Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization

Molecular Oncology, EarlyView.
In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.

Sudden anaerobization in Amphibacillus xylanus increases intracellular labile ferrous iron and inhibits cell growth

FEBS Open Bio, EarlyView.
Abruptly changing from aerobic to anaerobic conditions (sudden anaerobization) induced growth inhibition and a significant increase in intracellular labile ferrous iron in the aerotolerant anaerobe Amphibacillus xylanus. We found that free flavins mediate efficient electron transfer from NADH to ferric iron under anaerobic conditions, suggesting that ...

Dose‐dependent hepatotoxicity of hydrogen peroxide in HepG2 cells and its modulation by CYP450 induction

FEBS Open Bio, EarlyView.
NMR metabolomics revealed concentration‐dependent metabolic perturbations in HepG2 cells exposed to H2O2. Rifampicin pretreatment enhanced metabolic competence, attenuated toxin‐induced alterations and produced metabolite profiles more consistent with human liver physiology, supporting the use of CYP450‐induced HepG2 models for improved in vitro ...

More Than a Methanotroph: A Broader Substrate Spectrum for Methylacidiphilum fumariolicum SolV

Frontiers in Microbiology, 2020
Volcanic areas emit a number of gases including methane and other short chain alkanes, that may serve as energy source for the prevailing microorganisms.

SOLATION AND IDENTIFICATION OF SOME LOCAL ISOLATES OF Bradyrhizobium SP. (LUPINUS) USING SEROLOGICAL AND ANTIBIOTIC RESISTANCE MARKERS AND THEIR SYMBIOTIC PERFORMANCE UNDER DIFFERENT LEVELS OF N-FERTILIZATION [PDF]

Journal of Agricultural Chemistry and Biotechnology, 2004
From eight isolates of Bradyrhizobium sp. (Lup < /em>inus) (were selected from many isolates on the basis of their N2-fixation efficient), four different groups were obtained and identified according to their sensitivity and resistance to ...

Avidin is evolutionarily conserved in fish but dispensable for development and resistance against Streptococcus agalactiae in zebrafish

FEBS Open Bio, EarlyView.
The presence of biotin‐binding avidin proteins in fish and their biological significance are poorly characterized. We cataloged fish avidins and demonstrate that they are widely present and evolutionarily conserved. We created avd knockout zebrafish and show that zebavidin is dispensable for development and that resistance of avd knockout embryos in ...

THE POTENTIAL USE OF AZOLLA AS NITROGEN SOURCE IN RICE PRODUCTION [PDF]

Journal of Soil Sciences and Agricultural Engineering, 2002
A field experiment was conducted at EL-Kalubia governorate at the season (June - October 2001) to study the potential of Azolla application as bio-nitrogen source in comparison with the mineral nitrogen fertilizer as urea as well as their effect on ...
