The potential involvement of intracellular proteases in the pathophysiology of fibromyoma was studied by assay of activity of two proteolytic enzymes in fibromyoma and adjacent normal myometrium. Protease I, a soluble acid protease and protease II, a particulate protease optimally active at the
We investigated the effect of relaxin on extracellular matrix remodeling in cultured myometrial compared with leiomyoma smooth muscle cells. Relaxin increases elastase activity and protease inhibitor expressions in myometrial smooth muscle cells, but no effect was observed in leiomyoma cells.
Leiomyomas have abundant extracellular matrix (ECM), with upregulation of versican, a large proteoglycan.
We investigated ADAMTS (a disintegrin-like and metalloprotease with thrombospondin type 1 motifs) protease-mediated versican cleavage in myometrium and leiomyoma and the effect of versican
OBJECTIVE
Decidual cells are thought to be involved in the maintenance of pregnancy. We conducted this study to evaluate the cellular function of endometrial stromal cells (ESCs) transitioning to decidualization.
METHODS
Normal endometrial specimens were obtained from premenopausal patients who had
OBJECTIVE
Cathepsin B is a major cysteine protease involved in the degradation of extracellular matrix proteins, as well as in the activation of precursor forms of other proteases and in release of matrix-bound growth factors. We assessed the expression and activity of cathepsin B, and the
Calpain 6 (CAPN6) is one of the calcium-dependent intracellular nonlysosomal proteases that are dysregulated in uterine leiomyomas (UtLMs). However, its function and mechanism in UtLMs is still unknown.The correlation between CAPN6 expression and UtLMs was OBJECTIVE
To determine the profile of differentially expressed genes in leiomyoma and matched unaffected myometrium and to identify the genes whose expression are altered after gonadotropin releasing hormone analogue (GnRHa) therapy.
METHODS
Using total RNA isolated from untreated and GnRHa-treated
OBJECTIVE
Matrix metalloproteinase-2 and -9 (MMP-2 and -9) are proteolytic enzymes degrading extracellular matrix proteins, mainly collagen type IV. Recent reports show that these proteases may be implicated in the growth of uterine leiomyoma. The aim of the present study was to evaluate the
An alteration of the retinoid pathway can influence the development of uterine leiomyomas in animal models, and retinoids have shown efficacy in inhibiting the growth of this benign tumor both in vitro and in vivo. However, the underlying mechanisms and biological implications are unclear. The
We have investigated the capability of the different native ER forms, present in cytosols from human uterine tissues, of reacting with the antiestrogen [3H]Tamoxifen aziridine ([3H]TA) and with the Estrogen Responsive Element (ERE). Cytosols from uterine leiomyoma (myoma) prepared in buffer
In preparation for studies of progestin receptor dynamics in human uterine tissues, we have investigated the effect of tissue handling and the protease inhibitor leupeptin on the molecular forms of progestin receptors in human endometrium, myometrium, and leiomyoma. Tritiated R5020
HE4 protein (human epididymis protein-4), which is the fourth subfraction of human epithelial protein, is a glycoprotein widely used as a tumor marker in ovarian cancer. If was first discovered in the epididymal epithelium and recognized as a protease inhibitor contributing to sperm OBJECTIVE
Are increased sVCAM-1 and sICAM-1 levels associated with tumor necrosis factor-alpha-converting enzyme (TACE) activity in endometriosis?
UNASSIGNED
Here we provide the first functional evidence that induced TACE activity in human endometriotic epithelial cells is at least in part
Hepatocyte growth factor activator inhibitors (HAI-1 and HAI-2) are Kunitz-type serine protease inhibitors that have a broad inhibitory spectrum against serine proteases. This study examined the role of HAI-1 and HAI-2 in uterine leiomyosarcoma (LMS) patients, and in vitro. HAI-1 and HAI-2 was
Uterine leiomyomas are the most common benign smooth muscle tumors in the myometrium. The expression of redox factor 1 (Ref-1), a DNA repair enzyme and redox-modifying factor, was studied in the myometrium and uterine smooth muscle tumors to investigate the relevance of Ref-1 in the growth
