Unveiling the mechanism of miR-122-5p in the mediation of forkhead box O3 (FOXO3) in regards to cochlear hair cell damage provides an effective solution for the treatment of ear hearing disorders. An oxidative stress model using a mouse cochlear hair cell line (HEI-OC1) was established via hydrogen peroxide (H2O2). Then HEI-OC1 cells were transfected with miR-122-5p mimic, miR-122-5p inhibitor, and lentiviral vector FOXO3-WT/MUT. Cell viability and apoptosis rate were determined by MTT assay and flow cytometry. Reactive oxygen species (ROS) were observed by confocal laser scanning microscopy. Bcl-2, Bax, capase-3 and c-caspase-9 levels were quantified by western blot analysis and quantitative reverse transcription polymerase chain reaction (RT-qPCR). selleck compound Enzyme-linked immunosorbent assay (ELISA) was used to detect superoxide dismutase (SOD) and malondialdehyde (MDA) levels, and flow cytometry was performed to measure the mitochondrial membrane potential levels. In the HEI-OC1 oxidative stress model after transfection, the miR-122-5p level was decreased, whereas the FOXO3 level was increased, Moreover, the increased FOXO3 level diminished the cell viability, but promoted cell apoptosis. Apart from this, the Bcl-2 level was downregulated, while levels of Bax, c-caspase-3, c-caspase-9, ROS and MDA were upregulated. Meanwhile, the mitochondrial membrane potential level was also elevated. Overexpression of miR-122-5p was able to partially offset the effects of FOXO3 in the H2O2-treated HEI-OC1 cells. Collectively, miR-122-5p restrained the decrease in HEI-OC1 cell viability and apoptosis induced by treatment with H2O2.Alzheimer's disease (AD) is a progressive neurodegenerative dementia with the key pathological hallmark of amyloid deposits that may induce mitochondrial dysfunction. Ginkgolide K (GK) has been proven to have neuroprotective effects. The present study sought to explore the neuroprotective effect of GK through regulation of the expression of mitochondrial Ca2+ uniporter (MCU) in the pathology of AD. SH-SY5Y cells were cultured and the expression of MCU was enhanced by transfection of MCU recombinant vectors or knockdown by MCU small interfering RNA. The cells were treated with GK and amyloid β (Aβ). Thereafter, the effects of GK, MCU expression and Aβ on viability and apoptosis of SH-SY5Y cells were examined via a WST-1 assay, flow cytometry and Caspase-3/8 activity assays, respectively. The effects of GK, MCU expression and Aβ on the calcium levels in mitochondria were also examined. The regulatory effect of GK on MCU expression was examined by reverse transcription-quantitative PCR and western blot analysis.y be a promising strategy for treating AD.Myocardial infarction is one of the primary causes of mortality in patients with coronary heart disease worldwide. Early treatment of acute myocardial infarction restores blood supply of ischemic myocardium and decreases the mortality risk. However, when the interrupted myocardial blood supply is recovered within a certain period of time, it causes more serious damage to the original ischemic myocardium; this is known as myocardial ischemia/reperfusion injury (MIRI). The pathophysiological mechanisms leading to MIRI are associated with oxidative stress, intracellular calcium overload, energy metabolism disorder, apoptosis, endoplasmic reticulum stress, autophagy, pyroptosis, necroptosis and ferroptosis. These interplay with one another and directly or indirectly lead to aggravation of the effect. In the past, apoptosis and autophagy have attracted more attention but necroptosis and ferroptosis also serve key roles. However, the mechanism of MIRI has not been fully elucidated. The present study reviews the mechanisms underlying MIRI. Based on current understanding of the pathophysiological mechanisms of MIRI, the association between cell death-associated signaling pathways were elaborated, providing direction for investigation of novel targets in clinical treatment.Bile duct hamartoma in the liver (LBDH) is relatively rare among the hepatic space-occupying lesions that occur in adults, and the malignant transformation of LBDH is even rarer. In the present case report, a 63-year-old male was found to have two space-occupying lesions in the right lobe of the liver upon ultrasound examination. Enhanced computed tomography (CT) suggested benign hepatic haemangioma, and contrast-enhanced ultrasonography (CEUS) suggested well-differentiated hepatocellular carcinoma. The final pathology results revealed the malignant transformation of LBDH into well-differentiated intrahepatic cholangiocarcinoma. Improved recognition of this type of rare disease can be obtained by radiographic analysis of this case. These findings contribute to a better understanding of the enhanced development pattern of this disease on contrast-enhanced CT, as well as on CEUS.The expression profile and role of yes-associated protein (YAP) in occurrence and development of breast cancer is ambiguous. The present study aimed to explore the relationship among the YAP, β-catenin and smoothened (SMO) signaling pathways to provide a theoretical basis for the clinical diagnosis and treatment of invasive breast cancer. Immunohistochemistry was used to determine the protein expression levels of YAP, β-catenin and SMO in tumor, tumor-adjacent and normal breast tissue. The possible association between the expression levels of these three proteins and the clinicopathological features of patients with breast cancer was then analyzed by the χ2 test. The protein expression of YAP was found to be downregulated, whilst β-catenin and SMO expression were found to be upregulated in tumor tissues as compared with that in normal breast tissues. In addition, the expression of YAP in breast cancer tissues was found to be associated with that of human epidermal growth factor receptor 2 (HER2), progesterone and estrogen receptors. By contrast, the protein expression of β-catenin and SMO in breast cancer tissues was only associated with HER2. There was a negative correlation between the expression of YAP and SMO protein in breast cancer tissues. Compared with that in the changes in each of YAP, β-catenin and SMO protein expression levels individually, their combined changes in expression were demonstrated to associate significantly with the tumor histological grade. To conclude, data from the present study suggest that the combined protein expression of YAP, β-catenin and SMO can be used as a prognostic indicator for the treatment of invasive breast cancer.In patients with diabetes, the Wnt/β-catenin pathway in vascular smooth muscle cells (VSMCs) is continuously activated by low-intensity inflammation, which leads to the osteoblastic differentiation of these cells and the deposition of calcium and phosphorus in blood vessels. The aim of the present study was to determine whether long intergenic non-coding RNA-erythroid pro-survival (lincRNA-EPS) was able to ameliorate vascular calcification (VC) associated with diabetes. VSMCs isolated from C57BL/6 mice were transfected with lincRNA-EPS overexpression vector in vitro and their osteoblastic differentiation was evaluated under high-glucose conditions. In addition, a mouse model of diabetes was established, which included a lincRNA-EPS knockout group and a lincRNA-EPS high expression group. Blood vessel samples from the mice were examined to determine the degree of calcification. The levels of inflammatory factors in serum were also detected. The VSMCs transfected with lincRNA-EPS overexpression vector exhibited less osteoblastic differentiation and migration and significantly lower levels of Wnt pathway-associated proteins than those transfected with empty control. Furthermore, the in vivo experiments revealed that the overexpression of lincRNA-EPS significantly reduced VC in diabetic mice. Therefore, on the basis of these findings, it is suggested that lincRNA-EPS overexpression may provide a novel and effective method for the treatment of VC in patients with diabetes.The transcription factor, forkhead box P2 (FOXP2) has tumor-suppressive effects in several types of cancer. However, the regulatory role and underlying mechanism of FOXP2 in thyroid cancer (THCA) is not completely understood. In the present study, the mRNA expression levels of FOXP2 and ribosomal protein S6 kinase A6 (RPS6KA6) were evaluated using the GEPIA database and THCA cell lines. The association between FOXP2 and RPS6KA6 was analyzed using the LinkedOmics, and GEPIA databases. Then, the binding sites of FOXP2 and the RPS6KA6 promotor was predicted using the JASPAR database, and verified using a dual-luciferase reporter assay and chromatin immunoprecipitation. In addition, functional assays investigating FOXP2 and RPS6KA6 were conducted in the TPC-1 cell line. The data showed that FOXP2 and RPS6KA6 mRNA expression levels were decreased in the THCA tissues, and cell lines. Overexpression of FOXP2 inhibited cell proliferation and promoted apoptosis in the THCA cell lines. Furthermore, RPS6KA6 mRNA expression levels were reduced in THCA and were correlated with FOXP2 expression level. Mechanistic studies revealed that FOXP2 binds directly to the promotor region of RPS6KA6 and modulated the expression level of RPS6KA6 transcriptionally. In addition, rescue experiments showed that knockdown of RPS6KA6 expression reversed the effects of FOXP2 overexpression on THCA cell proliferation and apoptosis, and the regulation of FOXP2/RPS6KA6 may be associated with the PI3K/AKT pathway. In summary, FOXP2 was associated with the proliferation and apoptosis of human THCA cells via the transcriptional activation of RPS6KA6. The FOXP2/RPS6KA6 axis could be a promising target for the treatment of THCA.The present study presents the experience gained in the Newborn Intensive Care Unit (NICU) of 'Maria S. Curie' Emergency Clinical Hospital for Children in Bucharest (Romania) after performing a series of bedside surgery interventions on newborns with congenital diaphragmatic hernia (CDH). We conducted a retrospective analysis of the data for all patients operated on-site between 2011 and 2020, in terms of pre- and post-operative stability, procedures performed, complications and outcomes. An analysis of a control group was used to provide a reference to the survival rate for non-operated patients. The present study is based on data from 10 cases of newborns, surgically operated on, on average, on the fifth day of life. The main reasons for operating on-site included hemodynamical instability and the need to administer inhaled nitric oxide (iNO) and high-frequency oscillatory ventilation (HFOV). There were no unforeseen events during surgery, no immediate postoperative complications and no surgery-related mortality. One noticed drawback was the unfamiliarity of the surgery team with the new operating environment. Our experience indicates that bedside surgery improves the likelihood of survival for critically ill neonates suffering from CDH. No immediate complications were associated with this practice.Chronic kidney disease (CKD) has a worldwide prevalence of higher than 10% with an increasing mortality rate. As it involves the deterioration of renal function, it represents a serious risk to human health and, if left untreated, significantly lowers the quality of the patient's life. CKD is characterized by renal fibrosis. Studies have shown that transforming growth factor β1 (TGF-β1), a key driving factor of renal fibrosis, is closely related to the activation of renal fibrosis pathways such as endoplasmic reticulum stress (ERS). Tauroursodeoxycholic acid (TUDCA), an endogenous bile acid derivative, can effectively inhibit endogenous ERS. Here, we explored the effects and actions of TUDCA on renal fibrosis by establishing a renal mesangial cell (RMC) model. The RMC was stimulated with TGF-β1, and PCR and western blotting were used to detect the expression of ERS-related chaperone proteins and fibrotic indicators. The expression of glucose-regulated protein 78 (GRP78) was silenced in RMC cells to investigate the role of GRP78 in renal fibrosis.
