Expression of Phosphoinositide-specific Phospholipase C enzymes in normal endometrium and in endometriosis

The different expression of PI-PLC enzymes in the endometrium and endometriosis tissue suggests the hypothesis that PI-PLC enzymes, main effectors in PI signaling, might be involved in the pathogenesis of endometriosis.

Abstract

Objective:

To delineate the panel of expression of phosphoinositide-specific phospholipase C (PI-PLC) signaling enzymes in normal endometrium and in endometriosis.

Design:

Clinical/experimental study.

Setting:

University.

Patient(s):

Healthy donor woman and endometriosis-affected woman.

Intervention(s):

Normal endometrium and endometriosis surgical biopsies were analyzed using gene expression analyses methodology (reverse transcriptase-polymerase chain reaction [PCR], bioanalyses).

Main Outcome Measure(s):

Gene expression (messenger RNA concentration) measures of 12 PI-PLC enzymes: PI-PLC β1, PI-PLC β2, PI-PLC β3, PI-PLC β4, PI-PLC γ1, PI-PLC γ2, PI-PLC δ1, PI-PLC δ3, PI-PLC δ4, PI-PLC ε, PI-PLC η1, and PI-PLC η2.

Result(s):

PI-PLC β1, PI-PLC β3, PI-PLC δ1, and PI-PLC δ3 enzymes were detected, although differently expressed in normal and endometriosis tissues.

Conclusion(s):

The involvement of PI-PLC enzymes in inflammation and the consistency of susceptible endometriosis loci with PI-PLC genes mapping corroborate the hypothesis that PI signaling might be involved in the pathogenesis of endometriosis.
