USP38: an important regulatory factor in tumor malignant progression.

Area of Science:

• Biochemistry
• Molecular Biology
• Oncology

Background:

• Ubiquitin-Specific Protease 38 (USP38) is a deubiquitinating enzyme (DUB) with known roles in cellular processes.
• Its function in cancer is complex and context-dependent, acting as both an oncogene and tumor suppressor.

Purpose of the Study:

• To review current research on USP38's structure, expression, and function in cancer.
• To elucidate USP38's mechanisms of action and its regulatory network.
• To discuss USP38's potential as a therapeutic target in malignancies.

Main Methods:

• Literature review of studies on USP38 in various cancer types.
• Analysis of USP38's structural characteristics and expression patterns.
• Examination of USP38's impact on cellular processes and signaling pathways.

Main Results:

• USP38 exhibits dual roles (oncogene/tumor suppressor) across different cancers.
• It regulates key proteins (e.g., HDAC1/3, KLF5, c-Myc) and pathways (e.g., JAK2/STAT3).
• USP38 influences proliferation, migration, invasion, and apoptosis.

Conclusions:

• USP38's multifaceted role in tumorigenesis is mediated by intricate interactions with its targets.
• USP38 presents a potential therapeutic target, but challenges in inhibitor development exist.
• Further research is needed to fully understand USP38's biology and clinical implications.
