Single Cell and Spatial Transcriptomics Define a Proinflammatory and Profibrotic Niche After Kidney Injury

open access: yesAdvanced Science, EarlyView.
By integrating single‐cell RNA sequencing and spatial transcriptomics, tenascin C (TNC) is unveiled as a central organizer of the proinflammatory and profibrotic niche in kidney fibrosis. TNC promotes macrophage activation through TLR4/NF‐κB signaling, leading to renal inflammation and fibrosis.

Chloroplast Fibrillin‐Mediated α‐Tocopherol Biosynthesis Impaired by a Virus to Enhance Infection and to Improve Drought Tolerance

open access: yesAdvanced Science, EarlyView.
ToCV‐encoded p22 targets chloroplast plastoglobules (PGs) via directly binding PG structural protein FBN1.1, reducing the size of PG and inhibiting α‐tocopherol biosynthesis via competing with tocopherol cyclase (VTE1). Consequently, the elevated chloroplast ROS not only creates a suitable cellular environment for efficient ToCV infection but also ...

Antibiotic resistance evolved via inactivation of a ribosomal RNA methylating enzyme. [PDF]

open access: yes, 2016
Modifications of the bacterial ribosome regulate the function of the ribosome and modulate its susceptibility to antibiotics. By modifying a highly conserved adenosine A2503 in 23S rRNA, methylating enzyme Cfr confers resistance to a range of ribosome ...

A Patient‐Derived Organoid Biobank of Adamantinomatous Craniopharyngioma as a Platform for Drug Discovery

open access: yesAdvanced Science, EarlyView.
This study successfully establishes adamantinomatous craniopharyngioma (ACP) patient‐derived organoids (PDOs) that preserve the histopathological and genetic features of the original tumors. Through drug sensitivity assays and subsequent mechanistic analyses, the study demonstrates that Ceritinib exerts its inhibitory effects on ACP PDO growth by ...

Sabotaged Integral HSC Heterogeneity Underlies Essential Thrombocythemia Development

open access: yesAdvanced Science, EarlyView.
Single‐cell RNA sequencing (scRNA‐seq) maps how distinct driver mutations remodel hematopoietic stem cell (HSC) programs across essential thrombocythemia (ET). Comparative analysis uncovers both shared and subtype‐specific molecular signatures, identifies a triple‐negative (TN)‐associated HSC population enriched with malignant traits, and reveals the ...

MOLECULAR IDENTIFICATION OF SEVERAL CLINICALLYIMPORTANT BACTERIA INCLUDING ENTEROBACTERIA BYPARTIAL 16S RIBOSOMAL RNA GENE SEQUENCE COMPARISON

open access: yesZdravniški Vestnik, 2008
BACKGROUND The correct identification of bacterial isolates is paramount for the correct diagnosis andtreatment of patients. The standard approach for bacterial identification relies on phenotypic tests, which are often time-consuming and unreliable when

Tie2‐Dependent Mechanisms Influence Leptomeningeal Collateral Dynamics and Reperfusion Following Stroke

open access: yesAdvanced Science, EarlyView.
This work demonstrates that endothelial EphA4 limits Tie2 activation and curbs leptomeningeal collateral expansion after ischemic stroke. Pharmacological activation of Tie2 by an Ang‐1 mimetic or genetic loss of EphA4 stimulates collateral vessel growth, improves cerebral perfusion, and enhances neurological recovery.

Use of RNA secondary structure for evolutionary relationships : investigating RNase P and RNase MRP : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Genetics at Massey University, New Zealand [PDF]

open access: yes, 1998
Bioinformatics is applied here to examine whether RNA secondary structure data can reflect distant evolutionary relationships. This is important when there is little confidence in sequence data such as when looking at the evolution of RNase MRP (MRP ...
