Abstract
Autophagy-related gene (ATG) 5 regulates blood lipids, chronic inflammation, CD4+ T-cell differentiation, and neuronal death and is involved in post-stroke cognitive impairment. This study aimed to explore the correlation of serum ATG5 with CD4+ T cells and cognition impairment in stroke patients. Peripheral blood was collected from 180 stroke patients for serum ATG5 and T helper (Th) 1, Th2, Th17, and regulatory T (Treg) cell detection via enzyme-linked immunosorbent assays and flow cytometry. The Mini-Mental State Examination (MMSE) scale was completed at enrollment, year (Y)1, Y2, and Y3 in stroke patients. Serum ATG5 was also measured in 50 healthy controls (HCs). Serum ATG5 was elevated in stroke patients compared to HCs (P<0.001) and was positively correlated to Th2 cells (P=0.022), Th17 cells (P<0.001), and Th17/Treg ratio (P<0.001) in stroke patients but not correlated with Th1 cells, Th1/Th2 ratio, or Treg cells (all P>0.050). Serum ATG5 (P=0.037), Th1 cells (P=0.022), Th17 cells (P=0.002), and Th17/Treg ratio (P=0.018) were elevated in stroke patients with MMSE score-identified cognition impairment vs those without cognition impairment, whereas Th2 cells, Th1/Th2 ratio, and Treg cells were not different between them (all P>0.050). Importantly, serum ATG5 was negatively linked with MMSE score at enrollment (P=0.004), Y1 (P=0.002), Y2 (P=0.014), and Y3 (P=0.001); moreover, it was positively related to 2-year (P=0.024) and 3-year (P=0.012) MMSE score decline in stroke patients. Serum ATG5 was positively correlated with Th2 and Th17 cells and estimated cognitive function decline in stroke patients.

Abstract
Objective To investigate the impact of Pseudomonas aeruginosa(PA) infection on the function of pulmonary vascular endothelial cells,and explore the mechanism of this bacterium in exacerbating lung inflammation in mice. Methods Two hours after human lung microvascular endothelial cell(HULEC-5a) were infected with the PA strain PAO1,the mRNA levels of autophagy-related gene 5(ATG5),6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase 3(PFKFB3),and calcium adhesion protein 5(CDH5) were determined by reverse transcription real-time fluorescent quantitative PCR(RT-qPCR).The protein levels of ATG5,PFKFB3,and vascular endothelial calcium adhesion protein(VE-cadherin) were detected by immunofluorescence.After the expression of ATG5 and PFKFB3 was respectively knocked down by small interfering RNA(siRNA),RT-qPCR was employed to measure the mRNA levels of ATG5,PFKFB3,and CDH5,and immunofluorescence to detect the protein levels of PFKFB3 and VE-cadherin.In addition,the lactate assay kit was used to determine the level of lactate in the cells.After mice were infected with PAO1,lung inflammation was assessed through histopathological section staining.Confocal microscopy was employed to capture and analyze fluorescence-labeled PFKFB3 and VE-cadherin in endothelial cells. Results Compared with the control group,the HULEC-5a cells infected with PAO1 showed up-regulated mRNA and protein levels of PFKFB3(all P<0.05),down-regulated mRNA level of CDH5(P=0.023),disrupted continuity and down-regulated protein level of VE-cadherin(P<0.001),and elevated lactate level(P=0.017).Compared with PAO1-infected HULEC-5a cells,knocking down PFKFB3 led to the up-regulated mRNA level of CDH5(P=0.043),lowered lactate level(P=0.047),and restored continuity of VE-cadherin;knocking down ATG5 led to up-regulated mRNA and protein levels of PFKFB3(P=0.013 and P=0.003),elevated lactate level(P=0.015),and down-regulated mRNA level of CDH5(P=0.020) and protein level of VE-cadherin(P=0.001).The HE staining results showed obvious red blood cell leakage,inflammatory cell infiltration,alveolar septal widening,and partial detachment of vascular endothelial cells in the alveoli of PA-infected mice.Immunofluorescence staining showed up-regulated expression of PFKFB3 and decreased fluorescence signal of VE-cadherin in endothelial cells of infected mice compared with normal mice. Conclusion PA may regulate the PFKFB3 pathway via AGT5 to disrupt the function of pulmonary vascular endothelial cells,thereby exacerbating the inflammation in the lungs of mice.

Abstract
Objective Our previous study suggested cyclin-dependent kinase-like 3 (CDKL3) acts as a new oncogene in esophageal squamous cell carcinoma (ESCC) cell line TE-1. However, the molecular mechanisms and biological effects of CDKL3 in ESCC remain unknown. In the present study, we aimed to explore the clinical significance of CDKL3 in ESCC and how CDKL3 regulates the malignant behavior of ESCC. Methods ESCC samples were stained by immunohistochemical staining (IHC) and analyzed for the expression of CDKL3. The functions of CDKL3 on proliferation, apoptosis, migration, invasion, and colony formation were investigated by celigo assay, MTT assay, colony formation, caspase 3/7 activity analysis, transwell migration and invasion assay, respectively. A transplanted tumor model was established to study the functions of CDKL3 on the tumorigenesis of ESCC cells. Microarray analysis was utilized to identify the CDKL3-regulated genes in ESCC cells. Results ESCC tumor tissues possessed a significantly higher expression of CDKL3 and autophagy-related gene 5 (ATG5) than matched adjacent normal tissues. The high expressions of CDKL3 were positively associated with the tumor-node-metastasis (TNM) stage and Ki67. Upregulated ATG5 expression was positively correlated with male, advanced tumor (T) stage, and TNM stage. Kaplan-Meier analysis showed that ESCC patients with higher expression of CDKL3 or ATG5 had a shorter overall survival. The worst prognosis was recognized in patients with both high manifestations of CDKL3 and ATG5. Time-dependent receiver operating characteristic (ROC) curve was established to reveal that the combination of CDKL3, ATG5, and TNM stage–based model had better prognostic accuracy than TNM stage. Moreover, CDKL3 knockdown markedly repressed cell growth and aggressivity in vitro and in vivo. Mechanistically, ATG5 was confirmed as a downstream gene involved in the pro-oncogenic function of CDKL3. Conclusion CDKL3 can be utilized as an independent poor prognostic marker in ESCC patients. Furthermore, CDKL3 may promote tumor profession, invasion, metastasis, and prohibit tumor apoptosis partly by ATG5 activation.

Abstract
Immune-mediated quantitative and qualitative defects of hematopoietic stem/progenitor cells (HSPCs) play a vital role in the pathophysiology of acquired aplastic anemia (AA). Autophagy is closely related to T cell pathophysiology and the destiny of HSPCs, in which autophagy-related gene 5 (ATG5) is indispensably involved. We hypothesized that genetic variants of ATG5 might contribute to AA. We studied six ATG5 polymorphisms in a Chinese cohort of 176 patients with AA to compare with 157 healthy controls. A markedly decreased risk of AA in the recessive models of rs510432 and rs803360 polymorphisms (adjusted odds ratio [OR], 95% confidence interval [CI] = 0.467 [0.236-0.924], P = 0.029 for ATG5 rs510432; adjusted OR [95% CI] = 0.499 [0.255-0.975], P = 0.042 for ATG5 rs803360) was observed. Furthermore, the decreased risk was even more pronounced among nonsevere AA compared with healthy controls under recessive models (adjusted OR [95% CI] = 0.356 [0.141-0.901], P = 0.029 for ATG5 rs510432; adjusted OR [95% CI] = 0.348 [0.138-0.878], P = 0.025 for ATG5 rs803360; adjusted OR [95% CI] = 0.352 [0.139-0.891], P = 0.027 for ATG5 rs473543). Above all, rs573775 can strongly predict the occurrence of newly onset hematological event in patients with AA. Our results indicate that genetic ATG5 variants contributed to AA, which may facilitate further clarifying the underlying mechanisms of AA and making a patient-tailored medical decision.
