Cancer, metastasis, and the epigenome

Area of Science:

• Oncology
• Genomics
• Cancer Biology

Background:

• Cancer is a leading global cause of death, with metastasis responsible for most fatalities.
• Understanding the genomic drivers of metastasis is crucial for improving patient outcomes.
• Current knowledge gaps exist regarding specific mutational landscapes that predict metastatic potential.

Purpose of the Study:

• To review critical needs in understanding cell state transitions and clonal selection in metastatic cancer.
• To examine the interplay between epigenetic states, genome structure, and oncogene/tumor suppressor misregulation.
• To discuss how advanced technologies aid in understanding oncogenic and metastatic potential.

Main Methods:

• Literature review focusing on cancer genomics, epigenetics, and genome structure.
• Analysis of current research on cell state transitions and clonal selection in metastasis.
• Discussion of recent technological advancements in studying domain-scale genome regulation.

Main Results:

• Metastasis is not solely driven by mutations; non-mutational genome re-organization plays a significant role.
• Epigenetic modifications and genome structural changes are implicated in cancer evolution and dissemination.
• Advanced technologies are providing deeper insights into the mechanisms of oncogenesis and metastasis.

Conclusions:

• Further research is needed to elucidate the genomic features driving metastasis.
• Non-mutational genomic alterations are critical factors in cancer progression and spread.
• Integrating epigenetic and structural genomics data is essential for a comprehensive understanding of metastatic potential.
