Coronary restenosis is an important cause of poor long-term prognosis in patients with coronary heart disease. Here, we show that lysine methyltransferase SMYD2 expression in the nucleus is significantly elevated in serum- and PDGF-BB-induced vascular smooth muscle cells (VSMCs), and in tissues of carotid artery injury-induced neointimal hyperplasia. Smyd2 overexpression in VSMCs (Smyd2-vTg) facilitates, but treatment with its specific inhibitor LLY-507 or SMYD2 knockdown significantly inhibits VSMC phenotypic switching and carotid artery injury-induced neointima formation in mice. Transcriptome sequencing revealed that SMYD2 knockdown represses the expression of serum response factor (SRF) target genes and that SRF overexpression largely reverses the inhibitory effect of SMYD2 knockdown on VSMC proliferation. HDAC3 directly interacts with and deacetylates SRF, which enhances SRF transcriptional activity in VSMCs. Moreover, SMYD2 promotes HDAC3 expression via tri-methylation of H3K36 at its promoter. RGFP966, a specific inhibitor of HDAC3, not only counteracts the pro-proliferation effect of SMYD2 overexpression on VSMCs, but also inhibits carotid artery injury-induced neointima formation in mice. HDAC3 partially abolishes the inhibitory effect of SMYD2 knockdown on VSMC proliferation in a deacetylase activity-dependent manner. Our results reveal that the SMYD2-HDAC3-SRF axis constitutes a novel and critical epigenetic mechanism that regulates VSMC phenotypic switching and neointimal hyperplasia.

Gliomas are the most common primary intracranial tumors in adults, among which high-grade glioma patients are characterized by short survival and poor prognosis. The diagnosis, treatment, evaluation of effective treatments, and prognosis prediction of high-grade gliomas are of great significance for improving patient survival. Conventional enhanced magnetic resonance imaging has deficiencies in delineating tumor extent, identifying tumor progression and treatment-related changes. Therefore, there is a broad consensus to incorporate amino acid PET, and 18F-FET PET inparticular, into the diagnostic and therapeutic process of high-grade gliomas. In this article, we review the new research progress of 18F-FET PET in the diagnosis and treatment of adult high-grade glioma in recent years.

Triggering receptor expressed on myeloid cells-1 (TREM-1) is a member of the immunoglobulin superfamily. As an amplifier of the inflammatory response, TREM-1 is mainly involved in the production of inflammatory mediators and the regulation of cell survival. TREM-1 has been studied in infectious diseases and more recently in non-infectious disorders. More and more studies have shown that TREM-1 plays an important pathogenic role in kidney diseases. There is evidence that TREM-1 can not only be used as a biomarker for diagnosis of disease but also as a potential therapeutic target to guide the development of novel therapeutic agents for kidney disease. This review summarized molecular biology of TREM-1 and its signaling pathways as well as immune response in the progress of acute kidney injury, renal fibrosis, diabetic nephropathy, immune nephropathy, and renal cell carcinoma.

Objective:To investigate the expression of microRNA-34a (miR-34a)and tumor necrosis factor-α (TNF-α) in lung injury induced by lipopolysaccharides (LPS) in neonatal rats with acute respiratory distress syndrome (ARDS). The expression of mirna-34a and tumor necrosis factor-α (TNF-α) in lung injury induced by lipopolysaccharides (LPS) was determined by tumor necrosis factor.Methods:A total of 80 7-day-old newborn SD rats were randomly(random number) divided into two groups, 40 in each group, NARDS animal models were established by intraperitoneal injection of 4 mg/kg LPS solution for 3,6,12 and 24 hours respectively. Normal control group was established by intraperitoneal injection of 4 mL/kg isotonic Nacl solution. The wet/dry weight ratio of lung was measured to observe the changes of lung histopathology. The expression of miR-34a in lung tissues and cells was detected by quantitative real-time PCR (qrt-PCR).Results:the wet/dry weight of lung in the experimental group was significantly higher than that in the control group. Hematoxylin-eosin (HE) staining showed diffuse changes in lung tissue, thickening of alveolar septum, partial alveolar fusion and decreased number of alveoli in experimental group. The expression levels of miR-34a and TNF-α in the experimental group were higher than those in the control group at each time point.Conclusions:It is speculated that miR-34a can promote the release of more inflammatory factors by positively regulating the expression of TNF-α, thus affecting the occurrence and development of lung injury. The expression of miR-34a positively correlated with TNF-α. miR-34a may affect the regulation mechanism of lung injury by mediating the expression of TNF-α through some signal pathway or inflammatory reaction, it provides a new therapeutic target for the treatment of neonatal acute respiratory distress syndrome (NARDS).
