Estrogen-induced mitochondrial reactive oxygen species as signal-transducing messengers.
We report here evidence in support of the role of 17beta-estradiol- (E2-) induced mitochondrial (mt) reactive oxygen species (ROS) as signal-transducing messengers. On the basis of monitoring theExpand

Chronic exposure to arsenic causes increased cell survival, DNA damage, and increased expression of mitochondrial transcription factor A (mtTFA) in human prostate epithelial cells.
Arsenic is a known carcinogen, and its exposure is associated with cancers in multiple target organs including the prostate. Whether arsenic causes cancer by increased cell proliferation or cellExpand

Chemotherapeutic Sensitization of Leptomycin B Resistant Lung Cancer Cells by Pretreatment with Doxorubicin
The development of novel targeted therapies has become an important research focus for lung cancer treatment. Our previous study has shown leptomycin B (LMB) significantly inhibited proliferation ofExpand

Simulated microgravity decreases DNA repair capacity and induces DNA damage in human lymphocytes
The effect of simulated microgravity on DNA damage and apoptosis is still controversial. The objective of this study was to test whether simulated microgravity conditions affect the expression ofExpand

Chronic Oxidative Stress Increases Growth and Tumorigenic Potential of MCF-7 Breast Cancer Cells
Accumulating evidence suggests that exposures to elevated levels of either endogenous estrogen or environmental estrogenic chemicals are associated with breast cancer development and progression.Expand

Identification of novel breast tumor-specific mutation(s) in the q11.2 region of chromosome 17 by RAPD/AP-PCR fingerprinting.
Analysis of genetic instability in breast cancer tissues compared to uninvolved breast tissues from the same individuals by RAPD (random amplified polymorphic DNA)/AP-PCR (arbitrarily primed PCR)Expand

Simulated microgravity‐induced epigenetic changes in human lymphocytes
Real space flight and modeled microgravity conditions result in changes in the expression of genes that control important cellular functions. However, the mechanisms for microgravity‐induced geneExpand

Estrogen-induced G1/S transition of G0-arrested estrogen-dependent breast cancer cells is regulated by mitochondrial oxidant signaling
We previously reported that 17-β-estradiol (E2)-induced mitochondrial reactive oxygen species (mtROS) act as signaling molecules. The purpose of this study was to investigate the effects ofExpand

Curcumin and Vitamin E Protect against Adverse Effects of Benzo[a]pyrene in Lung Epithelial Cells
Benzo[a]pyrene (BaP), a well-known environmental carcinogen, promotes oxidative stress and DNA damage. Curcumin and vitamin E (VE) have potent antioxidative activity that protects cells fromExpand

Reversal of epigenetic aberrations associated with the acquisition of doxorubicin resistance restores drug sensitivity in breast cancer cells
ABSTRACT Acquired resistance against doxorubicin is a major limitation in clinical treatment of breast cancer. The molecular mechanism behind the aberrant expression of genes leading to doxorubicinExpand
