6-Shogaol and 6-gingerol effectively inhibit invasion and metastasis of hepatocellular carcinoma through diverse molecular mechanisms, including inhibition of the MAPK and PI3k/Akt pathways and NF-κB and STAT3 activities to suppress expression of MMP-2/-9 and uPA and block angiogenesis.
Urokinase-type plasminogen activator (uPA) plays a central role in many aspects of cellular regulation, such as fibrinolysis, cell migration, and metastasis.
Urokinase-type plasminogen activator (uPA) is believed to play a key role in tissue degradation and cell migration under various normal and pathological conditions, including cancer invasion and metastasis.
Urokinase-type plasminogen activator (uPA) is a member of the serine protease family and can break down various components of the extracellular matrix to promote growth, invasion, and metastasis of several malignancies including breast cancer.
Urokinase-type plasminogen activator (uPA), its receptor (uPAR) and its inhibitor PAI-1, play a key role in tumor invasion and metastasis. uPA and PAI-1 were the first novel tumor biological factors to be validated at the highest level of evidence regarding their clinical utility in breast cancer.
Urokinase-type plasminogen activator (uPA) is a serine protease that is involved in cancer progression, especially invasion and metastasis including prostate cancer. uPA activation is mediated by transactivation of uPAR and epidermal growth factor receptor (EGF-R) in prostate cancer progression.
Urokinase type plasminogen activator (uPA) is a serine protease that is involved in cancer progression, especially invasion and metastasis of breast cancer.
Adip-CM, but not PreAdip-CM, (a) increased cell motility in both MCF-10A and MCF-10CA1 cells; (b) increased cell-associated uPA activity in both cell lines; (c) increased phosphorylated-Akt levels in MCF-10CA1 cells; and (d) gene array profiles show altered expression of several genes associated with cancer adhesion, metastasis and signaling.
Angioinvasion is critical for metastasis with urokinase-type plasminogen activator receptor (uPAR) and tumor hypoxia-activated hypoxia-inducible factor 1 (HIF-1) as key players.
As uPA can be involved in cancer invasion and metastasis, C/C genotype in exon 6 of uPA gene can be further considered as being related to colorectal cancer progression.
Because beta-catenin and its target genes urokinase-type plasminogen activator receptor (uPAR) and cyclin D1 are overexpressed in colon cancers, and are linked to cancer growth, invasion, and metastasis, we investigated whether DCA activates beta-catenin signaling and promotes colon cancer cell growth and invasiveness.
Because uPA expression is strongly correlated with its hypomethylated state, we utilized the uPA gene in the highly invasive MDA-231 human breast cancer cells as a model system to test the hypothesis that pharmacological reversal of the uPA promoter hypomethylation would result in its silencing and inhibition of metastasis.
Both the urokinase-type plasminogen activator (uPA) and the uPA receptor (uPAR) play important roles with regard to hepatocellular carcinoma (HCC) progression and metastasis.
BRMS1 forms complexes with SIN3, histone deacetylases and selected transcription factors that modify metastasis-associated gene expression (e.g., EGFR, OPN, PI4P5K1A, PLAU). microRNA (miRNA) are a recently discovered class of regulatory, noncoding RNA, some of which are involved in neoplastic progression.
By comparing the two groups, u-PA and VEGF were positively correlated in gastric cancer tissue (P < 0.05). u-PA and VEGF were highly expressed in gastric cancer tissue, which could be used as the molecular biological indicators to predict the invasion and metastasis potential of gastric cancer.
C4.4A, a structural homologue of the urokinase-type plasminogen activator receptor (uPAR), was originally identified as a metastasis-associated membrane protein, but little is known about its structural and functional properties.
Cancer invasion and metastasis are highly complex processes and a serine protease urokinase-type plasminogen activator/urokinase-type plasminogen activator receptor system has been postulated to play a central role in the mediation of cancer progression.
CPL also down-regulated the expression of urokinase type plasminogen activator (uPA), one of key proteins associated with invasion and metastasis of tumor cells in a concentration dependent fashion, while CPL didn't significantly affect the expression of matrix metalloproteinase 2 (MMP-2) and tissue inhibitor of metalloproteinase 2 (TIMP-2) by reverse transcriptase-polymerase chain reaction (RT-PCR).
DNA methylation specific real-time polymerase chain reaction (PCR) (Methylight®) was employed to document the methylation status of the metastasis-relevant urokinase-type plasminogen activator (uPA) and plasminogen activator inhibitor-I (PAI-1) genes.
