The murine Six gene family, homologous to Drosophila sine oculis (so) which encodes a homeodomain transcription factor, is composed of six members (Six1-6). Among the six members, only the Six2 gene has been previously shown to be expressed early in kidney development, but its function is unknown. We have recently found that the Six1 gene is also expressed(More)
The homeobox Six genes, homologues to Drosophila sine oculis (so) gene, are expressed in multiple organs during mammalian development. However, their roles during auditory system development have not been studied. We report that Six1 is required for mouse auditory system development. During inner ear development, Six1 expression was first detected in the(More)
Eyes absent (Eya) genes regulate organogenesis in both vertebrates and invertebrates. Mutations in human EYA1 cause congenital Branchio-Oto-Renal (BOR) syndrome, while targeted inactivation of murine Eya1 impairs early developmental processes in multiple organs, including ear, kidney and skeletal system. We have now examined the role of Eya1 during the(More)
While much work has been conducted regarding the neurogenesis response to traumatic brain injury (TBI) in rodents, it remains largely unknown whether neurogenesis in adult human brain also responds to TBI in a similar manner. Here, we performed immunocytochemistry on 11 brain specimens from patients with traumatic brain injury, who underwent surgical(More)
Little is known about the function of microRNAs in prolactinomas treated with bromocriptine. The aim of the study was to explore the microRNAs associated with bromocriptine-treated prolactinomas. Six prolactinoma samples were selected according to whether they received bromocriptine treatment or not before microsurgery,(More)
Mitochondrial mutational spectra in human cells, tissues and derived tumors for bp 10,030-10,130 are essentially identical, suggesting a predominant mutagenic role for endogenous processes. We hypothesized that errors mediated by mitochondrial DNA polymerase gamma were the primary sources of mutations. Point mutations created in this sequence by human DNA(More)
A role for the Notch signalling pathway in the formation of arteriovenous malformations during development has been suggested. However, whether Notch signalling is involved in brain arteriovenous malformations in humans remains unclear. Here, we performed immunohistochemistry on surgically resected brain arteriovenous malformations and found that, compared(More)
Up-regulation of Notch4 was observed in the endothelial cells in the arteriovenous malformations (AVMs) in mice. However, whether Notch4 is also involved in brain AVMs in humans remains unclear. Here, we performed immunohistochemistry on normal brain vascular tissue and surgically resected brain AVMs and found that Notch4 was up-regulated in the subset of(More)
The occurrence of an inherent or acquired resistance to temozolomide (TMZ) is a major burden for patients suffering from glioma. Recently, studies have demonstrated that microRNAs play an important role in the regulation of tumor properties in cancers. However, whether miR-497 contributes to glioma resistance to chemotherapy is not fully understood. In this(More)
A label-free, multiplexed DNA assay using fluorescent conjugated polymers as a detection probe to illustrate hybridization on metallic striped nanorods is demonstrated. Different DNA capture probes were encoded by the different reflectivities of Au and Ag stripe patterns. Successful DNA hybridization induced an optically detectable conformational change in(More)
