Insights

Prostate cancer treatments targeting the androgen receptor (AR) face resistance. Epigenetic enzymes, like HDAC6, stabilize AR, offering new therapeutic targets to overcome castration-resistant prostate cancer.

Area of Science:

  • Oncology
  • Molecular Biology
  • Epigenetics

Background:

  • Prostate cancer is a leading cause of cancer death in men.
  • The androgen receptor (AR) is a key therapeutic target.
  • Resistance to androgen deprivation therapy (ADT) leads to castration-resistant prostate cancer (CRPC).

Purpose of the Study:

  • To summarize recent findings on the role of epigenetic enzymes in AR signaling.
  • To highlight how targeting epigenetic enzymes may overcome resistance to ADT.

Main Methods:

  • Review of current literature on epigenetic enzymes and AR signaling in prostate cancer.
  • Focus on histone-modifying enzymes, including HDAC6, and their role in AR stabilization.

Main Results:

  • Epigenetic events facilitate AR signaling in prostate cancer.
  • Enzymes like HDAC6 stabilize AR, contributing to CRPC.
  • Interdiction of epigenetic enzymes shows potential to attenuate AR action.

Conclusions:

  • Epigenetic enzymes are critical regulators of AR signaling in prostate cancer.
  • Targeting epigenetic enzymes represents a promising strategy to overcome treatment resistance in CRPC.

Epigenetic Regulation01:37

Epigenetic Regulation

Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

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.

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...
Receptor Downregulation in MVBs01:15

Receptor Downregulation in MVBs

Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that  lead to cell proliferation, migration, and differentiation. Overexpression of EGFR  stimulates cells to proliferate. Excessive  EGFR activation may...
