Topological evolution of coexpression networks by new gene integration maintains the hierarchical and modular structures in human ancestors

We analyze the global structure and evolution of human gene coexpression networks driven by new gene integration. When the Pearson correlation coefficient is greater than or equal to 0.5, we find that the coexpression network consists of 334 small components and one “giant” connected subnet comprising of 6317 interacting genes. This network shows the properties of power-law...

Origination and evolution of orphan genes and de novo genes in the genome of Caenorhabditis elegans

Orphan genes that lack detectable homologues in other lineages could contribute to a variety of biological functions. However, their origination and function mechanisms remain largely unknown. Herein, through a comprehensive and systematic computational pipeline, we identified 893 orphan genes in the lineage of C. elegans, of which only a low fraction (0.9%) were derived from...

Complete loss of RNA editing from the plastid genome and most highly expressed mitochondrial genes of Welwitschia mirabilis

Comparative genomics among gymnosperms suggested extensive loss of mitochondrial RNA editing sites from Welwitschia mirabilis based on predictive analysis. However, empirical or transcriptome data to confirm this massive loss event are lacking, and the potential mechanisms of RNA site loss are unclear. By comparing genomic sequences with transcriptomic and reversetranscription...

The function and potential drug targets of tumour-associated Tregs for cancer immunotherapy

Regulatory T cells (Tregs) play an important role in maintaining self-tolerance and immune homeostasis, but they also play a negative role in evoking effective antitumour immune responses. There is ample evidence indicating that the depletion of Tregs or the inhibition of Treg function will enhance antitumour effects. However, it is unclear which surface molecules of Tregs are...

Enhancer RNAs: a missing regulatory layer in gene transcription

Enhancers and super-enhancers exert indispensable roles in maintaining cell identity through spatiotemporally regulating gene transcription. Meanwhile, active enhancers and super-enhancers also produce transcripts termed enhancer RNAs (eRNAs) from their DNA elements. Although enhancers have been identified for more than 30 years, widespread transcription from enhancers are just...

Genome-wide analysis identified 17 new loci influencing intraocular pressure in Chinese population

Intraocular pressure (IOP) is a major risk factor for glaucoma. Genetic determinants of intraocular pressure can provide critical insights into the genetic architecture of glaucoma and, as a result, open new avenues for therapeutic intervention. We performed a genome-wide association study and replication analysis of 8,552 Chinese participants. In the genome-wide association...

Chinese society of cardiology expert consensus statement on the diagnosis and treatment of adult fulminant myocarditis

Fulminant myocarditis is primarily caused by infection with any number of a variety of viruses. It arises quickly, progresses rapidly, and may lead to severe heart failure or circulatory failure presenting as rapid-onset hypotension and cardiogenic shock, with mortality rates as high as 50%–70%. Most importantly, there are no treatment options, guidelines or an expert consensus...

Mechanism underlying the retarded nuclear translocation of androgen receptor splice variants

As shown in our previous study, two alternatively spliced androgen receptor (AR) variants, which are exclusively expressed in the granulosa cells of patients with polycystic ovary syndrome, exhibit retarded nuclear translocation compared with wild-type AR. However, researchers have not yet determined whether these abnormalities correlate with heat shock protein 90 (HSP90) and...

A thorough analysis of diabetes research in China from 1995 to 2015: current scenario and future scope

The prevalence of diabetes has increased dramatically over the past three decades, and currently, China has the largest number of diabetics worldwide; this number continues to grow and puts ongoing strains on the medical resources. In this review, we reviewed the diabetes research conducted in China from 1995 to 2015 with the aim of providing new insights regarding the current...

A combination of follicle stimulating hormone, estradiol and age is associated with the pregnancy outcome for women undergoing assisted reproduction: a retrospective cohort analysis

To investigate the effect of basal hormone levels including follicle stimulating hormone (FSH) and estradiol (E2) and age on the pregnancy outcomes in women undergoing in vitro fertilization and embryo transfer (IVF-ET), we designed a retrospective cohort analysis and collected information of patients undergoing IVF between January 2014 and April 2017. We found that young women...

Behavioral interventions to eliminate fear responses

Fear memory underlies anxiety-related disorders, including posttraumatic stress disorder (PTSD). PTSD is a fear-based disorder, characterized by difficulties in extinguishing the learned fear response and maintaining extinction. Currently, the first-line treatment for PTSD is exposure therapy, which forms an extinction memory to compete with the original fear memory. However, the...

A potential strategy for treating atherosclerosis: improving endothelial function via AMP-activated protein kinase

Endothelial dysfunction is caused by many factors, such as dyslipidemia, endoplasmic reticulum (ER) stress, and inflammation. It has been demonstrated that endothelial dysfunction is the initial process of atherosclerosis. AMP-activated protein kinase (AMPK) is an important metabolic switch that plays a crucial role in lipid metabolism and inflammation. However, recent evidence...

Defect-related luminescent bur-like hydroxyapatite microspheres induced apoptosis of MC3T3-E1 cells by lysosomal and mitochondrial pathways

When orthopedic joints coated by hydroxyapatite (HA) were implanted in the human body, they release wear debris into the surrounding tissues. The generation and accumulation of wear particles will induce aseptic loosening. However, the potential bioeffect and mechanism of HA-coated orthopedic implants on bone cells are poorly understood. In this study, defect-related luminescent...

Nanomedicine for obesity treatment

Obesity, as a chronic condition, has been a serious public health issue over the last decades both in the affluent Western world and developing countries. As reported, the risk of several serious diseases increases with weight gain, including type 2 diabetes, coronary heart disease, cancer, and respiratory diseases. In addition to lifestyle modifications, pharmacotherapy has...

Nanotherapeutic approaches targeting angiogenesis and immune dysfunction in tumor microenvironment

Tumor microenvironment (TME) comprising cellular and non-cellular components is a major source of cancer hallmarks. Notably, angiogenesis responsible for normal physiological remodeling process can otherwise harness vessel abnormalities during tumorigenesis eliciting severe therapeutic inefficiency. Currently, FDA approved antiangiogenic drugs have only shown modest clinical...
