1. MicroRNAs unveiled: Nobel recognition of a revolutionary gene regulation mechanism
通讯作者:申恩志
The 2024 Nobel Prize in Physiology or Medicine honored Victor Ambros and Gary Ruvkun for their groundbreaking discovery of microRNAs (miRNAs), small non-coding RNA molecules that regulate gene expression by binding to target mRNAs. Initially identified in Caenorhabditis elegans, miRNAs were later found to be conserved across species and play crucial roles in development, immune response, and disease. miRNAs are transcribed as pri-miRNAs, processed into pre-miRNAs by Drosha/DGCR8, and matured by Dicer in the cytoplasm. They regulate gene expression post-transcriptionally through seed sequences, influencing processes like cell differentiation, apoptosis, and metabolism. Dysregulated miRNAs are implicated in cancers, cardiovascular diseases, neurological disorders, and metabolic conditions, making them promising therapeutic targets and diagnostic biomarkers. Beyond miRNAs, the Nobel recognition has spurred interest in other small RNAs, such as piRNAs and siRNAs, which also contribute to gene regulation and genome integrity. Future research will continue to explore the diverse roles of small RNAs and their potential applications in medicine and agriculture.

3. Induction of translation-suppressive G3BP1+stress granules and interferon-signaling cGAS condensates by transfected plasmid DNA
通讯作者:Vladimir Majerciak
Transfected plasmid DNA induces stress granule (SG) formation.
Transfected plasmid DNA induces cyclic guanosine monophosphate-adenosine monophosphate synthase (cGAS) condensates (cGC) and interferon responses.
Transfected plasmid DNA induced SG and cGC are mutually exclusive.
Inhibition of SG promotes transgene expression.
