Effects of Topical Intranasal Doxycycline Treatment in the Rat Allergic Rhinitis Model [PDF]

open access: yesClinical and Experimental Otorhinolaryngology, 2014
ObjectivesAllergic rhinitis (AR) is a chronic upper respiratory tract disease that inflames the mucous membranes of the nose and occurs when circulating inflammatory cells including eosinophils and basophils migrate to and accumulate in the inflammation ...

Salivary profile of matrix metalloproteinase-8, tissue inhibitors of matrix metalloproteinase-1, myeloperoxidase, and nitrous oxide in smokers versus nonsmokers with chronic periodontitis

open access: yesJournal of International Clinical Dental Research Organization, 2021
Background: Smoking is the second strongest modifiable risk factor for periodontal disease. Tissue destruction might result from matrix metalloproteinase (MMP)/tissue inhibitors of MMP (TIMP) imbalance in the diseased tissues.

LPS Counter Regulates RNA Expression of Extracellular Proteases and Their Inhibitors in Murine Macrophages

open access: yesMediators of Inflammation, 2012
Besides their evident importance in host defense, macrophages have been shown to play a detrimental role in different pathological conditions, including chronic inflammation, atherosclerosis, and cancer.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Upregulation of MMP-13 and TIMP-1 expression in response to mechanical strain in MC3T3-E1 osteoblastic cells

open access: yesBMC Research Notes, 2010
Background Mechanical strain plays a significant role in the regulation of bone matrix turnover, which is mediated in part by matrix metalloproteinase (MMP)-13 and tissue inhibitors of matrix metalloproteinase (TIMP)-1. However, little is known about the

COMP–PMEPA1 axis promotes epithelial‐to‐mesenchymal transition in breast cancer cells

open access: yesMolecular Oncology, EarlyView.
This study reveals that cartilage oligomeric matrix protein (COMP) promotes epithelial‐to‐mesenchymal transition (EMT) in breast cancer. We identify PMEPA1 (protein TMEPAI) as a novel COMP‐binding partner that mediates EMT via binding to the TSP domains of COMP, establishing the COMP–PMEPA1 axis as a key EMT driver in breast cancer.

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

open access: yesMolecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

Complex studies on gene polymorphisms of MMP2, MMP3, MMP9 matrix metalloproteinases and TIMP1, TIMP2 tissue inhibitors of metalloproteinases in the patients with primary open-angle glaucoma

open access: yesМедицинская иммунология, 2023
Abnormal expression of matrix metalloproteinases (MMP) in watery moisture in patients with glaucoma may affect regulation of intraocular pressure (IOP). MMP activity is regulated by tissue metalloproteinase inhibitors (TIMP). The imbalance between tissue

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

open access: yesMolecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Proteolysis/antiproteolysis system in apparently healthy men and women of different ages

open access: yesRUDN Journal of Medicine
Relevance. Aging is anatural biological process of aretrograde nature, during which there is an imbalance of all systems, including the matrix metalloproteinase (MMP) system and tissue inhibitors of matrix metalloproteinases (TIMP). And vascular aging is
