Project description:We collected the Superficial temporal artery (STA) tissues from patients with Moyamoya disease who underwent combined direct and indirect bypass surgery and patients with brain trauma requiring craniotomy in the Department of Neurosurgery, First Affiliated Hospital of USTC (Anhui Provincial Hospital). One part was fixed in 10% neutral formalin solution, and the other part was stored in a refrigerator at -80 ℃. All protocols using human specimens were approved by the ethics committee of the First Affiliated Hospital of USTC (Anhui Provincial Hospital). Written informed consent was obtained from all patients. All protocols were approved by the Institutional Review Board of the First Affiliated Hospital of USTC (Anhui Provincial Hospital).Total RNA was extracted from the STA tissues using Trizol reagent (Invitrogen, Carlsbad, CA, USA) according to the manufacturer's protocol. The integrity and concentration of RNA were detected using an Agilent Bioanalyzer 2100 system (Agilent Technologies, Santa Clara, Calif., USA), enriched and purified with Oligo (dT) -bearing magnetic beads. RNA sequencing was performed by Anoroad (Beijing, China).

Project description:This experiment is part of the FunGenES project (FunGenES - Functional Genomics in Embryonic Stem Cells partially funded by the 6th Framework Programme of the European Union, http://www.fungenes.org). The experiment was conducted at University of Cologne, Cologne, Germany. Goal of the experiment was RNA expression profiling in the first 10 days of differentiation in CGR8 cells. Materials and methods: CGR8 cells were cultivated as EBs without addition of selective reagents in hanging drop cultures in a timecourse experiment. After 7 days, EBs were plated in gelatin-coated 6-well plates. RNA was prepared from ES cells (day 0), EBs (day 1 to 7) and plated EBs (day 10). Culture conditions: ES cells were differentiated via hanging drop protocol into embryoid bodies. RNA isolation method: The RNA isolation was carried out following standard methods (on column, RNeasy Mini kit, Qiagen)

Project description:Chronic traumatic encephalopathy (CTE) is a neurodegenerative disease associated with exposure to repetitive head impacts, which is susceptible in elderly people with declined mobility, athletes of full contact sports, military personnel and victims of domestic violence. It has been pathologically diagnosed in brain donors with a history of repetitive mild traumatic brain injury (rmTBI), but cannot be clinically diagnosed for a long time. By the continuous efforts by neuropathologists, neurologists and neuroscientists in recent 10 years, an expert consensus for the diagnostic framework of CTE was proposed in 2021 funded by the National Institute of Neurological Disorders and Stroke. The new consensus contributes to facilitating research in the field. However, it still needs to incorporate in-vivo biomarkers to further refine and validate the clinical diagnostic criteria. From this, a single-center, observational cohort study has been being conducted by Tianjin Medical University General Hospital since 2021. As a pilot study of this clinical trial, the present research recruited 4 pairs of gender- and age-matched rmTBI patients with healthy subjects. Their blood samples were collected for exosome isolation, and multi-omics screening to explore potential diagnostic biomarkers in blood and its exosomes.
