ZBTB16 inhibits DNA replication and induces cell cycle arrest by targeting WDHD1 transcription in lung adenocarcinoma

Area of Science:

• Oncology
• Molecular Biology
• Genetics

Background:

• Lung adenocarcinoma is a major cause of cancer mortality.
• The role of ZBTB16 in lung adenocarcinoma pathophysiology remains unclear.
• ZBTB16 exhibits varied functions in different cancers.

Purpose of the Study:

• To elucidate the mechanism of ZBTB16 in lung adenocarcinoma.
• To investigate the correlation between ZBTB16 expression and patient survival.
• To identify potential therapeutic targets for lung adenocarcinoma.

Main Methods:

• Analysis of ZBTB16 mRNA, protein expression, and DNA methylation in lung adenocarcinoma tissues.
• Correlation analysis of ZBTB16 with clinical data and patient survival.
• In vitro studies using lung adenocarcinoma cell lines to assess ZBTB16 function.
• In vivo studies using xenograft mouse models.
• Identification and validation of ZBTB16 targets.

Main Results:

• ZBTB16 expression was decreased, while DNA methylation was increased in lung adenocarcinoma.
• Lower ZBTB16 levels correlated with poorer patient survival.
• Overexpression of ZBTB16 inhibited cell proliferation, invasion, migration, and induced cell cycle arrest, DNA damage, apoptosis, and mitotic catastrophe.
• ZBTB16 overexpression suppressed tumor growth in vivo.
• WDHD1 was identified as a key target gene, mediating ZBTB16's effects on proliferation and cell cycle.

Conclusions:

• ZBTB16 acts as a tumor suppressor in lung adenocarcinoma.
• ZBTB16 inhibits lung adenocarcinoma progression by downregulating WDHD1.
• ZBTB16 represents a potential novel therapeutic target for lung adenocarcinoma management.
