Matrix Biol Plus 2022; 13:100101. [PMID: 35198964 PMCID: PMC8841889 DOI: 10.1016/j.mbplus.2022.100101] [Citation(s) in RCA: 16] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2021] [Revised: 01/08/2022] [Accepted: 01/20/2022] [Indexed: 11/26/2022] Open
Abstract
Collagen cleavage in tumors is primarily mediated by FAP+ cancer-associated fibroblasts. Collagen fibers are cleaved in an MMP-dependent manner. Released collagen fragments are internalized by M2-like tumor-associated macrophages and cancer-associated fibroblasts. The mannose receptor is central in collagen internalization by tumor-associated macrophages.
Increased remodeling of the extracellular matrix in malignant tumors has been shown to correlate with tumor aggressiveness and a poor prognosis. This remodeling involves degradation of the original extracellular matrix (ECM) and deposition of a new tumor-supporting ECM. The main constituent of the ECM is collagen and collagen turnover mainly occurs in a sequential manner, where initial proteolytic cleavage of the insoluble fibers is followed by cellular internalization of large well-defined collagen fragments for lysosomal degradation. However, despite extensive research in the field, a lack of consensus on which cell types within the tumor microenvironment express the involved proteases still exists. Furthermore, the relative contribution of different cell types to collagen internalization is not well-established. Here, we developed quantitative ex vivo collagen degradation assays and show that the proteases responsible for the initial collagen cleavage in two murine syngeneic tumor models are matrix metalloproteinases produced by cancer-associated fibroblasts and that collagen degradation fragments are endocytosed primarily by tumor-associated macrophages and cancer-associated fibroblasts from the tumor stroma. Using tumors from mannose receptor-deficient mice, we show that this receptor is essential for collagen-internalization by tumor-associated macrophages. Together, these findings identify the cell types responsible for the entire collagen degradation pathway, from initial cleavage to endocytosis of fragments for intracellular degradation.

Abstract
Progression through dissemination to tumor-surrounding tissues and metastasis development is a hallmark of cancer that requires continuous cell-to-cell interactions and tissue remodeling. In fact, metastization can be regarded as a tissue disease orchestrated by cancer cells, leading to neoplastic colonization of new organs. Collagen is a major component of the extracellular matrix (ECM), and increasing evidence suggests that it has an important role in cancer progression and metastasis. Desmoplasia and collagen biomarkers have been associated with relapse and death in cancer patients. Despite the increasing interest in ECM and in the desmoplastic process in tumor microenvironment as prognostic factors and therapeutic targets in cancer, further research is required for a better understanding of these aspects of cancer biology. In this review, published evidence correlating collagen with cancer prognosis is retrieved and analyzed, and the role of collagen and its fragments in cancer pathophysiology is discussed.

Extracellular matrix remodeling effects of serum amyloid A1 in the human amnion: Implications for fetal membrane rupture. Am J Reprod Immunol 2018; 81:e13073. [PMID: 30461130 DOI: 10.1111/aji.13073] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/20/2018] [Revised: 10/30/2018] [Accepted: 11/15/2018] [Indexed: 12/14/2022] Open
Abstract
PROBLEM Rupture of fetal membranes is a crucial event at parturition, which is preceded by extensive extracellular matrix (ECM) remodeling. Our recent studies have demonstrated that the human fetal membranes are capable of de novo synthesis of serum amyloid A1 (SAA1), an acute phase protein, and the abundance of SAA1 in the amnion was increased at parturition. However, the exact role of SAA1 in human parturition remains to be established. METHOD OF STUDY The effects of SAA1 on the abundance of collagenases and lysyl oxidase, the enzyme that cross-links collagens, were investigated in culture primary human amnion fibroblasts and tissue explants with an aim to examine the involvement of SAA1 in the ECM remodeling in the amnion. RESULTS Serum amyloid A1 (SAA1) time- and dose-dependently increased the abundance of collagenases MMP-1, MMP-8, and MMP-13, while decreased the abundance of lysyl oxidase-like 1 (LOXL1). These effects of SAA1 were attenuated by siRNA-mediated knockdown of the Toll-like receptor (TLR) 4 and its antagonist CLI-095, but not by siRNA-mediated knockdown of TLR2. Furthermore, the inhibitors for NF-κB (JSH-23) and mitogen-activated protein kinases (MAPKs) p38 (SB203580) and JNK (SP600125) could also attenuate the effects of SAA1, while the inhibitor for MAPK ERK1/2 (PD 98059) could block the effects of SAA1 only on MMP-1, MMP-8, and LOXL1 but not on MMP-13. CONCLUSION These data highlight a possible role for SAA1 in ECM remodeling preceding membrane rupture by regulating the expression of collagenases MMP-1, MMP-8, MMP-13, and LOXL1 through TLR4-mediated activation of the NF-κB and MAPK pathways in amnion fibroblasts.
