Small molecules not only represent cellular building blocks and metabolic intermediates, but also regulatory ligands and signaling molecules that interact with proteins. Although these interactions affect cellular metabolism, growth, and development, they have been largely understudied. Herein, we d...

Background: Pachymic acid (PA) is a purified triterpene extracted from medicinal fungus Poria cocos. In this paper, we investigated the anticancer effects of PA on human chemotherapy resistant pancreatic cancer cells. Methods: Gemcitabine-resistant pancreatic cancer cells PANC-1 and MIA PaCa-2 were...

The non-coding transcriptome of the hyperthermophilic archaeon Pyrococcus abyssi is investigated using the RNA-seq technology. A dedicated computational pipeline analyzes RNA-seq reads and prior genome annotation to identify small RNAs, untranslated regions of mRNAs, and cis-encoded antisense transc...

We combined pulsed stable isotope labeling of amino acids (pSILAC) with enrichment of phosphorylated peptides in a method we term PhosphoProtein-Peptide Turnover Profiling (PhosphoPPToP). We applied the method to HeLa cells to find peptides whose clearance rates differ from the protein median. Using...

The stress-activated protein kinase Hog1 is best known for its role in osmotic stress but is also activated by a variety of mechanistically distinct environmental stressors including heat shock, ER stress, and arsenic. In the osmotic stress response, the signal is sensed upstream and relayed to Hog1...

The hippocampus plays an important role in spatial memory and the conversion of short-term to long-term memory. Several studies have reported the presence of a peripheral oscillator in the hippocampus, and have highlighted the importance of circadian regulation in memory formation. In this study we ...
