Further, the endogenous levels of phytohormones abscisic acid (ABA) and indole-3-acetic acid (IAA) were also determined to study their response to nitrogen deficiency. We observed that nitrogen starvation of 2聽days is effective to produce biomass containing 29.92% of lipid (comprising about 75%...
Researchers from Washington University in St. Louis and ORNL are using neutrons to study what happens when cyanobacteria cell samples (pictured) are starved for nitrogen. They are especially interested in how this process affects phycobilisomes, large antenna protein complexes in the cells that harve...
Similar to Xyr1, Scientific Reports | (2023) 13:5057 | https://doi.org/10.1038/s41598-023-32340-x 11 Vol.:(0123456789) www.nature.com/scientificreports/ Gcn4 is also a master transcriptional regulator that mediates the cellular response to amino acid starvation38. It activates ...
Transcriptomic response of the toxic prymnesiophyte Prymnesium parvum (N. Carter) to phosphorus and nitrogen starvation The ichthyotoxic and mixotrophic prymnesiophyte Prymnesium parvum is known to produce dense virtually monospecific blooms in marine coastal, brackish, and ...

This paper has three aims. Firstly, to detail the role of redox-sensitive transcription factors and enzymes, ROS, and reactive nitrogen species (RNS) production and the effect of cellular antioxidants on the activation and performance of macrophages, DCs, neutrophils, T-cells, B-cells, and NK-...
Cellular RNA in Schizosaccharomyces pombe cells drastically decreases in amount during nitrogen starvation. Previously, we found and purified a soluble RNA-degrading enzyme whose activity drastically increased in the cells of S. pombe undergoing nitrogen starvation. The enzyme was a nuclease encoded by ...
Mock-infected A549 cells displayed high p-ERK levels that could be decreased by serum starvation (Supplementary Fig. 11a). However, no neighborhood activation of ERK after HSV-1 infection could be observed, but this may be masked out by the high endogenous p-ERK levels (Supplementary Fig. 11b...
Blocking the import of nutrients essential for cancer cell proliferation represents a therapeutic opportunity, but it is unclear which transporters to target. Here we report a CRISPR interference/activation screening platform to systematically interrogate the contribution of nutrient transporters to support ca...
