Apoptogen Inc api2 construct
The fusion constructs Fus1 and Fus2 activate NF-κB in a luciferase promoter assay. 293 cells were transfected in triplicate with pcDNA3, pcDNA3-Fus1, pcDNA3-Fus2, pcDNA3-Del, <t>pcDNA3-API2,</t> or pcDNA3-MALT1 in the presence of pTK-Luc (an NF-κB responsive luciferase reporter) and pEF1-BOS-β-gal (used as a control for transfection efficiency). Strong activation of NF-κB levels was observed with the Fus 1 and Fus 2 constructs. However, the MALT1 full-length cDNA and the Del 1 construct failed to activate NF-κB. As expected, the pcDNA3-API2 full-length construct slightly activated NF-κB.

Article Snippet: To inhibit AKT, mice received intraperitoneal (i.p.) injections of API-2 (HY-15457, MCE, USA) at a dose of 2 mg/kg every 48 h. To inhibit TGFβ, mice received i.p. injections of SB431542 (HY-10431, MCE, USA), a TGFβR1 inhibitor, at a dose of 10 mg/kg every 48 h. To inhibit cAMP, mice received i.p. injections of SQ22536 (HY-100396, MCE, USA), an adenylate cyclase (AC) inhibitor, at a dose of 10 mg/kg every 48 h. To inhibit HO-1, mice received i.p. injections of HO-1i (HY-111798A, MCE, USA) at a dose of 1.357 mg/kg every 48 h. To inhibit intracellular free Ca 2+ , mice received i.p. injections of diltiazem (HY-B0632, MCE, USA) at a dose of 20 mg/kg every 48 h. To inhibit reactive oxygen species (ROS), mice received daily topical application of 100 mg/mL ascorbic acid (HY-B0166, MCE, USA), applied to the skin 30 min after red light exposure.
