Insights

Gastric cancer progression is driven by the tumor microenvironment (TME). Targeting TME cells and signaling pathways offers new therapeutic strategies for gastric cancer (GC).

Area of Science:

  • Oncology
  • Cancer Biology
  • Immunology

Background:

  • Gastric cancer (GC) is a prevalent global malignancy.
  • Late-stage diagnosis limits effective treatment options for GC.
  • The tumor microenvironment (TME) significantly influences GC progression and metastasis.

Purpose of the Study:

  • To review the role of TME cells and molecules in GC progression and metastasis.
  • To examine signaling pathways mediating cancer cell-TME interactions in GC.
  • To discuss therapeutic implications for targeting the GC TME.

Main Methods:

  • Literature review of TME components in gastric cancer.
  • Analysis of cellular and molecular interactions within the GC TME.
  • Synthesis of current understanding of GC TME-driven malignancy.

Main Results:

  • TME cells (inflammatory, immune, fibroblasts, vasculature) promote GC aggressiveness and metastasis.
  • Signaling pathways are crucial for cancer cell communication with the GC TME.
  • Understanding these interactions is key to developing targeted therapies.

Conclusions:

  • The TME is a critical regulator of gastric cancer malignant progression.
  • Targeting specific TME components and pathways holds promise for novel GC therapies.
  • Further research into GC TME mechanisms can lead to improved patient outcomes.

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...

Tumor Progression02:07

Tumor Progression

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
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...

Adaptive Mechanisms in Cancer Cells02:53

Adaptive Mechanisms in Cancer Cells

Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

Metastasis02:30

Metastasis

Metastasis is the spread of cancer cells from the original site to distant locations in the body. Cancer cells can spread via blood vessels (hematogenous) as well as lymph vessels in the body.
Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...

Mitogens and the Cell Cycle02:38

Mitogens and the Cell Cycle

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...
