Epithelial SLC25A20 Deficiency Drives Immunosuppressive Neutrophil Remodeling via ARG1 Palmitoylation to Promote Colorectal Cancer

open access: yesAdvanced Science, EarlyView.
SLC25A20 deficiency in tumor cells compromises mitochondrial LCFA transport, which suppresses FAO and drives compensatory release of palmitic acid‐enriched lipids into the TME. These tumor‐derived palmitic acids are taken up by TANs, promoting ZDHHC18‐catalyzed ARG1 palmitoylation.

Lactate Signal: Modulator of Cellular Energy Production and Anabolism

open access: yesAdvanced Science, EarlyView.
Compartmentalized lactate signaling provides a spatial framework for understanding how lactate‐rich states are generated, transported, sensed, and translated into biological outputs. This Review integrates extracellular, cytosolic, mitochondrial‐associated, and nuclear lactate mechanisms to explain how lactate shapes metabolic adaptation, immune ...

Mitochondrial Localization of Cx26 Promotes Colorectal Cancer Malignancy and Exposes a Fatal Vulnerability to Drug Targeting

open access: yesAdvanced Science, EarlyView.
Mitochondrial localization of Cx26 emerges as a double‐edged sword in colorectal cancer. PIMT‐mediated methylation of Cx26 promotes its mitochondrial localization and stability. Mitochondrial Cx26 then facilitates ER‐mitochondria communication and Ca2+ signaling, thereby promoting metastatic progression. Bortezomib exploits this malignant adaptation by

Determination of Gene‐Level Fitness Contributions Across the Mucin‐Utilization Network of Bacteroides thetaiotaomicron

open access: yesAdvanced Science, EarlyView.
Genome‐wide CRISPRi and RNA‐seq resolve how B. thetaiotaomicron converts host mucosal glycans into fitness. The study reveals a layered mucin‐utilization architecture in which capsular polysaccharides constrain surface access, extracellular CAZymes and peptidases show functional redundancy, and intracellular catabolic pathways create discrete metabolic

Oral Astilbin Nanogels Modulate Senescence‐Associated CD4+ T Cells and Promote Treg Induction in Aged Mice with Colitis

open access: yesAdvanced Science, EarlyView.
Fluorinated β‐glucan/pectin nanogels enable colon‐targeted oral delivery of astilbin through gastrointestinal protection, β‐glucanase‐responsive release, mucus penetration, and prolonged retention. The released astilbin attenuates senescence‐associated features of CD4+ T cells and promotes Treg responses, while the nanogel matrix modulates the gut ...

Structural Variants in the Human Genome Associated With Gut Microbiome and Blood Metabolic Traits With Potential Causal Links

open access: yesAdvanced Science, EarlyView.
Based on a multi‐omics cohort of 2002 individuals comprising high‐depth whole‐genome and metagenomic sequencing data, blood metabolites, and detailed questionnaires, we identified 138 859 high‐confidence SVs, uncovering 36 significant SV–microbiome associations and 48 SV–blood metabolite associations.

Advancing Biotherapeutic Treatment of Ulcerative Colitis Using Lipid Mesophases: Formulation Design and Preclinical Validation

open access: yesAdvanced Science, EarlyView.
Lipid mesophases provide a versatile platform for colon‐targeted delivery of biotherapeutics, protecting them from degradation while enhancing mucoadhesion and enabling localized, controlled release to the inflamed mucosa after oral or rectal administration. In a DSS‐induced colitis model, this strategy reduced disease activity, inflammatory biomarkers,

A Dual‐Delivery System Designed to Overcome EV‐Mediated Ferroptosis Resistance for Efficient Solid Tumor Therapy

open access: yesAdvanced Science, EarlyView.
(A) Establishment and characterization of the osteosarcoma‐targeted dual‐delivery nanoplatform mBAP1/siENO1@LNP‐OTP for simultaneous regulation of BAP1 and ENO1 in tumor cells. (B) After intravenous administration, mBAP1/siENO1@LNP‐OTP preferentially accumulates at tumor sites through OTP‐mediated targeting.

Comparison of guar gum from different sources for the preparation of prolonged-release or colon-specific dosage forms

open access: yesPharmaceutical Development and Technology, 2009
The aim of the present study was to compare some physicochemical properties of guar gum samples from different sources and thus to investigate the suitability of these samples for the formulation of either prolonged-release or colon-specific dosage forms. Twelve different guar gum samples from India, Pakistan and the USA were used.

Oral delayed-release system for colonic specific delivery

International Journal of Pharmaceutics, 1994
Abstract The paper describes a novel oral time-based drug release system for colonic specific delivery. The system, designed to exploit the relatively constant small intestine transit time of dosage forms, consists of drug-containing cores coated with three polymeric layers.
