Background Baseline clinical variables are prognostic for overall survival (OS) in patients with castration-resistant prostate cancer (CRPC). Their prognostic and predictive value with agents targeting bone metastases, such as radium-223, is not established. Patients and methods The radium-223 ALSYMPCA trial enrolled patients with CRPC and symptomatic bone metastases. Prognostic potential of ...
BACKGROUND The mechanism for inactivation of positive regulatory domain containing I (PRDM1), a newly identified tumour suppressor gene in extranodal NK/T-cell lymphoma, nasal type (EN-NK/T-NT) has not been well defined. The aim of the present study was to investigate the expression of PRDM1 in EN-NK/T-NT and analyse its downregulation by miRNAs. METHODS PRDM1 and miRNA expression were evalua...
objective: micrornas (mirna) are a class of non-coding rnas which play key roles in post-transcriptional gene regulation. previous studies indicate that mirnas are dysregulated in patients with multiple sclerosis (ms). th17 and regulatory t (treg) cells are two subsets of cd4+ t-cells which have critical functions in the onset and progression of ms. the current study seeks to distinguish fluctu...
MicroRNAs (miRs) are a large class of small regulatory RNAs that function as nodes of signaling networks. This implicates that miRs expression has to be finely tuned, as observed during cell cycle progression. Here, using an expression profiling approach, we provide evidence that the CDK inhibitor p27Kip1 regulates miRs expression following cell cycle exit. By using wild type and p27KO cells ha...
Objective To investigate the effects of microRNA-223 on morphine analgesic tolerance by targeting NLRP3 in a rat model of neuropathic pain. Methods Our study selected 100 clean grade healthy Sprague-Dawley adult male rats weighing 200 to 250 g. After establishment of a rat model of chronic constriction injury, these rats were divided into 10 groups (10 rats in each group): the normal control, s...
زمینه و هدف: در ایران، در نواحی خاصی از شهرستان رامسر، مناطقی وجود دارند که سطح پرتوزایی طبیعی در آن ها بسیار بالا می باشد. در واقع، سطح پرتوزایی زمینه ای در برخی مناطق رامسر، به عنوان یکی از بالاترین سطوح شناخته شده در جهان می باشد. پرتوزایی زمینه ای بالا در این مناطق از رامسر، به طور اولیه، به علت حضور مقادیربسیار بالا از رادیم 226 و فرآورده های ناشی از واپاشی آن (مانند گاز رادان) است که به و...
Radium-223 is a first-in-class alpha particle-emitting radiopharmaceutical approved for the treatment of bone metastatic castration-resistant prostate cancer. Radium-223 is administered intravenously with no requirement for complex shielding and specifically targets areas of bone metastasis. In a randomized placebo-controlled Phase III study, treatment with radium-223 was shown to improve overa...
The aims of the present study were to examine the potential role of microRNA‑233‑3p (miR)‑223‑3p in the tumorigenesis of hepatocellular carcinoma (HCC), and to investigate its diagnostic accuracy and potential molecular mechanisms. The expression data of miR‑223‑3p in HCC were obtained from the Gene Expression Omnibus (GEO). Data for the precursor miR‑223 were obtained from The Cancer Genome At...
BACKGROUND In Alpharadin in Symptomatic Prostate Cancer (ALSYMPCA) trial, radium-223 versus placebo prolonged overall survival with favorable safety in castration-resistant prostate cancer patients with symptomatic bone metastases. Long-term radium-223 monitoring underlies a comprehensive safety and risk/benefit assessment. OBJECTIVE To report updated ALSYMPCA safety, including long-term safe...
BACKGROUND/AIMS Over the past decade, heat shock protein 90 (Hsp90) has emerged as a potential therapeutic target for cancer. However, the molecular mechanisms of down-regulation Hsp90 expression in osteosarcoma are incompletely understood. To develop potential therapy targeting Heat shock protein 90B1 (Hsp90B1), we studied the roles of miR- 223 in the proliferation and apoptosis of human osteo...
