Current status and perspectives of non-coding RNA and phase separation interactions.

Phase separation refers to a phenomenon in which different components of a cell collide and fuse with each other to form droplets such that some components are encapsulated within the droplet and some are blocked outside. It is prevalent in eukaryotic cells and is closely related to genome assembly and transcriptional regulation, enabling multiple biological functions. With the development of high-throughput sequencing technologies, several non-coding RNAs (ncRNAs) have been shown to play an important role in epigenetic regulation of gene expression in addition to their roles at the transcriptional and post-transcriptional levels.

can predict the poor prognosis of clear cell renal cell carcinoma.

Purpose: Clear cell renal cell carcinoma (ccRCC) is one of the most common malignancies of the urinary system. This study was conducted to discover a new target that can predict the prognosis and promote the treatment of ccRCC.

Methods: The raw data were downloaded from the TCGA database, and the predictive value of for various clinicopathological features was verified in the following analysis.

Fast and Ultrasensitive Visual Detection of Exosomes in Body Fluids for Point-of-Care Disease Diagnosis.

Fast detection of low-concentration exosomes in body fluids is of great significance in understanding the pathogenesis and disease diagnosis but is quite a challenging work due to the complex matrix, tedious pretreatment, and relatively poor sensitivity without the aid of instruments. In this work, by simply using a filter membrane to enrich the exosomes at low concentrations and the use of CuS nanoparticles as labels, we were able to detect exosomes at concentrations as low as 2 × 10 particles/μL in a complex matrix by the naked eye. Due to its high sensitivity, specificity, and simplicity, it can be used for the diagnosis of direct prostate cancer via a 5 mL urine sample within 2 h without the use of any instrument.
