Molecular mechanisms of Nrf2‐mediated antioxidant response Tập 48 Số 2 - Trang 91-104 - 2009
Wenge Li, Ah‐Ng Tony Kong
AbstractNrf2 is the key transcription factor regulating the antioxidant response. Nrf2 signaling is repressed by Keap1 at basal condition and induced by oxidative stress. Keap1 is recently identified as a Cullin 3‐dependent substrate adaptor protein. A two‐sites binding “hinge & latch” model vividly depicts how Keap1 can efficiently present Nrf2 as substrate fo...... hiện toàn bộ Prostate cancer stem/progenitor cells: Identification, characterization, and implications Tập 46 Số 1 - Trang 1-14 - 2007

AbstractSeveral solid tumors have now been shown to contain stem cell‐like cells called cancer stem cells (CSC). These cells, although generally rare, appear to be highly tumorigenic and may be the cells that drive tumor formation, maintain tumor homeostasis, and mediate tumor metastasis. In this Perspective, we first provide our insight ...... hiện toàn bộ DNA methyltransferase and demethylase in human prostate cancer Tập 33 Số 3 - Trang 163-171 - 2002

AbstractRecent studies have shown that cytosine‐5 methylation at CpG islands in the regulatory sequence of a gene is one of the key mechanisms of inactivation. The enzymes responsible for CpG methylation are DNA methyltransferase (DNMT) 1, DNMT3a, and DNMT3b, and the enzyme responsible for demethylation is DNA demethylase (MBD2). Studies on methylation‐demethylatio...... hiện toàn bộ Peroxisome proliferator–activated receptor α in the human breast cancer cell lines MCF‐7 and MDA‐MB‐231 Tập 34 Số 4 - Trang 165-171 - 2002

AbstractPeroxisome proliferator–activated receptor (PPAR) α is a ligand‐activated transcription factor that has been linked with rodent hepatocarcinogenesis. It has been suggested that PPARα mRNA expression levels are an important determinant of rodent hepatic tumorigenicity. Previous work in rat mammary gland epithelial cells showed sign...... hiện toàn bộ
