The stimulation of adenosine 2A receptor reduces inflammatory response in mouse articular chondrocytes treated with hyaluronan oligosaccharides The adenosine 2A receptor A 2A R is greatly involved in inflammation pathologies such as rheumatoid arthritis.
Physiological changes which lead to diagnosis present as psychomotor dysfunctions, beginning with unprovoked, uncontrollable hyperkinesias referred to as chorea, which progress over several years into ataxic inhibition of voluntary movements and general rigidity, with ultimate mortality largely as a consequence of dysphagia.
The htt gene, encoded on the short arm of the fourth chromosome from codons 3, to 3,, at what is cytogenetically referred to as 4p Microscopic observations have led to the hypothesis that the aggregation of the polyQ peptide due to its polar nature expands to the extent that other proteins with polar surfaces such as CREB binding protein CBP are diverted away from the wild-type cellular function and misfolded, thus inhibiting proper function overall, in conjunction with glutamate-induced excitotoxicity due to the formation of inclusion bodies.
This was proven by transfection of primary cortical neurons with a lentiviral vector expressing the 17Q or Q isoforms of the htt gene, with ballooning-type cell death, similar to transcriptional repression-induced atypical cell death, prevelent in the httQ isoform.RNA interference (RNAi) is an evolutionary regulatory mechanism of most cells that uses ∼21–25 long siRNA transcripts to effectively control the expression of desired genes.
By inhibiting the expression of mRNA transcripts through degrading or binding sequence specifically thus hindering translation into proteins. Hepatocellular carcinoma (HCC) is one of the most common malignancies worldwide.
However, there is no effective treatment for HCC. It has been shown that sustained activation of telomerase is essential for the growth and progression of HCC, suggesting that telomerase is a rational target for HCC therapy.
Here, we investigated the effects of siRNA-mediated knockdown of hTERT, the catalytic and. In the current study, we selected two synthetic transfection reagents, a cationic lipid-based commercial reagent Lipofectamine RNAiMAX and polyethylenimine (PEI), and two naturally-derived transfection reagents, namely the polysaccharides chitosan (98% deacetylation) and hyaluronic acid (20% amidation), for siRNA delivery into primary mesenchymal cells including nucleus pulposus cells, articular .
PLK siRNA displayed potent activity in a range of human cancer cell lines, including LST colon carcinoma and HepG2 and He3B hepatocellular carcinoma cell lines (Figure 1D), that was associated with the dose-dependent induction of apoptosis 48 hours after siRNA transfection (Figure 1E).

Small interfering RNA (siRNA) has attracted attention in the field of nucleic acid medicine as a RNA interference (RNAi) application that leads to gene silencing due to specific messenger RNA (mRNA) destruction. However, since siRNA is unstable in blood and unable to cross the cell membrane, encapsulation of siRNA into a carrier is required.
