(H) Representative sections of tubular cyst origin in the parental Pkd1 −/− , Pkd1 −/− with one-copy SB Pkd1 , or high-copy SB Pkd1 transfer. Tubular segments were stained using immunofluorescent markers for proximal (green), distal (blue), and collecting (red) as depicted on the pictogram. Distribution of specific tubular segment diameter was analyzed at selected time points in the histogram (below) with colors matching to the tubular markers. The black histogram accounts for unstained, multistained, and glomerular cysts. Relative frequency of cysts from a specific tubular origin was quantified per total number of tubules of that same segment (below). Cystic diameter threshold was defined at ≥22 μm and the shaded area represents normal tubular size. (I) Global quantitative analysis of cystic tubular segments relative to all tubular segments in Pkd1 −/− with one- or high-copy SB Pkd1 transfers. Renal cysts with one-copy SB Pkd1 are abrogated in proximal tubules, delayed in distal tubules, and incompletely rescued in collecting ducts during maturation. High-copy SB Pkd1 transfer in kidneys of Pkd1 −/− mice protected all tubular segments from developing cysts during maturation and, at post-maturation, was sufficient to suppress proximal and collecting tubular cyst development but insufficient for distal tubules. ♦♦♦♦ p < 0.0001, ♦♦ p < 0.01, ♦ p < 0.05.

Figure Lengend Snippet: Endogenous Pkd1 tubular cell expression pattern in wild-type mouse kidney (A) Pkd1 cellular expression in wild-type kidney at P5 in individual tubular segments was carried out by in situ Pkd1 expression pattern detection (white dots; RNAscope) with co-detection by immunofluorescence of specific tubular markers. Wild-type proximal tubules correspond to very weak dot signals, distal and collecting tubules display substantially more abundant Pkd1 dot signals. (B) Wild-type kidney section at P20 with co-detection of Pkd1 by RNAscope and tubular segment markers. The top illustrates specifically Pkd1 signals from RNAscope ISH, tubular markers, and co-detection in kidneys. Proximal, distal, and collecting tubules with magnified region marked by asterisks with co-detection of Pkd1 dot signals are illustrated below. (C) Pkd1 expression in wild-type glomeruli at P5 and P20 by RNAscope. Distinct but weak Pkd1 signals are detected over mesangial cells at P5, which are of higher intensity at P20 and visible in visceral cells. Pkd1 expression in Pkd1 −/− glomeruli with Pkd1 wt2 transfer at P5 has a similar pattern with considerably more intense dot signals than wild-type glomeruli. Scale as indicated.

Figure Lengend Snippet: Spatial and cellular Pkd1 expression from transgene transfer in Pkd1 −/− kidneys alone or merged with individual or all tubular markers (A) Kidneys of Pkd1 −/− with one-copy SB Pkd1 transfer at P5 by RNAscope exhibit generally weak Pkd1 signals in non-cystic and cystic tubules, with occasional intense dot signals distinctive from wild-type kidneys. Scale: 50 μm. (B) Kidneys of Pkd1 −/− with high-copy SB Pkd1 transfer at P20 have strong Pkd1 dot signals in comparison with one-copy SB Pkd1 . Pkd1 signals with high-copy SB Pkd1 transfer are more intense in the majority of distal and collecting tubules than in proximal tubules. Signals are detected in non-cystic and small/intermediate cystic tubules and of mostly lower Pkd1 intensity in large cystic tubules. Scale: 50 μm. (C) Kidneys of Pkd1 −/− with Pkd1 Mini transfer at P5 display more diffuse and widespread Pkd1 signals with numerous dots of low intensity, whether of cystic or non-cystic tubules and regardless of the tubular segments. Large cysts in collecting tubules generally exhibit similar uniform low Pkd1 expression. Scale: 50 μm.

Figure Lengend Snippet: Comparison of Pkd1 −/− gene-targeted transfer potential on PKD time-course progression or correction (A) Timeline of renal cyst initiation in Pkd1 −/− mice at e15.5 and death by birth within 5 days. Pkd1 −/− mice with Pkd1 Mini transfer display cysts at birth until P15, whereas those with one-copy SB Pkd1 transfer develop cysts later at P3 until P15. Pkd1 −/− mice with high-copy SB Pkd1 transfer initiate cysts between P10 and P15 and progress to severe cysts by ∼4 months. Pkd1 −/− mice with Pkd1 wt transfer have a completely rescued phenotype. (B) Schematic representation of cyst appearance and progression in different tubular segments, and severity over time for the three different transgene transfers. (C) Survival expectancy of Pkd1 −/− mice, estimated as 5 days, is markedly extended from e15.5 to P15 or equivalent to a 20 day period for both transfers, Pkd1 Mini or one-copy SB Pkd1 in Pkd1 −/− mice, an appraisal of significantly high impact. In Pkd1 −/− mice with high-copy SB Pkd1 transfer, the very slow kinetics of disease progression extended life expectancy by an impressive ∼25-fold. Pkd1 −/− mice with Pkd1 wt transfer are predicted to have a normal lifespan.

Article Title: Loss of Polycystin-1 causes cAMP-dependent switch from tubule to cyst formation

doi: 10.1016/j.isci.2022.104359

Figure Lengend Snippet: Deletion of PC1 results in a switch from tubulogenesis to cyst formation and is accompanied by an increase of cAMP and a decrease in cell motility (A and B) PC1-competent clonal cells (PKD1 +/+ ) mainly formed tubule-like structures within a collagen matrix when incubated with control medium (Ctrl). In contrast, PC1-deficient cells (PKD1 −/− ; shown for two different clones #1 and #2) primarily formed cysts within the collagen matrix in the presence of control medium (Ctrl). Application of forskolin (FSK; 10μM) to PKD1 +/+ cells turned them into cyst-forming cells resembling the phenotype obtained by PC1-deletion under control condition. Incubation of PKD1 −/− cells with forskolin (FSK; 10μM) had no impact on their morphology. (A) provides the analysis of the ratio of cystic to tubule-like formed structures (analysis of 128 images from n = 4 individual experiments). (B) shows representative images after five days of culture within a collagen I matrix. (C) Measurements of cAMP concentrations revealed similar values in clonal PC1-competent cells (PKD1 +/+ ) compared to wild type cells (wt). PC1-deletion resulted in significantly elevated cAMP levels in PC1-deficient cells (PKD1 −/− #1 and #2) with PKD1 +/+ set as 100% (n = 6 individual experiments). Incubation of the cells with forskolin (FSK; 10μM) resulted in a significant increase of cAMP in PC1-competent and PC1-deficient cells to a similar level (n = 3 individual experiments). (D and E) Movement of spheroids of PC1-competent and PC1-deficent cells (shown for PKD1 −/− #1) within the collagen matrix was captured by live imaging of 30 spheroids per condition and cell type from n = 3 individual experiments for 48 h. Deletion of PC1 resulted in decreased motility. Incubation with forskolin (FSK; 10μM) also led to a reduction of motility in PC1-competent cells to a similar degree obtained from PC1-defcient cell under control condition. Application of forskolin to PC1-deficient spheroids had no additional effect. (D) Analysis of movements of spheroids within the matrix. (E) Representative traces of single spheroids within 48 h of imaging. ∗significant compared to PKD1 +/+ -Ctrl; § significant compared to PKD1 −/− #1-FSK and PKD1 −/− #2-FSK, respectively.

Thereafter PC1-competent cysts (n = 47 from three individual experiments) and PC1-deficient cysts (n = 75 from four individual experiments) were punctured with a pulled glass capillary microneedle and the use of a micromanipulator. Punctured cysts were imaged for 70 h as depicted in (A). (B) Analysis of the ratio of cysts forming tubules after injury. (C) Analysis of the length of the formed tubules within 70 h.

Figure Lengend Snippet: Loss of PC1 and increase of cAMP lead to dense cell aggregation and reduction of disseminating single cells PC1-competent cells (PKD1 +/+ ) and PC1-deleted cells (PKD1 −/− ) were cultured at low density (3200 cells/cm 2 ) and analyzed with regard to their growing pattern. (A) PC1-competent cells kept growing in a disseminated pattern forming small colonies with a significant amount of single cluster-independent cells. PC1-deleted cells resulted in dense and evenly bordered cell aggregations with only a few single cells being detectable outside these cell formations. Forskolin (FSK; 10μM) significantly reduced the number of single PC1-competent and PC1-deficient cells (analysis of 72 images from n = 3 individual experiments). (B) Voronoi-based analysis of cell distance between clustering cells (defined as > two cells). Cell distance was significantly higher in PC1-competent cells compared to PC1-deficient cells and PC1-competent cells in the presence of forskolin. (C) Analysis of cell density within bigger cell aggregates (comprising 10 - 50 cells/cluster). Cells were significantly less dense within the clusters of PC1-competent cells under control condition compared to PC1-deficient cells or PC1-competent cells in the presence of forskolin.
