Histone methylation is a modification which occurs in the N-terminal peptide chains of the histone nucleosome. The 4th, 9th, 27th, 36th and 79th lysines in N-terminal peptide chain of histone H3 are hot spots for this modification, including mono-, di-, and tri-methylation. H3K27me3 is the tri-methylation modification on histone H3 lysine 27, which mainly functions as a transcriptional repressor regulating skeletal muscle development.

Our previous research found that metallothionein 1M (MT1M) was a novel potential PTC associated gene in thyroid cancer. In the present study, the expression status and prognostic value of MT1M expression were investigated in thyroid cancer.

Quantum clock synchronization schemes utilizing frequency-entangled pulses have flourished for their potentially superior precision to the classical protocols. In this Letter, a new experimental record based on the second-order quantum interference algorithm is reported, to the best of our knowledge. The synchronization accuracy between two parties separated by a 6 km fiber coiling link, which is evaluated by the time offset shift relative to that with the fibers removed, has been measured to be 13±1 ps.

However, the relevance of MARCKS in gastric cancer (GC) needs to be elucidated. MATERIAL AND METHODS The abundance of MARCKS in GC tissues was assessed using techniques of immunohistochemistry (IHC) and quantitative real-time PCR (qRT-PCR).

We document here milk provisioning in a jumping spider, which compares functionally and behaviorally to lactation in mammals. The spiderlings ingest nutritious milk droplets secreted from the mother's epigastric furrow until the subadult stage.

Many aspects of PCV3 infection biology and pathogenesis, however, remain unknown. Here, we used a PCV3 virus stock from the rescue of an infectious PCV3 DNA clone to intranasally inoculate 4- and 8-week-old specific-pathogen-free piglets for evaluation of PCV3 pathogenesis.

The GDP-mannose pyrophosphate synthetase (GMPase) is a key factor of ascorbic acid (AsA) synthesis in rice roots. The present study showed that the transcript of was induced by salt stress in roots, but not in leaves.

It inhibits the efficiency of homologous recombination (HR) by competing for DSB targets. To improve the efficiency of HR in porcine fetal fibroblasts (PFFs), several RNA interference (RNAi) systems were designed to knockdown NHEJ key molecules, such as polynucleotide kinase/phosphatase (PNKP), DNA ligase IV (LIG4) and NHEJ1.

Furthermore, it is not clear which is more related to conservation outcomes-the management itself or local people's perceptions of the management. We measured objective (reports by park staff) and subjective (reports by local people) levels of community outreach and law enforcement based on responses to 374 questionnaires.

Genomic editing to correct disease-causing mutations is a promising approach for the treatment of human diseases. As a simple and programmable nuclease-based genomic editing tool, the clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated protein 9 (Cas9) system has substantially improved the ability to make precise changes in the human genome. Rapid development of CRISPR-based technologies in recent years has expanded its application scope and promoted CRISPR-based therapies in preclinical trails.

The main DNA repair pathways, nonhomologous end joining (NHEJ) and homology-directed repair (HDR), are complementary to each other; hence, interruptions of the NHEJ pathway can favor HDR. Improving HDR efficiency in animal primary fibroblasts can facilitate the generation of gene knock-in animals with agricultural and biomedical values by somatic cell nuclear transfer. In this study, we used siRNA to suppress the expression of Ku70 and Ku80, which are the key factors in NHEJ pathway, to investigate the effect of Ku silencing on the HDR efficiency in pig fetal fibroblasts.
