Differential roles of C-3 and C-6 phosphate monoesters in affecting potato starch properties

Grain & Oil Science and Technology 2024年第2期7卷 79-86页

作者： Li Ding andreas Blennow Yuyue Zhong Department of Plant and Environmental Sciences Faculty of ScienceUniversity of CopenhagenDenmark Department of Sustainable and Bio-inspired Materials Max-Planck Institute of Colloids and InterfacesPotsdamGermany

The effects of starch phosphate monoester content(SPC),namely C-3(C3P)and C-6 phosphate monoesters(C6P),on the starch properties were investigated using four potato starches with varied SPC/C3P/C6P and two nonphosphorylated maize starches with a similar range of amylose content(AC)as *** starch property results showed that a higher SPC is associated with lower turbidity,storage and loss modulus after storage,and water solubility,but higher swelling power(SP)and pasting *** findings suggested that SPC inhibited molecular rearrangement during storage and starch leaching during heating,and enhanced swelling and viscosities due to increased hydration and water uptake caused by the repulsion effect of phosphate groups and a less ordered crystalline *** SPC also resulted in lower resistant starch(RS)content in a native granular state but higher RS after *** correlations further indicated that SPC/C3P/C6P were positively correlated with peak(r^(2)=0.925,0.873 and 0.930,respectively),trough(r^(2)=0.994,0.968 and 0.988,respectively),and final viscosities(r^(2)=0.981,0.968 and 0.971,respectively).Notably,SPC,mainly C3P,exhibited a significantly positive correlation with SP(r^(2)=0.859)and setback viscosity(r^(2)=0.867),whereas SPC,mainly C6P,showed a weak positive correlation with RS after retrogradation(r^(2)=0.746).However,SPC had no significant correlations with water solubility,turbidity and rheology properties,which were more correlated with *** findings are helpful for the food industry to select potato starches with desired properties based on their contents of SPC,C3P,or C6P.

Targeted nanopore sequencing for the identification of novel PRMT1 circRNAs unveils a diverse transcriptional profile of this gene in breast cancer cells

引用

Genes & Diseases 2024年第2期11卷 589-592页

作者： Maria Papatsirou andreas Scorilas Diamantis C.Sideris Christos K.Kontos Department of Biochemistry and Molecular Biology National and Kapodistrian University of AthensPanepistimiopolisAthens GR 15701Greece

Long-read sequencing with nanopore technology has been widely utilized for the identification of the full-length sequence of RNA molecules."It is especially suitable for the identification of circular RNAs(circRNAs),which are regulatory molecules that are regarded as promising non-invasive biomarkers for various human malignancies,including breast cancer.2 The impact of circRNAs derived from the protein arginine methyltransferase 1(PRMT1)gene has not been clarified yet,even though the effect of PRMT1-mediated methylation on breast cancer cell characteristics has been well established.
