The role of noncoding RNAs in the tumor microenvironment of hepatocellular carcinoma

open access: yesActa Biochimica et Biophysica Sinica, 2023
Hepatocellular carcinoma (HCC) is the leading fatal malignancy worldwide. The tumor microenvironment (TME) can affect the survival, proliferation, migration, and even dormancy of cancer cells.

Long Noncoding RNA PCALRx Interacts with Pyruvate Carboxylase to Drive Multi-Organ Developmental Toxicity in Zebrafish Embryos Exposed to Amoxicillin. [PDF]

open access: yesAdv Sci (Weinh)
Embryonic amoxicillin exposure disrupts multi‐organ development in zebrafish larvae through a lncRNA–metabolic enzyme regulatory axis. PCALRx associates with pyruvate carboxylase, promotes PC protein ubiquitination, and impairs mitochondrial energy metabolism, while vitamin B1 partially restores PC‐centered metabolic function and developmental outcomes.

Detection of genome-scale ordered RNA structure (GORS) in genomes of positive-stranded RNA viruses:Implications for virus evolution and host persistence [PDF]

open access: yes, 2004
Discrete RNA secondary and higher-order structures, typically local in extent, play a fundamental role in RNA virus replication. Using new bioinformatics analysis methods, we have identified genome-scale ordered RNA structure (GORS) in many genera and ...

A new synthetic protocol for coumarin amino acid

open access: yesBeilstein Journal of Organic Chemistry, 2013
The hydrochloride of the racemic amino acid (2-(7-hydroxycoumarin-4-yl)ethyl)glycine, which can serve as a fluorescent probe in proteins, and two halogen derivatives of it, were synthesized by using a new synthetic protocol in five steps.

A comparative analysis of lncRNAs in prostate cancer exosomes and their parental cell lines

open access: yesGenomics Data, 2016
Prostate cancer is the second leading cancer in men world-wide. Due to its heterogeneous nature, a considerable amount of research effort has been dedicated in identifying effective clinical biomarkers with a focus on proteins, messenger RNA and ...

Structural insights into the dynamics and function of the C-terminus of the E. coli RNA chaperone Hfq [PDF]

open access: yes, 2011
The hexameric Escherichia coli RNA chaperone Hfq (Hfq(Ec)) is involved in riboregulation of target mRNAs by small trans-encoded RNAs. Hfq proteins of different bacteria comprise an evolutionarily conserved core, whereas the C-terminus is variable in ...

Distinct MicroRNA Subcellular Size and Expression Patterns in Human Cancer Cells

open access: yesInternational Journal of Cell Biology, 2012
Introduction. Small noncoding RNAs have important regulatory functions in different cell pathways. It is believed that most of them mainly play role in gene post-transcriptional regulation in the cytoplasm.

Patterns of selective constraints in noncoding DNA of rice [PDF]

open access: yes, 2007
Background Several studies have investigated the relationships between selective constraints in introns and their length, GC content and location within genes. To date, however, no such investigation has been done in plants.

Microprocessor Activity Controls Differential miRNA Biogenesis In Vivo

open access: yesCell Reports, 2014
In miRNA biogenesis, pri-miRNA transcripts are converted into pre-miRNA hairpins. The in vivo properties of this process remain enigmatic. Here, we determine in vivo transcriptome-wide pri-miRNA processing using next-generation sequencing of chromatin ...
