Insights

Tumor-associated macrophages (TAMs) drive cancer progression. Nuclear factor-kappaB (NF-kappaB) signaling critically influences TAMs, impacting tumor growth, invasion, and metastasis.

Area of Science:

  • Immunology
  • Cancer Biology
  • Molecular Biology

Background:

  • Tumor-associated macrophages (TAMs) play a crucial role in cancer progression.
  • TAMs influence tumor growth, survival, invasion, metastasis, angiogenesis, and lymphangiogenesis.
  • Understanding the molecular mechanisms polarizing TAMs towards a pro-tumoral phenotype is critical.

Purpose of the Study:

  • To investigate the role of nuclear factor-kappaB (NF-kappaB) in regulating TAM function.
  • To reconcile current understanding of NF-kappaB's exact role in TAM polarization.

Main Methods:

  • Review of evidence from transgenic murine tumor models.
  • Analysis of NF-kappaB signaling pathway modifications and their impact on TAMs.

Main Results:

  • NF-kappaB is a master regulator impacting various pathways controlling TAM function.
  • Modifications in NF-kappaB signaling components alter the pro-tumor activities of TAMs.

Conclusions:

  • NF-kappaB signaling is a key determinant of TAM pro-tumoral functions.
  • Further research is needed to fully elucidate the complex role of NF-kappaB in TAM polarization and tumor progression.

NF-κB-dependent Signaling Pathway02:26

NF-κB-dependent Signaling Pathway

The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

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...
Immune Surveillance by NK Cells and Phagocytes01:25

Immune Surveillance by NK Cells and Phagocytes

Immune surveillance is an integral part of the innate immune system, involving the continuous monitoring of peripheral tissues to detect and respond to pathogens, infected cells, or cancerous cells. This surveillance is conducted primarily by natural killer (NK) cells and phagocytes, which employ distinct but complementary mechanisms to identify and eliminate threats.

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...
Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...
Abnormal Proliferation02:23

Abnormal Proliferation

Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...
