Penn State researchers develop a way to study microenvironment of breast cancer in 3D

Cancerous tumors thrive on blood, extending their roots deep into the fabric of the tissue of their host. They alter the genetics of surrounding cells and evolve to avoid the protective attacks of immune cells.

Scientists identify genetic mutation associated with exfoliation syndrome known to cause glaucoma

A team of researchers from the Agency for Science, Technology and Research's Genome Institute of Singapore and Bioprocessing Technology Institute, as well as Singapore Eye Research Institute, have identified a genetic mutation (functionally defective CYP39A1 gene) associated with exfoliation syndrome, the most common cause of glaucoma.

Researchers develop new technology to reduce high error rates in gene sequencing

Next-generation gene sequencing (NGS) technologies --in which millions of DNA molecules are simultaneously but individually analyzed-- theoretically provides researchers and clinicians the ability to noninvasively identify mutations in the blood stream.

Proteomic and transcriptomic profiling provide a full picture of aging process in the kidneys

Studying protein changes in the kidneys as we age, as well as the transcription of genes into proteins, helps provide a full picture of the age-related processes that take place in these organs, says a study in mice published today in eLife.

Unique system detects small changes in DNA structures

Small changes in the structure of DNA have been implicated in breast cancer and other diseases, but they've been extremely difficult to detect -- until now.

Four-part small-molecule cocktail can prevent cellular stress

Researchers at the National Institutes of Health (NIH) have devised a four-part small-molecule cocktail that can protect stem cells called induced pluripotent stem cells (iPSCs) from stress and maintain normal stem cell structure and function.

Rapid and sensitive SARS-CoV-2 detection from saliva using CRISPR

In a paper recently uploaded to the preprint server medRxiv by Edward Málaga Trillo et al. (April 29th, 2021), these methods are tested in combination with CRISPR-Cas detection in the field, demonstrating a sensitivity and specificity of 93.8% and 99%, respectively.

SARS-CoV-2 study in human gut organoids

Most of the major life-threatening symptoms of COVID-19 disease are associated with the host's generation of an exacerbated pro-inflammatory immune response. Many studies have correlated the intensity of the immune response with the severity of disease.

Differential NK cell activity found to contribute to SARS-CoV-2 infection resistance

The COVID-19 pandemic caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has affected millions of people worldwide and is the leading cause of mortality in Brazil in 2020 as well as early 2021. Clinical manifestations of COVID-19 disease range from no symptoms and mild flu-like symptoms to severe cases leading to hospitalization and death.

Designing effective multidrug-resistant-TB treatments based on DNA sequencing

Globally, tuberculosis is the most common bacterial infectious disease leading to death. The pathogen causing tuberculosis, Mycobacterium tuberculosis, has a number of peculiarities. One is that it is growing very slowly.

COVID-19 may not have appeared first in China, suggests new genomic study

A new study in Acta Mathematica Scientia suggests that the virus may have originated in multiple countries almost simultaneously, rather than spreading from China to the rest of the world.

Class I HLA alleles shape CD8+ T cell repertoire in SARS-CoV-2 infection

An interesting new study discusses how adaptive cellular immunity against the SARS-CoV-2 is dependent on differences in HLA-encoding genes between patients.

New gene therapy restores dystrophin protein in patients with Duchenne muscular dystrophy

UT Southwestern scientists successfully employed a new type of gene therapy to treat mice with Duchenne muscular dystrophy (DMD), uniquely utilizing CRISPR-Cas9-based tools to restore a large section of the dystrophin protein that is missing in many DMD patients.

Comprehensive "cell atlas" shows how COVID-19 can lead to organ failure and death

Scientists from several hospitals and research centers have shown what happens in individual cells of patients who died of COVID-19. In a study published in Nature, the researchers describe how infected cells from multiple organs exhibited a range of molecular and genomic changes.

Researchers identify novel SARS-CoV-2 variant with mutations in membrane protein-encoding gene

A recent study published in the Journal Emerging Microbes and Infections has highlighted the emergence of a novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant with mutations in the membrane protein-encoding gene. Two potential mutations, M:I82T and M:V70L, have been identified within the transmembrane helices, which are expected to improve viral fitness by modulating glucose uptake during replication.

Could CRISPR be used as a SARS-CoV-2 antiviral?

The potential of using this gene manipulation technology as a SARS-CoV-2 inhibitor or prophylactic is investigated in a review recently uploaded to the journal Experimental Biology and Medicine (April 25th, 2021) by Arnab Banerjee and colleagues.

Study implies a likely rise of future SARS-CoV-2 recombinants

A recent astonishing feat by US researchers revealed that recombination is not only widespread in the evolutionary history of SARS-like coronaviruses, but it can also increase fitness traits of seasonal coronaviruses. Their paper is currently available on the bioRxiv* preprint server and sets the stage for phylogenetic tracking of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
