Project description:3 papillary thyroid cancer cell lines were compared, treated with Y15 to untreated. 1 million cells of each papillary thyroid cell line (TPC1, K1, BCPAP) were plated, treated 24 hours later with 10uM Y15, and collected 24 hours later by trypsinization.
Project description:Tumor microenvironment heterogeneity sheltered our understanding of papillary thyroid cancer. However, molecular characteristics of papillary thyroid cancer has not been reported at single cell resolution. The immunological link between papillary thyroid cancer and Hashimoto's thyroiditis is also in doubt.We identified 24 cell clusters in human papillary thyroid cancer based on their heterogeneous gene expression pattern. Follicular epithelial cell subsets in papillary thyroid cancer with Hashimoto's thyroiditis and papillary thyroid cancer without Hashimoto's thyroiditis showed different malignant level. Machine learning model identified potential biomarker to evaluate tumor epithelial cell development. Together with immunostaining, lymphocytes heterogeneity indicated an obvious B cell infiltration pattern in papillary thyroid cancer with Hashimoto's thyroiditis. Additionally, trajectory analysis of B cell and plasma cell suggest the migration potential from normal adjacent tissue of Hashimoto's thyroiditis to papillary thyroid cancer tissue. Our results provide the first single cell landscape of Papillary thyroid cancer. Single cell data resource of Papillary thyroid cancer with Hashimoto's thyroiditis promote our understanding of molecular heterogeneity and immunological link between papillary thyroid cancer and Hashimoto's thyroiditis.
Project description:The gene expression profiles were identified in colon cancer cell lines treated either with Y15 or with 5-FU SW620 and Lovo-1 colon cancer cell lines were treated with 10 microM Y15 for 24 hours or with 5-FU 200 microM for 24 hours and compared treated to untreated
Project description:Anaplastic thyroid carcinoma (ATC) is a rare but deadly thyroid cancer. In contrast, papillary thyroid carcinoma (PTC) is common and highly curable. Minimally invasive biomarkers are needed to distinguish ATC and PTC. Here, by small RNA-seq we show the differential expression levels of several miRNAs, which include miR-34a and miR-210 in ATC compared to PTC cell lines.
