Do coyotes have puppy dog eyes? New study reveals wild canines share dog"s famous expression
New research from Baylor University reveals that coyotes, like domestic dogs, have the ability to produce the famous "puppy dog eyes" expression. The study—"Coyotes can do 'puppy dog eyes' too: Comparing interspecific variation in Canis facial expr.....»»
Research provides new insights into role of mechanical forces in gene expression
The genome inside each of our cells is modeled by tension and torsion—due in part to the activity of proteins that compact, loop, wrap and untwist DNA—but scientists know little about how those forces affect the transcription of genes......»»
Exploring the role of hydrogen sulfide in the expression of iron uptake genes in E. coli
Antibiotic resistance and oxidative stress response are important biological mechanisms that help bacteria thrive, especially pathogenic bacteria like Escherichia coli. Hydrogen sulfide (H2S), a chemical messenger molecule, regulates several intracel.....»»
How a protein keeps gene clusters quiet in the cell nucleolus
In a discovery that sheds light on the complex mechanisms of gene regulation, scientists at EPFL have uncovered a critical role for the protein ZNF274 in keeping certain gene clusters turned off by anchoring them to the cell nucleolus. The study is p.....»»
How iron and metabolic constraints can aid gene discovery for photosynthesis and biofuel production
The single-cell green alga Chromochloris zofingiensis is an emerging model organism for photosynthesis and metabolism research. Previous research has shown that with the addition of glucose, Chromochloris zofingiensis shuts off photosynthesis, rerout.....»»
Naked mole-rat found to have lost infection-resistant proteins
Scientists have found that the naked mole-rat—an underground rodent that lives up to 40 years—has lost a number of CD1 functional genes. The CD1 gene family in mammals is responsible for protein synthesis that protects the body against infectious.....»»
Compact "gene scissors" enable effective genome editing, may offer future treatment of high cholesterol gene defect
CRISPR-Cas is used broadly in research and medicine to edit, insert, delete or regulate genes in organisms. TnpB is an ancestor of this well-known "gene scissors" but is much smaller and thus easier to transport into cells......»»
Study shows cholesterol enhances exosome-mediated RNA drug delivery
RNA interference (RNAi) technology has gradually become a cutting-edge technology for treating diseases such as genetic disorders and cancer due to its huge potential in gene expression regulation. However, the efficient delivery and safety of short.....»»
Team develops gene editing strategy for macroalgae Neopyropia
Neopyropia is an important economic macroalga and is one of the main macroalgae cultivation species in China, Japan, South Korea and other countries. As a critical juncture in the evolution of photosynthetic organisms, red algae to which Neopyropia b.....»»
Gene-based model predicts when Japan"s cherry buds awake from dormancy
Japan in spring is famous for its cherry blossoms, or sakura, which begin flowering in the southern region of Kyushu and blaze upwards to the remote north of Hokkaido. The most abundant cherry tree cultivar, Somei Yoshino, is the iconic symbol of spr.....»»
Silencing in action: How cells "repress" genomic remnants of ancient viruses
Researchers have identified key cellular control sites that regulate gene expression and prevent the activation of "cryptic" genomic regions, including ancient viral sequences......»»
Virtual laboratory allows scientists to simulate specific decreases in gene activity
Imagine you're looking at millions upon millions of mysterious genetic mutations. With CRISPR gene-editing technology, a select few of these mutations might have therapeutic potential. However, proving it would mean many thousands of hours of lab wor.....»»
Custom microfluidic chip design reshapes framework of spatial transcriptomics technology
Spatial transcriptomics has emerged as a powerful tool for in situ analysis of gene expression within tissues. However, current technologies still face several challenges, including high costs, limited field of view, and low throughput, significantly.....»»
