Project description:The balance between tissue integrity and efficient immune response is critical for host survival. Here we investigate the role of extra cellular matrix (ECM)-remodeling events in the lung during influenza infection. Using an unbiased genomic and proteomic approach we follow the dynamics of gene and ECM responses in an influenza-infected mouse model, integrated with whole tissue as well as ECM imaging and functional assays. Our study identifies membrane type 1 matrix metalloproteinase (MT1-MMP) as a major host-regulated ECM remodeling collagenase in influenza infection. We show that inhibition of MT1-MMP-driven proteolytic activity protected tissue structural and compositional features. We demonstrate that available influenza treatment (Oseltamivir) is ineffective in preventing the lung ECM damage and is therefore less effective than anti-MT1-MMP treatment in influenza and Streptococcus pneumoniae co-infections. Importantly, the combination between the two treatments resulted in 100% survival. This study highlights the importance of ECM protection for survival during infectious diseases, and paves the way for combined host-pathogen theraphy to fight emerging pathogens.

Project description:ADAMTS9 and ADAMTS20 are homologous secreted proteases implicated in ECM proteolysis and ciliogenesis, but few relevant substrates of these proteases are currently known. Quantitative N-terminomics comparison of RPE-1 cells lacking ADAMTS9 with parental RPE-1 cells identified transmembrane protease MT1-MMP (MMP14) as a novel ADAMTS9 substrate. The resulting enhanced cell-surface MT1-MMP activity in the gene-edited cells contributes to their adhesion defect, but not lack of cilia. A key physiological function of ADAMTS9/20 may be to dampen cell-surface MT1-MMP activity.

Project description:Invasive cancers employ pericellular proteolysis to breach the extracellular matrix and basement membrane barriers and invade the surrounding tissue. Pro-invasive, pro-tumorigenic MT1-MMP is the primary mediator of proteolytic events on the cancer cell surface. Cellular MT1-MMP is synthesized as a latent zymogen. The latency of MT1-MMP is maintained by its N-terminal inhibitory prodomain. Our study reveals a critical mechanism underlying the activation pathway and subsequent execution of the tumor-promoting function of MT1-MMP. Evidence suggests that the prodomain undergoes intradomain cleavage at the PGD↓L50 cleavage site followed by the release of the degraded prodomain by furin cleavage of the R108RKR111↓Y112 site. These events, only if combined, cause the activation of MT1-MMP. The significance of these molecular events to the pro-tumorigenic function of MT1-MMP in malignancy remained, however, unidentified. To identify the functional importance of the PGD↓L50 intradomain cleavage in the activation and tumorigenic program of MT1-MMP, our current studies employed the cells which expressed the wild-type prodomain-based fluorescent biosensor and the mutant biosensor with the inactivated PGD↓L50 cleavage site (L50D mutant) and also the cells with the enforced expression the wild-type and mutant MT1-MMP. Using cell-based tests and orthotopic breast cancer xenografts in mice, we demonstrated that the intradomain cleavage of the PGD↓L50 sequence of the prodomain is essential for the pro-tumorigenic function of MT1-MMP. Our study contributes to the growing consensus for the design of selective, precisely focused MT1-MMP inhibitors in cancer.

A theoretical model of type I collagen proteolysis by matrix metalloproteinase
(MMP) 2 and membrane type 1 MMP in the presence of tissue inhibitor of
metalloproteinase 2.

Abstract:
One well documented family of enzymes responsible for the proteolytic processes
that occur in the extracellular matrix is the soluble and membrane-associated
matrix metalloproteinases. Here we present the first theoretical model of the
biochemical network describing the proteolysis of collagen I by matrix
metalloproteinases 2 (MMP2) and membrane type 1 matrix metalloproteinases
(MT1-MMP) in the presence of the tissue inhibitor of metalloproteinases 2
(TIMP2) in a bulk, cell-free, well stirred environment. The model can serve as a
tool for describing quantitatively the activation of the MMP2 proenzyme
(pro-MMP2), the ectodomain shedding of MT1-MMP, and the collagenolysis arising
from both of the enzymes. We show that pro-MMP2 activation, a process that
involves a trimer formation of the proenzyme with TIMP2 and MT1-MMP, is
suppressed at high inhibitor levels and paradoxically attains maximum only at
intermediate TIMP2 concentrations. We also calculate the conditions for which
pro-MMP2 activation is maximal. Furthermore we demonstrate that the ectodomain
shedding of MT1-MMP can serve as a mechanism controlling the MT1-MMP
availability and therefore the pro-MMP2 activation. Finally the proteolytic
synergism of MMP2 and MT1-MMP is introduced and described quantitatively. The
model provides us a tool to determine the conditions under which the synergism
is optimized. Our approach is the first step toward a more complete description
of the proteolytic processes that occur in the extracellular matrix and include
a wider spectrum of enzymes and substrates as well as naturally occurring or
artificial inhibitors.

Project description:Integrin signaling plays a fundamental role in the establishment of focal adhesions and the subsequent formation of invadopodia in malignant cancer cells. Invadopodia facilitate localized adhesion and degradation of the extracellular matrix (ECM), which promote tumour cell invasion and metastasis. Degradation of ECM components is often driven by membrane type-1 matrix metalloproteinase (MT1-MMP), and we have recently shown that regulation of enzyme internalization is dependent on signaling downstream of β1 integrin. Phosphorylation of the cytoplasmic tail of MT1-MMP is required for its internalization and delivery to Rab5-marked early endosomes, where it is then able to be recycled to new sites of invadopodia formation and promote invasion. Here we found that inhibition of β1 integrin, using the antibody AIIB2, inhibited the internalization and recycling of MT1-MMP that is necessary to support long-term cellular invasion. MT1-MMP and β1 integrin were sequestered at the cell surface when β1-integrin was inhibited, and their association under these conditions was detected using immunoprecipitation and mass spectrometry analysis. Sequestration of β1 integrin and MT1-MMP at the cell surface resulted in the formation of large invadopodia and local ECM degradation; however, the impaired internalization and recycling of MT1-MMP and β1 integrin ultimately led to a loss of invasive behaviour.

Project description:While a common symptom of influenza and coronavirus disease 2019 (COVID-19) is fever, its physiological role on host resistance to viral infection remains less clear. Here, we demonstrate that exposure of mice to the high ambient temperature of 36 °C increase host resistance to viral pathogens including influenza virus and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). High heat-exposed mice increase basal body temperature over 38 °C to enable more bile acids production in a gut microbiota-dependent manner. The gut microbiota-derived deoxycholic acid (DCA) and its plasma membrane-bound receptor Takeda G-protein-coupled receptor 5 (TGR5) signaling increase host resistance to influenza virus infection by suppressing virus replication and neutrophil-dependent tissue damage. Furthermore, the DCA and its nuclear farnesoid X receptor (FXR) agonist protect Syrian hamster from lethal SARS-CoV-2 infection. Moreover, we demonstrate that certain bile acids are reduced in the plasma of COVID-19 patients who developed moderate I/II disease compared with minor illness group. These findings uncover an unexpected mechanism by which virus-induced high fever increases host resistance to influenza virus and SARS-CoV-2 in a gut microbiota-dependent manner.

Project description:Full-length membrane PTK7 and its N-terminal and C-terminal proteolytic fragments induced differential transcriptional profiles in HT1080 cells. Pseudokinase PTK7 is an essential regulator of planar cell polarity (PCP) and directional cell motility in the course of vertebrate development and embryogenesis, and regulates both the non-canonical Wnt/PCP and canonical Wnt pathways. In contrast to its well-appreciated, crucial role in embryo development, the functional importance of the intact full-length PTK7 in malignancy is still a matter of debate. In humans, the full-length membrane PTK7 consists of seven extracellular immunoglobulin-like (Ig) domains, a transmembrane region, a juxtamembrane region and a catalytically inert cytoplasmic tyrosine kinase (PTK) domain. Because pericellular proteolysis plays a primary role in cell migration, especially in the directional locomotion of tumor cells, it is likely that proteolysis and PCP converge to promote efficient directed cancer cell migration. In agreement, the functionality of PTK7 is directly regulated by proteolysis. Ubiquitous membrane type-1 matrix metalloproteinase (MT1-MMP), arguably the primary enzyme in pericellular proteolysis and cancer cell migration, cleaves the PKP621M-bM-^FM-^SLI sequence in the seventh Ig-like domain of membrane PTK7 and this cleavage results in the liberation of the N-terminal soluble PTK7 fragment (sPTK7). MT1-MMP proteolysis is followed by the cleavage of the C-terminal residual portion of PTK7 by ADAMs, including ADAM17. The ectodomain shedding is a prerequisite for the intramembrane cleavage of PTK7 by M-NM-3-secretase. This cleavage releases the C-terminal cytoplasmic tail fragment of PTK7, which is then either degraded by the proteasome or transported to the nucleus.The limited pre-existing data suggest that the full-length membrane PTK7 and its proteolytic products cause an opposing effect on the efficiency of cell migration. Thus, the continuing presence of the full-length membrane PTK7 on the plasma membrane down-regulated the myosin light chain (MLC) phosphorylation (a downstream event of the Wnt/PCP pathway) and, in agreement, reduced migration efficiency of fibrosarcoma HT1080 cells. MT1-MMP proteolysis of PTK7 reversed the inhibitory effect of the full-length membrane PTK7, resulted in the accumulation of the stable N-terminal sPTK7 fragment in the extracellular milieu and promoted cell invasion of HT1080 cells. Expression of the Chz PTK7 mutant that exhibited an additional PEKM-bM-^FM-^SLK503 MT1-MMP cleavage site in the junction region between the fifth and the sixth Ig-like domains stimulated cell migration even further. These effects suggest the existence of the intriguing and specific downstream mechanisms by which the intact PTK7, its digest fragments and the homo- and heterodimeric complexes between the PTK7 membrane, soluble and intracellular portions control cell function. These mechanisms, however, have not been precisely investigated in the earlier works by us and others. Understanding of these mechanisms will shed additional light on the role that PTK7 alone as well as in its combination with MT1-MMP, ADAMs and M-NM-3-secretase plays in cancer cell migration. To evaluate in detail the effects of PTK7 and its proteolytic fragments on genome-wide transcriptional regulation, we specifically employed fibrosarcoma HT1080 cells. These highly invasive cells express low endogenous levels of PTK7 but high levels of active MT1-MMP and ADAMs. Because of these parameters, we could manipulate this preudokinase functionality using HT1080 cells transfected with the recombinant PTK7 constructs. The cells we employed included the PTK7 knock-out cells (shPTK7 cells), cells with the enforced overexpression of the original membrane PTK7 (PTK7 cells) and its Chuzhoi (Chz) mutant that exhibited an additional PEKM-bM-^FM-^SLK503 MT1-MMP cleavage site (Chz cells), and the cells, which overexpresssed multiple deletion species of PTK7. These species represented the soluble (sPTK7), membrane and cytoplasmic C-terminal digest fragments that resulted because of PTK7 cleavage by MT1-MMP (cPTK7/622-1070) and ADAM/gammaM-bM-^@M-^Ssecretase (cPTK7/726-1070). Expression of these constructs allowed us to specifically determine the downstream effect of PTK7 proteolysis on gene expression. HT1080 cells were stably transfected with the PTK7 constructs. Cells (1 x 10^4/ml) were plated in DMEM- 10% FBS in a 100-mm dish and grown for 72 h to produce a subconfluent culture. Total cellular RNA was extracted using a Direct-zol RNA MiniPrep kit (Zymo Research). Biotin-labeled cRNA samples were prepared using the Illumina RNA Amplification Kit (Ambion). The labeled cRNA (750 ng) was hybridized for 18 h at 58M-BM-0C to the HumanHT-12 v4 Expression BeadChip (Illumina). BeadChips were then developed using fluorolink streptavidin-Cy3 (GE Healthcare). Array chips were scanned using an Illumina BeadArray Reader. The initial data extraction and normalization were performed using the BeadArray Reader and GeneSpring GX software (Agilent).
