Antibodies Sentences Resources Primary antibodies towards human ACE2 were the polyclonal rabbit IgG antibody HPA000288, RRID: AB_1078160, (Atlas Antibodies AB, Bromma, Sweden) and monoclonal mouse IgG antibody MAB933, RRID: AB_2223153, (R&D Systems, Minneapolis, MN). ACE2 the polyclonaldetected: (Atlas Antibodies Cat# HPA000288, RRID:AB_1078160)mouse IgGdetected: (R and D Systems Cat# MAB933, RRID:AB_2223153)The membranes were incubated with two different primary antibodies towards ACE2: HPA000288 (Atlas Antibodies AB) and MAB933 (R&D Systems). ACE2suggested: (Sigma-Aldrich Cat# HPA000288, RRID:AB_1078160)HRP-conjugated antibodies were used as secondary antibodies (Swine anti-rabbit 1:3000 anti-rabbitsuggested: NoneData availability: High-resolution images corresponding to immunohistochemically stained TMA cores from three individuals in 44 different tissue types are readily available in version 19.3 of the Human Protein Atlas (https://www.proteinatlas.org), using both the HPA000288 antibody and the MAB933 antibody. MAB933suggested: NoneSoftware and Algorithms Sentences Resources Data sources: RNA expression data from HPA(Uhlen et al., 2015), GTEx(Keen & Moore, 2015), FANTOM5(Yu et al., 2015) as well as the normalized RNA expression dataset were retrieved from the HPA database (http://www.proteinatlas.org). http://www.proteinatlas.orgsuggested: (HPA, RRID:SCR_006710)The lung scRNA-seq data (gene raw counts) were downloaded from the Gene Expression Omnibus (GEO) (https://www.ncbi.nlm.nih.gov/geo/) database under the series numbers: GSE130148 (Viera Braga, 2019), GSE134355 (Han et al., 2020) (samples: GSM4008628, GSM4008629, GSM4008630, GSM4008631, GSM4008632 and GSM4008633) and GSE122960 (Reyfman et al., 2019) (samples: GSM3489182, GSM3489185, GSM3489187, GSM3489189, GSM3489191, GSM3489193, GSM3489195 and GSM3489197). Gene Expression Omnibussuggested: (Gene Expression Omnibus (GEO, RRID:SCR_005012)ACE2 mass spectrometry-based expression among different tissues was assessed by retrieving data in two proteomics databases: Protein abundance database (PaxDB) (Wang et al, 2015) and ProteomicsDB (Schmidt et al, 2018). ProteomicsDBsuggested: (ProteomicsDB, RRID:SCR_015562)The gene expression data were normalized using Seurat default settings, and cell clustering was based on the 5,000 most highly variable genes. Seuratsuggested: (SEURAT, RRID:SCR_007322)Results from OddPub: We did not detect open data. We also did not detect open code. Researchers are encouraged to share open data when possible (see Nature blog).
Results from LimitationRecognizer: We detected the following sentences addressing limitations in the study:Technical limitations related to the different techniques used for tissue dissociation result in a lower amount of starting material for sequencing. The proportions of different cell types analyzed within a tissue may be biased and not reflect the true biological proportions, due to some cell types being less tolerant for dissociation. It may also lead to the “drop out” phenomenon, where a gene showing high expression levels in a certain cell lacks expression in other cells corresponding to the same cell type (Haque et al, 2017). Other limitations include challenges related to interpretation and analysis of the complex datasets, involving quality control for removing low-quality scRNA-seq data, normalization and manual annotation of cell clusters. It is also important to note that scRNA-seq data generated by different methods or platforms may lead to batch effects. To be able to compare expression data based on scRNA-seq datasets from different sources across diverse cell and tissue types in a consistent way, the global Human Cell Atlas effort promotes standardization of methods and strategies used for both scRNA-seq protocols and data analysis (Ding et al, 2020; Mereu, 2020). Further advances in this emerging field are likely to lead to more refined maps on the single cell transcriptomes of different human tissues and organs in health and disease. As various methods for mRNA and protein detection have different advantages and disadvantages, an integrated omics approach combi...
