Abstract
Background: STAM-binding protein-like 1 (STAMBPL1) functions as a deubiquitinase to cleave Lys63 ubiquitin linkage, and is associated with cancer dissemination and progression. The role of STAMBPL1 in colorectal cancer (CRC) remains unclear.
Methods: STAMBPL1 expression was determined by western blot and qRT-PCR. Cell proliferation was detected by colony formation and MTT assays, and apoptosis was assessed by flow cytometry. The metastasis was evaluated by transwell and wound healing assays. An animal xenograft experiment was used to investigate the effect of STAMBPL1 on tumor growth.
Results: The expression of STAMBPL1 was elevated in CRC cells. Knockdown of STAMBPL1 reduced cell viability of CRC and suppressed the proliferation, invasion, and migration. Apoptosis of CRC was induced by silence of STAMBPL1. Tumor growth of CRC was also suppressed by the silence of STAMBPL1. Knockdown of STAMBPL1 increased IκB and decreased phosphorylation of IκB to reduce p65 phosphorylation.
Conclusion: Knockdown of STAMBPL1 inhibited cell growth and metastasis of CRC through inactivation of the NF-κB pathway.
期刊介绍：
Protein & Peptide Letters publishes letters, original research papers, mini-reviews and guest edited issues in all important aspects of protein and peptide research, including structural studies, advances in recombinant expression, function, synthesis, enzymology, immunology, molecular modeling, and drug design. Manuscripts must have a significant element of novelty, timeliness and urgency that merit rapid publication. Reports of crystallization and preliminary structure determination of biologically important proteins are considered only if they include significant new approaches or deal with proteins of immediate importance, and preliminary structure determinations of biologically important proteins. Purely theoretical/review papers should provide new insight into the principles of protein/peptide structure and function. Manuscripts describing computational work should include some experimental data to provide confirmation of the results of calculations.
Protein & Peptide Letters focuses on:
Structure Studies
Advances in Recombinant Expression
Drug Design
Chemical Synthesis
Function
Pharmacology
Enzymology
Conformational Analysis
Immunology
Biotechnology
Protein Engineering
Protein Folding
Sequencing
Molecular Recognition
Purification and Analysis
