Recently, TWIST, a basic helix-loop-helix transcription factor, has been reported to play a key role in the metastatic progression of several types of human cancer. The aim of this study was to investigate the significance of TWIST expression in bladder cancer using tissue microassays generated from 226 bladder tissue specimens. Using immunohistochemical(More)
Recently, ID-1 (inhibitor of differentiation/DNA binding) is suggested as an oncogene and is reported to promote cell proliferation, invasion, and survival in several types of human cancer cells through multiple signaling pathways. However, how Id-1 interacts with these pathways and the immediate downstream effectors of the Id-1 protein are not known. In(More)
Paeoniae Radix (PR) is the root of traditional Chinese Herb named Paeonia lactiflora Pallas, which is commonly used to treat liver diseases in China for centuries. Several earlier studies have indicated that PR has anticancer growth activities, however the mechanism underlying these activities was unclear and remained to be elucidated. In this study, we(More)
TWIST, a basic helix-loop-helix transcription factor, has been reported to be associated with development and progression of human cancer. Recently, over expression of TWIST is found in cancer patients with shorter survival and poor response to chemotherapy. Previously, we found that upregulation of TWIST was responsible for the development of acquired(More)
Id-1 is a member of the HLH protein family that regulates a wide range of cellular processes such as cell proliferation, apoptosis, senescence and overexpression of Id-1 was recently suggested to play roles in the development and progression of different cancers. Previously, Id-1 was shown to physically interact with the viral protein E1A. Meanwhile, Id-1(More)
The presence of circulating tumor cells (CTC) is common in prostate cancer patients, however until recently their clinical significance was unknown. The CTC stage is essential for the formation of distant metastases, and their continuing presence after radical prostatectomy has been shown to predict recurrent or latent disease. Despite their mechanistic and(More)
MAD2 (mitotic arrest deficient 2) is a key regulator of mitosis. Recently, it had been suggested that MAD2-induced mitotic arrest mediates DNA damage response and that upregulation of MAD2 confers sensitivity to DNA-damaging anticancer drug-induced apoptosis. In this study, we report a potential novel role of MAD2 in mediating DNA nucleotide excision repair(More)
