Despite advances in treatment, the disease remains incurable due to relapses and drug resistance. This study aims to investigate the molecular and cellular interactions within the myeloma microenvironment using single-cell RNA sequencing (scRNA-seq), Mendelian randomization (MR), and pathway analysis to uncover therapeutic targets.

Metabolic reprogramming and immunosenescence in colorectal cancer: mechanisms and therapeutic implications.

Colorectal cancer (CRC), as a highly prevalent malignant tumor worldwide, has a persistently high incidence and mortality rate. In recent years, metabolic reprogramming and immunosenescence have received extensive attention as key mechanisms for tumorigenesis, development and treatment resistance. Metabolic reprogramming not only provides energy and biosynthetic precursors for tumor cells, but also regulates immune responses by reconstructing the tumor microenvironment (TME).

Pioglitazone Ameliorates Mitochondrial Oxidative Stress and Inflammation via AMPK-Dependent Inhibition of Mitochondrial Fission in Leigh Syndrome.

Loss of function mutations of NDUFS4 resulted in Leigh syndrome, which is a progressive neurodegenerative disease and characterized by mitochondrial oxidative stress, inflammation and aberrant mitochondrial dynamics. However, there is currently no effective treatment. Here, we demonstrate that pioglitazone significantly mitigates mitochondrial reactive oxygen species (ROS) generation, lowers cyclooxygenase-2 (COX-2) mRNA levels, and rescues aberrant mitochondrial dynamics in vitro (increasing Opa-1 expression while decreasing Drp-1 expression).

The use of statins can reduce the risk of osteoarthritis and osteoporosis.

Background: Observational studies suggest that statins may be protective against osteoporosis and osteoarthritis. However, the association between statins and the risk of osteoporosis and osteoarthritis has not been fully clarified.

The Association Between the Hemoglobin Glycation Index and Cardiometabolic Diseases: A Mini-Review.

The hemoglobin glycation index (HGI) has emerged as a pivotal biomarker for evaluating long-term glycemic control, offering a more comprehensive assessment compared with conventional glycated hemoglobin (HbA1c) measurements. Elevated HGI levels are significantly correlated with the incidence of cardiometabolic diseases (CMDs). This review synthesizes current evidence on the clinical utility of the HGI across coronary artery disease (CAD), hypertension, heart failure (HF), diabetes mellitus (DM), serum uric acid (SUA) levels, and nonalcoholic fatty liver disease (NAFLD), thereby providing clinicians with an enhanced framework for precise disease stratification, therapeutic optimization, and prognostic prediction.

Investigation into the Performance of TDR and FDR Techniques for Measuring the Water Content of Biochar-Amended Loess.

This study sought to determine whether adeno-associated virus 9 (AAV9)-based gene therapy could prevent or rescue Ndufs6 deficiency-induced MCM at different disease stages. Using Ndufs6 mice to mimic MCM, cardiac dysfunction was evident at week 4 post-birth, showing reduced ejection fraction, CI activity, increased fibrosis, mitochondrial fission, and disrupted cristae.

De-succinylation-induced accumulation of TRMT10C in the nucleus plays a detrimental role in coronary microembolization via its m1A modification function.

Coronary microembolization (CME) refers to embolism in the coronary microcirculation. This study showed a reduction in succinyl transferase (CPT1A) and the succinylation substrate (succinyl-CoA) in cardiomyocytes in CME models, suppressing the succinylation of the mitochondrially localized protein TRMT10C. Suppression of succinylation promotes KPNA4 recognition of two nuclear localization signals (NLSs), KAKR and KKK(X)KVKK, in TRMT10C, which induces the transport of TRMT10C from the cytoplasm to the nucleus rather than to the mitochondria.
