BACKGROUND Several treatment alternatives are available for primary breast cancer, although those for metastatic disease or inflammation associated with tumor progression are ineffective. Therefore, there is a great need for new therapeutic alternatives capable of generating an immune response against residual tumor cells, thus contributing to eradication of micrometastases and cancer stem cell...

BACKGROUND AZD4547, a small-molecule inhibitor targeting the tyrosine kinase of Fibroblast Growth Factor Receptors (FGFRs), is currently under phase II clinical study for human subjects having breast cancer, while the underlying mechanism remains elusive. The aim of this study is to explore the potential mechanism by which AZD4547 inhibits breast tumor lung metastases at the level of the tumor ...

The mouse breast cancer cell lines 4T1, 4T07, and 67NR are highly tumorigenic but vary in metastatic potential: 4T1 widely disseminates, resulting in secondary tumors in the lung, liver, bone, and brain; 4T07 spreads to the lung and liver but is unable to establish metastatic nodules; 67NR is unable to metastasize. The Bcl-2/adenovirus E1B 19 kDa interacting protein-3 (Bnip-3) was recently show...

Chemotherapy-induced peripheral neuropathy is a major dose-limiting side effect of commonly used chemotherapeutic agents. However, there are no effective strategies to treat the neuropathy. We examined whether Goshajinkigan, a herbal medicine, would prevent paclitaxel-induced allodynia without affecting the anticancer action in mice. Murine breast cancer 4T1 cells were inoculated into the mamma...

BACKGROUND The development of metastases involves the dissociation of cells from the primary tumor to penetrate the basement membrane, invade and then exit the vasculature to seed, and colonize distant tissues. The last step, establishment of macroscopic tumors at distant sites, is the least well understood. Four isogenic mouse breast cancer cell lines (67NR, 168FARN, 4TO7, and 4T1) that differ...

Breast cancer is the most common malignant tumor in women and a big challenge to clinical treatment due high morbidity mortality. The pH/ROS dual-responsive nanoplatforms may be an effective way significantly improve therapeutic efficacy of breast cancer. Herein, we report docetaxel (DTX)-loaded pH/ROS-responsive NP that could achieve active targeting cells selective complete drug release for d...

Objective(s): Breast cancer is one of the most common cancers in the world and is on the increase. MUC1 and HER2 as tumor-associated antigens (TAAs) are abnormally expressed to some extent in 75–80% of breast cancers.  In our present research, a novel chimeric MUC1-HER2 (HM) protein was designed and used to study whether an immune response can be generated against these TAAs. In vitro analysis ...

Twist1 is a transcription factor driving epithelial-mesenchymal transition, invasion and metastasis of breast cancer cells. Mice with germ-line Twist1 knockout are embryonic lethal, while adult mice with inducible Twist1 knockout have no obvious health problems, suggesting that Twist1 is a viable therapeutic target for the inhibition of invasion and metastasis of breast cancer in adult patients...

Interleukin-13 Receptor alpha 2 (IL-13Ra2) is a tumor antigen and a potent target for cancer therapy. Previously, we have reported that histone deacetylase (HDAC) inhibitors upregulated the IL-13Ra2 expression and enhanced anti-cancer effects of IL-13-PE, an immunotoxin composed of interleukin-13 and truncated Pseudomonas exotoxin, in a mouse model of human pancreatic cancer. Herein, we have in...
