Characterization of meiotic crossovers and gene conversion by whole-genome sequencing in Saccharomyces cerevisiae

BMC Genomics, 2009
Background Meiotic recombination alters frequency and distribution of genetic variation, impacting genetics and evolution. In the budding yeast, DNA double strand breaks (DSBs) and D loops form either crossovers (COs) or non-crossovers (NCOs), which ...

Pathogenicity of Mediator Complex Subunit 27 (MED27) in a Neurodevelopmental Disorder with Cerebellar Atrophy

Advanced Science, EarlyView.
MED27 is one of the 26 subunits in the human Mediator complex (MED). Neurodevelopmental disorder‐causing MED27 genetic variants induce instability of MED, leading to disrupted DNA occupancy, altered chromatin interaction, and subsequent transcriptional dysregulation of critical downstream genes, including master regulatory transcription factors ...

TSHR‐Targeting Nucleic Acid Aptamer Treats Graves' Ophthalmopathy via Novel Allosteric Inhibition

Advanced Science, EarlyView.
This study presents YC3, a novel inhibitory TSHR‐targeting aptamer, as a promising therapeutic for Graves' ophthalmopathy (GO). YC3 suppresses pathological phenotypes in human orbital fibroblasts and improves outcomes in GO mice by binding to a previously unidentified allosteric site on TSHR, demonstrating the potential of aptamers in advancing ...

Identifying Tipping Points during Healthy Brain Aging through Single‐Nucleus Transcriptomic Analysis

Advanced Science, EarlyView.
This study applies single‐nucleus transcriptomics and systems dynamics to uncover nonlinear aging patterns in healthy human brains. By introducing dynamic network biomarker theory, the authors identify a critical tipping point at ages 56–60 during aging, and highlight glial instability as a key mediator.

tRNA‐Derived Fragment tRF‐22 Promotes Immunosuppression by Inhibiting HnRNPAB Ubiquitination in Esophageal Squamous Cell Carcinoma

Advanced Science, EarlyView.
tRF‐22 fosters an immunosuppressive and pro‐oncogenic tumor microenvironment in ESCC by stabilizing hnRNPAB against TRIM25‐mediated ubiquitination and enhancing TGFβ2 expression, which increases PMN‐MDSCs infiltration and suppresses CD8+ T cells. Targeting tRF‐22 or blocking TGFβ signalling improves anti‐PD1 response, offering a promising therapeutic ...

Highly Ordered DNA Framework Interface Enables Efficient Enzymatic Oligonucleotide Synthesis

Advanced Science, EarlyView.
Tetrahedral DNA nanostructures (TDN) ‐based nanoscopic interface provides ordered upright orientation and optimal spacing for initiator primers, enhancing enzyme accessibility in interfacial enzymatic oligonucleotide synthesis (EOS). Notably, efficient TDN‐based EOS is employed for DNA information storage by synthesizing a 60‐nucletide DNA fragment ...

Super‐Resolution Compatible DNA Labeling Technique Reveals Chromatin Mobility and Organization Changes During Differentiation

Advanced Science, EarlyView.
A novel chromatin‐labeling probe is developed to investigate chromatin mobility during differentiation. The silicon rhodamine–conjugated dCTP is efficiently delivered into iPSCs and NSCs using a synthetic transporter. Super‐resolution microscopy and single‐particle tracking show decreased chromatin mobility during differentiation.
