GABRD as an Emerging Oncogene: Exploring Functions and Therapeutic Implications Across Cancers

Area of Science:

• Neuroscience and Oncology
• Molecular Biology and Cancer Research

Background:

• Gamma-aminobutyric acid type A receptor subunit delta (GABRD) is a key inhibitory neurotransmitter receptor in the brain.
• Aberrant GABRD expression is observed in various non-neural cancers, including breast, colorectal, and gastric cancers.
• GABRD plays a complex and paradoxical role in oncogenesis.

Purpose of the Study:

• To review the biological characteristics of GABRD and its role in cancer pathophysiology.
• To explore GABRD's involvement in cancer cell proliferation, invasion, and metastasis.
• To analyze GABRD's interactions with the tumor microenvironment and its diverse mechanisms across cancer types.

Main Methods:

• Literature review synthesizing current research on GABRD in non-neural malignancies.
• Analysis of downstream signaling pathways activated by GABRD.
• Examination of GABRD's role in the tumor microenvironment and its varied functions in different cancers.

Main Results:

• GABRD activation initiates signaling pathways promoting cancer cell proliferation, invasion, and metastasis.
• GABRD interacts with the tumor microenvironment, influencing cancer progression.
• GABRD exhibits diverse oncogenic functions and mechanisms across various cancer types.

Conclusions:

• GABRD is implicated in promoting cancer progression through specific signaling pathways.
• GABRD presents a potential novel therapeutic target for cancer intervention.
• Further research is needed to overcome challenges and fully exploit GABRD's therapeutic potential.
