Project description:Cooccurrence of Familial Non Medullary Thyroid Cancer (FNMTC) and Hereditary Non Polyposis Colorectal Cancer (HNPCC) Associated Tumors A Cohort Study
Project description:To identify a microRNA profile of human medullary thyroid cancer (MTC), we performed a miRNA microarray analysis exploiting 8 primary tumours and 9 paired neck nodes metastases in comparison with 3 non-neoplastic thyroid tissues.

Project description:We report gene expression profiling in a series of 17 human medullary thyroid cancer (MTC) tissues, including 8 primary tumors and 9 patient paired neck nodes metastases, in comparison with 3 non-neoplastic thyroid tissues. For the same series we have previously reported miRNA expression profiles (GSE97070 series).
Project description:Familial nonmedullary thyroid cancer (FNMTC) is a disease with the inheritance pattern is autosomal dominant with incomplete penetrance, but the causative gene is not clear. To identify the disease related locus in the FNMTC family, whole-genome SNPs of nine family members (five affected and four unaffected) were genotyped. We analyzed the SNP data with a novel method and mapped the disease-causing gene to several regions on the whole genome.
Project description:Although many genetic studies on thyroid cancers using different approaches have been conducted, just a few loci have been systematically associated. Given the difficulties to obtain single-loci associations this work focuses on the study of epistatic interactions that could help to understand the genetic architecture of complex diseases and explain new heritable components of genetic risk. To our knowledge, this is the first genome-wide epistatic screening for epistasis ever performed in thyroid cancer. Here, we analyzed both sporadic medullary thyroid cancer (sMTC) and juvenile papillary thyroid cancer (PTC) patients. We have identified two significant epistatic gene interactions in sMTC (CHFR-AC016582.2 and C8orf37-RNU1-55P) and three in juvenile PTC (RP11-648k4.2-DIO1, RP11-648k4.2-DMGDH and RP11-648k4.2-LOXL1). Interestingly, each interacting gene pair included a non-coding RNA, providing thus support to the relevance that these elements are increasingly gaining to explain cancer development and progression. Overall, this study contributes to the understanding of the genetic basis of thyroid cancer susceptibility in two different case scenarios such as sMTC and juvenile PTC. It opens further ways of knowledge of new heritable components of genetic risk to disease through association and statistical viewpoints.

Project description:Medullary thyroid cancer (MTC) accounts for less than 5% of all thyroid cancers, and it is a rare neuroendocrine tumor which derives from calcitonin-secreting thyroid C cells.Given the underlying mechanism involved in MTC remain unclear, the development and the specific pathways of MTC require further investigation.here we employed the application of TMT6plex-based LC-MS/MS to identify and analyze the novel differentially-expressed proteins(DEPs) from MTC patients, To our best knowledge, it is the first study to comprehensively investigate the molecular mechanisms of MTC by proteomics technology from Chinese MTC patients’ tissues, and these DEPs identified in our study will provide a better understanding of the underlying pathophysiology of MTC, as well as may provide potential therapeutic targets for patients with MTC.
