PTD-fusion protein technology was used to transduce heat shock protein 27 (HSP27), an anti-apoptotic protein, into human lens epithelial cells (HLECs) (SRA01/04). The protein transduction domain (PTD) of the 11-amino acid YGRKKRRQRRR was tagged at the N-terminus of HSP27. The fusion protein was purified from bacteria transformed with a pKYB-PTD-HSP27(More)
Pituitary adenylate cyclase-activating polypeptide (PACAP) is a potential therapeutic neuropeptide. The 11-amino acid human immunodeficiency virus TAT protein transduction domain is able to deliver protein cargoes across the cell membrane and the blood-brain barrier. A novel fusion protein PACAP-TAT, containing TAT at the C-terminus of PACAP was therefore(More)
A novel peptide VIP-TAT with a cell penetrating peptide TAT at the C-terminus of VIP was constructed and prepared using intein mediated purification with an affinity chitin-binding tag (IMPACT) system to enhance the brain uptake efficiency for the medical application in central nervous system. It was found by labeling VIP-TAT and VIP with fluorescein(More)
PAC1 is PACAP (pituitary adenylate cyclase-activating polypeptide) preferring receptor belonging to class B G protein coupled receptor (GPCR) mediating the most effects of PACAP. The important role of G protein coupled receptor homo/heteromerization in receptor folding, maturation, trafficking, and cell surface expression has become increasingly evident.(More)
Pituitary adenylate cyclase activating polypeptide (PACAP) is a neuropeptide with cytoprotective ability mediated by its specific receptor PAC1. In this research, firstly the thymus index and the expression of PAC1 in the normal and degenerative thymus with different gender were assayed; secondly PACAP in different dose was used to treat the female mice(More)
Pituitary adenylate cyclase-activating polypeptide (PACAP) is a potential therapeutic peptide with anti-inflammatory and anti-oxidative effects. In order to increase the efficiency of traversing biological barriers, a novel fusion peptide PACAP-TAT was produced by tagging PACAP at its C-terminus with 11-amino acid TAT protein transduction domain. The(More)
The difference between recycled ceramic aggregate concrete (RCAC) and natural aggregate concrete lies in the application of recycled ceramic aggregate (RCA) in the production of concrete. Therefore research on the characteristic of RCA to improve the quality of RCAC is very important. Testing results of physical performance of recycled ceramic coarse(More)
