Blood glucose levels are tightly controlled by the coordinated actions of hormone-producing endocrine cells that reside in pancreatic islets. Islet cell malfunction underlies diabetes development and progression. Due to the cellular heterogeneity within islets, it has been challenging to uncover ...

Higher eukaryotic genomes are bound by a large number of coding and non-coding RNAs, but approaches to comprehensively map the identity and binding sites of these RNAs are lacking. Here UCSD researchers report a method to capture in situ global ...
Read More »New tool to map RNA-DNA interactions could help researchers translate gene sequences into functions
Bioengineers at the University of California San Diego have developed a new tool to identify interactions between RNA and DNA molecules. The tool, called MARGI (Mapping RNA Genome Interactions), is the first technology that’s capable of providing a full account ...

from Spectrum.com by Ann Griswold – A new tool provides speedy analysis of gene expression patterns in individual neurons from postmortem brain tissue. Researchers have used the method to compare the genetic signatures of more than 3,000 neurons from distant ...
Read More »Assessment of single cell RNA-seq normalization methods
UCSD researchers have assessed the performance of seven normalization methods for single cell RNA-seq using data generated from dilution of RNA samples. Their analyses showed that methods considering spike-in ERCC RNA molecules significantly outperformed those not considering ERCCs. This work ...
