Autophagy processes are dependent on EGF receptor signaling [PDF]

, 2018
Autophagy is a not well-understood conserved mechanism activated during nutritional deprivation in order to maintain cellular homeostasis. In the present study, we investigated the correlations between autophagy, apoptosis and the MAPK pathways in ...

Lipid Catabolism in Starved Yak Is Inhibited by Intravenous Infusion of β-Hydroxybutyrate

Animals, 2020
Lipid is the chief energy source for starved animals. β-hydroxybutyrate (BHBA) is the main ketone body produced by lipid decomposition. In Chinese hamster ovary (CHO) cell experiment, it was found that BHBA could be used not only as an energy ...

The response of diatom central carbon metabolism to nitrogen starvation is different from that of green algae and higher plants [PDF]

, 2011
The availability of nitrogen varies greatly in the ocean and limits primary productivity over large areas. Diatoms, a group of phytoplankton that are responsible for about 20% of global carbon fixation, respond rapidly to influxes of nitrate and are ...

PNAS plus: plasmodium falciparum responds to amino acid starvation by entering into a hibernatory state [PDF]

, 2012
The human malaria parasite Plasmodium falciparum is auxotrophic for most amino acids. Its amino acid needs are met largely through the degradation of host erythrocyte hemoglobin; however the parasite must acquire isoleucine exogenously, because this ...

Proteomic Study of Mitochondria-Associated Endoplasmic Reticulum in Saccharomyces cerevisiae under Different Nutritional Conditions

Zhipu Xuebao
The mitochondrial-associated endoplasmic reticulum membrane (MAM) is an essential component of eukaryotic cells. It is involved in many critical cellular functions, such as bioenergetics, mitophagy, apoptosis, and calcium signaling, regulating cellular ...

The Metabolic Regulation of Amino Acid Synthesis Counteracts Reactive Nitrogen Stress via Aspergillus nidulans Cross-Pathway Control

Journal of Fungi
Nitric oxide (NO) is a natural reactive nitrogen species (RNS) that alters proteins, DNA, and lipids and damages biological activities. Although microorganisms respond to and detoxify NO, the regulation of the cellular metabolic mechanisms that cause ...

Starvation Stress Causes Body Color Change and Pigment Degradation in Acyrthosiphon pisum

Frontiers in Physiology, 2019
The pea aphid, Acyrthosiphon pisum (Harris), shows body color shifting from red to pale under starvation in laboratory conditions. These body color changes reflect aphid’s adaptation to environmental stress. To understand the color-shifting patterns, the
