Transcriptional control of the H-NS antagonists LeuO and RcsB-BglJ in Escherichia coli [PDF]
, 2012 The bacterial nucleoid-associated protein (NAP) H-NS is involved in the organization and compaction of the bacterial chromatin and acts as a global respressor, mainly of genes that have been acquired by horizontal gene transfer and that are related to ...

Advanced Science, EarlyView.This study demonstrates that the imbalance between osteogenic and adipogenic differentiation in senescent BMSCs, leading to excessive adipocyte accumulation, which subsequently impairs bone regeneration in aged mice. To address this pathological dysregulation, a novel energy‐supplying hydrogel system (PBR) has been developed to restore balanced ...

Engineering Immune Cell to Counteract Aging and Aging‐Associated Diseases
Advanced Science, EarlyView.This review highlights a paradigm shift in which advanced immune cell therapies, initially developed for cancer, are now being harnessed to combat aging. By engineering immune cells to selectively clear senescent cells and remodel pro‐inflammatory tissue microenvironments, these strategies offer a novel and powerful approach to delay age‐related ...

Programming Next‐Generation Synthetic Biosensors by Genetic Circuit Design
Advanced Science, EarlyView.Synthetic biology enables genetic circuit‐based biosensing to detect diverse targets, process signals, and transduce them into readable outputs or intracellular regulatory activities. However, field deployment and real‐world application of such synthetic biosensors face considerable challenges in sensitivity, specificity, speed, stability, and ...

Quinol Oxidase Encoded by \u3cem\u3ecyoABCD\u3c/em\u3e in \u3cem\u3eRhizobium etli\u3c/em\u3e CFN42 is Regulated by ActSR and is Crucial for Growth at Low pH or Low Iron Conditions [PDF]
, 2015 Rhizobium etli aerobically respires with several terminal oxidases. The quinol oxidase (Cyo) encoded by cyoABCD is needed for efficient adaptation to low oxygen conditions and cyo transcription is upregulated at low oxygen. This study sought to determine

Animal Research and One Health, EarlyView.Myo‐inositol alleviates oxidative stress in dairy cow mammary epithelial cells via the Sirt5/Nrf2 pathway to promote mitochondrial fusion. This graphical abstract was created with BioRender.com. ABSTRACT High‐yielding dairy cows are susceptible to mammary gland oxidative stress due to prolonged intensive lactation, leading to redox imbalance.

Advancing design strategies in smart stimulus‐responsive liposomes for drug release and nanomedicine
BMEMat, EarlyView.Schematic illustration of stimulus‐responsive liposomes designed for controlled drug release and nanomedicine. The innermost circle represents different liposomal structures, including unilamellar, multilamellar, and multivesicular liposomes. The middle layer illustrates the responsive phospholipid components.

Isolated sequences from the linked Myf-5 and MRF4 genes drive distinct patterns of muscle-specific expression in transgenic mice [PDF]
, 1993 In developing mouse embryos, MyoD family regulatory genes are expressed specifically in muscle precursors and mature myofibers. This pattern, taken together with the well-established ability of MyoD family members to convert a variety of cell types to ...
