Coordinated expression of sulfate uptake and components of the sulfate assimilatory pathway in maize

, 2004
A high-affinity-type sulfate transporter (Group 1: ZmST1;1, Accession No. AF355602) has been cloned from maize seedlings by RT-PCR. Tissue and cell specific localisation of this sulfate transporter has been determined along the developmental gradient of ...

Divergent Synthesis of Lamellarin α 13-Sulfate, 20-Sulfate, and 13,20-Disulfate [PDF]

, 2010
A divergent synthesis of three sulfate derivatives of lamellarin α, namely, lamellarin α 13-sulfate (2), 20-sulfate (1), and 13,20-disulfate (4) has been achieved via a common intermediate (6) in which 13-OH and 20-OH of the lamellarin core are ...

Loss of IGF‐1R impairs DNA‐PKcs recruitment to chromatin leading to defective end‐joining

Molecular Oncology, EarlyView.
IGF‐1R promotes radioresistance by facilitating DNA‐PKcs recruitment to chromatin, enabling non‐homologous end‐joining (NHEJ) repair of double‐strand breaks. Inhibition or loss of IGF‐1R disrupts this recruitment to damage sites, driving compensatory reliance on microhomology‐mediated end‐joining (MMEJ) repair.

USP29‐regulated noncanonical stabilization of the hypoxia‐inducible factor‐α in aggressive prostate cancer

Molecular Oncology, EarlyView.
We identify USP29 as the only DUB mirroring CA9 expression, a marker of hypoxia and HIF pathway activation associated with PCA aggressiveness. USP29 stabilizes HIF‐1α and HIF‐2α via a noncanonical mechanism that is independent of PHD/pVHL activity yet relies on proteasomal regulation, establishing USP29 as a previously unrecognized regulator of hypoxic

Association between intravenous magnesium sulfate and mortality in patients with sepsis-associated liver injury: a retrospective cohort study

Frontiers in Medicine
BackgroundSepsis-associated liver injury (SALI) is a significant risk factor for mortality in patients with sepsis. Magnesium, as an essential electrolyte, has a correlation with adverse outcomes in critical illness when deficient, yet the therapeutic ...

Crystal Structures of Two 1,4-Diamino-1,2,4-triazolium Salts

Crystals, 2016
Bis(1,4-diamino-1,2,4-triazolium) sulfate (1) was obtained from the corresponding chloride by ion metathesis using Ag2SO4. Further metathesis with barium 5,5′-azotetrazolate yielded bis(1,4-diamino-1,2,4-triazolium) 5,5′-azotetrazolate (2). Numerous NH···

Loss of proton‐sensing TDAG8 increases tumor progression in mouse models of colon cancer

Molecular Oncology, EarlyView.
Loss of the pH‐sensing receptor TDAG8 accelerates colorectal cancer progression in mice. Animals lacking TDAG8 expression had increased tumor growth, DNA damage, and recruitment of tumor‐associated immune cells, including macrophages, neutrophils, and monocytes.

Liberation of sulfate from sulfate esters by soils [PDF]

Applied and Environmental Microbiology, 1976
When incubated with acid, alkaline, and neutral soils, a variety of synthetic sulfate esters representing the various classes of these compounds was hydrolyzed by enzymes, probably of microbial origin. The appearance of sulfate in the soil water occurred immediately after introduction into the soils with some esters, whereas with others it occurred ...
