5'tiRNA-35-GlyTCC-3 and 5'tiRNA-33-CysGCA-11 target BMP6, CUL1 and SPR of non-syndromic cleft palate.

Background: tsRNAs are novel small non-coding RNAs that play important regulatory roles in gene expression, translation, transcription, and epigenetic modification through proteins or mRNAs and may be therapeutic targets for certain diseases. The etiology of non-syndromic cleft palate-only is complex and the pathogenesis is poorly understood, non-coding RNAs play important roles in its development.

Methods: The tsRNAs of patients with simple cleft palate were compared with healthy individuals using small RNA microarray, bioinformatic analysis, quantitative real-time transcription polymerase chain reaction, and the effects measured using immunohistochemical staining.

Vitamin D binding protein and receptor prevalence in a large population with periodontitis: single nucleotide polymorphism and transcriptomic profiling.

Background: There is an ongoing controversy regarding the expression of vitamin D receptor (VDR) and binding protein (VDBP) genes, as well as their polymorphisms, in periodontitis. We examined eight single nucleotide polymorphisms (SNPs) and performed a transcriptome-level bioinformatics analysis to clarify their relationship with periodontitis.

Methods: To explore VDR and VDBP polymorphisms, 600 subjects were included, including 307 patients with chronic periodontitis (CP) and 293 healthy controls.

Single cell multiomic analysis reveals diabetes-associated β-cell heterogeneity driven by HNF1A.

Broad heterogeneity in pancreatic β-cell function and morphology has been widely reported. However, determining which components of this cellular heterogeneity serve a diabetes-relevant function remains challenging. Here, we integrate single-cell transcriptome, single-nuclei chromatin accessibility, and cell-type specific 3D genome profiles from human islets and identify Type II Diabetes (T2D)-associated β-cell heterogeneity at both transcriptomic and epigenomic levels.

Comparison of Various Nuclear Localization Signal-Fused Cas9 Proteins and mRNA for Genome Editing in Zebrafish.

The clustered regularly interspaced short palindromic repeats (CRISPR)/Cas9 system has been proven to be an efficient and precise genome editing technology in various organisms. However, the gene editing efficiencies of Cas9 proteins with a nuclear localization signal (NLS) fused to different termini and mRNA have not been systematically compared. Here, we compared the ability of Cas9 proteins with NLS fused to the N-, C-, or both the N- and C-termini and N-NLS-Cas9-NLS-C mRNA to target two sites in the gene and two sites in the gene related to pigmentation in zebrafish.
