Study explores connection between internal biological clocks and beta cell regeneration

Certain parts of our body, such as the skin or liver, can repair themselves after a damage. Known as cell regeneration, this phenomenon describes how cells that are still functional start to proliferate to compensate for the loss.

Men and women may require different brain tumor therapy, study finds

The current study shows that the sex differences in the tumor phenotype vary with the effect of the enhancer regulatory molecule bound to Brd4 on the course of stem cell-like differentiation in male and female GBM cells. Inhibition of Brd4 by genetic and pharmacological factors also varies in males and females, both in vivo and in vitro.

Exploring the effects of smoking tobacco on COVID-19 risk

A study conducted by researchers in China has shed light on how certain tobacco compounds might prevent cells from becoming infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the agent that causes coronavirus disease 2019 (COVID-19).

Proteolytic cleavage of nucleocapsid helps SARS-CoV-2 evade host immune responses

A team of scientists of the University of Oxford reveals that the nucleocapsid protein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) undergoes autoproteolysis, and that resulting products can escape the host immune responses and facilitate viral proliferation. The study is currently available on the bioRxiv preprint server.

Researchers create p16-Cre ERT2 -tdTomato mouse model to characterize in vivo senescent cells

Cell senescence is a state of permanent cell cycle arrest that was initially defined for cells grown in cell culture. It plays a key role in age-associated organ dysfunction and age-related diseases such as cancer, but the in vivo pathogenesis is largely unclear.

Induction of acute senescence may be a necessary process in hemorrhagic shock

It's called senescence, when stressed cells can no longer divide to make new cells, and it's considered a factor in aging and in some diseases.

New optical switch to precisely control the lifespan of genetic 'copies'

A novel optical switch makes it possible to precisely control the lifespan of genetic "copies". These are used by the cell as building instructions for the production of proteins.

AI used to define the cytokine storm implicated in fatal COVID-19

A new study published on the preprint server bioRxiv* in September 2020 reports the use of artificial intelligence (AI) to identify an invariant or universal host immune response found in all viral pandemics so far. The association of this response with severe COVID-19 phenotypes indicates a new understanding of the human immune response in viral pandemics.

Diabetes leads to drastic reduction in the kidney's potential to clean itself

The kidneys often become bulky and dysfunctional in diabetes, and now scientists have found that one path to this damage dramatically reduces the kidney's ability to clean up after itself.

Study: Pleotropic drugs can have both favorable and unfavorable effects on cell growth, survival

The cover for issue 37 of Oncotarget features Figure 7, "The combination of romidepsin and KU60019 is synergistic in a xenograft model of MCL," by Scotto, et al. which reported that the antiproliferative effect induced by histone deactylase inhibitors is associated with the up-regulated expression of the cyclin-dependent kinase inhibitor p21.

SARS-CoV-2 ORF9c responsible for immune evasion and efficient infection of host

A recent study by researchers at the Sanford Burnham Prebys Medical Discovery Institute and the University of California San Francisco and published on the preprint server bioRxiv in August 2020 shows that a protein encoded by the subgenomic sequence ORF9c of SARS-CoV-2 is responsible for the low antiviral response in infected humans, enabling the successful replication of the virus in the host.

Switching off 'master regulator' may protect critical brain cells from Parkinson's-related damage

Switching off a molecular "master regulator" may protect the brain from inflammatory damage and neurodegeneration in Parkinson's disease, reports a study published today in Nature Neuroscience.

Genome analysis helps detect 568 genes that drive cancer

Analysis of the genomes of 28,000 tumors from 66 types of cancer has led to the identification of 568 cancer driver genes

IRB Barcelona team receives ERC grant to develop new drugs against fibrosis

The team led by Manuel Serrano, ICREA researcher and Head of the Cellular Plasticity and Disease Lab at IRB Barcelona, has been awarded the Proof of Concept grant by the European Research Council.

People with accelerated biological age at increased risk of COVID-19 symptom severity and mortality

Now, a new study published on the preprint server medRxiv in July 2020 discusses the explanation in terms of the biological aging markers in patients with severe disease, rather than the chronological age.

Research shows IQGAP1 as a common target in variants of triple negative breast cancer

The cover for issue 26 of Oncotarget features Figure 6, "Mislocalization of IQGAP1-BRCA1 in human TNBC tumors phenocopies the dominant mutants and the TNBC cells," by Osman, et al. and reported that IQGAP1 is a signaling scaffold implicated in TNBC, but its mechanism is unknown.

Clinically approved drugs could disrupt SARS-CoV-2 from hijacking cells

An international team of researchers has analyzed how SARS-CoV-2, the virus that causes COVID-19, hijacks the proteins in its target cells.

Researchers identify new protein complex that regulates chromosome separation

Researchers from the University of Tsukuba have identified a novel protein complex that regulates Aurora B localization to ensure that chromosomes are correctly separated during cell division

Novel treatment provides cardioprotection after heart attack in animal models

A novel treatment reduces heart damage after serious heart attacks in two animal models. Injections of two chemicals in a slow-release form significantly reduced the size of the dead heart tissue, known as the infarct, and improved the function of the left ventricle, as compared to untreated subjects.

ACE2 and pattern recognition receptor genes increase with age

A recent study by researchers in California and published on the preprint server bioRxiv* in June 2020 shows that advancing age is associated with increased expression of pattern recognition receptor (PRR) genes and ACE2 receptors, possibly accounting in part for the increased severity of the disease in older adults.
