Project description:To investigate the pathogenesis of malignant phyllodes tumors of the breast, we used lncRNA+mRNA microarray expression profiling as a platform to investigate lncRNAs that play a key role in the malignant progression of phyllodes tumors of the breast.A total of 4 cases of breast fibroadenomas, 6 cases of benign phyllodes tumors and 6 cases of malignant phyllodes tumors were included. Fibroadenomas and benign phyllodes tumors were used as controls to screen out significantly differentially expressed lncrnas in malignant phyllodes tumors.
Project description:WG-DASL expression of breast fibroepithelial lesions Breast fibroepithelial lesions are biphasic tumors and include fibroadenomas and phyllodes tumors. Fibroadenomas are clinically benign while phyllodes tumors are more unpredictable in biological behavior, with potential for recurrence. Differentiating the tumors may be challeneging when they have overlapping clinical and histological features especially on the core biopsies
Project description:Genome wide DNA methylation profiling of phyllodes tumour, fibroadenoma and metaplastic breast cancer samples. The Illumina Infinium Methylation EPIC v1.0 BeadChip Array was used to obtain DNA methylation profiles across approximately 866,000 CpGs from primary tumours. Samples included a range of grades of phyllodes tumours (n=29), fibroadenoma (n=2), and metaplastic breast cancer (n=2).
