Abstract:
In complicated disorders like cancer, signaling pathways form a tangled network. Targeting one gene may result in an unfavorable reaction from another off-target gene. Such entwined complexities may result in treatment resistance or failure in cancer patients. The PI3K/Akt/mTOR (phosphoinositol 3-kinase/protein kinase B/mammalian target of rapamycin) pathway is dysregulated in cervical cancer and is used as a biomarker for therapy. PI3K is a kinase that consists of a regulatory and catalytic domain and has phosphorylation capability. Class I components like the catalytic part (PIK3CA and PIK3CD) and regulatory part (like PIK3R1, PIK3R2, PIK3R3, and PIK3R5) are associated with oncogenesis and growth factors in cervical cancer. This review is aimed at discussing the involvement of the PI3K component of the PI3K/Akt/mTOR network in cervical cancer. Specifically, class I catalytic subunit PIK3CA has been identified as a pharmacological target, making it therapeutically significant. Apart from discussing the function of PI3K and PIK3CA in cervical cancer, we also discuss their inhibitors, which may be beneficial in treating cervical cancer.
Insights
The phosphoinositol 3-kinase (PI3K) pathway is crucial in cervical cancer. Targeting PI3K, especially PIK3CA, offers a promising therapeutic strategy for this complex disease.
Area of Science:
- Oncology
- Molecular Biology
- Biochemistry
Background:
- Signaling pathways in cancer are complex networks, often leading to treatment resistance.
- The phosphoinositol 3-kinase/Akt/mammalian target of rapamycin (PI3K/Akt/mTOR) pathway is frequently dysregulated in cervical cancer.
- PI3K, a key component, plays a role in oncogenesis and growth factor signaling within cervical cancer.
Purpose of the Study:
- To review the involvement of the PI3K pathway in cervical cancer.
