Insights

Stromal cells within the tumor microenvironment influence cancer growth and metastasis. Targeting tumor-stromal cell interactions with small molecules offers a promising anti-tumor strategy.

Area of Science:

  • Oncology
  • Cell Biology
  • Cancer Research

Background:

  • The tumor microenvironment (TME) includes tumor cells, normal cells, and extracellular matrix.
  • Normal cells in the TME regulate cancer growth, metastasis, cancer stem cell maintenance, and metastatic niche formation.
  • Current anti-cancer strategies often target angiogenesis and immune responses within the TME.

Purpose of the Study:

  • This review focuses on the role of stromal cells, a key component of the TME.
  • To explore how stromal cells influence cancer cell growth and metastasis.
  • To discuss the potential of targeting tumor-stromal cell interactions for cancer therapy.

Main Methods:

  • Review of existing literature on tumor microenvironment and stromal cells.
  • Analysis of mechanisms by which stromal cells regulate cancer cell behavior.
  • Discussion of therapeutic strategies targeting stromal cell interactions.

Main Results:

  • Stromal cells, specifically fibroblast-like cells, are common in the TME.
  • Stromal cells can positively and negatively regulate cancer cell growth via adhesion and secreted factors.
  • These interactions are critical for cancer progression and metastasis.

Conclusions:

  • Stromal cells play a significant role in regulating cancer progression.
  • Modulating tumor-stromal cell interactions is a viable therapeutic approach.
  • Small molecules targeting these interactions represent a potential new avenue for anti-tumor strategies.

The Tumor Microenvironment02:17

The Tumor Microenvironment

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...

Drugs that Stabilize Microtubules01:15

Drugs that Stabilize Microtubules

Microtubules are dynamic structures that undergo cycles of catastrophe and rescue. The microtubules play a central role in cell division by forming the spindle apparatus for segregating the chromosomes. This makes them ideal targets for regulating dividing cells in tumors and malignant cancer cells. Microtubule stabilizing drugs help stabilize the microtubule formation and promote its polymerization. Paclitaxel was the first microtubule stabilizing agent used as anticancer drug in chemotherapy...

Targeted Cancer Therapies02:57

Targeted Cancer Therapies

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...

Tumor Immunotherapy01:27

Tumor Immunotherapy

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

Drugs that Destabilize Microtubules

Microtubules are dynamic structures and can be regulated by microtubule targeting agents (MTAs). Microtubule destabilizing drugs are a class of MTAs that destabilize and prevent microtubules' polymerization. Both natural and synthetic chemicals can be found under this class of drugs. Vincristine and vinblastine, two vinca alkaloids, and colchicine were among the first to be discovered. These drugs can affect cells in various ways, either by inducing a change in cell morphology, preventing...
