Integrated evolution of ribosomal RNAs, introns, and intron nurseries [PDF]

Genetica, 2018
The initial components of ribosomes first appeared more than 3.8 billion years ago during a time when many types of RNAs were evolving. While modern ribosomes are complex molecular machines consisting of rRNAs and proteins, they were assembled during early evolution by the association and joining of small functional RNA units. Introns may have provided

SUMOylation is a Translatable Target in Hypoxic MNPs Regulating Retinal Vasculopathy

Advanced Science, EarlyView.
During ischemic retinopathy/retinal vasculopathy, UBC9‐mediated SUMOylation in retinal macrophages enhances their pro‐angiogenic capacity via hypoxia‐induced SUMOylation of FUS at K327/K502. This modification suppresses FUS binding to the Vegfa mRNA 3’UTR, stabilizing transcripts and facilitating VEGFA production. Targeting UBC9 inhibition can serve as

TP53 R249S mutation in hepatic organoids captures the predisposing cancer risk

Hepatology, EarlyView., 2022
The systematic approach in elucidating the gain‐of‐function (GOF) roles of TP53 mutations in early liver carcinogenesis. Unique downstream targets of TP53 L3 mutations were identified from chormatin immunoprecipitation sequencing in HCC cell lines, followed by a series of validation assays to substantiate the exclusive transcriptional regulations ...

Novel Perspectives on Chloroplast tRNA Genomic and Structural Variations Imply the Evolution of Papilionoideae (Fabaceae)

Horticulturae
Papilionoideae is the most species-rich subfamily of the third largest angiosperm family Fabaceae. One constituent large group, the inverted-repeat-lacking clade (IRLC), is well-known for the broad loss of one IR copy.

Antagonistic Ghd7‐OsNAC42 Complexes Modulate Carbon and Nitrogen Metabolism to Achieves Superior Quality and High Yield in Rice

Advanced Science, EarlyView.
The complex centered on Ghd7 binds to numerous carbon and nitrogen metabolism genes on the genome through the corresponding motifs and transactivates the transcriptional expression of these carbon and nitrogen metabolism genes. With the assistance of OsNAC42 and other unknown Ghd7‐interacting proteins, this complex can regulate different metabolic ...

Double gene mutations of LRSAM1 and REEP1 and a new REEP1 mutation site found in a patient with amyotrophic lateral sclerosis with subjective paresthesia: A case report

Ibrain, EarlyView., 2023
Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease characterized by selective degeneration of upper and lower motor neurons. Leucine‐rich repeats and sterility α mutations in motif 1 (LRSAM1) has been proven to be involved in the pathogenesis of ALS.

EFTUD2 Regulates Cortical Morphogenesis via Modulation of Caspase‐3 and Aifm1 Splicing Pathways

Advanced Science, EarlyView.
EFTUD2, a spliceosomal GTPase linked to MFDM, regulates cortical development through apoptotic control. Conditional Eftud2 knockout in murine neural stem cells induces microcephaly and cortical disorganization, while pathogenic variants drive neuronal loss.
