Low gravity kills cancer cells? Tests on the ISS will provide the answer

Is it coming very expensive and available only to selected, but at the same time a very effective method of fighting cancer? It looks like it, though more information is still needed about how our body behaves in space.

We’ve been sending people into space for over half a century, but we still know relatively little about how low-gravity environments affect our physiology. Therefore, a group of Australian researchers conducted special simulations and, as it turned out, staying in a low-gravity environment can be a recipe for getting rid of most cancer cells from the body without having to take medication. The results are so promising that the next step is to conduct appropriate experiments at the International Space Station.

Until now, there have not been many similar tests on the ISS, and it seems that low gravity has a much greater impact on living organisms and human physiology than we could have expected. Although NASA had previously studied cellular changes in mice and mussels during space travel, to obtain information about the potential effects of low gravity on humans, the main reason was that we could see vision defects over time. Then came the time for research on the twins, one of which remained on Earth and the other flew to the ISS, which brought answers to many important questions, but so far few people were interested in the effects of low gravity on cancer cells.

So, the topic was decided to explore the biomedical engineer of the University of Technology Sydney, Joshua Chou, who conducted preliminary research in his laboratory, using a microgravity simulator to observe the behavior of cancer cells. The professor and one of his students subjected microgravity for 24 hours to ovarian, nasal and pulmonary cancer cells to find out that 80-90% of them were simply killed. Researchers believe that the lack of gravitational force affects how cells communicate with each other and prevents them from sensing the environment.

According to Chou: – I have to explain here that microgravity also affects other cells, such as bones, which is why astronauts have a problem with them. However, different tissues and organs in the body react differently to it, and we’ve noticed that in addition to bones, cancer cells are also super-sensitive to microgravity. We do not yet know why this is happening, but an experiment on the ISS, which is planned for next year, can give more answers torrent sites links directory. Special tumor cells will be packed into a device smaller than a pack of tissues, and then tested for ISS for a week.

Sending patients for space therapy seems like a crazy idea, but Chou reassures that it is more about learning some mechanisms that can then be reproduced on Earth and used to treat cancer. According to the author of the study: – What we are working on is to work together with current therapies, not replace them. We expect that we will be able to increase the effectiveness of currently used drugs to give the patient an advantage by interrupting the normal life cycle of cancer. Since his cells will no longer be able to work as a team, it will be much easier to defeat them.
