Chitinase-3 like-protein-1 (YKL-40) Promotes Anorectal Mucosal Melanoma Progression via the PI3K-AKT Signaling Pathway.
Objective: Anorectal mucosal melanoma is a rare and aggressive cancer with limited treatment options. Investigating specific molecular pathways may provide insight into the development and progression of this cancer. This study aims to investigate the role of chitinase-3-like protein-1 (YKL-40) in promoting the development of anorectal mucosal melanoma through the PI3K-AKT signaling pathway.
Methods: Perianal cells from healthy volunteers and melanoma cells from patients with early, middle and advanced anorectal melanoma were obtained. Western blotting was performed to detect the protein expression of PI3K, AKT, and the downstream proteins mTOR, p-mTOR, ERK, and p-ERK, respectively. Subsequently, we constructed knockout and overexpression of YKL-40 melanoma cell lines, then used western blot assay to test for YKL-40, PI3K and AKT protein expression.
Results: A significant increase in the expression of PI3K, AKT, and the downstream proteins mTOR, pmTOR, ERK, and pERK was observed in melanoma cells, and the expression of these proteins increased with the development of melanoma. After YKL-40 was knocked out, PI3K and AKT expression decreased in melanoma cells in patients with advanced melanoma. On the contrary, PI3K and AKT protein expression increased significantly after YKL-40 overexpression.
Conclusion: There is a positive correlation between the expression levels of PI3K, AKT, mTOR, p-mTOR, ERK, and p-ERK and the stage of tumor development. The PI3K-AKT signaling pathway promotes the progress of anorectal mucosal melanoma. Chitinase-3-like protein-1 (YKL-40) regulates the progression of anorectal mucosal melanoma through the PI3K-AKT signaling pathway. Investigating specific molecular pathways may provide a better understanding of anorectal mucosal melanoma. The findings from this study could contribute to the development of new diagnosis and treatment strategies for this rare and aggressive cancer. Future research directions may include investigating other possible pathways involved in melanoma progression.
期刊介绍：
Launched in 1995, Alternative Therapies in Health and Medicine has a mission to promote the art and science of integrative medicine and a responsibility to improve public health. We strive to maintain the highest standards of ethical medical journalism independent of special interests that is timely, accurate, and a pleasure to read. We publish original, peer-reviewed scientific articles that provide health care providers with continuing education to promote health, prevent illness, and treat disease. Alternative Therapies in Health and Medicine was the first journal in this field to be indexed in the National Library of Medicine. In 2006, 2007, and 2008, ATHM had the highest impact factor ranking of any independently published peer-reviewed CAM journal in the United States—meaning that its research articles were cited more frequently than any other journal’s in the field.
Alternative Therapies in Health and Medicine does not endorse any particular system or method but promotes the evaluation and appropriate use of all effective therapeutic approaches. Each issue contains a variety of disciplined inquiry methods, from case reports to original scientific research to systematic reviews. The editors encourage the integration of evidence-based emerging therapies with conventional medical practices by licensed health care providers in a way that promotes a comprehensive approach to health care that is focused on wellness, prevention, and healing. Alternative Therapies in Health and Medicine hopes to inform all licensed health care practitioners about developments in fields other than their own and to foster an ongoing debate about the scientific, clinical, historical, legal, political, and cultural issues that affect all of health care.
