Antibody fragment (Fab')-installed polyion complex (PIC) micelles were constructed to improve targetability of small interfering RNA (siRNA) delivery to pancreatic cancer cells. To this end, we synthesized a block copolymer of azide-functionalized poly(ethylene glycol) (PEG) and poly(L-lysine) (PLL), and prepared PIC micelles with siRNA. Then, a dibenzylcyclooctyne (DBCO)-modified anti-human tissue factor (TF) Fab' was conjugated to azido groups on the micellar surface. A fluorescence correlation spectroscopic (FCS) analysis revealed that 1, 2, or 3 molecule(s) of Fab'(s) were installed onto one micellar nanoparticle according to the feeding ratio of Fab' (or DBCO) to micelle (or azide)...

Current antifungal drugs suffer from limitations including toxicity, adverse interactions with other commonly prescribed drugs, and the emergence of resistant strains. Here, we repurposed the anthelmintic oxyclozanide as a potent antifungal agent against both sensitive and resistant clinical isolates of Candida albicans, as well as other human opportunistic fungi. Antifungal activity of oxyclozanide was enhanced when C. albicans grew in nonfermentable carbon sources. Our data support a mechanism of action where oxyclozanide uncoupled the mitochondrial electron transport from oxidative phosphorylation and perturbed the mitochondrial membrane potential...

Genetic ablation of the tumor suppressor PTEN in prostatic epithelial cells (PECs) induces cell senescence. However, unlike oncogene-induced senescence, no hyperproliferation phase and no signs of DNA damage response (DDR) were observed in PTEN -deficient PECs; PTEN loss-induced senescence (PICS) was reported to be a novel type of cellular senescence. Our study reveals that PTEN ablation in prostatic luminal epithelial cells of adult mice stimulates PEC proliferation, followed by a progressive growth arrest with characteristics of cell senescence...

Isocyanates are harmful semi-volatile organic compounds that are emitted from various consumer products like polyurethane foam-based mattresses. Although it is a concern that isocyanates might accumulate in indoor dust, causing infants and toddlers, in particular, to be exposed to them, little information is available on the levels of isocyanates in the indoor environment. In this study, we investigated the suitability of an analytical method for determining the presence and level of isocyanates in the indoor dust...

TOR (Target of rapamycin) has been previously implicated in transcriptional stimulation of the ribosomal protein (RP) genes via enhanced recruitment of NuA4 (Nucleosome acetyltransferase of H4) to the promoters. However, it is not clearly understood how TOR enhances NuA4 recruitment to the promoters of the RP genes. Here, we show that TOR facilitates the recruitment of the 19S proteasome subcomplex to the activator to enhance the targeting of NuA4 to the promoters of the RP genes. NuA4, in turn, promotes the recruitment of TFIID (Transcription factor IID that is composed of TBP and a set of TBP-associated factors or TAFs) and RNA polymerase II to the promoters of the RP genes to enhance transcriptional initiation...
