Metastasis is the main cause of death in breast cancer patients. Inflammatory processes following crosstalk between tumor cells and tumor microenvironment play an important role in progression and metastasis of cancer. Hence, targeting of these interactions may represent a novel promising strategy for breast cancer therapy. So, we investigated the effects of β-D mannuronic acid (BDM), a new ant...

Background/purpose The aim of this study was to test the hypothesis that mechanical ventilation (MV) during cancer surgery induces lung stroma/tissue milieu changes, creating a favorable microenvironment for postoperative lung metastatic tumor establishment. Materials and methods In Protocol A, female BALB/c mice were divided into an MV group and a control (no MV) group, both of which were an...

background: the 4t1 cells tumor growth and metastatic pattern in balb/c mice very closely mimic human breast cancer. these herbal remedies used in traditional folk medicine have been the source of many medically beneficial drugs. the aim of the current study was to evaluate the anti-proliferative activity of the asafoetida, ginseng and fennel ethanolic extracts on mouse breast cancer 4t1 cell-l...

Advanced tumors produce an excessive amount of transforming growth factor β (TGFβ), which promotes tumor progression at late stages of malignancy. The purpose of this study was to develop anti-TGFβ therapeutics for cancer. We synthesized a novel small-molecule TGFβ receptor I kinase (activin receptor-like kinase 5) inhibitor termed N-[[4-([1,2,4]triazolo[1,5-a]pyridin-6-yl)-5-(6-methylpyridin-2...

Doxorubicin is used to treat numerous types of tumors including breast cancer, yet dose-associated toxicities limit its clinical application. Here, we demonstrated a novel strategy by which to deliver doxorubicin to breast cancer cells by conjugating cancer cell-specific single-strand DNA aptamers with doxorubicin-encapsulated DOTAP:DOPE nanoparticles (NPs). We utilizing a whole-cell-SELEX stra...

Liposomal doxorubicin (Lipo-DOX) has been widely and successfully used in chemotherapy for breast cancer patients. Since our previous studies found that 188Rhenium (188Re)-N,N-bis (2-mercaptoethyl)-N',N'-diethy-lethylenediamine (BMEDA)-labeled pegylated liposomes (188Re-liposomes) have radiotherapeutic potential in a colon cancer model, and little information is available to make a comparison o...

Skeletal muscle is rich in lymphatic vessels, with an abundant blood supply, and it is an infrequent site of cancer metastasis. Previous studies have demonstrated that enhanced secretion of MyoD may occur when skeletal muscle is injured or becomes cancerous. It was hypothesized that MyoD may act as an endogenous cytokine to inhibit the proliferation of cancer cells. To verify the possible effec...

The therapy of breast cancer is encumbered by drug resistance and metastasis, which can be due to a defective PI3K/AKT/mTOR signaling pathway. This study was aimed at improving the anti-cancer effect of the chemotherapeutic agent paclitaxel (PTX) on the drug resistant and metastatic breast cancer by co-delivering PTX and a siRNA, siAkt, directed at silencing the Akt expression. Methods: The pH-...

Angiogenesis and lymphangiogenesis are considered to play key roles in tumor metastasis. Targeting receptor tyrosine kinases essentially involved in the angiogenesis and lymphangiogenesis would theoretically prevent cancer metastasis. However, the optimal multikinase inhibitor for metastasis suppression has yet to be developed. In this study, we evaluated the effect of NSTPBP 0100194-A (194-A),...
