ERβ/circAHNAK Axis Inhibits USP10–FMR1 Deubiquitination to Prevent m⁶A‐Mediated ADAM17 Decay and Promote Angiogenesis in Clear Cell Renal Cell Carcinoma

Advanced Science, EarlyView.
In clear cell renal cell carcinoma, estrogen receptor β (ERβ) upregulates circAHNAK, which competitively binds USP10 to prevent FMR1 deubiquitination, leading to FMR1 degradation. Loss of FMR1 hinders m⁶A‐dependent decay of ADAM17 mRNA, resulting in ADAM17 accumulation in tumor exosomes and enhanced angiogenesis.

Elevation in plasma tRNA fragments precede seizures in human epilepsy.

Journal of Clinical Investigation, 2019
Transfer RNAs (tRNAs) are a major class of noncoding RNA. Stress-induced cleavage of tRNA is highly conserved and results in tRNA fragments. Here we find specific tRNA fragments in plasma are associated with epilepsy.

Disrupted tRNA Genes and tRNA Fragments: A Perspective on tRNA Gene Evolution

Life, 2015
Transfer RNAs (tRNAs) are small non-coding RNAs with lengths of approximately 70–100 nt. They are directly involved in protein synthesis by carrying amino acids to the ribosome.

The RNA degradosome promotes tRNA quality control through clearance of hypomodified tRNA

Proceedings of the National Academy of Sciences of the United States of America, 2019
Significance The cellular mechanisms governing tRNA stability in bacteria are not well understood, and in contrast to eukaryotes, a bacterial system for degradation of mature tRNAs has not been described.

Ubc9‐Mediated SUMOylation of RPL3, an Unappreciated Mechanism against Hepatocyte Senescence by Repressing the DHX9‐p16 Axis

Advanced Science, EarlyView.
Liver aging is characterized by a decline in the expression of the SUMO‐conjugating enzyme Ubc9, resulting in reduced SUMOylation levels in hepatocytes, particularly in the case of ribosomal protein RPL3. Disruption of RPL3 SUMOylation increases its nuclear translocation. Interestingly, ribosome‐free RPL3 facilitates the recruitment of helicase DHX9 to

Mitochondrial stress in advanced fibrosis and cirrhosis associated with chronic hepatitis B, chronic hepatitis C, or nonalcoholic steatohepatitis

Hepatology, EarlyView., 2022
Adaptive mitochondrial mechanisms allow mitochondrial resilience and prevent the worsening of fibrosis, while deregulation of these mechanisms promotes the progression from no/minimal‐mild (F0‐F2) fibrosis to advanced fibrosis and cirrhosis (F3‐F4). Abstract Background and Aims Hepatitis B virus (HBV) infection causes oxidative stress (OS) and alters ...

Multiple Layers of Stress-Induced Regulation in tRNA Biology

Life, 2016
tRNAs are the fundamental components of the translation machinery as they deliver amino acids to the ribosomes during protein synthesis. Beyond their essential function in translation, tRNAs also function in regulating gene expression, modulating ...

Site‐Specific Mitochondrial RNA N1‐Methyladenosine Demethylation via an Engineered MTS‐PUF‐ALKBH3 Fusion Protein

Advanced Science, EarlyView.
A CRISPR‐free mitochondrial RNA m1A demethylation (MRD) editor combining MTS, PUF proteins, and ALKBH3 enables precise m1A removal from mitochondrial mRNA and tRNA, which influences mitochondrial protein levels, cellular proliferation, ATP production, and mitochondrial respiration. Subsequently, in vivo demethylation of the m1A modification is achieved
