Positron Emission Tomography Studies of the Biodistribution, Translocation, and Fate of Poly Allyl Amine ‐Based Carriers for Sirna Delivery by Systemic and Intratumoral Administration.
Positron emission tomography is used to study the fate of polyplexes formed by siRNA and modified polyamines. Polyplexes are prepared with either radiolabeled siRNA or radiolabeled polyamines. By comparing biodistribution patterns of labeled siRNA and labeled polyamines conclusions are driven on the stability of the polyplexes in vivo. AbstractPolyamine-based vectors offer many advantages for gene therapy, but they are hampered by a limited knowledge on their biological fate and efficacy for nucleic acid delivery. The18F radiolabeled siRNA is complexed with poly(allyl amine) hydrochloride (PAH), PEGylated PAH (PAHPEG), or ...

Correlation between S100A11 and the TGF- β1/SMAD4 pathway and its effects on the proliferation and apoptosis of pancreatic cancer cell line PANC-1.
Correlation between S100A11 and the TGF-β1/SMAD4 pathway and its effects on the proliferation and apoptosis of pancreatic cancer cell line PANC-1. Mol Cell Biochem. 2018 Jun 19;: Authors: Ji YF, Li T, Jiang F, Ni WK, Guan CQ, Liu ZX, Lu CH, Ni RZ, Wu W, Xiao MB Abstract S100A11 as a S100 protein family member has been documented to play dual-direction regulation over cancer cell proliferation. We explored the role of S100A11 in the proliferation and apoptosis of pancreatic cancer cell line PANC-1 and the potential mechanisms involving the TGF-β1/SMAD4/p21 pathway. S100A11 and TGF-β1 protein express...
