Summary
New research identifies RORγ as a promising target for castration-resistant prostate cancer. Inhibiting RORγ with small molecules effectively halts tumor growth in preclinical models.
Area of Science:
- Oncology
- Molecular Biology
- Endocrinology
Background:
- Castration-resistant prostate cancer (CRPC) remains a significant clinical challenge.
- Androgen receptor (AR) hyperactivity is a key driver of CRPC progression.
- RORγ, a nuclear receptor, is implicated in promoting AR hyperactivity in prostate cancer.
Discussion:
- This study investigates the role of RORγ in CRPC pathogenesis.
- RORγ's abundance in CRPC suggests it as a potential therapeutic target.
- Small-molecule antagonists of RORγ were synthesized and evaluated.
Key Insights:
- RORγ directly drives androgen receptor hyperactivity in castration-resistant prostate cancer.
- Blocking RORγ with small-molecule antagonists effectively suppresses AR signaling.
- Inhibition of RORγ impedes tumor growth in preclinical models of CRPC, including enzalutamide-resistant tumors.
Outlook:
- RORγ antagonists represent a novel therapeutic strategy for advanced prostate cancer.
- Further clinical investigation of RORγ inhibitors is warranted for CRPC treatment.
- Targeting RORγ may overcome resistance to current antiandrogen therapies.

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.

Genetic polymorphisms in drug targets have emerged as critical determinants of interindividual variability in drug response and toxicity. Pharmacogenomic investigations increasingly focus on identifying these variations to personalize and optimize therapeutic interventions. A drug target may be a receptor, enzyme, or signaling protein involved in pharmacologic responses or disease-related pathways. While early pharmacogenetic studies focused primarily on drug metabolism, current research...

4.8K
Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.

11.2K
Drugs target macromolecules to modify ongoing cellular processes. Primary drug targets include receptors, ion channels, transporters, and enzymes.
Receptors are either membrane-spanning or intracellular proteins, which upon binding a ligand, get activated and transmit the signal downstream to elicit a response. Drugs bind receptors, either mimicking the action of endogenous ligands or blocking the receptor activity to bring about a modified response. Nearly 35% of approved drugs target the G...

8.4K
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...
