This virus apparently generated an even higher level of peak hemolymph ecdysteroid titer (1162 ± 476 versus 724 ± 194 pg μl−1) in comparison to a control virus that expressed PTTH but retained a normal egt gene. This higher ecdysteroid peak, however, was delayed by about 48 h ...
TEM images were collected at the USC Core Center of Excellence in Nano Imaging, and qTOF analysis was performed at the USC Chemistry Mass Spectrometry Core and the Agilent Center of Excellence in Biomolecular Characterization. Some computational resources used for structure determination were provided ...
GOx was introduced to decrease the ATP level thus alleviating the HSPs-mediated heat tolerance, while the loaded MnO2 could decompose intratumoral H2O2 into O2, which enhanced the effect of HPTT and ST. Due to the coated HA, UMIGH could target the high expressed CD44 in CT26 tumor cells. ...
Emerging research evidence indicates that O-GlcNAcylation is globally elevated in various cancers, but the mechanisms involved in the tumor pathology remain incompletely understood at the molecular level14,15. PGK1, the first ATP-generating enzyme in glycolysis, catalyzes the conversion of 1,3-di...
The overall mechanism of quinol oxidation by the bc1 complex is well enough characterized to allow exploration at the atomistic level, but details are still highly controversial. The controversy stems from the uncertain binding motifs of quinol at the so-called Qo active site of the bc1 complex...

The availability of free estrone on the cellular level depends on the expression of STS and/or SULT, which catalyze the sulfation of the phenolic hydroxy function. On the other hand, estrone sulfate is not able to cross the cell membrane passively; therefore, a carrier is needed to mediate ...

Therefore, the level of O-GlcNAcylation is dynamically regulated by an interplay between OGT and OGA, in concert with nutrient availability, cellular stress, and metabolic status of the cell. It is striking that only a single pair of enzymes, OGT and OGA, is responsible for O-GlcNAc cycling ...
