Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

FEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

FEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

The ubiquitin‐proteasome system and autophagy as guardians of the cellular proteome

FEBS Letters, EarlyView.
This Perspective covers the three principles governing the crosstalk between the ubiquitin‐proteasome system and autophagy in cellular proteostasis: (1) a shared ubiquitin code routing substrates via shuttle factors or autophagy receptors; (2) spatial compartmentalization into phase‐separated degradation hubs and organelle‐specific modules (exemplified

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

FEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Paratuberculosis in small ruminants in the Sudan: prevalence and risk factors

BMC Veterinary Research
Background Paratuberculosis (PTB), caused by Mycobacterium avium subsp. paratuberculosis (MAP), is a contagious and chronic enteric disease of ruminants and many non-ruminants leading to emaciation and death of the animal.

Exporters and the environment [PDF]

Canadian Journal of Economics/Revue canadienne d'économique, 2016
AbstractThis paper documents a relationship between international trade and environmental performance at the plant level. Using a panel of establishment‐level data from 1990–2006, I estimate the relationship between export orientation, import competition and pollution emissions.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Delineating the role of rhizospheric microbes in the amelioration of hexavalent chromium stress in plants

Sustainable Chemistry for the Environment
Hexavalent Chromium is mostly formed from various mining and industrial activities and has severe toxic implications for biotic components. It also hampers soil nutrient profile, thus hindering plant productivity.
