Inactivation of a heterocyst-specific invertase indicates a principal role of sucrose catabolism in heterocysts of Anabaena sp.
(American Society for Microbiology, 2010)
Anabaena sp. strain PCC 7120 is a filamentous cyanobacterium that carries out N2 fixation in specialized cells called heterocysts, which exchange nutrients and regulators with the filament's vegetative cells that perform ...

Cytochrome c lysine acetylation regulates cellular respiration and cell death in ischemic skeletal muscle
(Springer Nature, 2023)
Skeletal muscle is more resilient to ischemia-reperfusion injury than other organs. Tissue specific post-translational modifications of cytochrome c (Cytc) are involved in ischemia-reperfusion injury by regulating mitochondrial ...

The Multitasker Protein: A Look at the Multiple Capabilities of NUMB
(Multidisciplinary Digital Publishing Institute (MDPI), 2023)
NUMB, a plasma membrane-associated protein originally described in Drosophila, is involved in determining cell function and fate during early stages of development. It is secreted asymmetrically in dividing cells, with one ...

Editorial: Biology of stress granules in plants
(Frontiers Media S.A., 2022-06-09)
Eukaryotic cells have developed sophisticated mechanisms to survive under ever-changing environments which include compartmentalization of translationally arrested mRNA molecules and proteins into a type of membraneless ...

Photorespiration: regulation and new insights on the potential role of persulfidation
(Oxford University Press, 2023-07-24)
Photorespiration has been considered a 'futile' cycle in C3 plants, necessary to detoxify and recycle the metabolites generated by the oxygenating activity of Rubisco. However, several reports indicate that this metabolic ...

Programmed cell death (PCD): an essential process of cereal seed development and germination
(Frontiers media, 2014)
The life cycle of cereal seeds can be divided into two phases, development and germination, separated by a quiescent period. Seed development and germination require the growth and differentiation of new tissues, but ...

Low nitrogen status affects isoflavonoid production and flavonol decoration in Lotus corniculatus
(Elsevier, 2024-03)
Nitrogen availability is key factor for plant metabolism and has a strong impact on the biosynthesis of secondary plant metabolites. A number of these metabolites are involved in the response to stress. In this paper, we ...

Nicotinamide N-methyltransferase (NNMT) regulates the glucocorticoid signaling pathway during the early phase of adipogenesis
(Springer Nature, 2023-05-22)
Obesity is associated with adipose tissue dysfunction through the differentiation and expansion of pre-adipocytes to adipocytes (hyperplasia) and/or increases in size of pre-existing adipocytes (hypertrophy). A cascade of ...

Characterization of the response to zinc deficiency in the cyanobacterium Anabaena sp. strain PCC 7120
(American Society for Microbiology, 2012)
Zur regulators control zinc homeostasis by repressing target genes under zinc-sufficient conditions in a wide variety of bacteria. This paper describes how part of a survey of duplicated genes led to the identification of ...

Ectopic overexpression of the cell wall invertase gene CIN1 leads to dehydration avoidance in tomato
(Oxford University Press, 2015)
Drought stress conditions modify source–sink relations, thereby influencing plant growth, adaptive responses, and consequently crop yield. Invertases are key metabolic enzymes regulating sink activity through the hydrolytic ...
