A Novel GATA Factor Transcriptionally Represses Yolk Protein Precursor Genes in the Mosquito Aedes aegypti via Interaction with the CtBP Corepressor
In anautogenous mosquitoes, vitellogenesis, the key event in egg maturation, requires a blood meal. Consequently, mosquitoes are vectors of many devastating human diseases. An important adaptation for anautogenicity is the previtellogenic arrest (the state of arrest) preventing the activation of the yolk protein precursor (YPP) genes Vg and VCP prior to blood feeding. A novel GATA factor ...

The Influence of Experience and Credential Status on Perceptions of Agency Competency
Contributions made by the environmental health (EH) workforce in reducing human disease are some of the most significant to public health. A shrinking workforce and increased work complexity have called for workforce training in the 10 essential public health services. The preliminary study discussed here assesses perceived competency of the Kansas EH workforce in the 10 essential public health ...

DNA nanoparticles for gene delivery to cells and tissue
The development over the past decade of methods for delivering genes to mammalian cells has stimulated great interest in the possibility of treating human disease by gene-based therapies. The major aim of gene therapy is to effectively deliver the genetic materials into cells, genetically modifying and repairing cell functions, which may induce therapeutic healing of disease conditions. This ...

Nanogenomics for medicine: emerging strategies to overcome bottlenecks in siRNA-based therapy of human diseases
Silencing of gene expression by siRNA holds a promise both for a drug target discovery and as a therapy. Major bottlenecks of siRNA technology include 'off-target' silencing effects and problems with siRNA degradation before delivery. We propose a two-fold approach aimed at curtailing described shortcomings. First, before pre-clinical tests each siRNA shall be matched to comprehensive redundancy ...

Contribution of galactofuranose to the virulence of the opportunistic pathogen aspergillus fumigatus
The filamentous fungus Aspergillus fumigatus is responsible for a lethal disease called invasive aspergillosis that affects immunocompromised patients. This disease, like other human fungal diseases, is generally treated by compounds targeting the primary fungal cell membrane sterol. Recently, glucan synthesis inhibitors were added to the limited antifungal arsenal and encouraged the search for ...

Onchocerciasis Vaccine Research - Case Study
What is onchocerciasis? Onchocerciasis or river blindness is a human disease caused by the filarial worm Onchocerca volvulus, and it endangers approximately 120 million people each year globally. When the worms become adults, they can live for over a decade in knots ("nodules") under the skin and release millions of of smaller worms or microfilariae. Circulating microfilariae cause many clinical ...

Targeted Region Sequencing in Human Disease Studies and Clinical Care
Introduction to target region sequencing Since the introduction of Sanger sequencing in 1977, genetic sequencing has been greatly improved with costs simultaneously falling. With the ability to rapidly produce large volumes of sequencing data, next-generation sequencing (NGS) enables researchers to obtain whole genome or targeted regions of samples. Targeted region sequencing is preferred by ...

Modeling NAFLD using 3D bioprinted human liver tissue
Publication Summary: Nonalcoholic fatty liver disease (NAFLD) is a chronic condition that originates as lipid accumulation within hepatocytes (steatosis) and progresses into nonalcoholic steatohepatitis (NASH), characterized by lipid accumulation, inflammation, oxidative stress, and fibrosis. NAFLD is now recognized as the most common cause of chronic liver disease, with a prevalence of 25% ...

Mitochondrial Proteomics
Mitochondria are important organelles of eukaryotic cells and play a key role in the regulation of cellular energy metabolism, biosynthesis and cell death (including apoptosis and programmed cell necrosis). In addition, mitochondria are involved in important physiological processes such as tricarboxylic acid cycle, fatty acid and amino acid oxidation, and regulation of calcium ion homeostasis. ...

Effect of Climate Change on Lyme Disease Risk in North America
An understanding of the influence of climate change on Ixodes scapularis, the main vector of Lyme disease in North America, is a fundamental component in assessing changes in the spatial distribution of human risk for the disease. We used a climate suitability model of I. scapularis to examine the potential effects of global climate change on future Lyme disease risk in North America. A ...

Scientists Find Smart Human Antibody Neutralizes Ebola and Its Deadly Relatives
A research team's latest study shows that two human antibodies can simultaneously target two Ebola viruses: Ebola and Sudan. These two species have caused the largest and deadliest outbreaks. The new report suggests that researchers could combine these two potent antibodies to create an effective antiviral therapy. The work is published in Cell in the paper, “Asymmetric and ...

LncRNA Sequencing Helps to Find Deep Links to Disease
Long non-coding RNAs (lncRNAs) are a class of RNAs that do not code for proteins and are typically greater than 200 nucleotides in length. Studies have shown that lncRNAs are quite complex in function and play an important role in various biological processes such as development, differentiation, proliferation, metastasis, apoptosis, stem cell pluripotency, and DNA damage. Therefore, those ...

Exploring the Potential of RNA-Seq in Various Fields
What is RNA-Seq? Regulation of gene expression is fundamental to linking genotypes with phenotypes. RNAs shape complex gene expression networks, which drive biological processes. An in-depth understanding of the underlying mechanisms of how to govern these complex gene expression networks is vital for the treatment of complex diseases such as cancer. Hybridization-based microarrays are used to ...

Human Microbiome Research Promotes Progress of Precision Medicine
A large part of bacterial, archaeal, viral, and fungal microbial taxa consists of the human microbiome. While many of these microorganisms are commensal, some are harmful to humans and many are symbiotic. Our livelihoods are strongly intertwined with the microbes we allocate our bodies with, regardless of whether their appearance is advantageous, insignificant, or harmful. Over the past few ...

Nature: Structure-based classification of tauopathies
Abnormal accumulation of misfolded tau in filaments is characteristic of many neurodegenerative diseases—precisely for this reason, these neurodegenerative diseases are collectively referred to as tauopathy. The Michel Goedert team and the Sjors Scheres team at the Molecular Biology Laboratory of the Medical Research Council in Cambridge, UK, witnessed the use of cryo-EM to dissect tau ...
