MicroRNAs are involved in the hypothalamic leptin sensitivity

open access: yesEpigenetics, 2018
The central nervous system monitors modifications in metabolic parameters or hormone levels (leptin) and elicits adaptive responses such as food intake and glucose homeostasis regulation. Particularly, within the hypothalamus, pro-opiomelanocortin (POMC)

Most \u3cem\u3eCaenorhabditis elegans\u3c/em\u3e MicroRNAs are Individually Not Essential for Development or Viability [PDF]

open access: yes, 2007
MicroRNAs (miRNAs), a large class of short noncoding RNAs found in many plants and animals, often act to post-transcriptionally inhibit gene expression. We report the generation of deletion mutations in 87 miRNA genes in Caenorhabditis elegans, expanding

A Viral RNA Silencing Suppressor Modulates Reactive Oxygen Species Levels to Induce the Autophagic Degradation of Dicer‐Like and Argonaute‐Like Proteins

open access: yesAdvanced Science, EarlyView.
Understanding the virus‐host arms race has been a fascinating topic in virology; contributing significantly to the development of treatments and control strategies for viral diseases. CHV1 employs a sophisticated counter‐defense mechanism in its fungal host by utilizing a viral silencing suppressor to inhibit fungal FMN reductase; thereby modulating ...

NamiRNA‐Enhancer Network: The Changing Era Challenge and Chance of miRNA

open access: yesAdvanced Science, EarlyView.
MiRNAs (miRNAs) regulate diverse biological processes across species. Unlike canonical miRNA‐mediated gene repression, Nuclear Activating miRNAs (NamiRNAs) can efficiently upregulate gene expression by targeting enhancers. This review systematically summarizes recent advances in NamiRNA research, elucidates the theory of NamiRNA‐Enhancer‐mediated Gene ...

ACSS2/AATF Drives Soluble FasL‐Mediated CD8+ T Cell Apoptosis in Pancreatic Neuroendocrine Tumors

open access: yesAdvanced Science, EarlyView.
This study unveils that ACSS2‐driven acetate metabolism fuels histone pan‐acetylation in pancreatic neuroendocrine tumors (PNETs), remodeling the epigenetic landscape. The ACSS2/AATF axis transcriptionally activates soluble FasL (sFasL), which engages Fas receptors on infiltrating CD8+ T cells to trigger caspase‐8/3‐mediated apoptosis.

High Conversion Efficiency in Intrinsic High Power‐Density Mg2Sn‐GeTe Thermoelectric Generator

open access: yesAdvanced Science, EarlyView.
First Mg2Sn–GeTe thermoelectric generator achieves 9% efficiency by strategically modulating power factor–thermal conductivity interplay in intrinsically high‐power‐density system. Abstract Thermoelectric generators (TEGs) offer a sustainable solution for thermal energy harvesting, where maximizing energy output necessitates achieving both high power ...
