ANGPTL7

Recombinant canine ANGPTL7 (E2R2G1) (Met1-Pro344) was expressed with the Fc region of human IgG1 at the C-terminus.

ANGPTL7 is a member of the Angiopoietin-like (ANGPTL) protein family that is composed of eight proteins (1-8). Increasing evidence is associating ANGPTL proteins to obesity and insulin resistance. Obesity increases the level of ANGPTL7 in both plasma and adipose tissue. Increased expression of ANGPTL7 might play a minor role in the regulation of TG level in obese subjects either directly or through interaction with other ANGPTL protein members. Physical exercise reduced the level of ANGPTL7 highlighting the potential for targeting this protein as a therapeutic target for regulating dyslipidemia. Angptl7 is a factor that promotes pro-inflammatory responses in macrophages through the P38 MAPK signaling pathway and represents a potential therapeutic target for treatment of inflammatory diseases. Expression of ANGPTL7 (angiopoietin-like 7), a protein not previously linked to metastasis, was highly up-regulated in cancer cells after myeloid cell depletion. This effect was duplicated in tissue culture, where coculture of cancer cells with tumor-conditioned myeloid cells from liver metastases or myeloid cell conditioned media down-regulated ANGPTL7 expression. Analogous to myeloid cell depletion, overexpression of ANGPTL7 in cancer cells significantly reduced hepatic metastasis formation and angiogenesis. We found that ANGPTL7 itself has strong antiangiogenic effects in vitro. Furthermore, analysis of The Cancer Genome Atlas colorectal and breast cancer data sets revealed striking ANGPTL7 underexpression in cancerous compared to normal tissues. Also, ANGPTL7 was down-regulated in metastatic liver colonies of colorectal cancer patients compared to their adjacent liver tissue.The secreted growth factor ANGPTL7 as a regulator of both human hematopoietic stem and progenitor cell expansion and regeneration.
