Gallic acid chemoprevention of oral carcinogenesis

ABSTRACT: Naturally derived phytochemicals such as gallic acid (GA) exhibit multitargeted anticancer properties and favorable safety profiles, yet the molecular mechanisms underlying their chemopreventive effects in head and neck squamous cell carcinoma (HNSCC) remain incompletely defined. Using a 4 nitroquinoline 1 oxide (4NQO) induced oral carcinogenesis mouse model, we evaluated GA’s effects on tumor progression, and related molecular pathways. Phenotypic outcomes were assessed by histopathology, and proliferation markers. Transcriptomic changes were profiled by RNA sequencing, pathway enrichment and validation using RT qPCR. We report GA as a key modulator of transcriptional programs associated with oral carcinogenesis in a 4-nitroquinoline-1-oxide–induced mouse model. Comparative RNA sequencing of wild-type vehicle-treated (WtVeh) and GA-treated (WtGal) oral tissues revealed GA-dependent reprogramming of immune and stress-response pathways. Our data identifies unique molecular pathways associated with GA mediated oral cancer chemoprevention.

Transcriptional profile Lactobacillus plantarum WCFS1 : 1.5mM gallic acid (GA) treated cells

Project description:Whole genome transcriptional profiling was used to characterize the response of Lactobacillus plantarum WCFS1 human isolate during challenge with 1.5 mM gallic acid (GA). Twelve independent experiments were performed and mixed at random in groups of four for total of three RNA samples. The transcriptional profile reveals a massive induction of genes involved in transport and decarboxilation of gallic acid.

Expression data from 5azaC- or gallic acid-treated human lung cancer H1299 cell line

Project description:Gallic acid (also known as 3,4,5-trihydroxybenzoic acid, GA), a naturally occurring phenolic acid, is a major constituent of tea and red wine. It has been demonstrated that GA possess anti-cancer activities. We found the epigenetic effect of GA in tobacco-associated human cancer cell lines. In this dataset, we include the expression array data from human lung cancer H1299 cell line with or without the treatment of 5azaC or GA. These data were used to obtain genes upregulated in both 5azaC- orGA-treated H1299 cells.

Gallic Acid Pretreatment Mitigates Parathyroid Ischemia-Reperfusion Injury through Signaling Pathway Modulation

Project description:As a polyphenolic herbal extract, Gallic acid (GA) is known for its antioxidant and anti-inflammatory properties. However, its application in parathyroid ischemia-reperfusion injury (IRI) has not been well examined. This study aimed to elucidate the protective effects of GA pretreatment in a parathyroid IRI model and explore the underlying mechanisms.Hypoxia and hypoxia/reoxygenation models were established with primary parathyroid cells to explore the protective effect of GA.The results from sequencing and bioinformatic analyses indicated that GA might regulate MMP1, MMP9, FOSB, GSY2, DUSP5, TRPV1/3, TIAM1 and multiple signaling pathways in this process such as IL-17, AMPK, MAPK, Transient Receptor Potential (TRP) channels, cAMP and Rap1.

Large-scale Chemical Screen Identifies a Geroprotective Role of Gallic Acid in Premature Aging [ATAC-seq]

Project description:Gallic acid (GA) is a natural phenolic compound with antioxidant, anti-inflammatory, and antineoplastic properties. Previous studies also revealed that GA supplementation inhibit the decline of rat embryonic and rejuvenate the immune function in D-gal-induced aging accelerated mice. However, the role of GA in regulating senescence of human premature aging stem cells is unknown. We have demonstrated that GA showed beneficial effects in alleviating human mesenchymal stem cell (hMSC) senescence: (1) GA alleviated senescence by promoting stem cell self-renewal ability and down-regulating the expression of aging markers, including P16 and P21, in Werner syndrome (WS) hMSCs; (2) High levels of reactive oxygen species in total cell as well as mitochondria were both rescued by GA treatment; (3) GA also maintained epigenetic features, enhanced cell stemness, and improved mitochondrial homeostasis in WS hMSCs. Our data provide substantial evidence supporting that GA is a promising candidate agent to

Gene Expression Profile Analysis of Gallic Acid-induced Cell Death Process

Project description:Gallic acid is a natural phenolic compound that displays anti-cancer properties in clinically relevant cell culture and rodent models. To date, the molecular mechanism governing the gallic acid-induced cancer cell death process is largely unclear, thus hindering development of novel therapeutics. Therefore, we performed time-course long non-coding RNA sequencing (lncRNA-seq) to reveal the gene expression profiles at the early, middle, and late stages of the gallic acid-induced cell death process in human cervical cancer HeLa cells. This work provides a dataset with differentially expressed genes across different stages of cell death process during the gallic acid induction, which is important for further study on the control of this cell death mechanism.
