Self-interacting Proteins (SIPs) plays a critical role in a series of life function in most living cells. Researches on SIPs are important part of molecular biology. Although numerous SIPs data be provided, traditional experimental methods are labor-intensive, time-consuming and costly and can only yield limited results in real-world needs. Hence,it's urgent to develop an efficient computational SIPs prediction method to fill the gap. Deep learning technologies have proven to produce subversive performance improvements in many areas, but the effectiveness of deep learning methods for SIPs prediction has not been verified.

Urban rodents and house shrews are closely correlated in terms of location with humans and can transmit many pathogens to them. Hepatitis E has been confirmed to be a zoonotic disease. However, the zoonotic potential of rat HEV is still unclear. The aim of this study was to determine the prevalence and genomic characteristics of hepatitis E virus (HEV) in rodents and house shrews.

Epithelial-to-mesenchymal transition (EMT) contributes to the invasion and metastasis of epithelial tumors. Sirtuin 6 (SIRT6), an NAD-dependent deacetylase, is known to promote metastasis of non-small cell lung cancer (NSCLC).

Flavonoids are important components that confer upon tea plants a unique flavour and health functions. However, the traditional breeding method for selecting a cultivar with a high or unique flavonoid content is time consuming and labour intensive. High-density genetic map construction associated with quantitative trait locus (QTL) mapping provides an effective way to facilitate trait improvement in plant breeding. In this study, an F1 population (LJ43×BHZ) was genotyped using 2b-restriction site-associated DNA (2b-RAD) sequencing to obtain massive single nucleotide polymorphism (SNP) markers to construct a high-density genetic map for a tea plant. Furthermore, QTLs related to flavonoids were identified using our new genetic map.

Cisplatin has been widely used for the treatment of cancer and its antitumour activity is attributed to its capacity to form DNA adducts, predominantly at guanine residues, which impede cellular processes such as DNA replication and transcription. However, there are associated toxicity and drug resistance issues which plague its use. This has prompted the development and screening of a range of chemotherapeutic drug analogues towards improved efficacy. The biological properties of three novel platinum-based compounds consisting of varying cis-configured ligand groups, as well as a commercially supplied compound, were characterised in this study to determine their potential as anticancer agents.

Catheter-related infection (CRI) is one of the serious challenges in clinical practice. This preliminary clinical study aimed to examine whether next-generation sequencing (NGS) targeting 16S rDNA, which was PCR-amplified directly from the tip of a central venous catheter (CVC), can be used to identify causative pathogens in CRI, compared to the culture method.

Bioinformatics tools have been developed to interpret gene expression data at the gene set level, and these gene set based analyses improve the biologists' capability to discover functional relevance of their experiment design. While elucidating gene set individually, inter-gene sets association is rarely taken into consideration. Deep learning, an emerging machine learning technique in computational biology, can be used to generate an unbiased combination of gene set, and to determine the biological relevance and analysis consistency of these combining gene sets by leveraging large genomic data sets.

As the incidence of cardiovascular diseases increases, the use of antiplatelet therapy is widely recognized. This presents clinicians with the challenge of balancing the risk of thrombotic and bleeding complications. Platelet dysfunction is one of the causes of postoperative bleedings and their etiology is not fully understood. Platelets receptors point-of-care investigation is of a remarkable value in assessing patients risk of bleeding. Reliable assessment of platelet function can improve treatment. The aim of this study was to evaluate the activity of platelet receptors in patients qualified for cardiac surgery, taking into account organ dysfunctions and pharmacological therapy applied in these patients.

Gene signatures are important to represent the molecular changes in the disease genomes or the cells in specific conditions, and have been often used to separate samples into different groups for better research or clinical treatment. While many methods and applications have been available in literature, there still lack powerful ones that can take account of the complex data and detect the most informative signatures.

Our understanding of eukaryotic gene regulation is limited by the complexity of protein-DNA interactions that comprise the chromatin landscape and by inefficient methods for characterizing these interactions. We recently introduced CUT&RUN, an antibody-targeted nuclease cleavage method that profiles DNA-binding proteins, histones and chromatin-modifying proteins in situ with exceptional sensitivity and resolution.

Many physiological processes in our body are controlled by the biological clock and show circadian rhythmicity. It is generally accepted that a robust rhythm is a prerequisite for optimal functioning and that a lack of rhythmicity can contribute to the pathogenesis of various diseases. Here, we tested in a heterogeneous laboratory zebrafish population whether and how variation in the rhythmicity of the biological clock is associated with the coping styles of individual animals, as assessed in a behavioural assay to reliably measure this along a continuum between proactive and reactive extremes.

To analyze the clinical audiological characteristics of X-Linked Alport syndrome (XLAS) in males and their relationships with genotypes.

Colorectal cancer (CRC) is a major cause of morbidity and mortality worldwide, but these can be reduced significantly with population screening using annual fecal occult blood tests (FOBT)A positive FOBT requires timely follow-up with colonoscopy to maximize screening benefits.. Several barriers to follow-up have been identified, with patient health behaviors and choices comprising a significant part of these. The Patient Activation Measure (PAM) assesses knowledge, skills, beliefs, and confidence in managing health. Increased patient activation is related to positive health outcomes. The aim of this study is to examine the association between patient empowerment, as reflected in the PAM, and follow-up colonoscopy within 90 days of a positive FOBT result.

From a screening study of various potential inhibitors for cholinesterases (ChEs), compound (rac)-1 (4-((3-hydroxy-2-oxo-3-phenylindolin-1-yl) methyl) piperidin-1-ium chloride) showed an IC50 of 18 μM for butyrylcholinesterase (BuChE). Herein we present a toxicological and pharmacological evaluation of (rac)-1 to determine its potential for use as an alternative ChE inhibitor for the treatment of Alzheimer's disease. The strategy adopted included in vivo and ex vivo studies with mouse models, Molecular Modelling and Saturation Transfer Difference (STD) NMR studies. Preliminary molecular docking studies were conducted with both (R) and (S)-1 with acetylcholinesterase (AChE) and BuChE, prior to advancing to the mouse model, and indeed favorable interactions were observed, with (R)-1 showing the best binding with AChE and (S)-1 with BuChE. STD-NMR studies were used to successfully validate these results. Toxicological studies were also conducted using the Artemia salina model, with donepezil as reference. It was found that in the in vivo mouse studies that (rac)-1 presented a slightly better inhibition of AChE (0.096 µmol.min-1.mg-1) than donepezil (0.112 µmol.min-1.mg-1) and the same level of inhibition for BuChE as donepezil (0.014 µmol.min-1.mg-1).

Glycosylphosphatidylinositol-anchored proteins were reported to be involved in many developmental progresses in Arabidopsis. Here I report that, a group of homologous glycosylphosphatidylinositol-anchored proteins from SKU5-Similar family regulate seedling root development of Arabidopsis through controlling cell polar expansion and cell wall synthesis. Due to the irregular expansion of root cells and the defective synthesis of cell walls, their knockout mutants generated shorter roots with irregularly shaped root cells, and thicker cell walls.

The precise mechanism of osteolysis induced by tumors infiltrating into the bone remains unclear. The main hypothesis is that tumor cells generate receptor activator of nuclear factor kappa-B ligand (RANKL), tumor necrosis factor-alpha (TNF-α), or other molecules that activate the expression of RANKL in osteoblasts, osteocytes, or bone marrow stromal cells. Administration of bisphosphonates or anti-RANKL antibody drugs, which suppress systemic bone resorption, prevents osteolysis induced by tumors infiltrating into the bone. However, these therapeutic agents may cause medication-related osteonecrosis of the jaw. In this study, we found a novel tumor-associated osteoclastogenesis pathway in osteoclast precursor cells. Co-culture with human oral squamous cell carcinoma cells, 3A or NEM, or culture with each of their conditioned medium induced many osteoclasts from osteoclast precursor cells, which were generated by a 24-h pretreatment of RANKL or TNF-α. Osteoprotegerin, a decoy RANKL receptor, denosumab, an anti-RANKL antibody drug, and infliximab, an anti-TNF-α antibody drug, did not prevent this tumor-associated osteoclastogenesis. Quantitative RT-PCR analysis showed that the expression of NFATc1 was decreased in this tumor-associated osteoclastogenesis, which was suggested to be independent of NFATc1. These results revealed a novel pathway for tumor-associated osteoclastogenesis, which may be a new therapeutic target for osteolysis induced by tumors infiltrating into the bone without affecting systemic bone metabolism.

Microglia are the resident macrophages of the central nervous system (CNS). They have important physiological functions in maintaining tissue homeostasis but also contribute to CNS pathology. Microglia respond to changes in the microenvironment, and the resulting reactive phenotype can be very diverse, with both neuroinflammatory and neuroprotective properties, illustrating the plasticity of these cells. Recent progress in understanding the autoimmune neuroinflammatory disease multiple sclerosis (MS) and its animal model experimental autoimmune encephalomyelitis suggests major roles for microglia in the disease, which have drastically changed our view on the function of microglia in MS.

Multiple peptide receptors are co-expressed in many types of cancers. Arg-Gly-Asp (RGD) and GE11 peptides specifically target integrin αVβ3 and EGFR, respectively. Recently, we designed and synthesized a heterodimer peptide NOTA-c(RGDyK)-GE11 (NOTA-RGD-GE11). The aim of this study was to investigate the characteristics of NOTA-RGD-GE11 for dual receptor imaging.

There is considerable evidence that exposure to fine particulate matter (PM2.5) air pollution is associated with a variety of adverse health outcomes. However, true exposure-outcome associations are hampered by measurement issues, including compliance and exposure misclassification.

The development of the aortic arch is a complex process that involves remodeling of the bilaterally symmetrical pharyngeal arch arteries (PAAs) into the mature asymmetric aortic arch. Retinoic acid signaling is a key regulator of this process by directing patterning of the second heart field (SHF), formation of the caudal PAAs and subsequent remodeling of the PAAs to form the aortic arch. Here, we identify the HECTD1 ubiquitin ligase as a novel modulator of retinoic acid signaling during this process. Hectd1opm/opm homozygous mutant embryos show a spectrum of aortic arch abnormalities that occur following loss of 4th PAAs and increased SHF marker expression. This sequence of defects is similar to phenotypes observed in mutant mouse models with reduced retinoic acid signaling. Importantly, HECTD1 binds to and influences ubiquitination of the retinoic acid receptor, alpha (RARA). Furthermore, reduced activation of a retinoic acid response element (RARE) reporter is detected in Hectd1 mutant cells and embryos. Interestingly, Hectd1opm/+ heterozygous embryos exhibit reduced retinoic acid signaling, along with intermediate increased expression of SHF markers; however, heterozygotes show normal development of the aortic arch. Decreasing retinoic acid synthesis by reducing Raldh2 (also known as Aldh1a2) gene dosage in Hectd1opm/+ heterozygous embryos reveals a genetic interaction. Double heterozygous embryos show hypoplasia of the 4th PAA and increased incidence of a benign aortic arch variant, in which the transverse arch between the brachiocephalic and left common carotid arteries is shortened. Together, our data establish that HECTD1 is a novel regulator of retinoic acid signaling required for proper aortic arch development.
