生物活性

REGN7999 is a monoclonal antibody that inhibits TMPRSS6. REGN7999 inhibits TMPRSS6 activity, preventing Hemojuvelin (HJV) lysis, thereby enhancing BMP6-HJV signaling and increasing serum hepcidin. REGN7999 ameliorates iron overload and impaired erythropoiesis in a β-thalassemia mouse model by inhibiting TMPRSS6 activity. REGN7999 is indicated for research in β-thalassemia[1][2].

体外研究
(In Vitro)

REGN7999 在过表达 HJV 和 TMPRSS6 的 HEK293 细胞中可阻断人类和小鼠 TMPRSS6 的活性,IC50 分别为 0.68 和 16 nM,并可阻止 HJV 裂解[2]
REGN7999 可结合 TMPRSS6 并抑制跨物种的 TMPRSS6 活性,降低人类参考和变体 TMPRSS6、食蟹猴 TMPRSS6 以及小鼠 TMPRSS6 的蛋白水解活性[2]

体内研究
(In Vivo)

REGN7999 (10 mg/kg,皮下注射,每周一次,共 12 周) 在 Hbbth3/+ 小鼠模型中可提高血清铁调素水平,降低肝铁含量,恢复红细胞 (RBC) 水平,并改善红细胞健康[1][2]
REGN7999 (5 mg/kg,皮下注射,一次) 可增加 C57BL/6 小鼠模型中的血清铁调素并降低血清铁[2]

MCE has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Hbbth3/+ mice model[1][2]
Dosage: 10 mg/kg
Administration: s.c., once a week, 12 weeks
Result: Reduced liver iron (~50% reduction compared to the isotype-treated group), improved RBC health as determined by reduced annexin V staining and RBC turnover, extend the RBC life span.
Elevated serum hepcidin and hepatic HAMP1 expression, did not increase markers of liver damage.
Reduced spleen weights to WT levels, displayed normalized reticulocyte numbers, blunted the increase in oxidative stress in blood and spleens, reduced bilirubin levels and lower expression levels of hepatic Hmox1, improved anaerobic capacity, increased bone mineral density.
Animal Model: C57BL/6 mice model[2]
Dosage: 5 mg/kg
Administration: s.c., once
Result: Increased serum hepcidin, and decreased in serum iron, led to a significant drop of transferrin saturation and serum iron in the first 24 hours.

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.
