affinity. Conclusion: Female sex hormones virtually exhibited direct COVID-19 effect. The proposed antiviral effect of sex hormones should be considered to explain the outcomes of mortality; moreover, the fluctuation of sex hormones influences sex and personal derived-differential response to COVID-19 infection.
