ZNF643/ZFP69B Exerts Oncogenic Properties and Associates with Cell Adhesion and Immune Processes

Area of Science:

• Oncology
• Molecular Biology
• Genetics

Background:

• Global cancer burden necessitates understanding carcinogenesis molecular mechanisms.
• ZNF643/ZFP69B gene was previously found upregulated in multiple tumors.
• Its specific role in tumor biology requires investigation.

Purpose of the Study:

• To investigate the oncogenic properties of ZNF643.
• To correlate ZNF643 expression with clinicopathological parameters and patient survival.
• To elucidate the impact of ZNF643 on cancer cell phenotypes, adhesion, and immune signaling.

Main Methods:

• Utilized TCGA-centered databases for correlation analysis.
• Performed RNA-sequencing (RNA-seq) to assess gene expression changes upon ZNF643 silencing.
• Conducted in vitro studies for cancer cell phenotype assessment.
• Employed Chromatin immunoprecipitation sequencing (ChIP-seq) to identify ZNF643-bound genomic loci.

Main Results:

• ZNF643 levels were higher in most tumors than normal samples, potentially due to copy number variations.
• ZNF643 mRNA levels correlated with tumor stage, grade, patient survival, and molecular/immune subtypes.
• ZNF643 silencing deregulated genes involved in cancer growth, adhesion, and immune system processes.
• ZNF643 positively influenced cell cycle, migration, and invasion.
• ChIP-seq identified ZNF643-bound genes linked to adhesion and immune signaling.

Conclusions:

• ZNF643 exhibits oncogenic properties.
• ZNF643 significantly impacts cancer cell adhesion and immune processes.
• Findings provide insights into ZNF643's role in carcinogenesis, aiding in developing targeted therapies.
