Collectively, our data indicate that circular matrix metalloproteinase 9 acts as a metastasis-promoting gene in oral squamous cell carcinoma through regulating the messenger RNA stability of its parental gene.
Glycogen synthase kinase-3β mediated regulation of matrix metalloproteinase-9 and its involvement in oral squamous cell carcinoma progression and invasion.
We found a higher expression of MMP-9 [OR, 4.2; 95% confidence interval (CI), 2.2-7.8] and lower expression of RECK (OR, 0.4; 95% CI, 0.2-0.7) in women with CIN2/CIN3/SCC when compared with women from the control group (no neoplasia/CIN1).
To investigate whether calcipotriol could suppress the expression of MMP-9 and MMP-13 in a human squamous cell carcinoma (SCC) cell line (DJM cells), and to examine the mechanism of modulation of MMP-9 and MMP-13 by calcipotriol in DJM cells treated with tumour necrosis factor (TNF)-α.
The correlation of the expression of MMP9 and CD147 with invasion and metastasis of invasive squamous cell carcinoma (SCC) of the uterine cervix has not been examined.
MMP9 expression levels were particularly high in endobronchial lining fluid samples collected from patients with squamous cell carcinoma but not elevated in the case of benign lesions.
In this study, panduratin A, a natural bioactive compound isolated from Kaempferia pandurata ROXB., was used to test its in vitro inhibitory activity against MMP-9 secretion from Porphyromonas gingivalis supernatant-induced human oral epidermoid carcinoma KB cells.
Furthermore, EPS8 expression in clinical samples of squamous cell carcinoma showed variable expression levels and broadly paralleled expression of MMP-9.
Because transforming growth factor beta1 (TGF-beta1) is up-regulated in OSCC tumors, we examined the relationship between TGF-beta1 signaling and MMP-9 in human OSCC specimens.
Functional -1562 C-to-T polymorphism in matrix metalloproteinase-9 (MMP-9) promoter is associated with the risk for oral squamous cell carcinoma in younger male areca users.
All EBER-positive SCCs were infected with EBV type A. LMP1 expression was detected in 36 of 59 (61%) patients with latent EBV infection and MMP9 in 41 of these 59 (69%).
Integrin alphavbeta6 is induced in SCC and appears to be involved in up-regulation of MMP-9 expression by oral keratinocytes and promotion of their migration.
