NFκB induces overexpression of bovine FcRn

Overexpression of Bovine FcRn in Mice Enhances T-Dependent Immune Responses by Amplifying T Helper Cell Frequency and Germinal Center Enlargement in the Spleen

The neonatal Fc receptor (FcRn) plays key roles in IgG and albumin homeostasis, maternal IgG transport, and antigen presentation of IgG-opsonized antigens. Previously, we reported that transgenic (Tg) mice that overexpress the bovine FcRn (bFcRn) have augmented T-dependent humoral immune response with increased IgG protection, higher level of antigen-specific antibodies, greater number of antig...

Systemic Overexpression of IL-10 Induces

Overexpression of endocan induces tumor formation.

Endocan is a proteoglycan specifically secreted by endothelial cells. Through its glycan domains, endocan binds to hepatocyte growth factor and increases its mitogenic activity. Here, we show that human embryonic kidney 293 cells, which have been genetically engineered to overexpress endocan, form tumors when injected s.c. in SCID mice. Both the glycan and a phenylalanine-rich region of endocan...

Bovine FcRn-Mediated Human Immunoglobulin G Transfer across the Milk-Blood Barrier in Transgenic Mice

Maternal-fetal IgGs transport occurs either prenatally or postnatally, which confers the newborns with passive immunity before their own immune system has matured. However, little is known about the mechanisms of postnatal IgGs passage in the mammary gland. To investigate how FcRn mediates the IgGs transport in the mammary gland, we first generated bFcRn and anti-HAV mAb transgenic mice, and th...

Overexpression of MiR-138 Inhibits Cell Growth and Induces Caspase-mediated Apoptosis in Acute Promyelocytic Leukemia Cell Line

Dysregulated expression of miRNAs can play a vital role in pathogenesis of leukemia. The shortened telomere length, and elevated telomerase activity in acute promyelocytic leukemia cells are mainly indicative of extensive proliferative activity. This study aimed to investigate the effect of overexpression of miR-138 on telomerase activity, and cell proliferation of acute promyelocytic leukemia ...
