Sensory neurons adopt distinct morphologies and functional modalities to mediate responses to specific stimuli. Transcription factors and their downstream effectors orchestrate this outcome but are incompletely defined. Here, we show that different classes of mechanosensory neurons in C. elegans are distinguished by the combined action of the transcription factors MEC-3, AHR-1, and ZAG-1. Low l...

Estrogen has a cardiovascular protective role in women due in part to its effect on the vasculature. The roles of the two estrogen receptors (ERs), ER and ER , in the vascular actions of estrogen are unclear, as are effects of estrogen on microvascular endothelial cells (MEC) derived from sex steroid-responsive tissues. The present study demonstrates that 17 -estradiol, but not progesterone, in...

Inhibition of cyclooxygenase (COX) 2, which is associated with >40% of breast cancers, decreases the risk of tumorigenesis and breast cancer recurrence. To study the role of COX-2 in breast cancer, we engineered mice that lack selectively mammary epithelial cell (MEC) COX-2 (COX-2 KO(MEC)). Compared with wild type (WT), MEC from COX-2 KO(MEC) mice expressed >90% less COX-2 messenger RNA (mRNA) ...

The 2006 International Conference on Scientific Computing (CSC’06) Abstract Partitions of a plane, based on two or three of its points, are introduced. The study of these partitions is applied to finding the minimal enclosing circle (MEC) for a set S of n planar points. MEC(S), the MEC of n points of S, is defined by either a pair of S points with the largest distance (tight two-tuple) or by a ...

Although rare, mucoepidermoid carcinoma (MEC) is one of the most common malignant salivary gland tumors. The presence of the t(11;19)(q21;p13) translocation in a subset of MECs has raised interest in genomic aberrations in MEC. In the present study we conducted genome-wide copy-number-aberration analysis by micro-array comparative-genomic-hybridization on 27 MEC samples.Low/intermediate-grade M...

BACKGROUND Mucoepidermoid carcinoma (MEC) is an uncommon malignancy. To the best of our knowledge, this is the largest study investigating disease-specific survival (DSS) of parotid MEC and the first population-level study of the distribution of nodal metastases. METHODS Patients with MEC of the parotid gland were identified in the Surveillance, Epidemiology, and End Results (SEER) database (...

Fucoidan is a sulfated polysaccharide present in brown algae that has been identified to exhibit multiple biological effects. In this study, the apoptotic effects of fucoidan in MC3 human mucoepidermoid carcinoma (MEC) cells were investigated. The apoptotic effects of fucoidan on MC3 MEC cells were evaluated by cell proliferation assay, 4',6-diamidino-2-phenylindole staining and western blot an...

BACKGROUND Mucoepidermoid carcinoma (MEC) is the most common malignant salivary gland tumor. The majority of MECs occur in major or intraoral minor salivary glands. Herein, we present a case of MEC metastatic to cervical lymph nodes with an unknown primary site and discuss diagnostic and treatment options. METHODS AND RESULTS The patient was a 43-year-old man who presented with a large right-...

Primary pulmonary neoplasms rarely occur in children, but the majority of those that do are malignant. Mucoepidermoid carcinoma (MEC) represents ~10% of all primary pulmonary malignant tumors. However, MEC is not usually considered in the clinical differential diagnosis in pediatric practice. The present study presents the case of a seven-year-old female with a one-year history of recurrent hem...
