Abstract

Purpose

To explore the precise molecular by which CUEDC1, a 42 kDa protein containing a CUE domain located on chromosome 17q22, contributes to liver cancer metastasis.

Method

CUEDC1 protein expression levels were determined in liver cancer cells using Western blot analysis. The expression of CUEDC1 in these cells was silenced through siRNA transfection Cell viability was assessed using the Cell Counting Kit-8 (CCK-8) assay. Cell invasion and migration capabilities were evaluated using Transwell assays. The expression of transforming growth factor-beta (TGF-β)/ small mother against decapentaplegic (Smad) pathway, N-cadherin, alpha -smooth muscle actin (α-SMA), and E-cadherin was detected using Western blot.

Result

CUEDC1 expression was found to be elevated in liver cancer cells. Knockdown of CUEDC1 reduced the expression of TGF-β, p-Smad2, and p-Smad3, key components of the TGF-β/Smad pathway. Additionally, CUEDC1 knockdown significantly decreased cell survival, migration, invasion, and the EMT process in liver cancer cells.

Conclusion

CUEDC1 knockdown markedly reduces EMT and liver cancer cell metastasis by suppressing the TGF-β/Smad signaling pathway.

期刊介绍： Mutation Research (MR) provides a platform for publishing all aspects of DNA mutations and epimutations, from basic evolutionary aspects to translational applications in genetic and epigenetic diagnostics and therapy. Mutations are defined as all possible alterations in DNA sequence and sequence organization, from point mutations to genome structural variation, chromosomal aberrations and aneuploidy. Epimutations are defined as alterations in the epigenome, i.e., changes in DNA methylation, histone modification and small regulatory RNAs. MR publishes articles in the following areas: Of special interest are basic mechanisms through which DNA damage and mutations impact development and differentiation, stem cell biology and cell fate in general, including various forms of cell death and cellular senescence. The study of genome instability in human molecular epidemiology and in relation to complex phenotypes, such as human disease, is considered a growing area of importance. Mechanisms of (epi)mutation induction, for example, during DNA repair, replication or recombination; novel methods of (epi)mutation detection, with a focus on ultra-high-throughput sequencing. Landscape of somatic mutations and epimutations in cancer and aging. Role of de novo mutations in human disease and aging; mutations in population genomics. Interactions between mutations and epimutations. The role of epimutations in chromatin structure and function. Mitochondrial DNA mutations and their consequences in terms of human disease and aging. Novel ways to generate mutations and epimutations in cell lines and animal models.
