Circulating miRNome of Trachemys scripta after elective gonadectomy

ABSTRACT: Pain management is an important issue in veterinary medicine, requiring biomarkers with high sensitivity and specificity for the timely and effective treatment. Emerging evidence suggests that miRNAs are promising pain-related markers. The aims were to profile the circulating miRNA signature in plasma of turtles (Trachemys scripta) and point out potential candidate biomarkers of pain. Plasma of female turtles underwent surgical gonadectomy were collected 24h pre-surgery, and 2.5h and 36 h post-surgery. The expression of miRNAs was profiled by Next Generation Sequencing and the dysregulated miRNAs were validated using RT-qPCR. The diagnostic value of miRNAs was calculated by ROC curves.

Gonadectomy-induced transcriptome changes in the ventral cervical spinal cord of male and female rats

Project description:Circulating sex steroids are critical for the development of neuroplasticity in the respiratory motor system. A primary locus of inducible respiratory neuroplasticity is the phrenic motor nucleus, a column of motor neurons in the ventral cervical spinal cord (C3-C5). In specific, exposure to acute intermittent hypoxia (AIH) induces strengthened synaptic connections to phrenic motor neurons and increased motor output; a form of neuroplasticity called phrenic long-term facilitation (pLTF). Gonadectomy (surgical removal of the testes in males and ovaries in females) reduces circulating sex steroids and eliminates AIH-induced phrenic pLTF in both females and males, implicating sex steroids as critical mediators for the development of neuroplasticity. To begin interrogating mechanisms of sex steroid influence on phrenic motor neurons and to determine the effect of gonadectomy on local gene expression, we performed RNA sequencing on ventral cervical spinal cord samples containing the phrenic motor nucleus. Our findings identified sex-specific gene expression in gonadally-intact rats and suggested that gonadectomy caused greater changes to the transcriptomes of male rats compared to females.

Comprehensive analysis of circulating microRNAs in plasma of patients with pituitary adenomas

Project description:Background: Circulating miRNAs in pituitary adenoma would help patient care especially in non-functioning adenoma cases as minimally invasive biomarkers of tumor recurrence and progression. Aim: Our aim was to investigate plasma miRNA profile in patients with pituitary adenoma. Materials and Methods: 149 plasma and extracellular vesicle (preoperative, early- and late postoperative) samples were collected from 45 pituitary adenoma patients. Adenomas were characterized based on anterior pituitary hormones and transcription factors by immunostaining. MiRNA next generation sequencing was performed on 36 samples (discovery set). Individual TaqMan assay was used for validation on extended sample set. PA tissue miRNAs were evaluated by TaqMan array and literature data. Results: Global downregulation of miRNA expression was observed in plasma samples of pituitary adenoma patients compared to normal samples. Expression of 29 miRNAs and isomiR variants were able to distinguish preoperative plasma samples and normal controls. MiRNAs with altered expression in both plasma and different adenoma tissues were identified. 3, 7 and 66 miRNAs expressed differentially between preoperative and postoperative plasma samples in growth hormone secreting, FSH/LH+ and hormone-immunonegative groups, respectively. MiR-143-3p was downregulated in late- but not in early postoperative plasma samples compared to preoperative ones exclusively in FSH/LH+ adenomas. Plasma level of miR-143-3p discriminated these samples with 81.8% sensitivity and 72.3% specificity (AUC=0.79; p=0.02). Conclusions: Differentially expressed miRNAs in pituitary adenoma tissues have low abundance in plasma minimizing their role as biomarkers. Plasma miR-143-3p decreases in patients with FSH/LH+ adenoma indicated successful surgery, but its application for evaluating tumor recurrence needs further investigation.

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.

Plasma miRNome analysis from retinoblastoma patients reveals the size of the circulating miRNome, a tumor signature and new normalizers candidates.

Project description:In This work we analyzed the mirnome in plasma and corresponding extracellular vesicles (EVs) from 12 patients affected by retinoblastoma (Rb) a childhood intraocular malignant tumor, as well as from 12 healthy aged matched controls. Using hierarchical clustering with the detection score microarrays provide for each miRNA and we identified a plasma signature of 19 miRNAs in all Rb cases that were able to discriminate both cases from controls.

Whole blood derived cadmium responsive miRNome

Project description:Purpose: Cadmium is a nonessential heavy metal and a well known toxic agent. Cadmium is known to alter the gene expression and signaling but the role of miRNAs during Cadmium exposure is not understood. Methods: Mice were treated with 100 mg/ ml cadmium chloride for 120 days and accumulation of cadmium in blood and organs are confirmed by GFAAS. Subsequently, the total RNA was isolated from the whole blood and small RNA sequencing was executed in Illumina HiSeq 1000. Results: The reads were annotated to the mice genome and miRNAs in miRbase using miRDeep* and novel miRNAs were also predicted. The differential expression was studied by DeSeq Conclusions: This is the first report to reveal the cadmium responsive miRNome. These candidate miRNAs can serve as biomarkers for cadmium Whole blood small RNA profiles of control and cadmium exposed mice generated by deep sequencing using Illumina HiSeq 1000
