Abstract
BACKGROUND/AIM Papillary Thyroid Cancer (PTC) is the most common type of endocrine malignancy. Although PTC has an excellent prognosis, the recurrent or metastatic disease could affect patients' survival. Recent studies show that Histone Deacetylase Inhibitors (HDACIs) might be promising anticancer agents against PTC. The aim of this review is to evaluate the role of HDACIs as an additional modality in PTC treatment and to depict the latest trends of current research on this field. MATERIALS AND METHODS This literature review was performed using the MEDLINE database. The search strategy included terms: "thyroid cancer", "papillary", "HDAC", "histone", and "deacetylase". RESULTS Agents, such as Suberoyl Anilide Hydroxamic Acid, Trichostatin A, Valproic Acid, Sodium butyrate, Panobinostat, Belinostat, Romidepsin, CUDC907 and N-Hydroxy-7-(2-naphthylthio)-Hepanomide have shown promising anti-cancer effects on PTC cell lines but fail to trigger a major response in clinical trials. CONCLUSION HDACIs have no significant effect as monotherapy against PTC, but further research needs to be conducted in order to investigate their potential effect when used as an additional modality.

The intratumor microbiome predicts prognosis across gender and subtypes in papillary thyroid carcinoma. Comput Struct Biotechnol J 2021; 19:1986-1997.

Abstract
While the intratumor microbiome has become increasingly implicated in cancer development, the microbial landscape of papillary thyroid carcinoma (PTC) is essentially uninvestigated. PTC is characterized by varied prognosis between gender and cancer subtype, but the cause for gender and subtype-based dissimilarities is unclear. Women are more frequently diagnosed with PTC, while men suffer more advanced-staged PTC. In addition, tall cell variants are more aggressive than classical and follicular variants of PTC. We hypothesized that intratumor microbiome composition distinctly alters the immune landscape and predicts clinical outcome between PTC subtypes and between patient genders. Raw whole-transcriptome RNA-sequencing, Level 3 normalized mRNA expression read counts, and DNA methylation 450 k sequencing data for untreated, nonirradiated tumor, and adjacent normal tissue were downloaded from the Genomic Data Commons (GDC) legacy archive for 563 thyroid carcinoma patients. Microbe counts were extracted using Pathoscope 2.0 software. We correlated microbe abundance to clinical variables and immune-associated gene expression. Gene-set enrichment, mutation, and methylation analyses were conducted to correlate microbe abundance to characterize microbes' roles. Overall, PTC tumor tissue significantly lacked microbes that are populated in adjacent normal tissue, which suggests presence of microbes may be critical in controlling immune cell expression and regulating immune and cancer pathways to mitigate cancer growth. In contrast, we also found that microbes distinctly abundant in tall cell and male patient cohorts were also correlated with higher mutation expression and methylation of tumor suppressors. Microbe dysbiosis in specific PTC types may explain observable differences in PTC progression and pathogenesis. These microbes provide a basis for developing specialized prebiotic and probiotic treatments for varied PTC tumors.

Resistance to Src inhibition alters the BRAF-mutant tumor secretome to promote an invasive phenotype and therapeutic escape through a FAK>p130Cas>c-Jun signaling axis. Oncogene 2019; 38:2565-2579.

Abstract
Few therapy options exist for patients with advanced papillary and anaplastic thyroid cancer. We and others have previously identified c-Src as a key mediator of thyroid cancer pro-tumorigenic processes and a promising therapeutic target for thyroid cancer. To increase the efficacy of targeting Src in the clinic, we sought to define mechanisms of resistance to the Src inhibitor, dasatinib, to identify key pathways to target in combination. Using a panel of thyroid cancer cell lines expressing clinically relevant mutations in BRAF or RAS, which were previously developed to be resistant to dasatinib, we identified a switch to a more invasive phenotype in the BRAF-mutant cells as a potential therapy escape mechanism. This phenotype switch is driven by FAK kinase activity, and signaling through the p130Cas>c-Jun signaling axis. We have further shown this more invasive phenotype is accompanied by alterations in the secretome through the increased expression of pro-inflammatory cytokines, including IL-1β, and the pro-invasive metalloprotease, MMP-9. Furthermore, IL-1β signals via a feedforward autocrine loop to promote invasion through a FAK>p130Cas>c-Jun>MMP-9 signaling axis. We further demonstrate that upfront combined inhibition of FAK and Src synergistically inhibits growth and invasion, and induces apoptosis in a panel of BRAF- and RAS-mutant thyroid cancer cell lines. Together our data demonstrate that acquired resistance to single-agent Src inhibition promotes a more invasive phenotype through an IL-1β>FAK>p130Cas>c-Jun >MMP signaling axis, and that combined inhibition of FAK and Src has the potential to block this inhibitor-induced phenotype switch.

Abstract
Anaplastic thyroid cancer (ATC) is an aggressive malignancy with poor prognosis. It was reported that Forkhead box D3 (FOXD3) transcription factor is associated with several cancers. We investigated its antitumorigenic role of ATC in this study. The ATC cell lines SW1736 and K18 exhibited lower FOXD3 expression than the Nthy-ori-3-1 normal thyroid cell line. FOXD3 downregulation in ATC cell lines promoted invasiveness and epithelial-to-mesenchymal transition (EMT) and decreased cellular apoptosis. FOXD3 silencing also enhanced p-ERK levels in the ATC cell lines, suggesting it negatively regulated MAPK/ERK signaling. Silencing FOXD3 in SW1736 cells also led to generation of larger xenograft tumors with high p-ERK and low E-cadherin levels. Moreover, human ATC samples showed lower FOXD3 and higher p-ERK levels than samples of normal thyroid tissue. These findings demonstrate that FOXD3 acts as a tumor suppressor during anaplastic thyroid carcinogenesis and highlight its potential for clinical application.

Abstract
Lenvatinib, a novel potent multikinase inhibitor, was approved for the treatment of radioiodine-refractory differentiated thyroid cancer based on results from phase III trial (SELECT study). Thyroid cancer is a diverse disease that includes anaplastic thyroid cancer (ATC), which the most aggressive form of the disease, although it accounts for <2% of all thyroid cancers. Current treatments for ATC have limited efficacy. We report the case of a woman with recurrent well-differentiated papillary carcinoma of the thyroid that had transformed into ATC who developed a perforation of the small intestine secondary to a marked effect of lenvatinib. She received lenvatinib (24 mg once a day) at only two doses during two weeks due to pleurodesis with talc for malignant pleural effusion. Eventually, she developed peritonitis due to the perforation and died of sepsis. However, an autopsy revealed marked efficacy of lenvatinib for ATC at a metastatic site in the small intestine despite limited exposure to the drug. Here, we report on our experience with lenvatinib treatment and gastrointestinal perforation concerning anti-angiogenic therapy.

Abstract
Thyroid carcinoma (TC) is the most common malignancy of the endocrine organs, and its incidence rate has steadily increased over the last decade. For medullary thyroid cancer (MTC), a type of TC, a high mortality rate has been reported. In previous studies, M-phase phosphoprotein 8 (MPHOSPH8) displayed an elevated expression in various human carcinoma cells. Thus, MPHOSPH8 may be a sensitive biomarker that could be used for the diagnosis and follow-up of MTC. In the present study, plasmids of RNA interference targeting the MPHOSPH8 gene were constructed. Once these lentiviruses targeting MPHOSPH8 were transfected into the MTC cell line TT, cell viability and proliferation were measured by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Flow cytometry was used to assess the cell cycle distribution and apoptosis. The expression levels of MPHOSPH8 were detected by reverse transcription quantitative-polymerase chain reaction and western blot analyses. Depletion of MPHOSPH8 significantly inhibited cell proliferation. Furthermore, knockdown of MPHOSPH8 in TT cells led to G0/G1 phase cell cycle arrest and apoptosis. The results of the present study suggest that MPHOSPH8 promotes cell proliferation and may be a potential target for anticancer therapy of MTC.

Abstract
The oncogenic activation of the rearranged during transfection (RET) proto-oncogene has a main role in the pathogenesis of medullary thyroid cancer (MTC). Several lines of evidence suggest that RET function could be influenced by cyclic AMP (cAMP)-dependent protein kinase A (PKA) activity. We evaluated the in vitro anti-tumor activity of 8-chloroadenosine-3',5'-cyclic monophosphate (8-Cl-cAMP) and PKA type I-selective cAMP analogs [equimolar combination of the 8-piperidinoadenosine-3',5'-cyclic monophosphate (8-PIP-cAMP) and 8-hexylaminoadenosine-3',5'-cyclic monophosphate (8-HA-cAMP) in MTC cell lines (TT and MZ-CRC-1)]. 8-Cl-cAMP and the PKA I-selective cAMP analogs showed a potent anti-proliferative effect in both cell lines. In detail, 8-Cl-cAMP blocked significantly the transition of TT cell population from G2/M to G0/G1 phase and from G0/G1 to S phase and of MZ-CRC-1 cells from G0/G1 to S phase. Moreover, 8-Cl-cAMP induced apoptosis in both cell lines, as demonstrated by FACS analysis for annexin V-FITC/propidium iodide, the activation of caspase-3 and PARP cleavage. On the other hand, the only effect induced by PKA I-selective cAMP analogs was a delay in G0/G1-S and S-G2/M progression in TT and MZ-CRC-1 cells, respectively. In conclusion, these data demonstrate that cAMP analogs, particularly 8-Cl-cAMP, significantly suppress in vitro MTC proliferation and provide rationale for a potential clinical use of cAMP analogs in the treatment of advanced MTC.

Abstract
The in vitro and in vivo uptake, toxicological analysis and anti-angiogenic theranostic prospect of FITC loaded (FITC-Si) and suramin loaded (Sur-Si) silica nanoparticles are presented. FITC/suramin encapsulated silica nanoparticles (NPs) with an average size of <30 nm were synthesized. The uptake of FITC-Si by human umbilical vein endothelial cells (HuVECs) (in vitro) and by early stage medaka embryos (in vivo) was monitored by fluorescence microscopy. The nanoformulation was found to be biocompatible with both cells and embryos. The cytotoxicity analysis, tubulogenesis and migration assay confirmed the anti-angiogenic potential of Sur-Si NPs in HuVECs. The imaging of medaka embryos exposed to FITC-Si, their survival and hatching rate and biocompatibility post FITC-Si exposure were documented. The in vivo drug delivery mediated anti-angiogenic potential of Sur-Si NPs was assessed by survival and hatching rate analysis along with morphological indicators. At higher concentrations, Sur-Si proved lethal to embryos, whereas at lower concentrations it was rather an efficient anti-angiogenic formulation leading to malformed vasculogenesis and inhibited intersegmental vessel formation in an efficient dose dependent mode. The results indicate the potential application of such nanoformulation in future anti-angiogenic theranostics.

Abstract
Anaplastic thyroid cancer (ATC) is a rare but aggressive malignancy of the thyroid. No effective treatment modalities are currently available. Targeted therapy against protein kinases showed promising results in preclinical studies. Our goal was to assess the mutational status of potential therapeutic targets, as well as the biomarker for immunotherapy in the clinical context. Using allele specific PCR, Sanger sequencing, fragment analysis and immunohistochemistry, we assessed BRAF, KRAS, EGFR mutations and protein overexpression of C-KIT and PDL1 in anaplastic thyroid cancer specimens. Results were compared to clinical information and patient outcome to assess the utility of these biomarkers. There were 13 patients in our study with a median overall survival of 19 weeks. Of the 13 ATC patients, 3 (23 %) had BRAF V600E mutation. C-KIT overexpression was found in 1 (8 %) patient who responded well to a tyrosine kinase inhibitor. PDL1 expression was seen in 3 (23 %) patients, none of them were surgical candidates due to unresectability and poor performance status. KRAS codon 12/13 and EGFR exon 18, 19, 20 and 21 were all wild type in our patients. Protein kinase inhibitors and immunotherapy may be useful adjuvant therapies for ATC.

Abstract
Background Thyroid cancer is the most common endocrine tumor with a steady increase in incidence. It is classified into multiple histopathological subtypes with potentially distinct molecular mechanisms. Identifying the most relevant genes and biological pathways reported in the thyroid cancer literature is vital for understanding of the disease and developing targeted therapeutics. Results We developed a large-scale text mining system to generate a molecular profiling of thyroid cancer subtypes. The system first uses a subtype classification method for the thyroid cancer literature, which employs a scoring scheme to assign different subtypes to articles. We evaluated the classification method on a gold standard derived from the PubMed Supplementary Concept annotations, achieving a micro-average F1-score of 85.9% for primary subtypes. We then used the subtype classification results to extract genes and pathways associated with different thyroid cancer subtypes and successfully unveiled important genes and pathways, including some instances that are missing from current manually annotated databases or most recent review articles. Conclusions Identification of key genes and pathways plays a central role in understanding the molecular biology of thyroid cancer. An integration of subtype context can allow prioritized screening for diagnostic biomarkers and novel molecular targeted therapeutics.

Abstract
Thyroid cancer (TC) is the most common type of endocrine malignancy and accounts for nearly 3 % of all malignancies. The incidence of TC in Spain was 5/100,000 in women and 1.9/100,000 in men in 2013. The diagnosis of TC usually follows the identification of a thyroid nodule on physical examination or as an incidental finding on diagnostic imaging performed for other reasons. In most of the cases, the prognosis is excellent but despite low mortality rates, local recurrence occurs in up to 20 %, and distant metastases can occur in approximately 10 % at 10 years. The better knowledge of molecular biology of TC has allowed to the development of new targeted agents directed to the main pathways involved in TC pathogenesis. Knowing all these new strategies will help us face the therapeutic management of TC more effectively.

Abstract
Despite that thyroid cancer accounts for over 90% of tumors that arise from the endocrine system, these tumors barely represent 2% of solid tumors in adults. Many entities are grouped under the general term of thyroid cancer, and they differ in histological features as well as molecular and clinical behavior. Thus, the prognosis for patients with thyroid cancer ranges from a survival rate of >97% at 5 years, in the case of differentiated thyroid tumors sensitive to radioactive iodine, to a 4-month median survival for anaplastic tumors. The high vascularity in these tumors and the important role that oncogenic mutations may have in the RAS/RAF/MEK pathway and oncogenicity (as suggested by activating mutations and rearrangements of the RET gene) have led to the development of multitarget inhibitors in different histological subgroups of patients. The correct molecular characterization of patients with thyroid cancer is thought to be a key aspect for the future clinical management of these patients.

Abstract
Cancer arises as the consequence of mutations and epigenetic alterations that activate oncogenes and inactivate tumor suppressor genes. Through a genome-wide screen for methylated genes in colon neoplasms, we identified aberrantly methylated RET in colorectal cancer. RET, a transmembrane receptor tyrosine kinase and a receptor for the glial cell-derived neurotrophic factor family ligands, was one of the first oncogenes to be identified, and has been shown to be an oncogene in thyroid cancer and pheochromocytoma. However, unexpectedly, we found RET is methylated in 27% of colon adenomas and in 63% of colorectal cancers, and now provide evidence that RET has tumor suppressor activity in colon cancer. The aberrant methylation of RET correlates with decreased RET expression, whereas the restoration of RET in colorectal cancer cell lines results in apoptosis. Furthermore, in support of a tumor suppressor function of RET, mutant RET has also been found in primary colorectal cancer. We now show that these mutations inactivate RET, which is consistent with RET being a tumor suppressor gene in the colon. These findings suggest that the aberrant methylation of RET and the mutational inactivation of RET promote colorectal cancer formation, and that RET can serve as a tumor suppressor gene in the colon. Moreover, the increased frequency of methylated RET in colon cancers compared with adenomas suggests RET inactivation is involved in the progression of colon adenomas to cancer.
