Breast cancer stem cells (BCSCs) have high tumorigenicity and invasiveness, which contributes to recurrence and metastasis. The long non‐coding RNA SOX21‐AS1 has been previously reported to modulate the properties of breast cancer stem cells via targeting SOX2, although the underlying molecular mechanisms remain unclear. To investigate this issue, ...

To investigate whether carbon-ion beam alone, or in combination with lapatinib, has a beneficial effect in targeting HER2-positive breast cancer stem-like cells (CSCs) compared to that of X-rays, human breast CSCs derived from BT474 and SKBR3 cell lines were treated with a carbon-ion beam or X-rays irradiation alone or in combination with lapatinib...

Breast Cancer stem cells (BCSCs) have been extensively studied and have been used directly as a therapeutic target, but how the BCSCs themselves are regulated remain unclear. Here we reported identification of miR-205 that may act as a tumor suppressor and negatively-regulate BCSCs stemness and tumor malignance. By qRT-PCR analysis, we have shown t...

Runx2, a master regulator of osteogenesis, is abnormally expressed in advanced breast cancer. Here we addressed Runx2 contribution to breast cancer cell growth and metastasis. We found that CD44 and Runx2 were both elevated in breast cancer tissues compared with the adjacent normal tissues in breast cancer patients. Runx2 expression was significant...

Breast cancer stem cells (BCSCs) are the minor population of breast cancer (BC) cells that exhibit several phenotypes such as migration, invasion, self-renewal, and chemotherapy as well as radiotherapy resistance. Recently, BCSCs have been more considerable due to their capacity for recurrence of tumors after treatment. Recognition of signaling pat...

Breast cancer is one of the most common life-threatening malignancies and the top cause of cancer deaths in women. Although many conventional therapies exist for its treatment, breast cancer still has many handicaps to overcome. Cancer stem cells (CSCs) are a well-known cause of tumor recurrences due to the ability of CSCs for self-renewal and diff...
G protein-coupled estrogen receptor-1 (GPER), a member of the G protein-coupled receptor (GPCR) superfamily, mediates estrogen-induced proliferation of normal and malignant breast epithelial cells. However, its role in breast cancer stem cells (BCSCs) remains unclear. Here we showed greater expression of GPER in BCSCs than non-BCSCs of three patien...

Histone demethylase KDM7A regulates neuronal differentiation and development in mammals. In this study, we found that KDM7A was also required for breast cancer stem cells (BCSCs) maintenance. Silencing KDM7A significantly reduced the BCSCs population and mamosphere formation in vitro, and inhibited breast tumor growth in vivo. Restoring KDM7A expre...

Triple-negative breast cancer (TNBC) is a subtype of breast cancer characterized by the absence of estrogen and progesterone receptors (ER, PR) and lacking an overexpression of human epidermal growth factor receptor 2 (HER2). Apart from this lack of therapeutic targets, TNBC also shows an increased capacity for early metastasis and therapy resistan...

Metformin (MET) is an anti-diabetic drug effective against breast cancer, targeting breast cancer stem cells (BCSCs). MET-encapsulating liposome (LP-MET) and Herceptin-conjugated LP-MET (Her-LP-MET) were evaluated for their anti-cancer effect in vitro and in vivo. Size and zeta potentials of LP-MET and Her-LP-MET were suitable for enhanced permeabi...
