A mini-peptide and its analogs have been found to target gene products to tumors. The peptide, named Carcinoma Homing Peptide (CHP), increased the tumor accumulation of the reporter gene products in five independent tumor models, including one human xenogeneic model. A CHP-IL-12 fusion gene was also developed using CHP and the p40 subunit of IL-12. The product from CHP-IL-12 fusion gene therapy increased accumulation of IL-12 in the tumor environment. In three tumor models, CHP-IL-12 gene therapy inhibited distal tumor growth. In a spontaneous lung metastasis model, inhibition of metastatic tumor growth was improved compared to wild-type IL-12 gene therapy, and in a squamous cell carcinoma model, toxic liver lesions were reduced. The receptor for CHP was identified as vimentin. CHP can be used to improve the efficacy and safety of targeted cancer treatments.

Angiopoietin-like 4 and its use in modulating cell leakiness
Vascular disruption induced by interactions between tumor-secreted permeability factors and adhesive proteins on endothelial cells facilitates metastasis. The role of tumor secreted angiopoietin-like 4 (cANGPTL4) in vascular leakiness and metastasis is controversial due to the lack of understanding of how cANGPTL4 modulates vascular integrity. Here, we show that cANGPTL4 instigated the disruption of endothelial continuity by directly interacting with three novel binding partners, integrin [alpha]5[beta]1, VEcadherin and claudin-5, in a temporally sequential manner, thus facilitating metastasis. We showed that cANGPTL4 binds and activates integrin [alpha]5[beta]1-mediated Rac1 / PAK signaling to weaken cell-cell contacts. Subsequently, cANGPTL4 is associated with and declusters VE-cadherin and claudin-5, leading to endothelial disruption. Interfering with the formation of these cANGPTL4 complexes delayed vascular disruption. In vivo vascular permeability and metastatic assays performed using ANGPTL4-knockout and wild-type mice injected with either control or ANGPTL4-knockdown tumors confirmed that cANGPTL4 induced vascular leakiness and facilitated lung metastasis in mice. Therefore, our findings elucidate how cANGPTL4 induces endothelial disruption. Our findings have direct implications for targeting cANGPTL4 to treat cancer and other vascular pathologies.

The invention belongs to the technical field of medical products, and discloses an application to promotion of squamous cell carcinoma metastasis based on DDX19A. In function, DDX19A is found to promote in-vitro migration and invasion of cervical squamous cell carcinoma cells and in-vivo lung metastasis. In terms of mechanism, overexpression of the DDX19A increases NOX1 expression, increases production of reactive oxygen species (ROS), and induces migration and invasion of the cervical squamous cell carcinoma cells. Rescue experiments show that overexpression of NOX1 can retrieve and knock down cervical cancer squamous cell carcinoma cell invasion and migration and ROS generation caused by DDX19A, and the inventor further discovers that an ROS inhibitor N-acetylcysteine can inhibit DDX19A-induced cervical squamous cell carcinoma cell invasion and migration. Therefore, the DDX19A is proved to promote metastasis of the cervical squamous cell carcinoma by inducing NOX1 to mediate ROS production. Blocking of a DDX19A / NOX1 / ROS axis can be a potential therapeutic target for patients with cervical squamous cell carcinoma.

The present invention relates to a method and composition for treating melanoma, aggressive / invasive melanoma, metastatic melanoma or melanoma resistant. More particularly, inventors have shown that high expression of PTX3 correlates with melanoma invasiveness and with a poorer survival rate in metastatic melanoma patients. PTX3 knockdown inhibited melanoma cell migration, invasion, lung metastasis, and NFκB signaling pathway. An addition of melanoma-derived or recombinant PTX3, or overexpression of PTX3 enhanced motility of low migratory cells. Finally, they found that TLR4 and MYD88 knockdown or targeting inhibited PTX3-induced melanoma cell migration, suggesting that PTX3 functions through a TLR4 / NFκB-dependent pathway. Accordingly, the invention relates to a method for predicting the survival time of a subject suffering from melanoma, aggressive / invasive melanoma, metastatic melanoma or melanoma resistant by quantifying the expression level of PTX3 in a biological sample and to a method of treating melanoma, aggressive / invasive melanoma, metastatic melanoma or melanoma resistant by using the inhibitors of PTX3.
