Absolute activity measurements of molybdenum 99 and 4π-γ ion chamber measurements of technetium 99m and of molybdenum 99 with ingrown technetium 99m. [PDF]

open access: yes, 1967
The activity of molybdenum 99 freshly separated from technetium is absolutely measured to ± 1.8 per cent, by 4πв-γ coincidence counting. Internal conversion effects are allowed for and the completeness of the separation is checked from the growth rate of

Mechanical stiffness orchestrates distinct regulation of MRTFs and YAP/TAZ transcriptional cofactors in hepatocytes

open access: yesThe FEBS Journal, EarlyView.
MRTFs and YAP/TAZ proteins, or mechanosensitive transcriptional cofactors (MRTcoF), regulate common genes associated with cellular contractility and immune cell infiltration. Their differential regulation in response to stiffness is linked to changes in hepatocyte's aspect ratio. MRTFB does not undergo nuclear translocation under these conditions. This

Phenotypic characterization of Arabidopsis thaliana mutants that alleviate root growth defects in a vitamin B6 biosynthesis mutant

open access: yesThe FEBS Journal, EarlyView.
Vitamin B6 is a critical molecule for plant metabolism and development. Rsr4‐1, a loss‐of‐function mutant in a vitamin B6 biosynthesis gene, has a distinct short root phenotype. Here we describe five novel suppressor mutants with an rsr4‐1 background that have normalized root growth and distinct phenotypic and molecular characteristics, representing a ...

Physiological media and oxygen levels modulate cancer hallmarks in cultured breast cancer cells

open access: yesThe FEBS Journal, EarlyView.
MCF7 breast cancer cells were cultured in standard conditions (18% O2 and DMEM) and physiological conditions (5% O2 and Plasmax, a medium modeled after the human plasma metabolome). A combined transcriptomic and proteomic approach was used to identify gene expression signatures at the mRNA and protein levels upstream of functional enrichment analyses ...

A chemo‐enzymatic colorimetric cascade for detecting ethylene glycol contamination

open access: yesThe FEBS Journal, EarlyView.
A chemo‐enzymatic cascade is developed for ethylene glycol (EG) detection. EG is oxidized by GoADH with C1‐mediated cofactor recycling to produce glycolaldehyde (GAL). GAL subsequently reacts with purpald to generate a detectable purple chromophore.

CD36‐mediated lipid rewiring in the metabolic adaptation of tumour ecosystems

open access: yesThe FEBS Journal, EarlyView.
Nutrient deprivation drives a lipid‐centric shift in tumour metabolic symbiosis and signalling network. CD36 functions as a bidirectional bridge, transferring fatty acids from stromal donors (adipocytes, CAFs) to the ecosystem tumour‐ and microenvironment‐dependently.

Alternative [2Fe‐2S] donor assemblies in the cytosol: GLRX3 and GLRX3‐BOLA2 converge on NUBP1 maturation

open access: yesThe FEBS Journal, EarlyView.
GLRX3 homodimer and GLRX3‐BOLA2 heterotrimer act as alternative [2Fe‐2S] donor assemblies for NUBP1 maturation. Both systems support formation of [4Fe‐4S] cluster‐bound NUBP1, but display distinct kinetic dependence on the physiological electron donor anamorsin, which accelerates GLRX3‐mediated transfer but does not enhance GLRX3‐BOLA2‐mediated ...

Tankyrase‐2 regulates adipocyte differentiation through AMPK/mTOR signaling

open access: yesThe FEBS Journal, EarlyView.
Tankyrase 2 (TNKS2), a PARP family member, underpins adipocyte differentiation. TNKS2 controls LKB1 protein level, and consequently, the activity of the mTOR/AMPK system and adipocyte differentiation through a layered process. Pharmacological inhibition of TNKS2 leaves other PARPs and DNA repair active and therefore represents a novel target in ...

Arabidopsis inositol polyphosphate kinase activities regulate COP9 deneddylation functions in phosphate homeostasis

open access: yesJournal of Integrative Plant Biology, EarlyView.
Plant phosphate (Pi) homeostasis relies on coordinated activities of the inositol polyphosphate kinases IPK1 and ITPK1, which balance localized InsP7 biosynthesis to control COP9 signalosome (CSN)‐dependent deneddylation of cullin 1 (CUL1). Perturbation of this equilibrium affects the stability of SPX4, a key negative regulator of phosphate starvation ...

SlMED25‐SlPHR3‐SlSPX2 module fine‐tunes SlPHR3‐mediated transcriptional activation of phosphate starvation response in tomato

open access: yesJournal of Integrative Plant Biology, EarlyView.
The Mediator subunit SlMED25 and the co‐repressor SlSPX2 competitively bind the N‐terminal domain of the phosphate starvation response transcription factor SlPHR3 in tomato to form a sensitive molecular switch, which dynamically modulates phosphate starvation responses and maintains phosphate homeostasis, offering valuable targets for breeding low ...
