The tumor microenvironment (TME) drives cancer progression and metastasis. Targeting TME components and developing better models are key to improving anti-cancer therapies and patient prognosis.
Area of Science:
- Oncology
- Cancer Biology
- Tumor Microenvironment Research
Background:
- Cancer development is intrinsically linked to the tumor microenvironment (TME).
- Tumor cells undergo genetic alterations leading to uncontrolled growth, apoptosis resistance, and the Warburg effect.
- These cellular changes induce TME conditions like hypoxia, oxidative stress, and acidosis, promoting extracellular matrix remodeling, stromal and immune cell responses, angiogenesis, and metastasis.
Purpose of the Study:
- To highlight the common features in the TME maturation of epithelial-derived tumors.
- To emphasize the role of exosomes secreted by TME cells in cancer progression.
- To underscore the impact of TME on prognosis and anti-cancer therapy efficacy, driving the need for novel therapeutic strategies.
Main Methods:
- Review of common TME maturation features in epithelial-derived tumors.
- Analysis of the role of exosomes in TME-driven cancer events.
- Examination of current therapeutic strategies targeting TME components.
- Evaluation of advanced TME modeling techniques for research.
Main Results:
- The TME significantly influences cancer development, metastasis, and therapeutic outcomes.
- Exosomes play a crucial role in mediating TME-associated cancer progression.
- Existing therapeutic strategies are being expanded to include combined therapies and nanomedicines.
- Novel TME models, such as tumor-on-a-chip and spheroids, are being developed for better preclinical investigation.
Conclusions:
- The TME is a critical determinant of cancer prognosis and treatment response.
- Targeting TME components offers promising avenues for enhanced anti-cancer therapies.
- Advanced TME models are essential for accurate preclinical research and therapeutic development.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

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.
