Gene dosage imbalances: action, reaction, and models.

Area of Science:

• Genetics and Molecular Biology
• Cellular Biology
• Biochemistry

Background:

• Gene dosage alterations, including deletions, duplications, and aneuploidy, disrupt cellular stoichiometry.
• These imbalances can lead to the malfunction of macromolecular complexes and cellular networks.
• Such alterations are implicated in various inherited and somatic genetic disorders, such as Mendelian diseases, aneuploid syndromes, and cancer.

Purpose of the Study:

• To review the multifaceted effects of gene dosage alterations.
• To explore cellular responses aimed at counteracting these dosage imbalances.
• To examine biochemical models and therapeutic strategies for managing gene dosage issues.

Main Methods:

• Review of transcriptomic and proteomic data related to gene dosage alterations.
• Analysis of cellular responses to stoichiometric imbalances.
• Exploration of biochemical models for therapeutic intervention.

Main Results:

• Gene dosage alterations significantly impact transcriptomic and proteomic profiles.
• Cells exhibit diverse mechanisms to mitigate the consequences of gene dosage imbalances.
• Biochemical models offer insights into potential therapeutic targets.

Conclusions:

• Stoichiometric imbalances arising from gene dosage alterations are a key mechanism in genetic disorders.
• Cellular responses play a crucial role in maintaining homeostasis despite dosage perturbations.
• Targeting gene dosage modulation presents a promising avenue for treating genetic diseases.
