PromoCell human cardiac microvascular endothelial cells

CircNPHP1 Expression in the Human LV and Cultured ECs Cardiac CircNPHP1 levels are higher in patients with IHD with/without associated T2DM and in cultured <t>endothelial</t> cells (human cardiac <t>microvascular</t> endothelial cells and human umbilical vein endothelial cells) exposed to disease-mimicking conditions, such as hypoxia and hypoxia, combined with increased D-glucose level (High glu). (A) Preliminary screening of circRNAs (identified from predicted networks) in endothelial cells: human cardiac microvascular endothelial cells were cultured in normal conditions, hypoxia (1% Oxygen), and hypoxia-high glucose (High Glu) (25 mmol/L D-glucose) conditions, respectively. After 48 hours, cells were harvested for quantitative real-time polymerase chain reaction (qRT-PCR) for the analysis and validation of indicated circRNAs. RNA expression is relative to normoxia. 18S is used as housekeeping gene; n = 3. Data are expressed as mean ± SEM and were assessed by 1-way analysis of variance with Dunnett's post hoc test. ∗ P < 0.05, ∗∗ P < 0.01, ∗∗∗ P < 0.001, and ns = not significant. CircSTX17 was also tested but the levels were undetectable; hence, it is not included in the plot. CircNPHP1 emerges as an interesting candidate for further exploration and validation. (B) Comparison of expression levels of circNPHP1 and its linear counterpart in different patient groups—RNAseq (LV biopsies, cohort 1). Log-transformed normalized (FPM) counts of circNPHP1 and linear NPHP1 are plotted as a boxplot showing the median and IQR. Comparison between patient groups and calculation of P values was done using the R package Limma. CircNPHP1 is significantly up-regulated in IHD+T2DM compared with IHD and non-IHD ( P < 0.05). Linear NPHP1 is expressed at very low levels and does not change between the different patient groups (IHD [n = 12], IHD+T2DM [n = 11], non-IHD [n = 12]). (C) qRT-PCR of circNPHP1 (left) and linear NPHP1 (right) of LV biopsies (cohort 1) from non-IHD (n = 12), IHD (n = 12), and IHD+T2DM (n = 11), and (D) of LV biopsies (cohort 2) from non-IHD (n = 10), IHD (n = 10), IHD+T2DM (n = 10) of patients. RNA expression is relative to non-IHD; 18S is used as housekeeping gene. Data are expressed as mean ± SEM and were assessed by Kruskal-Wallis test followed by Dunn's post hoc test. ∗ P < 0.05, ∗∗ P < 0.01, ∗∗∗ P < 0.001, and ns = not significant. Abbreviations as in .

CircNPHP1 and Linear NPHP1 Expression in Different Cell Types (A) Single-cell and single-nuclei RNAseq data from healthy donor hearts (human heart atlas ) of NPHP1 gene as log2 transformed counts per million (CPM). Each dot indicates the data point as 1 donor (source: human heart atlas ).
