The Tumor Microenvironment02:17

The Tumor Microenvironment

7.8K
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

Cancer Therapies02:49

Cancer Therapies

10.2K
Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
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...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

8.9K
The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
There are several types of targeted therapies against...

Cancer Stem Cells and Tumor Maintenance

6.0K
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.
Cancer stem cells are thought to originate from tissue-specific normal stem cells or progenitor cells. The normal stem cells usually reside in...

Cancer-Critical Genes II: Tumor Suppressor Genes

9.8K
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
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.
Such genes that act...

Background:

  • The tumor microenvironment (TME) comprises cellular and non-cellular elements crucial for tumor progression.
  • The TME's role in cancer development and its dynamic changes during therapy are increasingly recognized.
  • TME remodeling by cancer therapies can lead to enhanced responses or acquired drug resistance.

Purpose of the Study:

  • To review the key components of the tumor microenvironment.
  • To discuss TME remodeling in response to anti-cancer treatments.
  • To summarize strategies for modulating the TME to improve therapeutic efficacy.

Main Methods:

  • Literature review of existing research on tumor microenvironment.
  • Analysis of studies detailing TME composition and dynamics.
  • Synthesis of findings on TME modulation strategies.

Main Results:

  • The TME is a complex, dynamic system influencing cancer progression.
  • Anti-cancer therapies significantly alter the TME, impacting treatment outcomes.
  • Targeting TME components can enhance treatment response and overcome resistance.

Conclusions:

  • Understanding TME dynamics is critical for effective cancer therapy.
