ABT-510 acetate is an anti-angiogenic TSP peptide (Thrombospondin-1 analogue) that induces apoptosis and inhibits ovarian tumour growth in an orthotopic, syngeneic model of epithelial ovarian cancer. ABT-510 acetate also reduces angiogenesis and inflammatory responses in a murine model of inflammatory bowel disease. ABT-510 acetate can be used in studies of cancer (particularly epithelial ovarian cancer) and inflammatory bowel disease (IBD).

Description

ABT-510 acetate is an anti-angiogenic TSP peptide (Thrombospondin-1 analogue) that induces apoptosis and inhibits ovarian tumour growth in an orthotopic, syngeneic model of epithelial ovarian cancer. ABT-510 acetate also reduces angiogenesis and inflammatory responses in a murine model of inflammatory bowel disease. ABT-510 acetate can be used in studies of cancer (particularly epithelial ovarian cancer) and inflammatory bowel disease (IBD)[1][2].

In Vitro

ABT-510 acetate (1, 5, 10, 20, 50 nM; 24 h) induces apoptosis in ID8 cells and increases the incidence of apoptosis in the human epithelial cancer cell lines SKOV3, OVCAR3, and CAOV3[1].
ABT-510 acetate (0-10 μM; 7 days) inhibits NO-stimulated vascular cell outgrowth into and invasion through extracellular matrix. ABT-510 acetate blocks tumor-driven vascular cell outgrowth, NO-driven cGMP flux, and CD36-mediated fatty acid uptake. [3].

Apoptosis Analysis[1]

Cell Line: ID8, SKOV3, OVCAR3, and CAOV3 cells
Concentration: 1, 5, 10, 20, 50 nM
Incubation Time: 24 h
Result: Induced ID8 cells apoptosis and increased in apoptosis in the human EOC cell lines SKOV3, OVCAR3, and CAOV3.

Cell Proliferation Assay[3]

Cell Line: Tissue biopsies of B16F10 melanoma tumors grown in C57BL/6 mice
Concentration: 0-10 μM
Incubation Time: 7 days
Result: Inhibited NO-stimulated vascular cell outgrowth into and invasion through extracellular matrix.
In Vivo

ABT-510 acetate (100 mg/kg; i.p.; single daily for 90 days) induces cells apoptosis in vivo and leads to a significant reduction in epithelial ovarian tumor size, ascites fluid volume, and secondary lesion dissemination in mice[1].
ABT-510 acetate (60 mg/kg; osmotic minipumps for s.c.; single daily for 7 days) decreases angiogenesis and inflammation in a murine model of inflammatory bowel disease[2].

Animal Model: TSP-1-Null mice (C57BL/6 background; orthotopic, syngeneic model of epithelial ovarian cancer)[1]
Dosage: 100 mg/kg
Administration: Intraperitoneal injection; single daily for 90 days
Result: Reduced ovarian tumor growth in wild-type and TSP-1-Null Mice.
Significantly reduced the volume of ascites and completely abolished the formation of peritoneal lesions.
Reversed ovarian tumor hypervascularization and increased the proportion of mature blood vessels.
Animal Model: TSP-1-Null mice (C57BL/6 background; 6-week-old; DSS-induced inflammatory bowel disease murine model)[2]
Dosage: 60 mg/kg
Administration: Subcutaneously implanted osmotic minipumps (0.5µL/h); single daily for 7 days
Result: Significantly delayed DSS-induced bleeding and improved the overall severity of disease.
Significantly diminished inflammation grading and angiogenesis.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
