Article Title: Cnot1, Cnot2, and Cnot3 Maintain Mouse and Human ESC Identity and Inhibit Extraembryonic Differentiation

doi: 10.1002/stem.1070

Figure Lengend Snippet: The Cnot genes maintain self-renewal by repressing early trophectoderm (TE) transcription factors. (A): Cnot1, Cnot2, and Cnot3 knockdown did not immediately affect known self-renewal factors and pathways. Oct4GiP cells were transfected with control-siRNA (Control), Cnot1-siRNA1 (Cnot1-KD), Cnot2-siRNA2 (Cnot2-KD), or Cnot3-siRNA2 (Cnot3-KD) in M15 medium. Cells were collected 48 hours after transfection, and total Stat3, Smad1, b-Catenin as well as phospho-Stat3, phospho-Smad1, phosphor-b-Catenin, Oct4, and Nanog levels were determined by Western blot. Starved: control-transfected ESCs cultured in serum-free and LIF-free medium for additional 4 hours. (B): Comparing gene expression changes caused by perturbations of known self-renewal factors: Cnot1, 2, and 3 silencing induced similar changes to those of Oct4 or Sox2 silencing. Pearson's correlation coefficients were calculated between microarray datasets and depicted in a heatmap. The self-renewal factors were clustered by unsupervised hierarchical clustering based on the correlation coefficients. Microarray datasets used for this plot are listed in Supporting Information Table 2. (C): Cnot2 or Cnot3 overexpression cannot rescue Oct4 or Sox2 silencing-induced differentiation. Oct4GiP cells and Oct4GiP cells overexpressing Cnot2 (Cnot2-Rescue, same as in Fig. 1C) or Cnot3 (Cnot3-Rescue, same as in Fig. 1C) were transfected with control, Oct4 (Oct4-KD), or Sox2 (Sox2-KD) siRNAs, and the % differentiation was determined by the Oct4GiP reporter assay. (D): Cnot1, Cnot2, and Cnot3 knockdown induced TE differentiation in the presence of sustained Oct4 expression. ZHBTc4 cells that constitu-tively express Oct4 at the normal level from a Tet-Off promoter were transfected with control or Cnot1-siRNA1 (Cnot1-KD), Cnot2-siRNA2 (Cnot2-KD), Cnot3-siRNA2 (Cnot3-KD), and the expression of TE markers Cdx2 and Gata3 was determined by qRT-PCR after 4 days. (E): Cdx2 deletion partially rescued Cnot1, Cnot2, and Cnot3 silencing-induced differentiation. Oct4GiP (WT) or dKO23-5 (Cdx2-/- ) cells were transfected with Control-siRNA (Control), Cnot1-siRNA1 (Cnot1-KD), Cnot2-siRNA2 (Cnot2-KD), or Cnot3-siRNA2 (Cnot3-KD), and the expression of lineage markers was determined by qRT-PCR 96-hour after transfection. Abbreviations: ESC, embryonic stem cell; KD, Knockdown; WT, wild type.

Article Title: Cnot1, Cnot2, and Cnot3 Maintain Mouse and Human ESC Identity and Inhibit Extraembryonic Differentiation

doi: 10.1002/stem.1070

Figure Lengend Snippet: Silencing Cnot1, Cnot2, or Cnot3 led to mouse embryonic stem cell (ESC) differentiation. (A): Silencing Cnot1, Cnot2, or Cnot3 resulted in ESC differentiation based on the Oct4GiP reporter assay. Oct4GiP ESCs were transfected with indicated siRNAs (two different siR NAs for each CCr4-Not complex gene) in M15 medium and cultured for 4 days. The percentage of differentiated cells (% differentiation) was determined by measuring the percentage of green fluorescent protein-negative cells by fluorescence-activated cell sorting (FACS) at the end of the culture. (B): Expression of siRNA-resistant Cnot2 or Cnot3 rescued the differentiation caused by Cnot2 or Cnot3 knockdown, respectively. Oct4GiP cells or Oct4GiP cells expressing siRNA-resistant Cnot2 (Cnot2-Rescue) or Cnot3 (Cnot3-Rescue) were transfected with Control, Cnot1-siRNA1, Cnot2-siRNA2, or Cnot3-siRNA2, and the percentage of differentiated cells was determined by the Oct4GiP reporter assays. Note that Cnot2-Rescue cells were not able to rescue the differentiation caused by Cnot1 or Cnot3 silencing, and Cnot3-Rescue cells were not able to rescue Cnot1 or Cnot2 silencing. ***, p < .001. (C): Silencing Cnot1, Cnot2, or Cnot3 resulted in morphological changes and loss of alkaline phosphatase (AP) staining in ESCs. Oct4GiP cells were transfected with the indicated siRNAs and cultured in the M15 medium. Cells were stained with the AP staining kit and imaged 4 days after transfection. (D): Cnot1, Cnot2, or Cnot3 silencing led to downregulation of ESC marker and upregulation of differentiation markers. Oct4GiP cells were transfected with the indicated siRNAs and cultured in the M15 medium. Cells were harvested for quantitative real-time PCR (qRT-PCR) analysis 4 days after transfection. ESC marker: Oct4; differentiation markers: Cdx2, Eomes, Gata3, Hand1, and Krt8. (E): Cnot1, Cnot2, or Cnot3 silencing reduced cell proliferation or viability in 2i medium. Oct4GiP cells were transfected with control-siRNA (Control), Cnot1-siRNA1 (Cnot1-KD), Cnot2-siRNA2 (Cnot2-KD), or Cnot3-siRNA2 (Cnot3-KD) and cul tured in 2i medium. Cell numbers were counted by FACS 4 days after transfection and normalized to control-transfected cells. (F): Cnot1, Cnot2, or Cnot3 silencing led to differentiation in 2i medium. Oct4GiP cells were transfected with indicated siRNAs and cultured in 2i medium. Cells were harvested for qRT-PCR analysis 4 days after transfection. (G): Expression of C-terminally HA-tagged Cnot2 (Cnot2-HA) in E14Tg2a cells. Expression of the exogenous Cnot2-HA was detected in Western blot with the HA-antibody, and Ran was used as a loading control. Expression of total (endogenous and exogenous) Cnot2 was determined by qPCR in wild-type E14Tg2a (E14) and Cnot2-HA expressing cells. The expression of the Cnot2-HA was estimated to be ∼2-fold of the endogenous Cnot2 on the mRNA level. (H): Identification of Cnot1 and Cnot3 in Cnot2-HA immunoprecipitation. HA-pull-down was carried out in E14Tg2a cells expressing Cnot2-HA. The presence of Cnot1, Cnot2-HA, and Cnot3 in the total lysate and pull-down sample (HA-beads) were detected by Western blot. Note that Oct4 was not detected in the pull down sample. As a negative control, protein-A beads were used in an independent pull-down. Abbreviations: HA, hemagglutinin; IP, immunoprecipitation; KD, knockdown.

doi: 10.1002/stem.1070

Figure Lengend Snippet: Cnot1, Cnot2, and Cnot3 are required for human embryonic stem cell (ESC) self-renewal. (A): Cnot1, Cnot2, and Cnot3 were down-regulated during human ESC differentiation. H1 human ESCs were differentiated for 7 days using 100 ng/ml human recombinant BMP4. The expression levels of Cnot1, Cnot2, and Cnot3 as well as Oct4 and differentiation markers Cdx2 and Hand1 were determined by quantitative realtime PCR (qRT-PCR). (B): Silencing of Cnot1, Cnot2, or Cnot3 led to morphological changes of human ESCs. H1 cells were imaged 6 days after transfection. Phase-contrast images highlight the undifferentiated morphology of human ESCs in the lipids-only transfected cells (mock) versus the differentiated phenotype in the Cnot1, Cnot2, or Cnot3 siRNA transfected cells. (C): Silencing of the Cnot genes led to upregulation of the Cdx2 and Gata3 proteins. H1 cells were transfected with lipids-only (mock), Oct4, Cnot2, or Cnot3 siRNAs. Cells were fixed and stained for Cdx2 or Gata3 expression by immunofluorescence staining 6 days after transfection. (D): Silencing of the Cnot genes led to downregulation of the ESC marker and upregulation of the extraembryonic markers. H1 cells were harvested 6 days after transfection and marker expression was determined by qRT-PCR. Abbreviations: BMP, bone morphogenetic protein; DAPI, 4′-6-diamidino-2-phenylindole.

Figure Lengend Snippet: Figure 6. Defective Proteostasis in the Pancreas of Ccpg1 Hypomorphic Mice (A and B) Whole pancreata from littermate 6-week-old WT (+/+) or Ccpg1 hypomorphic (GT/GT) mice were immunoblotted for CCPG1 or subjected to RNA extraction and qRT-PCR for Ccpg1 (n = 3 pairs, ± SEM, ***p < 0.001, two-tailed t test). (C and D) Fifty mg of whole pancreata from littermate pairs of 6-week-old WT and Ccpg1 hypomorphic mice were homogenized in SDS. Insoluble protein was pelleted, washed and extracted in 8 M urea +10 mM DTT. Pellet samples were normalized according to protein concentration in the soluble fraction and subjected to label-free LC-MS/MS quantification. A median absolute deviation analysis is presented as a heatmap here to show species changing significantly between pairs of mice (pairs joined by connecting brackets). Secretory enzymes are in red, ER luminal chaperones/oxidoreductases are in blue. (E and F) Detergent soluble and insoluble samples prepared as above were immunoblotted and ratios of insoluble to soluble protein species obtained via densitometry (n = 3 pairs, ± SEM, *p < 0.05, **p < 0.01, ***p < 0.001, two-tailed t tests).

Polarized acinar cells secrete condensed enzyme (zymogen) granules into ducts from their apical stores. These enzymes are initially synthesized in the expansive rough ER (rER), which occupies the basolateral regions of the cell. (B) CARS imaging or immunohistochemical staining for the ER (protein disulfide isomerase, PDI) in pancreatic tissue from 6-week-old littermate WT (+/+) or Ccpg1 hypomorphic (GT/GT) mice. Punctate CARS signals indicate protein or lipid inclusions. Scale bars, 20 mm. (C) Transmission electron microscopy (TEM) of pancreata from 6-week-old littermate pairs. Scale bar, 5 mm. Analysis of percent cytosolic area occupied by osmophilic protein granules was performed in ImageJ (n = 4 pairs, ± SEM, *p < 0.05, two-tailed t test). (D) High magnification TEM of a Ccpg1 hypomorphic mouse reveals that the rER is distended and many supernumerary inclusions are in fact intracisternal granule-like structures (arrows in zoomed inset).

Article Title: Glomerular basement membrane deposition of collagen α1(III) in Alport glomeruli by mesangial filopodia injures podocytes via aberrant signaling through DDR1 and integrin α2β1.

doi: 10.1002/path.5969

Figure Lengend Snippet: Figure 1. Collagen α1(III) is expressed in the glomerular basement membrane in Alport mice. (A) Dual immunofluorescence analysis was per- formed on kidney cryosections from 7-week-old wild-type and Alport mice using antibodies for podocin (a slit diaphragm protein) and DDR1 (a collagen receptor). Clear co-localization is apparent, placing DDR1 at the foot processes (bar = 15 μm). (B) Super-resolution structured illumination microscopy (SR-SIM) of dual immunofluorescence staining of a capillary loop from a 7-week-old Alport mouse stained with anti-DDR1 antibodies (in red) and anti-collagen α1(III) antibodies (in green). The adjacent localization (arrowheads) indicates basement membrane localization of collagen α1(III) (bar = 5 μm). (C) RNA-seq results from wild-type and Alport glomeruli show a marked (>20-fold) increase in the expression of Col3a1 mRNA relative to wild-type. These results were confirmed using real-time RT-PCR (data not shown) and microarray analysis [8]. (D) ImageJ analysis of the relative fluorescence for immunostains of wild-type and Alport glomeruli (six independent glomeruli each) shows significant increases of fluorescence intensity in Alport mice. (E) Western blotting shows clear increases in the 139 kDa band corresponding to collagen α1(III). (F) Quantification of the relative band intensity for triplicate blots of wild-type and Alport mouse glo- meruli indicates significantly elevated abundance of collagen α1(III) in Alport glomeruli relative to wild-type, consistent with the RNA-seq findings. *p < 0.05, ***p < 0.001.

Figure Lengend Snippet: Figure 4. Collagen α1(III) activates DDR1 receptors both in vitro and in vivo. (A) Cells were treated or not with collagen III and after 12 h, stained with antibodies against either total DDR1 or phospho-DDR1 (pDDR1) (bar = 5 μm). (B) Cryosections from 7-week-old wild-type and Alport mice were dual immunostained with antibodies specific for pDDR1 or WT1 (a podocyte nuclear marker) (bar = 15 μm). Results indicate that collagen III activates DDR1 receptors both in vitro and in vivo in glomerular podocytes. Arrowheads denote areas of WT1 and pDDR1 co-localization.

Figure Lengend Snippet: Figure 5. The collagen IV α1/α2 network in Alport GBM does not activate DDR1. Cryosections from 5-week-old integrin α1-null Alport mice were stained with antibodies for the indicated proteins. Note the absence of collagen α1(III) in the GBM and the absence of pDDR1 nuclear immunostaining in the podocytes. This indicates that the collagen IV α1/α2 network does not activate DDR1. Bar = 15 μm.
