Summary
Mast cells in benign prostatic hyperplasia (BPH) tissues promote prostate cell growth. Mast cell-derived interleukin-6 (IL-6) activates STAT3/Cyclin D1 signals, suggesting targeting mast cells could be a new BPH therapy.
Area of Science:
- Urology
- Immunology
- Cell Biology
Background:
- Mast cells are found in benign prostatic hyperplasia (BPH) tissues.
- The specific role of mast cells in BPH development is not fully understood.
Purpose of the Study:
- To investigate the role of mast cells in BPH development.
- To explore the molecular mechanisms by which mast cells influence BPH progression.
Main Methods:
- Comparison of mast cell infiltration in human BPH and normal prostate tissues.
- In vitro co-culture of BPH-1 prostate cells and mast cells.
- Analysis of molecular signaling pathways including IL-6, STAT3, and Cyclin D1.
Main Results:
- Increased mast cell presence in BPH tissues compared to normal prostate.
- Mast cells enhance BPH-1 cell proliferation and migration.
- Mast cell-derived IL-6 activates STAT3/Cyclin D1 signaling in BPH-1 cells, promoting proliferation.
- Inhibition of IL-6 or STAT3 partially reverses mast cell-induced BPH-1 cell proliferation.
Conclusions:
- Infiltrating mast cells promote BPH development through the IL-6/STAT3/Cyclin D1 pathway.
- Targeting mast cells may offer a novel therapeutic strategy for BPH.

Abnormal Proliferation
5.3K
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...

The Tumor Microenvironment
7.9K
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...

Intracellular Signaling Affects Focal Adhesions
3.7K
Integrins act both as extracellular input receivers and as intracellular processing activators. As their name suggests, integrins are entirely integrated into the membrane structure. Their hydrophobic membrane-spanning regions interact with the phospholipid bilayer's hydrophobic region. These membrane receptors provide extracellular attachment sites for effectors like hormones and growth factors. They activate intracellular response cascades when their effectors are bound and active.

Interactions Between Signaling Pathways
7.4K
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...

Intracellular Signaling Cascades
53.9K
Once a ligand binds to a receptor, the signal is transmitted through the membrane and into the cytoplasm. The continuation of a signal in this manner is called signal transduction. Signal transduction only occurs with cell-surface receptors, which cannot interact with most components of the cell, such as DNA. Only internal receptors can interact directly with DNA in the nucleus to initiate protein synthesis. When a ligand binds to its receptor, conformational changes occur that affect the...

mTOR Signaling and Cancer Progression
4.9K
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.
