Cell-free DNA for the detection of emerging treatment failure in relapsed/ refractory multiple myeloma

Interrogation of cell-free DNA (cfDNA) represents an emerging approach to non-invasively estimate disease burden in multiple myeloma (MM). Here, we examined low-pass whole genome sequencing (LPWGS) of cfDNA for its predictive value in relapsed/ refractory MM (RRMM). We observed that cfDNA positivity, defined as ≥10% tumor fraction by LPWGS, was…

Process Development for the Production and Purification of Adeno-Associated Virus (AAV)2 Vector using Baculovirus-Insect Cell Culture System

In this protocol, AAV2 vector is produced by co-culturing Spodoptera frugiperda (Sf9) insect cells with baculovirus (BV)-AAV2-green fluorescent protein (GFP) or therapeutic gene and BV-AAV2-rep-cap infected Sf9 cells in suspension culture. AAV particles are released from the cells using detergent, clarified, purified by affinity column chromatography, and concentrated by tangential…

Identification of a regulatory pathway inhibiting adipogenesis via RSPO2

Integration of APC scRNA-seq data reveals heterogeneity of adipocyte progenitor cells In a previous study9, we defined Lin−Sca1+CD142+ APCs as adipogenesis regulatory (Areg) cells and demonstrated that these cells are both refractory toward adipogenesis and control adipocyte formation of APCs through paracrine signaling. In contrast, Merrick et. al.4 observed that Lin−CD142+ cells…

Ttc30a affects tubulin modifications in a model for ciliary chondrodysplasia with polycystic kidney disease

Significance Cilia are tubulin-based cellular appendages, and their dysfunction has been linked to a variety of genetic diseases. Ciliary chondrodysplasia is one such condition that can co-occur with cystic kidney disease and other organ manifestations. We modeled skeletal ciliopathies by mutating two established disease genes in Xenopus tropicalis frogs. Bioinformatic…

CRISPR-Based Therapeutics Blaze an In Vivo Path to the Clinic

Therapeutic applications of genome editing were envisioned at least as early as the mid-1990s, when the first sequence-specific genome editing technologies emerged. Initially, such applications were considered distant prospects, but by 2012, they suddenly seemed near to hand. It was at that time that CRISPR technologies emerged. CRISPR, which stands…

High-purity production and precise editing of DNA base editing ribonucleoproteins

Abstract Ribonucleoprotein (RNP) complex–mediated base editing is expected to be greatly beneficial because of its reduced off-target effects compared to plasmid- or viral vector–mediated gene editing, especially in therapeutic applications. However, production of recombinant cytosine base editors (CBEs) or adenine base editors (ABEs) with ample yield and high purity in…

Multiform antimicrobial resistance from a metabolic mutation

Abstract A critical challenge for microbiology and medicine is how to cure infections by bacteria that survive antibiotic treatment by persistence or tolerance. Seeking mechanisms behind such high survival, we developed a forward-genetic method for efficient isolation of high-survival mutants in any culturable bacterial species. We found that perturbation of…

Pericentromeric noncoding RNA changes DNA binding of CTCF and inflammatory gene expression in senescence and cancer

Significance During the aging process, senescent cells secrete inflammatory factors, causing various age-related pathologies. Thus, controlling the senescence-associated secretory phenotype (SASP) can tremendously benefit human health. Although SASP seems to be induced by the alteration of chromosomal organization, its underlying mechanism remains unclear. Here, it has been revealed that noncoding…
