Omics Studies of Tumor Cells under Microgravity Conditions

Area of Science:

• Space biology
• Cancer research
• Omics technologies

Background:

• Cancer is a complex disease with high mortality, and current understanding of its mechanisms remains incomplete.
• High-throughput omics and bioinformatics have advanced cancer research, but novel approaches are needed.
• Microgravity in space induces unique biochemical and molecular changes in human cancer cells.

Purpose of the Study:

• To review omics studies on tumor cells exposed to microgravity (real or simulated).
• To explore how microgravity influences cancer cell signaling pathways, growth, and metastasis.
• To identify innovative strategies for cancer research and treatment based on space studies.

Main Methods:

• Review of genetic, transcriptional, epigenetic, proteomic, and metabolomic studies.
• Analysis of tumor cells from various cancer types (brain, hematological, sarcomas, etc.).
• Inclusion of studies using real space conditions and simulated microgravity.

Main Results:

• Microgravity affects key cancer processes: proliferation, apoptosis, cell survival, adhesion, and migration.
• Space exposure alters biological aspects including the cytoskeleton, extracellular matrix, and growth factor signaling.
• Omics data from space-exposed cancer cells offer insights into fundamental cancer biology.

Conclusions:

• Space-based research provides a unique environment to study cancer mechanisms.
• Microgravity influences multiple facets of cancer cell biology, offering new therapeutic targets.
• This review highlights the potential of space research for developing novel cancer fighting strategies.
