Mean texture depth (MTD) is pivotal in assessing the skid resistance of asphalt pavements and ensuring road safety. This study focuses on developing an automated system for extracting features evaluating MTD based pavement images. The contributions this work are threefold: firstly, it proposes economical method to acquire three-dimensional (3D) data; secondly, enhances 3D image processing techniques formulates that represent various aspects texture; thirdly, establishes multivariate...
Abstract Genome editing technologies hold tremendous potential in biomedical research and drug development. Therefore, it is imperative to discover gene tools with superior cutting efficiency, good fidelity, fewer genomic restrictions. Here, we report a CRISPR/Cas9 from Faecalibaculum rodentium , which characterized by simple PAM (5′-NNTA-3′) guide RNA length of 21–22 bp. We find that FrCas9 could achieve comparable efficiency specificity SpCas9. Interestingly, the presents palindromic...
Abstract Human papillomavirus (HPV) integration is a critical step in cervical cancer development; however, the oncogenic mechanism at genome-wide transcriptional level still poorly understood. In this study, we employed integrative analysis on multi-omics data of six HPV-positive and three HPV-negative cell lines. Through HPV detection, super-enhancer (SE) identification, SE-associated gene expression extrachromosomal DNA (ecDNA) investigation, aimed to explore influence integration. We...
Prime editing (PE) holds tremendous potential in the treatment of genetic diseases because it can install any desired base substitution or local insertion/deletion. However, full-length PE effector size (6.3-kb) is beyond packaging capacity adeno-associated virus (AAV), hindering its clinical translation. Various splitting strategies have been used to improve delivery, but always accompanied by compromised efficiency. Here, we developed a modular and efficient SunTag-PE system that splits...
Zinc-finger nucleases (ZFNs), transcription activator-like endonucleases (TALENs), and CRISPR-associated Cas9 are three major generations of genome editing tools. However, no parallel comparison about the efficiencies off-target activity has been reported, which is critical for final clinical decision. We first time developed genome-wide unbiased identification double-stranded breaks enabled by sequencing (GUIDE-seq) method in ZFNs TALENs with novel bioinformatics algorithms to evaluate...
A genome editing tool targeting the high-risk human papillomavirus (HPV) oncogene is a promising therapeutic strategy to treat HPV-related cervical cancer. To improve gene knockout efficiency, we developed chain reaction (GKCR) method for continually generating mutagenic disruptions and used this disrupt HPV18 E6 E7 genes. We verified that GKCR Cas9/guide RNA (gRNA) cassettes could integrated into targeted loci via homology-independent insertion (HITI). The qPCR results revealed enabled...
CRISPR-associated (Cas) nucleases are multifunctional tools for gene editing. Cas12a possesses several advantages, including the requirement of a single guide RNA and high fidelity Here, we tested three orthologs from human gut samples identified LtCas12a that utilizes TTNA protospacer adjacent motif (PAM) distinct canonical TTTV PAM but with equivalent cleavage ability specificity. These features significantly broadened targeting scope family. Furthermore, developed sensitive, accurate,...
Integration of oncogenic DNA viruses into the human genome is a key step in most virus-induced carcinogenesis. Here, we constructed virus integration site (VIS) Atlas database, an extensive collection breakpoints for three prevalent oncoviruses, papillomavirus, hepatitis B virus, and Epstein-Barr based on next-generation sequencing (NGS) data, literature, experimental data. There are 63,179 47,411 junctional sequences with full annotations deposited VIS comprising 47 genotypes 17 disease...
Abstract Background Hypertrophic cardiomyopathy (HCM) is a prevalent genetic heart disease caused by variants in sarcomere genes like MYH7, which accounts for 40% of cases with 75% being heterozygous. HCM shows incomplete penetrance, where mutant allele expression correlates severity. Thus, allele-specific suppression potential therapy. While RNAi or CRISPR/Cas9 showed moderate efficacy, low level MYH7 associated the risk failure and dilated cardiomyopathy. We hypothesized CRISPR-based...
Abstract Prime editing (PE) holds tremendous potential in the treatment of genetic diseases because it can install any desired base substitution or local insertion/deletion. However, full-length PE effector size (6.3-kb) was beyond packaging capacity adeno-associated virus (AAV), hindering its clinical transformation. Various splitting strategies have been used to improve delivery, but always accompanied by compromised efficiency. Here, we developed a modular and efficient SunTag-PE system...
