Project description:Small non-coding RNA profiling of urine exosomal total RNA from patients with or without prostate cancer were performed using Affymetrix GeneChip miRNA 4.0 to identify small non-coding RNA profile that can be used for prostate cancer diagnosis.

Project description:Prostate cancer is one of the major cancers that seriously affect men's health. The low specificity of prostate-specific antigen (PSA) for prostate cancer has resulted in the overdiagnosis and subsequent overtreatment of clinically indolent tumors. There is an urgent need for noninvasive and easy diagnostic assays to help evaluate whether a prostate biopsy is warranted. Many non-coding RNAs (eg, microRNAs, long non-coding RNAs, circular RNAs) have been reported to play key roles in prostate cancer progression, showing great potential to impact cancer diagnostics and therapies. Remarkably, exosomes secreted by cells into body fluids contain molecules that reflect the disease information, and urinary exosomes could be used to detect prostate cancer as a new type of liquid biopsies. Non-coding RNAs are enriched and stable in exosomes. We performed high-throughput sequencing on urine-derived exosomes of 11 patients with high-grade (Gleason score 7 or greater) prostate cancer and 11 patients with benign prostatic hyperplasia to screen differentially expressed non-coding RNAs.
Project description:We aimed to identify urinary exosomal ncRNAs as novel biomarkers for diagnosis of Chronic Kidney Disease (CKD) for this, we examined 15 exosomal ncRNA profiles in urine samples from CKD patients from four different stages (I, II, III and IV) and compared them to 10 healthy controls. We identified a significant number of novel, differentially expressed ncRNAs in CKD patients compared to healthy, which might be employed as early diagnostic markers in CKD in the future.
Project description:Urinary exosomal miRNA profiling was conducted in urinary exosomes obtained from 8 healthy controls (C), 8 patients with type II diabetes (T2D) and 8 patients with type II diabetic nephropathy (DN) using Agilent´s miRNA microarrays.
Project description:Acute rejection prediction classifiers were successfully constructed through expression profiling of a total of 개수 urinary exosomal microRNAs in 108 kidney transplant recipients.
Project description:Vitamin D, a hormone that acts through the nuclear vitamin D receptor (VDR), upregulates anti-tumorigenic microRNA in prostate epithelium. This may contribute to the lower levels of aggressive prostate cancer (PCa) in patients with high serum vitamin D. Expression of other small non-coding RNAs (ncRNAs) in prostate epithelium and their potential regulation by vitamin D are uncharacterized. Laser capture microdissection (LCM) followed by small-RNA sequencing was used to identify ncRNA in the prostate epithelium of tissues from a vitamin D-supplementation trial. We compared the expression profiles to small-RNA sequencing data from primary prostate epithelial cells and publically-available benign whole prostate. Application of LCM to isolate epithelium promoted sample homogeneity and captured more diversity in ncRNA species. An abundance of PIWI-interacting RNAs (piRNAs) was detected in normal prostate epithelium, which increased under high vitamin D conditions.
