Abstract:
In spite of the great advances made on the knowledge of cancer etiology and the significant breakthroughs in terms of treatment, complete remission is obtained in only around half of cancer patients. In fact, therapies that appear successful for some cancers are totally unfruitful for others, and some cancer types still remain incurables. In order to develop new therapies suitable to these tenacious cancers, we need to renew our view on cancer and to revise some old paradigms and "false friends" that can hide unexpected new therapeutic targets. A good example of these paradigms is the role of the cell stress response in tumor progression. Indeed, a number of studies has been devoted to the pivotal tumor suppressor function of some players of this response, of which the p53 protein is the best example. Nevertheless, during tumor progression and metastasis, the cancer cell faces many stresses imposed by tumor microenvironment and its survival will be conditioned by an efficient cell stress response. This review is consecrated to the role played by a pivotal actor of the cell stress response, the p8 protein, during carcinogenesis. We will recapitulate the data available on its different cell functions and the assets p8 confer to the cancer cell in terms of growth, drugs resistance and metastasis formations.
Insights
The p8 protein, a key player in cell stress response, surprisingly aids cancer cell growth, drug resistance, and metastasis. Revisiting its role may reveal new therapeutic targets for incurable cancers.
Area of Science:
- Oncology
- Molecular Biology
- Cellular Stress Response
Background:
- Despite advances, many cancers remain incurable, necessitating novel therapeutic strategies.
- The role of cell stress response in cancer progression is complex, with some proteins acting as tumor suppressors.
- Cancer cells must overcome microenvironment stresses for survival and metastasis, relying on an efficient stress response.
Purpose of the Study:
- To review the multifaceted roles of the p8 protein in carcinogenesis.
- To explore how p8 influences cancer cell survival, drug resistance, and metastasis.
- To identify p8 as a potential therapeutic target for aggressive cancers.
Main Methods:
- Literature review of studies on p8 protein function in cancer.
- Analysis of data on p8's impact on cancer cell growth and drug resistance.
- Examination of p8's role in metastasis formation.
Main Results:
- The p8 protein, a critical component of the cell stress response, confers advantages to cancer cells.
- p8 enhances cancer cell proliferation, promotes resistance to therapies, and facilitates metastasis.
- Evidence suggests p8's function shifts from tumor suppression to tumor promotion during cancer progression.
Conclusions:
- The p8 protein is a significant factor in tumor progression and metastasis.
- Understanding p8's pro-cancerous functions is crucial for developing new anti-cancer therapies.
- Targeting the p8 protein may offer a novel strategy against tenacious and incurable cancers.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...
