Serum starvation induces sexual dimorphisms in secreted proteins of human umbilical vein endothelial cells (HUVECs) from twin pairs

Abstract: There is growing evidence for sex and gender differences in the clinical manifestation and outcomes of human diseases. Human primary endothelial cells represent a useful cardiovascular model to study sexual dimorphisms at the cellular level. Here, we analyzed sexual dimorphisms of the secretome after serum starvation using human umbilical vein endothelial cells (HUVECs) from twin pairs of the opposite sex to minimize the impact of varying genetic background. HUVECs were starved for 5 and 16 h, respectively, and proteins of the cell culture supernatants were analyzed by tandem mass spectrometry. Altogether, 960 extracellular proteins were identified of which 683 were amendable to stringent quantification. Significant alterations were observed for 455 proteins between long‐term and short‐term starvation and the majority were similar in both sexes. Only 5 proteins showed significant sex‐specific regulation between long‐versus short‐term starvation. Furthermore, 19 unique proteins with significant sexual dimorphisms at the same time points of serum starvation were observed. A larger number of proteins, for example tissue factor inhibitor 2 (TFPI2), displayed higher levels in the supernatants of females compared to male cells after long term serum starvation that might point to higher adaptation capacity of female cells. The overall results demonstrate that male and female cells differ in their secretome.
