The natural antioxidant gallic acid (GA) was isolated from fruits of a medicinal Indonesian plant, Phaleria macrocarpa (Scheff.) Boerl. The structure was identified on the basis of spectroscopic analysis and comparison with authentic compound. GA demonstrated a significant inhibition of cell proliferation in a series of cancer cell lines and induced(More)
There is growing evidence that Rho proteins are deregulated by overexpression in tumours; and according to some reports, this correlates with disease progression. Our previous clinical study had demonstrated a correlation between RhoA expression and tumour progression in oesophageal squamous cell carcinoma (ESCC). These findings prompted us to study, using(More)
Paclitaxel, a potent anti-neoplastic agent, has been found to be effective against several tumours, including cervical cancer. However, the exact mechanism underlying the cytotoxic effects of pacitaxel, especially in the survival-signalling pathway, is poorly understood. The aim of this study was to investigate the molecular pathway of the cytotoxic effect(More)
Rho GTPases are involved in the organization of a microfilament network, cell-to-cell interaction, and malignant transformation. To elucidate the role of Rho GTPases in esophageal squamous cell carcinoma (ESCC), we compared the levels of RhoA and RhoC mRNA from ESCC with the corresponding normal tissue originating from the same patients. Real-time reverse(More)
The present study was designed to clarify the expression and prognostic significance of activated Akt and mTOR in cervical cancer and their correlation with response to neoadjuvant chemotherapy (NAC). Immunohistochemical analysis for p-Akt and p-mTOR expression was performed on paraffin-embedded biopsy specimens from 25 patients with advanced cervical(More)
The understanding of the cell signaling pathways and the molecular events leading to cell death of cancer cells will provide in-depth perspective into the identification and development of potent anticancer agents. A balance between cell proliferation and cell death has been raised as a rational target for the management of malignant tumors. In the present(More)
Alterations of the Akt/mTOR pathway have been observed in numerous types of cancer, thus this pathway represents an exciting new target for molecular therapeutics. We investigated the expression of activated Akt (p-Akt) and mTOR (p-mTOR) in patients with adenocarcinoma of the cervix and the involvement of the p-Akt/p-mTOR pathway in response to combination(More)
Clear cell adenocarcinoma of the ovary has a poor prognosis due to chemoresistance and early metastasis to the lymph nodes. It also can result in endometriosis and is the second most frequent type of ovarian cancer in Japan. Serous adenocarcinoma of the ovary is another common epithelial cancer tissue subtype in Japan, and it is highly sensitive to(More)
Purpose: Paclitaxel is a highly effective chemotherapy agent against adenocarcinomas and squamous cell carcinomas of the esophagus. However, its precise effects in human esophageal cancer cells are not well understood. This study was designed to examine the relationship between cell-cycle phases of paclitaxel-activated checkpoints and to elucidate the(More)
Tumor markers whose antigenic determinants have been demonstrated to consist of carbohydrates are probably one of the most extensive tools that have been used in routine cancer diagnosis. In this study, the relevance of carbohydrate antigen expression profile was examined in esophageal squamous cell carcinoma together with prognosis in 130 patients. The(More)
