Study identifies immune profile of people with severe COVID-19

A team of researchers at Georgetown University Medical Center, USA, investigated how SARS-CoV-2 affects the immune system’s response during and after infection and contributes to the severity of COVID-19.

Disrupting cancer cell cycle with two commercially available inhibitors causes tumor cell death

With two commercially available inhibitors, the cell cycle of the cancer cells in the childhood tumor neuroblastoma can be disrupted at a key point causing tumor cell death.

A brain enzyme plays an important role in waking up neural stem cells

Researchers studying an enzyme in fruit fly larvae have found that it plays an important role in waking up brain stem cells from their dormant 'quiescent' state, enabling them to proliferate and generate new neurons.

A known tumor suppressor gene plays role in stress protection of adult progenitor cells

Adult progenitor cells are present in the Drosophila fly as early as its larvae stage. These cells are the only ones that are maintained throughout development and they are responsible for giving rise to adult tissues and organs.

GLS1 inhibitor selectively eliminates senescent cells, ameliorates age-associated disorders

Senescent cells accumulate in organs during aging, promote tissue dysfunction, and cause numerous aging-related diseases like cancer. The cells arise through a process called "cellular senescence," a permanent cell cycle arrest resulting from multiple stresses.

Wistar researchers discover new enzymatic function of the Epstein-Barr Virus protein

Researchers at The Wistar Institute have discovered a new enzymatic function of the Epstein-Barr Virus (EBV) protein EBNA1, a critical factor in EBV's ability to transform human cells and cause cancer.

Biomarkers can predict how genetically identical cells behave differently under stress

A set of biomarkers not traditionally associated with cell fate can accurately predict how genetically identical cells behave differently under stress, according to a UT Southwestern study.

Bruker and Evosep announce major progress in unbiased, quantitative true single-cell proteomics

Bruker Corporation and Evosep today announced major progress in high-sensitivity, quantitative true single-cell proteomics, using a modified timsTOF Pro mass spectrometer connected to an Evosep One low-flow chromatography system.

SARS-CoV-2 infected alveolar type-II lung cells show senescence

Using monoclonal antibodies against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein and senescent markers, researchers provide evidence that virus-infected lung cells acquire characteristics of cellular senescence, which also leads to expression of proinflammatory cytokines.

SARS-CoV-2 infection shown to reduce the expression of vitamin D pathway components

A recent computational study from India implicated a dysregulated vitamin D pathway in the pathobiology of the infection with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – and opened the door for experimental validation of these observations.

Research presents potential therapeutic strategy for reducing age-related diseases

Research findings by a KAIST team provide insight into the complex mechanism of cellular senescence and present a potential therapeutic strategy for reducing age-related diseases associated with the accumulation of senescent cells.

Study findings can guide personalized breast cancer therapies based on melatonin

A Brazilian study published in the Journal of Pineal Research describes a group of genes potentially regulated by the hormone melatonin in some types of cancer, especially breast cancer.

Researchers develop a promising fix to CRISPR-Cas9's unwanted changes problem

A group of researchers developed a promising fix to CRISPR-Cas9's problem with unwanted genetic changes using a method that allows them to turn off gene-editing until it reaches key cell cycle phases where more accurate repairs are likely to happen.

Researchers identify specific circular RNA that regulates neurogenesis

In a screening for a functional impact to the neuronal differentiation process, Danish researchers identified a specific circular RNA, circZNF827, which surprisingly "taps the brake" on neurogenesis.

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.
