Transcriptome and proteome analysis of the antitumor activity of maslinic acid against pancreatic cancer cells

ABSTRACT: Maslinic acid (MA) is a triterpenoid compound of natural abundance in olive plants possessing numerous biological activities. The effect and molecular mechanism of MA on pancreatic cancer cells remain elusive. Here, we explored the anti-tumor activity of MA on human pancreatic cancer cells and the potential underlying molecular mechanism. The anti-cancer effects of MA on whole-cell processes, including proliferation, migration, and invasion in pancreatic cancer cells, were systematically assessed by colony formation, transwell, and migration assays. The search for potential therapeutic targets was achieved via transcriptomics and proteomics analyses. MA was demonstrated to inhibit the proliferation, migration, and invasion of PANC-1 and Patu-8988 cells, but induced apoptosis of these cells. Several key candidate genes and proteins of functional relevance for the anti-tumor activity of MA were identified through the association analysis of transcriptomics and proteomics. To our knowledge, this is the first transcription and proteomics-based comprehensive analysis of the mechanism of MA against pancreatic cancer. The findings demonstrate that MA holds promise as a therapeutic drug for managing pancreatic cancer.

Maslinic acid-enriched diet decreases intestinal tumorigenesis in Apc(Min/+) mice through transcriptomic and metabolomic reprogramming

Project description:Chemoprevention is a pragmatic approach to reduce the risk of colorectal cancer, one of the leading causes of cancer-related death in western countries. In this regard, maslinic acid (MA), a pentacyclic triterpene extracted from wax-like coatings of olives, is known to inhibit proliferation and induce apoptosis in colon cancer cell lines without affecting normal intestinal cells. The present study evaluated the chemopreventive efficacy and associated mechanisms of maslinic acid treatment on spontaneous intestinal tumorigenesis in Apc(Min/+) mice. Twenty-two mice were randomized into 2 groups: control group and MA group, fed with a maslinic acid-supplemented diet for six weeks. MA treatment reduced total intestinal polyp formation by 45% (P<0.01). Putative molecular mechanisms associated with suppressing intestinal polyposis in Apc(Min/+) mice were investigated by comparing microarray expression profiles of MA-treated and control mice and by analyzing the serum metabolic profile using NMR techniques. The different expression phenotype induced by MA suggested that it exerts its chemopreventive action mainly by inhibiting cell-survival signaling and inflammation. These changes eventually induce G1-phase cell cycle arrest and apoptosis. Moreover, the metabolic changes induced by MA treatment were associated with a protective profile against intestinal tumorigenesis. These results show the efficacy and underlying mechanisms of MA against intestinal tumor development in the Apc(Min/+) mice model, suggesting its chemopreventive potential against colorectal cancer.

The Anti-Arthritis Effect of Olive-Derived Maslinic Acid in Mice is Due to its Promotion of Tissue Formation and its Anti-Inflammatory Effects.

Project description:SCOPE: A previous study demonstrated that intake of olive pomace extract containing maslinic acid (MA), a triterpene, effectively prevents and alleviates arthritis in animals and humans. Here, the molecular mechanisms involved in the anti-arthritis effect of MA have been elucidated by determining gene expression changes induced by olive-derived MA intake in collagen antibody-induced arthritis (CAIA) mice. METHODS AND RESULTS: Mice are divided into the untreated (CT), CAIA (CA), and CAIA administered MA (CA + MA) groups. The CA + MA mice are fed MA at a daily dose of 200 mg kg-1 of body weight from day 1. CAIA is then induced on day 8 and evaluated on day 12. Arthritis symptoms are alleviated, and the gene expression of inflammatory cytokines is reduced in the CA + MA group compared with the CA group. A DNA microarray analysis of synovial membranes reveals that MA alters the expression levels of genes related to inflammation, including glucocorticoid responses, immune responses, and the extracellular matrix. CONCLUSIONS: The preventive effect of MA on arthritis is attributable to the promotion of tissue formation as well as suppression of inflammation in the synovium via inactivation of Toll-like receptor signaling and downregulation of leukotrienes through the glucocorticoid receptor.

A time-course profiling of the effects of maslinic acid on mRNA expression of chemically induced Raji cells.

Project description:Maslinic acid is a novel phytochemical reported to exert prominent anti-cancer effects and it was hypothesized that this compound induces cellular apoptosis through the activation of the mitochondrial apoptotic pathway (Martin et al, 2007) — thereby resulting in significant inhibition of cell proliferation in a dose-dependent manner (Reyes-Zurita et al, 2009). Prior studies on maslinic acid in its function as a time-dependent inhibitor in both tumorigenesis and inflammation events by targeting multiple signaling pathways; particularly the NF-ĸB, MAPK (Li et al, 2010; Yap, et al, 2011) and JNK (Reyes-Zurita et al, 2011) pathways were mostly based on proteomic analyses (Li et al, 2010; Yap et. al., 2011). However, these results may not depict an accurate scenario of the signaling networks involved due to protein degradation, alternate splicing and extensive post-translational processing. Hence, this study aimed to construct a temporal-based global gene expression profile of the effects of maslinic acid by using the microarray technology. The aim of this project is to construct the complete global mRNA profile of the effects of maslinic acid in inhibiting early-antigen formation in Raji cells.

RNA Affymetrix microarray analysis of colonic mucosal layer of Apc Min/+ mice fed or not with maslinic acid.

Project description:This experiment reports the RNA microarray data from the microarray analysis performed to the RNA isolated from colonic mucosal layer of Apc Min/+ mice. Apc Min/+ mice develop polyps in both the small and large intestine, with a greater incidence of intestinal adenomas observed in the former. We wanted to evaluate if maslinic acid (MA), a natural pentacyclic triterpene widely present in dietary plants and in olive fruit skins, could prevent spontaneous intestinal tumorigenesis in Apc Min/+ mice and through with mechanism MA executes its function. To do so, Apc Min/+ mice were fed for 6 weeks with a standard diet (control animals) or with the same diet supplemented with 100 mg of MA/kg feed (MA-treated animals). After 6 weeks, animals were killed and large intestine of each dead mouse was removed and placed on a plastic plate that was kept at 4ÂºC. After removal of the rectum, the colon was opened longitudinally with fine scissors, and mucus and feces were washed away. The colonic mucosal layer was incubated in Trizol for 3 min and scraped off of the muscle layer with the edge of a sterile glass slide. Cells were transferred into 800 microL trizol. Total RNA was isolated by using the Trizol method according to the manufacturer's protocol. Subsequently, it was purified by using the RNeasy Mini kit and digesting it with DNase I (Qiagen) according to the manufacturer's protocol. RNA pellets were resuspended in DEPC-treated, RNase-free water, and their purity and quantity were determined spectrophotometrically by using the NanoDrop ND-1000. RNA samples were considered suitable for further processing if their absorbance ratio 260/280 was higher than 1.9. Integrity was tested by using lab-on-a-chip technology on the BioAnalyzer 2100.

A set of 72 differentially expressed miRNAs provide a molecular signature for pancreatic cancer

Project description:MicroRNAs (miRNAs) are short single-stranded RNA molecules that have a critical role in the regulation of gene expression. Alterations in miRNA expression levels have been observed in multiple tumor types and there is clear evidence on their active involvement in cancer development. Here, a comprehensive miRNA expression profiling in 16 pancreatic cancer cell lines and four normal pancreatic samples provided a specific molecular signature for pancreatic cancer and enabled us to identify 72 differentially expressed miRNAs with approximately half of them being up- and half downregulated in cancer cells as compared to normal samples. Of these, miR-31 was selected for further functional analyses based on its interesting M-bM-^@M-^\on-offM-bM-^@M-^] type expression profile, i.e. very low or even absent expression in normal pancreas and in six of the pancreatic cancer samples but extremely high expression in the remaining ten cell lines. Quite unexpectedly, both the inhibition of miR-31 in AsPC-1 and HPAF-II pancreatic cancer cells with high endogenous expression and forced expression of miR-31 in MIA PaCa-2 with low endogenous levels led to reduced cell proliferation, migration and invasion. More importantly, in AsPC-1 cells further enhancement of miR-31 also resulted in reduced cell migration and invasion, implicating that the level of miR-31 is critical for these phenotypes. We also identified novel miR-31 target genes, APBB2 and RSBN1, that might contribute to cancer pathogenesis. This study highlights a specific miRNA expression pattern in pancreatic cancer and reveals that manipulation of miR-31 expression leads to reduced cell migration and invasion in pancreatic cancer. 16 pancreatic cancer cell lines and 4 normal pancreatic RNA samples were hybridized on Agilent vs1 miRNA microarrays. Pool of four normal samples was hybridized on each slide to allow normalization between slides.
