BackgroundBoth omacetaxine (HHT) and curcumin were shown to exhibit anti-proliferative effect on lymphoma cells. However, the role of combination of HHT with curcumin (HHT/curcumin combination) on lymphoma cells remains unclear. Thus, this study aimed to investigate the effect of HHT/curcumin combination on the proliferation, migration, and angiogenesis of lymphoma cells.MethodsCell counting kit-8 (CCK-8), Ki67 immunofluorescence and transwell assays were used to assess the viability, proliferation and migration of U937 and Raji cells respectively. In addition, tube formation assay was used to determine the effects of HHT/curcumin combination on angiogenesis in human umbilical vein endothelial cells (HUVECs).ResultsIn this study, we found that HHT/curcumin combination significantly inhibited the proliferation, migration and invasion in U937 and Raji cells (all P < 0.01). In addition, combination treatment markedly inhibited the secreted levels of vascular endothelial growth factor (VEGF)-(A-D) (all P < 0.01) in Raji cells. Moreover, combination treatment exhibited anti-tumor effects in Raji cells, as shown by the decreased signals of phosphorylated VEGF receptor 2 (p-VEGFR2) and phosphorylated protein kinase B (p-Akt) (all P < 0.01). Meanwhile, combination treatment inhibited VEGFA levels (P < 0.01) in exosomes derived from Raji cells. Application of exosomes with downregulated VEGF to HUVECs notably inhibited proliferation, migration and tube formation of HUVECs, evidenced by the decreased signals of p-Akt, angiogenin-1, matrix metallopeptidase 2 (MMP2) and matrix metallopeptidase 9 (MMP9) (all P < 0.01).ConclusionOur findings indicated that combination of HHT and curcumin could inhibit lymphoma cell growth and angiogenesis via inhibition of VEGF/Akt signaling pathway. These results suggested that HHT combined with curcumin might be regarded as a promising therapeutic approach for the treatment of lymphoma.

Ischemic stroke is a major cerebrovascular disease resulting from a transient or permanent local reduction of cerebral blood flow. Angiogenesis plays an important role in cerebral microvascular repair after ischemic stroke. This study aimed at investigating the effect of NF-E2-related factor 2 (Nrf2) on the angiogenesis of mouse cerebral microvascular endothelial bEnd.3 cells in a hypoxic environment. We found that Nrf2 expression was temporarily increased in hypoxia-induced bEnd.3 cells. Knockdown of Nrf2 inhibited the proliferation, migration, as well as tube formation in hypoxia-induced bEnd.3 cells. Meanwhile, vascular endothelial growth factor and PI3K/Akt signaling pathways were identified to be regulated by Nrf2 in hypoxia-induced bEnd.3 cells. It was found that silencing of Nrf2 downregulated the expression levels of NAD(P)H:quinine oxidoreductase-1, vascular endothelial growth factor, p-Akt, and heme oxygenase-1 in hypoxia-induced bEnd.3 cells. Data suggested that hypoxia induced the transient increase of Nrf2, which plays a key role in the angiogenesis of cerebral microangiogenesis, and that Nrf2 regulates the proliferation, migration, as well as tube formation likely through PI3K/Akt signaling pathway in hypoxia-induced bEnd.3 cells. Our study provides proof of concept for the modulation of Nrf2, so as to tilt the balance toward angiogenesis, representing a therapeutic strategy for hypoxia or ischemia disorders such as stroke.

Abstract Background: The present study explored the possible functions and the underlying mechanism of long Non-coding RNA LINC02085 in rheumatoid arthritis (RA). Methods: Primary fibroblast-like synoviocytes (FLS) were separated from synovial tissues and was established cell lines, then cultured for subsequent cell experiments by transfecting different vectors. Rat with AA were injected with sh-LINC02085. The progression of AA was explored by measuring arthritis score and histologic analysis. ELISA analysis was employed to detect the levels of inflammatory cytokines. CCK8 assay, migration and invasion assays were used to evaluate the proliferation, migration and invasion abilities of cells, respectively. Besides, the levels of the the PI3K/AKT pathway-related proteins were measured by WB and IF. Results: The expression level of LINC02085 was significant high in patients with RA, and positively associated with clinical indexes. We found that LINC02085 was upregulated in RA -FLS and TNF-αstimulated. And overexpression of LINC02085 could promote proliferation, migration and invasion induced by TNF-α, through upregulating the levels of TNF-αand TNFAIP2 and promoting the activation of PI3K/AKT pathway. Whereas downexpression of LINC02085 received the opposite results. Knockdown of LINC02085 significantly ameliorated the progression of AA reflected by decreased arthritis score and cartilage destruction. Conclusion: The present study revealed that LINC02085 could regulate cell growth and inflammatory response of RA-FLS by activating the PI3K/ AKT signaling pathway, subsequently playing important roles in promoting the occurrence and development of RA.
