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...

S Padma, P Shanmuga Sundaram
Papillary and follicular cancers of thyroid are the most common varieties of differentiated thyroid cancers exhibiting excellent long-term prognosis when carefully managed. Being a slow-growing malignancy, guidelines exist on the staging, preoperative risk stratification, and management of these cancers to increase the overall survival of these patients. Radioactive iodine has a central role in differentiated thyroid malignancies. It has the same physical properties as stable iodine, thus both normal and malignant thyrocytes cannot differentiate radioactive from stable iodine...

BACKGROUND: The last few years have witnessed an increasing number of clinical research networks (CRNs) focused on building large collections of data from electronic health records (EHRs), claims, and patient-reported outcomes (PROs). Many of these CRNs provide a service for the discovery of research cohorts with various health conditions, which is especially useful for rare diseases. Supporting patient privacy can enhance the scalability and efficiency of such processes; however, current practice mainly relies on policy, such as guidelines defined in the Health Insurance Portability and Accountability Act (HIPAA), which are insufficient for CRNs (e...

INTRODUCTION: Immune cells utilize acetylcholine as a paracrine-signaling molecule. Many white blood cells express components of the cholinergic signaling pathway, and these are up-regulated when immune cells are activated. However, in vivo molecular imaging of cholinergic signaling in the context of inflammation has not previously been investigated. METHODS: We performed positron emission tomography (PET) using the glucose analogue 18F-FDG, and 11C-donepezil and 18F-FEOBV, markers of acetylcholinesterase and the vesicular acetylcholine transporter, respectively...

REVIEW
Sarah Aref, Katharine Bailey, Adele Fielding
Oncolytic virotherapeutic agents are likely to become serious contenders in cancer treatment. The vaccine strain of measles virus is an agent with an impressive range of oncolytic activity in pre-clinical trials with increasing evidence of safety and efficacy in early clinical trials. This paramyxovirus vaccine has a proven safety record and is amenable to careful genetic modification in the laboratory. Overexpression of the measles virus (MV) receptor CD46 in many tumour cells may direct the virus to preferentially enter transformed cells and there is increasing awareness of the importance of nectin-4 and signaling lymphocytic activation molecule (SLAM) in oncolysis...

BACKGROUND: Major regulation of thyroid gland function is mediated by thyrotropin (TSH) activating the TSH receptor (TSHR) and inducing upregulation of genes involved in thyroid hormone synthesis. Evidence suggests that the insulin-like growth factor 1 (IGF-1) receptor (IGF-1R) may play a role in regulating TSHR functional effects. This study examined the potential role of TSHR/IGF-1R crosstalk in primary cultures of human thyrocytes. RESULTS: TSH/IGF-1 co-treatment elicited additive effects on thyroglobulin (TG), thyroperoxidase (TPO), and deiodinase type 2 (DIO2) mRNA levels but synergistic effects on sodium-iodide symporter (NIS) mRNA...

Nanoclay can be incorporated into emerging dual functional drug delivery systems (DDSs) to promote efficiency in drug delivery and reduce the toxicity of doxorubicin (DOX) used for thyroid cancer treatment. This paper reports the expansion of the basal spacing of kaolinite nanoclay was expanded from 0.72 nm to 0.85 nm, which could provide sufficiently spacious site for hosting doxorubicin molecules and controlling the diffusion rate. A targeted design for papillary thyroid cancer cells was achieved by introducing KI, which is consumed by the sodium-iodide symporter (NIS)...

Hepatocellular carcinoma (HCC) is one of the most common malignant tumors worldwide. Currently, the clinical strategies available for the treatment of HCC remain insufficient for the poor prognosis. Sodium/iodide symporter (NIS)-based radioiodine therapy is proposed as a promising therapeutic strategy for the treatment of HCC. However, it is difficult for HCC cells to trap iodine for the lower expression of NIS. Small activating RNA (saRNA) is a newly identified small double-stranded RNA (dsRNA) that can induce endogenous gene expression by targeting promoter sequences...
