Recent advances in bioanalytical methods to measure proteome stability in cells

Area of Science:

• Biochemistry
• Molecular Biology
• Cell Biology

Background:

• Proteome stability is vital for protein homeostasis (proteostasis), ensuring proper protein conformation, activity, localization, and function.
• Stressors can disrupt proteostasis, leading to protein misfolding, aggregation, and cellular dysfunction.
• Protein unfolding and aggregation are linked to aging and diseases like neurodegenerative disorders, diabetes, and cancer.

Purpose of the Study:

• To review recent advancements in bioanalytical techniques for assessing proteome-wide protein stability.
• To provide insights into methodologies for monitoring cellular protein integrity.

Main Methods:

• Review of current literature on bioanalytical methods for protein stability assessment.
• Focus on techniques applicable to a proteome-wide scale within cellular contexts.

Main Results:

• Identification and summary of emerging bioanalytical strategies for measuring protein stability.
• Discussion of the utility of these methods in understanding proteostasis.

Conclusions:

• Accurate measurement of proteome stability is essential for elucidating biological processes and disease mechanisms.
• Advancements in bioanalytical methods offer powerful tools for studying protein homeostasis and its disruption.
