Implication

Narrative review reveals distinct and coordinated functions of PGHS-1 and PGHS-2 isozymes, indicating independent prostanoid biosynthetic pathways.

Key Points

To review the distinct, overlapping, and compensatory physiological functions and biochemical pathways of the two cyclooxygenase isoforms, PGHS-1 and PGHS-2.
Synthesized findings from PGHS-1-deficient and PGHS-2-deficient knockout mouse models.
Evaluated physiological and biochemical data utilizing isoform-specific inhibitors and prostanoid biosynthetic analyses.
PGHS-1 uniquely drives baseline processes like platelet aggregation, whereas PGHS-2 is specifically required for specialized events such as ovulation.
Both isozymes function coordinately in inflammation and carcinogenesis, and can mutually compensate during parturition and ductus arteriosus remodeling.
Biochemical characterization confirms that PGHS-1 and PGHS-2 operate through distinct, independent prostanoid biosynthetic pathways.
