Insights

Androgen receptors remain in prostate cancer even when resistant to androgens. This review covers how androgen receptor expression and function are regulated, offering insights into treatment strategies.

Area of Science:

  • Oncology
  • Molecular Biology
  • Biochemistry

Background:

  • Androgen receptor (AR) plays a critical role in prostate cancer development and progression.
  • Understanding AR regulation is crucial, as androgen-resistant prostate cancers still express AR.

Purpose of the Study:

  • To review recent findings on androgen receptor expression, structure, and function in prostate cancer.
  • To summarize the regulation of AR expression and function by various factors.
  • To discuss the role of AR-associated proteins in pathological conditions.

Main Methods:

  • Literature review of recent findings on androgen receptor.
  • Synthesis of information on AR regulation, function, and associated proteins.

Main Results:

  • Androgen receptor expression and function are regulated by androgens, growth factors, and protein kinase A activators.
  • Both wild-type and mutant AR functions are modulated by androgens and nonsteroidal activators.
  • AR activity influences the transcription of AR-regulated genes in a cell type-dependent manner.
  • AR-associated proteins, coactivators, and corepressors may play roles in prostate cancer pathology.

Conclusions:

  • Despite the development of androgen resistance, androgen receptors are present and actively involved in prostate cancer.
  • Further research into AR regulation and associated proteins may lead to novel therapeutic strategies for advanced prostate cancer.

Internal Receptors01:31

Internal Receptors

Many cellular signals are hydrophilic and therefore cannot pass through the plasma membrane. However, small or hydrophobic signaling molecules can cross the hydrophobic core of the plasma membrane and bind to internal, or intracellular, receptors that reside within the cell. Many mammalian steroid hormones use this mechanism of cell signaling, as does nitric oxide (NO) gas.
Mitogens and the Cell Cycle02:38

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...
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...
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.

Disorders of the Male Reproductive System

Men's health issues are increasingly recognized as significant, with several conditions posing common threats. Among these, testicular cancer is especially prevalent in younger men, particularly those aged 20 to 35 years. The disease often manifests as a painless mass in the testicles, sometimes accompanied by a sensation of heaviness or a dull ache.
Prostate disorders are another major concern. These conditions can impair urinary flow due to the prostate's location around the urethra. Symptoms...
