Project description:Gastric cancer is one of the most common malignant tumors. Asia has a high incidence of gastric cancer globally. South Korea, Mongolia, Japan and China are the four countries with the highest incidence of gastric cancer in the world. Gansu province in China has the estimated age-standardized incidence rates and mortality rates by Chinese standard population of 62.34/100,000 and 36.94/100,000, respectively, in 2012, which are much higher than the average level of China (22.06/100,000 and 15.16/100,000) in the same year. As a high incidence area of gastric cancer in China, Wuwei city in Gansu province has the prevalence of gastric cancer almost 5 times higher than the average level nationwide. In this study, the cancer tissues and matched adjacent normal mucosa tissues of 5 patients with early gastric cancers who were treated with ESD in Gansu Wuwei Tumor Hospital and the First Hospital of Lanzhou University were collected. All of the patients are from Gansu, China. MicroRNA array was used to find the differences in microRNAs expression profile between the early gastric cancer tissues and the para-cancer normal tissues. It is expected to explore the reasons of the abnormal high incidence of gastric cancer in Gansu Province, China, from the aspect of microRNAs expression profile characteristics.
Project description:Reaumuria soongorica (Pall.) Maxim., a typical species of desert plant, presents excellent tolerability to adverse environment. Until yet, little is known about the molecular mechanisms of stress tolerance in R. soongorica. Herein, we used the RNA-seq to study the transcriptome of R. soongorica leaves
Project description:An TMT-based quantitative crotonylome analysis was performed on the crotonylated proteins enriched from the chloroplast extracts of the normal and salt-treated wheat seedling leaves by using affinity purification and LC-MS/MS. The crotonylated peptides from wheat chloroplast extracts were enriched by using anti-crotonyllysine mouse mAb (Clone 4D5) antibody (PTM BioLabs, HangZhou, China PTM-501 and Nano LC-MS/MS was performed by using a Dionex rapid-separation liquid chromatography system interfaced with a Q Exactive HF (Thermo Fisher Scientific).
Project description:Five healthy Laoshan dairy goats (four years old, third lactation) from Qingdao Laoshan dairy goat primary farm (Shandong Province, China) were used. The mammary gland samples were collected surgically after general anaesthesia using Xylazine Hydrochloride injection solution (Huamu Animal Health Products Co., Ltd. China) at corresponding lactation stage, including early, peak and late lactations.
