Understanding Tamoxifen Resistance in Breast cancer

, 2016
Tamoxifen is the accepted therapy for patients with estrogen receptor α (ERα)−positive breast cancer. However, clinical resistance to tamoxifen, as demonstrated by recurrence or progression on therapy, is frequent and precedes death from metastases.

Targeting EPAS-1/HIF-2α Pathway to Address Endocrine Resistance in Luminal A Type Breast Cancer

Translational Oncology
Background: Tamoxifen is most often used as the first treatment for luminal A breast cancer; however, one-third of the patients are resistant to it. Numerous studies have shown that hypoxia contributes to drug resistance and is related to poor clinical ...

Norcantharidin regulates ERα signaling and tamoxifen resistance via targeting miR-873/CDK3 in breast cancer cells.

PLoS ONE, 2019
MiR-873/CDK3 has been shown to play a critical role in ERα signaling and tamoxifen resistance. Thus, targeting this pathway may be a potential therapeutic approach for the treatment of ER positive breast cancer especially tamoxifen resistant subtype ...

Targeting Pin1 by All-Trans Retinoic Acid (ATRA) Overcomes Tamoxifen Resistance in Breast Cancer via Multifactorial Mechanisms

Frontiers in Cell and Developmental Biology, 2019
Breast cancer is the most prevalent tumor in women worldwide and about 70% patients are estrogen receptor positive. In these cancer patients, resistance to the anticancer estrogen receptor antagonist tamoxifen emerges to be a major clinical obstacle ...

Clinical response after two cycles compared to HER2, Ki-67, p53, and bcl-2 in independently predicting a pathological complete response after preoperative chemotherapy in patients with operable carcinoma of the breast

, 2008
Introduction To investigate the predictive value of clinical and biological markers for a pathological complete remission after a preoperative dose-dense regimen of doxorubicin and docetaxel, with or without tamoxifen, in primary operable breast cancer ...

The role of human microbiota in breast cancer pathogenesis and treatment

iMeta, EarlyView.
The human microbiota contributes to breast cancer pathogenesis and treatment response through interactions involving the oral, gut, and breast microbial niches. (Left) Multi‐site dysbiosis is characterized by altered microbial composition and abundance across different anatomical sites.
