1.Noncoding RNAs Regulate Cuproptosis-related Genes in Digestive Tract Tumors: Research Progress
Journal of Sun Yat-sen University(Medical Sciences) 2025;46(2):230-237
Copper is a trace element in the human body and is closely related to various signaling pathways and tumor-related biological behaviors. However, when its concentration exceeds the threshold maintained by homeostatic mechanisms, it becomes toxic and triggers cell death. Cuproptosis is a novel form of cell death, distinct from all other known cell death pathways. It occurs through the direct binding of copper to the lipoic acid components of the tricarboxylic acid cycle, leading to the aggregation of lipoic-acylated proteins and the loss of iron-sulfur cluster proteins. This triggers protein toxicity stress, ultimately resulting in cell death. Cuproptosis plays a role in the occurrence, development, and prognosis of digestive tract tumors. Noncoding RNAs (ncRNAs) such as long non-coding RNA (lncRNA), micro RNA (miRNA) and circular RNA (circRNA) directly or indirectly regulate the expression of cuproptosis-related genes (FDX1,LIPT1,LIAS,DLD,DLAT,PDHA1,PDHB,MTF1,GLS and CDKN2A) in digestive tract tumors based on ceRNA mechanism, thereby inducing copper ion accumulation, driving oxidative stress response, protein fatty acylation and ubiquitin-proteasome system, inhibiting the occurrence and development of digestive tract tumor cells. NcRNAs’ implication in the genesis of tumor cells via regulating cuproptosis-related genes provides a new insight into precision-targeted therapy for tumors. This article introduces cuproptosis, outlines the various regulatory mechanisms of cuproptosis, and provides an overview of ncRNAs and their roles. It reviews recent research on ncRNAs involved in regulating cuproptosis in digestive tract tumors such as esophageal squamous cell carcinoma, gastric cancer, hepatocellular carcinoma, colorectal carcinoma, pancreatic cancer, along with their molecular mechanisms. The article also presents clinical perspectives, aiming to provide a theoretical basis for the diagnosis and treatment of digestive tract tumors.

Myocardial fibrosis is a serious cause of heart failure and even sudden cardiac death. However, the mechanisms underlying myocardial ischemia-induced cardiac fibrosis remain unclear. Here, we identified that the expression of sterile alpha and TIR motif containing 1 (SARM1), was increased significantly in the ischemic cardiomyopathy patients, dilated cardiomyopathy patients (GSE116250) and fibrotic heart tissues of mice. Additionally, inhibition or knockdown of SARM1 can improve myocardial fibrosis and cardiac function of myocardial infarction (MI) mice. Moreover, SARM1 fibroblasts-specific knock-in mice had increased deposition of extracellular matrix and impaired cardiac function. Mechanically, elevated expression of SARM1 promotes the deposition of extracellular matrix by directly modulating P4HA1. Notably, by using the Click-iT reaction, we identified that the increased expression of ZDHHC17 promotes the palmitoylation levels of SARM1, thereby accelerating the fibrosis process. Based on the fibrosis-promoting effect of SARM1, we screened several drugs with anti-myocardial fibrosis activity. In conclusion, we have unveiled that palmitoylated SARM1 targeting P4HA1 promotes collagen deposition and myocardial fibrosis. Inhibition of SARM1 is a potential strategy for the treatment of myocardial fibrosis. The sites where SARM1 interacts with P4HA1 and the palmitoylation modification sites of SARM1 may be the active targets for anti-fibrosis drugs.

OBJECTIVES:
To investigate the mechanism through which salidroside inhibits proliferation of gastric cancer (GC) cells focusing on glucose metabolic reprogramming pathways.
METHODS:
High-throughput sequencing combined with bioinformatics analysis was employed to identify the potential targets of salidroside in human GC MGC-803 cells. Liposome-mediated transfection experiments were carried out to validate the functional and mechanistic roles of these targets. CCK-8 and colony formation assays were used to assess the effects of salidroside on GC cell viability and clonogenic ability. qRT-PCR, Western blotting, and biochemical assay kits were used to analyze the regulatory effects of salidroside on the miR-1343-3p-OGDHL/PDHB enzyme complex-pyruvate metabolic pathway in GC cells.
RESULTS:
Bioinformatics analysis suggested that the tumor-suppressive factor miR-1343-3p negatively regulated the key glycolytic enzyme gene oxoglutarate dehydrogenase-like (OGDHL) in GC cells, and OGDHL and pyruvate dehydrogenase E1 subunit beta (PDHB) were both significantly upregulated in GC tissues, which was close by correlated with reduced survival rates of GC patients. In MGC-803 cells, salidroside treatment significantly enhanced the expression level of miR-1343-3p and downregulated OGDHL expression, resulting in disruption of the stability of PDHB, reduced pyruvate oxidative decarboxylation, and consequently decreased production of acetyl-CoA and ATP.
CONCLUSIONS
Salidroside inhibits GC cell proliferation possibly by regulating the miR-1343-3p-OGDHL/PDHB enzyme complex-pyruvate metabolic pathway, which provides new insights into its anti-tumor mechanisms and suggests new strategies for targeted therapy for GC.

Objective:To investigate the clinical characteristics and management status of children with Turner syndrome (TS) in China.Methods:As a cross-sectional study, 1 089 TS patients were included in the database of the National Collaborative Alliance for the Diagnosis and Treatment of Turner Syndrome from August 2019 to November 2023. Clinical characteristics (growth development, sexual development, organ anomalies, etc.), karyotypes, auxiliary examinations, and treatments were collected and analyzed.Results:Among the 1 089 TS cases, 809 were recorded karyotypes. The karyotype distribution was as follows: 45, X in 317 cases (39.2%), X chromosome structural variants (including partial deletions of p or q arm, ring chromosome, and marker chromosome) in 89 cases (11.0%), 45, X/46, XX mosaicism in 158 cases (19.5%), mosaicism with X chromosome structural variants in 209 cases (25.8%), and presence of Y chromosome material in 36 cases (4.4%). Among the 824 TS cases, the age of diagnosis was 9.7(6.4, 12.2) years, with a height standard deviation score (HtSDS) of -3.1±1.2. Five hundred and fifty three cases underwent growth hormone (GH) stimulation test, and 352 cases (63.7%) had GH peak values <10 μg/L and 75.9% (577/760) had low IGF1 levels, with IGF1 SDS ≤-2 accounting for 38.2% (290 cases). Among 471 cases aged ≥8 years, 132 cases (28.0%) showed spontaneous sexual development (mean bone age (11.0±1.7) years), 10 cases had spontaneous menarche (mean bone age (12.0±2.2) years), and 2 cases had regular menstrual cycles. Common physical features included cubitus valgus (311 cases (28.5%)), neck webbing (188 cases (17.2%)), low posterior hairline (185 cases (17.0%)), shield chest (153 cases (14.0%)), high arched palate (127 cases (11.6%)), short fourth metacarpal (43 cases (3.9%)), and spinal abnormalities (38 cases (3.5%)). Congenital cardiovascular and urogenital anomalies occurred in 91 cases (19.4%) and 66 cases (12.0%)respectively. Abdominal ultrasound in 33 cases (7.2%) indicated fatty liver, hepatomegaly, intrahepatic bile duct stones, and splenomegaly. Among 23 cases undergoing oral glucose tolerance test (OGTT) test, 2 were diagnosed with diabetes mellitus and 4 with impaired glucose tolerance. Following diagnosis, 669 cases (80.7%) received rhGH treatment at a chronological age of (9±4) years and bone age of (8.3±3.2) years. Additionally, 112 cases (19.4%) received sex hormone replacement therapy starting at the age of (14±4) years and bone age of (12.6±1.2) years.Conclusions:The karyotypes of 45, X and mosaicism were most common in Chinese children with TS. The clinical manifestations were mainly short stature and gonadal dysplasia. However, a few TS children could be in the normal range of height, and some cases among those aged of ≥8 years old had spontaneous sexual development. Some exhibited physical features, congenital cardiovascular and urogenital anomalies, and dysfunction of the hypothalamic-pituitary-IGF1 axis. Moreover, a few of them developed impaired glucose tolerance and diabetes mellitus. Following diagnosis, most of the patients received rhGH treatment, and a few of them received sex hormone replacement therapy.

Objective:To explore the potential categories of psychological distress in spousal caregivers of stroke patients and differences in quality of life between categories, in order to provide a theoretical basis for early clinical identification and provision of individualized and targeted interventions for psychological distress in spousal caregivers of stroke patients and improvement of their quality of life.Methods:A total of 207 spouse caregivers of stroke patients hospitalized in three class 1-Grade A hospitals in Yinchuan city of Ningxia Hui Autonomous Region, who met the inclusion and exclusion criteria were selected from December 2020 to July 2021 by convenience sampling method as study subjects. The general information questionnaire, Kessler Psychological Distress Scale, and the Mos 36-Item Short from Health Survey were used for a cross-sectional survey.Results:A total of 203 spousal caregivers of stroke patients were finally investigated, 46 males and 157 females with a age of (58.65 ± 9.66) years. Psychological distress among spousal caregivers of stroke patients was categorized into 3 potential categories:no distress group (40%, 81/203), listlessness group (45%, 91/203) and helplessness and restlessness group (15%, 31/203). The psychological distress subgroup was a factor influencing the quality of life of spousal caregivers of stroke patients ( t=-10.03, P<0.05), explaining 33.0% of the variance in quality of life. Conclusions:Psychological distress in spousal caregivers of stroke patients is significantly heterogeneous. Those in the helplessness and restlessness group have the lowest quality of life and should be given focused attention and early intervention.

Objective:To explore the potential categories of resourcefulness in primary caregivers of stroke patients and analyze the differences in the characteristics of different types of caregivers, so as to provide basis for clinical construction of effective intervention plans.Methods:The 308 primary caregivers of stroke patients who met the research standards in the Department of Neurology of General Hospital of Ningxia Medical University, People′s Hospital of Ningxia Hui Autonomous Region, the First People′s Hospital of Yinchuan from December 2020 to August 2021 were selected as the research objects by convenient sampling method.The general information questionnaire, Resourcefulness Scale and Social Support Revalued Scale were used for cross-sectional investigation.Results:The resourcefulness of the primary caregivers of stroke patients were divided into 2 potential categories: low resourcefulness group (62.7%, 193/308) and high resourcefulness group (37.3%, 115/308). Uni-variate analysis showed that there were differences between potential categories: age and education level of stroke patients, whether there was long-term medication history, number of other chronic diseases, had there been any complications due to illness, age, education level and occupation of caregivers, average daily care duration, family relations, and social support ( χ2 values were -3.34 - 23.62, all P<0.05). Logistic regression analysis showed that social support and education level of caregivers were the influencing factors of caregiver resourcefulness ( P<0.05). Conclusions:The resourcefulness in the primary caregivers of stroke patients has certain characteristics. Clinically, targeted intervention measures should be formulated according to the different types of caregiver resourcefulness characteristics of caregivers and their influencing factors to improve the caregiver resourcefulness of stroke patients.
