Ureides are generally similarly gathered in response to UV-C irradiation along with injury however in different ways remobilized throughout recovery within Arabidopsis simply leaves.
Exosomal circ‑HMGCS1 was increased in the serums and cells of colon cancer patients. Circ‑HMGCS1 was downregulated by sevoflurane treatment in colon cancer cells and circ‑HMGCS1 overexpression could restore the effect of sevoflurane on colon cancer cell development. miR‑34a‑5p was a target of circ‑HMGCS1 and miR‑34a‑5p inhibition reversed the effect of circ‑HMGCS1 silencing on colon cancer cell progression. Moreover, circ‑HMGCS1 knockdown suppressed SGPP1 expression via sponging miR‑34a‑5p. Knockdown of circ‑HMGCS1 blocked tumor growth in vivo. In conclusion, sevoflurane inhibited colon cancer progression by modulating the exosome‑transmitted circ‑HMGCS1/miR‑34a‑5p/SGPP1 axis.The enhanced migratory ability of endometrial stromal cells (ESCs) is a key factor in the formation of functional endometrium‑like tissues outside the uterine cavity during endometriosis (EMS). Although accumulating evidence has suggested the importance of microRNAs (miRNAs) in the pathogenesis of EMS, the role of particular miRNAs in the invasiveness of ESCs remain poorly understood. In the present study, the function of miRNAs in the invasiveness of ESCs, along with the associated underlying mechanism involved, were investigated. Initially, the expression patterns of miRNAs in the ectopic and eutopic endometrium isolated from patients with EMS were analyzed using microarray. MicroRNA‑202‑5p (miR‑202) was selected for further study due to its previously reported suppressive effects on the invasion in various types of cancers. The expression of miR‑202 and K‑Ras in eutopic and ectopic endometrioma tissues were detected using reverse transcription‑quantitative PCR, immunohistochemistry and western blotting. Thion attenuated the inhibitory role of miR‑202 overexpression in ESC invasion. The K‑Ras/Raf1/MEK/ERK signaling pathway was also blocked by miR‑202 overexpression. These findings suggested that miR‑202 inhibited ESC migration and invasion by inhibiting the K‑Ras/Raf1/MEK/ERK signaling pathway, rendering miR‑202 a candidate for being a therapeutic target for EMS.SP600125 is a classic inhibitor of c‑Jun‑N‑terminal kinase (JNK) that is widely used in numerous medicinal studies, but its administration regimen has yet to be optimized. In the present study, intraperitoneal (i.p.) and intragastric (i.g.) injections of 15 mg/kg SP600125 was performed in mice to compare the inhibitory effect against JNK signalling in cholestasis induced by α‑naphthylisothiocyanate (ANIT). SP600125 at a dose of 15 mg/kg administered by i.p. substantially decreased ANIT‑induced liver injury as observed by biochemical and histopathological examinations. The adaptation of bile acid synthesis was inhibited in the A‑SP‑i.p. group compared with that in the A‑SP‑i.g. group, as indicated by the expression analysis of CYP7A1 and CYP8B1. The transcription of the pro‑inflammatory factors IL‑6, IL‑1β, ICAM‑1 and IL‑10 supported the differential toxic responses. Western blot analysis revealed that JNK signalling activated by ANIT was inhibited more markedly in the A‑SP‑i.p. group than in the A‑SP‑i.g. DAPT inhibitor mouse group. The peak concentration and the AUC0‑24 of SP600125 in the A‑SP‑i.p. group were 5‑fold and 1.56‑fold higher, respectively, compared with those in the A‑SP‑i.g. group. These data indicated that i.p. administration of SP600125 produced a high plasma exposure profile, which directly determined its efficacy of blocking the JNK signalling. This effect of SP600125 on the JNK pathway may provide an optimized design for future in vivo investigations.Liver fibrosis (LF) is a healing response to wounds resulting in liver injury that can cause liver failure or even cancer without functional prevention. Resveratrol (RSV) has been suggested to exert biological effects against various human diseases. MicroRNA‑20a (miRNA/miR‑20a) has been shown to promote disease progression. The present study aimed to assess the mechanisms through which RSV induces autophagy and activates the miR‑20a‑mediated phosphatase and tensin homolog (PTEN)/PI3K/AKT signaling pathway in LF. First, a rat model of carbon tetrachloride (CCL4)‑induced LF and a cell model of platelet‑derived growth factor (PDGF)‑BB‑stimulated HSC‑T6 cells were established for use in subsequent experiments. Subsequently, RSV at a range of concentrations was injected into the model rats with LF. Indicators related to liver injury, oxidative stress and fibrosis were determined in the rats with LF. The RSV‑treated HSC‑T6 cells were subjected to transfection with miR‑20a mimic and PTEN overexpression plasmid to assess the levels of liver injury and LF. A dual‑luciferase reporter gene assay was performed to verify the binding sites between PTEN and miR‑20a. RSV was found to alleviate LF in rats, and autophagy was enhanced in the rats with LF following RSV treatment. Furthermore, the activation of the PTEN/PI3K/AKT axis attenuated LF, which was reversed by transfection with miR‑20a mimic. RSV reversed the inhibitory effects of miR‑20a on PTEN expression, reducing miR‑20a expression and promoting PTEN, PI3K and p‑AKT protein expression, thus attenuating LF. On the whole, the present study demonstrates that RSV induces autophagy and activates the miR‑20a‑mediated PTEN/PI3K/AKT signaling pathway to attenuate LF. These findings may lead to the development of potential therapeutic strategies for LF.Circular RNAs (circRNAs) have been reported to be involved in the progression of colorectal cancer (CRC). However, the biological role of circCCDC66 in CRC remains unclear. Therefore, the present study aimed to elucidate the mechanisms through which circCCDC66 affects the hypoxia‑induced progression of CRC. It was found that hypoxia promoted the progression of CRC and upregulated the expression of circCCDC66. Furthermore, circCCDC66‑knockdown reduced viability, migration and invasion, and enhanced the apoptosis of hypoxia‑exposed CRC cells. Using the starBase database, it was identified that circCCDC66 may bind to miR‑3140. Subsequently, it was confirmed that circCCDC66 serves as a sponge of miR‑3140 and the depletion of miR‑3140 partly abolished the effects of circCCDC66 on the phenotype of hypoxia‑exposed CRC cells. In addition, miR‑3140 was validated to inhibit the autophagy pathway. The use of an autophagy inducer partially reversed the miR‑3140 overexpression‑induced inhibition of the viability and invasion, and the promotion of the apoptosis of hypoxia‑exposed CRC cells.
