Molecular Plant 2024年第6期17卷 842-844页

作者： Sunita Pathak lucia C.Strader Department of Biology Duke UniversityDurhamNCUSA

Plants are exposed to a range of daily and seasonal temperatures and thus are required to regulate their cellular processes under fluctuating temperature *** various temperature-responsive genes,GLYCINE-RICH RNA BINDING PRoTEIN7(GRP7)encodes a glycine-rich RNA-binding protein that provides freezing tolerance to plants(Carpenter et al.,1994;Kim et al.,2008)by acting as an RNA chaperone(Kwak et al.,2011).

Advancing pediatric exercise research:A focus on immunomics and cutting-edge technologies

*** importance of immunomics in pediatric exercise research The profound effect that"acute"or"regular"exercise(i.e.,a single exercise session or repeated sessions over time,respectively)exerts on the immune system has been widely recognized.1 Acute exercise is largely"immuno-enhancing"(e.g.,it may even improve vaccine responses in"at-risk"patients),whereas regular exercise reduces the risk of chronic conditions(not only obesity,diabetes,or cardiovascular diseases,but also several types of cancer)partly due to its anti-inflammatory effects.

Strong evidence supports the benefits of regular physical activity/exercise for the prevention and management of numerous non-communicable diseases.^(1,2)However,despite important advances(particularly the implementation of complex“omics”approaches),the underlying molecular mechanisms remain to be clearly *** the past decade,the role of exerkines—a myriad of signaling moieties(e.g.,mainly cytokines but also other small peptides,peptides,nucleic acids,lipids,or metabolites,among others)released by muscles(myokines)and other tissues in response to exercise that induces endocrine(at the multisystem level),paracrine,or autocrine effects—has gained attention.^(3,4)Indeed it has been proposed that some of the salutary effects of regular exercise(i.e.,repeated sessions of acute exercise)might be due,at least partly,to the progressive accumulation of frequent,acute episodes of exerkine release.^(5)

Gastroesophageal reflux disease(GERD)is defined by recurrent and troublesome heartburn and effortless regurgitation or by the specific complications of this condition—that is,esophagitis,esophageal peptic strictures,and Barrett esophagus.1Although GERD is caused by gastric contents'reaching the esophagus,gastric juices can also reach other anatomical locations(pharynx,mouth,larynx,and airways),leading to(or worsening)extra-esophageal conditions(notably asthma)or symptoms(e.g.,wheezing,cough).1 Together with obesity,GERD is the main risk factor for gastroesophageal malignancies.
