Comprehensive analysis of stearoyl-coenzyme A desaturase in prostate adenocarcinoma: insights into gene expression, immune microenvironment and tumor progression.

Prostate adenocarcinoma (PRAD) is a prevalent global malignancy which depends more on lipid metabolism for tumor progression compared to other cancer types. Although Stearoyl-coenzyme A desaturase (SCD) is documented to regulate lipid metabolism in multiple cancers, landscape analysis of its implications in PRAD are still missing at present. Here, we conducted an analysis of diverse cancer datasets revealing elevated expression in the PRAD cohort at both mRNA and protein levels.

Drug- and Gene-eluting Stents for Preventing Coronary Restenosis.

Coronary artery disease (CAD) has been reported to be a major cause of death worldwide. Current treatment methods include atherectomy, coronary angioplasty (as a percutaneous coronary intervention), and coronary artery bypass. Among them, the insertion of stents into the coronary artery is one of the commonly used methods for CAD, although the formation of in-stent restenosis (ISR) is a major drawback, demanding improvement in stent technology.

Therapeutic Effect of Akt1 siRNA Nanoparticle Eluting Coronary Stent on Suppression of Post-Angioplasty Restenosis.

For effective treatment of restenosis, therapeutic genes are delivered locally from a coated stent at the site of injury, leading to inhibition of smooth muscle proliferation and neo-intimal hyperplasia while promoting re-endothelialization. In a previous study, we delivered Akt1 siRNA nanoparticles (ASNs) from a hyaluronic acid (HA)-coated stent surface to specifically suppress the pro-proliferative Akt1 protein in smooth muscle cells (SMCs). In the present study, therapeutic efficacy was investigated in a rabbit restenosis model after percutaneous implantation of an ASN-immobilized stent in a rabbit iliac artery.
