Skin aging is one of the degenerative processes influenced by tyrosinase, elastase, collagenase, hyaluronidase, and matrix metalloproteinase-9 (MMP9) activity. One promising avenue for discovering antiaging therapeutics is the peptides from the spine. The aim of this study was to explore the potential of peptides from spine as a multitarget inhibitor for recombinant antiaging therapies through in silico approaches.

Matrix metalloproteinase-8 (MMP-8), a type II collagenase, is a key enzyme in the degradation of collagens and is implicated in various pathological processes, making it a promising target for drug discovery. Despite advancements in the development of MMP-8 inhibitors, concerns over potential adverse effects persist. This study aims to address these concerns by focusing on the development of novel compounds with improved safety profiles while maintaining efficacy.

Matrix metalloproteinase-2 (MMP-2), a zinc-dependent enzyme, plays a critical role in the degradation and remodeling of the extracellular matrix (ECM). As a member of the gelatinase subgroup of matrix metalloproteinases, MMP-2 is involved in a variety of physiological processes, including tissue repair, wound healing, angiogenesis, and embryogenesis. It is primarily responsible for the degradation of type IV and V collagen, fibronectin, laminin, and elastin, which are essential components of the ECM.

The phosphatidylinositol 3-kinase (PI3K)/AKT/mammalian target of rapamycin (mTOR) pathway is frequently hyperactivated in triple-negative breast cancers (TNBCs) associated with poor prognosis and is a therapeutic target in breast cancer management. Here, we describe the effects of repression of mTOR-containing complex 1 (mTORC1) through knockdown of several key mTORC1 components or with mTOR inhibitors used in cancer therapy. mTORC1 repression results in an ∼10-fold increase in extracellular matrix proteolytic degradation.

Purpose: The stromal cell protein metalloproteinase 9 (MMP9), associated with extracellular matrix degradation and remodeling, promotes tumor invasion and metastasis and regulates cell adhesion molecule and cytokine activity. This study evaluated MMP9 in pan-cancer and screened for compounds and drug candidates that can inhibit it.
Methods: MMP9 expression in pan-cancer tissues was evaluated in a pan-cancer dataset from the University of California Santa Cruz database, along with the correlation between MMP9 and the tumor microenvironment (TME), RNA modification genes, and tumor mutation burden.
