MARBP-lncRNA Complexes Alter Gene Function Through Modulation of Epigenetic Landscape.

Area of Science:

• Molecular Biology
• Epigenetics
• Genomics

Background:

• Eukaryotic chromatin is organized into functional domains by protein-DNA complexes.
• Scaffold/matrix attachment regions (S/MARs) anchor DNA elements to the nuclear matrix.
• Matrix-associated region binding proteins (MARBPs) interact with S/MARs to regulate gene expression.

Purpose of the Study:

• To elaborate on the regulatory crosstalk between lncRNAs and MARBPs.
• To discuss the implications of this crosstalk in human diseases.
• To explore potential therapeutic strategies targeting this interaction.

Main Methods:

• Review of existing literature on lncRNA-MARBP interactions.
• Analysis of epigenetic modifications mediated by MARBPs.
• Examination of disease mechanisms linked to MARBP and lncRNA dysregulation.

Main Results:

• MARBPs modulate the local epigenetic landscape via posttranslational modifications (PTMs) of DNA and histones.
• Crosstalk between lncRNAs and MARBPs governs epigenetic changes.
• Dysregulation of MARBPs or lncRNAs can alter gene expression, contributing to disease.

Conclusions:

• The lncRNA-MARBP regulatory network is crucial for maintaining cellular homeostasis.
• Aberrant lncRNA-MARBP interactions are implicated in various human diseases.
• Targeting the lncRNA-MARBP axis offers promising therapeutic avenues.
