1. From the urine of rats, rabbits and humans treated with noscapine, two novel metabolites were isolated and identified as 7-hydroxy-6-methoxyphthalide (MA-1) and 6-hydroxy-7-methoxyphthalide (MA-2), mainly by mass spectrometry. 2. MA-2 (free and conjugated) amounted to 8.5% dose in rats (n=2) and 1.7% dose in rabbits (n=2) during the first 48 h. In(More)
Previously, we used the reverse transcription-polymerase chain reaction (RT-PCR) to show that mammaglobin (MGB1) can serve as a differential marker of breast cancer metastasis from primary lung cancer. However, mRNA-based methods are not appropriate for use in clinical practices. In this study, we examined MGB1 protein expression in 480 tumors from various(More)
Granulomatous lobular mastitis (GLM) is a rare inflammatory pseudotumor. No therapeutic modality for this disease has been established because of its rarity. The purpose of this study is to evaluate the treatment strategies of GLM. Twelve women who met the histological criteria for GLM were retrospectively studied. The clinical data and the presentation,(More)
The expressions of heparan sulfate glycosaminoglycans (HSGAGs) in breast carcinoma specimens from 60 patients were immunohistochemically investigated using monoclonal antibodies (mAbs) that recognized different epitopes of the glycan structure. Cytoplasmic expression of GlcA-GlcNH 3 + on HSGAG was detected in carcinomas at high frequency (58.3%) using mAb(More)
PI3K-Akt signaling is critical for the development, progression, and metastasis of malignant tumors, but its role in the tumor microenvironment has been relatively little studied. Here, we report that the Akt substrate Girdin, an actin-binding protein that regulates cell migration, is expressed and activated by Akt phosphorylation in cancer-associated(More)
BACKGROUND Evaluating circulating tumor cells (CTCs) is one way to predict outcome and monitor treatment in patients with MBC. In this prospective study, we evaluated CTCs in predicting treatment efficacy and overall survival (OS) using the CellSearch System (Veridex, LLC, Raritan, NJ). METHODS One hundred nineteen patients with MBC with measurable(More)
1. The metabolism of noscapine was studied in rabbits, rats and human. 2. Apart from the O-demethylated metabolites already reported, three metabolites were isolated and identified as meconine, cotarnine and hydrocotamine, respectively. 3. Mass fragmentography (chemical ionization) was used to determine these products simultaneously. 4. Meconine was the(More)
The possible association of high soy food consumption with low incidence of breast cancer in Asian countries has been widely investigated, but findings from epidemiologic studies have been inconsistent. Breast cancers defined by receptor status, estrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2) may have(More)
OBJECTIVE Although the fear of recurrence is a major concern among breast cancer survivors after their surgery, there are no instruments to evaluate their distress in Japan. This study examines the psychometric properties of the Japanese version of the concerns about recurrence scale, which was originally developed in the USA. METHODS The forward and(More)
We investigated the role of Nek2, a member of the serine-threonine kinase family, in the tumorigenic growth of breast carcinoma. Increased expression of Nek2 was observed in all breast carcinoma cell lines examined (BT20, BT474, Hs578T, MCF7, MDA-MB-231, T47D, and ZR-75-1) by immunoblotting. By treatment with Nek2 short interfering RNA (siRNA), expression(More)
