Insights

Liver X receptors (LXRs) are crucial for male reproduction, regulating functions in the testis, epididymis, and prostate. LXR deficiency significantly impacts male reproductive health, as shown by studies on LXR-deficient mice.

Area of Science:

  • Endocrinology
  • Molecular Biology
  • Reproductive Biology

Background:

  • Liver X receptors (LXRs) α and LXRβ are nuclear receptors.
  • Oxysterols, derived from cholesterol, are identified as natural LXR ligands.
  • LXRs are well-studied for lipid metabolism but also play vital roles in reproductive organs.

Purpose of the Study:

  • To review the impact of Liver X receptor (LXR) deficiency on male reproduction.
  • To highlight findings from phenotypic analyses of mice lacking LXRα, LXRβ, or both.

Main Methods:

  • Review of existing literature.
  • Phenotypic analysis of LXR-deficient mouse models (lxrα-/-, lxrβ-/-, and lxrα;β-/-).

Main Results:

  • LXR deficiency affects physiological functions in the testis, epididymis, and prostate.
  • Phenotypic analyses reveal specific roles of LXRα and LXRβ in male reproductive health.

Conclusions:

  • LXRs are essential regulators of male reproductive functions.
  • LXR-deficiency profoundly impacts male fertility and reproductive organ physiology.

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:
Intracellular Hormone Receptors01:08

Intracellular Hormone Receptors

Lipid-soluble hormones diffuse across the plasma and nuclear membrane of target cells to bind to their specific intracellular receptors. These receptors act as transcription factors that regulate gene expression and protein synthesis in the target cell
Liver Physiology01:30

Liver Physiology

The liver, an essential organ in the human body, performs over 200 vital functions that can be broadly categorized into metabolic, hematological, endocrine regulation, and bile production.
Metabolic Regulation:
The liver is the central organ involved in regulating blood composition. It stabilizes blood glucose levels, maintaining them within the range of  70–110 mg/dL. When these levels drop, the liver breaks down glycogen reserves and releases glucose into the bloodstream. It can also...
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.
Cholesterol: Significance and Regulation01:29

Cholesterol: Significance and Regulation

Although not a source of energy, cholesterol plays a significant role as a foundational structure for bile salts, steroid hormones, and vitamin D, as well as being a crucial component of plasma membranes. Approximately 15% of blood cholesterol is derived from our diet, with the remainder synthesized from acetyl CoA by the liver and intestines. Cholesterol is eliminated from the body through its conversion into bile salts, which are eventually discarded in the feces.
Considering cholesterol and...
Signal Transduction: Overview01:26

Signal Transduction: Overview

Cells respond to many types of information, often through receptor proteins positioned on the membrane. They respond to chemical signals, such as hormones, neurotransmitters, and other signaling molecules, initiating a series of molecular reactions to produce an appropriate response. This is called signal transduction. Cells also coordinate different responses elicited by the same signaling molecule via mediators, allowing molecular cross-talk.
Typically, signal transduction involves three...
