“…Qu et al . (34) have proposed that myocardial fibrosis can be suppressed through the activation of the glycoprotein 130/JAK2/STAT3 axis in cardiomyocytes. Analysis into the role of DOK2 in the regulation of the JAK2/STAT3 signaling pathway and the EMT of PMCs demonstrated that silencing of DOK2 decreased the expression of E‐cadherin while acting to elevate the expression of α‐SMA and vimentin and JAK2 and STAT3 phosphorylation.…”

Peritoneal fibrosis (PF) represents a well‐recognized complication associated with continuous ambulatory peritoneal dialysis therapy, characterized by a reversible epithelial‐to‐mesenchymal transition (EMT) at the early stage. The aim of the current study was to investigate the effects linked with the long noncoding RNA (IncRNA) AK089579 on the EMT of peritoneal mesothelial cells (PMCs) as well as the associated regulatory mechanisms of AK089579 downstream of tyrosine kinase 2 (DOK2) and microRNA‐296‐3p (miR‐296‐3p). Enrichment analysis, gene intersection association analysis, and a gene‐gene intersection network were initially constructed to ascertain whether AK089579 regulated the expression of DOK2 through the mediation of miR‐296‐3p via the Janus kinase 2 (JAK2)/signal transducer and activator of transcription 3 (STAT3) signaling pathway in PF. After the PF mouse model had been constructed, the expression of the proteins associated with the JAK2/STAT3 signaling pathway and EMT and PMC migration and invasion were all determined accordingly. Based on the obtained results, AK089579 was determined to function as a competing endogenous RNA for miR‐296‐3p while acting to up‐regulate the expression of DOK2, which is a target gene of miR‐296‐3p. AK089579 was detected to confer an inhibitory effect on the activation of the JAK2/STAT3 signaling pathway, whereby the migration and invasion of PMCs among the mice models were suppressed. Meanwhile, up‐regulated miR‐296‐3p and down‐regulated DOK2 produced contrasting effects when compared with the aforementioned findings. Treatment with wpl0066, a JAK2/STAS3 signaling pathway inhibitor, was shown to reverse the effects exerted by up‐regulated miR‐296‐3p. Taken together, the central findings of the current study present evidence highlighting the capability of the IncRNA AK089579 to bind competitively to miR‐296‐3p and indirectly enhance the expression of DOK2, which in turn suppresses the activation of the JAK2/STAT3 signaling pathway, whereby the EMT, migration, and invasion of PMCs was inhibited in PF.—Zhang, X.

“…Several studies have reported that it contains various types of secondary metabolites, such as oils, flavonoids, sterols and cardiac glycosides [ 1 , 2 , 3 ], and shows antioxidant [ 1 ], antibacterial [ 2 ] and beneficial cardiac [ 4 ] activities. Clinical research suggests that it is useful for heart failure [ 5 , 6 ]. Therefore, studies of the phytochemical activity and structure–activity relationships of constituents of Lepidium apetalum Willd were developed in our lab.…”

Lepidium apetalum Willd has been used to reduce edema and promote urination. Cis-desulfoglucotropaeolin (cis-DG) and trans-desulfoglucotropaeolin (trans-DG) were isolated from Lepidium apetalum Willd, and caused a significant increase in cell viability in a hypertonic model in NRK52e cells. In the hypertonic model, cis-DG and trans-DG significantly promoted the cell viability of NRK52e cells and inhibited the elevation of Na+ in the supernatant, inhibited the renin-angiotensin-aldosterone (RAAS) system, significantly reduced the levels of angiotensin II (Ang II) and aldosterone (ALD), and lowered aquaporin-2 (AQP2) and Na+–K+ ATP content in renal medulla. After treatment with cis-DG and trans-DG, expression of calcineurin (CAN) and Ca/calmodulin-dependent protein kinase II (CaMK II) was decreased in renal tissue and Ca2+ influx was inhibited, thereby reducing the secretion of transforming growth factor-β (TGFβ), reversing the increase in adhesion and inflammatory factor E-selectin and monocyte chemotactic protein 1 (MCP-1) induced by high NaCl, while reducing oxidative stress status and decreasing the expression of cyclooxygenase-2 (COX2). Furthermore, inhibition of protein kinase C (PKC) expression also contributed to these improvements. The cis-DG and trans-DG reduced the expression of p-p44/42 MAPK, p-JNK and p-p38, inhibited the phosphorylation of the MAPK signaling pathway in NRN52e cells induced by high salt, decreased the overexpression of p-p38 and p-HSP27, and inhibited the overactivation of the p38-MAPK signaling pathway, suggesting that the p38-MAPK pathway may play a vital role in the hypertonic-induced adhesion and inflammatory response. From the results of this study, it can be concluded that the mechanism of cis-DG and trans-DG may mainly be through inhibiting the p38-MAPK signaling pathway, inhibiting the excessive activation of the RAAS system, and thereby reducing adhesion and inflammatory factors.

Background. Luhong formula (LHF)—a traditional Chinese medicine containing Cervus nippon Temminck, Carthamus tinctorius L., Astragalus membranaceus (Fisch.) Bge. var. mongholicus (Bge.) Hsiao, Codonopsis pilosula (Franch.) Nannf., Cinnamomum cassia Presl, and Lepidium apetalum Willd—is used in the treatment of heart failure, but little is known about its mechanism of action. We have investigated the effects of LHF on antifibrosis. Methods. Forty-eight SD male rats were randomly assigned into six groups (n = 8), model group, sham-operation group, perindopril group (0.036 mg/ml), LHF high doses (LHF-H, 1.44 g/mL), LHF middle doses (LHF-M, 0.72 g/mL), and LHF low doses (LHF-L, 0.36 g/mL). Except the sham-operation group, the other groups were received an abdominal aorta constriction to establish a model of myocardial hypertrophy. The HW and LVW were measured to calculate the LVW/BW and HW/BW. ELISA was used to detect the serum concentration of BNP. The expressions of eNOS, TGF-β1, caspase-3, VEGF, and VEGFR2 in heart tissues were assessed by western blot analysis. mRNA expressions of eNOS, Col1a1, Col3a1, TGF-β1, VEGF, and VEGFR2 in heart tissues were measured by RT-PCR. The specimens were stained with hematoxylin-eosin (HE) and picrosirius red staining for observing the morphological characteristics and collagen fibers I and III of the myocardium under a light microscope. Results. LHF significantly lowered the rat’s HW/BW and LVM/BW, and the level of BNP in the LHF-treated group compared with the model group. Histopathological and pathomorphological changes of collagen fibers I and III showed that LHF inhibited myocardial fibrosis in heart failure rats. Treatment with LHF upregulated eNOS expression in heart tissue and downregulated Col1a1, Col3a1, TGF-β1, caspase-3, VEGF, and VEGFR2 expression. Conclusion. LHF can improve left ventricular remodeling in a pressure-overloaded heart failure rat model; this cardiac protective ability may be due to cardiac fibrosis and attenuated apoptosis. Upregulated eNOS expression and downregulated Col1a1, Col3a1, TGF-β1, caspase-3, VEGF, and VEGFR2 expression may play a role in the observed LHF cardioprotective effect.
