Mechanistic Study of Fragile Site Breakage by Investigating RET/PTC Rearrangements, a Common Cause of Papillary Thyroid Carcinoma
Chromosomal fragile sites are non-random regions of the genome with a predisposition to the formation of DNA breaks. Common fragile sites, which are found in all individuals, often coincide with regions mutated in cancer, and therefore are believed to play a role in carcinogenesis. However, there …

Expression of X-linked Inhibitor of Apoptosis Protein in Neoplastic Thyroid Disorder
… and tumor recurrence in BRAFV600E prevalent PTC population. Expression of XIAP was evaluated with immunohistochemical staining using monoclonal anti-XIAP in 164 specimens of conventional papillary thyroid carcinoma (PTC) and 53 specimens of other malignant or benign thyroid tumors. The …

The U.S. wind production tax credit - evaluating its impact on wind deployment and assessing the cost of its renewal
… extension of the wind production tax credit (PTC) is routinely contested whenever a scheduled expiration approaches. While proponents of the policy argue that the policy is necessary for the wind energy industry to continue to expand, opponents contend that the wind energy industry no longer …

Leveraging copper chelators as targeted therapy for BRAFV600E mutant thyroid cancer
… and in particular papillary thyroid cancer (PTC), is rising faster than that of any other malignancy in the United States. Thyroid cancer is now the most common endocrine cancer and the fifth most common cancer in women. While most thyroid cancers are treated effectively with surgical …

Profilo Molecolare in una Coorte di Neoplasie Tiroidee Insorte nell'Area Vulcanica della Sicilia
… aumentata di tumori papillari della tiroide (PTC) è stata osservata nelle aree vulcaniche, a causa di una cronica esposizione a bassi livelli di inquinamento da metalli pesanti. Inoltre, individui con una storia di neoplasia pediatrica, sottoposti a chemioterapia e/o radioterapia, presentano …

Relation between F-18 FDG Uptake of PET/CT and BRAFV600E Mutation in Papillary Thyroid Cancer
… prognostic factors of papillary thyroid cancer (PTC). This study was performed to investigate the relationship between the BRAFV600E mutation and F-18 FDG uptake in PTC. MATERIALS AND METHODS: We retrospectively included 169 PTC patients who underwent F-18 FDG positron emission …

Genomic Characterization of Adolescent and Young Adult Cancers: Investigation of Ewing Sarcoma Susceptibility and Chornobyl Thyroid Tumors
… Sarcoma (EwS) and papillary thyroid carcinoma (PTC). In the EwS study, we describe the interplay between a somatic driver, EWSR1- FLI1, and a highly polymorphic GGAA microsatellite in the 6p25.1 EwS GWAS susceptibility locus, employing third generation long-read sequencing to explore the …

Phase transfer catalysis: catalyst screening, reaction development, and mechanism analysis
… rearrangement under phase transfer catalysis (PTC) reaction conditions was investigated. Supplementing these studies, a deeper understanding of the PTC mechanism was sought for the alkylation of phenol. In regards to the asymmetric PTC (APTC) alkylation, a small library of catalysts derived …

RET receptor activation targets expression of the pleiotropic cytokine interleukin-11
… are associated with papillary thyroid carcinoma (PTC). In gene expression screens, interleukin-11 was identified as a RET-responsive gene. We sought to characterize the expression of IL-11 in response to activation of the RET receptor, and determine how IL-11 might contribute to RET-mediated cell …

Investigation of microRNA expression in thyroid carcinoma among South Africa patients
… carcinoma (FTC) and papillary thyroid carcinoma (PTC). Real time PCR was employed to confirm the expression levels of miRNA- 21 and miRNA-122. Results: 17 miRNAs were upregulated in PTC and 14 in FTC. There were significant differences in the miRNA expression between FTC and PTC. For example, …

DNA FRAGILE SITE BREAKAGE AS A MEASURE OF CHEMICAL EXPOSURE AND PREDICTOR OF THE SUSCEPTIBILITY TO FORM CHROMOSOMAL REARRANGEMENTS
… of chromosomal rearrangements, we focused on RET/PTC rearrangements in papillary thyroid carcinoma. All genes participating in the two most common types of RET/PTC rearrangements, RET/PTC1 and RET/PTC3, are located within common fragile sites. Fragile sites are sensitive to a variety of …

Dysregulation of of phospholipid-specific phagocytosis by B1 B cells in diet-induced obese mice
… we investigate the unique phosphotidylcholine (PtC)-specific B1 B cell phagocytosis. PtC is a major phospholipid in the biological membrane and a classical antigen recognized by B1 B cell-derived natural antibodies. These antibodies play important roles in immune defense as well as tissue …
