Project description:Honokiol (HNK), one of the main medicinal components in Magnolia officinalis, possesses antimicrobial activity against a variety of pathogenic bacteria and fungi.S. cerevisiae is a model eukaryote used for investigating the cellular and molecular mechanisms of anti-fungal drugs. To explore the molecular mechanism of its anti-fungal activity, we determined the effects of HNK on the mRNA expression profile of Saccharomyces cerevisiae using a DNA microarray approach.
Project description:Cornus officinalis Sieb. et Zucc., a perennial woody plant which is recognized with high medicinal, economic and ecological values, has been used as traditional Chinese medicine (TCM) for thousands of years in China. Modern pharmacological research has revealed that cornel iridoid glycosides (CIGs, e.g. loganin and morroniside) in dried pericarp of C. officinalis have significant medicinal activities for strengthening immune functions. However, little is known on the molecular processes responsible for the medical properties of this species, owing to the absence of genomic resources such as available sequences of key enzyme genes in biosynthetic pathways. In this study, the RNA sequencing data of C. officinalis were first generated and used for transcriptome analysis. A total of 54,827 unigenes with an average length of 817 bp, an N50 of 1,379 bp, and an average GC content of 44.91% were yielded by de novo assembly, of which 31,780 unigenes were successfully annotated. As potential molecular markers, 121, 118, 96, 89, and 82 transcription factors belonged to bHLH, MYB, PHD, WRKY, and AP2-ERF were further analyzed, respectively. The results of qRT-PCR confirmed that geraniol 10-hydroxylase (G10H) and loganin synthase (SLS) were differentially expressed in fruits and leaves during different growing stages. Furthermore, we found that loganin accumulation was positively related to G10H expression but was negatively correlated with SLS expression. Collectively, the genomic information and gene expression results presented in this study will be helpful for future studies on gene discovery and molecular process of loganin synthesis in C. officinalis.

Project description:Colorectal cancer (CRC) is a major cause of cancer mortality and a serious health concern worldwide. Vitamin D deficiency is associated with high CRC incidence and mortality, suggesting a protective effect of vitamin D against this neoplasia. Although the antiproliferative and prodifferentiation action of active vitamin D (1alpha,25-dihydroxyvitamin D3, 1,25(OH)2D3) on colon carcinoma cells is well documented, its potential effects on CRC stroma are unknown. Here, we show that high vitamin D receptor (VDR) expression in tumor stromal fibroblasts is associated with better overall and progression-free survival in a large cohort of CRC patients, irrespective of its expression in carcinoma cells. Consistently, 1,25(OH)2D3 inhibits the activation of patient-derived normal and cancer-associated fibroblasts, and their pro-migratory effect on carcinoma cells. Importantly, we show by global transcriptomic analyses that 1,25(OH)2D3 regulates cancer-associated fibroblast gene expression and imposes a gene signature that is associated with longer overall and disease-free survival of CRC patients. Moreover, expression of two genes from the signature, CD82 and S100A4, correlates with stromal VDR expression and clinical outcome in CRC. This study provides the first evidence that vitamin D has protective effects against CRC through the regulation of stromal fibroblasts. Characterization of 1,25(OH)2D3 action on gene expression in primary cultures of colon normal and tumor fibroblasts established from samples from colorectal cancer patients. RNA from seven paired normal and tumor fibroblast primary cultures treated with 1,25(OH)2D3 or vehicle for 48 h were analyzed.
