Project description:Fungal-fungal interactions frequently result in alterations to the metabolomic profiles of the interacting fungi, with potential ramifications in both industrial and agricultural contexts. In this present study, an endophytic strain of Fusarium sp. MF20 was isolated from the fruiting bodies of Sanghuangporus vaninii. An optimized co-culture system was then established to explore the changes in metabolite profiles resulting from the fungal-fungal interaction, employing a comprehensive analysis integrating transcriptomics and metabolomics. This foundational work paves the way for the enhanced industrial exploitation of Sanghuangporus, a medicinally valuable and rare fungi
Project description:The common Eastern bumble bee Bombus impatiens is native to North America and is the main commercially reared pollinator in the Americas. There has been extensive research on this species related to its social biology, applied pollination, and genetics. The genome of this species was previously sequenced using short-read technology, but recent technological advances provide an opportunity for substantial improvements. This species is common in agricultural and urban environments, and heavy metal contaminants produced by industrial processes can negatively impact it. To begin to identify possible mechanisms underlying responses to these toxins, we used RNA-sequencing to examine how exposure to a cocktail of four heavy metals at field-realistic levels from industrial areas affected B. impatiens worker gene expression.
Project description:This is a single blind, case control, multicenter study jointly developed by Zhongshan Hospital of Fudan University, Shanghai Public Health Clinical Center, Shanghai Xuhui Central Hospital, Qingpu Branch of Zhongshan Hospital Affiliated to Fudan University, and Shanghai Singlera Genomics Company. The enrolled population will include positive group, precancerous lesions and healthy control group, which is expected to enroll 2,430 participants. The primary objective is to establish molecular testing methods for non-invasive screening and early diagnosis of digestive system cancers through ctDNA methylation and mutation, cfDNA and ctDNA fragment size, and end motif based model (for esophageal, gastric, colorectal cancer), and through ctDNA methylation detection, ctDNA low-pass WGS, miRNA7 and CTC detection and analysis technology based model (for hepatocellular carcinoma). The sensitivity and specificity of the models in cancer early detection will be evaluated.
Project description:We applied small RNA Solexa sequencing technology to identify microRNA expression in human liver samples from surgically removed liver tissues including three normal liver tissues (distal normal liver tissue of liver hemangioma), an hepatitis B virus (HBV)-infected liver, a severe chronic hepatitis B liver, two HBV-related hepatocellular carcinoma (HCC), an hepatitis C virus (HCV)-related HCC, and an HCC without HBV or HCV infection. All samples were collected with the informed consent of the patients and the experiments were approved by the ethics committee of Second Military Medical University, Shanghai, China. We investigated the miRNome in human normal liver and suggested some deregulated abundantly expressed microRNAs in HCC. center_name: National Key Laboratory of Medical Immunology & Institute of Immunology, Second Military Medical University, Shanghai, China.
Project description:Three individual patient-originated (Scalp trauma; ages 37, 46 and 57) DPCs were used for the studies. Dermal papilla cells, derived from the frontal scalp of 3 women, were treated with normal medium (Ctrl group) and medium containing 10-7 M corticotropin-releasing hormone (CRH group) for 72 h. Proteins were extracted and digested with trypsin for 4D label-free quantitative proteomics (Shanghai Applied Protein Technology Co., Ltd.).
Project description:To reveal the proteins of the ubiquitination system possibly interacting with MeCP2, NIH3T3 cells were synchronized by serum starvation for 36 hours and collected following 15% FBS stimulation for 3 or 9 hours. Total protein (1 mg) was incubated with anti-Mecp2 (5 μg) overnight at 4 °C with constant mixing. IgG was used as the negative control. Then, antibody was incubated with Dynabeads for 2 h with shaking. After three washings, retained proteins were eluted using 30 μl of SDS lysis buffer. Eluted Mecp2-associated cellular proteins were separated by SDS-PAGE and stained with Coomassie blue. Trypsin was used to digest stained protein bands. An Orbitrap Elite mass spectromete was used to analyze the digested samples by Applied Protein Technology Co., Ltd. (Shanghai, China). Using Mascot as a search engine, fragment spectra were scanned against the Uniprot database to identify proteins.
Project description:For liquid GST pull-down tandem with LC-MS/MS analysis, the gels were cut and sent to Shanghai Bioprofile (Shanghai, China) for analysis.
