Journal ArticleDOI
Ovarian dysfunction and gene-expressed characteristics of female mice caused by long-term exposure to titanium dioxide nanoparticles.
Guodong Gao,Yuguan Ze,Bing Li,Xiaoyang Zhao,Ting Zhang,Lei Sheng,Ringhu Hu,Suxin Gui,Xuezi Sang,Qingqing Sun,Jie Cheng,Zhe Cheng,Ling Wang,Meng Tang,Fashui Hong +14 more
TL;DR: The apparent regulation of key ovarian genes supports the hypothesis that TiO(2) NPs directly affects ovarian function, which can accumulate in the ovary and result in ovarian damage, cause an imbalance of mineral element distribution and sex hormones, decrease fertility or the pregnancy rate and oxidative stress in mice.
Journal ArticleDOI
Molecular mechanism of kidney injury of mice caused by exposure to titanium dioxide nanoparticles.
Suxing Gui,Zengli Zhang,Lei Zheng,Yaling Cui,Xiaorun Liu,Na Li,Xuezi Sang,Qingqing Sun,Guodong Gao,Zhe Cheng,Jie Cheng,Ling Wang,Meng Tang,Fashui Hong +13 more
TL;DR: Findings implied that TiO(2) NPs-induced nephric injury of mice might be associated with alteration of inflammatory cytokine expression and reduction of detoxification of TiO (2)NPs.
Journal ArticleDOI
Titanium dioxide nanoparticle-induced testicular damage, spermatogenesis suppression, and gene expression alterations in male mice.
Guodong Gao,Yuguan Ze,Xiaoyang Zhao,Xuezi Sang,Lei Zheng,Xiao Ze,Suxin Gui,Lei Sheng,Qingqing Sun,Jie Hong,Xiaohong Yu,Ling Wang,Fashui Hong,Xueguang Zhang +13 more
TL;DR: It is shown that TiO2 NPs can cross the blood-testis barrier to reach the testis and accumulate therein, which, in turn, results in testicular lesions, sperm malformations, and alterations in serum sex hormone levels.
Journal ArticleDOI
Neurotoxicity and gene-expressed profile in brain-injured mice caused by exposure to titanium dioxide nanoparticles
Yuguan Ze,Renping Hu,Xiaochun Wang,Xuezi Sang,Xiao Ze,Bi Li,Junju Su,Yuan Wang,Ning Guan,Xiaoyang Zhao,Suxin Gui,Liyuan Zhu,Zhe Cheng,Jie Cheng,Lei Sheng,Qingqing Sun,Ling Wang,Fashui Hong +17 more
TL;DR: TiO2 NPs could be translocated and accumulated in brain, led to oxidative stress, overproliferation of all glial cells, tissue necrosis as well as hippocampal cell apoptosis, and microarray data showed significant alterations in the expression of 249 known function genes, which may be potential biomarkers of brain toxicity caused by TiO1 NPs exposure.
Journal ArticleDOI
Nanosized TiO2-Induced Reproductive System Dysfunction and Its Mechanism in Female Mice
Xiaoyang Zhao,Yuguan Ze,Guodong Gao,Xuezi Sang,Bing Li,Suxin Gui,Lei Sheng,Qingqing Sun,Jie Cheng,Zhe Cheng,Renping Hu,Ling Wang,Fashui Hong +12 more
TL;DR: Fertility reduction and ovary injury of mice following exposure to nano-TiO2 may be associated with alteration of inflammation-related or follicular atresia-related cytokine expressions, and humans should take great caution when handling nano- TiO2.
