Background Tumor mutational burden (TMB), defined as the number of somatic mutations per megabase interrogated genomic sequence, demonstrates predictive biomarker potential for identification patients with cancer most likely to respond immune checkpoint inhibitors. TMB is optimally calculated by whole exome sequencing (WES), but next-generation targeted panels provide estimates in a time-effective and cost-effective manner. However, differences panel size gene coverage, addition underlying...

Abstract Patient-derived xenografts (PDXs) are resected human tumors engrafted into mice for preclinical studies and therapeutic testing. It has been proposed that the mouse host affects tumor evolution during PDX engraftment propagation, affecting accuracy of modeling cancer. Here, we exhaustively analyze copy number alterations (CNAs) in 1,451 matched patient (PT) samples from 509 models. CNA inferences based on DNA sequencing microarray data displayed substantially higher resolution...

The CIITAdel keeps viruses at bay A better understanding of cellular mechanisms involved in viral resistance is needed for the next generation antiviral therapies. Bruchez et al. used a transposon-mediated gene-activation screen to search previously unreported host restriction factors Ebola virus (see Perspective by Wells and Coyne). authors found that transcription factor, major histocompatibility complex class II transactivator (CIITA), induces human cell lines directing expression p41...

We investigated whether breakpoint location can predict matched targeted therapy efficacy.MethodsNSCLCs were analyzed by NGS, target-specific RNA whole-transcriptome sequencing, immunohistochemistry.ResultsIn total, 3787 NSCLC samples analyzed. NGS detected fusions 241, 59, 76 cases, respectively. These...

Abstract Development of candidate cancer treatments is a resource-intensive process, with the research community continuing to investigate options beyond static genomic characterization. Toward this goal, we have established landscapes 536 patient-derived xenograft (PDX) models across 25 types, together mutation, copy number, fusion, transcriptomic profiles, and NCI-MATCH arms. Compared human tumors, PDXs typically higher purity fit dynamic driver events molecular properties via multiple...

Amino acids are transported across the plasma membrane of plant cells by proton-amino acid symports. We report here successful cloning a neutral amino carrier functional complementation. A histidine transport deletion mutant Saccharomyces cerevisiae was transformed with an Arabidopsis thaliana cDNA library constructed in yeast expression vector. Forty transformants, out 10(5), allowed growth on histidine-limiting medium. The acquired ability to grow low shown be strictly dependent protein...

Mannose-binding lectin (MBL) is a key soluble effector of the innate immune system that recognizes pathogen-specific surface glycans. Surprisingly, low-producing MBL genetic variants may predispose children and immunocompromised individuals to infectious diseases are more common than would be expected in human populations. Since certain defense molecules, such as immunoglobulins, can exploited by invasive pathogens, we hypothesized might also enhance infections some circumstances....

Retrotranspositions have independently generated additional YY family members in multiple species. Although Drosophila YY1 [pleiohomeotic (Pho)] its homolog [pleiohomeotic-like (Phol)] redundantly control homeotic gene expression, the regulatory contributions of YY1-homologs not yet been examined other Indeed, targets for mammalian YY2 are completely unknown.
