Whole kidneys at embryonic day 16.5: wildtype (WT) vs. conditional Dot1-knockout (KO) from Six2-positive nephron progenitor cells (NPC)

Project description:Transcriptional profiling of whole kidneys from Six2CreEGFP mice without (WT) or with (KO) homozygously floxed DOT1 alleles at the age of embryonic day 16.5. This experiment aimed to uncover the genome-wide alternation in gene expression resulting from the removal of DOT1 gene in the nephron progenitor population (Six2 positive) and successive changes to the series of events in kidney development.

Mmp14 is essential for circadian clock rhythmicity in fibroblasts

Project description:Membrane type I-matrix metalloproteinase (MT1-MMP/Mmp14) is an unusual MMP because it is essential for survival in mice with multiple organ systems being affected for reasons that are unclear. Here, we show that the protein (MT1-MMP) and gene (Mmp14) are under strict circadian clock control and conditional knockout in fibroblasts leads to ~16% of the proteome losing or inverting circadian rhythmicity. The result is loss of the actin cytoskeleton and cell-matrix adhesions and major imbalance of the matrisome. Lack of collagen-I monomer turnover results in excess fibril formation in the absence of Mmp14. In the absence of Mmp14, paired-like homeodomain transcription factor 2 (Pitx2) is upregulated and remains in the nucleus where it drives Plod2 expression. The overall result is accumulation of collagen fibrils and elevated pyridinoline crosslinking that renders collagen fibrils insoluble. In conclusion, Mmp14 is a master regulator of circadian rhythms affecting the actin cytoskeleton and cell microenvironment.

Expression array of stromal Mmp14-targeted mammary glands

Project description:Mammary gland branching morphogenesis is thought to depend on the mobilization of proteolytic machinery from the matrix metalloproteinase (MMP) family, namely MT1-MMP/MMP14, to drive coordinated epithelial cell invasion through the interstitial extracellular matrix, but the dominant effector has remained undefined. Unexpectedly, we find MMP14 controls postnatal mammary gland branching from the periductal stroma. Transcriptome profiling of stromal cell-targeted mammary glands was used to characterize the impact of stromal Mmp14-targeting on the growth factor and signaling cascades implicated in mammary gland morphogenesis. Transcriptome profiling of ductal networks and associated stroma was used to investigate the functional roles of MMP14 in the postnatal mammary gland stroma in an unbiased fashion.

Expression data from embryonic day 16.5 or postnatal day 3 mouse liver

Project description:mRNA degradation critically contributes to liver development and function. The CCR4-NOT complex serves as a major deadenylase that initiates mRNA degradation. We used microarrays to identify deregulated genes in the livers lacking Cnot3, a core subunit of the CCR4-NOT complex.

Mmp14-Dependent Remodeling of the Pericellular-Dermal Collagen Interface Governs Fibroblast Survival

Project description:Dermal fibroblasts deposit type I collagen, the dominant extracellular matrix molecule found in skin, during early postnatal development. Coincident with this biosynthetic program, fibroblasts proteolytically remodel pericellular collagen fibrils by mobilizing the membrane-anchored matrix metalloproteinase, Mmp14. Unexpectedly, dermal fibroblasts in Mmp14-/- mice commit to a large-scale apoptotic program that leaves skin tissues replete with dying cells. A requirement for Mmp14 in dermal fibroblast survival is recapitulated in vitro when cells are embedded within, but not cultured atop, 3-dimensional hydrogels of cross-linked type I collagen. In the absence of Mmp14-dependent pericellular proteolysis, dermal fibroblasts fail to trigger β1 integrin activation and instead actuate a TGF-β1/phospho-JNK stress response that leads to apoptotic cell death in vitro as well as in vivo. Taken together, these studies identify Mmp14 as a requisite cell survival factor that maintains dermal fibroblast viability in postnatal dermal tissues.

MMP14 cleaves PTH1R in the chondrocyte derived osteoblast lineage, curbing signaling intensity for proper bone anabolism

Project description:Bone homeostasis is regulated by hormones such as parathyroid hormone (PTH). While PTH can stimulate osteo-progenitor expansion and bone synthesis, how the PTH-signaling intensity in progenitors is controlled is unclear. Endochondral bone osteoblasts arise from perichondrium-derived osteoprogenitors and hypertrophic chondrocytes (HC). We found, via single-cell transcriptomics, HC descendent cells activate membrane-type 1 metalloproteinase 14 (MMP14) and the PTH pathway as they transition to osteoblasts in neonatal and adult mice. Unlike Mmp14 global knockouts, postnatal day 10 (p10) HC lineage-specific Mmp14 null mutants (Mmp14ΔHC) produce more bone. Mechanistically, MMP14 cleaves the extracellular domain of PTH1R, dampening PTH signaling, and consistent with the implied regulatory role, in Mmp14ΔHC mutants, PTH signaling is enhanced. We found HC-derived osteoblasts contribute ~50% of osteogenesis promoted by treatment with PTH 1-34 and this response was amplified in Mmp14ΔHC. MMP14 control of PTH signaling likely applies also to both HC- and non-HC-derived osteoblasts because their transcriptomes are highly similar. Our study identifies a novel paradigm of MMP14 activity-mediated modulation of PTH signaling in the osteoblast lineage, contributing new insights into bone metabolism with therapeutic significance for bone-wasting diseases.
