High-mobility group box-1 (HMGB1) protein is involved in cellular processes and diseases like cancer. Overexpressed HMGB1, with its receptor, promotes tumor proliferation and metastasis, offering potential therapeutic targets.
Area of Science:
- Biochemistry
- Molecular Biology
- Oncology
Background:
- High-mobility group box-1 (HMGB1) protein, identified 33 years ago, has diverse cellular roles.
- Initially chromatin-associated, HMGB1 is also found in cytoplasm and extracellularly as a cytokine.
- HMGB1 is implicated in various diseases, including Alzheimer's, sepsis, arthritis, and cancer.
Purpose of the Study:
- To review the role of HMGB1 in cancer development and metastasis.
- To explore HMGB1's association with tumor proliferation and spread.
- To identify potential therapeutic targets related to HMGB1 in cancer.
Main Methods:
- Literature review of HMGB1's functions and disease associations.
- Analysis of studies linking HMGB1 overexpression to cancer progression.
- Examination of HMGB1's role in conjunction with its receptor for advanced glycation end products.
Main Results:
- HMGB1 overexpression, especially with its receptor, correlates with proliferation and metastasis in breast, colon, and melanoma.
- HMGB1 acts as a cytokine and differentiation factor.
- HMGB1 is implicated in tumor growth and spread.
Conclusions:
- HMGB1 plays a significant role in cancer development and metastasis.
- Targeting HMGB1 and its receptor presents a potential therapeutic strategy for various cancers.
- Further research into HMGB1's mechanisms in cancer is warranted.

Cancer-Critical Genes II: Tumor Suppressor Genes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
