At least 18 different integral plasma membrane proteins undergo starvation-induced endocytosis including different amino acid permeases, sugar transporters and the G-protein coupled receptor, Ste2.
Autophagy is in principle a cytoplasmic process that does not require a nuclear-localized transcriptional response for short-term activity, as demonstrated by the ability of cytoplasts (i.e., enucleated cells) to undergo starvation-induced autophagy (Morselli et al., 2011).
The Wikipedia article (for the painting, not the actual ship) succinctly describes the 147 passengers and crew set adrift as undergoing "starvation, dehydration, cannibalism and madness" — not necessarily in that order, or one at a time.
Phosphorylation of S174 can be detected in cells growing in nutrient-rich conditions and in cells undergoing starvation, which implies that phosphorylation of S174 is not regulated by nitrogen starvation (Fig. 3D).
Our study utilizes an evolutionary agent based model (EABM) to simulate the effects of hypergravity on specific cellular cultures undergoing starvation.
Extractions of three individuals from each resulting phenotype after having undergone starvation or pesticide treatment were performed and two replicates of each extraction were used for qPCR.
Fungus grown on borosilicate 3 mm solid glass beads (Aldrich, Milwaukee, WI) in 1% glucose for 34 hours was used as a control for comparison of secretomes. A. nidulans cultured in 1% glucose for 34 hrs utilized only 1/4th of the initial glucose and thus should not be undergoing starvation.
We found that, whereas mitochondria in control cells elongated or hyperfused after starvation with HBSS, mitochondria in Trak1-depleted cells were incapable of undergoing starvation-induced mitochondrial elongation, and they remained fragmented (Fig. 10A and 10B).
Packets that consist of a low-priority level may undergo resource starvation when the requested requirements, based on the overall bandwidth, are unsatisfied [21, 28].
C. crescentus is able to considerably increase stalk length when cells undergo phosphate starvation [16], thereby optimizing nutrient exchange [38].
Moreover, C. albicans has been shown to undergo carbon starvation and glucose deprivation after internalization by macrophages [ 47].
