This study aimed to identify novel therapeutic targets for personalized treatment of TNBC patients by elucidating their roles in cell cycle regulation. Using weighted gene co-expression network analysis (WGCNA), we identified 83 hub genes by integrating gene expression profiles with clinical pathological grades.

Finite Element Analysis of Proximal Femoral Bionic Nail (PFBN), Proximal Femoral Nail Antirotation and InterTan for Treatment of Reverse Obliquity Intertrochanteric Fractures.

Objective: Reverse obliquity intertrochanteric fracture is an unstable type of fracture. Current guidelines recommend intramedullary fixation, but there are still complications such as screw removal, hip varus, nail withdrawal, and nail fracture. The objective of this study was to use finite element analysis to compare the biomechanical properties of the novel proximal femoral bionic nail (PFBN), proximal femoral nail antirotation (PFNA), and combined compression interlocking intramedullary nail (InterTan) in the treatment of reverse obliquity intertrochanteric fractures (AO/OTA 31-A3.

Foliar spray double-stranded RNA targeting HvIAP1 induces high larval and adult mortality in Henosepilachna vigintioctopunctata.

Background: Exogenous double-stranded RNA (dsRNA) has the potential to serve as an effective alternative to conventional chemical pesticides for the control of insect pests, because it can specifically inhibit essential gene expression in these organisms. However, identifying suitable gene targets remains a crucial step in the development of RNA interference (RNAi)-based pest control strategies.

Results: In this study, three apoptosis-related genes were selected to evaluate their potential for RNAi-induced lethality in Henosepilachna vigintioctopunctata via foliar spray dsRNAs.

Precise Identification of Native Peptides with Posttranslational Proline Hydroxylation by Nanopore.

Hydroxylation, an extensive post-translational modification on proline, is critical for the modulation of protein structures, further dominating their functions in life systems. However, current mass spectrometry-based identification, could hardly distinguish hydroxylation from neighboring oxidation due to the same mass shifts, as well as challenges posed by low abundance and exogenous oxidation during sample preparation. To address these, an engineered nanopore was designed, capable of discriminating single hydroxyl group, to achieve the identification of proline hydroxylation on individual native peptides directly in the mixture.

Polymer Ligands with Multi-Nitrogen Heterocyclic Carbenes for Enhanced Stability and Reactivity in Nanoparticle Surface Functionalization.

Nitrogen heterocyclic carbenes (NHCs) are emerging as effective substitutes for conventional thiol ligands in surface functionalization of nanoparticles (NPs), offering exceptional stability to NPs under harsh conditions. However, the highly reactive feature of NHCs limits their use in introducing chemically active groups onto the NP surface. Herein, we develop a general yet robust strategy for the efficient surface functionalization of NPs with copolymer ligands bearing various functional groups.

Transcriptomic Profiling Reveals 17β-Estradiol Treatment Represses Ubiquitin-Proteasomal Mediators in Skeletal Muscle of Ovariectomized Mice.

Background: With a decline of 17β-estradiol (E2) at menopause, E2 has been implicated in the accompanied loss of skeletal muscle mass and strength. We aimed at characterizing transcriptomic responses of skeletal muscle to E2 in female mice, testing the hypothesis that genes and pathways related to contraction and maintenance of mass are differentially expressed in ovariectomized mice with and without E2 treatment.

Methods: Soleus and tibialis anterior (TA) muscles from C57BL/6 ovariectomized mice treated with placebo (OVX) or E2 (OVX + E2) for 60 days, or from skeletal muscle-specific ERα knockout (skmERαKO) mice and wild-type littermates (skmERαWT), were used for genome-wide expression profiling, quantitative real-time PCR and immunoblotting.

The role of myocardial energy metabolism perturbations in diabetic cardiomyopathy: from the perspective of novel protein post-translational modifications.

Diabetic cardiomyopathy (DbCM), a significant chronic complication of diabetes, manifests as myocardial hypertrophy, fibrosis, and other pathological alterations that substantially impact cardiac function and elevate the risk of cardiovascular diseases and patient mortality. Myocardial energy metabolism disturbances in DbCM, encompassing glucose, fatty acid, ketone body and lactate metabolism, are crucial factors that contribute to the progression of DbCM. In recent years, novel protein post-translational modifications (PTMs) such as lactylation, β-hydroxybutyrylation, and succinylation have been demonstrated to be intimately associated with the myocardial energy metabolism process, and in conjunction with acetylation, they participate in the regulation of protein activity and gene expression activity in cardiomyocytes.

Advances in Prenatal Cell-Free DNA Screening for Dominant Monogenic Conditions: A Review of Current Progress and Future Directions in Clinical Implementation.

Prenatal cell-free DNA (cfDNA) screening has advanced significantly, extending beyond detecting aneuploidies to sub-chromosomal copy number variations. However, its application for screening dominant single-gene conditions, often caused by de novo variants, remains underutilized in the general obstetric population. This study reviews recent data and experience on prenatal cfDNA screening for dominant monogenic conditions using multiple-gene panels, highlighting its potential to enhance early detection and management of genetic disorders.

Advances in liver organoids: replicating hepatic complexity for toxicity assessment and disease modeling.

The lack of in vivo accurate human liver models hinders the investigation of liver-related diseases, injuries, and drug-related toxicity, posing challenges for both basic research and clinical applications. Traditional cellular and animal models, while widely used, have significant limitations in replicating the liver's complex responses to various stressors. Liver organoids derived from human pluripotent stem cells, adult stem cells primary cells, or tissues can mimic diverse liver cell types, major physiological functions, and architectural features.

Single-cell transcriptomics identify a novel macrophage population associated with bone invasion in pituitary neuroendocrine tumors.

Background: Bone-invasive Pituitary Neuroendocrine Tumors (BI PitNETs) epitomize an aggressive subtype of pituitary tumors characterized by bone invasion, culminating in extensive skull base bone destruction and fragmentation. This infiltration poses a significant surgical risk due to potential damage to vital nerves and arteries. However, the mechanisms underlying bone invasion caused by PitNETs remain elusive, and effective interventions for PitNET-induced bone invasion are lacking in clinical practice.
