Single-nucleus transcriptomics reveals a gatekeeper role for FOXP1 in primate cardiac aging

Aging poses a major risk factor for cardiovascular diseases, the leading cause of death in the aged population. However, the cell type-specific changes underlying cardiac aging are far from being clear. Here, we performed single-nucleus RNA-sequencing analysis of left ventricles from young and aged cynomolgus monkeys to define cell composition changes and transcriptomic alterations across different cell types associated with age. We found that aged cardiomyocytes underwent a dramatic loss in cell numbers and profound fluctuations in transcriptional profiles. Via transcription regulatory network analysis, we identified FOXP1, a core transcription factor in organ development, as a key downregulated factor in aged cardiomyocytes, concomitant with the dysregulation of FOXP1 target genes associated with heart function and cardiac diseases. Consistently, the deficiency of FOXP1 led to hypertrophic and senescent phenotypes in human embryonic stem cell-derived cardiomyocytes. Altogether, our findings depict the cellular and molecular landscape of ventricular aging at the single-cell resolution, and identify drivers for primate cardiac aging and potential targets for intervention against cardiac aging and associated diseases.

Nuclear factor-Y mediates pancreatic β-cell compensation by repressing reactive oxygen species-induced apoptosis under metabolic stress / 中华医学杂志(英文版)

BACKGROUND@#Pancreatic β-cells elevate insulin production and secretion through a compensatory mechanism to override insulin resistance under metabolic stress conditions. Deficits in β-cell compensatory capacity result in hyperglycemia and type 2 diabetes (T2D). However, the mechanism in the regulation of β-cell compensative capacity remains elusive. Nuclear factor-Y (NF-Y) is critical for pancreatic islets' homeostasis under physiological conditions, but its role in β-cell compensatory response to insulin resistance in obesity is unclear.@*METHODS@#In this study, using obese ( ob/ob ) mice with an absence of NF-Y subunit A (NF-YA) in β-cells ( ob , Nf-ya βKO) as well as rat insulinoma cell line (INS1)-based models, we determined whether NF-Y-mediated apoptosis makes an essential contribution to β-cell compensation upon metabolic stress.@*RESULTS@#Obese animals had markedly augmented NF-Y expression in pancreatic islets. Deletion of β-cell Nf-ya in obese mice worsened glucose intolerance and resulted in β-cell dysfunction, which was attributable to augmented β-cell apoptosis and reactive oxygen species (ROS). Furthermore, primary pancreatic islets from Nf-ya βKO mice were sensitive to palmitate-induced β-cell apoptosis due to mitochondrial impairment and the attenuated antioxidant response, which resulted in the aggravation of phosphorylated c-Jun N-terminal kinase (JNK) and cleaved caspase-3. These detrimental effects were completely relieved by ROS scavenger. Ultimately, forced overexpression of NF-Y in INS1 β-cell line could rescue palmitate-induced β-cell apoptosis, dysfunction, and mitochondrial impairment.@*CONCLUSION@#Pancreatic NF-Y might be an essential regulator of β-cell compensation under metabolic stress.

Research progress on the bone-marrow sparing intensity-modulated radiotherapy for cervical cancer / 中华放射肿瘤学杂志

The cisplatin-based concurrent chemoradiotherapy (CCRT) has been accepted as a standard treatment for most locally advanced cervical cancer. Compared with radiation therapy alone, CCRT can increase tumor control and survival rates, whereas it also can increase the incidence of acute hematological toxicity, which results in the treatment interruption or delay, and may even affect clinical efficacy and prognosis of patients. Therefore, how to reduce the incidence and severity of acute hematological toxicity induced by CCRT is a hot spot of clinical research. Previous studies have demonstrated that the occurrence of hematological toxicity is associated with the volume and dose of irradiated pelvic bone marrow. With the development of modern radiotherapy technology, precise radiotherapy technologies, such as intensity-modulated radiotherapy (IMRT) and image-guided radiotherapy (IGRT), not only guaranteed the enough dose for tumor, but also realized the protection of normal tissues. This article will focus on the feasibility of bone marrow sparing during CCRT for cervical cancer, and summarize the research progress in recent years.

Mechanism of white matter hyperintensity involved in hemorrhagic transformation after intravenous thrombolysis / 国际脑血管病杂志

Cerebrovascular disease is a common disease that seriously endangers the health of Chinese people. White matter hyperintensities (WMHs) are the most common in elderly patients. Intravenous thrombolysis is currently the most effective drug treatment for acute ischemic stroke. Hemorrhagic transformation (HT) is the most common serious complication after intravenous thrombolysis in patients with acute ischemic stroke. The destruction of blood-brain barrier in patients of WMHs can increase the risk of HT after intravenous thrombolysis. Matrix metalloproteinases and S100B jointly participate in the destruction process of blood-brain barrier in WMHs and HT after intravenous thrombolysis. At present, the pathogenesis of WHM and HT is not completely clear, and whether mild and moderate WMHs will aggravate HT is still controversial. Nevertheless, WMHs are still the independent risk factor for HT.

Role of blood pressure on stroke-related mortality: a 45-year follow-up study in China / 中华医学杂志(英文版)

BACKGROUND@#Hypertension is associated with stroke-related mortality. However, the long-term association of blood pressure (BP) and the risk of stroke-related mortality and the influence path of BP on stroke-related death remain unknown. The current study aimed to estimate the long-term causal associations between BP and stroke-related mortality and the potential mediating and moderated mediating model of the associations.@*METHODS@#This is a 45-year follow-up cohort study and a total of 1696 subjects were enrolled in 1976 and 1081 participants died by the latest follow-up in 2020. COX proportional hazard model was used to explore the associations of stroke-related death with baseline systolic blood pressure (SBP)/diastolic blood pressure (DBP) categories and BP changes from 1976 to 1994. The mediating and moderated mediating effects were performed to detect the possible influencing path from BP to stroke-related deaths. E value was calculated in the sensitivity analysis.@*RESULTS@#Among 1696 participants, the average age was 44.38 ± 6.10 years, and 1124 were men (66.3%). After a 45-year follow-up, a total of 201 (11.9%) stroke-related deaths occurred. After the adjustment, the COX proportional hazard model showed that among the participants with SBP ≥ 160 mmHg or DBP ≥ 100 mmHg in 1976, the risk of stroke-related death increased by 217.5% (hazard ratio [HR] = 3.175, 95% confidence interval [CI]: 2.297-4.388), and the adjusted HRs were higher in male participants. Among the participants with hypertension in 1976 and 1994, the risk of stroke-related death increased by 110.4% (HR = 2.104, 95% CI: 1.632-2.713), and the adjusted HRs of the BP changes were higher in male participants. Body mass index (BMI) significantly mediated the association of SBP and stroke-related deaths and this mediating effect was moderated by gender.@*CONCLUSIONS@#In a 45-year follow-up, high BP and persistent hypertension are associated with stroke-related death, and these associations were even more pronounced in male participants. The paths of association are mediated by BMI and moderated by gender.

Association between hypertension and carotid plaque in a physical examination population: a cross-sectional study / 中华健康管理学杂志

Objective@#This study aimed to assess the association between hypertension and carotid plaque in a research population in China.@*Methods@#The subjects of this study were selected from a population undergoing physical examination at the Fourth Medical Center of PLA General Hospital in 2017. We collected information on physical examination, physiological index test, blood pressure indicators were analyzed according as continuous variables (systolic blood pressure, diastolic blood pressure, and pulse pressure) and categorical variables (hypertension and quartile of blood pressure pulse pressure). A multivariate logistic regression model was conducted to estimate the correlation between blood pressure and carotid plaque development.@*Results@#A total of 716 individuals were surveyed, including 321 men (44.8%) and 395 women (55.2%), and the prevalence of hypertension and carotid plaque were 40.9%(293 cases) and 40.4% (289 cases), respectively. The prevalence of carotid plaque was higher in individuals aged ≥60 years, diabetes mellitus, hypertension and increased waist circumference, systolic blood pressure, fasting blood glucose and glycosylated hemoglobin. The prevalence of carotid plaque increased with the increase of the quartile of blood pressure and pulse pressure (Ptrend<0.05). After adjustment for age, sex, BMI, waist circumference, and total cholesterol, triglyceride, fasting blood glucose, glycosylated hemoglobin, and hemoglobin levels, every 1 mmHg increased systolic blood pressure increases the risk of carotid plaque by 1.4% (95%CI: 1.005-1.024). Compared with the control group, the risk of carotid plaque increased by 86.8% (95%CI: 1.175-2.946) and 84.8% (95%CI: 1.098-3.110) and 119.6% (95%CI: 1.165-4.142) in the group of normal high blood pressure, grade 1 hypertension and grade 2 and grade 3 hypertension, respectively; compared with the control group, the risk of carotid plaque increased by 56.2% in the group of pulse pressure difference≥60 mmHg (95%CI: 1.049-2.326), in which the risk of carotid plaque increased by 73.3% (95%CI: 1.007-2.983) in women with pulse pressure difference≥60 mmHg (1 mmHg=0.133 kPa); in the control group with pulse pressure difference of four categories Q1 (<42 mmHg), the risk of carotid plaque increased by 92.2% (95%CI: 1.173-3.149) and 95.0% (95%CI: 1.147-3.316) in Q3 (50-61 mmHg) and Q4 (≥62 mmHg), respectively.@*Conclusion@#Increased blood pressure or pulse pressure are associated with increased prevalence of carotid plaque. Prevention of elevated blood pressure and pulse pressure might be one of the effective precautions for the prevention of carotid plaque development.
