Abstract
BACKGROUND

The role of Sm-like 5 (LSM5) in colon cancer has not been determined. In this study, we investigated the role of LSM5 in progression of colon cancer and the potential underlying mechanism involved.

AIM

To determine the role of LSM5 in the progression of colon cancer and the potential underlying mechanism involved.

METHODS

The Gene Expression Profiling Interactive Analysis database and the Human Protein Atlas website were used for LSM5 expression analysis and prognosis analysis. Real-time quantitative polymerase chain reaction and Western blotting were utilized to detect the expression of mRNAs and proteins. A lentivirus targeting LSM5 was constructed and transfected into colon cancer cells to silence LSM5 expression. Proliferation and apoptosis assays were also conducted to evaluate the growth of the colon cancer cells. Human GeneChip assay and bioinformatics analysis were performed to identify the potential underlying mechanism of LSM5 in colon cancer.

RESULTS

LSM5 was highly expressed in tumor tissue and colon cancer cells. A high expression level of LSM5 was related to poor prognosis in patients with colon cancer. Knockdown of LSM5 suppressed proliferation and promoted apoptosis in colon cancer cells. Silencing of LSM5 also facilitates the expression of p53, cyclin-dependent kinase inhibitor 1A (CDKN1A) and tumor necrosis factor receptor superfamily 10B (TNFRSF10B). The inhibitory effect of LSM5 knockdown on the growth of colon cancer cells was associated with the upregulation of p53, CDKN1A and TNFRSF10B.

CONCLUSION

LSM5 knockdown inhibited the proliferation and facilitated the apoptosis of colon cancer cells by upregulating p53, CDKN1A and TNFRSF10B.

Keywords: Sm-like 5, Colon cancer, Proliferation, Apoptosis, Knockdown

Core Tip: Sm-like 5 (LSM5) was highly expressed in tumor tissue and cells of colon cancer. Our study indicated that knockdown of LSM5 had an anti-tumor effect in colon cancer by up-regulating p53, cyclin-dependent kinase inhibitor 1A and tumor necrosis factor receptor superfamily 10B, which providing an important insight on the role of LSM5 in colon cancer development.
