Project description:Retrospective series of primary breast cancer patients who received surgery between 1989 and 1992. Patients received adjuvant chemotherapy and/or adjuvant hormone therapy, or no adjuvant treatment. Tamoxifen was used as endocrine therapy for 5 years in ER+ BC patients. Patients who were <50 years of age, with lymph node positive tumors, or ER– and/or >3 cm in diameter, received adjuvant cyclophosphamide, methotrexate, and 5-fluorouracil (CMF) for six cycles, in a thrice weekly intravenous regimen. Patients >50 years of age with ER–, lymph node–positive tumors also received CMF. Retrospective clinical study to identify breast cancer prognostic markers and associated pathways. 210 early primary breast cancers were considered who had complete 10-years follow-up, clinical and demographics information. miRNA profiling data.

Project description:MicroRNA (miRNA/miR) miR526b and miR655 overexpressed tumor cell-free secretions promote breast cancer phenotypes in the tumor microenvironment (TME). However, the mechanisms of miRNA regulating TME have never been investigated. With mass spectrometry analysis of MCF7-miRNA-overexpressed versus miRNA-low MCF7-Mock tumor cell secretomes, we identified 34 novel secretory proteins coded by eight genes YWHAB, TXNDC12, MYL6B, SFN, FN1, PSMB6, PRDX4, and PEA15 those are differentially regulated. We used bioinformatic tools and systems biology approaches to identify these markers’ role in breast cancer. Gene ontology analysis showed that the top functions are related to apoptosis, oxidative stress, membrane transport, and motility, supporting miRNA-induced phenotypes. These secretory markers expression is high in breast tumors, and a strong positive correlation exists between upregulated markers’ mRNA expressions with miRNA cluster expression in luminal A breast tumors. Gene expression of secretome markers is higher in tumor tissues compared to normal samples, and immunohistochemistry data supported gene expression data. Moreover, both up and downregulated marker expressions are associated with breast cancer patient survival. miRNA regulates these marker protein expressions by targeting transcription factors of these genes. Premature miRNA (pri-miR526b and pri-miR655) are established breast cancer blood biomarkers. Here we report novel secretory markers upregulated by miR526b and miR655 (YWHAB, MYL6B, PSMB6, and PEA15) are significantly upregulated in breast cancer patients’ plasma, and are potential breast cancer biomarkers.

Project description:The aim of our study is to develop a miRNA marker panel prognostic of 5-year survival in early-stage OSCC patients. We assessed differential expression of miRNAs genome-wide via deep sequencing in 100 tumor tissue samples. We also attempted to identify deregulated miRNA expression signatures that may serve as the prognostic markers.

Project description:There is a need for reliable prognostic markers that can guide therapeutic intervention in Crohn’s disease (CD). We examined whether different behavioral phenotypes in CD can be classified based on colonic miRNA or mRNA expression and if miRNAs have prognostic utility for CD. We perform high-throughput sequencing of small RNA and mRNA isolated from colon tissue from CD patients and non-IBD (NIBD) controls. To identify miRNA and genes associated with specific behavioral phenotypes of CD, patients were stratified according to disease behavior (non-stricturing, non-penetrating; stricturing; penetrating) and compared miRNA profiles in each class with those of the NIBD group. Using a novel statistical simulation approach applied to colonic RNA-seq data for CD patients and NIBD controls, we identify at drivers of gene expression profiles associated with CD.
