Predicting the metabolomic impact of deregulated microRNAs in lung squamous cell carcinoma

Project description:We have previously defined key metabolomic changes in Lung Squamous Cell Carcinoma (LSCC) compared to histologically normal tissues (Paes de Araújo et al., 2019). Here our goals were to define microRNA changes in the same tissues, in addition to verifying the detection of deregulated microRNAs in plasma from the same patients.

TAp63-regulated microRNAs suppress cutaneous squamous cell carcinoma

Project description:TAp63-regulated microRNAs suppress cutaneous squamous cell carcinoma

| PRJNA609900 | ENA

Project description:MicroRNAs play a crucial role in tumorigenesis. However, the value of microRNAs in the diagnosis and treatment of tongue squamous cell carcinoma (TSCC) still await investigations. To identify the microRNAs associated with the metastasis of TSCC, we analyzed the transcriptomic difference between metastatic and the non-metastatic TSCC tissue. We identified a set of metastasis-related microRNAs with potential prognostic value.

Differential Expression of microRNAs in Oral Squamous cell carcinoma (OSCC) [Frozen tissue samples]

Project description:Our objective was to analyze with microarray the differential expression of microRNAs in oral squamous cell carcinoma compared with healthy control tissue. We have obtained a total of 97 genes desregulated, 36 overexpressed and 61 under expressed, where 81 were microRNAs.

The microRNAs with potential in predicting lung metastasis of triple negative breast cancer

Project description:To identify lung metastasis associated microRNAs in triple negative breast cancer (TNBC), we have employed the commercially available Agilent Human miRNA V19.0 Microarray (Platform GPL19730) as a discovery platform. In comparison with LM-Normal, 11 microRNAs significantly altered in both LM-Met and LM-Tumor, and then three of them (hsa-miR-21-3p, hsa-miR-21-5p and hsa-miR-211-3p) were excluded, which were also up-regulated in RF-Tumor. Consequently, eight deregulated microRNAs were identified to be putatively involved in process of lung metastasis, especially miR-629-3p, which was most up-regulated in both LM-Met and LM-Tumor. To validate the microarray data, we utilized qRT-PCR to assess expression levels of the eight miRNAs in the same samples.

A five-microRNA-signature predicting recurrence in HNSCC

Project description:The risk of locoregional or distant failure in advanced HPV-negative head and neck squamous cell carcinoma (HNSCC) patients is high. However, no suitable markers for stratification are clinically available. Thus, we aimed to identify a microRNA(miRNA)-signature predicting disease recurrence. For this purpose the miRNA profiles from 162 HNSCC samples were analysed with regard to identification of a low-complex porgnostic signature. The data set consists of a discovery dataset (n=85) and a validation dataset (n=77). The study resulted in a prognostic 5-miRNA signature significantly predicting the relevant clinical endpoint freedom from recurrence.

Differential expression of microRNAs between oral squamous cell carcinoma and healthy control tongues

Project description:In order to identify aberrantly expressed microRNAs in oral squamous cell carcinomas (OSCCs), we have employed microRNA microarray profile using healthy tongue samples as control. All seventeen human OSCCs and three normal tongue tissues were collected from the Tissue Bank at the Moffitt Cancer Center and approved by the University of Florida institutional review board. Majority (15 out of 17) of the OSCCs were derived from tongue cancers. The tumor samples contained greater than 80% of cancerous cells, confirmed by microscopic examination by a head and neck pathologist. The normal tongues were taken from a non-cancerous region. Tissues were snap-frozen and stored at -80M-BM-0C until further use. Total RNAs were isolated from human tissues using mirVana miRNA Isolation kit (Ambion/Applied Biosystems, Austin, TX) according to the manufacturerM-bM-^@M-^Ys instruction. NanoDropM-BM-. ND-100 spectrophotometer (Thermo Scientific, Wilmington, DE) was used to quantify the isolated RNA. The Agilent 2100 Bioanalyzer from the Interdisciplinary Center for Biotechnology Research at the University of Florida was used to detect the size distribution of total RNA and to determine the quality as well. Expression of microRNAs from this signature was quantified in the same RNA samples by real-time PCR, confirming the expression pattern. Human tissues of oral squamous cell carcinoma and healthy normal tongues were used for microRNA microarray profile to identify aberrantly expressed microRNAs in oral squamous cell carcinomas.
