Effects of 5-azaC on Iridoid Glycoside Accumulation and DNA Methylation in Rehmannia glutinosa

open access: yesFrontiers in Plant Science, 2022
Iridoid glycoside is the important secondary metabolite and the main active component in Rehmannia glutinosa. However, the mechanisms that underlie the regulation of iridoid glycoside biosynthesis remain poorly understood in R. glutinosa.

Gastrointestinal Issues in CHARGE Syndrome: Prevalence, Patterns, and Constipation‐Related Quality of Life

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Gastrointestinal (GI) symptoms are common in CHARGE syndrome, but their frequency and characteristics remain poorly documented due to the complex nature of CHARGE syndrome. This study aimed to determine the prevalence of GI issues in CHARGE syndrome and their impact on quality of life (QoL).

Multi-omic Analyses of Extensively Decayed Pinus contorta Reveal Expression of a Diverse Array of Lignocellulose-Degrading Enzymes. [PDF]

open access: yes, 2018
Fungi play a key role cycling nutrients in forest ecosystems, but the mechanisms remain uncertain. To clarify the enzymatic processes involved in wood decomposition, the metatranscriptomics and metaproteomics of extensively decayed lodgepole pine were ...

The Expanding Clinical and Genetic Spectrum of Muscle Glycogen Storage Disease 0, (GSD0B)

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Glycogen storage disorders are a group of genetic disorders affecting glucose homeostasis in the body. Muscular glycogen stores are essential for liberating glucose for energy supply during bursts of activity and sustained muscle work. Muscle glycogen storage disease 0 (GSD0B) is associated with biallelic variants in GYS1 causing muscular ...

Stereoselective protecting group free synthesis of d,l-gulose ethyl glycoside via multicomponent enyne cross metathesis—hetero Diels–Alder reaction [PDF]

open access: yes, 2009
An efficient and stereoselective synthesis of d,l-gulose was described. The key step of the synthetic route is represented by a multicomponent enyne cross metathesis—hetero Diels–Alder reaction which allows the formation of the pyran ring from cheap and ...

Large‐Scale Chemoenzymatic Synthesis of a Glycophorin A Tetrasaccharide Motif and Its Analogues

open access: yesAsian Journal of Organic Chemistry, EarlyView.
A large‐scale chemoenzymatic method was developed to synthesize natural and modified analogues of the Glycophorin A tetrasaccharide with either C9 or C5 terminal α‐2,3‐sialic acid variants. Selective α‐2,6‐sialylation of galactosamine was achieved by maintaining acetylation of the galactose during the course of enzymatic reactions. The products can aid

4,6‐O‐Phenylboronic Ester Protection for 1,2‐cis‐α‐Selective Glucosylation

open access: yesAsian Journal of Organic Chemistry, EarlyView.
The 4,6‐O‐phenylboronic ester protection for 1,2‐cis‐α‐selective glucosylation, previously reported by the Crich group, was revisited and the stereodirecting effect of the cyclic protecting group was unveiled. 4,6‐O‐Phenylboronic ester‐protected glucosyl and 2‐azido‐2‐deoxyglucosyl donors exhibited higher α‐selectivity of the glucosylation than the ...
