Key result
KCNK6 expression is significantly upregulated in breast cancer tissues compared to normal tissues, and its overexpression enhances breast cancer cell proliferation, invasion, and migration.
Why the study?
Identifying genes involved in breast cancer development is important for therapy targets, but the function of overexpressed KCNK6 in tumors had not been reported.
Does KCNK6 overexpression promote proliferation, invasion, and migration in breast cancer cells?
Does KCNK6 overexpression promote proliferation, invasion, and migration in breast cancer cells?

KCNK6 promotes breast cancer cell proliferation, invasion, and migration, suggesting it may serve as a potential molecular target for future breast cancer therapies.
KCNK6 overexpression may indicate a novel breast cancer target; hypothesis-generating and requires functional validation before clinical consideration.
Breast cancer is the most common malignant tumor in women, and its incidence is increasing each year. To effectively treat breast cancer, it is important to identify genes involved in its occurrence and development and to exploit them as potential drug therapy targets. Here, we found that potassium channel subfamily K member 6 (KCNK6) is significantly overexpressed in breast cancer, however, its function in tumors has not been reported. We further verified that KCNK6 expression is upregulated in breast cancer biopsies. Moreover, overexpressed KCNK6 was found to enhance the proliferation, invasion, and migration ability of breast cancer cells. These effects may occur by weakening cell adhesion and reducing cell hardness, thus affecting the malignant phenotype of breast cancer cells. Our study confirmed, for the first time, that increased KCNK6 expression in breast cancer cells may promote their proliferation, invasion, and migration. Moreover, considering that ion channels serve as therapeutic targets for many small molecular drugs in clinical treatment, targeting KCNK6 may represent a novel strategy for breast cancer therapies. Hence, the results of this study provide a theoretical basis for KCNK6 to become a potential molecular target for breast cancer treatment in the future.

Hou et al. (2021) studied Breast cancer (n=16). KCNK6 expression vs. Normal breast tissue was evaluated on KCNK6 protein expression in breast cancer tissues versus normal tissues (p=<0.0001). KCNK6 expression is significantly upregulated in breast cancer tissues compared to normal tissues, and its overexpression enhances breast cancer cell proliferation, invasion, and migration.
