Adult_Mammary glands_10x RNAseq
Description
For the primary mammary gland scRNA-seq, Wild type (C57BL/6) mice were used. After preparation of primary mammary single cell suspension, we specifically sorted 2000 Procr+ MaSCs (CD31-, CD45-, Ter119-, CD24+, CD29hi) and also enrich 20000 mammary epithelial cells (CD31-, CD45-, Ter119-, CD24+), 30000 mammary immune cells (CD45+) and enrich 10000 stromal cells which contain endothelial cells and mesenchymal cells (CD45-, Ter119-, CD24-) and resuspended total cells at a density of 1000 cells per μl. And then 13,000 single cells were loaded for 10x single cell genomics RNA seq. Filtering, alignment to the mm10 database and unique molecular identifier (UMI)-collapsing were performed using the Cell Ranger (v2) pipeline with default mapping arguments (10′ Genomics). Cell filtering: we used the Seurat 3 R package for data integration, analysis and visualization. To create Seurat object, genes which expressed in at least 3 cells and cells which had at least 200 detected genes, 1500 detected UMIs and no more than 5000 detected UMIs were selected. PC selection: the differentially expressed genes were found by “vst” method and the top 2000 differentially expressed genes were selected for PCA analysis. PCs selection was based on an elbow plot. 20 PCs were used for analysis. Dimensional reduction, cell clustering and data

Description
For the primary mammary gland scRNA-seq, Wild type (C57BL/6) mice were used. After preparation of primary mammary single cell suspension, we enriched 2000 Procr+ basal cells, 30000 mammary epithelial cells and 30000 mammary immune cells and resuspended total cells at a density of 1000 cells per μl. And then 13,000 single cells were loaded for 10x single cell genomics RNA seq.

Screening and identification of immunological signatures in cord blood of HIV-exposed uninfected infants
Description
In the course of immune development, HIV-exposed uninfected (HEU) infants exhibit abnormal immune function and higher infectious morbidity compared to HIV-unexposed uninfected (HUU) infants. Yet functional phenotypes and the regulators associated with in-utero HIV exposure remain largely obscure. Herein, we utilized flow cytometry and RNA-seq technologies to establish the immune and transcriptional profiling in cord blood from 9 HEU mother-infant pairs and 24 HUU pairs. On top of that, we compared the cord blood dataset with the maternal venous blood dataset to characterize the unique effects induced by in-utero HIV exposure. Flow cytometry immunophenotyping revealed a significant decrease in the level of B lymphocyte subsets in HEU cord blood compared to HUU cord blood. Expression profiling-based assessment of cell abundance indicated a marked reduction in naive B cells in HEU cord blood, supporting the altered composition of B lymphocyte subsets in HEU infants. Functional enrichment results demonstrated a propensity for suppressed innate immune responses and impaired immune regulatory function of B cells in HEU cord blood. Additionally, through a combination of differential expression analysis, co-expression network analysis, and feature selection analysis, we identified an immunologically significant HEU-related signature. This 4-gene signature could effectively assess B cell levels in cord blood, enabling discrimination between HEU and HUU infants. This study provides the first transcriptomic characterization of HEU cord blood compared to maternal venous blood and establishes a 4-gene-based classifier for predicting immunological abnormalities in HEU infants. These findings hold promise for uncovering new mechanisms underlying abnormal immune system development in infants due to in-utero HIV exposure.

Metabolic characterization of sphere-derived prostate cancer stem cells
Description
Alteration of cell metabolism is one of the essential characteristics of tumor growth. Cancer stem cells (CSCs) are the initiating cells of tumorigenesis, proliferation, recurrence, and other processes, and play an important role in therapeutic resistance and metastasis. Thus, identification of the metabolic profiles in prostate cancer stem cells (PCSCs) is critical to understanding prostate cancer progression. Here, using untargeted metabolomics and lipidomics methods, we showed distinct metabolic differences between prostate cancer cells and PCSCs. We obtained DU145 spheres by ultralow-attached culture in sphere conditional medium. We use serum-induced sphere (adherent state) as control (Adh), and generation 2 (G2) and generation 3 (G3) of spheres as experimental groups to study the metabolic changes between prostate cancer cells and cancer stem cells.
