Ufmylation: a potential modification for neurological diseases.

Neurological disorders are the leading health threats worldwide, characterized by impairments in consciousness, cognition, movement, and sensation, and can even lead to death. UFMylation is a novel post-translational modification (PTM) that serves as an important regulatory factor, promoting the complexity of protein structures and enhancing the diversity and specificity of functions. In UFMylation, ubiquitin-fold modifier 1 (UFM1) is covalently transferred to the primary amine of a lysine residue on the target protein through the synergistic action of three enzymes: the activating enzyme E1 of UFM1, the coupling enzyme E2 of UFM1, and the ligase E3.

Microproteins encoded by short open reading frames: Vital regulators in neurological diseases.

Short open reading frames (sORFs) are frequently overlooked because of their historical classification as non-coding elements or dismissed as "transcriptional noise". However, advanced genomic and proteomic technologies have allowed for screening and validating sORFs-encoded peptides, revealing their fundamental regulatory roles in cellular processes and sparking a growing interest in microprotein biology. In neuroscience, microproteins serve as neurotransmitters in signal transmission and regulate metabolism and emotions, exerting pivotal effects on neurological conditions such as nerve injury, neurogenic tumors, inflammation, and neurodegenerative diseases.

Overexpression of long noncoding RNA DUXAP8 inhibits ER-phagy through activating AKT/mTOR signaling and contributes to preeclampsia.

Preeclampsia (PE) is a life-threatening pregnancy-specific complication with controversial mechanisms and no effective treatment except delivery is available. Currently, increasing researchers suggested that PE shares pathophysiologic features with protein misfolding/aggregation disorders, such as Alzheimer disease (AD). Evidences have proposed defective autophagy as a potential source of protein aggregation in PE.

Insights into Enhancer RNAs: Biogenesis and Emerging Role in Brain Diseases.

Enhancers are cis-acting elements that control the transcription of target genes and are transcribed into a class of noncoding RNAs (ncRNAs) termed enhancer RNAs (eRNAs). eRNAs have shorter half-lives than mRNAs and long noncoding RNAs; however, the frequency of transcription of eRNAs is close to that of mRNAs. eRNA expression is associated with a high level of histone mark H3K27ac and a low level of H3K27me3.

Proteins in plasma as a potential biomarkers diagnostic for pelvic organ prolapse.

Background: Pelvic organ prolapse (POP) is the most common and widespread type of female pelvic floor dysfunction disease (PFD). At present, the diagnosis of POP is mainly based on a complicated systematic evaluation of the clinical phenotype, medical history, and relevant functional examinations. Rapid and simple tests that are based on biochemical biomarkers that surpass the sensitivity and specificity of the current methods for the diagnosis of POP will greatly facilitate the timely diagnosis and treatment of women with POP.

N6-methyladenosine RNA modification: A promising regulator in central nervous system injury.

In addition to DNA methylation, reversible epigenetic modification occurring in RNA has been discovered recently. The most abundant type of RNA methylation is N6-methyladenosine (m6A) modification, which is dynamically regulated by methylases ("writers"), demethylases ("erasers") and m6A-binding proteins ("readers"). As an essential posttranscriptional regulator, m6A can control mRNA splicing, processing, stability, export and translation.
