MicroRNAs Regulate Key Effector Pathways of Senescence

Journal of Aging Research, 2011
MicroRNAs (miRNAs) are small (approximately 22 nt) noncoding endogenous RNA molecules that regulate gene expression and protein coding by base pairing with the 3′ untranslated region (UTR) of target mRNAs.

Correlation with basic differentiation processes of neurons [PDF]

, 1991
The development of the spinal cord involves the proliferation of neurons, their migration to well-defined areas, fiber outgrowth and synapse formation. The present study was designed to correlate the spatiotemporal pattern of expression of synaptophysin,

His‐MMDM: Multi‐Domain and Multi‐Omics Translation of Histopathological Images with Diffusion Models

Advanced Science, EarlyView.
His‐MMDM is a diffusion model‐based framework for scalable multi‐domain and multi‐omics translation of histopathological images, enabling tasks from virtual staining, cross‐tumor knowledge transfer, and omics‐guided image editing. ABSTRACT Generative AI (GenAI) has advanced computational pathology through various image translation models.

Roles of microRNA in liver cancer

Liver Research, 2018
Primary liver cancer is the fifth most common cancer and the third leading cause of cancer death worldwide. MicroRNAs (miRNAs) are small non-coding RNA molecules that downregulate gene expression by binding to the 3′-untranslated region of target miRNAs.

Genome-wide analysis of 30 -untranslated regions supports the existence of post-transcriptional regulons controlling gene expression in trypanosomes [PDF]

, 2013
In eukaryotic cells, a group of messenger ribonucleic acids (mRNAs) encoding functionally interrelated proteins together with the trans-acting factors that coordinately modulate their expression is termed a post-transcriptional regulon, due to their ...

The Transcription Factor FgSge1 Harnesses the SAGA Complex to Activate Mycotoxin Biosynthesis and Fungal Virulence

Advanced Science, EarlyView.
This study reveals the molecular mechanism by which the transcription factor FgSge1 regulates mycotoxin biosynthesis and virulence in Fusarium graminearum. FgSge1 binds to the TAARGTTT cis‐element, enabling self‐activation. It recruits the SAGA complex, promotes histone acetylation, and facilitates jet‐like chromatin remodeling, thereby activating ...

Evidence for RNA recombination between distinct isolates of Pepino mosaic virus. [PDF]

, 2010
Genetic recombination plays an important role in the evolution of virus genomes. In this study we analyzed publicly available genomic sequences of Pepino mosaic virus (PepMV) for recombination events using several bioinformatics tools.

TGFβ1 Activates Lnc‐APUE to Promote Tumor Metastasis via the Alu Element‐Driven STAU1‐Mediated Decay of CDH1 mRNA

Advanced Science, EarlyView.
We delineate a TGFβ1/SMAD/lnc‐APUE/E‐cadherin axis wherein TGFβ1 signaling activates lnc‐APUE; lnc‐APUE subsequently downregulates E‐cadherin expression via Alu element‐driven STAU1‐mediated decay of CDH1 mRNA, thereby promoting tumor metastasis. Our findings reveal a novel regulatory function for lnc‐APUE within the SMD pathway, elucidate a distinct ...

Role of Host MicroRNAs in Kaposi’s Sarcoma-Associated Herpesvirus Pathogenesis

Viruses, 2014
MicroRNAs (miRNAs) are small non-coding RNA species that can bind to both untranslated and coding regions of target mRNAs, causing their degradation or post-transcriptional modification.

Adipocyte‐Derived Exosomal miR‐5099 Mitigates M1 Macrophage Polarization and Adipose Inflammation via c‐Met/NF‐κB Axis to Improve Metabolic Health

Advanced Science, EarlyView.
Celastrol upregulates adipocyte‐derived exosomal miR‐5099, suppressing the macrophage c‐Met/NF‐κB axis to mitigate pro‐inflammatory M1 polarization and adipose inflammation. These miR‐5099‐enriched exosomes also act as endocrine signals targeting the liver, muscle, and adipocytes to significantly enhance systemic insulin sensitivity.
