TLDR
Observations show the feasibility of developing plasma miRNA profiling as a sensitive and specific blood-based biomarker assay for pancreatic cancer that has the potential of translation to the clinic with additional improvements in the future.Abstract:
Development of minimally invasive biomarker assays for early detection and effective clinical management of pancreatic cancer is urgently needed to reduce high morbidity and mortality associated with this malignancy We hypothesized that if aberrantly expressing microRNAs (miRNA) in pancreatic adenocarcinoma tissues are detected in blood plasma, then plasma profiling of these miRNAs might serve as a minimally invasive early detection biomarker assay for this malignancy By using a modified protocol to isolate and quantify plasma miRNAs from heparin-treated blood, we show that miRNA profiling in plasma can differentiate pancreatic adenocarcinoma patients from healthy controls We have profiled four miRNAs, miR-21, miR-210, miR-155, and miR-196a, all implicated in the development of pancreatic cancer with either proven or predicted target genes involved in critical cancer-associated cellular pathways Of these, miR-155 has recently been identified as a candidate biomarker of early pancreatic neoplasia, whereas elevated expression of miR196a has been shown to parallel progression of disease The results revealed a sensitivity of 64% and a specificity of 89% with the analyses of plasma levels for this panel of four miRNAs The area under the receiver operating characteristic curve were estimated at 082 and 078 without and with leave-one-out cross-validation scheme, respectively These observations, although a "proof of principle" finding at this time, show the feasibility of developing plasma miRNA profiling as a sensitive and specific blood-based biomarker assay for pancreatic cancer that has the potential of translation to the clinic with additional improvements in the futureread more

Evaluation of dynamic change of serum miR-21 and miR-24 in pre- and post-operative lung carcinoma patients
TL;DR: Qualitative reverse transcription-polymerase chain reaction (qRT-PCR) is conducted to examine the expression of four miRNAs in the sera of a set of 82 pre-operative lung carcinoma patients and paired 10 days post-operative patients to suggest they may serve as potential novel non-invasive biomarkers for diagnosis of lung cancer.

TL;DR: It is shown here that miRNAs are present in human plasma in a remarkably stable form that is protected from endogenous RNase activity and established the measurement of tumor-derived mi RNAs in serum or plasma as an important approach for the blood-based detection of human cancer.

MicroRNA-21 is an antiapoptotic factor in human glioblastoma cells.
TL;DR: It is shown that the highly malignant human brain tumor, glioblastoma, strongly over-expresses a specific miRNA, miR-21, which may contribute to the malignant phenotype by blocking expression of critical apoptosis-related genes.
