Gene Expression News and Research

RSS

Gene Expression is the process by which a gene gets turned on in a cell to make RNA and proteins. Gene expression may be measured by looking at the RNA, or the protein made from the RNA, or what the protein does in a cell.

Sex-differential COVID-19 responses are mediated by kynurenic acid

Now, a new study by a research team from Yale University, USA, Edith Cowan University, Australia, and the University of Strathclyde, Scotland, and published on the preprint server medRxiv in September 2020 shows that kynurenic acid is the underlying factor which is responsible for these differences.

Study reveals how B cells react to SARS-CoV-2

In an exciting immunological medRxiv preprint paper, researchers from Germany and Russia analyzed adaptive immune response in severely affected patients with coronavirus disease (COVID-19). They demonstrated a protracted immune reaction characterized by egress of B lymphocytes into the blood.

Scientists explain why men are at higher risk from COVID-19

Published in the journal PLOS Biology, the study aimed to provide a better understanding of the mechanisms that drive the varying responses of the infected individuals among different patient demographics, including sex and age.

Novel markers may predict patient response to immune checkpoint inhibitors

For many individuals with different types of cancer, immune checkpoint inhibitors can effectively boost their immune system to fight their disease, but not all patients benefit from these medications.

PI3K/mTOR and topoisomerase inhibitors suggested as candidates to reduce expression of ACE2

A recent study published in the preprint server medRxiv in September 2020 shows that the already approved drug families called P13K/mTOR and topoisomerase inhibitors may be useful in reducing individual susceptibility to the virus.

Viruses play a key evolutionary role in mammals' ability to reproduce and survive

As the world scrambles to control the growing COVID-19 coronavirus pandemic, new research in Nature Structural & Molecular Biology shows viruses also play a key evolutionary role in mammals' ability to reproduce and survive.

New insights into how the brain can induce diabetes remission in rodents

In rodents with type 2 diabetes, a single surgical injection of a protein called fibroblast growth factor 1 can restore blood sugar levels to normal for weeks or months. Yet how this growth factor acts in the brain to generate this lasting benefit has been poorly understood.

Novel RNA vaccine from Arcturus Therapeutics protects mice against SARS-CoV-2

A new study published on the preprint server bioRxiv in September 2020 reports a novel RNA vaccine platform that shows robust protection against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in mice and performs much better than a conventional mRNA vaccine. This could allow single-dose immunization, allowing progress towards global vaccination.

CRISPR-based system suppresses genes related to AAV antibody production

Gene therapy generally relies on viruses, such as adeno-associated virus (AAV), to deliver genes into a cell. In the case of CRISPR-based gene therapies, molecular scissors can then snip out a defective gene, add in a missing sequence or enact a temporary change in its expression, but the body's immune response to AAV can thwart the whole endeavor.

Understanding mechanisms in prostate cancer metastases can provide treatment opportunities

An increased awareness on a molecular level of what mechanisms prostate cancer cells use to become mobile and start spreading may in the long run provide new opportunities for treatment of aggressive prostate cancer.

Underlying pathology of MIS-C in children following SARS-CoV-2 infection

Researchers at the Icahn School of Medicine at Mount Sinai, New York, have conducted a study that sheds light on the molecular underpinnings of multisystem inflammatory syndrome in children (MIS-C).

Two MDC scientists win ERC Starting Grants for pioneering research

Dr. Kathrin de la Rosa and Dr. Ilaria Piazza, who are both junior group leaders at the Max DelbruÌ-ck Center for Molecular Medicine in the Helmholtz Association, have each won European Research Council Starting Grants.

Study shows what happens in the fetal brain affected by congenital Zika syndrome

Zika virus infection during pregnancy can cause severe abnormalities in the fetus, including malformations such as microcephaly.

Number of tentacles in sea anemones is defined by amount of food consumed

Your genetic code determines that you will grow two arms and two legs. The same fate is true for all mammals. Similarly, the number of fins a fish has and the number of legs and wings an insect has are embedded in their genetic code.

Study: BIRC2 overexpression could be a key marker for immunotherapy resistance

Johns Hopkins Medicine researchers have added to evidence that a gene responsible for turning off a cell's natural "suicide" signals may also be the culprit in making breast cancer and melanoma cells resistant to therapies that use the immune system to fight cancer.

Negligible ACE2 expression in human beta-cells

Now, a new study published on the preprint server bioRxiv reports that even though the fatality rate is significantly higher in diabetics, there is no evidence that this is due to direct viral infection of pancreatic beta cells, which produce the key hormone in glucose homeostasis, namely insulin.

Study identifies a gene's previously unknown role in fertility

A new study from Washington University School of Medicine in St. Louis identifies a specific gene's previously unknown role in fertility.

'Jumping' DNA influences the differentiation, physiological functioning of neurons

The human genome contains over 4.5 million sequences of DNA called "transposable elements", these virus-like entities that "jump" around and help regulate gene expression.

Targeting a key gateway can help treat chronic pain, shows study

Something like a quarter of the world's population suffers from chronic pain at some point. As opposed to acute pain – for example, that feeling after hitting your finger with a hammer – chronic pain may not even have a clear cause, and it can linger for years or lifetimes.

Advances in Virus Epigenetics

Growing evidence shows viruses exploit epigenetic processes to control their life cycles but epigentic regulation of viral infections is not fully understood.
