Dynamic Regulation of CYP19A1 Promoter Region under Control of CREB Family Members in Endometrial Tissues of Women with Endometriosis: A Case-Control Study

Summary

This summary is machine-generated.

Endometriosis involves increased expression of CREB, CREM, and CRTC2 genes. This, along with reduced ICER binding to the aromatase gene promoter, may drive the disease by affecting estrogen production.

Area Of Science

  • Reproductive endocrinology
  • Molecular biology
  • Genetics

Background

  • Endometriosis is an estrogen-dependent condition.
  • Cytochrome P450 aromatase (encoded by CYP19A1) is crucial for estrogen biosynthesis.
  • CREB, CREM, CRTC2, and ICER are key regulators of CYP19A1 expression.

Purpose Of The Study

  • To investigate the expression of CREB, CREM, and CRTC2 genes in endometriosis.
  • To analyze the binding of ICER to the CYP19A1 promoter II in endometriosis.

Main Methods

  • Case-control study design.
  • Quantitative gene expression analysis using real-time PCR.
  • Chromatin immunoprecipitation (ChIP) coupled with real-time PCR for protein-DNA interaction analysis.

Main Results

  • Significantly increased gene expression of CREB, CREM, and CRTC2 in ectopic endometrial lesions compared to controls.
  • Significantly decreased binding of ICER to CYP19A1 promoter II in both ectopic and eutopic endometriosis samples.

Conclusions

  • Overexpression of CREB, CREM, and CRTC2, along with reduced ICER binding, may contribute to endometriosis pathogenesis.
  • These molecular changes likely influence estrogen biosynthesis enzyme expression in endometriosis.

Master Transcription Regulators 02:23

6.8K

Master transcription regulators are regulatory proteins that are predominantly responsible for regulating the expression of multiple genes. Often these genes work in concert to drive a  complex process. Activation of a master transcription regulator can lead to a cascade of transcriptional activation necessary for that outcome. These regulators can directly bind to the regulatory sequences of the various genes involved, or they can indirectly regulate transcription by binding to regulatory...

Epigenetic Regulation 01:37

3.0K

Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

Cis-regulatory Sequences 02:02

9.6K

Cis-regulatory sequences are short fragments of non-coding DNA that are present on the same chromosomes as the genes that they regulate. These fragments serve as binding sites for transcriptional regulators, proteins that are responsible for controlling gene transcription and differential gene expression across cell types in eukaryotes. Cis-regulatory sequences can be close to the gene of interest or thousands of bases away in the DNA sequence; however, those sequences that are further away are...

Co-activators and Co-repressors 02:04

7.2K

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...

Hormonal Regulation of the Menstrual Cycle 01:22

206

The ovarian cycle regulates endometrial changes throughout a single menstrual cycle via the coordinated action of gonadotrophin-releasing hormone (GnRH) and gonadotrophins.
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...

Regulation of Expression at Multiple Steps 01:23

The gene expression in cells is regulated at different stages: (i) transcription, (ii) RNA processing, (iii) RNA localization, and (iv) translation. Transcriptional regulation is mediated by regulatory proteins such as transcription factors, activators, or repressors—these control gene expression by initiating or inhibiting the transcription of genes. Once a precursor or pre-mRNA is produced, it undergoes post-transcriptional modification, including 5' capping, splicing, and the...
