BACKGROUND: Both platelet-derived microRNAs and the genotype of CYP2C19*2 were implicated for the variability of clopidogrel antiplatelet responsiveness. However, their interaction on the antiplatelet responsiveness of clopidogrel in patients with acute coronary syndrome (ACS) remains unknown. METHODS: Consecutive clopidogrel-treated patients with ACS were recruited, with their antiplatelet responsiveness evaluated by the relative platelet inhibition (RI), as measured by light transmittance aggregometry (LTA) at baseline and 5days' after the maintenance treatment of clopidogrel...

Emerging reports suggest microRNAs (miRNAs) play a vital role in the progression of malignant tumors. MiR-30a is downregulated in a variety of cancers and acts as a tumor suppressing gene. However, the molecular mechanisms of miRNA-30a in hepatocellular carcinoma (HCC) are still unclear. Hereby, in this study, we detected that miR-30a expression was significantly down-regulated in both HCC tissues compared with adjacent non-cancerous liver tissues, and we also observed that miR-30a expression was lower in HCC cell lines than that of normal controls...

Triple-negative breast cancer (TNBC) has the worst prognosis of all subtypes of breast cancer (BC), with limited options for conventional therapy and no targeted therapies. MicroRNAs (miRNAs) are small noncoding RNAs that negatively regulate gene expression. In this study, we aimed to determine whether two members of the miR-200 family, miR-200b-3p and miR-429-5p, are involved in BC cell proliferation and motility and to elucidate their target genes and pathways. We performed a meta-analysis that reveals down-regulated expression of miR-200b-3p and miR-429-5p in BC tissues and cell lines, consistent with a lower expression of miR-200b-3p and miR-429-5p in MDA-MB-231 and HCC1937 cells than in MCF-7 and MCF-10 cells...

Gastric cancer is one of the most common cancers and has the highest mortality rate worldwide. It is worthwhile to explore the mechanism of gastric cancer progression. An increasing number of studies have found that non-coding RNAs including miRNA and lncRNA play important roles in gastric cancer progression. This review summarized the role of ectopic miRNA in gastric cancer proliferation, growth, migration, invasion and apoptosis. Meantime, aberrantly expressed miRNA also received a great deal of attention as potential biomarker for gastric cancer diagnosis and therapy...

miRNAs play a key role in the regulation of gene networks in mammalian cells. However, little is known about their roles and functions in the apoptosis pathway. Here, we conducted a whole-genome miRNA screening for apoptosis and identified more than 100 miRNAs as apoptosis inducers. To further explain the roles of these mRNAs in apoptosis, a second round of screening was conducted between p53 +/+ and -/- cells. Among the hits, miR-596 was identified as a regulator of p53. The overexpression of miR-596 significantly increased p53 at the protein level, thereby inducing apoptosis...

Adult rattlesnakes within genus Crotalus express one of two distinct venom phenotypes, type I (haemorrhagic) and type II (neurotoxic). In Costa Rican Central American rattlesnake, ontogenetic changes in the concentration of miRNAs modulate venom type II to type I transition. Venomics and venom gland transcriptome analyses showed that adult C. simus and C. tzabcan expressed intermediate patterns between type II and type I venoms, whereas C. culminatus had a canonical type I venom. Neonate/juvenile and adult Mexican rattlesnakes showed notable inter- and intraspecific variability in the number, type, abundance and ontogenetic shifts of the transcriptional and translational venom gland activities...

Due to global climate change, temperature stress has become one of the primary causes of crop losses worldwide. Much progress has been made in unraveling the complex stress response mechanisms in plants, particularly in the identification of temperature stress responsive protein-coding genes. Recently discovered microRNAs (miRNAs) and endogenous small-interfering RNAs (siRNAs) have also been demonstrated as important players in plant temperature stress response. Using high-throughput sequencing, many small RNAs, especially miRNAs, have been identified to be triggered by cold or heat...

Increasing evidence has demonstrated that miRNAs play a critical role in tumor development and progression. Previous studies have revealed that miR-106a is abnormally expressed in various cancers. However, its function and underlying mechanism in cervical cancer (CC) remains unknown. In this study, we confirmed that the expression of miR-106a was significantly upregulated in both CC cell lines and tissues by qRT-PCR. The increased expression of miR-106a was obviously associated with adverse prognostic features...

Atrial fibrillation (AF) is the most frequently occurring, persistent cardiac arrhythmia, and the hallmark of AF‑dependent structural remodeling is atrial fibrosis. Connective tissue growth factor (CTGF) is important in the process of fibrosis. The association between miRNA and CTGF in AF‑dependent fibrosis remains to be elucidated. The present study aimed to determine if microRNA (miR)‑132 was able to regulate CTGF with an anti‑fibrotic effect in AF. A total of ten dogs or patients were assigned to control (n=4) and AF groups (n=6)...

Head and neck squamous cell carcinoma is typically characterized by a high incidence of local recurrences. It has been extensively shown that mucosa from head and neck squamous cell carcinoma patients carries both genetic and gene expression alterations, which are mostly attributable to major etiologic agents of head and neck squamous cell carcinoma. We previously identified a signature of microRNAs (miRNAs) whose high expression in tumors is predictive of recurrence. Here, we investigated whether the deregulation of miRNA expression in the tumor-surrounding mucosa is correlated to disease recurrence...

OBJECTIVE: The discovery of specific microRNAs (miRNA) mediates a better understanding of molecular mechanisms, diagnosis and prognosis of complex phenotypes. Synthesis of the RhD blood group involves multiple factors causing variation in the expression of RHD antigens. The mechanism underlying the extremely weak expression of RHD antigen associated with the RHD variant called DEL (D-elute) is incompletely understood. Down-regulation of gene expression through miRNA is a guide to the potential involvement of miRNAs in the DEL blood group...

Cancer is one of the most difficult diseases to be treated. The particularities regarding the tumors' occurrence mechanism, their evolution under chemotherapy, disease-free interval, but also the increasing number of patients make cancer an intensively studied health domain. Although introduced in therapy since the early 80s, platinum derivatives play an essential role in anticancer therapy. Their use in therapy resulted in improving the patient quality of life and prolonging disease-free interval, which makes them still a benchmark for other anticancer compounds...
