Investigation of the guanine quadruplex resolving activity of the DEAH-box RNA helicase RHAU [PDF]

open access: yes, 2012
Generally depicted as single- or double-stranded molecules, nucleic acids sequences can adopt various forms of stable secondary structures. In particular, guanine-riche sequence of DNA and RNA can form atypical four-stranded helical structures termed G ...

GSLR Drives Lung Adenocarcinoma as a Critical Regulator of Energy Homeostasis Through Creatine Kinase B Activation

open access: yesAdvanced Science, EarlyView.
This study identifies the glucose/glutamine sensitive lncRNA GSLR as a driver of lung adenocarcinoma progression. Nutrient restriction reduces chromatin accessibility at the GSLR locus and blocks CTCF‐mediated transcriptional regulation. GSLR directly interacts with DHX9 and recruits it to the CKB promoter, arresting R‐loop accumulation and promoting ...

Crystal structure of the UvrB dimer: insights into the nature and functioning of the UvrAB damage engagement and UvrB-DNA complexes [PDF]

open access: yes, 2012
UvrB has a central role in the highly conserved UvrABC pathway functioning not only as a damage recognition element but also as an essential component of the lesion tracking machinery.

Developing Metal–Polyphenol Network‐Based Single‐Protein Particle Encapsulation System for Sustained Release of Whey Protein to Mitigate Sarcopenia

open access: yesAdvanced Science, EarlyView.
Sarcopenia has emerged as a major health challenge in the aging population. Developing a sustained‐release system for whey protein may enhance its effectiveness in mitigating sarcopenia. Herein, a novel “single‐protein particle encapsulation” (SPPE) system is developed to protect whey protein and control its release.

Disentangling Heterogeneous Molecular Networks for Multi‐Omics‐Driven Cancer Driver Discovery

open access: yesAdvanced Science, EarlyView.
DRIVE integrates PPI topology and pan‐cancer multi‐omics profiles through dual‐view graph disentanglement, contrastive representation learning, and joint optimization. Across six PPI networks, DRIVE outperforms ten baselines and remains robust to structural and annotation perturbations.

Cellular Mechanisms Enabling Mitochondria Transfer and Transplantation

open access: yesAdvanced Science, EarlyView.
Mitochondrial transfer and transplantation (mitoTT) is examined as a multistep process governed by distinct transfer routes and post‐transfer checkpoints. Mechanisms controlling mitochondrial uptake, network integration, cristae remodeling, mtDNA maintenance, immune sensing, and quality control are highlighted, revealing key biological and ...

A bacterial PriB with weak single-stranded DNA binding activity can stimulate the DNA unwinding activity of its cognate PriA helicase

open access: yesBMC Microbiology, 2011
Background Bacterial DNA replication restart pathways facilitate reinitiation of DNA replication following disruptive encounters of a replisome with DNA damage, thereby allowing complete and faithful duplication of the genome.

Spinal Involvement in Charge Syndrome: Implications for Management

open access: yesAmerican Journal of Medical Genetics Part A, EarlyView.
ABSTRACT CHARGE syndrome (OMIM #214800) is an autosomal dominant disorder caused by mutations in the CHD7 gene in most cases. Although originally defined by the CHARGE acronym (coloboma, heart defects, choanal atresia, growth restriction, genital hypoplasia, and ear anomalies), the recognized phenotype has expanded considerably to include highly ...

Action of CMG with strand-specific DNA blocks supports an internal unwinding mode for the eukaryotic replicative helicase

open access: yeseLife, 2017
Replicative helicases are ring-shaped hexamers that encircle DNA for duplex unwinding. The currently accepted view of hexameric helicase function is by steric exclusion, where the helicase encircles one DNA strand and excludes the other, acting as a ...
