Abstract

The histone lysine demethylase 3 A (KDM3A) is vital for the regulation of cancer physiology and pathophysiology. The purpose of this study was to investigate the effect of KDM3A expression with triple-negative breast cancer (TNBC) invasion and metastasis. In our results, knockout of KDM3A in TNBC MDA-MB-231 cells promoted apoptosis and inhibited the proliferation, invasion and metastasis of MDA-MB-231 cells. In addition, we found that in vivo experiments indicated that the growth, invasion and metastasis of metastatic neoplasms were significantly inhibited by knockout of KDM3A in a TNBC metastasis model. These findings suggest that KDM3A may be a potential therapeutic target for the treatment and prevention of TNBC, providing a critical theoretical basis for the effective prevention or treatment of breast cancer disease.

在 MDA-MB-231 乳腺癌细胞中敲除 KDM3A 可抑制肿瘤恶性程度并促进细胞凋亡
组蛋白赖氨酸去甲基化酶3 A(KDM3A)对癌症生理和病理生理学的调控至关重要。本研究旨在探讨 KDM3A 表达对三阴性乳腺癌(TNBC)侵袭和转移的影响。结果发现,在 TNBC MDA-MB-231 细胞中敲除 KDM3A 能促进细胞凋亡,抑制 MDA-MB-231 细胞的增殖、侵袭和转移。此外,我们发现体内实验表明,在 TNBC 转移模型中敲除 KDM3A 能显著抑制转移性肿瘤的生长、侵袭和转移。这些研究结果表明,KDM3A可能是治疗和预防TNBC的潜在治疗靶点,为有效预防或治疗乳腺癌疾病提供了重要的理论依据。

期刊介绍: The Journal of Molecular Histology publishes results of original research on the localization and expression of molecules in animal cells, tissues and organs. Coverage includes studies describing novel cellular or ultrastructural distributions of molecules which provide insight into biochemical or physiological function, development, histologic structure and disease processes. Major research themes of particular interest include: - Cell-Cell and Cell-Matrix Interactions; - Connective Tissues; - Development and Disease; - Neuroscience. Please note that the Journal of Molecular Histology does not consider manuscripts dealing with the application of immunological or other probes on non-standard laboratory animal models unless the results are clearly of significant and general biological importance. The Journal of Molecular Histology publishes full-length original research papers, review articles, short communications and letters to the editors. All manuscripts are typically reviewed by two independent referees. The Journal of Molecular Histology is a continuation of The Histochemical Journal.
