Plasma circulating MiRNAs: a new potential biomarker for prostate cancer diagnosis.

Project description:Purpose: PCa is the second most commonly diagnosed malignancy in men. PCa Diagnosis are based on biopsy sampling that is an invasive, expensive procedure and does not accurately represent multifocal disease. It is desirable to have an easily accessible, minimally invasive way to accurately determine the molecular signature of patient’s tumor that can aid in diagnosis and risk stratification. Methods:we enrolled a total of 70 patients underwent 12-core transrectal ultrasound (TRUS) biopsy of which 48% had cancer in the diagnosis. The mean age at diagnosis was 67.15 (IR 55/75), the mean PSA (ng/ml) at diagnosis was 7.8 (IR 4.1/13.4) and the mean TRUS Volume (ml) was 53.5 (IR 29/86). The cancer biopsy presented 73.1% of positive core. Among all cancer patients, 57% showed a High grade of cancer status (Grade 3). Controls are patients with Benign Prostate Hyperplasia (BPH). MicroRNA-expression profiling (NGS analysis) was performed to identify tumor-related microRNAs (miRs) and determine their association with clinicopathological characteristics. Results: The expression of miRs -4732-3p, let7a, 26b-5p, 98-5p, 30c-5p and 21-5p may identified Prostate Cancer in plasma samples. Higher expression of mir-4732-3p is associated with a high grade tumor Conclusions: miRs signature discriminate Prostate cancer in plasma better to PSA values and is associated with high grade tumor status

A plasma miRNA-based classifier for small cell lung cancer diagnosis [NanoString]

Project description:Objectives: Small cell lung cancer (SCLC) is characterized by poor prognosis and challenging diagnosis. Screening in high-risk smokers results in a reduction in lung cancer mortality, however, screening efforts are primarily focused on non-small cell lung cancer (NSCLC). SCLC diagnosis and surveillance remain significant challenges. The aberrant expression of circulating microRNAs (miRNAs/miRs) is reported in many tumors and can provide insights into the pathogenesis of tumor development and progression. Here, we conducted a comprehensive assessment of circulating miRNAs in SCLC with a goal of developing a miRNA-based biomarker classifier to assist in SCLC diagnoses. Materials and Methods: We profiled deregulated circulating cell-free miRNA in the plasma of SCLC patients. We tested selected miRs on a training cohort and created a classifier by integrating miRNA expression and patient clinical data. Finally, we applied the classifier on a validation dataset. Results: We determined that miR-375-3p can discriminate between SCLC and NSCLC patients, and between SCLC and Squamous Cell Carcinoma patients. Moreover, we found that a model comprising miR-375-3p, miR-320b, and miR-144-3p can be integrated with race and age to distinguish metastatic SCLC from a control group. Conclusion: This study proposes a miRNA-based biomarker classifier for SCLC that considers clinical demographics with specific cut offs to inform SCLC diagnosis.

Analysis of circulating microRNAs in adrenocortical tumours

Project description:Differential diagnosis of adrenocortical adenoma and carcinoma is of pivotal clinical relevance, as the prognosis and clinical management of benign and malignant adrenocortical tumours is entirely different. Circulating microRNAs are promising biomarker candidates of malignancy in several tumours. In the present study we investigate circulating microRNAs in adrenocortical tumours and to evaluate their potential applicability as biomarkers of malignancy. For the miRNA profiling, 8 preoperative plasma samples obtained from patients with adrenocortical adenomas and carcinomas and were studied by microarray.

Effect of milk intake on circulating plasma miRNAs of adult humans

Project description:This study examines circulating plasma miRNAs of adult human subjects before and after bovine milk intake. We sought to confirm and expand findings previously reported by Baier, et al., J Nutr, 2014, PMID 25122645, using the same samples. Plasma samples were provided by the Zempleni lab (see Baier, et al., J Nutr, 2014, PMID 25122645) and had been taken from five healthy donors prior to milk intake (T0) and at three hours post-intake (T3). miRNA profiles were generated for each sample by OpenArray (Thermo Fisher).

Circulating miRNAs spectra in plasma of multiple myeloma patients compared with healthy individuals

Project description:MicroRNAs (miRNAs) are a class of small non-coding single-stranded RNAs whose dysregulation of expression plays an important role in cancer development. Circulating miRNAs are novel biomarkers in several cancers. Thus, we explored whether the miRNAs in plasma could be useful clinical biomarkers for multiple myeloma (MM) patients. The expression levels of four miRNAs in plasma were upregulated while eight miRNAs were downregulated in MM patients compared with healthy controls according to microarray. MiRNA microarray was conducted to determine deregulated miRNAs in plasma of 9 MM patients and 7 healthy controls.

Circulating miRNAs in maternal plasma as a potential biomarker of early pregnancy in sheep

Project description:We investigated the circulating microRNA expression profile of serum from sheep using microarray. In our study, we have six groups annotated as cyclic and pregnant, each group was divided into three subgroups including four animals in each group. We finally validated the microRNA of interest using qPCR.
