In conclusion, senescence of vascular cells promotes the development of age-related disorders, including heart failure, diabetes, and atherosclerotic diseases, while suppression of vascular cell senescence ameliorates phenotypic features of aging in various models. Recent findings have indicated that specific depletion of senescent cells reverses age-related changes. Although the biological networks contributing to maintenance of homeostasis are extremely complex, it seems reasonable to explore senolytic agents that can act on specific cellular components or tissues. Several clinical trials of senolytic agents are currently ongoing. Survivors of hematopoietic stem cell transplantation are prone to premature aging, and one pilot clinical study is designed to test whether dasatinib and quercetin (D + Q) can suppress aging in these patients (NCT02652052). Another clinical trial is testing whether D + Q reduces pro-inflammatory cells obtained by skin biopsy in patients with idiopathic pulmonary fibrosis (NCT02874989). Furthermore, a clinical trial is ongoing to determine whether D + Q can reduce the senescent cell burden and frailty in patients with chronic kidney disease, as well as improving the function of adipose tissue-derived mesenchymal stem cells (NCT02848131). So far, only D + Q has been assessed in the clinical setting, and none of the current clinical trials are testing whether senolytic agents can inhibit cardiovascular disorders. However, depletion of senescen...

This study examined how two aesthetic features of infographics affect people's evaluation of information presented in infographic: colour and visual complexity. The findings suggested colour and visual complexity were both strong predictors of information evaluation in infographic and they should be chosen carefully in the design of infographics.

Authors: Kim TJ, Song J, Kim YS, Huh J, Kang IS, Yang JH, Jun TG Abstract OBJECTIVES: We aimed to investigate the outcome of tricuspid valve repair (TVR) performed concomitantly with pulmonary valve replacement in repaired tetralogy of Fallot (TOF) patients. DESIGN: This retrospective study included all patients who underwent pulmonary vale replacement from 2000 to 2016 after TOF correction. TVR patient data were compared to those of patients who underwent pulmonary vale replacement alone. RESULTS: Thirty-eight patients were enrolled. The degree of tricuspid regurgitation was significantly decreased after o...

In conclusion, it was identified that silencing of miR‑193a‑3p through hypermethylation can promote HER2 positive breast cancer progress by targeting GRB7, ERK1/2 and FOXM1 signaling. The function of miR‑193a‑3p in HER2 positive breast cancer implicates its potential application in therapy. PMID: 31017268 [PubMed - in process]

MicroRNA‑576‑3p inhibits the migration and proangiogenic abilities of hypoxia‑treated glioma cells through hypoxia‑inducible factor‑1α. Int J Mol Med. 2019 Jun;43(6):2387-2397 Authors: Hu Q, Liu F, Yan T, Wu M, Ye M, Shi G, Lv S, Zhu X Abstract The most common and aggressive type of brain cancer in adults is glioblastoma multiforme (GBM), and hypoxia is a common feature of glioblastoma. As the histological features of glioma include capillary endothelial cell proliferation, they are highly prone to invading the surrounding normal brain tissue, which is often one of the reasons for the ...

Role of the thioredoxin interacting protein in diabetic nephropathy and the mechanism of regulating NOD‑like receptor protein 3 inflammatory corpuscle. Int J Mol Med. 2019 Jun;43(6):2440-2450 Authors: Gu C, Liu S, Wang H, Dou H Abstract Inflammatory response serves an important role in diabetic nephropathy (DN); however, the mechanism of inflammatory response results in renal damage is not yet clear. The aim of the present study was to investigate the role of the thioredoxin interacting protein (TXNIP)/NOD‑like receptor protein 3 (NLRP3) axis‑mediated activation of NLRP3 inflammasome in DN. A di...

Detection of N6‑methyladenosine modification residues (Review). Int J Mol Med. 2019 Jun;43(6):2267-2278 Authors: Zhu W, Wang JZ, Xu Z, Cao M, Hu Q, Pan C, Guo M, Wei JF, Yang H Abstract Among a number of mRNA modifications, N6‑methyladenosine (m6A) modification is the most common type in eukaryotes and nuclear‑replicating viruses. m6A has a significant role in numerous cancer types, including leukemia, brain tumors, liver cancer, breast cancer and lung cancer. Although m6A methyltransferases are essential during RNA modifications, the biological functions of m6A and the underlying mechanisms rem...

In conclusion, IL‑18 served a dual function in colitis by regulating the function of goblet cells. The anti‑inflammatory effects of IL‑18 were observed in the early stage of colitis‑induced inflammation, while the pro‑inflammatory effects were observed in the later stages of the disease.

Abstract Mitochondria are crucial for neuronal cell survival and death through their functions in ATP production and the intrinsic pathway of apoptosis. Mitochondrial dysfunction is considered to play a central role in several serious human diseases, including neurodegenerative diseases, such as Parkinson's and Alzheimer's disease and ischemic neurodegeneration. The aim of the present study was to investigate the impact of transient global brain ischemia on the expression of selected proteins involved in mitochondrial dynamics and mitochondria‑associated membranes. The main foci of interest were the proteins mit...
