Biotechnol Lett

December 2024

Key Laboratory of Environmental Chemistry and Ecotoxicology of Organic Pollutants of Chongqing, Ecological and Environment Monitoring Center of Chongqing, 252 Qishan Road, Chongqing, 401132, China.

Rapid diagnostic tools for Porphyromonas gingivalis (Pg), the primary microorganism responsible for the development of periodontitis, particularly those designed for chair-side applications, could provide substantial health benefits to patients. To address this issue, we developed a CRISPR/Cas12a-based rapid Pg detection method. Dual-gRNA and hairpin reporter strategies were employed to enhance CRISPR/Cas12a reaction efficiency.

Aldosterone-producing adenoma (APA) is a leading cause of primary aldosteronism (PA), a condition marked by excessive aldosterone secretion. CYP11B2, the aldosterone synthase, plays a critical role in aldosterone biosynthesis and the development of APA. Despite its significance, encoding regulatory mechanisms governing CYP11B2, particularly its degradation, remain poorly understood.

Background: Premature ovarian insufficiency (POI) is a refractory disease that severely affects female fertility. The PERK/eIF-2α/ATF4/CHOP pathway is one of the classical pathways involved in the unfolded protein response to endoplasmic reticulum stress by regulating protein synthesis and promoting apoptosis. This study aimed to investigate the functional role and mechanism of human umbilical cord mesenchymal stem cells (hUCMSCs) in the POI animal model through the PERK/eIF-2α/ATF4/CHOP pathway.

Wilms tumor (WT) is the most common kidney cancer in infants and young children. The determination of the clonality of bilateral WTs is critical to the treatment, because lineage-independent and metastatic tumors may require different treatment strategies. Here we found synchronous bilateral WT (n = 24 tumors from 12 patients) responded differently to preoperative chemotherapy.

Background: Primary pulmonary hyalinizing clear cell carcinoma (HCCC) is a rare type of primary salivary gland-type tumor of the lung. HCCC is characterized by unique pathological features, including nests, cords, or trabeculae of clear or eosinophilic tumor cells infiltrating a mucinous or hyalinized stroma. Additional analyses of this carcinoma have revealed positive epithelial markers via immunophenotyping and gene translocation through genetic testing.

Background: Signet-ring cell carcinoma (SRCC) originates from undifferentiated stem cells in the neck of glands within the lamina propria of the mucosa. Primarily affecting the stomach, SRCC can also involve the breast, pancreas, gallbladder, colon, and bladder, although these cases are rare. SRCC of the prostate is extremely rare, and diagnosing it pelvic puncture is particularly challenging.

Department of Orthodontics, Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine; College of Stomatology, National Center for Stomatology, National Clinical Research Center for Oral Diseases, Shanghai Key Laboratory of Stomatology, Shanghai Jiao Tong University, Shanghai, 200011, China.

Periodontitis, a chronic inflammatory disease, is the leading cause of tooth loss in adults and is one of the most prevalent and complex oral conditions. Oxidative stress induced by the excessive generation of reactive oxygen species (ROS) leads to periodontitis, which is closely associated with pathological processes, including mitochondrial dysfunction of periodontal cells and local immune dysregulation. However, current treatment modalities that target single pathological processes have limited long-term therapeutic effects.

Identification of VDAC1 as a cardioprotective target of Ginkgolide B.

Chem Biol Interact

December 2024

School of Bioengineering, Zhuhai Campus of Zunyi Medical University, Zhuhai, 519000, China. Electronic address:

Ginkgolide B (GB), a compound derived from Ginkgo biloba, exhibits significant cardioprotective properties, although its precise molecular target has yet to be identified. In this study, we synthesized a biotin-labeled GB probe (GB-biotin) to identify the molecular targets of GB. Our experiments demonstrated that treatment with GB or GB-biotin reduced mitochondrial injury, restored mitochondrial membrane potential, and decreased cell apoptosis in a concentration-dependent manner.

STING-Activating Polymers Boost Lymphatic Delivery of mRNA Vaccine to Potentiate Cancer Immunotherapy.

Adv Mater

December 2024

Department of Diagnostic Radiology, Yong Loo Lin School of Medicine, National University of Singapore, Singapore, 119074, Singapore.

The unprecedented success of mRNA vaccines against COVID-19 has inspired scientists to develop mRNA vaccines for cancer immunotherapy. However, using nucleoside modified mRNA as vaccine, though evading innate immune toxicity, diminishes its therapeutic efficacy for cancers. Here, we report a polyvalent stimulator of interferon genes (STING) activating polymer (termed as PD) to bolster the immunogenicity of mRNA vaccine.

Electrochemical Oxidative Cascade Cyclization of Alkenyl Alcohols with External Nucleophiles to Access Amino- and Hydroxy-Functionalized -Heterocycles.

J Org Chem

January 2025

Key Laboratory of Biocatalysis & Chiral Drug Synthesis of Guizhou Province, School of Pharmacy, Zunyi Medical University, Zunyi 563003, P. R. China.

A convenient electrochemical oxidative cascade cyclization of alkenes equipped with pendant alcohols with general nucleophiles was developed. Using readily available diarylmethanimine and carboxylic acids as nucleophilic sources, a broad range of internal alkene and terminal alkene substrates could produce RCO- and ArCN-functionalized -heterocycles in moderate to high yields without the requirement for external oxidants and metals. These resulting products can subsequently be hydrolyzed to yield valuable NH- and OH-functionalized tetrahydrofurans and tetrahydropyranes under mild conditions.
