Elevated COMMD1 Contributes to Cardiomyocyte Copper Efflux in Chronic Myocardial Ischemia: Insights From Rhesus Monkey.

Copper deficiency, commonly observed in myocardial infarction, leads to cardiomyocyte loss and cardiac dysfunction, yet the mechanism driving copper efflux remains unclear. To further elucidate the relationship between copper transporters and cardiac copper efflux during chronic myocardial ischemia, a rhesus monkey model was established by performing the permanent ligation of the left anterior descending coronary artery. A dramatic decrease in copper concentration within ischemic cardiomyocytes was observed alongside declining cardiac function.

Ultrasensitive Detection of FEN1 Activity for Cancer Diagnosis Using a CRISPR/Cas13a-Based Triple Cascade Amplification System.

Flap endonuclease 1 (FEN1) is closely associated with tumor progression and proliferation, making it a promising biomarker for cancer diagnosis. However, developing a sensitive, reliable, and user-friendly method for quantitative FEN1 detection remains technically challenging. In this study, an ultrasensitive FEN1 biosensor is established using a target-induced cleavage-ligation-transcription-activation cascade strategy (LTACas13a) to enhance the cleavage ability of CRISPR/Cas13a.

Calcium Release-Activated Calcium Modulator ORAI1-Sensitive Serine Dehydratase Regulates Fatty Acid-Induced CD4 Th17/Treg Imbalance in Dairy Cows.

High concentrations of free fatty acids (FFAs) caused by negative energy balance render the cow more prone to inflammatory diseases in part due to an imbalance in the types of immune cells and their specific functions. We previously demonstrated that ORAI calcium release-activated calcium modulator 1 (ORAI1) was associated with increased CD4 Th17 content, but the precise mechanisms remain unclear. The purpose of this study was to evaluate the efficacy of FFAs on CD4 T cell inflammatory response.

Clinical and molecular cytogenetic findings of cat eye syndrome and a 2-year-old patient with congenital aural atresia and hearing loss.

Background: Cat eye syndrome (CES) is a rare congenital disease frequently caused by a partial tetrasomy of the proximal long (q) arm of chromosome 22, due to a small supernumerary marker chromosome (sSMC). CES patients show remarkable phenotypic variability. Despite the progress of molecular cytogenetic technology, the cause of phenotypic variability and the genotype-phenotype correlations remain unknown.

Calmodulin Contributes to Lipolysis and Inflammatory Responses in Clinical Ketosis Cows through the TLR4/IKK/NF-κB Pathway.

Clinical ketosis is a detrimental metabolic disease in dairy cows, often accompanied by severe lipolysis and inflammation in adipose tissue. Our previous study suggested a 2.401-fold upregulation in the calmodulin (CaM) level in the adipose tissue of cows with clinical ketosis.

Changes in adiponectin levels of subclinical ketosis cows and their effects on steroid hormone secretion and proliferation in follicular granulosa cells.

In dairy cows, the occurrence of subclinical ketosis (SCK) is particularly high during early lactation. Previously, we documented alterations in the abundance of adiponectin (ADPN) in anestrus cows with SCK in comparison to cows in estrus. In the present study, 60 cows were divided into two groups: control (C, n = 30) and SCK (n = 30).

Activation of Wnt/β-catenin signal induces DCs to differentiate into immune tolerant regDCs in septic mice.

Background: Sepsis is a common complication among patients in intensive care units, and has a high mortality rate, with no effective therapies to date. As immunosuppression has become the research focus of sepsis, the regulatory role of dendritic cells (DCs) in the immune response to sepsis has received attention.

Objective: To investigate the role of the Wnt/β-catenin signaling pathway in inducing the differentiation of splenic DCs in mice with sepsis caused by cecal ligation and puncture (CLP).

Fluorescence molecular tomography based on an online maximum a posteriori estimation algorithm.

Fluorescence molecular tomography (FMT) is a non-invasive, radiation-free, and highly sensitive optical molecular imaging technique for early tumor detection. However, inadequate measurement information along with significant scattering of near-infrared light within the tissue leads to high ill-posedness in the inverse problem of FMT. To improve the quality and efficiency of FMT reconstruction, we build a reconstruction model based on log-sum regularization and introduce an online maximum a posteriori estimation (OPE) algorithm to solve the non-convex optimization problem.

Discovery of an immunosuppressive functional metabolite from the insect-derived endophytic Aspergillus taichungensis SMU01.

Three p-terphenyl metabolites (1-3), three indole-diterpenoids (4-6), an herbicide sesquiterpene (7), a flavonoid (8), and five other small molecules containing nitrogen (9-13) were isolated from the medicinal insect (Periplaneta americana)-derived endophytic Aspergillus taichungensis SMU01. Their chemical structures were elucidated on the basis of spectroscopic data and quantum chemical computational methods. Biological activity of these isolates in the differentiation of mouse CD4 T cell subsets was evaluated.

Metastasis patterns and prognosis in young gastric cancer patients: A propensity score‑matched SEER database analysis.

Background: Whether young patients with metastatic gastric cancer (GC) had distinct metastasis patterns and survival outcomes from older patients remains controversial. The aim of the present study was to explore the metastasis patterns and prognostic factors in young patients and evaluate the survival outcome in comparison to their older counterparts.

Background: Doxorubicin (Dox) is a clinical first-line broad-spectrum anticancer agent. A dose-dependent cardiotoxic and myelosuppressive response limits the clinical use of Dox. Recent research indicates that Dox-induced cardiotoxicity is associated with senescent cell accumulation and that antiaging therapy can alleviate aging-related disorders.

Granzyme B + CD8 + T cells with terminal differentiated effector signature determine multiple sclerosis progression.

Background: Multiple sclerosis (MS) leads to demyelination and neurodegeneration with autoimmune responses in central nervous system. Patients begin with a relapsing-remitting (RR) course, and more than 80% of them may advance to secondary progressive MS (SPMS), which is characteristic for the gradual decline of neurological functions without demonstrated treating method to prevent. This study aims to investigate the contribution of peripheral CD8 + T cells during the conversion from RRMS to SPMS, as well as reveal potential diagnostic signature in distinguishing SPMS.
