Abstract:
Human cervical cancer is the most common gynecological malignancy. The continuous development of nanotechnology has allowed the wide use of nanomaterials in cancer treatment. Nanoparticles can be used as gene carriers because of their surface effect and small-size effect. MicroRNA-let-7c-5p (miR-let-7c-5p) belongs to the let-7 family. Although it has been reported to exert a tumor suppressive effect in a variety of cancers, the exact role and mechanism of miR-let-7c-5p in the progression of cervical cancer are unclear. In this study, we synthesized flower-shaped SiO2 –PEI nanoparticles with hi

Abstract:
Osteoporosis is a progressive bone disease characterized by decreased bone mass and density, which usually parallels a reduced antioxidative capacity and increased reactive oxygen species formation. Adipose-derived mesenchymal stem cells (ADMSCs), a population of self-renewing multipotent cells, are a well-recognized source of potential bone precursors with significant clinical potential for tissue regeneration. We previously showed that overexpressing stearoyl-CoA desaturase 1 (SCD-1) promotes osteogenic differentiation of mesenchymal stem cells. Micro-RNAs (miRNAs) are noncoding RNAs recentl

Abstract:
The let-7c family of micro-RNAs (miRNAs) is expressed during embryonic development and plays an important role in cell differentiation. We have investigated the role of let-7c in heart regeneration after injury in adult zebrafish. let-7c antagomir or scramble injections were given at one day after cryoinjury (1 dpi). Tissue samples were collected at 7 dpi, 14 dpi and 28 dpi and cardiac function was assessed before cryoinjury, 1 dpi, 7 dpi, 14 dpi and 28 dpi. Inhibition of let-7c increased the rate of fibrinolysis, increased the number of proliferating cell nuclear antigen (PCNA) positive cardi

Background. Oxidative stress is an important factor during age-related cataract formation. Apoptosis and autophagy induced by oxidative stress have been reported as key factors in age-related cataract. In our research, we investigated the role of let-7c-3p in the regulation of autophagy and apoptosis during the formation of age-related cataract. Material and Methods. Real-time PCR and western blot were employed to detect the expression of let-7c-3p in the tissues of age-related cataract.

The purpose of the present study was to investigate the expressions of hsa-let-7c-5p and TGF-β signaling-related molecules and their correlations with clinical characteristics in chronic kidney disease (CKD). Twenty-three biopsy specimens of CKD patients and 20 negative control tissues were selected. Quantitative real-time PCR (qPCR) was used for the detection of hsa-let-7c-5p, transforming growth factor β (TGF-β) and TGF-β receptor type 1 (TGF-βR1) expression levels. Target gene of hsa-let-7c-5p was verified by dual-luciferase reporter assay. A significant decrease of hsa-let-7c-5p expression

Abstract:
ABSTRACT Activation of peroxisome proliferator-activated receptor α (PPARα) leads to hepatocellular proliferation and liver carcinomas. The early events mediating these effects are unknown. A novel mechanism by which PPARα regulates gene expression and hepatocellular proliferation was uncovered. MicroRNA (miRNA) expression profiling demonstrated that activated PPARα was a major regulator of hepatic miRNA expression. Of particular interest, let-7C, an miRNA important in cell growth, was inhibited following 4-h treatment and 2-week and 11-month sustained treatment with the potent PPARα agonist W

This study was focused on identifying the effects of single nucleotide polymorphisms (SNPs) located on an entire region of the let-7c miRNA gene with consideration of its ability to promote litter size in Markhoz goats. The Markhoz goat, the native breed in Iran, is important for its reproductive traits, such as litter size. DNA polymorphism of let-7c miRNA gene was revealed and considered for further studies for its effect on litter size in Markhoz goats. PCR-SSCP analysis investigated different band patterns for this miRNA; however, sequencing results have detected only an A to T substitutio

Introduction Tyrosyl-DNA phosphodiesterase 1 (TDP1) can repair oxidative damage-caused 3′-phosphoglycolates and promote cancer progression. However, the clinical significance of TDP1 and its correlation with microRNAs (miRNAs) in gastric cancer (GC) remains unknown. Methods The relationship of TDP1 or let-7c-5p with the clinical outcomes of GC was determined by a tissue microarray and TCGA dataset. Cell viability and invasion were assessed by MTT and Transwell assays. Pearson correlation analysis, luciferase gene report, qRT-PCR, and Western blot analyses were used to analyze the interaction b

Abstract:
Acute chest syndrome (ACS) is among the most serious complications of sickle cell disease (SCD). While the pathogenesis of ACS is incompletely understood, endothelial damage and microvascular occlusion are critical components. Our previous studies have implicated small extracellular vesicles in the plasma of subjects with SCD in causing endothelial dysfunction. This suggested that microRNAs within these small EVs might be responsible for endothelial damage. The sequencing of microRNAs in small EVs from the plasma of subjects with SCD revealed that several miRNAs were differentially expressed b
