Pancreatic Neuroendocrine Tumor Secreting Vasoactive Intestinal Peptide and Dopamine With Pulmonary Emboli: A Case Report

The vasoactive intestinal peptide-secreting neuroendocrine tumor (VIPoma) is a very rare pancreatic tumor. We report the first case of a patient with VIPoma that co-secreted dopamine and had pulmonary emboli.

Pheochromocytoma Screening Initiation and Frequency in von Hippel-Lindau Syndrome

Patients with von Hippel-Lindau (VHL) syndrome have a 25–30% chance of developing pheochromocytoma. Although practice guidelines recommend biochemical and radiological screening every 1–2 years for pheochromocytoma in patients with VHL, there are limited data on the optimal age and frequency for screening.

Epigenetic Regulation of the lncRNA MEG3 and Its Target c-MET in Pancreatic Neuroendocrine Tumors

Biallelic inactivation of MEN1 encoding menin in pancreatic neuroendocrine tumors (PNETs) associated with the multiple endocrine neoplasia type 1 (MEN1) syndrome is well established, but how menin loss/inactivation initiates tumorigenesis is not well understood. We show that menin activates the long noncoding RNA maternally expressed gene 3 (Meg3) by histone-H3 lysine-4...

Performance comparison of SNP detection tools with illumina exome sequencing data—an assessment using both family pedigree information and sample-matched SNP array data

To apply exome-seq-derived variants in the clinical setting, there is an urgent need to identify the best variant caller(s) from a large collection of available options. We have used an Illumina exome-seq dataset as a benchmark, with two validation scenarios—family pedigree information and SNP array data for the same samples, permitting global high-throughput cross-validation, to...

Testosterone regulates thyroid cancer progression by modifying tumor suppressor genes and tumor immunity

Cancer gender disparity has been observed for a variety of human malignancies. Thyroid cancer is one such cancer with a higher incidence in women, but more aggressive disease in men. There is scant evidence on the role of sex hormones on cancer initiation/progression. Using a transgenic mouse model of follicular thyroid cancer (FTC), we found castration led to lower rates of...

Molecular Classification of Thyroid Nodules Using High-Dimensionality Genomic Data

Objective: We set out to develop a molecular test that distinguishes benign and malignant thyroid nodules using fine-needle aspirates (FNA).

Expression of Vascular Endothelial Growth Factor-C in Benign and Malignant Thyroid Tumors

In contrast to vascular endothelial growth factor (VEGF), which stimulates angiogenesis, VEGF-C is thought to stimulate lymphangiogenesis. The role of VEGF-C in thyroid cancer pathogenesis has not been clarified. One might expect a different pattern of VEGF-C expression in the various types of thyroid cancer because of their different means of metastases. In this investigation...
