Single-Cell RNA Sequencing Uncovers Molecular Features Underlying the Disrupted Neurogenesis Following Traumatic Brain Injury.

Traumatic brain injury (TBI) is a leading cause of death and disability worldwide, with limited effective treatment strategies. Endogenous neural stem cells (NSCs) give rise to neurons and glial cells throughout life. However, NSCs are more likely to differentiate into glial cells rather than neurons at the lesion site after TBI and the underlying molecular mechanism remains largely unknown.

Remodeling of maternal mRNA through poly(A) tail orchestrates human oocyte-to-embryo transition.

Poly(A)-tail-mediated post-transcriptional regulation of maternal mRNAs is vital in the oocyte-to-embryo transition (OET). Nothing is known about poly(A) tail dynamics during the human OET. Here, we show that poly(A) tail length and internal non-A residues are highly dynamic during the human OET, using poly(A)-inclusive RNA isoform sequencing (PAIso-seq).

Characterization of Alzheimer's Disease-Associated Excitatory Neurons Single-Cell RNA Sequencing Analysis.

The detailed characteristics of neuronal cell populations in Alzheimer's disease (AD) using single-cell RNA sequencing have not been fully elucidated. To explore the characterization of neuronal cell populations in AD, this study utilized the publicly available single-nucleus RNA-sequencing datasets in the transgenic model of 5X familial Alzheimer's disease (5XFAD) and wild-type mice to reveal an AD-associated excitatory neuron population (C3:Ex.Neuron).

A pair of long intergenic non-coding RNA LINC00887 variants act antagonistically to control Carbonic Anhydrase IX transcription upon hypoxia in tongue squamous carcinoma progression.

Background: Long noncoding RNAs (lncRNAs) are important regulators in tumor progression. However, their biological functions and underlying mechanisms in hypoxia adaptation remain largely unclear.

Results: Here, we established a correlation between a Chr3q29-derived lncRNA gene and tongue squamous carcinoma (TSCC) by genome-wide analyses.

Long noncoding RNA PM maintains cerebellar synaptic integrity and Cbln1 activation via Pax6/Mll1-mediated H3K4me3.

Recent studies have shown that long noncoding RNAs (lncRNAs) are critical regulators in the central nervous system (CNS). However, their roles in the cerebellum are currently unclear. In this work, we identified the isoform 204 of lncRNA Gm2694 (designated as lncRNA-Promoting Methylation (lncRNA-PM)) is highly expressed in the cerebellum and derived from the antisense strand of the upstream region of Cerebellin-1 (Cbln1), a well-known critical cerebellar synaptic organizer.
