Expression of gelatinases and tissue inhibitors of metalloproteinases in the rhesus monkey (Macaca mulatta) corpus luteum
Matrix metalloproteinases (MMPs) and their tissue inhibitors (TIMPs) are believed to play important roles in the formation and regression of corpus luteum (CL). This study is to investigate the expression of g...

Effect of UPP on the expression of VEGF and its receptors in mouse uterus during peri-implantation
On day 3 of gestation, one uterine horn of female pregnant mouse was injected intraluminally with 5 µL 0.1 µg/mL lactacystin, a specific inhibitor of ubiquitin-proteasome pathway (UPP), while the contralateral...

Direct observation of catch bonds involving cell-adhesion molecules
Bonds between adhesion molecules are often mechanically stressed. A striking example is the tensile force applied to selectin–ligand bonds, which mediate the tethering and rolling of flowing leukocytes on vasc...
