ObjectiveTo investigate the effect of circSLC8A1_005 on the fibrotic phenotype of cardiac fibroblasts and the potential mechanism involved. MethodsThe effect of adenovirus-mediated overexpression of circSLC8A1_005 on the expression of fibrosis-related genes, collagen type I alpha 1 chain (Col1a1), collagen type Ⅲ alpha 1 chain (Col3a1) and smooth muscle actin alpha 2 (Acta2), in mouse cardiac fibroblasts (mCFs) were detected. The proliferation and migration activities of mCFs were detected by EdU and wound-healing assay, respectively. Dual luciferase reporter gene assay was performed to detect the activity of potential internal ribozyme entry site (IRES) in circSLC8A1_005. CircSLC8A1_005-translated protein, SLC8A1-605aa, and its intracellular distribution was identified by Western blot assay. The effect of SLC8A1-605aa protein on transcription activity of Sod2 gene was detected by the dual luciferase reporter gene assay. RNA binding protein immunoprecipitation (RIP) was utilized to verify the interaction between SLC8A1-605aa and superoxide dismutase 2 (Sod2) mRNA. Actinomycin D treatment was used to detect the effect of SLC8A1-605aa on Sod2 mRNA stability in mCFs. ResultsAn efficient adenovirus-mediated overexpression of circSLC8A1_005 was achieved in mCFs. The enforced expression of circSLC8A1_005 suppressed proliferation and migration of mCFs, and inhibited the expression of fibrosis-related genes in mCFs. The dual luciferase reporter gene assay revealed the activities of 2 IRES in circSLC8A1_005. Results of Western blot assay showed that circSLC8A1_005 could translate protein SLC8A1-605aa with the prospected molecular weight of 70 ku, which is predominantly distributed in the nucleus. Overexpression of the circSLC8A1_005 and SLC8A1-605aa could consistently inhibit the fibrotic phenotype of mCFs. SLC8A1-605aa could up-regulate superoxide dismutase 2 (Sod2) expression, but not at the transcriptional level. RIP assay indicated that SLC8A1-605aa could specifically interact with Sod2 mRNA, and the results of actinomycin D assay showed that SLC8A1-605aa could enhance the stability of Sod2 mRNA in mCFs. ConclusionCircSLC8A1_005 inhibits the fibrotic phenotype of cardiac fibroblasts via translating SLC8A1-605aa protein, and SLC8A1-605aa may be a potential target for the treatment of myocardial fibrosis.

OBJECTIVE@#To investigate the effects of Danmu Extract Syrup (DMS) on lipopolysaccharide (LPS)-induced acute lung injury (ALI) in mice and explore the mechanism.@*METHODS@#Seventy-two male Balb/C mice were randomly divided into 6 groups according to a random number table (n=12), including control (normal saline), LPS (5 mg/kg), LPS+DMS 2.5 mL/kg, LPS+DMS 5 mL/kg, LPS+DMS 10 mL/kg, and LPS+Dexamethasone (DXM, 5 mg/kg) groups. After pretreatment with DMS and DXM, the ALI mice model was induced by LPS, and the bronchoalveolar lavage fluid (BALF) were collected to determine protein concentration, cell counts and inflammatory cytokines. The lung tissues of mice were stained with hematoxylin-eosin, and the wet/dry weight ratio (W/D) of lung tissue was calculated. The levels of tumor necrosis factor-α (TNF-α), interleukin (IL)-6 and IL-1 β in BALF of mice were detected by enzyme linked immunosorbent assay. The expression levels of Claudin-5, vascular endothelial (VE)-cadherin, vascular endothelial growth factor (VEGF), phospho-protein kinase B (p-Akt) and Akt were detected by Western blot analysis.@*RESULTS@#DMS pre-treatment significantly ameliorated lung histopathological changes. Compared with the LPS group, the W/D ratio and protein contents in BALF were obviously reduced after DMS pretreatment (P<0.05 or P<0.01). The number of cells in BALF and myeloperoxidase (MPO) activity decreased significantly after DMS pretreatment (P<0.05 or P<0.01). DMS pre-treatment decreased the levels of TNF-α, IL-6 and IL-1 β (P<0.01). Meanwhile, DMS activated the phosphoinositide 3-kinase/protein kinase B (PI3K/Akt) pathway and reversed the expressions of Claudin-5, VE-cadherin and VEGF (P<0.01).@*CONCLUSIONS@#DMS attenuated LPS-induced ALI in mice through repairing endothelial barrier. It might be a potential therapeutic drug for LPS-induced lung injury.

摘要

Elderly patients are often complicated with a variety of underlying diseases.Because aging can impact the pharmacokinetics and pharmacodynamics of drugs,and affect the immune effect,conventional anti-tumor treatment modes such as radiotherapy,chemotherapy,targeted therapy,or immunization,can not achieve optimal efficacy.Comprehensive geriatric assess-ment(CGA)is a multi-dimensional and multidisciplinary diagnostic process,which is currently regarded as the core of the as-sessment of elderly patients with cancer.By utilizing a variety of tools and scales,comprehensive assessment of elderly patients with cancer can facilitate early intervention,guide reasonable treatment,increase the chances of benefit,and improve the quality of life for some elderly patients.Moreover,CGA can help reasonably allocate medical resources and reduce the economic burden on the community.

AIM:To investigate the effect of circular RNA MYO9A-006(circMYO9A_006)on hypertrophic phenotype of cardiomyocytes and the underlying mechanism.METHODS:The effect of adenovirus-mediated overexpres-sion of circMYO9A_006 on the expression of hypertrophy-related proteins,including β-myosin heavy chain(β-MHC),skeletal muscle actin alpha 1(ACTA1)and atrial natriuretic peptide(ANP),was evaluated in neonatal mouse ventricular cardiomyocytes(NMVCs).Moreover,a neonatal rat ventricular cardiomyocyte(NRVC)model of phenylephrine(PE)-in-duced hypertrophy was established.The effect of circMYO9A_006 overexpression on NRVC size was ascertained using Phalloidin-iFluor 647 staining method.Dual-luciferase reporter assay was employed to measure the activity of potential in-ternal ribosome entry sites(IRES)in circMYO9A_006.The translation and intracellular location of the circMYO9A_006-translated protein,MYO9A-208aa,were verified using Western blot.To investigate the role of MYO9A-208aa in the ef-fect of circMYO9A_006 on the cardiomyocyte hypertrophic phenotype,we prepared and used the following adenoviruses:the recombinant circMYO9A_006-ORF adenovirus to express MYO9A-208aa,the recombinant circMYO9A_006-ATG-mut adenovirus that does not express MYO9A-208aa,the recombinant circMYO9A_006 adenovirus,and the adenovirus vector control.These were then employed to infect NRVCs.RESULTS:Successful adenovirus-mediated overexpression of circMYO9A_006 was observed in NMVCs.The increased expression of circMYO9A_006 notably reduced the expres-sion of hypertrophy-related proteins in NMVCs(P<0.01).Concurrently,overexpression of circMYO9A_006 substantially reduced the expression of hypertrophy-associated proteins and diminished the size of PE-induced NRVCs(P<0.05).Dual-luciferase reporter assay identified the activity of 2 IRES in circMYO9A_006.Western blot results indicated that circ-MYO9A_006 could produce the MYO9A-208aa protein with an anticipated molecular weight of 28 kD in NRVCs,primari-ly found in the cytoplasm.Elevated expression of both circMYO9A_006 and MYO9A-208aa consistently reduced the ex-pression of hypertrophy-associated proteins(P<0.01),and counteracted the enlarged size of PE-induced NRVCs(P<0.05).However,increased expression of circMYO9A_006-ATG-mut did not counteract the PE-induced hypertrophic phe-notype of NRVCs.CONCLUSION:circMYO9A_006 attenuates the hypertrophic phenotype of cardiomyocytes by synthe-sizing the MYO9A-208aa protein.

摘要

Prostate cancer (PCa) is one of the most common malignant tumors in the male genitourinary system. The phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt) signaling pathway is a carcinogenic pathway responsible for the migration, proliferation, and drug resistance of various cancers. In recent years, as the research on the pathogenesis of PCa is deepening, the role of the PI3K/Akt signaling pathway in the development of PCa has attracted much attention. Traditional Chinese medicine, comprehensively regulating multiple components, targets, and pathways, has shown great potential in the treatment of PCa. This article reviews the research progress of traditional Chinese medicine targeting the PI3K/Akt signaling pathway in the treatment of PCa and discusses the expression of the PI3K/Akt signaling pathway in PCa, which involves inhibiting apoptosis of PCa cells, promoting the cell cycle, invasion, and migration of PCa cells, promoting tumor tissue angiogenesis, and mediating the androgen receptor. Additionally, it summarizes the single Chinese medicines that target and regulate this pathway, including Hedyotis diffusa, Taxus chinensis, Bovisc Alculus, and Atractylodis Macrocephalae Rhizoma. The active ingredients of these Chinese medicines mainly include flavonoids, alkaloids, terpenes, polyphenols, lignans, and other compounds. The Chinese medicine compound prescriptions targeting the PI3K/Akt pathway mainly include Wenshen Sanjie prescription, Jianspi Lishi Huayu prescription, Yishen Tonglongtang, Qilan prescription, Xihuangwan, and modified Shenqi Dihuangtang. This review is expected to provide a scientific basis for deeply understanding the pathogenesis of PCa and identifying potential therapeutic targets, as well as to provide new ideas for clinical research and drug development for PCa.

摘要

Band 3 protein is an important channel protein in the erythrocyte membrane which mediates the anion transport process inside and outside the cell membrane,as well as contributes to the maintenance of erythrocyte morphology,and has important physiological functions.However,the distribution state of this protein in the primary cell membrane is not known.Cryo-scanning electron microscopy enables imaging of the surface morphology of biological samples in a near-physiological state.In order to investigate the distribution of band 3 protein on erythrocyte membranes under physiological conditions,the present study utilized 5-nm gold nanoparticles modified with the antibodies to specifically bind to the band 3 protein on human blood erythrocyte membranes and imaged them by cryo-scanning electron microscopy,to obtain distribution of band 3 protein on human blood erythrocyte membranes.The results showed that the membrane proteins on the erythrocyte membranes tended to be clustered and distributed to form ″protein islands″,and band 3 proteins were mainly distributed in these protein islands,which were tightly connected with each other to form several functional microregions to play their respective roles.

Objective To explore the value of apparent diffusion coefficient(ADC)values of magnetic resonance diffusion weighted imaging(MR-DWI)in predicting the prognosis of primary hepatocellular carcinoma(HCC)treated by radiofrequency ablation(RFA).Methods A prospective study was conducted on 178 patients with HCC.All patients were treated with RFA and followed up for 1 year after treatment.MR-DWI was performed before RFA and one month after RFA,and the changes in ADC value were calculated.These changes of the cancer in patients with different clinicopathological parameters were compared.The factors affecting the prognosis of HCC patients with RFA,and the value of ADC value changes in predicting the prognosis were analyzed.Results The changes of ADC values in patients with high alpha-fetoprotein,Barcelona clinic live cancer(BCLC)stage C,and poorly differentiated were lower than those in patients with low alpha-fetoprotein,BCLC stage B,and moderately well-differentiated(P<0.05).Six cases were lost to follow-up,and 120 of the remaining 172 patients survived.Cox regression analysis showed that the changes in ADC value,tumor stage and degree of differentiation were independent factors affecting the prognosis of HCC patients with RFA(P<0.05).Receiver operating characteristic(ROC)curve results showed that the best cut-off point,sensitivity,specificity and area under the curve(AUC)of ADC value change in predicting the prognosis of HCC patients with RFA were 0.42×10-3 mm2/s,75.00%,78.33%and 0.801.There were 16 deaths in the high change group of ADC value(>0.42)and 36 deaths in the low change group(≤0.42).The overall survival curve of the high change group of ADC value was better than that of the low change group(P<0.05).Conclusion The change in ADC value of MR-DWI sequence before and after short-term RFA treatment in HCC patients is related to the patient's pathology and prognosis,with a good predictive effect.The low change in ADC value has a higher risk of poor prognosis.

摘要

BACKGROUND:Dapagliflozin,an inhibitor of sodium-glucose cotransporter 2,can delay the progression of atherosclerosis by regulating glucose metabolism,inhibiting inflammation and improving endothelial cell function. OBJECTIVE:To study the effect of dapagliflozin on cell pyroptosis and endothelial dysfunction induced by oxidized low-density lipoprotein. METHODS:Human umbilical vein endothelial cells were divided into a control group(no intervention),a model group(treated with oxidized low-density lipoprotein for 24 hours),and a dapagliflozin group(treated with oxidized low-density lipoprotein + dapagliflozin for 24 hours).Endothelial cell proliferation activity was measured by cell counting kit-8 assay.The levels of intercellular adhesion molecule 1,vascular cell adhesion molecule 1,and monocyte chemotactic protein-1 in cell supernatant were detected using ELISA.Nitric oxide level in the cells was detected by nitrate reductase assay.The pyroptosis rate and characteristics of endothelial cells were detected by Hoechst 33342/PI fluorescence co-staining and lactate dehydrogenase release assay.The protein expression levels of NLRP3,caspase-1,GSDMD,interleukin-1β,and interleukin-18 were detected by western blot assay. RESULTS AND CONCLUSION:(1)Oxidized low-density lipoprotein could cause pyroptosis and dysfunction of endothelial cells.(2)Compared with the control group,the level of nitric oxide and cell activity were decreased(P<0.05),while lactate dehydrogenase,intercellular adhesion molecule 1,vascular cell adhesion molecule 1,and monocyte chemotactic protein-1 levels were significantly increased in the model group(P<0.05).Compared with the model group,cell activity and nitric oxide levels significantly increased(P<0.05),but lactate dehydrogenase,intercellular adhesion molecule 1,vascular cell adhesion molecule 1,and monocyte chemotactic protein-1 levels were significantly diminished in the dapagliflozin group(P<0.05).(3)Compared with the model group,cell pyroptosis rate and the protein expression of pyroptosis factor NLRP3,caspase-1,GSDMD,interleukin-18 and interleukin-1β significantly reduced in the dapagliflozin group(P<0.05).(4)The results indicate that dapagliflozin inhibits oxidized low-density lipoprotein-induced endothelial pyroptosis and ameliorates endothelial cell dysfunction.

摘要

BACKGROUND:Congenital clubfoot mainly manifests as abnormal bone itself and abnormal cartilage development.The bone morphogenetic protein(BMP)/drosophila mothers against decapentaplegic protein(Smad)signaling pathway can direct the development of bone and cartilage during embryonic period,but its role in the field of clubfoot etiology has not been confirmed in animal experiments. OBJECTIVE:To explore the mechanism by which the BMP/Smad signaling pathway is involved in the regulation of foot and ankle chondroplasia in a rat congenital clubfoot model. METHODS:Sprague-Dawley rats at 10 days of gestation with the same growth condition were randomly divided into experimental and control groups.The experimental group was intragastrically given 135 mg/kg retinoic acid to make the clubfoot model,while the control group was given the same amount of vegetable oil.The fetal rats were taken out after 21 days of gestation by cesarean section.In the experimental group,the 27 of 41 fetal rats had clubfoot,with a deformity rate of 65.9%;in the control group,no clubfoot was observed in all the 36 fetuses.The ankles tissues of the rats were collected for hematoxylin-eosin staining.Western blot assay,RT-qPCR and immunohistochemistry were performed to detect the expression levels of Smad5 and P-Smad5,the core proteins of the BMP/Smad signaling pathway,as well as SP7 and Sox9,the downstream proteins of the BMP/Smad signaling pathway. RESULTS AND CONCLUSION:Compared with the control group,hematoxylin-eosin staining showed that the cartilage matrix in the foot and ankle tissues increased and the gap between the bones increased in the experimental group.Immunohistochemical findings showed that the expression levels of Smad5 and SP7 decreased in the experimental group,while the mRNA expression of Sox9 increased.RT-qPCR results showed that the mRNA expression of Smad5 and SP7 decreased,while the mRNA expression of Sox9 increased in the foot and ankle tissues of rats in the experimental group.Western blot results showed that P-Smad5/Smad5 expression and SP7 expression were decreased and Sox9 expression was increased in the ankle of rats in the experimental group.To conclude,the occurrence of cartilage abnormalities in the foot and ankle of the rat model of congenital clubfoot is associated with impaired transmission of the BMP/Smad signaling pathway.
