A pyrophosphatase that regulates lipid precursors of N -glycosylation

Written by Posted on Less than 0 min read

The oligosaccharide used for protein N-glycosylation in the ER is built as a glycolipid. A recent study by Li, Suzuki, and colleagues (https://doi.org/10.1083/jcb.202501239) identifies a long-sought enzyme that hydrolyzes this lipid as part of a possible homeostatic/quality control mechanism.

Zibotentan/Dapagliflozin Combination Demonstrated Significant Albuminuria Reduction in Patients with Chronic Kidney Disease and Proteinuria in ZENITH-CKD Phase IIb Trial

November 3, 2023 — Combination of zibotentan with dapagliflozin showed statistically significant and clinically meaningful reductions in urinary albumin-to-creatinine ratio (UACR), used to assess albuminuria, at 12 weeks compared with dapagliflozin alone. After 12 weeks of treatment, the Phase IIb ZENITH-CKD trial showed that the UACR difference of zibotentan/dapagliflozin versus dapagliflozin alone (n=177) was –33.7% […]

The EU should allow gene editing to make organic farming more sustainable, researchers say

To achieve the European Green Deal’s goal of 25% organic agriculture by 2030, researchers argue that new genomic techniques (NGTs) should be allowed without pre-market authorization in organic as well as conventional food production. NGTs — also known as gene editing- — are classified under the umbrella of GMOs, but they involve more subtle genetic […]

Scientists shocked as birds soaked in “forever chemicals” still thrive

A new study published in Environmental Toxicology and Chemistry by Oxford University Press reports that many tree swallow populations across the United States are living in areas with high levels of exposure to “forever” chemicals. Surprisingly, the researchers found that this exposure did not appear to harm the birds’ reproductive health. Per- and polyfluoroalkyl substances, […]

A cholesterol secret inside ticks may halt Lyme disease spread

Washington State University researchers have discovered how the bacteria that cause anaplasmosis and Lyme disease hijack cellular processes in ticks to ensure their survival and spread to new hosts, including humans. Based in the College of Veterinary Medicine, the team found that the bacteria can manipulate a protein known as ATF6, which helps cells detect […]

System to auto-detect new variants will inform better response to future infectious disease outbreaks

Researchers have come up with a new way to identify more infectious variants of viruses or bacteria that start spreading in humans — including those causing flu, COVID, whooping cough and tuberculosis. The new approach uses samples from infected humans to allow real-time monitoring of pathogens circulating in human populations, and enable vaccine-evading bugs to […]

McGill University researchers, in collaboration with Mexican scientists, have discovered two previously unknown species of crocodiles, one living on the island of Cozumel and the other on the atoll of Banco Chinchorro, both off the Yucatán Peninsula. The findings challenge long-held assumptions about the American crocodile (Crocodylus acutus) and highlight the urgent need for conservation […]

Myths about intermittent fasting, debunked

In a new article, researchers at the University of Illinois Chicago debunk four common myths about the safety of intermittent fasting. Intermittent fasting has become an increasingly popular way to lose weight without counting calories. And a large body of research has shown it’s safe. Still, several myths about fasting have gained traction among clinicians, […]

Crushing vs. Slashing: New skull scans reveal how giant dinosaurs killed

A new analysis of the bite strength of 18 species of carnivorous dinosaurs shows that while the Tyrannasaurus rex skull was optimized for quick, strong bites like a crocodile, other giant, predatory dinosaurs that walked on two legs — including spinosaurs and allosaurs — had much weaker bites and instead specialized in slashing and ripping […]

Innovative field experiments shed light on biological clocks in nature

Africa’s pangolin crisis: The delicacy that’s driving a species to the brink

The vast majority of pangolin hunting in African forest landscapes is done for meat consumed by people in the region, rather than for scales shipped to East Asia, a new study led by the University of Cambridge suggests. Pangolins are the most heavily trafficked wild mammal in the world. A solitary, insect-eating animal about the […]

An inexpensive fix for California’s struggling wildflowers

California’s native wildflowers are being smothered by layers of dead, invasive grasses. A new UC Riverside study shows that simply raking these layers can boost biodiversity and reduce fire danger. The study, published this week in Restoration Ecology, tested whether removing thatch — dead leaves and debris — could allow native seeds to germinate and […]

Non-cell autonomous regulation of cell–cell signaling and differentiation by mitochondrial ROS

Mitochondrial reactive oxygen species (ROS) function intrinsically within cells to induce cell damage, regulate transcription, and cause genome instability. However, we know little about how mitochondrial ROS production non-cell autonomously impacts cell–cell signaling. Here, we show that mitochondrial dysfunction inhibits the plasma membrane localization of cell surface receptors that drive cell–cell communication during oogenesis. Within […]

Directed stochasticity: Building biomolecular condensates in the right place

Controlling biomolecular condensate formation within the nucleus is critical for genome function. In this issue, Xu et al. (https://doi.org/10.1083/jcb.202401036) report that KPNA3 promotes histone locus body formation and expression of replication-dependent histone genes by both importing NPAT into the nucleus and preventing NPAT condensation from improperly occurring in the cytoplasm.

LLP1 is a pyrophosphatase involved in homeostasis/quality control of dolichol-linked oligosaccharide

Dolichol-linked oligosaccharide (DLO) is the precursor for asparagine (N)-linked protein glycosylation. DLO synthesis can be impaired by genetic and environmental factors, leading to the accumulation of various immature DLO intermediates that are subsequently cleaved into phosphorylated oligosaccharides (POSs). Despite the fact that its activity has been known since the 1970s, the identity of the enzyme […]
