A physiologically-based quantitative systems pharmacology model for mechanistic understanding of the response to alogliptin and its application in patients with renal impairment.

J Pharmacokinet Pharmacodyn

January 2025

Department of Clinical Pharmacy and Pharmacy Administration, West China school of Pharmacy, Sichuan University, Chengdu, 610064, China.

Alogliptin is a highly selective inhibitor of dipeptidyl peptidase-4 and primarily excreted as unchanged drug in the urine, and differences in clinical outcomes in renal impairment patients increase the risk of serious adverse reactions. In this study, we developed a comprehensive physiologically-based quantitative systematic pharmacology model of the alogliptin-glucose control system to predict plasma exposure and use glucose as a clinical endpoint to prospectively understand its therapeutic outcomes with varying renal function. Our model incorporates a PBPK model for alogliptin, DPP-4 activity described by receptor occupancy theory, and the crosstalk and feedback loops for GLP-1-GIP-glucagon, insulin, and glucose.

Int J Surg

December 2024

Department of Oncology and Cancer Institute, Sichuan Academy of Medical Sciences, Sichuan Provincial People's Hospital, University of Electronic Science and Technology of China, Chengdu, China.

Background: Biological evidence has revealed antitumor effect of vitamin D, but whether it could predict the response to neoadjuvant chemotherapy (NAC) in breast cancer (BC) patients remains inconclusive. The aim was to investigate the association between pretreatment vitamin D level and response to NAC and subsequent survival outcomes in BC patients.

Materials And Methods: The authors systematically searched the Medline, Embase, Cochrane Library, and Web of Science databases and clinical trial registries to identify relevant articles from inception to 8 October 2024.

Neuronal TRPV1-CGRP axis regulates peripheral nerve regeneration through ERK/HIF-1 signaling pathway.

J Neurochem

State Key Laboratory of Oral Diseases & National Center for Stomatology & National Clinical Research Center for Oral Diseases, West China Hospital of Stomatology, Sichuan University, Chengdu, China.

Severe trauma frequently leads to nerve damage. Peripheral nerves possess a degree of regenerative ability, and actively promoting their recovery can help restore the sensory and functional capacities of tissues. The neuropeptide calcitonin gene-related peptide (CGRP) is believed to regulate the repair of injured peripheral nerves, with neuronal transient receptor potential vanilloid type 1 (TRPV1) potentially serving as a crucial upstream factor.

One-pot ligation of multiple mRNA fragments on dsDNA splint advancing regional modification and translation.

Nucleic Acids Res

January 2025

Key Laboratory of Bio-resource and Eco-environment of Ministry of Education, The College of Life Sciences, Sichuan University, 24 South Section 1, 1st Ring Road, Chengdu, Sichuan 610064, P.R. China.

Region-specific RNA modifications are crucial for advancing RNA research and therapeutics, including messenger RNA (mRNA)-based vaccines and immunotherapy. However, the predominant method, synthesizing regionally modified mRNAs with short single-stranded DNA (ssDNA) splints, encounters challenges in ligating long mRNA fragments due to the formation of RNA self-folded complex structures. To address this issue, we developed an efficient strategy using an easily obtained long double-stranded DNA (dsDNA) as a ligation splint after in situ denaturing, while parts of this dsDNA are the templates for transcribing mRNA fragments.

Metabolic reprogramming fuels cancer cell metastasis and remodels the immunosuppressive tumor microenvironment (TME). We report here that circPETH, a circular RNA (circRNA) transported via extracellular vesicles (EVs) from tumor-associated macrophages (TAMs) to hepatocellular carcinoma (HCC) cells, facilitates glycolysis and metastasis in recipient HCC cells. Mechanistically, circPETH-147aa, encoded by circPETH in an m6A-driven manner, promotes PKM2-catalyzed ALDOA-S36 phosphorylation via the MEG pocket.

EGCG-Modified Bioactive Core-Shell Fibers Modulate Oxidative Stress to Synergistically Promote Vascularized Bone Regeneration.

ACS Biomater Sci Eng

January 2025

Research Center for Nano-Biomaterials, Analytical and Testing Center, Sichuan University, Chengdu 610064, PR China.

Oxidative stress induced by reactive oxygen species (ROS) can adversely affect tissue repair, whereas endowing biomaterials with antioxidant activity can improve the in vivo microenvironment, thereby promoting angiogenesis and osteogenesis. Accordingly, this study utilized epigallocatechin-3-gallate (EGCG), a material known for its reducing properties, oxidative self-polymerization capability, and strong binding characteristics, to modify a bioactive core-shell fibrous membrane (10RP-PG). Compared to the 10RP-PG fibrous membrane, the EGCG-modified fibrous membrane (E/10RP-PG) exhibited superior hydrophilicity, excellent cell adhesion, and compatibility.

Background: The emerging incidence of pathogenic liver conditions is turning into a major concern for global health. Induction of pyroptosis in hepatocytes instigates cellular disintegration, which in turn liberates substantial quantities of pro-inflammatory intracellular substances, thereby accelerating the advancement of liver fibrosis. Consequently, directing therapeutic efforts towards inhibiting pyroptosis could potentially serve as an innovative approach in managing inflammation related chronic hepatic disorders.

State Key Laboratory of Oral Diseases, National Clinical Research Center for Oral Diseases, Department of Cariology and Endodontics, West China Hospital of Stomatology, Sichuan University, Chengdu, 610041, Sichuan, China.

Background: Multi-lineage differentiation of mesenchymal adult stem cells (m-ASCs) is crucial for tissue regeneration and accompanied with metabolism reprogramming, among which dental-pulp-derived m-ASCs has obvious advantage of easy accessibility. Stem cell fate determination and differentiation are closely related to metabolism status in cell microenvironment, which could actively interact with epigenetic modification. In recent years, glutamine-α-ketoglutarate (αKG) axis was proved to be related to aging, tumorigenesis, osteogenesis etc.

One standing challenge for Alzheimer's disease (AD) research is early diagnosis, which provides a time window for early intervention. Sharmin et al recently reported a positive association between plasma ptau181 and plasma metabolites, medium- and long-chain acylcarnitines (ACs) in both cognitively normal (CN) Aβ- and CN Aβ+ older adults, suggesting a link between initial Aβ pathology and acylcarnitine-mediated energy metabolism pathways. Consistently, ACs could classify PET-Aβ status in elderly individuals.

Article Synopsis
  • The invention of lasers and inorganic second-order nonlinear optical (NLO) crystals has revolutionized technology by enabling unique frequency conversions, essential for various applications including information transmission and industrial uses.
  • As the demand for shorter wavelengths and higher precision lasers increases, there is a pressing need for high-performance ultraviolet NLO materials, especially those with wavelengths less than 300 nm.
  • Current methods of discovering these materials are often inefficient and based on trial-and-error; therefore, a three-step strategy is proposed for a more rational design, focusing on screening new functional groups, regulating crystal structures, and optimizing synthesis to meet stringent performance criteria.
