MicroRNAs (miRs) are expected to serve as prognostic tools for cancer. However, many miRs have been reported as prognostic markers of recurrence or metastasis in oral squamous cell carcinoma patients. We aimed to determine the prognostic markers in early-stage tongue squamous cell carcinoma (TSCC). Based on previous studies, we hypothesized that miR-10a, 10b, 196a-5p, 196a-3p, and 196b were prognostic markers and we retrospectively performed miR expression analyses using formalin-fixed paraffin-embedded sections of surgical specimens...

MicroRNA (miRNA), non-coding segments of RNA involved in post-transcriptional regulation of protein expression, are differentially expressed in eutopic endometrium of women with and without endometriosis compared to endometriotic lesions. However, endometriotic lesion types are known to be biochemically distinct and therefore hypothesized that miRNAs are differentially expressed in endometriomas compared to peritoneal and deep-infiltrating lesions. Therefore endometrial biopsies and ectopic implants from women (n = 38) undergoing laparoscopic surgery for chronic pelvic pain were collected...

Pediatric spinal ependymomas (SEPN) are important albeit uncommon malignant central nervous system tumors with limited treatment options. Our current knowledge about the underlying biology of these tumors is limited due to their rarity. To begin to elucidate molecular mechanisms that give rise to pediatric SEPN, we compared the transcriptomic landscape of SEPNs to that of intracranial ependymomas using genome-wide mRNA and microRNA (miRNA) expression profiling in primary tumour samples. We found that pediatric SEPNs are characterized by increased expression of genes involved in developmental processes, oxidative phosphorylation, cellular respiration, electron transport chain, and cofactor metabolic process...

BACKGROUND/AIM: KRAS and BRAF are two genes commonly mutated in colorectal cancer (CRC). Even though BRAF is a downstream target of KRAS in the MAPK signalling pathway, KRAS- and BRAF-mutated CRCs are found to display several different clinical and histopathological features. We investigated whether a differential expression of microRNAs (miRNAs) could explain the clinicopathological differences seen between KRAS- and BRAF-mutated CRCs. MATERIALS AND METHODS: Using a PCR array, we analyzed the expression of 84 different miRNAs in CRC cell lines wild-type in KRAS and BRAF, or mutated in KRAS or BRAF...

MicroRNAs (miRNAs/miRs) are small non-coding RNAs identified in plants, animals and certain viruses; they function in RNA silencing and post-transcriptional regulation of gene expression. miRNAs also serve an important role in the pathogenesis, diagnosis and treatment of tumors. However, few studies have investigated the role of miRNAs in thyroid tumors. In the present study, the expression of miRNA and mRNA was compared between follicular thyroid carcinoma (FTC) and follicular thyroid adenoma (FA) samples, and then miRNA-mRNA regulatory network analysis was performed...

Notch signaling as a conserved cell fate regulator is involved in the regulation of cell quiescence, proliferation, differentiation and postnatal tissue regeneration. However, how Notch signaling regulates porcine satellite cells (PSCs) has not been elucidated. We stably transfected Notch1 intracellular domain (N1ICD) into PSCs to analyze the gene expression profile and miRNA-seq. The analysis of the gene expression profile identified 295 differentially-expressed genes (DEGs) in proliferating-N1ICD PSCs (P-N1ICD) and nine DEGs on differentiating-N1ICD PSCs (D-N1ICD), compared with that in control groups (P-Control and D-Control, respectively)...

Binge drinking is commonly associated with high risk of cardiovascular diseases although the underlying mechanism remains elusive. Advances in genomics and genetics have indicated a number of alcohol-responsive genes in alcohol drinking behavior and alcoholic organ injury. Recent findings revealed a dramatic rise in mircoRNA-10a (miR-10a) and miR-21 levels with binge drinking (Beech et al., 2014). Given the increased knowledge in the past decade on the role of non-coding RNAs in the regulation of cardiovascular function, the identification of novel microRNA and underlying cellular mechanisms in alcoholism and alcoholic organ complication suggests therapeutic promises for the interventions against alcoholic complications...

Non-protein coding RNA, miRNAs (microRNAs), are a class of promising molecular biomarkers for forensic body fluid identification (BFI) as their small size and tissue-specific expression manners. A number of studies have shown that semen can be distinguished from forensic-related body fluids (such as menstrual blood, venous blood, vaginal fluid, saliva, etc.) using semen-specific miRNAs through microassay screening and RT-qRCR. Infertility is becoming a global health problem, affecting 10%-15% of couples worldwide, and half of the cases are the result of male factors (Lian et al...

BACKGROUND/AIMS: Hypoxic/ischemic injury to the liver is a frequently encountered clinical problem with limited therapeutic options. Since microRNAs (miRNAs) are involved in hypoxic/ ischemic events, and δ-opioid receptor (DOR) is protective against hypoxic/ischemic injury, we asked if pharmacological activation of DOR can alter hypoxic events by regulating miRNA expression in the liver. As the first step, the present work aimed at testing the effect of DOR activation on hepatic miRNA expression in hypoxia...

MicroRNAs (miRNAs) have important posttranscriptional regulatory abilities, and there is considerable interest in evaluating their expression patterns in different pathophysiological states. The most common method of quantifying miRNA expression is quantitative reverse transcription PCR; however, the identification of tissue-specific and species-specific reference miRNA is a prerequisite for miRNA expression analysis. Currently, no reference genes have been described for evaluating miRNA expression in equine serum and chorioallantoic membrane (CAM) during pregnancy...

Increasing studies showed that long non-coding RNAs (lncRNAs) played important roles in the development and progression of tumors. Previous evidences suggested that Tumor suppressor candidate 7 (TUSC7) was involved in several tumors initiation. However, the role of TUSC7 in colorectal cancer is still unknown. In this study, we indicated that the expression of TUSC7 was downregulated in colorectal cancer cell lines and tissues. Moreover, the expression of TUSC7 was lower in the high-grade (Dukes C and D) colorectal cancer patients compared to that in the low-grade colorectal cancer patients (Dukes A and B)...
