生物活性

Kp7-6, a Fas mimetic peptide, is a Fas/FasL antagonist. Kp7-6 protects cells from Fas-mediated apoptosis, and protects mice from Fas-mediated hepatic injury.

体外研究

Kp7-6 (1 h, 0.1-5 mM) can dose dependently inhibit apoptosis of CM cells, RINm5F cells, and isolated mouse pancreatic beta cells induced by human islet amyloid peptide (hA), and has stronger activity in cultured insulinoma cell lines.
Kp7-6 (5 mM) can inhibit the activation of hA induced activated caspase-8, phosphorylated JNK1, and activated caspase-3 in isolated mouse islets when used as a pretreatment or post-treatment.
Kp7-6 (300 μM; 2 h) can effectively inhibit the binding of FasL to Fas receptor in solid-phase ELISA experiments.
Kp7-6 (12.5-100 μM; 300 s) can specifically bind to FasL (Kd=11.2 μM) and Fas (Kd=13.2 μM) with similar affinity.
Kp7-6 (0-1000 μM; 25 h) can dose dependently protect Jurkat cells from FasL induced cytotoxicity, with a cell survival rate of>90% at a concentration of 1000 μM, and no toxicity when acting alone on Jurkat cells.
Kp7-6 (0-1000 μg/mL; 3 h) can dose dependently inhibit FasL induced apoptosis in Jurkat cells.
Kp7-6 (1 mM; 2 h) can activate the NF - κ B signaling pathway (via I κ B α phosphorylation) in Jurkat cells stimulated by FasL, and inhibit the phosphorylation of ERK1/2 without altering the activation level of JNK.

 

Apoptosis Analysis

Cell Line:
CM insulinoma cells, RINm5F insulinoma cells, isolated murine islet β-cells
Concentration: 0.1 mM, 0.5 mM, 1 mM, 5 mM, 10 mM
Incubation Time: 1 hour
Result: Dose-dependently suppressed hA-evoked apoptosis.
Partially but significantly suppressed apoptosis in CM and RINm5F cells at 0.5-1 mM.
Completely suppressed apoptosis in both cell lines at 5 mM.
Exhibited more potent protective effect in cultured cell lines than in isolated islets.
Effectively inhibited apoptosis in all three β-cell systems.
Showed similar rescue effect between cultured cell lines and islet β-cells.

Cell Cytotoxicity Assay

Cell Line: Jurkat cells
Concentration: 10, 100, 1000 μM
Incubation Time: 1 h (preincubation with FasL); 24 h (incubation with cells before [3H]thymidine pulsing)
Result: Showed dose-dependent inhibitory activity against FasL-induced cytotoxicity.
Protected >90% of Jurkat cells from Fas-mediated cytotoxicity at the highest tested concentration.
Did not mediate cytotoxicity to Jurkat cells at the tested concentrations.

Apoptosis Analysis

Cell Line: Jurkat cells
Concentration: 300, 1000 μg/mL
Incubation Time: 3 hours
Result: Dose-dependently reduced the percentage of annexin V-positive apoptotic Jurkat cells treated with FasL.
Reduced apoptotic cells to 31.5% at 300 μg/mL, and to 21.5% at 1000 μg/mL, compared to 49.6% apoptotic cells with FasL alone.

Western Blot Analysis

Cell Line: Jurkat cells
Concentration: 1 mM
Incubation Time: 2 h (preincubation with cells before FasL treatment)
Result: Enhanced phosphorylation of IκBα in the presence of FasL at 5 min.
Significantly inhibited phosphorylation of ERK1/2 at 5-30 min compared to treatment with FasL alone.
Had no effect on JNK activation.
体内研究

Kp7-6 (3 mg per mouse; i.p.); A single dose can significantly alleviate the liver injury induced by ConA in C57BL-6 mice, which can be verified by the decrease in serum ALT and AST activity.
Kp7-6 (100 mg/kg; i.p.; daily administration) can reduce the level of FasL in tumor tissue, increase the infiltration of CD8+Fas+T cells, and significantly reduce the tumor weight of Rip1-Tag2 pancreatic neuroendocrine tumor mice.

 

Animal Model: C57BL-6 (8-week-old)
Dosage: 3 mg per mouse
Administration: i.p.; single dose
Result: Reduced serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities significantly (P < 0.01 vs.
Con A-treated mice).
Animal Model: Rip1-Tag2 (C57BL/6 background; 12 weeks old; spontaneous pancreatic neuroendocrine tumor model)
Dosage: 100 mg/kg
Administration: i.p.; daily
Result: Significantly reduced tumor FasL levels compared to vehicle controls.
Increased infiltration of CD8+Fas+ T cells in tumor tissues compared to vehicle controls.
Significantly decreased tumor weight compared to vehicle controls.
Left ACSS2 expression in tumor tissues unchanged compared to vehicle controls.
