Background: Pericoronary epicardial adipose tissue (EAT) is a unique visceral fat depot that surrounds the adventitia of the coronary arteries without any anatomic barrier. Clinical studies have demonstrated the association between EAT volume and increased risks for coronary artery disease (CAD). However, the cellular and molecular mechanisms underlying the association remain elusive.

Article Synopsis
  • T cells play a critical role in hypertension, with high levels of legumain (LGMN) found in these cells; however, its specific contribution to high blood pressure is not fully understood.
  • Peripheral blood samples from hypertensive patients were analyzed, and various mouse models were used to investigate the effects of knocking out or inhibiting LGMN in T cells, revealing its importance in hypertension development.
  • Results showed that increased LGMN expression in CD4+ T cells correlates with higher blood pressure and reduced regulatory T cell function, indicating that LGMN contributes to hypertension by impairing Treg differentiation and functioning, which promotes inflammation.

Background: The majority of people with diabetes are susceptible to cardiac dysfunction and heart failure, and conventional drug therapy cannot correct diabetic cardiomyopathy progression. Herein, we assessed the potential role and therapeutic value of USP28 (ubiquitin-specific protease 28) on the metabolic vulnerability of diabetic cardiomyopathy.

Methods: The type 2 diabetes mouse model was established using db/db leptin receptor-deficient mice and high-fat diet/streptozotocin-induced mice.

Immunotherapy failures can result from the highly suppressive tumour microenvironment that characterizes aggressive forms of cancer such as recurrent glioblastoma (rGBM). Here we report the results of a first-in-human phase I trial in 41 patients with rGBM who were injected with CAN-3110-an oncolytic herpes virus (oHSV). In contrast to other clinical oHSVs, CAN-3110 retains the viral neurovirulence ICP34.

Article Synopsis
  • The study assessed a deep learning model's ability to distinguish between malignant and benign breast tumors using ultrasound images from multiple hospitals.
  • It involved 45,909 images and included interpretations from both novice and experienced radiologists to evaluate the model's impact on diagnosis accuracy.
  • The findings showed high diagnostic performance with AUC scores around 0.94 and suggested that the model can enhance the accuracy and consistency of radiologists, particularly those with less experience.

Influenza is a major cause of morbidity and mortality. The protective effect of a trivalent influenza vaccine (TIV) is undetermined in military personnel. We conducted an open-label, cluster randomized trial on active-duty servicemen of Beijing, Tianjin, and Shijiazhuang, who were randomly assigned to receive either a single dose of TIV or no treatment, according to cluster randomized sampling.

Article Synopsis
  • The study focuses on the loss of retinal photoreceptors associated with ciliopathy disorders and explores the effects of a homozygous Cep250 knockout mouse model.
  • Researchers utilized various methods, including untargeted metabolomics and imaging techniques, to investigate retinal degeneration and found significant changes in the outer nuclear layer and scotopic responses.
  • Results indicated a mislocalization of proteins linked to arginine metabolism in Cep250-/- mice, suggesting that disrupted arginine pathways play a crucial role in retinal degeneration in these conditions.

Gut microbiota dysbiosis with increased pathogenic bacteria and decreased beneficial bacteria is associated with colorectal cancer (CRC) development. This study examined the effect of a newly developed probiotic formula in modulating CRC-related bacteria. We developed a probiotic formula containing three bifidobacteria (, , and ) based on the identification of bacterial species that showed significant correlations with CRC-related bacteria including (), , (), and ().

The cGAS-STING pathway is essential for immune defense against microbial pathogens and malignant cells; as such, STING is an attractive target for cancer immunotherapy. However, systemic administration of STING agonists poses safety issues while intratumoral injection is limited by tumor accessibility. Here, we generated antibody-drug conjugates (ADCs) by conjugating a STING agonist through a cleavable linker to antibodies targeting tumor cells.

Article Synopsis
  • The study investigates how nutrient starvation, particularly amino acid scarcity, influences mitochondrial dynamics, revealing that cells initiate mitochondrial fusion to avoid degradation.
  • Supplementing with certain amino acids (glutamine, leucine, and arginine) intensifies mitochondrial hyperfusion, driven by specific fusion proteins (Mfn1 and Opa1), but does not involve the MTORC1 pathway.
  • The research highlights the importance of metabolic processes, including the TCA cycle and purine biosynthesis, in the amino acid-induced hyperfusion response, suggesting a mechanism through which cells sense and respond to nutrient availability.

Article Synopsis
  • The study investigated the role of miR-96, a member of the retinal microRNA-183 cluster, in the development and function of photoreceptors in mice using CRISPR/Cas9 technology to create a mutant model.
  • Findings showed that miR-96 mutant mice experienced a delay in cone development, with mislocalization of cone-specific markers and alterations in retinal structure and function observable through ERG and OCT tests.
  • Despite the initial developmental delays, the study concluded that the absence of miR-96 does not completely halt photoreceptor development, indicating its critical role in the maturation of cones in the retina.

Etomidate is a potent and rapidly acting anesthetic with high therapeutic index (TI) and superior hemodynamic stability. However, side effect of suppressing adrenocortical function limits its clinical use. To overcome this side effect, we designed a novel etomidate analog, EL-0052, aiming to retain beneficial properties of etomidate and avoid its disadvantage of suppressing adrenocortical steroid synthesis.

Introduction: Circulating tumor cells (CTCs) and phosphatase of regenerating liver-3 (PRL-3) have been considered to be significant prognostic indicators in metastatic colorectal cancer (CRC). This study discusses the prognostic significance of mesenchymal CTCs with PRL-3 (M+ PRL-3+ CTCs) in postoperative patients with CRC.

Methods: We detected CTC subtypes (including epithelial CTCs, biphenotypic epithelial/mesenchymal CTCs, and mesenchymal CTCs) and PRL-3 in CTCs from the peripheral blood samples of 156 patients.

It was recently disclosed that CYP3A is responsible for the tertiary stereoselective oxidations of deoxycholic acid (DCA), which becomes a continuum mechanism of the host-gut microbial cometabolism of bile acids (BAs) in humans. This work aims to investigate the species differences of BA redox metabolism and clarify whether the tertiary metabolism of DCA is a conserved pathway in preclinical animals. With quantitative determination of the total unconjugated BAs in urine and fecal samples of humans, dogs, rats, and mice, it was confirmed that the tertiary oxidized metabolites of DCA were found in all tested animals, whereas DCA and its oxidized metabolites disappeared in germ-free mice.
