Two recent articles suggest that CRISPR/Cas9 can cause mutations in the p53 pathway, irrespective of the target sequence of the guide RNA. The data are extremely interesting since they raise the issue of unpredictable off-target effects that are not directly introduced by the CRISPR/Cas9 complex but rather selected during the genome manipulation process. A thorough analysis of the genomic integrity of cells genetically manipulated with CRISPR is, therefore, the key to successful use of the technology, as described in https://perkinelmer-appliedgenomics....w-crispr-cas9/.

NGS has revolutionized clinical microbiology by offering new ways to identify and surveil pathogens without prior knowledge of the target. One popular approach is 16S rRNA and ITS amplicon sequencing, which targets specific microbial markers. But studies are increasingly incorporating shotgun metagenomics, a technique that sequences all DNA from a sample without targeting specific microbial markers. This approach allows more detailed taxonomic classification, detection...10-30-2026, 06:46 AM -
Tumors contain complex mixtures of cell populations that evolve in response to treatment and host-specific factors. Tissue biopsies provide only static snapshots of a tumor’s state. But what if we could follow that evolution over time using a minimally invasive technique?
Liquid biopsies can detect tumor-derived material circulating in the bloodstream, providing a way to study treatment response, detect emerging resistance, and discover new biomarkers. Circulating...10-14-2026, 09:55 AM
