Phenotypic characterization and analysis of complete genomes of two distinct strains of the proposed species “L. swaminathanii”

Since 2010, there have been multiple new species added to the Listeria genus, many originally isolated from natural environments16. This paper describes the genotypic and phenotypic characterization of two new Listeria isolates obtained from soil samples collected in the Great Smoky Mountains National Park along the North Carolina-Tennessee border17. Evaluation…

Innovative site-specific anti-HER2 antibody-drug conjugate

Introduction Antibody-drug conjugates (ADCs) have been studied for decades as a promising cancer treatment. As compared to conventional chemotherapy, ADCs have a larger therapeutic window because of their ability to target antigen-expressing tumor cells.1 As ADC drug development technology continues to evolve, several ADC drugs are being introduced to the…

Requirement of Xk and Vps13a for the P2X7-mediated phospholipid scrambling and cell lysis in mouse T cells

Significance The extracellular concentration of adenosine triphosphate (ATP) reaches several hundred micromoles in the inflamed tissues or tumor environment. A high concentration of ATP activates P2X7, a purinergic receptor, and induces the formation of a nonselective cation channel, accompanied by reversible phosphatidylserine (PtdSer) exposure, leading to cell lysis. Here, we…

In-Depth Analysis of Bacillus anthracis 16S rRNA Genes and Transcripts Reveals Intra- and Intergenomic Diversity and Facilitates Anthrax Detection

Various ratios of 16S-BA/BC-alleles constitute possible explanations for differences in FISH signals of cells of diverse B. anthracis strains (Fig. 1). Indeed, we found a significant correlation between 16S-BA/BC-allele ratios in sequenced genomes and mean intensities of the Cy3 FISH signals targeting the16S-BA-allele (tested with the cor.test function in R, Pearson’s…

A cell-based phenotypic library selection and screening approach for the de novo discovery of novel functional chimeric antigen receptors

Cell lines and culture Unless stated otherwise, all tumor target cell lines were sourced from the ATCC via LGC Standards. Human endogenous mesothelin (MSLN)-positive target cell lines H-226 (lung carcinoma, MSLN+, ATCC® CRL-5826™) and AsPC-1 (ATCC CRL-1682), and MSLN-negative Raji control cells (ATCC CCL-86) were cultured in RPMI-1640 Glutamax (Life Technologies,…

Sod1 integrates oxygen availability to redox regulate NADPH production and the thiol redoxome

Significance Cu/Zn superoxide dismutase (Sod1) is a key antioxidant enzyme, and its importance is underscored by the fact that its ablation in cell and animal models results in oxidative stress; metabolic defects; and reductions in cell proliferation, viability, and lifespan. Curiously, Sod1 detoxifies superoxide radicals (O2•−) in a manner that…

p57 Suppresses the Pluripotency and Proliferation of Mouse Embryonic Stem Cells by Positively Regulating p53 Activation

Embryonic stem cells (ESCs) are pluripotent stem cells that have indefinite self-renewal capacities under appropriate culture conditions in vitro. The pluripotency maintenance and proliferation of these cells are delicately governed by the concert effect of a complex transcriptional regulatory network. Herein, we discovered that p57Kip2 (p57), a cyclin-dependent kinase inhibitor…

Establishment of sunitinib-resistant CDX model of ccRCC

Introduction Renal cell carcinoma (RCC) accounts for approximately 2–3% of all malignant tumors, and its prevalence is rising. Metastatic RCC accounts for 25–30% of all RCC cases, and has an exceedingly poor prognosis.1 In 2020, among approximately 430,000 newly discovered cases of RCC, 179,000 died.2 Clear cell renal cell carcinoma…

Single-cell delineation of lineage and genetic identity in the mouse brain

STICR lentiviral library preparation and validation We synthesized a high-complexity lentivirus barcode library that encodes approximately 60–70 million distinct oligonucleotide RNA sequences (STICR barcodes). STICR barcodes comprised three distinct oligonucleotide fragments cloned sequentially into a multicloning site within the 3′ UTR of an enhanced green fluorescent protein (eGFP) transgene under…

P. aeruginosa isolated from patients with aural infections

Introduction Aural infections are one of the most common diseases of the head and neck and are predominantly caused by bacterial infections of the ear canal. Several studies from different countries have reported that Pseudomonas aeruginosa is the most common pathogen isolated from ear canal secretions, followed by Staphylococcus aureus.1…

Emergence of the Coexistence of mcr-1, blaNDM-5, and blaCTX-M-55 in Kl

Introduction Klebsiella pneumoniae (K. pneumoniae) is an opportunistic pathogen and the leading cause of healthcare-associated infections.1 Multidrug-resistant (MDR) K. pneumoniae isolates are rapidly spreading, thus limiting the choice of antimicrobial agents for empiric treatment of infections caused by these microorganisms; hence, this is a public health challenge.2 Polymyxins are last-resort…

Plasmid-Encoded VIM-2-pProducing Pseudomonas stutzeri | IDR

Introduction Pseudomonas stutzeri is an aerobic, nonfermenting, active, Gram-negative oxidase-positive bacterium with unique colony morphology.1,2 Burri and Stutzer first described it in 1985,3 and the specific metabolic properties, such as denitrification, degradation of aromatic compounds, and nitrogen fixation, distinguish it from other pseudomonads species.2,4 Historically, P. stutzeri was not commonly…
