NGAL as a Potential Target in Tumor Microenvironment

Area of Science:

• Oncology
• Molecular Biology
• Cancer Research

Background:

• Tumor microenvironment communication between cancer and stromal cells dictates tumor progression.
• Current immunotherapies like checkpoint inhibitors and CAR-T are effective but limited, especially for solid tumors.
• Novel molecular targets within the tumor secretome are needed to enhance anti-cancer strategies.

Purpose of the Study:

• To review the multifaceted roles of Neutrophil Gelatinase-Associated Lipocalin (NGAL) within the tumor microenvironment.
• To explore NGAL's involvement in cancer senescence-associated secretory phenotype (SASP).
• To identify potentially targetable functions of NGAL for future cancer therapies.

Main Methods:

• Literature review focusing on NGAL's function in tumor biology.
• Analysis of NGAL's role in cancer-stromal cell cross-talk.
• Examination of NGAL's contribution to SASP.

Main Results:

• NGAL is abundantly secreted by various human tumors.
• NGAL plays significant roles within cancer cells, stromal cells, and their interactions.
• NGAL is implicated in the complex processes of cancer senescence.

Conclusions:

• NGAL is a promising therapeutic target due to its diverse functions in the tumor microenvironment.
• Understanding NGAL's roles in SASP and cell signaling could lead to new treatment avenues.
• Targeting NGAL may help overcome therapeutic resistance in solid tumors.
