PURPOSE: Aberrant expression of human sodium iodide symporter (NIS) in breast cancer (BC) is well documented but the transcription factors (TF) regulating its aberrant expression is poorly known. We identify the presence of three p53 binding sites on the human NIS promoter sequence by conducting genome-wide TF analysis, and further investigate their regulatory role. METHODS: The differences in transcription and translation were measured by real-time PCR, luciferase reporter assay, site-directed mutagenesis, in vivo optical imaging, and chromatin immunoprecipitation...

Radioiodine uptake in the thyroid tissue, metastasis of differentiated thyroid cancer (DTC), and in other tissues, depends on the expression of sodium-iodide symporter (NIS). Vascular permeability, effusions, inflammation, and other mechanisms may also play a role in the accumulation of radioactive iodine. A 63-year-old woman underwent radioiodine therapy, as well as a post-therapy whole-body scan,as she was suspected of having lung metastasis from thyroid carcinoma. The scan not only showed uptake at the lung metastasis but also a faint diffuse bilateral uptake in the posterior thorax...

Vesicular stomatitis virus (VSV) is a negative-stranded RNA virus that naturally causes disease in livestock including horses, cattle and pigs. The two main identified VSV strains are the New Jersey (VSNJV) and Indiana (VSIV) strains. VSV is a rapidly replicating, potently immunogenic virus that has been engineered to develop novel oncolytic therapies for cancer treatment. Swine are a natural host for VSV and provide a relevant and well-established model, amenable to biological sampling to monitor virus shedding and neutralizing antibodies...

BACKGROUND: A diagnosis of breast cancer disrupts the life of the patient, but also the partner may experience adverse psychological effects. We examined partners' risk for first use of antidepressant medication, as a proxy for pharmacologically treated depression. METHODS: By linkage of national registers, we identified 1,420,592 depression-free men living with a cancer-free female partner in 1998-2011. During follow-up, breast cancer was diagnosed in female partners of 26,256 men...

AIMS: Metabolic Syndrome (MetS) is an important etiologic and prognostic factor for pancreatic cancer, but few studies have assessed health outcomes among hospitalized pancreatic cancer patients. We examined the associations between MetS and in-hospital outcomes, i.e. pancreatic resection, post-surgery complications, in-hospital mortality and discharge disposition among hospitalized patients with pancreatic cancer. METHODS: Using the Healthcare Cost and Utilization Project (HCUP) Nationwide Inpatient Sample (NIS) dataset from 2007 to 2011, we obtained data on 47,386 patients hospitalized with a primary diagnosis of pancreatic cancer...

Cancer cell metastasis is responsible for most cancer deaths. Non-invasive in vivo cancer cell tracking in spontaneously metastasizing tumor models still poses a challenge requiring highest sensitivity and excellent contrast. The goal of this study was to evaluate if the recently introduced PET radiotracer [(18)F]tetrafluoroborate ([(18)F]BF4(-)) is useful for sensitive and specific metastasis detection in an orthotopic xenograft breast cancer model expressing the human sodium iodide symporter (NIS) as a reporter...

Radioiodine whole body scan (WBS), related to sodium iodide symporter (NIS) function, is widely used to detect recurrence/metastasis in postoperative patients with thyroid cancer. However, the normal thymic uptake of radioiodine has occasionally been observed in young patients. We evaluated the expression of thyroid-related genes and proteins in the human thymus. Thymic tissues were obtained from 22 patients with thyroid cancer patients of all ages. The expression of NIS, thyroid-stimulating hormone receptor (TSHR), thyroperoxidase (TPO), and thyroglobulin (Tg) was investigated using immunohistochemistry and quantitative RT-PCR...

PURPOSE: Thyroid concentrates radioactive iodine by sodium-iodide symporter; this is used for treating hyperthyroidism and thyroid cancer. Pancreas expresses NIS and radioactive iodine uptake may damage pancreatic beta-cells and predispose patients to type 2 diabetes. The aim of this study was to determine whether radioactive iodine is associated with glucose metabolism in thyroidectomized rats. METHODS: Forty male Wistar rats were divided into four groups (n = 10/each); control, thyroidectomized, thyroidectomized-treated with 131-I (TX+I), and thyroidectomized-treated with 131-I and L-thyroxine (TX+I+T4)...

PURPOSE: The therapy of unresectable advanced thyroid carcinomas shows unfavorable outcome. Constitutive nuclear factor-κB (NF-κB) activation in thyroid carcinomas frequently contributes to therapeutic resistance; the radioiodine therapy often fails due to the loss of differentiated functions in advanced thyroid carcinomas. Curcumin is known for its anticancer properties in a series of cancers, but only few studies have focused on thyroid cancer. Our aim was to evaluate curcumin's molecular mechanisms and to estimate if curcumin could be a new therapeutic option in advanced thyroid cancer...

Active iodide (I(-)) transport in both the thyroid and some extrathyroidal tissues is mediated by the Na(+)/I(-) symporter (NIS). In the thyroid, NIS-mediated I(-) uptake plays a pivotal role in thyroid hormone (TH) biosynthesis. THs are key during embryonic and postembryonic development and critical for cell metabolism at all stages of life. The molecular characterization of NIS in 1996 and the use of radioactive I(-) isotopes have led to significant advances in the diagnosis and treatment of thyroid cancer and provide the molecular basis for studies aimed at extending the use of radioiodide treatment in extrathyroidal malignancies...

BACKGROUND: Breast cancer has emerged as a leading site of cancer among women in India. Fine needle aspiration cytology (FNAC) has been routinely applied in assessment of breast lesions. Cytological evaluation in breast lesions is subjective with a "gray zone" of 6.9-20%. Quantitative evaluation of nuclear size, shape, texture, and density parameters by morphometry can be of diagnostic help in breast tumor. AIMS: To apply nuclear morphometry on cytological breast aspirates and assess its role in differentiating between benign and malignant breast lesions with derivation of suitable cut-off values between the two groups...

Metastatic spinal cord compression (MSCC) is one of the most dreaded complications of cancer. A Nationwide Inpatient Sample (NIS) from 2000 to 2011 was used to extract data for all in-hospital stays of patients with MSCC using the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes. The usage and timing of radiation therapy and surgical interventions were identified using ICD-9-M codes. These interventions were defined as 'early intervention' if they were provided within the first 48 hours of hospitalization...
