Human apical-out nasal organoids reveal an essential role of matrix metalloproteinases in airway epithelial differentiation

Project description:Extracellular matrix (ECM) assembly/disassembly is a critical regulator for airway epithelial development and remodeling. Airway organoid is widely used in respiratory research, yet there is limited study to indicate the roles and mechanismsof ECM organization in epithelial growth and differentiation by using in vitro organoid system. Moreover, most of current Matrigel-based airway organoids are in basal-out orientation where accessing the apical surface is challenging. We present a novel human apical-out airway organoid using a biochemically defined hybrid hydrogel system. During human nasal epithelial progenitor cells (hNEPCs) differentiation, thegel gradually degraded, leading to the organoid apical surfaces facing outward. The expression and activity of ECM-degrading enzymes, matrix metalloproteinases (MMP7, MMP9, MMP10 and MMP13) increased during organoid differentiation,where inhibition of MMPs significantly suppressed the normal ciliation, resulting in increased goblet cell proportion. Moreover, a decrease of MMPs was found in goblet cell hyperplastic epithelium in inflammatory mucosa. This system reveals essential roles of epithelial-derived MMPs on epithelial cell fate determination, and provides an applicable platform enabling further study for ECM in regulating airway development in health and diseases.

Matrix Metalloproteinases After Surgery and/or Radiofrequency Ablation in Patients With Liver Metastases From Colorectal Cancer

Project description:RATIONALE: Studying samples of blood from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict how patients will respond to treatment. PURPOSE: This research trial is studying matrix metalloproteinases after surgery or radiofrequency ablation in patients with liver metastases from colorectal cancer.

The gelatinases, matrix metalloproteinases 2 and 9, play individual roles in skeleton development

Project description:The gelatinases, a subgroup of the matrix metalloproteinases (MMPs) superfamily are composed of two members; MMP2 and MMP9. They are known to degrade gelatin among other components of the extracellular matrix. Recently, the two gelatinases were found to be necessary for neural crest cell migration and to compensate for each other loss in these cells. To characterize their involvement in the skeletal system, and to better reveal their individual or common roles, we have generated double knockout (dKO) mice, lacking both MMP2 and MMP9. The transcriptome of calvaria, growth plate and femoral cortical bone of P21 C57BL/6J WT, MMP2-/-, MMP9-/- and dKO mice was analyzed by bulk RNA-Seq.

Stably-Inverted Apical-Out Human Upper Airway Organoids for SARS-CoV-2 Infection and Therapeutic Testing

Project description:Apical-out organoids produced through eversion triggered by extra-organoid extracellular matrix (ECM) removal or degradation are generally small, structurally variable, and limited for viral infection and therapeutics testing. This work describes ECM-encapsulating, stably-inverted apical-out human upper airway organoids (AORBs) that are large (~500 µm diameter), consistently spherical, recapitulate in vivo-like cellular heterogeneity, and maintain their inverted morphology for over 60 days. Treatment of AORBs with IL-13 skews differentiation towards goblet cells and the apical-out geometry allows extra-organoid mucus collection. AORB maturation for 14 days induces strong co-expression of ACE2 and TMPRSS2 to allow high-yield infection with five SARS-CoV-2 variants. Dose-response analysis of three well-studied SARS-CoV-2 antiviral compounds [remdesivir, bemnifosbuvir (AT-511), and nirmatrelvir] shows AORB antiviral assays to be comparable to gold-standard air-liquid interface cultures, but with higher throughput (~10-fold) and fewer cells (~100-fold). While this work focuses on SARS-CoV-2 applications, the consistent AORB shape and size, and one-organoid-per-well modularity broadly impacts in vitro human cell model standardization efforts in line with economic imperatives and recently updated FDA regulation on therapeutic testing.

Regulation of matrix metalloproteinases (MMPs) expression and secretion by LIM and SH3 protein (LASP1)

Project description:The process of tumor invasion requires degradation of extracellular matrix by proteolytic enzymes. Cancer cells form protrusive invadopodia, which produce and release matrix metalloproteinases (MMPs) to degrade the basement membrane and thereby allowing metastasis. We investigated the effect of LASP1, a newly identified protein in invadopodia, on expression, secretion and activation of MMPs in invasive breast tumor cells. By analyzing and verifying microarray data sets and performing reporter assays, we demonstrate that LASP1 positively modulates the expression of c-Fos and AP-1 activity, and thereby up-regulates expression of MMP1, -3 and -9 in breast cancer cells. Furthermore, zymography assays and Western blot analysis revealed cytosolic LASP1 promotion of MMP vesicle secretion into the extracellular matrix, thus altering the microenvironment during cancer progression. The newly identified role of LASP1 in regulating matrix degradation by affecting MMP transcription and secretion elucidated the migratory potential observed in studies that investigated the upregulation of LASP1 in aggressive cancers.

Hormone responsiveness and spatial heterogeneityof apical-out endometrial organoids

Project description:We have developed apical-out (AO)- endometrial organoids (EMO) that emulate the in vivo archtecture of endometrial epithelium. The AO-EMO exposes the apical surface of the epithelium. To explore the hormone responsiveness and spatial heterogeneity of AO-EMO, we conducted transcriptomic analysis.
