The Impact of the Growth Regulators and Cultivation Conditions of Temporary Immersion Systems (TISs) on the Morphological Characteristics of Potato Explants and Microtubers

Agronomy
Potatoes (Solanum tuberosum L.) constitute one of the most economically important annual crops. In terms of tissue culture, potato microtubers (MTs) have a number of advantages over conventional plants.

Loss of AMBRA1 activates MAPK and angiogenesis signaling pathways in melanoma cells

FEBS Open Bio, EarlyView.
Loss of AMBRA1 in melanoma cells activates multiple oncogenic pathways associated with tumor progression. Transcriptomic and protein network analyses revealed that AMBRA1 depletion enhances MAPK/ERK signaling, angiogenesis, TGF‐β/EMT signaling, and Wnt/axon guidance pathways.

Antioxidant and nutrient content of micropropagated Costus pictus inoculated with beneficial soil microorganisms

, 2010
A suitable medium for the in-​vitro culture of Costus pictus D.Don, was standardized. Aerial rhizomes were used as explants. Different combinations of NAA and BAP and other supplements using MS medium were tried.

From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

FEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

Effect of terahertz irradiation on DNA damage repair in living cells

FEBS Open Bio, EarlyView.
We investigated the effect of terahertz (THz) wave irradiation on DNA double‐strand break (DSB) repair in living cells. We found that THz irradiation enhanced DSB repair at specific frequencies, whereas heat treatment inhibited it, indicating that this effect is nonthermal and frequency‐specific.

Responses of Vallisneria natans to reduced light availability and nutrient enrichment

, 2008
The effects of light and nutrient availability, 3 (light) x 3 (nutrient), on growth and N, P and C concentrations of Vallisneria natans were investigated in a microcosm experiment. Growth of V. natans decreased with increased light limitation. Inhibition

A new flow chip in combination with multiphoton microscopy as a protocol for longitudinal 3D imaging of tissue calcification under shear stress

FEBS Open Bio, EarlyView.
Miniaturized flow chip platform enabling continuous perfusion and longitudinal multiphoton 3D imaging of vascular smooth muscle cell constructs under physiological flow. Brightfield imaging guides region selection, while CellTracker Green and mRuby‐labeled fetuin‐A visualize cells and mineral deposition, respectively. Magnesium supplementation markedly
