Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

open access: yesFEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Effect of evaporative fractionation on the distribution and composition of diamondoids in crude oils: a case study of crude oils from Yangtake structure, Kuqa Depression, Tarim Basim

open access: yesShiyou shiyan dizhi, 2022
Two sets of crude oil samples from the Yangtake structure in the Kuqa Depression of Tarim Basin were analyzed with the aid of GC and GC-MS to evaluate the effect of evaporative fractionation on the distribution and composition of diamondoid hydrocarbon ...

Nitrogen isotopic ratios in Barnard 1: a consistent study of the N2H+, NH3, CN, HCN and HNC isotopologues

open access: yes, 2013
The 15N isotopologue abundance ratio measured today in different bodies of the solar system is thought to be connected to 15N-fractionation effects that would have occured in the protosolar nebula.

The newfound relationship between extrachromosomal DNAs and excised signal circles

open access: yesFEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Advances in Research on Uranium Isotope Fraction in Nature and Prospects

open access: yesHe huaxue yu fangshe huaxue, 2022
Uranium is the heaviest naturally occurring radioactive element in nature, and it is widely distributed in the earth’s crust. With the improvement of the technical accuracy of mass spectrometry to measure uranium isotope ratios, it is gradually ...

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

open access: yesFEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

The Effect of the Time Interval Between Radiation and Hyperthermia on Clinical Outcome in 400 Locally Advanced Cervical Carcinoma Patients

open access: yesFrontiers in Oncology, 2019
Background: Addition of deep hyperthermia to radiotherapy results in improved local control (LC) and overall survival compared to radiotherapy alone in cervical carcinoma patients.

Nitrogen Isotopic Fractionation in Interstellar Ammonia [PDF]

open access: yes, 2010
Using the Green Bank Telescope (GBT), we have obtained accurate measurements of the $^{14}$N/$^{15}$N isotopic ratio in ammonia in two nearby cold, dense molecular clouds, Barnard~1 and NGC 1333. The $^{14}$N/$^{15}$N ratio in Barnard~1, $334 \pm 50$ (3$\
