Decamethylcyclopentasiloxane(D5) is one of the most common chemical ingredient for cosmetic products, cleansing agents, hairdye, dry cleaning solvent and personal hygiene supplies. D5 is also known as estrogenic chemical. It can be absorbed through skin, airosol, and even oraly. People are exposed to D5 in daily environment. However, the risk of prenatal exposure to D5 has not yet been fully understood. Recent research shows that imbalance of dam’s estrogen induces brain ...

Developmental toxicity tests have been made by embryonic stem cell tests at the European Centre for the Validation of Alternative Methods or by embryonic body test in our laboratory. However, no neuronal-specific developmental toxicity test has been made yet. Therefore, this study was carried out using a 46C cell line, mouse embryonic stem cells with an endogenous Sox1-GFP reporter, to exploit the developmental neurotoxicity test. The expression of Sox1, a marker for neural pr...

Mitochondria, which are essential organelles for endocrine health, plays an important role in various physiological functions including hormonal biosynthesis, cell metabolism, proliferation and differentiation. Thus, mitochondrial toxicity can affect a variety of organs, such as liver, heart, muscle, kidney, and central nervous system. Mitochondrial toxicity is recognized as a contributor to drug-induced toxicity of various drugs such as hydroxytamoxifen, valproic acid, acetam...

Mitochondria play a key role in hormone biosynthesis and involve in renal cell proliferation by producing about 90% of cellular energy and controlling cell apoptosis. Doxorubicin is commonly used for many tumor treatments. However, its clinical utility is limited by the adverse reactions, which are known to be nephrotoxic. The mechanism by which doxorubicin induced kidney damage is still not completely understood, however nephrotoxicity by doxorubicin might be related to mitoc...

Calcium signaling plays a regulatory role in the events of cellular proliferation. In immunocytes such as T cells, B cells, mast cells and many other cell types, Ca2+ signals show to control the proliferation, differentiation, and function. Furthermore, Ca2+ has been shown to act as a second messenger to regulate innate immune cell function and activation. Here, we found that loss of Nckx3, a potassium-dependent Na+ /Ca2+</...
