Posttranslational modifications as therapeutic targets for intestinal disorders

Area of Science:

• Biochemistry
• Gastroenterology
• Molecular Biology

Background:

• Posttranslational modifications (PTMs) are crucial for regulating diverse physiological functions within the gastrointestinal tract.
• PTMs, including phosphorylation, ubiquitination, glycosylation, and proteolytic cleavage, play significant roles in maintaining gut health.
• Dysregulation of PTMs is implicated in the pathogenesis of various intestinal disorders.

Purpose of the Study:

• To review the implications of PTMs in major intestinal diseases.
• To highlight PTMs as potential biomarkers for differentiating pathological conditions.
• To explore pharmacological modulators of PTMs as therapeutic strategies.

Main Methods:

• Review of experimental evidence identifying PTM changes in patient samples, primary cells, and cell lines.
• Analysis of data from studies on inflammatory bowel disease, irritable bowel syndrome, celiac disease, and colorectal cancer.
• Synthesis of information on therapeutic applications of protein modification modulators.

Main Results:

• PTMs serve as common denominators and distinct biomarkers in various intestinal diseases.
• Specific PTM alterations are identified in patient-derived materials and cell models of intestinal disorders.
• Pharmacological modulation of protein modifications shows promise as a therapeutic avenue.

Conclusions:

• Understanding PTMs in intestinal diseases is vital for identifying novel biomarkers.
• Targeting PTMs offers potential for developing new therapeutic strategies for gut disorders.
• PTMs represent a critical area for future research in gastroenterology and molecular medicine.
