MMP11 depletion severely impaired LUAD cell proliferation, migration, and invasion <i>in vitro</i>, in line with retarded tumor growth in xenograft models.
The present study therefore demonstrated that IGF-1-induced MMP-11 may have facilitated the proliferation and invasion of SGC-7901 cells via the JAK1/STAT3 pathway.
The genomic expression of 20 stroma-derived factors, including the androgen receptor (AR), growth factors (FGF2, FGF7, FGF10, HGF, TGFβ, PDGFB), protein implicated in invasion (MMP-2, MMP-9 and MMP-11), inflammation (IL-6, IL-17, STAT-3 and NFκB), stroma/epithelium interaction (CDH11, FAP, CXCL12 and CXCL14) and chaperones (HPA1A and HSF1), was evaluated in cultured fibroblasts both from BHP and prostate carcinomas (PCa).
The present study also demonstrated for the first time, to the best of our knowledge, that miR‑145 may directly target matrix metallopeptidase‑11 (MMP‑11) in RCC. miR‑145 was demonstrated to suppress cell proliferation, migration and invasion by targeting MMP‑11 in RCC cell lines.
However, it remains unknown whether transcription regulation of matrix metalloproteinase-11(MMP-11) and cytoskeleton-20 (CK-20) genes for the homoeostasis of epithelial/connective interface that can enhance cell dissemination and invasion may act as alternative mutators to tumor clinicopathology.
Statistically significant associations were found in the invasive carcinomas between ST-3 expression and lymphatic vessel invasion, an infiltrative invasive pattern, and invasion into at least the muscle layer (pT2,3,4 v pT1).
By Northern blot analysis, levels of ST-3 mRNA were significantly increased in the carcinomas compared with ST-3 expression was seen with degree of invasion, nodal or distant metastases, or histologic grade.
Our finding of ST-3 mRNA overexpression in 17 of 19 (89%) BCC specimens is consistent with a role for this molecule in local invasion of stroma by BCC.
There was no significant correlation between stromelysin-3 expression and other prognostic factors, including tumor size, lymph-node involvement, age of patient, vascular invasion and cathepsin-D.
Therefore, expression of stromelysin 3 in stromal cells may be expected to play a significant role in destruction of the basal membrane zone and extracellular matrix in basal cell carcinoma invasion.
