Extracellular RNA communication: A decade of NIH common fund support illuminates exRNA biology.

The discovery that extracellular RNAs (exRNA) can act as endocrine signalling molecules established a novel paradigm in intercellular communication. ExRNAs can be transported, both locally and systemically in virtually all body fluids. In association with an array of carrier vehicles of varying complexity, exRNA can alter target cell phenotype.

Assessment of Surgical Margin of Tongue Squamous Cell Carcinoma via Raman Mapping.

Objectives: This study introduces a novel classification approach that combines convolutional neural network (CNN) and Raman mapping to differentiate between tongue squamous cell carcinoma (TSCC) and non-tumorous tissue, as well as to identify different histological grades of TSCC.

Materials And Methods: In this study, 240 Raman mappings data from 30 tissue samples were collected from 15 patients who had undergone surgical resection for TSCC. A total of 18,000 sub-mappings extracted from Raman mappings were then used to train and test a CNN model, which extracted feature representations that were subsequently processed through a fully connected network to perform classification tasks based on the Raman mapping data.

Promoter engineering with programmable upstream activating sequences in Aspergillus Niger cell factory.

Background: Aspergillus niger is an important industrial filamentous fungus used to produce organic acids and enzymes. A wide dynamic range of promoters, particularly strong promoters, are required for fine-tuning the regulation of gene expression to balance metabolic flux and achieve the high yields of desired products. However, the limited understanding of promoter architectures and activities restricts the efficient transcription regulation of targets in strain engineering in A.

Acquired sperm hypomethylation by gestational arsenic exposure is re-established in both the paternal and maternal genomes of post-epigenetic reprogramming embryos.

Background: DNA methylation plays a crucial role in mammalian development. While methylome changes acquired in the parental genomes are believed to be erased by epigenetic reprogramming, accumulating evidence suggests that methylome changes in sperm caused by environmental factors are involved in the disease phenotypes of the offspring. These findings imply that acquired sperm methylome changes are transferred to the embryo after epigenetic reprogramming.

Behavior changes to promote preconception health: a systematic review.

Background: Preconception care is expected to prevent diseases, promote health, and improve pregnancy outcomes. Although a consensus exists on the efficacy of folic acid supplementation and preconception vaccination, evidence regarding comprehensive approaches to preconception care targeting the general population remains lacking. We aimed to identify and examine preconception care programs delivered to reproductive-aged women and men to promote behavioral change.

Zinc nanoparticles from oral supplements accumulate in renal tumours and stimulate antitumour immune responses.

A successful therapeutic outcome in the treatment of solid tumours requires efficient intratumoural drug accumulation and retention. Here we demonstrate that zinc gluconate in oral supplements assembles with plasma proteins to form ZnO nanoparticles that selectively accumulate into papillary Caki-2 renal tumours and promote the recruitment of dendritic cells and cytotoxic CD8 T cells to tumour tissues. Renal tumour targeting is mediated by the preferential binding of zinc ions to metallothionein-1X proteins, which are constitutively overexpressed in Caki-2 renal tumour cells.

G-quadruplex-forming small RNA inhibits coronavirus and influenza A virus replication.

Future pandemic threats may be caused by novel coronaviruses and influenza A viruses. Here we show that when directly added to a cell culture, 12mer guanine RNA (G12) and its phosphorothioate-linked derivatives (G12(S)), rapidly entered cytoplasm and suppressed the propagation of human coronaviruses and influenza A viruses to between 1/100 and nearly 1/1000 of normal virus infectivity without cellular toxicity and induction of innate immunity. Moreover, G12(S) alleviated the weight loss caused by coronavirus infection in mice.

The microcephaly-associated transcriptional regulator AUTS2 cooperates with Polycomb complex PRC2 to produce upper-layer neurons in mice.

AUTS2 syndrome is characterized by intellectual disability and microcephaly, and is often associated with autism spectrum disorder, but the underlying mechanisms, particularly concerning microcephaly, remain incompletely understood. Here, we analyze mice mutated for the transcriptional regulator AUTS2, which recapitulate microcephaly. Their brains exhibit reduced division of intermediate progenitor cells (IPCs), leading to fewer neurons and decreased thickness in the upper-layer cortex.

Although numerous epidemiological studies have examined schistosomiasis in Sudan, the genetic diversity of Schistosoma haematobium populations, specifically through analysis of the mtcox1 gene, remains unexplored. This study aimed to investigate the risk factors associated with urogenital schistosomiasis among school pupils in El-Fasher, Western Sudan, as well as the mtcox1 genetic diversity of human S.

Artificial intelligence-based biomarkers for treatment decisions in oncology.

The development of new therapeutic strategies such as immune checkpoint inhibitors (ICIs) and targeted therapies has increased the complexity of the treatment landscape for solid tumors. At the current rate of annual FDA approvals, the potential treatment options could increase by tenfold over the next 5 years. The cost of personalized medicine technologies limits its accessibility, thus increasing socioeconomic disparities in the treated population.

Facile Formulation of a Resveratrol-Mediated Multibond Network Hydrogel with Efficient Sustainable Antibacterial, Reactive Oxygen Species Scavenging, Pro-Angiogenesis, and Immunomodulation Activities for Accelerating Infected Wound Healing.

The management of chronic infected wounds remains a significant clinical challenge, largely due to the deficiency of optimal wound dressings with adequate mechanical strength, appropriate adhesiveness, and efficient sustainable antibacterial, reactive oxygen species (ROS) scavenging, pro-angiogenesis, and immunomodulation properties. To address such a dilemma, we employed a simple and facile strategy to utilize resveratrol (RSV) as a functional component to mediate hydrogel gelation in this study. The structure of this obtained hydrogel was supported by a multibond network, which not only endowed the resultant product with superior mechanical strength and moderate adhesiveness but also effectively prolonged the bioavailability of RSV.

Maternal circadian rhythms during pregnancy dictate metabolic plasticity in offspring.

Tissue-level oscillation is achieved by tissue-intrinsic clocks along with network-dependent signals originating from distal organs and organismal behavior. Yet, it remains unexplored whether maternal circadian rhythms during pregnancy influence fetal rhythms and impact long-term susceptibility to dietary challenges in offspring. Here, we demonstrate that circadian disruption during pregnancy decreased placental and neonatal weight yet retained transcriptional and structural maturation.
