Abstract:
Endometriosis is an estrogen-dependent disorder characterized by ectopic growth of endometrial tissue. There is a lack of effective biomarkers for early detection and revealing mechanisms of endometriosis. CSNK2A1 is a compositionally active serine/threonine protein kinase that exerts its role by phosphorylating a variety of substrates, however, the role and mechanism of CSNK2A1 in endometriosis progression is still unclear. The aim of this study was to uncover the role of CSNK2A1 in endometriosis and elucidate the relevant mechanisms. Herein, we found CSNK2A1 is highly expressed in endometriosis. Its depletion inhibited the activity of ectopic endometrial stromal (ESC) cells. Further, knocking down of CSNK2A1 restrained the motility of ESC cells, and its ablation contributed to the autophagy of ESC cells. Mechanically, the depletion of CSNK2A1 blocked the PI3K/Akt/mTOR pathway in ESC cells. In summary, CSNK2A ablation inhibited the viability, autophagy, proliferation and invasion of ectopic endometrial stromal cells via targeting PI3K/Akt/mTOR pathway.
Insights
Targeting CSNK2A1 kinase in endometriosis inhibits cancer cell viability, proliferation, and invasion. This study reveals CSNK2A1 as a potential therapeutic target for endometriosis progression.
Area of Science:
- Gynecology
- Molecular Biology
- Cell Biology
Background:
- Endometriosis is an estrogen-dependent disorder with ectopic endometrial tissue growth.
- Current diagnostic biomarkers for early detection and mechanistic insights into endometriosis are lacking.
- The role of CSNK2A1 (Casein Kinase 2 Alpha 1) in endometriosis progression remains unclear.
Purpose of the Study:
- To investigate the role and underlying mechanisms of CSNK2A1 in endometriosis.
- To determine if CSNK2A1 is a potential therapeutic target for endometriosis.
Main Methods:

- In vitro studies involving knockdown of CSNK2A1 in ectopic endometrial stromal (ESC) cells.
- Assessment of ESC cell viability, motility, proliferation, invasion, and autophagy.
- Investigation of the PI3K/Akt/mTOR signaling pathway.
Main Results:
- CSNK2A1 expression is significantly elevated in endometriosis.
- Depletion of CSNK2A1 inhibited ESC cell viability, proliferation, and invasion.
- Knockdown of CSNK2A1 reduced ESC cell motility and promoted autophagy.
- CSNK2A1 ablation blocked the PI3K/Akt/mTOR signaling pathway in ESC cells.
Conclusions:
- CSNK2A1 plays a crucial role in the progression of endometriosis.
- Ablation of CSNK2A1 inhibits key cellular processes in ectopic endometrial stromal cells.
- Targeting CSNK2A1 and the PI3K/Akt/mTOR pathway presents a potential therapeutic strategy for endometriosis.
