Targeting NAT10 inhibits osteosarcoma progression via ATF4/ASNS-mediated asparagine biosynthesis.

Despite advances in treatment, the prognosis of patients with osteosarcoma remains unsatisfactory, and searching for potential targets is imperative. Here, we identify N4-acetylcytidine (ac4C) acetyltransferase 10 (NAT10) as a candidate therapeutic target in osteosarcoma through functional screening. NAT10 overexpression is correlated with a poor prognosis, and NAT10 knockout inhibits osteosarcoma progression.

Enhancing trainee performance in obstetric ultrasound through an artificial intelligence system: randomized controlled trial.

Objective: Performing obstetric ultrasound scans is challenging for inexperienced operators; therefore, the prenatal screening artificial intelligence system (PSAIS) software was developed to provide real-time feedback and guidance for trainees during their scanning procedures. The aim of this study was to investigate the potential benefits of utilizing such an artificial intelligence system to enhance the efficiency of obstetric ultrasound training in acquiring and interpreting standard basic views.

Methods: A prospective, single-center randomized controlled study was conducted at The First Affiliated Hospital of Sun Yat-sen University.

Long non-coding RNA SUN2-AS1 acts as a negative regulator of ISGs transcription to promote flavivirus infection.

Recent studies highlight the critical involvement of long non-coding RNAs (lncRNAs) in modulating viral replication and immune responses, yet their specific roles in flavivirus infections remain underexplored. Our study has identified lncRNA SUN2-AS1, which is significantly upregulated in response to flavivirus infection in A549, Huh7 cells, and monocyte-differentiated macrophages (MDMs). SUN2-AS1 interacts with the transcription factors NF-κB and STAT1, andits expression is induced by ZIKV RNA via the type I interferon (IFN) pathway.

Anatomical classification of advanced biliary tract cancer predicts programmed cell death protein 1 blockade efficacy.

Background: Immune checkpoint blockade (ICB)-based immunotherapy has inspired new hope for advanced biliary tract cancer (BTC) treatment; however, there are no prior studies that primarily focus on different anatomical types of unresectable BTCs reacting differently to ICB.

Methods: We retrospectively collected data on advanced BTC patients who received anti-programmed cell death protein 1 (anti-PD1) therapy from two affiliated hospitals of Sun Yat-Sen university. The effects of anti-PD1 were compared for different anatomical sites.

ADSCs encapsulated in Gelatin methacrylate substrate promotes the repair of peripheral nerve injury by SIRT6/PGC-1α pathway.

Peripheral nerve injury is a prevalent disease but the spontaneous recovery of nerve function is protracted and incomplete. Given the damaging of stem cells and fragile of intra-neural structures in the course of stem cell transplantation, our study tried to investigate whether encapsulating adipose derived mesenchymal stem cells (ADSCs) with GelMA could achieve better repair in peripheral nerve injury. PC-12 cells were cultured on the surface of GelMA encapsulating ADSCs and 3D co-culture system was constructed.

The prognostic analysis and a machine-learning based disease-specific survival state model in pulmonary large-cell neuroendocrine carcinomas.

Background: Pulmonary large-cell neuroendocrine carcinoma (PLCNEC) is a rare and highly malignant lung cancer. Due to the paucity of data from clinical studies, its clinical characteristics and treatment remain controversial. The present study explored factors influencing the prognosis and survival outcomes of patients with PLCNEC and developed a dependable prognostic model using machine learning.

Insulin-like growth factor-1 deficiency caused by hepatocellular adenoma leads to growth arrest, primary amenorrhea and metabolic syndrome: a case report and 4 years follow up.

Background: Hepatocellular adenoma (HCA) is a rare benign neoplasm, seldom ascribed as the cause of endocrine and metabolic derangement. We herein report a case of primary amenorrhea, growth arrest and metabolic syndrome. En bloc resection of the tumor normalized all the disturbances.

Serum amyloid A for predicting prognosis in patients with newly diagnosed Crohn's disease.

Objective: Serum amyloid A (SAA) was found to be positively correlated with the activity of Crohn's disease (CD); however, its prognostic value remains uncertain. Here, we examined its predictive ability in newly diagnosed CD and explored genetic association.

Methods: This retrospective cohort study included patients newly diagnosed as CD at the First Affiliated Hospital of Sun Yat-sen University between June 2010 and March 2022.

Identification of SNHG11 as a Therapeutic Target in Pulmonary Hypertension.

Pulmonary hypertension (PH) is a life-threatening condition characterized by pulmonary vascular remodeling and endothelial dysfunction. Current therapies primarily target vasoactive imbalances but often fail to address adverse vascular remodeling. Long non-coding RNA (lncRNA), which are key regulators of various cellular processes, remain underexplored in the context of PH.

Methylation-related differentially expressed genes as potential prognostic biomarkers for cervical cancer.

Aim: To discover novel methylation-related differentially expressed genes (MRDEGs) for cervical cancer, with a focus on their potential for early diagnosis and prognostic assessment.

Materials & Methods: We integrated data from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) databases. TCGA-MRDEGs were identified by analyzing differentially methylated genes (DMGs) and their correlation with gene expression.

A multicenter prospective study on the ESC algorithm for the early diagnosis of non-ST-elevation myocardial infarction.

This study aimed to determine the optimal high-sensitivity cardiac troponin I (hs-cTnI)-based algorithm for early diagnosis of non-ST-elevation myocardial infarction (NSTEMI) in Chinese patients.

LncRNA HOXA11-AS intercepts the POU2F2-mediated downregulation of SLC3A2 in osteoarthritis to suppress ferroptosis.

Background: Osteoarthritis (OA) is a prevalent ailment characterized by the gradual degradation of joints, resulting in discomfort and restricted movement. The recently proposed mechanism of ferroptosis is intricately associated with the initiation and progression of OA. Our study found that the long non-coding RNA HOXA11-AS reduces ferroptosis by increasing the expression of SLC3A2 through the transcription factor POU2F2.
