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.

Researchers find substantial regional variation in use of genomic testing for prostate cancer

Gene-expression testing provides better estimates of cancer aggressiveness and assist in treatment decision making for men with prostate cancer.

Fruit fly study reveals the effects of microgravity on the heart

Scientists at Sanford Burnham Prebys Medical Discovery Institute have shown that fruit flies that spent several weeks on the International Space Station (ISS)—about half of their lives—experienced profound structural and biochemical changes to their hearts.

Scientists use 3D mapping techniques to unravel mystery of blood stem cells

Princess Margaret scientists have revealed how stem cells are able to generate new blood cells throughout our life by looking at vast, uncharted regions of our genetic material that hold important clues to subtle biological changes in these cells.

Regulation of fat production is abnormal in obesity, shows study

Gut hormones play an important role in regulating fat production in the body. One key hormone, released a few hours after eating, turns off fat production by regulating gene expression in the liver, but this regulation is abnormal in obesity, researchers at the University of Illinois Urbana-Champaign found in a new study.

Mother's protein found to be involved in genomic imprinting process

Mothers leave their mark on their children in many ways - and Australian researchers have discovered a protein called SMCHD1 is involved in this 'imprinting' process.

The role of micro-RNA in SARS-CoV-2 infection and COVID-19

A team of researchers based in Iran have explored the role of micro-RNA in COVID-19. Their study titled, “The emerging role of microRNAs in the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection,” was published in the latest issue of the journal International Immunopharmacology.

24 Nov 2020

Inflammatory factors that aggravate COVID-19 may come from adipose tissue

There is growing evidence that adipose tissue plays a key role in the aggravation of COVID-19. One of the theories under investigation is that fat cells (adipocytes) act as a reservoir for SARS-CoV-2 and increase viral load in obese or overweight individuals.

SARS-CoV-2 suppresses ACE2 activity in COVID-19 patients

A recent study conducted by a team of international scientists has revealed that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative pathogen of coronavirus disease 2019 (COVID-19), suppresses the expression and function of human angiotensin-converting enzyme 2 (ACE2) and induces the expression of interferon-stimulated genes at the initial phase of infection. The study is currently available on the bioRxiv* preprint server.

Specific bacterial sRNA plays key role in symbiosis between Vibrio fischeri and squid

Bacteria living symbiotically within the Hawaiian bobtail squid can direct the host squid to change its normal gene-expression program to make a more inviting home, according to a new study published in PLoS Biology by researchers at the University of Hawai'i (UH) at Mānoa School of Ocean and Earth Science and Technology (SOEST).

Triple RNA sequencing dissects gene expression of virus and fungi in infection processes

Organ and stem cell transplants are proven and frequently used methods in everyday modern clinical practice. However, even when performed regularly in specialized centers, some patients still experience a number of serious complications afterward.

Research shows sexual lineage plays crucial role in transgenerational plasticity

A new pair of papers published in the Journal of Animal Ecology has shown that sexual lineage matters for how offspring receive adaptations from parents in stickleback fish.

TB researchers uncover crucial clue that explains antibiotic resistance in bacteria

For a slow-growing microbe that multiplies infrequently, Mycobacterium tuberculosis, the pathogen that causes tuberculosis (TB) has long puzzled researchers as to how it develops resistance to antibiotics so quickly, in a matter of weeks to months.
