Nutrient/TOR signaling controls adipose mitochondrial transcription factor A (TFAM) to regulate organismal growth in Drosophila

FEBS Letters, EarlyView.
Animals must match their growth rate to available nutrients. We show that in Drosophila larvae, the nutrient‐sensing TOR kinase controls growth by regulating levels of TFAM, a key regulator of mitochondrial function, in the adipose tissue. When nutrients are abundant, high TOR activity suppresses TFAM, lowering mitochondrial bioenergetic activity and ...

Unfolding phenolics biosynthetic plasticity of Artemisia alba Turra through plant tissue culture techniques

Artemisia alba Turra is an essential oil bearing plant, with Euro-Mediterranean and Southeastern European distribution. One of the distinctive characteristics of its essential oil is the variability of its terpenoid profile due to environmental, genetic ...

The Growth Response of Several Potato Genotypes (<i>Solanum tuberosum</i> L.) to Induced Water Stress Using Sorbitol and Polyethylene Glycol

Notulae Scientia Biologicae, 2016
The current paper aimed to study the in vitro response of potato genotypes to water stress induced by adding sorbitol and polyethylene glycol in the culture medium. The biological material analysed in the experiment was represented by a Romanian line ‘LP

Liver organoids: modelling complexity in homeostasis and disease

FEBS Letters, EarlyView.
Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

The microbiome in human skin aging

FEBS Letters, EarlyView.
Age‐related skin changes encompass the well‐known visible phenotypic alterations, together with microbiome dysbiosis and a series of molecular aging hallmarks. These hallmarks characterize not only a fully stablished aged phenotype but also the skin aging process itself.

Plant Cell Tissue Organ Cult.

, 1999
Liquid-cultivated compact callus aggregates (CCA) of Rhodiola sachalinensis were initiated from the explant of stems. Microscopic analysis showed that CCA displayed some level of cellular/tissue differentiation, which was perhaps responsible for the ...

Translophagy—A potential link between autophagy impairment and translational errors

FEBS Letters, EarlyView.
Neurodegenerative diseases are characterised by the accumulation of abnormal proteins and protein aggregates, but their origin often remains unknown. We propose that selective autophagy removes damaged protein‐making machinery, preventing errors during protein synthesis.

Impact of Exogenous Cytokinin and Auxin on In Vitro Culture of Pineapple (Ananas comosus) (L) var Sweet Cayenne Under Aseptic Conditions

Advances in Agriculture
An efficient micropropagation technique for pineapple utilizes shoot crowns as an explant. Traditional propagation methods are slow and insufficient for large-scale production due to the small number of suckers naturally produced by the plant. This study
