Key result
Pulmonary endothelial cells exhibit sex-specific pathway differences in normoxia and hypoxia independent of sex hormones.
Why the study?
There is marked sexual dimorphism in the development and progression of pulmonary hypertension.

There is marked sexual dimorphism in the development and progression of pulmonary hypertension. We show differences in RNA and protein expression between female and male human pulmonary microvascular endothelial cells grown under conditions of physiological shear stress, which identify sex-different cellular pathways both in normoxia and hypoxia. Importantly, these differences were detected in the absence of sex hormone differences. The pathways identified may provide novel targets for the development of sex-specific therapies.

Kostyunina et al. (2023) studied Pulmonary hypertension. Normoxia and hypoxia vs. Female vs male cells was evaluated on Differences in RNA and protein expression. Transcriptomic and proteomic analysis of human pulmonary microvascular endothelial cells revealed sex-specific differences in cellular pathways under normoxia and hypoxia, independent of sex hormones.
