Summary
Phosphoinositides (PIs) are crucial for cell function, and their dysregulation causes disease. This review covers PI-metabolizing enzymes in cancer, leukemia, diabetes, genetic disorders, and bacterial infections.
Area of Science:
- Biochemistry
- Cell Biology
- Molecular Medicine
Background:
- Phosphoinositides (PIs) are vital lipids regulating numerous cellular processes.
- Strict control of intracellular PI levels is maintained by specific enzymes.
- Aberrant PI metabolism is linked to various human pathologies.
Purpose of the Study:
- To review human diseases associated with PI-metabolizing enzymes.
- To highlight the roles of specific enzymes like PTEN, SHIP phosphatases, myotubularins, and OCRL1 in disease.
- To explore bacterial manipulation of host PI metabolism during infection.
Main Methods:
- Literature review of scientific publications.
- Focus on PI-metabolizing enzymes and their associated human diseases.
- Examination of pathogenic bacterial strategies targeting host PI pathways.
Main Results:
- PTEN is implicated in cancer pathogenesis.
- SHIP phosphatases are linked to acute myeloid leukemia and diabetes.
- Myotubularin family members are involved in genetic diseases, and OCRL1 in Lowe syndrome.
- Bacterial pathogens utilize PI metabolism manipulation for infection.
Conclusions:
- Dysregulation of PI metabolism by specific enzymes is a significant factor in human disease.
- Targeting PI-metabolizing enzymes offers potential therapeutic strategies.
- Understanding PI metabolism is crucial for both human health and infectious disease research.
