Abstract

Insights

Liver X receptors (LXRs) are key targets in cancer therapy, modulating cell proliferation and apoptosis. Developing selective LXR ligands offers a promising strategy for treating various cancers, pending resolution of adverse effects.

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Oncology

Background:

  • Oxysterols, cholesterol derivatives, play roles in cellular processes.
  • Liver X receptors (LXRs) α and β regulate cell cycles in diverse cancer cell lines.
  • LXRs influence the balance between proliferation and apoptosis in various cancers.

Purpose of the Study:

  • To review the role of oxysterols and LXR ligands in cancer.
  • To explore the potential of LXR modulation as a cancer treatment strategy.

Main Methods:

  • Review of literature on oxysterols, cholesterol derivatives, and LXR ligands (agonists/antagonists).
  • Analysis of LXR activation effects on various tumor cell lines.
  • Identification of cancer types affected by LXR modulation.

Main Results:

  • LXR activation impacts a wide range of cancer cell lines.
  • Cancers such as prostate, breast, glioblastoma, colorectal, ovary, and leukemia are concerned.
  • Oxysterols and LXR ligands show potential in modulating cancer cell behavior.

Conclusions:

  • LXR ligand development is a novel and promising strategy for cancer therapy.
  • Adverse effects of LXR activation require further investigation before clinical application.
  • Future research focuses on engineering selective LXR modulators (SLiMs).

Targeted Cancer Therapies02:57

Targeted Cancer 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.
There are several types of targeted therapies against specific...

Transducer Mechanism: Nuclear Receptors01:31

Transducer Mechanism: Nuclear Receptors

Nuclear receptors, or NRs, are unique transcription factors that regulate gene transcription and affect the cellular pathways involved in reproduction, development, or metabolism. Their ability to be stimulated by small lipophilic ligands and control vital cellular processes makes them ideal drug targets. Nearly 10-15% of currently prescribed drugs target these receptors.
About 48 different soluble family members of nuclear receptors are identified that can be divided into two main classes:

Cancer Therapies

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

Transducer Mechanism: Enzyme-Linked Receptors01:27

Transducer Mechanism: Enzyme-Linked Receptors

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.
Major types that are helpful drug targets include:
