Specificity landscapes of 40 R2R3-MYBs reveal how paralogs target different cis-elements by homodimeric binding

  •  05 March 2025
Description unavailable

Closely related transcription factor (TF) paralogs are facing the “specificity paradox”—they share similar binding motifs, but their cis-regulatory targets and physiological roles can be different. By applying high-throughput SELEX to 40 R2R3-MYB TFs, this study currently generates the largest data set illustrating the homodimeric specificities of plant TFs, while also reveals a yet unrecognized mechanism to solve the “specificity paradox”—a TF's binding specificity can change drastically upon homodimerization, and become unique across the whole family.

Gut microbiota-derived tryptophan metabolites improve total parenteral nutrition-associated infections by regulating Group 3 innate lymphoid cells

  •  26 February 2025
Description unavailable

During the use of total parenteral nutrition (TPN), the decrease in the immune function of intestinal Group 3 innate lymphoid cells (ILC3s) can lead to an increased susceptibility to infections in patients. Specifically, the use of TPN causes dysbiosis of the gut microbiota, inhibiting the secretion of IL-22 by intestinal ILC3s, which in turn results in damage to the intestinal barrier. The reduction of Lactobacillus murinus (L. murinus) is an important factor in this process. Supplementing with L. murinus can increase the expression of its metabolite, indole-3-carboxylic acid (ICA). ICA promotes the secretion of IL-22 by ILC3s by targeting Rorγt, thereby improving the intestinal barrier and reducing susceptibility to infections. This study provides an important theoretical basis for using gut microbiota to regulate immune homeostasis in the treatment of clinical diseases.

Enhancement of gut barrier integrity by a Bacillus subtilis secreted metabolite through the GADD45A-Wnt/β-catenin pathway

  •  23 February 2025
Description unavailable

Bacillus subtilis (B. subtilis) and its metabolite 2-hydroxy-4-methylpentanoic acid alleviated lipopolysaccharide (LPS)-induced intestinal epithelial barrier damage via the growth arrest and DNA damage 45A (GADD45A)-Wnt/β-catenin axis. LPS treatment led to a significant disruption of gut homeostasis. B. subtilis administration could restore gut homeostasis by alleviating inflammatory responses, increasing the abundance of beneficial bacteria, and enhancing the intestinal epithelial barrier.

Time-restricted feeding mitigates Alzheimer's disease-associated cognitive impairments via a B. pseudolongum-propionic acid-FFAR3 axis

  •  21 February 2025
Description unavailable

A 4-month of time-restricted feeding (TRF) intervention alleviated cognitive impairments in Alzheimer's disease (AD) patients, while a 3-month TRF regimen improved spatial memory, reduced amyloid-beta accumulation, and promoted microglial aggregation around plaques in AD mice. Antibiotic-induced gut microbiota depletion partly abolished TRF's benefits. Through creatively integrating gut microbiota, metabolites, and hippocampal genes, Bifidobacterium pseudolongum (B. pseudolongum) and propionic acid (PA) were identified as key contributors to TRF's cognitive effects, with supplementation of either mimicking TRF's protective benefits. Positron emission tomography imaging revealed that PA directly crossed the blood-brain barrier, and PA supplementation restored disrupted metabolism in AD mice. Knockdown of its receptor free fatty acid receptor 3 (FFAR3) diminished TRF's protective effects. A case-control study showed a negative association between PA and cognitive status, while the TRF clinical intervention linked fecal PA to cognitive status. These findings suggest PA as a potential biomarker and underscore precise TRF-based nutritional interventions as a promising strategy for managing neurodegenerative diseases.

Preconception maternal gut dysbiosis affects enteric nervous system development and disease susceptibility in offspring via the GPR41–GDNF/RET/SOX10 signaling pathway

  •  18 March 2025
Description unavailable

Preconception administration of antibiotics to female mice reduces the abundance of Limosilactobacillus reuteri in the maternal gut microbiota during pregnancy, subsequently affecting propionate levels. Decreased propionate levels downregulated the expression of Gdnf/Ret/Sox10 mediated by GPR41, leading to abnormal development of the enteric nervous system during the embryonic period. This dysplasia results in colonic dysmotility, impaired colonic epithelium, and increased susceptibility to water-avoidance stress in offspring.

HLF and PPARα axis regulates metabolic-associated fatty liver disease through extracellular vesicles derived from the intestinal microbiota

  •  07 April 2025
Description unavailable

The specific knockout of intestinal hepatic leukemia factor (HLF) improved metabolic-associated fatty liver disease (MAFLD) by inhibiting peroxisome proliferator-activated receptor alpha (PPARα) and restoring the intestinal barrier. Study of the mechanism revealed that the HLF/PPARα axis regulated gut microbiota-derived extracellular vesicles (fEVs); which, through the gut-liver cycle, suppressed hepatocyte ferroptosis and reduced hepatic steatosis. Lipidomics and functional assays identified the conjugated bile acid taurochenodeoxycholic acid (TCDCA) as the key driver of the lipid-lowering effect of fEVs. The findings offer new therapeutic strategies for MAFLD.

New insights into genome assembly at the chromosome-level of Prunus tomentosa in evolution and cold tolerance

  •  20 March 2025
Description unavailable

This study assembled a high-quality chromosome-level genome of Prunus tomentosa, offering a vital resource for elucidating its genetic architecture, evolutionary relationships, and facilitating genome-assisted breeding efforts. Multi-omics integration revealed PtIMP3 and PtMIOX1L as key factors in cold tolerance of P. tomentosa. PtIMP3 drives the conversion of glucose-6-phosphate to myo-inositol, while PtMIOX1L catalyzes myo-inositol to d-glucuronic acid. Specifically, the high expression abundance of PtIMP3 and low expression abundance of PtMIOX1L resulted in high endogenous inositol levels in P. tomentosa. The application of myo-inositol enhanced the cold tolerance of cherry rootstocks by modulating reactive oxygen species concentrations and maintaining a stable relative water content. This finding supports the superior performance of P. tomentosa in adapting to extreme low-temperatures environmental conditions. These insights advance strategies for improving cold tolerance in horticultural crops, bridging fundamental research with practical applications in developing climate-resilient crops.

Profiling chimeric RNA in prostate cancer in Chinese cohorts reveals similarities and differences compared to Western populations

  •  13 March 2025
Description unavailable

Chimeric RNAs from chromosomal rearrangements have long been validated as cancer markers and therapeutic targets for many years. Recently, trans-splicing and cis-splicing between adjacent genes are also shown to generate chimeric RNAs. They influence tumor progression by coding fusion proteins, acting as long noncoding or circular RNAs, or altering parental gene expression. Here, we analyzed chimeric RNAs from The Cancer Genome Atlas and Chinese Prostate Cancer Genome and Epigenome Atlas, identifying similarities and differences between Western and Chinese prostate cancer (PCa) cohorts. We confirmed distinct chimeric RNA expression patterns among cancer epithelial cells, cancer-associated fibroblasts, tumor-associated macrophages, and T cells. We unraveled how these chimeras impact tumor cell growth, stromal cell transformation, and intercellular communication within the microenvironment. This comprehensive study establishes a chimeric transcriptome atlas for Chinese PCa patients, highlights population-specific disparities, and presents validated chimeric RNAs with diagnostic, prognostic, and therapeutic potential.

Histamine: A key compound in red light-enhanced Fusarium verticillioides resistance in maize

  •  07 April 2025
Description unavailable

In this study, we demonstrate that red light is the most critical light component for promoting healthy maize growth during Fusarium verticillioides infection. Red light receptors PHYTOCHROME B (PHYB) and C (PHYC) play essential roles in maize defense against this pathogen. Overexpression of PHYC in maize enhances resistance to F. verticillioides. Additionally, we identified two defense-related gene networks and some metabolites that reliant on PHYCs, involving key contributors such as WRKY transcription factors and metabolites like histamine and thiamine. Notably, the application of 50 μM histamine significantly boosts resistance, particularly under high-density conditions, marking the first report of the role of histamine in disease resistance in plants.

The impact of school heavy metal exposure on children's gut microbiota: The mediating role of environmental microorganisms

  •  25 March 2025
Description unavailable

Heavy metals are toxic and harmful pollutants that can affect the school environment and the exposed children's health. This study collected dust samples and children's fecal specimens, and performed gene sequencing. We used eXtreme Gradient Boosting to determine the impact of heavy metals on environmental microorganisms and gut microbiota, while using the relative length of the quadrant and Fourth-corner analysis to explore the relationship among the three components. We found heavy metal pollution existed in the classroom environment, with lead and copper significantly affecting environmental microorganisms' community structure. Although nonsignificant associations were observed between heavy metals and gut microbiota, Fourth-corner analysis revealed the associations were significantly mediated by environmental microorganisms. Both heavy metals and microorganisms in the environment can disrupt the microbial community structure in the intestines of exposed children.
