Abstract
CircRNA/miRNA/mRNA axis has been reported to play crucial regulatory roles in multiple cancers, including hepatocellular carcinoma (HCC). In addition, recent investigations revealed that aloin exerted anti-tumor functions in HCC. However, the underlying mechanism of aloin on anti-tumor functions in HCC remained elusive. Therefore, this study aimed to investigate whether circRNA/miRNA/mRNA axis medicated the anti-tumor effect of aloin in HCC. Cell viability, invasion, apoptosis and autophagy were accessed by cell counting kit-8 (CCK-8), transwell invasion assay, flow cytometry, Western blot and immunofluorescence analysis, respectively. Expression levels of circ_0011385, miR-149-5p and WT1 mRNA were determined using qRT-PCR assay. Binding sites between miR-149-5p and circ_0011385 or WT1 were predicted in starBase database. The binding relationship among circ_0011385, miR-149-5p and WT1 were verified by dual-luciferase reporter assay and RNA immunoprecipitation. Besides, the rescue experiments were performed by co-transfection with cric_0011385 overexpression plasmid, si-cric_0011385, miR-149-5p mimic and inhibitor, WT1 pDNA and si-WT1 in HCC cells. Furthermore, tumor growth was also investigated in the xenograft mouse model. Aloin inhibited HCC proliferation and invasion as well as promoted apoptosis and autophagy both in vitro and in vivo. Besides, aloin suppressed circ_0011385 expression. Overexpressed circ_0011385 partially reversed the anti-tumor effect of aloin on HCC. In addition, it was revealed that the circ_0011385, miR-149-5p and WT1 genes were abnormally expressed in HCC. Furthermore, the binding interactions between circ_0011385, miR-149-5p and WT1 were predicted and confirmed. Moreover, the effect of circ_0011385 on the anti-tumor role of aloin in HCC was rescued by miR-149-5p mimics. MiR-149-5p regulated HCC progression via modulating WT1. Aloin suppressed cell proliferation, invasion and tumor growth and promoted apoptosis and autophagy in HCC through regulating circ_0011385/miR-149-5p/WT1 axis. Aloin may be a potential candidate drug for HCC treatment.Abbrevations: HCC: Hepatocellular carcinoma; ceRNA: competing endogenous RNA; miRNA: microRNA; MREs: miRNA response elements; WT1: Wilms' tumor 1; MMP-2: Matrix metalloproteinase; EMT: epithelial-mesenchymal transition; GADPH: glyceraldehyde 3-phosphate dehydrogenase; WT: wild type; MUT: mutant type; DMEM: dulbecco's modified eagle medium.

Wan L, Zhang L, Fan K, Wang J. Aloin promotes A549 cell apoptosis via the reactive oxygen species‑mitogen activated protein kinase signaling pathway and p53 phosphorylation. Mol Med Rep 2017; 16:5759-5768. [PMID: 28901386 DOI: 10.3892/mmr.2017.7379] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2016] [Accepted: 03/06/2017] [Indexed: 01/09/2023] Open
Abstract
Aloin has the potential to be a novel anticancer agent in cancer therapies. However, the detailed anticancer effect of Aloin remains to be fully elucidated. The present study analyzed the p53‑dependent mechanisms in response to Aloin treatment. Using the p53‑proficient A549 cells, an Aloin‑induced apoptotic cell model was established, which was used to evaluate the potential underlying molecular mechanisms. The results demonstrated that 200, 300 and 400 µM Aloin induced intrinsic cell apoptosis, which was further confirmed by disruption of the mitochondrial membrane potential, elevation of cytosolic Ca2+ levels, and activation of B‑cell lymphoma 2 (Bcl‑2) homologous antagonist killer, Bcl‑2 X‑associated protein, p53 upregulated modulator of apoptosis and phorbol‑12‑myristate‑13‑acetate‑induced protein 1. Aloin‑induced apoptosis was also accompanied by the induction of p53 phosphorylation on Serine (Ser)15, Threonine 18, Ser20 and Ser392; however, there were no significant differences in the expression of p53 and mouse double minute 2 homolog. Aloin‑induced apoptosis was reactive oxygen species (ROS)‑ and c‑Jun/p38‑dependent, as specific inhibitors for ROS, phosphorylated (p)‑c‑Jun and p‑p38 may attenuate Aloin‑induced A549 cell proliferating inhibition. In conclusion, these results suggested that Aloin may induce apoptosis in A549 cells via the ROS‑mitogen activated protein kinase signaling pathway, with p53 phosphorylation. These results implicate Aloin as a potential therapeutic agent for the treatment of lung cancer.

Abstract
Aloe arborescens Miller (Family Asphodelaceae) is a member of genus Aloe, which is used in traditional medicine to cure various diseases. The extracts of the plant have been reported to possess anticancer, immunomodulator, antidiabetic, anti-inflammatory and antioxidant activities. The phytochemical investigations have revealed diverse chemical constituents, including phenolics [anthraquinones, anthrones, pyrones, chromones and coumarins], polysaccharides [arborans [(1-4) linked glucomannans, polysaccharide (A, B and C): (A: a linear (1-6)-O-α-glucan, B: a branching (1-2)-O-l-arabinose with (1-2)-O-d-galactose linkages and C: (1-4)-O-β-mannan with 18% acetyl group)]], glycoproteins and carboxypeptidase enzyme. There are many reports, describing the different methodologies developed to perform chemical analysis as well as, separation, detection and identification of these constituents. Different chromatographic techniques were applied such as gas chromatography (GC), high-performance liquid chromatography (HPLC), liquid chromatography-electrospray ionization coupled with mass spectroscopy (LC-ESI/MS/MS) and gel filtration chromatography. Also the isolated compounds were identified based on the spectroscopic analysis; ultraviolet-visible spectroscopy (UV-vis), infra-red spectroscopy (IR), mass spectroscopy (MS) and nuclear-magnetic resonance (NMR). This study aims to pinpoint the active components besides finding out new structural leads for future drugs. Therefore, the review is targeted to provide evidence reported in the relevant literature on qualitative and quantitative research to assist scientists in isolation and characterization of bioactive compounds in A. arborescens.

Abstract
Barbaloin is C-glucoside of aloe emodin anthrone which is found in the plant name as Aloe vera is a perennial succulent (Liliaceal), also called the healing plant. Barbaloin have variety of pharmacological activity such as strong inhibitory effect on histamine release, anti-inflammatory, cathartic, antiviral, antimicrobial, anticancer, antioxidant activity and alternative for pharmaceutical or cosmetic applications. The peak amount of barbaloin was reached about 3 h after oral administration. Concentration of barbaloin in Aloe vera leaves was shown to depend on the leaf part, age, and position of the leaf. Young leaves contain more barbaloin compared to old one. Various researches have been done on barbaloin but still the relationship between the barbaloin and its overall effect has not been clarified. A more specific perceptive of the pharmacological activities of barbaloin is required to develop for pharmaceutical purpose. Many attempts have been made regarding its isolation, biological activity to examine their effects, and clarify their functional mechanism. This review gives a brief idea about its uses, ethnomedicinally and commercially important analytical techniques and their pharmacological activities.

Abstract
Metabolite profiling of four different-sized Aloe vera plants was performed using gas chromatography-ion trap-mass spectrometry (GC-IT-MS) and ultra performance liquid chromatography-quadrupole-time of flight-mass spectrometry (UPLC-Q-TOF-MS) with multivariate analysis. Amino acids, sugars, and organic acids related to growth and development were identified by sizes. In particular, the relative contents of glucose, fructose, alanine, valine, and aspartic acid increased gradually as the size of the aloe increased. Anthraquinone derivatives such as 7-hydroxy-8-O-methylaloin, 7-hydroxyaloin A, and 6'-malonylnataloins A and B increased gradually, whereas chromone derivatives decreased continuously as the size of the aloe increased. The A30 aloe (size = 20-30 cm) with relatively high contents of aloins A and B, was suggested to have antioxidant components showing the highest antioxidant activity among the four different sizes of aloe. These data suggested that MS-based metabolomic approaches can illuminate metabolite changes associated with growth and development and can explain their change of antioxidant activity.
