CircRNA sequencing analysis of PTMC with lateral lymph node metastases and related clinical value studies of circRNA.

Project description:High-throughput sequencing was used to detect the expression profile of circRNA in PTMC of lymph node metastasis in lateral cervical region, and RT-qPCR was used to detect the expression of circRNA in cancer tissues and normal tissues adjacent to cancer. The receiver operating characteristic (ROC) curve and the area under ROC curve (AUC) were used to evaluate whether CircRNAs could be used as a biomarker for the diagnosis of thyroid cancer. Bioinformatics was used to predict the PTMC-related ceRNA mechanism of lateral cervical lymph node metastasis.

Genetic expressions alteration affect on lateral neck node metastasis of thyroid papillary microcarcinoma

Project description:We performed oligonucleotide microarray analysis to assess the genetic expression alteration wich affected on lateral neck node metastasis of thyroid papillary microcarcinoma(PTMC). We performed microarray analysis in three PTMCs without cervical lymph-node metastases (N0), and five PTMCs with lateral neck-node metastasis (N1b) at initial diagnosis, using an Illumina HumanHT-12 v4.0 Expression BeadChip.

SDR9C7 Promotes Lymph Node Metastases in Patients with Esophageal Squamous Cell Carcinoma

Project description:To identify the lymph node (LN) metastasis-associated genes in primary ESCC tumors, gene expression proﬁling assay (GEP) was performed to identify the differences in gene expression profiles between primary ESCC tumors that were with LN metastases (N+) and those without LN metastases (N-).

Prognostic value of molecular intratumor heterogeneity in primary oral cancer and its lymph node metastases assessed by mass spectrometry imaging

Project description:Different aspects of intra-tumor heterogeneity (ITH), which are associated with development of cancer and its response to treatment, have postulated prognostic value. Here we searched for the potential association between phenotypic ITH analyzed by mass spectrometry imaging (MSI) and the prognosis of head and neck cancer. The study involved tissue specimens resected from 77 patients with locally advanced oral squamous cell carcinoma, including 37 patients where matched samples of primary tumor and synchronous lymph node metastases were analyzed. A 3-year follow-up was available for all patients that enabled their separation into two groups: with no evidence of disease (NED, n=41) and with progressive disease (PD, n=36). After the on-tissue trypsin digestion, peptide maps of all cancer regions were segmented using an unsupervised approach to reveal their intrinsic heterogeneity. We found that intra-tumor similarity of spectra was higher in the PD group and diversity of clusters identified during image segmentation was higher in the NED group, which indicated a higher level of ITH in patients with more favorable outcomes. Furthermore, signature of molecular components that correlated with long-term outcomes could be associated with proteins involved in the immune functions. Hence, we proposed that a higher level of ITH revealed by MSI in cancers with a better prognosis could reflect the presence of heterotypic components of tumor microenvironment such as infiltrating immune cells enhancing the response to the treatment. LC-MALDI-MS/MS data deposited in this repository originate from protein lysates obtained from FFPE sections consecutive to sections dedicated to MSI measurements. The hypothetical identity of the MSI components was established by assignment of a component location on the m/z scale for the measured masses of tryptic peptides identified by LC-MALDI-MS/MS allowing ±0.05% mass tolerance.

The Proteomic Fingerprint of Prostate Cancer in Primary Tumors and Recurrent Lymph Node Metastases

Project description:We performed a quantitative proteome comparison on formalin-fixed paraffin embedded (FFPE) tissue of metastasized and non-metastasized primary prostate cancer (PCa) and on recurrent lymph node metastases. Comparing these three sample groups, we aimed to identify proteins, that might potentially promote/supress tumor progression or metastasis formation. Proteins were quantified label-free. Proteins with interesting biological functions were followed-up by immunohistochemistry.

Expression data from 4T1 subclones derived from mammary fat pad tumors (MFP), axillary lymph node tumors (AxLN), and axillary lymph node-derived lung metastases (AxLN-LuM)

Project description:Expression data from 4T1 subclones derived from mammary fat pad tumors (MFP), axillary lymph node tumors (AxLN), and axillary lymph node-derived lung metastases (AxLN-LuM). In parallel, expression data, in the same subclones, of tail vein-derived (TV) lung metastases. The mechanism of how lymph node metastases seed distant metastases is unknown. We used the 4T1 breast cancer cell line, which is an immune competent model of triple negative breast cancer and spontaneously metastasizes in balb/c mice. 4T1-GFP/fLuc cells were injected into MFP to form tumors and 4T1-mCherry/rLuc cells were injected into axillary lymph nodes to form tumors and then allowed to metastasize to lung. TV cells were allowed to metastasize in the lung. Cells were harvested at different time intervals after the injection. Tumors were extracted, dissociated, and then expanded in vitro to obtain MFP, AxLN, AxLN-LuM and TV-LuM subclones isolated after different time lags with respect to the injection.

Gene expression profiling of primary tumors, lymph node and liver metastases in midgut carcinoid tumors.

Project description:In order to clarify the gene expression and identify genes involved in tumor progression, gene expression profiling was performed on tumor specimens. Samples comprised 18 primary tumors, 17 lymph node (LN) metastases and 7 liver metastases. Patients were grouped according to clinical data and histopathology into indolent or progressive course. RNA was subjected to a spotted oligo microarray and B-statistics were performed. Differentially expressed genes were verified using quantitative RT-PCR. Self-organising maps demonstrated three clusters. Eleven primary tumors separated in one cluster, 5 LN metastases in another whereas all liver metastases, 7 primary and 12 LN metastases, formed a third cluster. There was no correlation between indolent and progressive behaviour. The primary tumors with Ki67 > 5%, with low frequency of the carcinoid syndrome and a tendency towards shorter survival grouped together. Primary tumors differed in expression profile from their associated LN metastases. ACTG2, GREM2, REG3A, TUSC2, RUNX1, TPH1, TGFBR2 and CDH6 were differentially expressed between clusters and subgroups of tumors. The expression profile that assembles tumors as being genetically similar on the RNA expression level may not be concordant with the clinical disease course. This study reveals different gene expression profiles and novel genes not previously known to be involved in neuroendocrine tumorigenesis, and which may be of importance for tumor progression. Gene expression comparisons between 18 primary tumors, 17 lymph node metastases and 7 liver metastases.
