Furthermore, c-Myc knockdown markedly elevated the sensitivity of lung cancer cells to DOX, whereas over-expressing c-Myc markedly reversed the anti-tumor role of DOX, which was slightly diminished by miR-451a mimic. The in vivo experiments confirmed that miR-451a promoted the sensitivity of lung cancer cells-derived tumors to DOX treatment by reducing c-Myc. Therefore, our results revealed a new insight into DOX resistance of lung cancer cells and miR-451a could be considered as a potential therapeutic target to overcome drug resistance in lung cancer. The transcription factor nuclear factor erythroid-2 related factor 2 (Nrf2) is a dominant manager to inhibit oxidative and inflammatory damage. Fenretinide (Fen) is a novel agent, showing significant role in regulating oxidative stress and inflammatory response. However, its effects on lipopolysaccharide (LPS)-induced brain injury are still unclear. In the present study, we explored the regulatory role of Fen in LPS-triggered neuroinflammation, and the underlying molecular mechanisms. Results here indicated that Fen treatment markedly improved Nrf2 expression and nuclear translocation in mouse brain endothelial cell line bEnd.3 cells, and promoted Nrf2-antioxidant responsive element (ARE) transcription activity, as well as its down-streaming signals, which was Nrf2-dependent. Fen also exhibited cytoprotective role in LPS-stimulated bEnd.3 cells through improving anti-oxidant capacity and inhibiting inflammation by the blockage of nuclear factor-kappa B (NF-κB) signaling. Mouse model with brain injury induced by LPS, Fen administration markedly attenuated the behavior impairments, blood-brain-barrier (BBB) and the histological changes in hippocampus samples. Additionally, Fen attenuated oxidative stress and blunted inflammation in hippocampus of LPS-challenged mice. Therefore, results in the study highlighted the protective role of Fen against LPS-elicited brain injury. Smilax glabra Roxb. (SG) is a well-known traditional Chinese medicine that has been extensively used as both food and folk medicine in many countries. Although many beneficial health effects of SG and its primary components have been reported, their action on adipocyte function remains unknown. In the present study, we investigated the effects of the total flavonoids from Smilax glabra Roxb. (SGF) on lipid accumulation in mouse 3T3-L1 adipocytes and further elucidated its potential mechanism using RNA-Seq transcriptome technique. Our results showed that SGF exposure significantly decreased the lipid droplet size and the levels of cellular free fatty acids, while triglyceride accumulation was not affected by SGF. Transcriptome analysis revealed that SGF induced the expression of genes involved in triglyceride storage, fatty acid β-oxidation and mitochondrial biogenesis. Furthermore, we also observed an increased cellular ATP level and mitochondrial mass after SGF exposure, indicating that SGF enhanced mitochondrial function.  https://www.selleckchem.com/products/slf1081851-hydrochloride.html  The other relevant transcriptional changes appeared to be involved in AMPK/PGC-1α signaling, inflammatory response, as well as PI3K/AKT and calcium signaling pathways, which might contribute to the beneficial metabolic effects of SGF on adipocyte function. The results of Western blotting confirmed that SGF could increase the phosphorylation of AMPK while decrease the phosphorylation of AKT in adipocytes. Altogether, our results provided novel information about the molecular mechanism responsible for the effects of SGF on fat storage in adipocytes and highlights the potential metabolic benefits of SGF on human obesity and its related chronic diseases. Acute myeloid leukemia (AML) is a complicated disease of hematopoietic stem cell disorders. However, its pathogenesis mechanisms and therapeutic treatments still remain vague. Asperuloside (ASP) is an iridoid glycoside found in Herba Paederiae, and is a component from traditional Chinese herbal medicine. ASP has been suggested to have various pharmacological activities, such as anti-tumor and anti-inflammation. In this study, we explored the effects of ASP on apoptosis and endoplasmic reticulum (ER) stress in human leukemia cells and in human primary leukemia blasts. ASP treatments selectively reduced the cell viability of human leukemia cells and primary leukemia blasts in a dose-dependent manner. We also found that ASP induced cell death via promoting the cleavage of Caspase-9, -3 and poly (ADP-ribose) polymerase (PARP), which was along with the loss of mitochondrial membrane potential and Cyto-c release from the mitochondria. In addition, we found that ASP significantly induced ER stress in leukemia cells vated red blood cells. Together, our present results showed that ASP exerted anti-leukemic effects at least partially via inducing apoptosis regulated by ER stress, and suggested that ASP might be a novel and effective therapeutic strategy for treating human leukemia. Hepatocellular carcinoma (HCC) is worldwide accepted most common malignancies, as well as the second major cause of death among Chinese with cancer. There is an increasing evidence that could prove the potential effect of long non-coding RNAs (lncRNAs) to the biological performance of HCC. In present study, with high expression level in The Cancer Genome Atlas (TCGA) HCC samples, lncRNA MFI2 Antisense RNA 1 (MFI2-AS1) was closely related to poor prognosis and advanced stage among patients with HCC. In addition, up-regulation of MFI2-AS1 was further comfirmed in HCC tissues and HCC cell line. Ectopic expression of MFI2-AS1 stimulated the proliferation and metastasis of HCC cells, but knockdown MFI2-AS1 suppressed HCC cell proliferation and metastasis, indicating that MFI2-AS1 exerted oncogenic functions in the tumorigenesis of HCC. Simultaneously, compared with the negative control group, xenograft tumors in MFI2-AS1 group were characterized with poor growth, smaller volumes and less liver metastases. The post-transcriptional regulation of FOXM1 by MFI2-AS1 occured mechanistically, playing a role of competing with endogenous RNA (ceRNA) in HCC to sponge miR-134. Over-expression of MFI2-AS1 increased FOXM1 expression both at mRNA and protein level, whereas it was reducd by miR-134. Meanwhile, knockdown of miR-134 abolished the repression of shMFI2-AS1 on FOXM1 expression. Furthermore, we demonstrated that miR-134 reverses the impact of MFI2-AS1 on HCC proliferation and metastasis through regulation on FOXM1. Collectively, we determined that MFI2-AS1 crucially acted in HCC progression via functioning as miR-134 sponge to upregulating FOXM1 expression, and was conducive to the promotion of better understanding the direct diagnostics and iatreusiology of lncRNA in HCC.
