Verteporfin‐Mediated In Situ Nanovaccine Based on Local Conventional‐Dose Hypofractionated Radiotherapy Enhances Antitumor and Immunomodulatory Effect

Advanced Science, EarlyView.
Here gelatinase‐responsive methoxypolyethyleneglycol–PVGLIG–polycaprolactone (mPEG–PVGLIG–PCL) nanoparticles’ loading verteporfin (N@VP) is developed, enhancing radiotherapy via X‐ray‐triggered singlet oxygen generation. Combined with 2 Gy (gray, a radiation dose unit) irradiation, N@VP achieves antitumor efficacy comparable to 8 Gy, and also promotes ...

Neuronal C/EBPβ Shortens the Lifespan via Inactivating NAMPT

Advanced Science, EarlyView.
Schematic diagram illustrating the mechanism of shortened lifespan in Thy 1‐C/EBPβ transgenic mice and intervention strategies. Briefly, C/EBPβ/AEP escalation in the aging brain triggers NAMPT fragmentation and NAD+ depletion. Knockout of AEP from Thy 1‐C/EBPβ Tg/Tg mice ameliorates cognitive impairments and elongates the lifespan.

Fundamental Dynamic Units: Feedforward Networks and Adjustable Gates [PDF]

arXiv, 2009
The activation/repression of a given gene is typically regulated by multiple transcription factors (TFs) that bind at the gene regulatory region and recruit RNA polymerase (RNAP). The interactions between the promoter region and TFs and between different TFs specify the dynamic responses of the gene under different physiological conditions. By choosing

Non-equilibrium dynamics of gene expression and the Jarzynski equality [PDF]

, 2007
In order to express specific genes at the right time, the transcription of genes is regulated by the presence and absence of transcription factor molecules. With transcription factor concentrations undergoing constant changes, gene transcription takes place out of equilibrium.

Mechanisms of Baicalin Alleviates Intestinal Inflammation: Role of M1 Macrophage Polarization and Lactobacillus amylovorus

Advanced Science, EarlyView.
Baicalin alleviates E. coli‐induced intestinal inflammation through dual mechanisms: direct inhibition of the TLR4/IRF/STAT signaling pathway to modulate macrophage polarization and antigen presentation, thereby regulating Th17/Treg cell differentiation; and microbiota‐mediated indirect effects via increasing Lactobacillus amylovorus abundance and ...

Nanoneedle‐Based Electroporation for Efficient Manufacturing of Human Primary Chimeric Antigen Receptor Regulatory T‐Cells

Advanced Science, EarlyView.
Low reproducibility and inefficient gene transfer hamper clinical manufacturing of chimeric antigen receptor regulatory T cells (CAR Tregs). Nanoneedle mediated electroporation generates primary human CAR Tregs under good manufacturing practice conditions with superior efficiency compared to viral transduction.

Unsupervised learning of transcriptional regulatory networks via latent tree graphical models [PDF]

arXiv, 2016
Gene expression is a readily-observed quantification of transcriptional activity and cellular state that enables the recovery of the relationships between regulators and their target genes. Reconstructing transcriptional regulatory networks from gene expression data is a problem that has attracted much attention, but previous work often makes the ...

Methionine Metabolism Dictates PCSK9 Expression and Antitumor Potency of PD‐1 Blockade in MSS Colorectal Cancer

Advanced Science, EarlyView.
xxxx. Abstract Nutrient metabolisms are vitally interrelated to cancer progression and immunotherapy. However, the mechanisms by which nutrient metabolisms interact to remodel immune surveillance within the tumor microenvironment remain largely unexplored.

Extracellular vesicles  produced by bone marrow mesenchymal stem cells overexpressing programmed death‐ligand 1 ameliorate dextran sodium sulfate‐induced ulcerative colitis in rats by regulating Th17/Treg cell balance through PTEN/PI3K/AKT/mTOR axis

Journal of Gastroenterology and Hepatology, Volume 37, Issue 12, Page 2243-2254, December 2022., 2022
Abstract Background and Aim Programmed death‐ligand 1 (PD‐L1) was involved in regulating Th17/Treg cell balance in ulcerative colitis (UC). Extracellular vesicles (EVs) from genetically modified bone marrow mesenchymal stem cells (BMSCs) can serve as a stable delivery system to overexpress PD‐L1.

Hepatic gluconeogenesis and regulatory mechanisms in lactating ruminants: A literature review

Animal Research and One Health, EarlyView.
phosphoenolpyruvate carboxy kinase, FBP1, and glucose‐6‐phosphatase are key rate‐limiting enzymes that determine the efficiency of gluconeogenesis. The main substrate for gluconeogenesis in the liver of ruminants is propionate, which provides more than 60% of the carbon source for gluconeogenesis.
