The persistent emergence of COVID-19 variants and recurrent waves of infection worldwide underscores the urgent need for vaccines that effectively reduce viral transmission and prevent infections. Current intramuscular (IM) COVID-19 vaccines inadequately protect the upper respiratory mucosa. In response, we have developed a nonadjuvanted, interferon-armed SARS-CoV-2 fusion protein vaccine with IM priming and intranasal (IN) boost sequential immunization.

Background: Cervical cancer disparities persist among minoritized women due to infrequent screening and poor follow-up. Structural and psychosocial barriers to following up with colposcopy are problematic for minoritized women. Evidence-based interventions using patient navigation and tailored telephone counseling, including the Tailored Communication for Cervical Cancer Risk (TC3), have modestly improved colposcopy attendance.

Genistein-3'-sodium sulfonate suppresses NLRP3-mediated cell pyroptosis after cerebral ischemia.

Metab Brain Dis

January 2025

Key Laboratory of Prevention and treatment of cardiovascular and cerebrovascular diseases of Ministry of Education, Gannan Medical University, Ganzhou, 341000, China.

Cerebral ischemia-induced pyroptosis contributes to the dissemination of neuroinflammation, and Nod-like receptor protein-3 (NLRP3) inflammasome plays a key role in this process. Previous studies have indicated that Genistein-3'-sodiumsulfonate (GSS) can inhibit neuroinflammation caused by cerebral ischemia, exert cerebroprotective effects, but its specific mechanism has not been comprehensively understood. The aim of this study was to explore the effect of GSS on ischemic stroke-induced cell pyroptosis.

Tumor development often requires cellular adaptation to a unique, high metabolic state; however, the molecular mechanisms that drive such metabolic changes in TFE3-rearranged renal cell carcinoma (TFE3-RCC) remain poorly understood. TFE3-RCC, a rare subtype of RCC, is defined by the formation of chimeric proteins involving the transcription factor TFE3. In this study, we analyzed cell lines and genetically engineered mice, demonstrating that the expression of the chimeric protein PRCC-TFE3 induced a hypoxia-related signature by transcriptionally upregulating HIF1α and HIF2α.

Metabolic syndrome-related diseases frequently involve disturbances in skeletal muscle lipid metabolism. The accumulation of lipid metabolites, lipid-induced mitochondrial stress in skeletal muscle cells, as well as the inflammation of adjacent adipose tissue, are associated with the development of insulin resistance and metabolic dysfunction. Consequently, when antidiabetic medications are used to treat various chronic conditions related to hyperglycaemia, the impact on skeletal muscle lipid metabolism should not be overlooked.

Intestinal epithelial cell NCoR deficiency ameliorates obesity and metabolic syndrome.

Acta Pharm Sin B

December 2024

State Key Laboratory of Bioactive Substance and Function of Natural Medicines, Institute of Materia Medica, Chinese Academy of Medical Sciences and Peking Union Medical College, Beijing 100050, China.

Nuclear receptor corepressor (NCoR1) interacts with various nuclear receptors and regulates the anabolism and catabolism of lipids. An imbalance in lipid/energy homeostasis is also an important factor in obesity and metabolic syndrome development. In this study, we found that the deletion of NCoR1 in intestinal epithelial cells (IECs) mainly activated the nuclear receptor PPAR and attenuated metabolic syndrome by stimulating thermogenesis.

Hongqiao International Institute of Medicine, Shanghai Tongren Hospital/Faculty of Basic Medicine, Chemical Biology Division of Shanghai Universities E-Institutes, Key Laboratory of Cell Differentiation and Apoptosis of the Chinese Ministry of Education, Shanghai Jiao Tong University School of Medicine, Shanghai 200025, China.

Inducing the degradation of KRAS represents a novel strategy to combat cancers with KRAS mutation. In this study, we identify ubiquitin-specific protease 2 (USP2) as a novel deubiquitinating enzyme of KRAS in multiple myeloma (MM). Specifically, we demonstrate that gambogic acid (GA) forms a covalent bond with the cysteine 284 residue of USP2 through an allosteric pocket, inhibiting its deubiquitinating activity.

Molecular changes have a substantial impact on the onset of colorectal cancer (CRC). Complexes of HOTAIR and miRNAs disrupt several cellular functions during carcinogenesis, primarily by disrupting several carcinogenic signaling pathways. In the present study, the relationships between the serum levels of transforming growth factor-β1 (TGF-β1), sirtuin-1 (SIRT1) and E-cadherin and those of HOX transcript antisense intergenic RNA (HOTAIR) and microRNA-130a (miR-130a) in individuals with CRC were analyzed, including their correlations and diagnostic potential.

Introduction: Maternity care professionals need to guide women through an increasing number of decision-making processes during pregnancy. Professionals tend to focus more on providing information than on decision support. According to the self-determination theory (SDT), professionals could help women make their own choices by fulfilling their three basic psychological needs: autonomy, competence, and relatedness through autonomy-supportive interactions.

All-In-One Entropy-Driven DNA Nanomachine for Tumor Cell-Selective Fluorescence/SERS Dual-Mode Imaging of MicroRNA.

Anal Chem

January 2025

State Key Laboratory of Analytical Chemistry for Life Science, School of Chemistry and Chemical Engineering, Nanjing University, Nanjing 210023, PR China.

An entropy-driven catalysis (EDC) strategy is appealing for amplified bioimaging of microRNAs in living cells; yet, complex operation procedures, lacking of cell selectivity, and insufficient accuracy hamper its further applications. Here, we introduce an ingenious all-in-one entropy-driven DNA nanomachine (termed as AIO-EDN), which can be triggered by endogenous apurinic/apyrimidinic endonuclease 1 (APE1) to achieve tumor cell-selective dual-mode imaging of microRNA. Compared with the traditional EDC strategy, the integrated design of AIO-EDN achieves autocatalytic signal amplification without extra fuel strands.

Oxidation of dopamine can cause various side effects, which ultimately leads to cell death and contributes to Parkinson's disease (PD). To counteract dopamine oxidation, newly synthesized dopamine is quickly transported into vesicles via vesicular monoamine transporter 2 (VMAT2) for storage. VMAT2 expression is reduced in patients with PD, and studies have shown increased accumulation of dopamine oxidation byproducts and α-synuclein in animals with low VMAT2 expression.
