The fluorescence amplification strategy based on 3D DNA walker and CRISPR/Cas12a for the rapid detection of BRAF V600E.

Anal Sci 2022 Jun 3. Epub 2022 Jun 3.

Key Laboratory of Medical Diagnostics, Ministry of Education, College of Laboratory Medicine, Chongqing Medical University, Chongqing, 400016, People's Republic of China.

Circulating tumor DNA (ctDNA) is a fragment of single- or double-stranded DNA originating from tumor or circulating tumor cells and provides accurate information regarding the molecular characteristics of tumors. Therefore, sensitive detection of ctDNA is of great significance to mutation analysis and clinical diagnosis.

Radioactive iodine therapy: multiple faces of the same polyhedron.

Arch Endocrinol Metab 2022 May 12. Epub 2022 May 12.

Memorial Sloan Kettering Cancer Center, New York, NY, United States.

The incidence of differentiated thyroid carcinoma (DTC) has increased in recent decades with early stage, low risk papillary thyroid cancer (PTC) being detected and diagnosed. As a result, the psychological, financial, and clinical ramifications of overdiagnosis and excessively aggressive therapy are being increasingly recognized with many authorities calling for a re-evaluation of the traditional "one size fits all" management approaches. To address these critical issues, most thyroid cancer guidelines endorse a more risk adapted management strategy where the intensity of therapy and follow up is matched to the anticipated risk of recurrence and death from DTC for each patient.

Indian J Surg Oncol 2022 Mar 15;13(1):169-177. Epub 2022 Feb 15.

Department of General Surgery, Faculty of Medicine, Zagazig University, Zagazig, Egypt.

It is important to detect novel predictive biomarkers of cervical lymph node metastasis (CLNM) in papillary thyroid carcinoma (PTC) to help the surgeons in making early decision of performing central lymph node dissection and aggressive management strategies in selected high-risk patients, thus improving their prognosis. Zinc finger protein 703 (ZNF703) is a member of the neutrophil extracellular trap (NET) transcription factors family which has roles in proliferation and invasion of cancer cells. SMAD4 is a protein that has a role in cellular processes including cell proliferation, invasion, and metastasis through many genes' transcription. Read More

Prognostic significance of patient age in papillary thyroid carcinoma with no high-risk features.

Endocr J 2022 Apr 15. Epub 2022 Apr 15.

Department of Surgery, Kuma Hospital, Kobe 650-0011, Japan.

Older age is recognized as a predictor of poor prognosis in papillary thyroid carcinoma (PTC) patients. However, young age is associated with disease progression of PTC measuring 1 cm or smaller in patients on active surveillance. In this study, we investigated the relationship between patient age and prognosis of PTC belonging to very low-, low-, and intermediate-risk groups based on the guidelines published by the Japan Association of Endocrine Surgery in 2018.

Stress, Thyroid Dysregulation and Thyroid Cancer in Children and Adolescents. Proposed Impending Mechanisms.

Horm Res Paediatr 2022 Apr 6. Epub 2022 Apr 6.

Stress is a potential catalyst for thyroid dysregulation through cross-communication of the hypothalamic-pituitary-adrenal and hypothalamic-pituitary-thyroid (HPT) axes. Stress and stressors exposure motivates molecular mechanisms affecting compound feedback loops of the HPT axis. Whilst, there is evidence of connection between stress and thyroid dysregulation, the question whether this connection is implicated in the development of thyroid cancer (TC) remains unanswered.

The Subcellular Localization of IncRNA FAM230B in Osteosarcoma and Its Interaction with Early miR-203.

Crit Rev Eukaryot Gene Expr 2022 ;32(1):59-65

Department of Orthopaedic, The First Affiliated Clinical Hospital of Harbin Medical University, Nangang District, Harbin City, Heilongjiang Province, P.R. China.

Previous studies have revealed the role of lncRNA FAM230B in promoting papillary thyroid cancer and gastric cancer. We predicted that FAM230B may interact with miR-203 and studied the crosstalk between FAM230B and miR-203 in osteosarcoma (OS). Paired OS and nontumor tissues donated by 60 patients with OS were subjected to RNA isolations and quantitative real-time PCR (RT-qPCR) to analyze the expression of both FAM230B and miR-203 (mature and premature levels).

Proceedings of the North American Society of Head and Neck Pathology, Los Angeles, CA, March 20, 2022: DICER1-Related Thyroid Tumors.

Head Neck Pathol 2022 Mar 21;16(1):190-199. Epub 2022 Mar 21.

Department of Pathology, Brigham and Women's Hospital, Harvard Medical School, 75 Francis Street, Boston, MA, 02115, USA.

DICER1 syndrome is an autosomal dominant tumor predisposition syndrome caused by germline DICER1 mutations. In the thyroid, DICER1 syndrome is associated with early-onset multinodular goiter and thyroid carcinomas. Subsequent studies have shown that somatic DICER1 mutations, though rare, can occur in follicular-patterned thyroid tumors, such as follicular adenomas and follicular thyroid carcinomas, with a higher rate seen in pediatric follicular thyroid carcinomas and in follicular thyroid carcinomas with a macrofollicular architecture.

Division of General Surgery, Department of Surgery, Medical University of Vienna, Waehringer Guertel 18-20, 1090, Vienna, Austria.

Purpose: Papillary thyroid carcinoma (PTC) spreads early to lymph nodes (LN). However, prophylactic central (CND) and lateral neck dissection (LND) is controversially discussed in patients with clinically negative nodes (cN0). The preoperative prediction of LN metastasis is desirable as re-operation is associated with higher morbidity and poor prognosis. Read More

Emerging Role of Oxidative Stress on EGFR and OGG1-BER Cross-Regulation: Implications in Thyroid Physiopathology.

Cells 2022 02 26;11(5). Epub 2022 Feb 26.

Department of Medical, Oral and Biotechnological Sciences, University "G. d'Annunzio" Chieti-Pescara, Via dei Vestini 31, 66100 Chieti, Italy.

Thyroid diseases have a complex and multifactorial aetiology. Despite the numerous studies on the signals referable to the malignant transition, the molecular mechanisms concerning the role of oxidative stress remain elusive. Based on its strong oxidative power, HO could be responsible for the high level of oxidative DNA damage observed in cancerous thyroid tissue and hyperactivation of mitogen-activated protein kinase (MAPK) and PI3K/Akt, which mediate ErbB signaling.
