MicroRNAs are a class of small noncoding RNAs that have been implicated in regulation of a broad range of cellular and physiologic processes, including apoptosis. The objective of this study is to elucidate the roles of miR-125b in modulating ethanol-induced apoptosis in neural crest cells (NCCs) and mouse embryos. We found that treatment with ethanol(More)
Nuclear factor erythroid 2-related factor (Nrf2) is a key transcription factor that regulates antioxidant defense in cells. In this study, we investigated whether over-expression of Nrf2 can prevent ethanol-induced oxidative stress and apoptosis in neural crest cells (NCCs). We found that transfection of NCCs with pcDNA3.1-Nrf2 resulted in statistically(More)
Ethanol-induced apoptosis in selected cell populations is a major component of pathogenesis underlying ethanol-induced teratogenesis. However, there is a fundamental gap in understanding how ethanol leads to apoptosis in embryos. In this study, we investigate the role of seven in absentia homolog-1 (Siah1) protein, an E3 ubiquitin ligase, in ethanol-induced(More)
Neuroblastoma is the most common extra-cranial solid tumor in children. Despite advances in the treatment of childhood cancer, outcomes for children with advanced-stage neuroblastoma remain poor. Here we reported that 2-methoxyestradiol (2-ME) inhibited the proliferation and induced apoptosis in human neuroblastoma SK-N-SH and SH-SY5Y cells. 2-ME treatment(More)
Nrf2 is a transcription factor that regulates the induction of an expansive set of antioxidant proteins that act in synergy to remove reactive oxygen species (ROS). We have recently discovered that Nrf2 signaling is involved in the induction of antioxidant response in ethanol-exposed embryos. We have also demonstrated that chemically induced transcriptional(More)
PURPOSE A clinicopathologic study of all cases accessioned as calcifying odontogenic cyst (COC) from 1971 to 1996 from the files of the Oral Pathology Laboratory at Temple University School of Medicine was undertaken. MATERIALS AND METHODS Microscopic slides and clinical histories of cases diagnosed as calcifying odontogenic cyst were reviewed and(More)
We synthesized distorted octahedral (T') molybdenum ditelluride (MoTe2) and investigated its vibrational properties with Raman spectroscopy, density functional theory, and symmetry analysis. Compared to results from the high-temperature centrosymmetric monoclinic (T'mo) phase, four new Raman bands emerge in the low-temperature orthorhombic (T'or) phase,(More)
Turnover of focal adhesions allows cell retraction, which is essential for cell migration. The mammalian spectraplakin protein, ACF7 (Actin-Crosslinking Factor 7), promotes focal adhesion dynamics by targeting of microtubule plus ends towards focal adhesions. However, it remains unclear how the activity of ACF7 is regulated spatiotemporally to achieve focal(More)
In this article, we present the transport and magnetotransport of high-quality graphene transistors on conventional SiO(2)/Si substrates by modification with organic molecule octadecyltrichlorosilane (OTS) self-assembled monolayers (SAMs). Graphene devices on OTS SAM-functionalized substrates with high carrier mobility, low intrinsic doping, suppressed(More)
The two-fold valley degeneracy in two-dimensional (2D) semiconducting transition metal dichalcogenides (TMDCs) (Mo,W)(S,Se)2 is suitable for "valleytronics", the storage and manipulation of information utilizing the valley degree of freedom. The conservation of luminescent photon helicity in these 2D crystal monolayers has been widely regarded as a(More)
