Saudi Space Mission Detects Gene Activity Shifts in Microgravity

Experiments conducted on living cells aboard the International Space Station have identified significant changes in gene activity under microgravity conditions, offering new insights into biological processes linked to disease.

The research was carried out as part of the Saudi Arabia to Space mission, which examined how the space environment affects gene expression and how these changes can support medical research.

Led by Saudi scientist Khaled Abu Khabar Al-Qurashi, with participation from molecular biomedicine expert Wijdan Al-Ahmedi, the experiment focused on analysing messenger RNA within a cellular model designed to simulate multiple diseases.

Researchers said the findings could contribute to improved understanding of conditions affecting the musculoskeletal system, heart, nervous system and immune system. The results are also expected to support the development of more targeted treatments and therapies.

The study highlights the use of microgravity as a controlled research environment for examining cellular behaviour, enabling observations that are difficult to replicate under Earth-based conditions.
