MicroRNA (miRNA) is a class of non‑coding RNA, which targets mRNAs of interest and suppresses its expression by degradation or translational inhibition. miRNA (miR)‑125a and miR‑125b were previously demonstrated to translationally and transcriptionally inhibit the expression of p53. The observed downregulation of the protein level of p53 in cisplatin‑treated patients with nasopharyngeal carcino...
Tumor suppressor protein p53 plays a crucial role in maintaining genomic integrity in response to DNA damage. Regulation of translation of p53 mRNA is a major mode of regulation of p53 expression under genotoxic stress. The AU/U-rich element-binding protein HuR has been shown to bind to p53 mRNA 3'UTR and enhance translation in response to DNA-damaging UVC radiation. On the other hand, the micr...
BACKGROUND Solitary fibrous tumors of the pleura (SFTP) are rare neoplasia of the chest. A subset of SFTP follows a malignant course, sometimes several years after complete resection. Traditional scoring systems based on clinical and histological features are poor predictors of biological behavior. This study aimed to investigate tumor-associated miRNAs expression as novel biomarkers to predict...
MicroRNAs (miRNAs) have emerged as key regulators of skeletal myogenesis, but our knowledge of the identity of the myogenic miRNAs and their targets remains limited. In this study, we report the identification and characterization of a novel myogenic miRNA, miR-125b. We find that the levels of miR-125b decline during myogenesis and that miR-125b negatively modulates myoblast differentiation in ...
The high recurrence rate remains a major problem that strongly influenced the prognosis of hepatocellular carcinoma (HCC) patients who received hepatectomy. The presence of microvascular invasion (MVI) is regarded as the most important risk factor that contributes to the postoperative recurrence. Our previous study has hinted that serum microRNA-125b (miR-125b) was associated with MVI. The aim ...
BACKGROUND MicroRNAs (miRNAs) are small RNAs that regulate gene expression by targeting mRNA. It was proved that some miRNAs are significantly deregulated in rheumatoid arthritis (RA). MicroRNA-125b negatively regulates expression of TNF-α, which plays a crucial role in RA pathogenesis. The aim of this study was to determine the treatment outcome of patients with early RA based on the expressio...
PURPOSE Circulating microRNAs (miRNA) are emerging as promising diagnostic biomarkers for colorectal cancer, but their usefulness for detecting early colorectal neoplasms remains unclear. This study aimed to identify serum miRNA biomarkers for the identification of patients with early colorectal neoplasms. EXPERIMENTAL DESIGN A cohort of 237 serum samples from 160 patients with early colorect...
Identifying immunocompromised women who are at risk of developing cervical cancer remains a challenge for clinicians. In an effort to identify the role HIV in carcinogenesis, this study evaluated levels normally downregulated oncomirs (miR-21, miR-146a, miR-155, miR-182, and miR-200c) upregulated tumor suppressors (miR-let-7b, miR-125b, miR-143, miR-145, p53 expression) associated with serum li...
Chemokines play a pivotal role in regulating the immune response through a tightly controlled expression. Elevated levels of inflammatory chemokines commonly occur with aging but the mechanism underlying this age-associated change is not fully understood. Here, we report the role of microRNA-125b (miR-125b) in regulating inflammatory CC chemokine 4 (CCL4) expression in human immune cells and it...
miR-125b and miR-100 Are Predictive Biomarkers of Response to Induction Chemotherapy in Osteosarcoma
Osteosarcoma is the most common primary malignancy in bone. Patients who respond poorly to induction chemotherapy are at higher risk of adverse prognosis. The molecular basis for such poor prognosis remains unclear. We investigated miRNA expression in eight open biopsy samples to identify miRNAs predictive of response to induction chemotherapy and thus maybe used for risk stratification therapy...
