Project description:Given the gut microbiota involve aging processing, we performed comparative analysis of gut bacteriophage between older and young subjects using next-generation sequencing (NGS). In our previous study, we found that the Ruminococcaceae is higher in aged subjects comparing to young one. To identify the bacteriophage targeting to the Ruminococcaceae, we also access the composition of phage in the Ruminococcaceae (ATCC, TSD-27) after incubated with human stool samples. The Lactobacillus (ATCC, LGG) targeting phage was used as the control. The virome sequencing analysis using NGS indicated that Myoviridae are high enrich in young subjects and predominate in TSD-27 targeting phage.

Project description:Next generation sequencing (NGS) was performed to identify genes changed in ginseng upon Botrytis cinerea infection. The goal of the work is to find interesting genes involved in medical plant in response to fungi infection. The object is to reveal the molecular mechanism of medical plant defense.
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:RNA was isolated from 23 old barley plants (shoots and roots), line Rolap. PARE libraries were constructed for both barley organs, followed by sequencing of NGS libraries.
Project description:We report the methylation level of photodamage repair deficient plants 24h upon UV-C exposure. We determined the methlome changes genome wide and at photodamaged sites using NGS approaches.
