Expression of DDX49 in breast cancer and its mechanism regulating the proliferation and metastasis of breast cancer cells.
DEAD-box RNA helicase (DDX) is linked to the invasion, drug resistance, proliferation, and epithelial-mesenchymal transition of tumour cells. This study examined the potential mechanisms of DDX49 in breast cancer. The expression of DDX49 in breast cancer tissues and cells was evaluated. The effects of DDX49 on proliferation, invasion, migration and apoptosis of breast cancer cells were evaluated. The expression of proteins associated with the JAK/STAT pathway was examined. A xenograft tumour model was established. DDX49 expression is elevated in breast cancer tissues and cell lines. shDDX49 suppressed the ability of breast cancer cells to proliferate, invade, and migrate, but promoted apoptosis. Conversely, overexpression of DDX49 exerted an opposite effect. The activation of the JAK-STAT signalling pathway is inhibited by the shDDX49. shDDX49 efficiently inhibits tumour growth in mice with breast cancer. shDDX49 may hinder the growth and spread of breast cancer cells by inhibiting the JAK-STAT pathway.
期刊介绍：
Growth Factors is an international and interdisciplinary vehicle publishing new knowledge and findings on the regulators of cell proliferation, differentiation and survival. The Journal will publish research papers, short communications and reviews on current developments in cell biology, biochemistry, physiology or pharmacology of growth factors, cytokines or hormones which improve our understanding of biology or medicine. Among the various fields of study topics of particular interest include: •Stem cell biology •Growth factor physiology •Structure-activity relationships •Drug development studies •Clinical applications
