Researchers from the University of Tsukuba found that the FoxO-KLF15 axis regulates macronutrient metabolism in the liver in response to changes in insulin levels. This pathway promotes the conversion of protein to carbohydrate and prevents the conversion of carbohydrate to fat during fasting, but shuts down during feeding.

Researchers studied age-related changes in kidney function, combining protein analysis with gene transcription. They found that aging kidneys have increased immune cells, inflammation, and decreased mitochondrial energy production. This suggests that therapies promoting protein building or slowing breakdown may help treat age-related k...
A recent study published in Cell Reports reveals that DNA supercoiling is involved in regulating gene expression, rather than being just collateral damage. The researchers found that specific genes are massively activated in response to stimuli, and topoisomerase TOP2A plays a crucial role in this process.
Researchers identified key gene networks controlling sugar and organic acid metabolism in watermelon fruit, shedding light on its sensory quality. The study's findings have important implications for improving watermelon breeding levels in China and the development of the watermelon industry.
A preclinical study by University at Buffalo researchers has identified new genes that could be key therapeutic targets for treating Alzheimer's disease. The study found that inhibiting certain enzymes involved in abnormal gene transcription can reverse memory deficits associated with the disease.
Researchers will investigate chromatin organization within cells and how it changes over time to identify disease targets. The study aims to develop navigable maps of chromatin architecture across multiple cell types, enabling new treatments for a range of diseases.
Sperm cells activate 90% of their genes, a pattern seen in other species, to repair DNA before passing it to the next generation. This process may influence the evolution of specific genes, with unexpressed genes containing fewer DNA code errors.
Historians have picked 500 favourite cases from the astrologers' notes, providing a unique insight into health and fertility concerns, bewitchment fears, and sexual desires of thousands of lives lost to history. The transcribed casebooks offer a trap door into the arcane archive of magic and medicine.
A new study found that court reporters transcribed African American English 82.9% accurately, falling short of the 95% requirement. This discrepancy can impact trial outcomes due to potential miscomprehension by jurors and judges.
Researchers uncovered a crucial quality-control mechanism inside cells that fails when contributing to major diseases including cancers. The discovery found an enzyme called casein kinase II adds molecular tags onto Spt6, a key protein in transcription, preventing inappropriate transcription.
A study found that HIV latency differs between the gut and blood, with unique mechanisms governing transcription in each. This discovery could inform new therapies aimed at curing HIV.
A team of University of Tsukuba researchers uncovered the essential role of a specific gene region in regulating blood pressure homeostasis. By deleting certain regions of the renin gene, they found that one particular region, known as -5E, plays a crucial role in the basal expression of the gene.
Researchers found that B2 RNA interacts with EZH2 enzyme to activate heat-shock genes and induce the cellular response to stress. The study reveals a new mechanism for EZH2 to activate genes outside of its typical PRC2 complex.
A study published in PLOS Biology shows that multiple mechanisms regulate expression of genes from the single X chromosome in Drosophila testes, reflecting a balance between chromosome-wide transcriptional suppression and compensatory evolution by sex-linked genes. This balance has consequences for gene expression and genome evolution.
The study found almost double the number of differentially expressed heart and liver genes in translation compared to transcription. This discovery sheds light on the genes and regulatory pathways underlying disease, offering new avenues for research.
Researchers at the Gladstone Institutes have identified a unique change in protein structure that guides the production of RNA from DNA. The study sheds light on key aspects of transcription, including polymerase pausing and acetylation, which are crucial for precise transcription and cellular processes.
Volunteers are transcribing decades-old pen strokes from historic log entries to add to the climate record, revealing past weather and climate patterns. The project aims to provide valuable data for scientists studying the Arctic's dramatic melt back.
The study reveals that inhibitory Smads bind directly to their targets without requiring phosphorylation, constituting a crucial step in the regulation of gene transcription. This discovery sheds light on how organisms achieve balance between TGF-beta signaling pathways, critical for maintaining tissue and organism health.
A new study in Canada found that breast imaging reports generated with automatic speech recognition (ASR) systems have a higher error rate compared to conventional dictation transcription. At least one major error was found in 23% of ASR reports, while 4% of conventional reports contained errors affecting patient management.
