Insights

Nuclear receptor coactivators are essential for steroid hormone action. This review explores their mechanisms and crucial roles in reproductive physiology and brain development.

Area of Science:

  • Molecular Endocrinology
  • Neuroendocrinology
  • Reproductive Biology

Background:

  • Gonadal steroid hormones regulate gene expression impacting reproductive physiology and behavior.
  • Steroid hormone effects are mediated by intracellular receptors, part of the nuclear receptor superfamily.
  • Nuclear receptor coactivators are known to be crucial for efficient steroid receptor transcriptional activity in vitro.

Purpose of the Study:

  • To review the general mechanisms of nuclear receptor coactivators in steroid-dependent gene transcription.
  • To discuss recent findings on the function of these coactivators in reproductive physiology and behavior.
  • To highlight their roles in steroid-dependent brain development.

Main Methods:

  • Literature review of in vitro and in vivo studies.
  • Analysis of coactivator involvement in gene transcription.
  • Synthesis of current research on coactivator functions in reproductive tissues and the brain.

Main Results:

  • Nuclear receptor coactivators are widely distributed in steroid hormone-responsive tissues.
  • Emerging evidence demonstrates their critical roles in vivo, beyond in vitro observations.
  • Coactivators are integral to steroid-dependent processes in the brain, reproductive tract, and mammary gland.

Conclusions:

  • Nuclear receptor coactivators are vital for mediating steroid hormone actions.

Co-activators and Co-repressors

Gene transcription is regulated by the synergistic action of several proteins that form a complex at a gene regulatory site. This is observed in eukaryotes, where the regulation of gene expression is a complex process. Regulatory proteins in eukaryotes can broadly be classified into two types – regulators that bind directly to specific DNA sequences and co-regulators that associate with regulatory proteins but cannot directly bind to the DNA. These co-regulators are further divided into...

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:
RNA Polymerase II Accessory Proteins02:36

RNA Polymerase II Accessory Proteins

Proteins that regulate transcription can do so either via direct contact with RNA Polymerase or through indirect interactions facilitated by adaptors, mediators, histone-modifying proteins, and nucleosome remodelers. Direct interactions to activate transcription is seen in bacteria as well as in some eukaryotic genes. In these cases, upstream activation sequences are adjacent to the promoters, and the activator proteins interact directly with the transcriptional machinery. For example, in...
Regulation of Nuclear Protein Sorting01:45

Regulation of Nuclear Protein Sorting

Nuclear protein sorting regulates nucleus composition and gene expression, crucial for determining the fate of a eukaryotic cell. Hence, the entry and exit of molecules across the nuclear envelope is a tightly controlled process. Nuclear protein sorting can be inhibited by one of the following ways: 1) masking cargo signal sequences, 2) modifying the nuclear receptor's affinity for cargo, 3) controlling the nuclear pore size, 4) retaining the cargo during its transit to the cytosol or the...
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...
