Jun 26, 2018 · Cancer cells' relationship with oxygen is a bit more complicated, and that realization has led to decades of research into whether oxygen is good for cancer or bad for it. The answers are still not definitive, but some have used the unknowns to fuel unsupported claims that certain types of oxygen therapies, including hyperbaric oxygen (HBO) therapy, can cure cancer.

Nov 22, 2019 · Another unproven idea about oxygen and cancer is that, since many tumors thrive in oxygen-deprived (hypoxic) conditions, giving cancer cells extra oxygen might shut them down or even kill them. That’s the notion behind hyperbaric oxygen therapy — oxygen administered to a patient in a chamber under high pressure to increase its concentration in the blood, as it sometimes done to improve ...
Jun 8, 2021 · Tumor cells have long been recognized as a relative contraindication to hyperbaric oxygen treatment (HBOT) since HBOT might enhance progressive cancer growth. However, in an oxygen deficit ...

Oct 21, 2016 · Direct Effects on Cells in Cell Culture Kalns4 and associates have reported the effects of HBO 2 on the growth of two prostate cancer cell lines in cell culture. In this study, both cell lines had their growth suppressed after exposure to 100% oxygen for 90 minutes at 3.0 ATA relative to normobaric controls by 8.1% and 2.7% respectively.

Hypoxic tumor cells are relatively insensitive to conventional therapy owing to cellular adaptations effected by the hypoxic microenvironment. Recent efforts have aimed to alter the hypoxic state and to reverse these adaptations to improve treatment outcome. One way to increase tumor oxygen tensions is by hyperbaric oxygen (HBO) therapy. HBO ...
Chunxia Chen found that ROS and lipid ROS levels in HT22 cells and PC12 cells decreased after HBO (pure oxygen, 0.25 MPa) treatment, thus protecting cells from oxygen-glucosedeprivation . However, Qin Hu et al. found that delaying HBO (2.5 atmospheres absolute) significantly increased ROS level, which may improve the long-term rehabilitation of stroke patients through the ROS/HIF-1 α/β ...

How do cancer cells respond to oxygen deprivation?
Jan 1, 2020 · A key component of the body’s oxygen-sensing system is a set of molecular hypoxia-inducible factors, or HIFs, which can respond to a need for more oxygen by turning on genes and proteins that recruit new networks of blood vessels. Cancer cells in a growing tumor can adapt to oxygen deprivation by hijacking these HIFs.
