Project description:Microarray analysis is being performed with cultivated selections using custom designed arrays. Custom designed arrays include the design of microarray probes using clearly described bioinformatics methods. We have used the sequence data related to fungal resistance from Camellia Sp. and Arabidopsis thaliana available in the biological databases, to design these arrays. Results of this work will help us to understand the genes expressed during the blister blight and grey blight infection. Camellia sinensis 4x44k Microarray designed by Genotypic Technology Private Limited. (AMADID:043117)
Project description:Ulcerative colitis is a chronic inflammatory disorder for which a definitive cure is still missing. This is characterized by an overwhelming inflammatory milieu in the colonic tract where a composite set of immune and non-immune cells orchestrate its pathogenesis. Over the last years, a growing body of evidence has been pinpointing gut virome dysbiosis as underlying its progression. Nonetheless, its role during the early phases of chronic inflammation is far from being fully defined. Here we show the gut virome-associated Hepatitis B virus protein X, most likely acquired after an event of zoonotic spillover, to be associated with the early stages of ulcerative colitis and to induce colonic inflammation in mice. It acts as a transcriptional regulator in epithelial cells, provoking barrier leakage and altering mucosal immunity at the level of both innate and adaptive immunity. This study paves the way to the comprehension of the aetiopathogenesis of intestinal inflammation and encourages further investigations of the virome as a trigger also in other scenarios. Moreover, it provides a brand-new standpoint that looks at the virome as a target for tailored treatments, blocking the early phases of chronic inflammation and possibly leading to better disease management.
Project description:MicroRNAs (miRNAs) are a type of small non-coding RNAs, which play important roles in plant growth, development and stress responses. Tea (Camellia sinensis) prepared from tea tree is the oldest and most popular nonalcoholic beverages in the world, and has large economic, medicinal and cultural significance. Nevertheless, there are a few studies on the miRNAs and their functions in Camellia sinensis. We sequenced 9 small RNA libraries and 9 RNA-Seq libraries from roots, leaves and flowers tissues. Through comprehensive computational analyses of 9 small RNA profiles, we identified 200 conserved miRNAs of which 138 have not been reported, and 56 novel miRNAs with 33 have not been reported. Nearly, two thousands genes have significantly different expression levels in tissues. In order to identify targets of miRNAs, we sequenced two degradome profiles from leaves and roots, respectively. Totally, more than 3,000 putative targets of conserved miRNAs were identified in both degradome profiles by using the SeqTar algorithm. These results clearly enhanced our understanding about small RNA guided gene regulations in Camellia sinensis.
Project description:Self-inhibition of pollen tubes plays a key role in SI, but the underlying mechanism in Camellia oleifera is poorly understood. Collection of secreted proteins from Camellia oleifera pollen tubes and ovaries for high-throughput sequencing.
Project description:We report the expression analysis of seed kernel in Camellia oleifera cultivars. In total 221 cultivars are sequenced by the Illumina sequencing experiments to obtain the gene expression profiles.

Project description:This study aims to explore the relationship between the respiratory virome, specifically bacteriophages, HERV and the host response in ARDS and to assess their value in predicting the prognosis of ARDS.
Project description:Colorectal cancer (CRC) is one of the most common malignant tumors worldwide, occurring in the colon or rectum portion of large intestine. With marked antioxidant, anti-inflammation and anti- tumor activities, Camellia nitidissima Chi has been used as an effective treatment of cancer. The azoxymethane/dextran sodium sulfate (AOM/DSS) induced CRC mice model was established and the prevention effect of Camellia nitidissima Chi extracts on the evolving of CRC was evaluated by gross examination, histopathological inspection, serum biochemistry analysis, combined with nuclear magnetic resonance (NMR)-based metabolomics and correlation network analysis. The results showed that Camellia nitidissima Chi extracts could significantly inhibit AOM/DSS induced CRC, relieve the colonic pathology and ameliorate the serum biochemistry, and could significantly reverse the disturbed metabolism towards the normal state. Moreover, the butanol fraction showed a better efficiency than the water-soluble fraction of Camellia nitidissima Chi. The study pave the way for further development of Camellia nitidissima Chi extracts as a potent CRC inhibitor. In this work, rats were divided into control group, carcinoma group, and two drug groups of JHC and CNC. The acronyms JHC means the water-soluble fraction of Camellia nitidissima Chi. The acronyms CNC means the butanol fraction of Camellia nitidissima Chi.
