Article Synopsis
  • Activation of endogenous neural stem cells (NSCs) can promote healing after spinal cord injuries, but methods to regulate these cells are limited.
  • This study found that nicotinamide riboside enhances the growth of NSCs and helps them differentiate into neurons, leading to improved lower limb motor function after injury.
  • The mechanism behind this involves the activation of the Wnt signaling pathway through the LGR5 gene, as blocking this pathway hinders the effects of nicotinamide riboside on NSC proliferation.

Article Synopsis
  • After spinal cord injury (SCI), the immune system becomes activated, leading to an influx of immune cells into the injured area; however, there is a lack of research on immune subtypes and markers using advanced single-cell sequencing.
  • Researchers analyzed spinal cord samples over three time points post-SCI to identify differentiation-related genes and molecular subtypes using various bioinformatics techniques, including pseudo-time analysis and consensus clustering.
  • The study discovered two main molecular subtypes (C1 and C2) with differing immune responses and identified three potential biomarkers (C1qa, Lgals3, and Cd63) that could help with diagnostics following SCI.

Certified RNA reference materials are indispensable for assessing the reliability of RNA sequencing to detect intrinsically small biological differences in clinical settings, such as molecular subtyping of diseases. As part of the Quartet Project for quality control and data integration of multi-omics profiling, we established four RNA reference materials derived from immortalized B-lymphoblastoid cell lines from four members of a monozygotic twin family. Additionally, we constructed ratio-based transcriptome-wide reference datasets between two samples, providing cross-platform and cross-laboratory 'ground truth'.

Background: Ground-glass opacity (GGO)-like lung adenocarcinoma (LUAD) has been detected increasingly in the clinic and its inert property and superior survival indicate unique biological characteristics. However, we do not know much about them, which hampers identification of key reasons for the inert property of GGO-like LUAD.

Methods: Using whole-exome sequencing and RNA sequencing, taking into account both radiological and pathological classifications of the same 197 patients concomitantly, we systematically interrogate genes driving the progression from GGO to solid nodule and potential reasons for the inertia of GGO.

Article Synopsis
  • The inflammatory response after spinal cord injury (SCI) can worsen the condition due to inflammatory factors and macrophage polarization towards an unhealthy M1 type.
  • Ang-(1-7), generated from Ang II, interacts with the Mas receptor (MasR) to help modulate inflammation and reduce oxidative stress.
  • Research on rats indicates that activating the Ang-(1-7)/MasR axis enhances recovery from inflammation and injury by shifting macrophage polarization towards a healthier M2 type and improving functional outcomes through the TLR4/NF-κB signaling pathway.

Per- and polyfluoroalkyl substances (PFASs) are potentially neurotoxic compounds. Levels of PFASs in cerebrospinal fluid (CSF) could directly reflect their potential harm to the central nervous system. Because of the variety of PFASs and the rarity of CSF, there is an urgent need to establish a rapid online method to detect a broad spectrum of PFASs accurately and simultaneously by consuming a small amount of CSF.
