MicroRNAs play pivotal roles in cancer stem cell regulation. Previous studies have shown that microRNA-34a (miR-34a) is downregulated in human breast cancer. However, it is unknown whether and how miR-34a regulates breast cancer stem cells. Notch signaling is one of the most important pathways in stem cell maintenance and function. In this study, we(More)
AlphaB-crystallin is known as a small heat shock protein with a cytoprotective function. This study was undertaken to investigate the relationship between alphaB-crystallin and changes seen in Alzheimer's disease. The distribution and immunohistochemical characteristics of alphaB-crystallin positive neurones in the cerebral cortices of 4 patients with(More)
Magnesium is an essential mineral for optimal metabolic function. Research has shown that the mineral content of magnesium in food sources is declining, and that magnesium depletion has been detected in persons with some chronic diseases. This has led to an increased awareness of proper magnesium intake and its potential therapeutic role in a number of(More)
OBJECTIVE We conducted a randomized, double-blind, placebo-controlled efficacy and tolerability trial of Matricaria recutita (chamomile) extract therapy in patients with mild to moderate generalized anxiety disorder (GAD). We hypothesized that chamomile would be superior to placebo in reducing GAD symptoms with a comparable tolerability profile. MATERIALS(More)
INTRODUCTION Aromatase inhibitor-associated arthralgia (AIAA) is a common and often debilitating symptom in breast cancer survivors. Since joint symptoms have been related to estrogen deprivation through the menopausal transition, we hypothesized that genetic polymorphisms in CYP19A1, the final enzyme in estrogen synthesis, may be associated with the(More)
Enforced expression of miR-34a eliminates cancer stem cells in some malignant tumors. Sirtuin-1 (SIRT1) is a direct target of miR-34a. Here we found low levels of miR-34a and high levels of SIRT1 in CD44+/CD24- breast cancer stem cells (BCSCs). MiR-34a overexpression and knockdown of SIRT1 decreased proportion of BSCSs and mammosphere formation. Expression(More)
The existence of breast cancer stem-like cells (BCSCs) has profound implications for cancer prevention. Genistein, a predominant isoflavone found in soy products, has multiple robust anti-tumor effects in various cancers, especially in the breast and prostate cancer. In this study, we aimed to evaluate genistein inhibition of BCSCs and its potential(More)
Premature discontinuation of aromatase inhibitors (AIs) in breast cancer survivors compromises treatment outcomes. We aimed to evaluate whether patient-reported joint pain predicts premature discontinuation of AIs. We conducted a retrospective cohort study of postmenopausal women with breast cancer on AIs who had completed a survey about their symptom(More)
The mechanisms of metastatic progression from hormonal therapy (HT) are largely unknown in luminal breast cancer. Here we demonstrate the enrichment of CD133(hi)/ER(lo) cancer cells in clinical specimens following neoadjuvant endocrine therapy and in HT refractory metastatic disease. We develop experimental models of metastatic luminal breast cancer and(More)
OBJECTIVE We conducted a randomized, double-blind, placebo-controlled, parallel group trial of the efficacy and tolerability of Cimicifuga racemosa (black cohosh) extract for the treatment of anxiety disorder due to menopause. We hypothesized that black cohosh would be superior to placebo in reducing anxiety symptoms of menopause, with a comparable(More)
