STAT3 increases the amount of MMP9. 10 / 40
| 37

reach
"34 In a number of other human brain tumor cell lines, stimulation with IL-6, leukemia inhibitory factor, ciliary neurotrophic factor, or OSM induced STAT3 activation, 35 and treatment of human astrogl[MISSING/INVALID CREDENTIALS: limited to 200 char for Elsevier]"

reach
"The enhanced activation of STAT3 in neutrophils can promote the expression and release of MMP-9, and reduce the expression of TRAIL and the release of NE [XREF_BIBR]."

reach
"MMP9 is an important effector molecular in STAT3 pathway [19], and STAT3 activation can increase MMP9 expression, resulting in extracellular matrix (ECM) degradation in the tumor microenvironment [20][MISSING/INVALID CREDENTIALS: limited to 200 char for Elsevier]"

reach
"It has also been reported that STAT3 modulates the expression of MMP-2 and MMP-9, which help in metastasis and angiogenesis."

reach
"STAT3 knockdown inhibited the expression of cyclin D1, cyclin D2, cyclin D3, MMP-2, and MMP-9 in both cell lines, confirming that EtOH increases the proliferation in breast cancer cells through STAT3 activation with an increased expression of cyclins and MMPs."

reach
"We showed that STAT3 overexpression promoted EMT (epithelial-mesenchymal transition) with increased matrix metalloproteinase (MMP)-2 and MMP9 expression."

reach
"In this study, we showed that p-STAT3 directly interacts with a GAS element in MMP-9 gene promoter to drive gene expression of MMP-9."

reach
"Suppression of JAK2 and STAT3 pathway by AG490 attenuated the promotive effects of IL-9 on SMMC-7721 cells, and reduced the expression of VEGF, MMP-2 and MMP-9."

reach
"Furthermore, KYZ3 inhibited TNBC cell metastasis by decreasing the levels of MMP-9 which were directly regulated by activated STAT3."

reach
"In addition, STAT3 activation has been demonstrated to increase the transcription of matrix metalloproteinase-9 (MMP-9), MMP-2, focal adhesion kinase (FAK) and fascin-1, which are well-known pro-invasive factors in GBs [44]."
Modified STAT3 increases the amount of MMP9. 3 / 3
| 3

reach
"A number of studies have demonstrated that the expression of activated STAT3 modulated metastasis of tumor cells by promoting gene transcription of MMP2 and MMP9."

reach
"Stable expression of active STAT3 increased matrix metalloproteinase MMP-9 mRNA levels in MCF-7 cells, indicating that it too is regulated by STAT3."

reach
"Constructive expression of STAT3 can up-regulate the expression of MMP-2 and MMP-9, which are able to efficiently degrade the extracellular matrix and basement membrane, promoting invasion and metastasis of cancer cells."
Phosphorylated STAT3 increases the amount of MMP9. 2 / 2
| 2

reach
"HES1 was reported to enhance the phosphorylation of signal transducers and activators of transcription-3 (STAT3) by binding to STAT3 directly, and phosphorylated STAT3 can elevate MMP2 and MMP9 expression by directly binding to their promoters XREF_BIBR - XREF_BIBR."

reach
"During efficacy testing of hydrazinocurcumin (HC), a synthetic curcumin analogue, inhibition of STAT3 phosphorylation in BC cell lines (MDA-MB-231, MCF-7) decreased the expression of c-Myc, Bcl-xL, Bcl-2, Mcl-1, cyclin D1/D2, VEGF, MMP-2, and MMP-9 among others."
Transcriptionally active STAT3 increases the amount of MMP9. 1 / 1

"and it induces the expression of genes that are involved in invasion and metastasis, such as the matrix metalloproteinase 9 (MMP9) [29]."
