Single-cell and bulk transcriptome sequencing identifies two epithelial tumor cell states and refines the consensus molecular classification of colorectal cancer
Cell-type annotation scRNA-seq data were filtered to discard low-quality cells and doublets (Supplementary Fig. 1, Extended Data Fig. 1 and Methods). Supervised clustering (Reference Component Analysis v2 (RCA2)) at low resolution grouped cells into 11 major cell types (Extended Data Fig. 1). To identify epithelial cell subtypes, we initially analyzed…
Evaxion Biotech Expands Its EVX-03 DNA Vaccine Program Into Non-Small Cell Lung Cancer
COPENHAGEN, Denmark, June 23, 2022 (GLOBE NEWSWIRE) — Evaxion Biotech A/S (NASDAQ: EVAX) (“Evaxion” or the “Company”), a clinical-stage biotechnology company specializing in the development of AI-driven immunotherapies, today announced that it has selected EVX-03 as the product candidate within its DNA technology platform to target a new indication with…
Single-cell analyses define a continuum of cell state and composition changes in the malignant transformation of polyps to colorectal cancer
Mapping molecular changes across malignant transformation We generated single-cell data for 81 samples collected from eight FAP and seven non-FAP donors (Fig. 1a and Supplementary Tables 1 and 2). For each tissue, we performed matched scATAC-seq and snRNA-seq (10x Genomics). We obtained high-quality single-cell chromatin accessibility profiles for 447,829 cells…
Researchers use nanotechnology to destroy and prevent relapse of solid tumor cancers
Generation and characterization of DCNV-rAd-Ag. a, Generation of DCNVs derived from adenovirus-infected mature dendritic cells. (1) The genes of tumor-specific antigen were genetically engineered into the adenovirus vector. (2) Recombinant adenovirus infected the immature DC2.4 cells to express the modified antigen on the cell surface and stimulate it. (3) Differentiation,…

L-BFGS-B needs finite values of ‘fn’
Let me preface this with the admission that I am not an “expert” here by any means, which means I’m learning as I’m going. I have been tasked with the analysis of high dimensional (spectral) flow cytometry data with 32 parameters (time, six linear parameters (FSC and SSC) and 24…
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…

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…
