Tumor-associated macrophages in cancers
Summary
Tumor-associated macrophages (TAMs) are key immune cells in tumors. M2 TAMs often dominate, driving tumor growth and metastasis, highlighting their potential as a novel cancer treatment target.
Area of Science:
- Immunology
- Oncology
- Cell Biology
Background:
- Tumor-associated macrophages (TAMs) are crucial immune cells within the tumor microenvironment.
- TAMs influence both tumor progression and regression.
- The tumor microenvironment dictates the polarization of macrophages between M1 and M2 phenotypes.
Purpose of the Study:
- To explore the role of TAMs in tumor progression and metastasis.
- To understand the dynamic balance between TAMs and tumor cells.
- To identify TAMs as potential diagnostic markers and therapeutic targets in cancer.
Main Methods:
- Analysis of leukocytic infiltrate in tumors.
- Characterization of macrophage phenotypes (M1/M2) within the tumor microenvironment.
- Investigation of TAM-tumor cell interactions.
Main Results:
- M2 macrophages are frequently the predominant TAM subset in various tumors.
- M2 TAMs are associated with promoting tumor progression and metastasis.
- The interaction between TAMs and tumor cells significantly impacts tumor development.
Conclusions:
- TAMs play a pivotal role in cancer progression.
- M2 TAMs are key drivers of tumor metastasis.
- Targeting TAMs presents a promising strategy for novel cancer therapies and clinical diagnosis.

02:17The Tumor Microenvironment
8.2K
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...

02:53Adaptive Mechanisms in Cancer Cells
7.4K
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.

03:03mTOR Signaling and Cancer Progression
5.1K
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.

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...

6.4K
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...
