Hypoxia News and Research

RSS

Hypoxia is a condition in which there is a decrease in the oxygen supply to a tissue. In cancer treatment, the level of hypoxia in a tumor may help predict the response of the tumor to the treatment.

SARS-CoV-2 spike protein triggers cell signaling pathways in lung vascular cells

A new study published on the preprint server bioRxiv in October 2020 shows that vascular cells in the lung tissue begin to secrete signaling growth factors when exposed to just the spike protein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), without the rest of the viral components.

Pathways contributing to hypercoagulability in severe SARS‐CoV‐2 patients

In a study by researchers explored the possible mechanisms of the clotting disorder, focusing on the role of hypoxia-related activation of coagulation factors; cytokine storm, activation of neutrophils, and the release of neutrophil extracellular traps.

Hypoxic exosomes promote stemness in EWS sarcoma, indicates study

The cover for issue 40 of Oncotarget features Figure 5, "miR-210 silences the proapoptosis member CASP8AP2," by Kling, et al. which reported that hypoxic Ewing's sarcoma cells release exosomes that promote sphere formation, a stem-like phenotype, in EWS cells by enhancing survival.

Seropositive partners increase risk of COVID-19 but not obstetric complications in pregnant women

While earlier studies have shown the significance of serological testing for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in pregnant women, their partners have largely been excluded. Now, a new Danish study published on the preprint server medRxiv in September 2020 reports the impact of serologic testing in both pregnant women and their partners, as well as their newborns.
