Summary
Androgen receptor (AR) and insulin-like growth factor 1 (IGF1) signaling pathways cooperate in prostate cancer development. Understanding these interactions offers new therapeutic targets for prostate cancer.
Area of Science:
- Oncology
- Molecular Biology
- Endocrinology
Background:
- Androgen receptor (AR) signaling is crucial for prostate cancer initiation and progression.
- Insulin-like growth factor 1 (IGF1) signaling also plays a significant role, supporting both androgen-dependent and independent prostate tumors.
- Interactions between AR and IGF1 pathways are implicated in prostate tumorigenesis.
Purpose of the Study:
- To elucidate the intricate crosstalk between androgen and IGF1 signaling axes in prostate cancer.
- To identify potential therapeutic strategies by understanding these molecular interactions.
Main Methods:
- Analysis of existing clinical and experimental data on AR and IGF1 signaling in prostate cancer.
- Investigating the augmentation of IGF1 receptor transcription by androgen-AR signaling.
- Examining the modulation of IGF1 secretion via IGF-binding protein 3 expression.
Main Results:
- Androgen-AR signaling enhances IGF1 signaling by increasing IGF1 receptor transcription in basal epithelial cells.
- Androgen-AR signaling increases IGF1 secretion by suppressing IGF-binding protein 3 in stromal cells.
- IGF1 signaling stimulates Wnt-β-catenin pathways in basal progenitors, promoting oncogenic transformation.
Conclusions:
- Cooperative, autocrine, and paracrine interactions between androgens and IGF1 drive prostate cancer.
- Targeting the interplay between androgen and IGF1 signaling presents novel therapeutic opportunities for prostate cancer.

01:19Interactions Between Signaling Pathways
6.2K
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...

03:03mTOR Signaling and Cancer Progression
3.8K
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.

01:24Regulation of Angiogenesis and Blood Supply
2.5K
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

01:22PI3K/mTOR/AKT Signaling Pathway
3.4K
The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast, mTORC2 consists of a...

01:16TGF - β Signaling Pathway
7.3K
The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors...

02:38Mitogens and the Cell Cycle
6.4K
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...
