The Cancer Microbiome Atlas gives clearer picture of microbiota living in organs


The Cancer Microbiome Atlas gives clearer picture of microbiota living in organs
Biomedical engineers at Duke University have devised an algorithm to remove contaminated microbial genetic information from The Cancer Genome Atlas (TCGA). With a clearer picture of the microbiota living in various organs in both healthy and cancerous states, researchers will now be able to find new biomarkers of disease and better understand how numerous cancers affect the human body.
In the first study using the newly decontaminated dataset, the researchers have already discovered that normal and cancerous organ tissues have a slightly different microbiota composition, that bacteria from these diseased sites can enter the bloodstream, and that this bacterial information could help diagnose cancer and predict patient outcomes. ....

New tests may help reveal the transcriptome of SARS-CoV-2 and predict disease course

As the COVID-19 pandemic continues to infect people in their hundreds of thousands around the world, a new study describes a panel of novel tests for genomic (g) and subgenomic (sg) mRNAs generated by SARS-CoV-2. Most assays in use at present are either qualitative or semi-quantitative, and cannot evaluate the transcription molecules in detail. ....

Could intranasal SARS-CoV-2 vaccines be a practical alternative to intramuscular shots?


Could intranasal SARS-CoV-2 vaccines be a practical alternative to intramuscular shots?
The unchecked advance of the coronavirus disease 2019 (COVID-19) has made it a top public health priority to produce a vaccine capable of inducing a safe and powerful protective response against its causative pathogen: severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). An encouraging new preprint, that appeared on the
bioRxiv server shows the immunogenicity, safety, and protective efficacy, of a Newcastle disease virus (NDV)-based intranasal vector vaccine in animal studies.
A host of candidate vaccines being developed against SARS-CoV-2 use viral vector platforms to present the SARS-CoV-2 spike antigen to the host immune system. Many have used the intramuscular route (i.e., ‘jabs’ or ‘shots’), but the intranasal route allows the development of local or mucosal immunity as well as systemic immunity against the virus. This will allow protection against not just s ....

Daily circadian cycles may impact our ability to fight disease


Daily circadian cycles may impact our ability to fight disease
An analysis of an exhaustive dataset on cells essential to the mammalian immune system shows that our ability to fight disease may rely more heavily on daily circadian cycles than previously assumed.
Malfunctions in circadian rhythms, the process that keeps our bodies in tune with the day/night cycles, are increasingly associated with diabetes, cancer, Alzheimer s, and many other diseases. An investigation published today in
Genome Research shows that the activity of macrophages -; cells within us that seek and destroy intruders like bacteria -; may time daily changes in their responses to pathogens and stress through the circadian control of metabolism. ....
