چکیده

Thyroidtumors (TC) are the most common endocrine cancer, accounting for ۹۰% of allendocrine neoplasms (۱).Thyroid cancer will be the fourth most common cancer in the United States by۲۰۳۰, after lung, liver, and pancreatic cancers (۲).Histological classification indicates that papillary thyroid carcinoma (PTC) isa differentiated thyroid cancer that originates from the thyroid's follicularcell epithelium (۳).It accounts for ۸۰–۸۵% of all instances, making it the most common category ofTC (۴).This study uses a dual method, single-cell analysis, and system biologyanalysis in response to the growing need for efficient treatments for papillarythyroid cancer. Through investigating the complexities of tumor heterogeneityand investigating possible targets for immunotherapy, the study seeks to openup new options for more accurate and focused treatments in the context ofpapillary thyroid cancer. This bioinformatics study aims to investigate thedifference in cell population in papillary thyroid cancer and normal thyroidcells, and their gene markers.Material and Methods:R language was used for analyzing the scRNA-seq data (GSE۱۹۳۵۸۱, GSE۱۵۸۲۹۱ and GSE۲۳۲۲۳۷) using the Seurat (۵), Celldex and SingleCellExperiment packages (۶, ۷). ۷۱۸۲۳ cells from ۱۶ samples including:۱۰ papillary thyroid cancer and ۶ normal. To evaluate dimensionality reductionand cell clustering, PCA and t-SNE were performed. To identify different celltypes and automated cluster annotation singleR package was used. Next analysespertaining to the biological system were conductedResults:Compared to normal tissue, DLGAP۵ was highly expressed in papillarythyroid cancer compared with normal thyroid cancer. Systems biology studies have alsodemonstrated that this gene exhibits elevated expression in papillary thyroidcancer, indicating its potential as both a diagnostic and therapeuticbiomarker.Conclusion:Possible immune-related biomarkershave been found through an analysis of the connection between the papillarythyroid and the immune system. These results can be used to establish clinically usefuldiagnostic and treatment strategies for papillary thyroid carcinoma.References: ۱. Crnčić TB, Tomaš MI, Girotto N, Ivanković SG.

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
